MAINTENANCE FORMS AND PROCEDURES Department of the Army forms and procedures used for equipment maintenance will be those prescribed by DA Pam 738-750 as contained in the Maintenance Management Update. # 1-3. CORROSION PREVENTION AND CONTROL (CPC) The vehicle has a total service life of 20 years which allows for extended periods of operation in a corrosive environment. A corrosive environment includes exposure to high humidity, salt spray, road de-icing chemicals, gravel damage, and atmospheric contamination. No action beyond normal washing and repair of damaged areas is needed to control corrosion. To prevent moisture accumulation, drain holes are provided on structural and sheet metal areas where needed, and stowage boxes are provided with seals and baffled drains. Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion problems with the vehicle be reported so that the problem can be corrected and improvements made to prevent the problem in the future. While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem. If a corrosion problem is identified, it can be reported using form SF 368 (Product Quality Deficiency Report). Using keywords such as "corrosion", "rust", "cracking", or "deterioration" will ensure that the information is identified as a CPC problem. Form SF 368 should be submitted to the address specified in DA PAM 738-750. ### 1-4. DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE Command decision, according to the tactical situation, will determine when the using organization is to destroy a vehicle. A destruction plan will be prepared by the using organization, unless one was prepared by a higher authority. For general vehicle destruction procedures, refer to TM 750-244-6, Procedures for Destruction of Tank-Automotive Equipment to Prevent Enemy Use (U.S. Army Tank-automotive and Artillery Command). {45}------------------------------------------------ ## 1-5. REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR) If your vehicle needs improvement, let us know. Send us an EIR. You, the user, are the only one who can tell us what you don't like about your equipment. Let us know why you don't like the design or performance. Put it on an SF 368.

Vehicle Classification {68}------------------------------------------------ ## Section III. PRINCIPLES OF OPERATION 1-14. Powertrain ![](_page_68_Picture_3.jpeg) Figure 1-9. Powertrain The Powertrain for the vehicle is provided by a diesel engine (1, Figure 1-9) which is coupled directly to an automatic transmission (2). Power from the automatic trans-mission is supplied to the transfer case (3) and on to the front steering axle (4) and rear drive axle (5) through a series of drive shafts and universal joints. The capability of the powertrain is enhanced by the use of an seven-speed transmission. a. Engine. The vehicle is equipped with a Caterpillar model 3116 ATAAC diesel engine (1, Figure 1-9), rated at 225 hp (168 kW). {69}------------------------------------------------ ## 1-14. POWERTRAIN (CONT) ![](_page_69_Figure_2.jpeg) Figure 1-9. Powertrain (Cont) b. Transmission. The vehicle is equipped with a fully automatic, electronically controlled, seven-speed close-ratio Allison transmission Model MD3070PT (2, Figure 1-9). The WTEC II Transmission ECU Pushbutton Shift Selector (TEPSS) has a velcro cover and the WTEC III Transmission Pushbutton Shift Selector (TPSS) does not have a velcro cover. (1) The WTEC II TEPSS (7) or WTEC III TPSS (7) is located in the instrument panel, to the Operator's left. (2) The transmission defaults to Neutral (N) whenever electrical power is removed from the vehicle. When electrical power is first supplied to the vehicle, the WTEC II TEPSS or WTEC III TPSS will momentarily display MODE ON in the LED display. MODE ON display will disappear and N will be left in the LED display. This lets you know that the transmission is in highway mode and Neutral range (N), (3) The Drive (D) gear selection is used for normal driving conditions. The transmission will engage 2nd gear when D is selected and the vehicle is stopped. The LED display will illuminate 7 2, indicating that the transmission is in 2nd gear and there are seven forward gears available. Low gear (1st gear), is available only through manual selection by pressing the down arrow button until 1 1 is displayed in the LED display. You may manually downshift or upshift to a lower or higher gear range as required. However, the transmission will not downshift to a lower gear if the engine speed is too high for the gear selected. Selecting a specific gear; for example, 3rd; will prevent the transmission upshifting past the selected gear. {70}------------------------------------------------ ![](_page_70_Figure_1.jpeg) Figure 1-9. Powertrain (Cont) (4) When the MODE button is pressed, MODE ON will illuminate in the LED display. If the vehicle is stopped; the LED display will illuminate 5 MODE ON 2, indicating that the transmission is in 2nd gear and there are five forward gears available. This off-road mode is useful if road or load conditions require the use of a lower gear range for maximum torque. The vehicle must be completely stopped and engine operating at idle speed before the transmission will allow you to shift from a forward gear to Reverse (R) gear. (5) The transmission may include an electrically controlled PTO (8). The PTO provides power to a hydraulic pump, which powers the 11K Self-Recovery Winch (SRW) (if equipped). The transmission will not shift from Neutral (N) if the PTO is engaged and the winch switch is in the on position. c. Transfer Case. The transfer case (3) contains the gears and clutches that provide the transmission (2) with the seventh gear. The transfer case delivers power from the transmission to the front driveshaft and rear driveshaft. In normal driving conditions, the transfer case splits the output torque of the transmission, providing 70 percent of the torque to the rear and 30 percent to the front. In 1st gear, or any time MODE ON is illuminated in LED display, the output torque of the transmission is split evenly between front and rear. {71}------------------------------------------------ ### 1-15. ENGINE AIR INTAKE SYSTEM ![](_page_71_Picture_2.jpeg) Figure 1-10. Engine Air Intake System The Engine Air Intake System consists of a dry-type intake air cleaner (1, Figure 1-10), turbocharger (2), and a Charge Air Cooler (CAC) (3). The turbocharger increases engine horsepower by delivering a higher volume of air to the engine. The turbocharger compresses the air and delivers it to the CAC. The air flows through the CAC which cools the air before it is delivered to the engine cylinders. The air aspiration tubes (4) pass the cooled and compressed air to the engine inlet manifold (5). The compressed air/fuel mixture allows more complete burning of the fuel. The result is an increase in horsepower and lower emissions. {72}------------------------------------------------ ### 1-16. FUEL SYSTEM ![](_page_72_Figure_2.jpeg) Figure 1-11. Fuel System The Fuel System consists of a 56 gal (212 L) capacity, 54 gal (204 L) useable fuel tank ■ (1, Figure 1-11), fuel priming pump and fuel/water separator (2), fuel shutoff solenoid (3), fuel governor (4), and secondary fuel filter (5). (1) The fuel priming pump is hand actuated and is used to pump fuel to the fuel governor after maintenance is performed on certain parts of the fuel system. (2) The fuel/water separator removes water and large solid particles from the fuel before it is passed to the fuel governor. (3) The fuel governor responds to input from the accelerator pedal and causes an increase or decrease in engine speed. The fuel governor adjusts the amount of fuel delivered to the engine as engine speed changes. {73}------------------------------------------------ ## 1-16. FUEL SYSTEM (CONT) ![](_page_73_Picture_2.jpeg) Figure 1-11. Fuel System (Cont) (4) The secondary fuel filter removes finer particles from the fuel before it reaches the cylinder head. (5) The vehicle is also equipped with an ether quick start system for starting the engine when the outside temperature is below 32°F (0°C). The ether quick start system is composed of an ether cylinder (6), ether valve (7), two ether nozzles (8), and an ether sensor switch (9). The ether sensor switch detects the temperature of the engine coolant and disables the ether valve if the coolant temperature is above 100°F (38°C). {74}------------------------------------------------ ![](_page_74_Figure_1.jpeg) Figure 1-12. Cooling System The Cooling System protects the engine, transmission, and air compressor by providing a means of removing the heat generated during operation of the vehicle. (1) The radiator pressure cap (1, Figure 1-12), in combination with the ethylene glycolbased antifreeze, effectively raises the boiling point of the coolant to well above 212°F (100°C). (2) The thermostat (2) helps the engine to warm up quickly by remaining closed until the coolant temperature reaches approximately 199°F (93°C). When the coolant temperature reaches approximately 199°F (93°C), the thermostat opens and coolant is circulated through the water jacket in the engine to maintain the correct operating temperature for the engine. Coolant is drawn from the radiator (3), through the transmission oil cooler (4), and circulated through the cooling system by the water pump (5). Heat is drawn from the radiator by the engine fan pulling air over the radiator cooling fins. (3) A radiator overflow tank (6) is provided to allow for expansion of the coolant. The radiator overflow tank also serves as the point where new coolant is introduced into the cooling system. The radiator overflow tank has two sight glasses; the upper sight glass (7) indicates the level to fill to with engine shut down. If coolant is not visible in the lower sight glass (8), do not operate the vehicle. {75}------------------------------------------------ ## 1-17. COOLING SYSTEM (CONT) ![](_page_75_Picture_2.jpeg) Figure 1-12. Cooling System (Cont) (4) The engine fan (9), with pneumatic fan clutch (10), is activated by the water temperature sensor (11). Whenever this sensor detects a high engine temperature condition, air pressure is removed from the fan clutch and the engine fan is engaged. (5) Positioning the radiator fan off switch (12) to the on position keeps the engine fan from engaging. {76}------------------------------------------------ ![](_page_76_Figure_1.jpeg) Figure 1-12. Cooling System (Cont) (6) The WATER TEMP gage (15) on the instrument panel allows you to monitor coolant temperature. In addition, the high engine temperature indicator (16) on the lighted indicator display (17) illuminates when the coolant temperature exceeds 230°F (110°C). When the personnel heater is in use, warm coolant is used to heat the air in the cab before being returned to the radiator. Otherwise, coolant is returned directly to the radiator to be cooled. {77}------------------------------------------------ ### 1-18. ELECTRICAL SYSTEM ![](_page_77_Figure_2.jpeg) Figure 1-13. Electrical System The vehicle Electrical System is a combined 12/24 vdc system. Four 12-volt batteries (1, Figure 1-13) are connected in series-parallel with the negative terminal grounded to the vehicle chassis. (1) Positioning the master power switch (2) to on applies power to all electrical circuits needed to operate the vehicle. (2) The starting motor (3) operates directly from the 24 vdc source through the starter pushbutton (4). (3) A 12/24-volt belt-driven alternator (5) with a 100 amp capacity maintains the charge on the batteries. The 24 vdc source supplies electrical power to operate the starting motor, CTIS, fuel/water separator, air dryer, ether injection system, instrument panel gages, and windshield wipers/ washer. The 12 vdc source supplies electrical power to the vehicle lights and instrument panel lights. (4) The radiator fan off switch (6) is used to keep the radiator fan from engaging. The fan off indicator (7) will illuminate on the lighted indicator display (8) when the radiator fan is disabled. {78}------------------------------------------------ ![](_page_78_Picture_1.jpeg) Figure 1-13. Electrical System (Cont) (5) The ether start switch (9) is used to start the engine when the outside temperature is 32°F (0°C) or below. Pressing the ether start switch sends a measured charge of ether to the engine to make starting easier. (6) The warning light switch (10) operates the amber warning light on the cab roof when installed. (7) Positioning the hazard lights switch (11) to on causes both left and right turn signals to flash. {79}------------------------------------------------ ![](_page_79_Figure_1.jpeg) Figure 1-13. Electrical System (Cont) (8) A dimmer switch (12) is provided so that you can adjust the brightness of the instrument panel lighting. (9) The main light switch (13) is the only switch that is active even when the master power switch is off. a. Positioning the main selector lever to SER DRIVE causes the headlights, taillights, marker lights, and clearance lights to illuminate; stoplights will illuminate when brake pedal is depressed. b. Positioning the main selector lever to STOP LIGHT extinguishes all vehicle lights but allows stoplights to illuminate when brake pedal is depressed. c. Positioning the auxiliary lever to PARK with the main selector lever in SER DRIVE causes the headlights to extinguish and the front parking lights to illuminate. d. Positioning the main selector lever to BO MARKER causes the blackout marker lights to illuminate. e. Positioning the main selector lever to BO DRIVE causes the blackout drive light and blackout marker lights to illuminate. f. Instrument panel lights are illuminated when the main selector lever is in BRT position. {80}------------------------------------------------ ![](_page_80_Picture_1.jpeg) Figure 1-13. Electrical System (Cont) (10) Headlight high beams are controlled from the turn signal stalk (14). a. Pulling the turn signal stalk towards you will switch the headlights from low beam to high beam. The high beam indicator (15) will illuminate when your high beams are on. b. Pulling the turn signal stalk again will switch the headlights from high beam to low beam. (11) The VOLTS gage (16) shows the voltage output for the 24 vdc system. {81}------------------------------------------------ ### 1-18. ELECTRICAL SYSTEM (CONT) ![](_page_81_Figure_2.jpeg) 1A18A051 Figure 1-13. Electrical System (Cont) (12) The start inhibit pushbutton (17) removes power from the fuel shutoff solenoid. When the master power switch is positioned to on and the start inhibit pushbutton is pressed, the engine will crank but will not start until the master power switch has been turned off and then turned back on again. The start inhibit pushbutton is to be used to assist with troubleshooting only. It is not intended to be used during maintenance. (13) All electrical circuits are protected against overloads by circuit breakers (18). (14) Wiring harnesses and electrical cable assemblies carry electrical current to operate equipment and accessories. Most electrical equipment and accessories are grounded directly to the vehicle chassis. {82}------------------------------------------------ ### 1-19. BRAKE SYSTEM ![](_page_82_Figure_2.jpeg) Figure 1-14. Brake System The vehicle is equipped with a brake system which complies with the Federal Motor Vehicle Safety Standard (FMVSS) 121. The brake system is made up of an air compressor, air dryer, primary and secondary air tanks, and several valves which control the application and release of the brakes. (1) The air compressor (1, Figure 1-14) supplies approximately 120 psi (827 kPa) to the air dryer (2). (2) The air dryer contains a heating element and a desiccant cartridge to remove moisture from the air before it is delivered to the primary air tank (3) and secondary air tank (4). (3) The foot control valve (5) receives pressurized air from both the primary and secondary air tanks. The foot control valve is a two circuit design, with one set of ports directing air to the front brakes from the secondary air tank and a second set of ports directing air to the rear brakes from the primary air tank. The plumbing between the primary and secondary air tanks is designed to allow controlled braking in the event of a failure in either the primary (rear brakes) or secondary (front brakes) brake circuit. When air pressure in the wet tank (6) falls below a preset limit, pres-surized air, normally used for the CTIS, is redirected to the primary brake circuit. {83}------------------------------------------------ ## 1-19. BRAKE SYSTEM (CONT) ![](_page_83_Picture_2.jpeg) ![](_page_83_Figure_3.jpeg) (4) The SYSTEM PARK control (7) vents air pressure from the primary brake circuit and applies the rear spring brakes. (5) The TRAILER AIR SUPPLY control (8) supplies brake air pressure to a towed vehicle or trailer. (6) SERVICE gladhand (9) and EMERGENCY gladhand (10) provide the necessary connections to supply a towed vehicle or trailer with brake air pressure. {84}------------------------------------------------ ## 1-20. 11K SELF-RECOVERY WINCH (SRW) ![](_page_84_Picture_2.jpeg) Figure 1-15. 11K Self-Recovery Winch (SRW) a. 11K Self-Recovery Winch (SRW). When specified, any vehicle may be equipped with a 11K SRW (1) (Figure 1-15) mounted on the right hand frame rail. The 11K SRW is rated for 11,000 lbs (48,924 N) pull when the winch drum has one full layer of cable. Pulling capacity is reduced with each layer of cable added to the winch drum. One full layer of cable is the minimum amount of cable that may be left on the drum when using the 11K SRW. Pulling capacity with seven full layers of cable on the winch drum is 6,780 lbs (30,157 N). For recovery operations, the cable may be routed to the front or to the rear on all vehicles so equipped. (1) Hydraulic pressure to operate the 11K SRW is supplied by a single stage hydraulic pump (2) mounted on the back of the PTO (3). (2) Placing the PTO switch (4) in the on position causes the PTO drive gear to engage with the transmission. When the PTO is engaged, it drives the hydraulic pump. {85}------------------------------------------------ ## \| 1-20. 11K SELF-RECOVERY WINCH (SRW) (CONT) ![](_page_85_Figure_2.jpeg) Figure 1-15. 11K Self-Recovery Winch (SRW) (Cont) b. Hydraulic Reservoir. The hydraulic reservoir (5) is mounted on the left hand frame rail and contains the oil needed to operate the 11K SRW. The hydraulic reservoir holds 27 gal (102 L) of oil and is equipped with an oil gage (6). A fluid filter (7) is also mounted on the hydraulic reservoir to remove contaminates. ![](_page_85_Picture_5.jpeg) Figure 1-15. 11K Self-Recovery Winch (SRW) (Cont) (1) When the winch switch (8) is turned on, hydraulic power is supplied to the 11K SRW and the transmission is locked in neutral. (2) The cable can be payed out or reeled in by pressing the WINCH IN/OUT switch (9). {86}------------------------------------------------ ### 1-21. AIR SYSTEM ![](_page_86_Figure_2.jpeg) Figure 1-16. Air System The Air System provides clean, dry air for use in the air brake system and the CTIS. (1) The air system is pressurized by an engine driven air compressor (1, Figure 1-16) with an average output pressure of 125 psi (862 kPa). The system pressure is controlled by a pressure governor (2) which maintains the output pressure between 105-125 psi (724-862 kPa). (2) Air is supplied to the air brake portion of the system by the primary air tank (3) and secondary air tank (4). Air for the CTIS comes from the wet tank (5). {87}------------------------------------------------ ### 1-21. AIR SYSTEM (CONT) ![](_page_87_Figure_2.jpeg) Figure 1-16. Air System (Cont) (3) Air pressure in the tires is controlled by the CTIS ECU (6). The CTIS ECU provides for five tire pressure settings which are: highway, cross-country, sand, emergency, and run-flat. Kneeling valves (7) on the front tires allow the front of the vehicle to be lowered for internal air transport (C-130 and C-141). Air pressure is also used to keep the cab level through the use of air springs (8), mounted below the rear cab support, and a cab leveling valve (9). {88}------------------------------------------------ ## CHAPTER 2 OPERATING INSTRUCTIONS \| Section I.

Keep away from open fire and use in well-ventilated area. If adhesive, solvent, or sealing compound gets on skin or clothing, wash immediately with soap and water. Failure to comply may result in serious injury or death to personnel. a. Cleanliness. Dirt, grease, oil, and debris only get in the way and may cover up a serious problem. Use Dry Cleaning Solvent (Item 15, Appendix D) on metal surfaces where directed. b. Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, and missing, bent, or broken conditions. Look for chipped paint, bare metal, or rust around bolt heads. If any part seems loose, tighten it or notify Unit Maintenance. c. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If a bad weld is found, notify Unit Maintenance. d. Electrical Wires and Connections. Look for cracked or broken insulation, bare wires, and loose or broken connectors. Tighten loose connectors and make sure wires are in good shape. If a bad wire or connector is found, notify Unit Maintenance. {119}------------------------------------------------ ### 2-13. GENERAL MAINTENANCE INSTRUCTIONS (CONT) e. Hydraulic Lines and Fittings. Look for wear, damage, and leaks; make sure clamps and fittings are tight. Wet spots show leaks. A stain around a fitting or connector can mean a leak. If a leak comes fitting or connector, tighten it. If something is broken or worn out, notify Unit Maintenance. f. Damage. Damage is defined as any condition that affects safety or would make the vehicle unserviceable for mission requirements. ## 2-14. FLUID LEAKAGE It is necessary to know how fluid leakage affects the status of fuel, oil, coolant, and hydraulic systems. The following are definitions of the different types of leakage that can determine the status of the vehicle. Learn, then be familiar with them, and REMEMBER-WHEN IN DOUBT, NOTIFY UNIT MAINTENANCE! ## CAUTION - · Equipment operation is allowable with minor leakage (Class I or Class II). Fluid levels of items with Class I and Class II leaks must be checked often so proper levels can be kept. Consideration must be given to the fluid capacity in the item/system being checked/ inspected. Failure to comply may result in damage to equipment. - · Class III leaks must be reported to Unit Maintenance. Failure to comply may result in damage to equipment. Fluid leakage is classified and defined as follows: \| CLASSIFICATION \| IDENTIFICATION \| \|----------------\|--------------------------------------------------------------------------------------------------------------------\| \| Class I \| Seepage of fluid (indicated by wetness or discoloration)<br>not great enough to form drops. \| \| Class II \| Leakage of fluid great enough to form drops but not<br>enough to cause drops to drip from item being<br>inspected. \| \| Class III \| Leakage of fluid great enough to cause drops to drip<br>from item being checked. \| {120}------------------------------------------------ ### 2-15.

INTRODUCTION #### SCOPE B-1. This appendix lists components of the end item and basic issue items for the LMTV to help you inventory the items for safe and efficient operation of the equipment. #### B-2. GENERAL The Components of End Item (COEI) and Basic Issue Items (BII) lists are divided into the following sections: a. Section II, Components of End Item. This listing is for information purposes only, and is not authority to requisition replacements. These items are part of the LMTV, but they are not to be removed and separately packaged for transportation or shipment. As part of the end item, these items must be with the end item whenever it is issued or transferred between property accounts. Illustrations are furnished to help you find and identify the items. b. Section III. Basic Issue Items. These essential items are required to place the LMTV in operation, operate it, and to do emergency repairs. Although shipped separately packaged, BII must be with the LMTV during operation and when it is transferred between property accounts. Listing these items is your authority to request/requisition them for replacement based on authorization of the end item by the TOE/MTOE. Illustrations are furnished to help you find and identify the items. ### B-3. EXPLANATION OF COLUMNS The following provides an explanation of columns found in the tabular listings: a. Column (1), Illus Number. Gives you the number of the item illustrated. b. Column (2), National Stock Number. Identifies the stock number of the item to be used for requisitioning purposes. {751}------------------------------------------------ ### B-3. EXPLANATION OF COLUMNS (CONT) c. Column (3), Description and Usable On Code. Identifies the Federal item name (in capital letters) followed by a minimum description when needed. The last line below the description is the Commercial and Government Entity Code (CAGEC) (in parentheses) and the part number. If the item you need is not the same for different models of the equipment, a Usable On Code will appear on the right side of the description column on the same line as the part number. These codes are identified below: \| CODE \| USED ON \| \|------\|---------------------------------\| \| LAB \| M1078 \| \| LWB \| M1078 w/11K Self-Recovery Winch \| \| LAD \| M1079 \| \| LWD \| M1079 w/11K Self-Recovery Winch \| \| LAA \| M1080 \| \| LAC \| M1081 \| \| LWC \| M1081 w/11K Self-Recovery Winch \| d.

Carbon monoxide is a colorless, odorless, DEADLY POISONOUS gas and when breathed deprives body of oxygen and causes SUFFOCATION. Breathing air with carbon monoxide produces symptoms of headache, dizziness, loss of muscular control, a sleepy feeling, and coma. Permanent BRAIN DAMAGE or DEATH can result from severe exposure. The following precautions MUST be followed to ensure personnel are safe whenever any type of personnel heater or engine is operated for any purpose. Failure to comply may result in serious injury or death to personnel. DO NOT operate heater or engine in an enclosed area without adequate ventilation. DO NOT drive any vehicle with inspection plates, cover plates, or engine compartment covers removed unless necessary for maintenance purposes. NEVER sleep in a vehicle when heater is operating or the engine is idling. BE ALERT at all times during vehicle operation for exhaust odors and exposure symptoms. If either is present, IMMEDIATELY VENTILATE personnel compartments. Treatment of affected personnel shall be: exposure to fresh air; keep warm; DO NOT PERMIT PHYSICAL EXERCISE. If necessary, give cardiopulmonary resuscitation, as described in FM 21-11, and get immediate medical attention. Failure to comply may result in serious injury or death to personnel. THE BEST DEFENSE AGAINST CARBON MONOXIDE POISONING IS GOOD VENTII ATION. WARNING CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU. DO NOT operate engine in an enclosed area without adequate ventilation.

MAINTENANCE FORMS AND PROCEDURES Department of the Army forms and procedures used for equipment maintenance will be those prescribed by DA Pam 738-750 as contained in the Maintenance Management Update. # 1-3. CORROSION PREVENTION AND CONTROL (CPC) The vehicle has a total service life of 20 years which allows for extended periods of operation in a corrosive environment. A corrosive environment includes exposure to high humidity, salt spray, road de-icing chemicals, gravel damage, and atmospheric contamination. No action beyond normal washing and repair of damaged areas is needed to control corrosion. To prevent moisture accumulation, drain holes are provided on structural and sheet metal areas where needed, and stowage boxes are provided with seals and baffled drains. Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any corrosion problems with the vehicle be reported so that the problem can be corrected and improvements made to prevent the problem in the future. While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem. If a corrosion problem is identified, it can be reported using form SF 368 (Product Quality Deficiency Report). Using keywords such as "corrosion", "rust", "cracking", or "deterioration" will ensure that the information is identified as a CPC problem. Form SF 368 should be submitted to the address specified in DA PAM 738-750. ### 1-4. DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE Command decision, according to the tactical situation, will determine when the using organization is to destroy a vehicle. A destruction plan will be prepared by the using organization, unless one was prepared by a higher authority. For general vehicle destruction procedures, refer to TM 750-244-6, Procedures for Destruction of Tank-Automotive Equipment to Prevent Enemy Use (U.S. Army Tank-automotive and Artillery Command). {45}------------------------------------------------ ## 1-5.

Vehicle Classification {68}------------------------------------------------ ## Section III. PRINCIPLES OF OPERATION 1-14. Powertrain ![](_page_68_Picture_3.jpeg) Figure 1-9. Powertrain The Powertrain for the vehicle is provided by a diesel engine (1, Figure 1-9) which is coupled directly to an automatic transmission (2). Power from the automatic trans-mission is supplied to the transfer case (3) and on to the front steering axle (4) and rear drive axle (5) through a series of drive shafts and universal joints. The capability of the powertrain is enhanced by the use of an seven-speed transmission. a. Engine. The vehicle is equipped with a Caterpillar model 3116 ATAAC diesel engine (1, Figure 1-9), rated at 225 hp (168 kW). {69}------------------------------------------------ ## 1-14. POWERTRAIN (CONT) ![](_page_69_Figure_2.jpeg) Figure 1-9. Powertrain (Cont) b. Transmission. The vehicle is equipped with a fully automatic, electronically controlled, seven-speed close-ratio Allison transmission Model MD3070PT (2, Figure 1-9). The WTEC II Transmission ECU Pushbutton Shift Selector (TEPSS) has a velcro cover and the WTEC III Transmission Pushbutton Shift Selector (TPSS) does not have a velcro cover. (1) The WTEC II TEPSS (7) or WTEC III TPSS (7) is located in the instrument panel, to the Operator's left. (2) The transmission defaults to Neutral (N) whenever electrical power is removed from the vehicle. When electrical power is first supplied to the vehicle, the WTEC II TEPSS or WTEC III TPSS will momentarily display MODE ON in the LED display. MODE ON display will disappear and N will be left in the LED display. This lets you know that the transmission is in highway mode and Neutral range (N), (3) The Drive (D) gear selection is used for normal driving conditions. The transmission will engage 2nd gear when D is selected and the vehicle is stopped. The LED display will illuminate 7 2, indicating that the transmission is in 2nd gear and there are seven forward gears available. Low gear (1st gear), is available only through manual selection by pressing the down arrow button until 1 1 is displayed in the LED display. You may manually downshift or upshift to a lower or higher gear range as required. However, the transmission will not downshift to a lower gear if the engine speed is too high for the gear selected. Selecting a specific gear; for example, 3rd; will prevent the transmission upshifting past the selected gear. {70}------------------------------------------------ ![](_page_70_Figure_1.jpeg) Figure 1-9. Powertrain (Cont) (4) When the MODE button is pressed, MODE ON will illuminate in the LED display. If the vehicle is stopped; the LED display will illuminate 5 MODE ON 2, indicating that the transmission is in 2nd gear and there are five forward gears available. This off-road mode is useful if road or load conditions require the use of a lower gear range for maximum torque. The vehicle must be completely stopped and engine operating at idle speed before the transmission will allow you to shift from a forward gear to Reverse (R) gear. (5) The transmission may include an electrically controlled PTO (8). The PTO provides power to a hydraulic pump, which powers the 11K Self-Recovery Winch (SRW) (if equipped). The transmission will not shift from Neutral (N) if the PTO is engaged and the winch switch is in the on position. c. Transfer Case. The transfer case (3) contains the gears and clutches that provide the transmission (2) with the seventh gear. The transfer case delivers power from the transmission to the front driveshaft and rear driveshaft. In normal driving conditions, the transfer case splits the output torque of the transmission, providing 70 percent of the torque to the rear and 30 percent to the front. In 1st gear, or any time MODE ON is illuminated in LED display, the output torque of the transmission is split evenly between front and rear. {71}------------------------------------------------ ### 1-15. ENGINE AIR INTAKE SYSTEM ![](_page_71_Picture_2.jpeg) Figure 1-10. Engine Air Intake System The Engine Air Intake System consists of a dry-type intake air cleaner (1, Figure 1-10), turbocharger (2), and a Charge Air Cooler (CAC) (3). The turbocharger increases engine horsepower by delivering a higher volume of air to the engine. The turbocharger compresses the air and delivers it to the CAC. The air flows through the CAC which cools the air before it is delivered to the engine cylinders. The air aspiration tubes (4) pass the cooled and compressed air to the engine inlet manifold (5). The compressed air/fuel mixture allows more complete burning of the fuel. The result is an increase in horsepower and lower emissions. {72}------------------------------------------------ ### 1-16. FUEL SYSTEM ![](_page_72_Figure_2.jpeg) Figure 1-11. Fuel System The Fuel System consists of a 56 gal (212 L) capacity, 54 gal (204 L) useable fuel tank ■ (1, Figure 1-11), fuel priming pump and fuel/water separator (2), fuel shutoff solenoid (3), fuel governor (4), and secondary fuel filter (5). (1) The fuel priming pump is hand actuated and is used to pump fuel to the fuel governor after maintenance is performed on certain parts of the fuel system. (2) The fuel/water separator removes water and large solid particles from the fuel before it is passed to the fuel governor. (3) The fuel governor responds to input from the accelerator pedal and causes an increase or decrease in engine speed. The fuel governor adjusts the amount of fuel delivered to the engine as engine speed changes. {73}------------------------------------------------ ## 1-16. FUEL SYSTEM (CONT) ![](_page_73_Picture_2.jpeg) Figure 1-11. Fuel System (Cont) (4) The secondary fuel filter removes finer particles from the fuel before it reaches the cylinder head. (5) The vehicle is also equipped with an ether quick start system for starting the engine when the outside temperature is below 32°F (0°C). The ether quick start system is composed of an ether cylinder (6), ether valve (7), two ether nozzles (8), and an ether sensor switch (9). The ether sensor switch detects the temperature of the engine coolant and disables the ether valve if the coolant temperature is above 100°F (38°C). {74}------------------------------------------------ ![](_page_74_Figure_1.jpeg) Figure 1-12. Cooling System The Cooling System protects the engine, transmission, and air compressor by providing a means of removing the heat generated during operation of the vehicle. (1) The radiator pressure cap (1, Figure 1-12), in combination with the ethylene glycolbased antifreeze, effectively raises the boiling point of the coolant to well above 212°F (100°C). (2) The thermostat (2) helps the engine to warm up quickly by remaining closed until the coolant temperature reaches approximately 199°F (93°C). When the coolant temperature reaches approximately 199°F (93°C), the thermostat opens and coolant is circulated through the water jacket in the engine to maintain the correct operating temperature for the engine. Coolant is drawn from the radiator (3), through the transmission oil cooler (4), and circulated through the cooling system by the water pump (5). Heat is drawn from the radiator by the engine fan pulling air over the radiator cooling fins. (3) A radiator overflow tank (6) is provided to allow for expansion of the coolant. The radiator overflow tank also serves as the point where new coolant is introduced into the cooling system. The radiator overflow tank has two sight glasses; the upper sight glass (7) indicates the level to fill to with engine shut down. If coolant is not visible in the lower sight glass (8), do not operate the vehicle. {75}------------------------------------------------ ## 1-17. COOLING SYSTEM (CONT) ![](_page_75_Picture_2.jpeg) Figure 1-12. Cooling System (Cont) (4) The engine fan (9), with pneumatic fan clutch (10), is activated by the water temperature sensor (11). Whenever this sensor detects a high engine temperature condition, air pressure is removed from the fan clutch and the engine fan is engaged. (5) Positioning the radiator fan off switch (12) to the on position keeps the engine fan from engaging. {76}------------------------------------------------ ![](_page_76_Figure_1.jpeg) Figure 1-12. Cooling System (Cont) (6) The WATER TEMP gage (15) on the instrument panel allows you to monitor coolant temperature. In addition, the high engine temperature indicator (16) on the lighted indicator display (17) illuminates when the coolant temperature exceeds 230°F (110°C). When the personnel heater is in use, warm coolant is used to heat the air in the cab before being returned to the radiator. Otherwise, coolant is returned directly to the radiator to be cooled. {77}------------------------------------------------ ### 1-18. ELECTRICAL SYSTEM ![](_page_77_Figure_2.jpeg) Figure 1-13. Electrical System The vehicle Electrical System is a combined 12/24 vdc system. Four 12-volt batteries (1, Figure 1-13) are connected in series-parallel with the negative terminal grounded to the vehicle chassis. (1) Positioning the master power switch (2) to on applies power to all electrical circuits needed to operate the vehicle. (2) The starting motor (3) operates directly from the 24 vdc source through the starter pushbutton (4). (3) A 12/24-volt belt-driven alternator (5) with a 100 amp capacity maintains the charge on the batteries. The 24 vdc source supplies electrical power to operate the starting motor, CTIS, fuel/water separator, air dryer, ether injection system, instrument panel gages, and windshield wipers/ washer. The 12 vdc source supplies electrical power to the vehicle lights and instrument panel lights. (4) The radiator fan off switch (6) is used to keep the radiator fan from engaging. The fan off indicator (7) will illuminate on the lighted indicator display (8) when the radiator fan is disabled. {78}------------------------------------------------ ![](_page_78_Picture_1.jpeg) Figure 1-13. Electrical System (Cont) (5) The ether start switch (9) is used to start the engine when the outside temperature is 32°F (0°C) or below. Pressing the ether start switch sends a measured charge of ether to the engine to make starting easier. (6) The warning light switch (10) operates the amber warning light on the cab roof when installed. (7) Positioning the hazard lights switch (11) to on causes both left and right turn signals to flash. {79}------------------------------------------------ ![](_page_79_Figure_1.jpeg) Figure 1-13. Electrical System (Cont) (8) A dimmer switch (12) is provided so that you can adjust the brightness of the instrument panel lighting. (9) The main light switch (13) is the only switch that is active even when the master power switch is off. a. Positioning the main selector lever to SER DRIVE causes the headlights, taillights, marker lights, and clearance lights to illuminate; stoplights will illuminate when brake pedal is depressed. b. Positioning the main selector lever to STOP LIGHT extinguishes all vehicle lights but allows stoplights to illuminate when brake pedal is depressed. c. Positioning the auxiliary lever to PARK with the main selector lever in SER DRIVE causes the headlights to extinguish and the front parking lights to illuminate. d. Positioning the main selector lever to BO MARKER causes the blackout marker lights to illuminate. e. Positioning the main selector lever to BO DRIVE causes the blackout drive light and blackout marker lights to illuminate. f. Instrument panel lights are illuminated when the main selector lever is in BRT position. {80}------------------------------------------------ ![](_page_80_Picture_1.jpeg) Figure 1-13. Electrical System (Cont) (10) Headlight high beams are controlled from the turn signal stalk (14). a. Pulling the turn signal stalk towards you will switch the headlights from low beam to high beam. The high beam indicator (15) will illuminate when your high beams are on. b. Pulling the turn signal stalk again will switch the headlights from high beam to low beam. (11) The VOLTS gage (16) shows the voltage output for the 24 vdc system. {81}------------------------------------------------ ### 1-18. ELECTRICAL SYSTEM (CONT) ![](_page_81_Figure_2.jpeg) 1A18A051 Figure 1-13. Electrical System (Cont) (12) The start inhibit pushbutton (17) removes power from the fuel shutoff solenoid. When the master power switch is positioned to on and the start inhibit pushbutton is pressed, the engine will crank but will not start until the master power switch has been turned off and then turned back on again. The start inhibit pushbutton is to be used to assist with troubleshooting only. It is not intended to be used during maintenance. (13) All electrical circuits are protected against overloads by circuit breakers (18). (14) Wiring harnesses and electrical cable assemblies carry electrical current to operate equipment and accessories. Most electrical equipment and accessories are grounded directly to the vehicle chassis. {82}------------------------------------------------ ### 1-19. BRAKE SYSTEM ![](_page_82_Figure_2.jpeg) Figure 1-14. Brake System The vehicle is equipped with a brake system which complies with the Federal Motor Vehicle Safety Standard (FMVSS) 121. The brake system is made up of an air compressor, air dryer, primary and secondary air tanks, and several valves which control the application and release of the brakes. (1) The air compressor (1, Figure 1-14) supplies approximately 120 psi (827 kPa) to the air dryer (2). (2) The air dryer contains a heating element and a desiccant cartridge to remove moisture from the air before it is delivered to the primary air tank (3) and secondary air tank (4). (3) The foot control valve (5) receives pressurized air from both the primary and secondary air tanks. The foot control valve is a two circuit design, with one set of ports directing air to the front brakes from the secondary air tank and a second set of ports directing air to the rear brakes from the primary air tank. The plumbing between the primary and secondary air tanks is designed to allow controlled braking in the event of a failure in either the primary (rear brakes) or secondary (front brakes) brake circuit. When air pressure in the wet tank (6) falls below a preset limit, pres-surized air, normally used for the CTIS, is redirected to the primary brake circuit. {83}------------------------------------------------ ## 1-19. BRAKE SYSTEM (CONT) ![](_page_83_Picture_2.jpeg) ![](_page_83_Figure_3.jpeg) (4) The SYSTEM PARK control (7) vents air pressure from the primary brake circuit and applies the rear spring brakes. (5) The TRAILER AIR SUPPLY control (8) supplies brake air pressure to a towed vehicle or trailer. (6) SERVICE gladhand (9) and EMERGENCY gladhand (10) provide the necessary connections to supply a towed vehicle or trailer with brake air pressure. {84}------------------------------------------------ ## 1-20. 11K SELF-RECOVERY WINCH (SRW) ![](_page_84_Picture_2.jpeg) Figure 1-15. 11K Self-Recovery Winch (SRW) a. 11K Self-Recovery Winch (SRW). When specified, any vehicle may be equipped with a 11K SRW (1) (Figure 1-15) mounted on the right hand frame rail. The 11K SRW is rated for 11,000 lbs (48,924 N) pull when the winch drum has one full layer of cable. Pulling capacity is reduced with each layer of cable added to the winch drum. One full layer of cable is the minimum amount of cable that may be left on the drum when using the 11K SRW. Pulling capacity with seven full layers of cable on the winch drum is 6,780 lbs (30,157 N). For recovery operations, the cable may be routed to the front or to the rear on all vehicles so equipped. (1) Hydraulic pressure to operate the 11K SRW is supplied by a single stage hydraulic pump (2) mounted on the back of the PTO (3). (2) Placing the PTO switch (4) in the on position causes the PTO drive gear to engage with the transmission. When the PTO is engaged, it drives the hydraulic pump. {85}------------------------------------------------ ## | 1-20. 11K SELF-RECOVERY WINCH (SRW) (CONT) ![](_page_85_Figure_2.jpeg) Figure 1-15. 11K Self-Recovery Winch (SRW) (Cont) b. Hydraulic Reservoir. The hydraulic reservoir (5) is mounted on the left hand frame rail and contains the oil needed to operate the 11K SRW. The hydraulic reservoir holds 27 gal (102 L) of oil and is equipped with an oil gage (6). A fluid filter (7) is also mounted on the hydraulic reservoir to remove contaminates. ![](_page_85_Picture_5.jpeg) Figure 1-15. 11K Self-Recovery Winch (SRW) (Cont) (1) When the winch switch (8) is turned on, hydraulic power is supplied to the 11K SRW and the transmission is locked in neutral. (2) The cable can be payed out or reeled in by pressing the WINCH IN/OUT switch (9). {86}------------------------------------------------ ### 1-21. AIR SYSTEM ![](_page_86_Figure_2.jpeg) Figure 1-16. Air System The Air System provides clean, dry air for use in the air brake system and the CTIS. (1) The air system is pressurized by an engine driven air compressor (1, Figure 1-16) with an average output pressure of 125 psi (862 kPa). The system pressure is controlled by a pressure governor (2) which maintains the output pressure between 105-125 psi (724-862 kPa). (2) Air is supplied to the air brake portion of the system by the primary air tank (3) and secondary air tank (4). Air for the CTIS comes from the wet tank (5). {87}------------------------------------------------ ### 1-21. AIR SYSTEM (CONT) ![](_page_87_Figure_2.jpeg) Figure 1-16. Air System (Cont) (3) Air pressure in the tires is controlled by the CTIS ECU (6). The CTIS ECU provides for five tire pressure settings which are: highway, cross-country, sand, emergency, and run-flat. Kneeling valves (7) on the front tires allow the front of the vehicle to be lowered for internal air transport (C-130 and C-141). Air pressure is also used to keep the cab level through the use of air springs (8), mounted below the rear cab support, and a cab leveling valve (9). {88}------------------------------------------------ ## CHAPTER 2 OPERATING INSTRUCTIONS | Section I.

If a bad weld is found, notify Unit Maintenance. d. Electrical Wires and Connections. Look for cracked or broken insulation, bare wires, and loose or broken connectors. Tighten loose connectors and make sure wires are in good shape. If a bad wire or connector is found, notify Unit Maintenance. {119}------------------------------------------------ ### 2-13. GENERAL MAINTENANCE INSTRUCTIONS (CONT) e. Hydraulic Lines and Fittings. Look for wear, damage, and leaks; make sure clamps and fittings are tight. Wet spots show leaks. A stain around a fitting or connector can mean a leak. If a leak comes fitting or connector, tighten it. If something is broken or worn out, notify Unit Maintenance. f. Damage. Damage is defined as any condition that affects safety or would make the vehicle unserviceable for mission requirements. ## 2-14. FLUID LEAKAGE It is necessary to know how fluid leakage affects the status of fuel, oil, coolant, and hydraulic systems. The following are definitions of the different types of leakage that can determine the status of the vehicle. Learn, then be familiar with them, and REMEMBER-WHEN IN DOUBT, NOTIFY UNIT MAINTENANCE! ## CAUTION - · Equipment operation is allowable with minor leakage (Class I or Class II). Fluid levels of items with Class I and Class II leaks must be checked often so proper levels can be kept. Consideration must be given to the fluid capacity in the item/system being checked/ inspected. Failure to comply may result in damage to equipment. - · Class III leaks must be reported to Unit Maintenance. Failure to comply may result in damage to equipment. Fluid leakage is classified and defined as follows: | CLASSIFICATION | IDENTIFICATION | |----------------|--------------------------------------------------------------------------------------------------------------------| | Class I | Seepage of fluid (indicated by wetness or discoloration) not great enough to form drops. | | Class II | Leakage of fluid great enough to form drops but not enough to cause drops to drip from item being inspected. | | Class III | Leakage of fluid great enough to cause drops to drip from item being checked. | {120}------------------------------------------------ ### 2-15.

INTRODUCTION ### F-1. GENERAL This appendix gives lubrication/service requirements for the vehicle which are the responsibility of the Operator/Crew. a. Adherence. Intervals (on-condition or hard time) and the related man-hour times are based on normal operation. The man-hour time specified is the time needed to do all the services prescribed for a particular interval. On-condition (OC) oil sample intervals shall be applied unless changed by the Army Oil Analysis Program (AOAP) laboratory. Change the hard time interval if lubricants are contaminated or if operating the equipment under adverse operating conditions, including longer-than-usual operating hours. The calendar interval may be extended during periods of low activity. If extended, adequate preservation precautions must be taken. Hard time intervals will be applied in the event AOAP laboratory support is not available. Hard time intervals must be applied during the warranty period. Intervals shown in this lubrication order and services are based on mileage/calendar times. The lubrication/services for the vehicle is to be performed at whichever interval occurs first. #### WARNING - · Dry Cleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles and gloves; use only in well-ventilated area; avoid contact with skin, eyes, and clothes, and do not breath vapors. Keep away from heat or flame. Never smoke when using solvent; the flashpoint for Type I Dry Cleaning Solvent is 100°F (38°C) and for Type II is 138°F (50°C). Failure to comply may result in serious injury or death to personnel. - · If personnel become dizzy while using cleaning solvent, immediately get fresh air and medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts eyes, immediately flush eyes with water and get medical attention. Failure to comply may result in serious injury or death to personnel. - b. Cleaning Fittings Before Lubrication. Clean parts with Dry Cleaning Solvent (SD P-D-680) or equivalent. Dry before lubricating. Dashed arrows indicate lubrication on both sides of the equipment. - c. Lubrication After Fording. If a fording operation occurs, lubricate all fittings below fording depth and check submerged gear boxes for presence of water. {779}------------------------------------------------ ## F-1. GENERAL (CONT) - d. Lubrication After High-Pressure Washing. After a thorough washing, lubricate all grease fittings and oil can points outside and underneath vehicle. - e. Lubrication Local Views. A reference to the appropriate local view is given after most lubrication/service entries. Local views begin on page F-7. ## F-2. CORROSION CONTROL Refer to para 1-3 for appropriate corrosion control procedures. ## F-3. AOAP SAMPLING INTERVAL Engine/transmission oil must be sampled every 90 days as prescribed by DA Pam 738-750. Hydraulic fluids must be sampled annually as prescribed by DA Pam 738-750. ### F-4.

LUBRICATION/SERVICE NOTES #### WARNING Engine dipstick is located close to starter solenoid connectors which contain 24 vdc and high amperage. Use caution removing/installing engine dipstick to prevent shorting across starter solenoids when checking engine oil level. Failure to comply may result in serious injury or death to personnel or damage to equipment. - 1. Check engine oil level daily. Oil is full when level is within crosshatch marks on dipstick. Do not overfill. Fill crankcase with OE/HDO specified for the ambient temperature. - 2. Check transmission/transfer case oil level daily with vehicle parked on level surface and transmission range selector in Neutral (N). Safe operating oil level is when transmission/transfer case fluid level is halfway between "HOT ADD" line and "HOT FULL" line on dipstick. With engine at idle (500-800 rpm) for one minute and engine coolant temperature at normal operating range (165-180°F (74-82°C)), check transmission/transfer case oil level. If level is below "HOT ADD" line, add one (1) quart of oil and check oil level. Repeat this procedure until oil level is halfway between "HOT ADD" line and "HOT FULL" line.

Was brought to you by me: ![](_page_836_Picture_2.jpeg) # Liberated Manuals -- free army and government manuals Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap "watermarks" and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends? I am setting this document FREE. This document was made by the US Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on. I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines: <A HREF=http://www.liberatedmanuals.com/>Free Military and Government Manuals</A> Sincerely lgor Chudov http://igor.chudov.com/
