Description

M1078 Series LMTV Operator’s Instructions Manual – TM 9-2320-365-10

This is the complete Operator’s Instructions Manual for the M1078 Series, 2-1/2 Ton, 4×4, Light Medium Tactical Vehicles (LMTV). Published under document number TM 9-2320-365-10 and Air Force T.O. 36A12-1B-1095-1, dated 17 June 1998, this field manual gives operators and crew members everything they need to safely operate, inspect, and maintain all four LMTV variants: the M1078 cargo truck, the M1079 van, the M1080 chassis truck, and the M1081 air drop cargo truck. At 781 pages, the coverage is thorough – from the instrument panel layout to the 11K Self-Recovery Winch, from cold-weather starting to fording procedures.

The M1078 Series LMTV Operator’s Instructions Manual is structured around the way an operator actually uses the vehicle. Chapter 2 walks through every control and indicator before moving into PMCS – the before, during, after, weekly, and monthly checks that keep the truck mission-capable. Chapter 3 then gives troubleshooting trees for virtually every system on the vehicle and operator-level maintenance procedures that can be performed in the field. Throughout, the manual cross-references the warning summaries and lubrication guides so the operator has the correct specifications on hand.

Vehicle Systems Covered in Depth

The manual documents the Caterpillar 3116 ATAAC turbocharged diesel engine (403 cid / 6.6 L, 225 hp) and the Allison MD3070PT seven-speed automatic transmission with integral transfer case. The Central Tire Inflation System (CTIS) gets its own operating section, as does the 11K Self-Recovery Winch with its hydraulic pump and PTO. The air brake system, air system, cooling system, fuel system, and electrical system (12/24 VDC with four 6TL batteries) are all covered in the Principles of Operation chapter and again in the troubleshooting tables.

Model-specific content is separated where it matters: the M1079 Van has its own PMCS table and dedicated sections for AC power connection, 12/24 VDC power, interior lighting, fan operation, field phone binding posts, and air conditioner/heater operation. The M1081 Air Drop gets its own PMCS table plus preparation and recovery procedures for air drop operations. Cargo bed side panel stowage, cargo cover kit installation, and troopseat kit operation are covered for the cargo variants.

Warnings are collected in a summary at the front and repeated at point of use – carbon monoxide, NBC contamination, hydraulic fluid toxicity, battery gas, air pressure limits, tire handling, and cab raising/lowering. The lubrication appendix lists every fluid type, capacity, and temperature range for the engine, transmission, steering, hydraulic reservoir, cooling system, and air/hydraulic power unit, with a lubrication locator view and detailed notes on each point.

What This Manual Enables You to Do

With the M1078 Series LMTV Operator’s Instructions Manual on hand, you can perform the full range of operator-level tasks the Army expects of an LMTV crew member:

• Identify and operate every control, switch, gage, and indicator on the instrument panel, auxiliary panel, center console, steering column, and exterior
• Run complete before, during, after, weekly, and monthly PMCS using the model-specific tables
• Start the engine in cold weather using the ether quick-start system and rapid engine warm-up procedure
• Operate the CTIS in highway, cross-country, sand, emergency, and run-flat modes
• Raise and lower the cab, spare tire, and suspension using the hydraulic manifold and back-up pump
• Operate the 11K Self-Recovery Winch for vehicle recovery in both front and rear directions
• Set up and operate the Light Material Handling Crane (LMHC)
• Connect a towbar, tow a disabled vehicle, and cage rear spring brakes
• Change a tire, service tires manually, and stow the spare
• Perform emergency procedures for loss of air pressure and starting a disabled vehicle
• Troubleshoot engine, transmission, brake, air, electrical, CTIS, steering, and hydraulic problems using the malfunction index and troubleshooting tables
• Prepare the vehicle for shipment, internal air transport, and air drop
• Lubricate the vehicle correctly with the right fluid for the ambient temperature

The value of using the correct procedures cannot be overstated. The LMTV’s air brake system, CTIS, and hydraulic systems all have specific pressure limits, torque values, and operating restrictions that, if ignored, can cause equipment damage or injury. This manual gives you those numbers directly from the source – for example, the 415-475 lb-ft lugnut torque, the 65 psi minimum brake air pressure, the 55/33/20/14 psi CTIS settings, and the 11,000 lb winch capacity at the bottom cable layer.
