Fmtv Technical Manual | 1080p 360p |

Before loading an FMTV onto a lowboy trailer, consult Appendix A. The manual lists the exact curb weight, height with the cab tilted, and center of gravity. Ignoring this leads to DOT fines or rollovers.

The Central Tire Inflation System is the FMTV’s most finicky subsystem. The manual’s “Pressure Vs. Time” chart tells you exactly how long the system should take to air up from “Highway” to “Cross-Country” mode.

| Feature | Description | |---------|-------------| | Safety Warnings | Bolded, highlighted boxes: "WARNING – High pressure air/hydraulic" | | Lubrication Order (LO) | NATO multi-purpose grease, engine oil (15W-40 MIL-PRF-2104), coolant (OAT) | | Torque Specifications | Wheel lug nuts (450–500 ft-lbs), cylinder head bolts (stage torquing) | | Towing & Recovery | Emergency towing speed limits, lifting eyes, tiedown points | | Weight & Dimensions Table | Curb weight, GVWR (up to 56,000 lbs for M1083), length/width/height | | Fording Kit Procedure | Install exhaust extension, CTIS set to "Sand/Mud", electrical waterproofing | | Diagnostic Codes Appendix | Full list of SPN/FMI (Suspect Parameter Number / Failure Mode Identifier) |

In the modern Army, most mechanics access TMs via the EMM (Electronic Maintenance Manual) system or ETM (Electronic Technical Manuals) loaded onto rugged laptops (like the Panasonic Toughbook).

For the surplus owner or civilian mechanic, downloading PDF versions from official sources (like the Army Logistics University or public .mil domains) is the standard. However, nothing beats a printed, binder-ready manual when you are laying in the mud under a differential.

An FMTV is designed to be reliable, but only if it is maintained to standard. The Technical Manual is not just a suggestion; it is the standard. Whether you are a motor sergeant preparing for a layout or a civilian restoring an LMTV, investing the time to acquire and read the correct TM will save you thousands in parts and countless hours of frustration.
