Taken together, this M915 M916 M917 M918 M919 M920 Organizational Maintenance Manual walks a unit-level mechanic from initial receipt of the vehicle straight through troubleshooting, teardown, and reassembly of every major system on the truck, with the integrated Chapter 3 material applying across all six model variants before the individual system chapters go deeper on each assembly.

Engine, Drivetrain, and Chassis Data

All six variants of the M915 M916 M917 M918 M919 M920 family share the same Cummins NTC-400 six-cylinder, four-cycle turbocharged diesel (855 cu in / 14 liter displacement, 13.5:1 compression, 400 gross hp at 2,100 rpm, 1,150 lb-ft gross torque at 1,500 rpm) paired with a Caterpillar D7155 semi-automatic transmission offering 16 forward and 2 reverse speeds. The manual documents the Oshkosh transfer case fitted to M916 through M920, the Rockwell front and rear tandem axles used across the line (with different ratios and capacities for the M915 versus the M916/M917/M918/M919/M920 chassis types), and the model-specific front and rear suspension data. Chassis differences – Type I for the M915, Type II for the M916/M918, and Type III for the M917/M919/M920 – are broken out clearly so a technician working on any single truck in the family can go straight to the data that applies to that chassis.

Why Technicians Rely on This Manual

This M915 M916 M917 M918 M919 M920 Organizational Maintenance Manual gives a unit mechanic everything needed to diagnose and correct problems on the engine, transmission, transfer case, axles, brakes, steering, electrical system, winch, PTO, frame, body, and cab of these AM General 5-ton-class military trucks and chassis – from routine PMCS through full troubleshooting-to-repair sequences with correct torque values, capacities, and part-specific procedures. Working from the correct TM 9-2320-273-20 procedures and specifications, instead of guesswork or generic references, protects the driveline and keeps repairs within the tolerances the Army itself specified for this equipment. The manual downloads instantly as a PDF after purchase – no shipping, no waiting – and can be read on a phone, tablet, laptop, or shop computer, or printed out a page at a time for use next to the vehicle.
