What This Manual Covers on the Truck

The CUCV M1008/M1009/M1010/M1028/M1031 series shares a common 90-degree 379 cu in (6.2L) diesel V-8 producing 135 hp at 3600 rpm, paired with a GM Hydra-Matic 400 three-speed automatic transmission and a manually engaged transfer case for four-wheel drive. The manual documents the 12/24-volt electrical system, NATO slave cable receptacle, power-assisted front disc and rear drum brakes, and model-specific bodies — cargo bed, ambulance box, shelter carrier, and utility bed — with step-by-step removal, installation, and adjustment procedures illustrated alongside the text.

Troubleshooting and Technical Data

Chapter 2’s Troubleshooting Symptom Index organizes both mechanical and electrical fault symptoms by system, directing the technician straight to the correct repair procedure. Appendix E lists standard torque specifications by bolt grade and size, and Appendix F contains the full wiring diagrams and schematics needed for electrical fault-finding across the generating, starting, lighting, instrument, and communications systems.
