THis 1983 AM General M-931 is the most desirable of the 939 series. It does not have the ABS or the CTIS tire inflation system found in later models which were troublesome and maintenance intensive. It also features the less costly 1100×20 tires as opposed to the A1 and A2 series tires. It is equipped with the larger displacement Cummins NHC-250 diesel which is a prove design and much more suited to a truck with this capacity than the 504 cubic inch 8.3 Cummins of the A1 and A2 series.
This particular 931 has spent its entire life at the Marine Corp Base in the high desert of Barstow California running back and forth on the base. It received routine service and inspections. It had only 370 miles on it when current owner purchased it. Road testing and maintenance checks put an additional 38 miles on it to make the current mileage 288.
The truck has never been molested or butchered in a government rebuild program. It is original to the way it cameos the AM Generals assembly line with the exception of the undercoating applied to the underside of the cab, hood, frame and undercarriage by the military while it was in service (this prevented the rust normally found in these trucks) and the following upgrades that were done by an ASE certified master medium/heavy truck technician:
- Installed rare Cummins/Fleetrite spin-on lube oil filter adapter (no more messy canisters)
- New Gates brand engine fan and accessory drive belts
- Mil Spec transfer case low-range/reverse lockout kit
The NHC 250 Cummins starts instantly and runs and performs like a new engine (which it is). The Allison transmission shifts smoothly with no hesitation or slippage. All components and accessories function as would be expected. Truck operates on and off road as it should, as does the air shift front axle and brake system. Rear axles are equipped with full-locking differentials.
The fifth wheel showed no sign of even having been greased or hooked to a trailer when purchased. It has been coupled and uncoupled to a trailer to verify the jaws and lock function as intended.
All original DRMO discharge markings, chalk marks and numbers are on the unit to verify it was received from Barstow. Proves it is the real deal! It will take less than a day for seller to paint over the markings so the truck is a show piece.
This is one of the cleanest 931 tractors you will find and is as close to a “brand new” 1983 AM General as you will find.
Potential buyers are encouraged to inspect this truck in person…you will not be disappointed!
