OK here goes.
The baby HEMTT is a 4X4 project truck I thought up as a toy. Old retired guy with vivid imagination and a few mechanical skills = dangerous combination.
It's based on an M35 deuce frame stripped and refitted w/ M900 series 5 ton axles (full air brakes, not air over hydraulic). Rear axle is from a USMC truck which means limited slip diff.
Tires are 16oo X 20s on Budd "garbage truck wheels" to give the correct width and offset.
To give it the HEMTT look it's set up with an LVS (USMC HEMTT) cab w/ second rear window installed behind the passenger seat for extra visibility.
Powerplant is a Cummins 5.9 Turbo Diesel From a Freightliner coupled to an Allison AT545n automatic. The Freightliner configuration means the engine has a bolt-on Bendix Tu-Flow 550 air compressor; gear driven, not belt driven. The Allison also has PTO style accessory drive one side of which runs a hydraulic pump for the material handling crane, "low" turbo mount and is intercooled.
Steering is through a Ross box originally from a Mack cab-over that was chosen because when mounted and connected to the steering shaft will point the truck in the same direction the steering wheel is turned (all other boxes reversed direction and became steer left, go right set-ups. Steering box mounts almost directly over the front axle so the box pitman arm runs a drag link that goes back to a repeater pitman arm then forward to the axle. That gives enough length to the drag link so that the truck doesn't try to "self-steer" in rough terrain.
Deuce bed has been shortened and located to create room for a Grove Material Handling Crane as well as the walkway around the rear of the engine.
All mounting hardware pieces and parts are my own construction based on the original HEMTT and Oshkosh design components. In order to make sure I was accurately reproducing any given mount or bracket I've collected about 6GB of photographs, drawings, blueprints, etc. of data including construction details during the build.
I've also got a little over 2GB of military TMs in my PDF library, almost half of which is vehicle and HEMTT-related. I'd probably just copy the entire folders onto a flash drive for someone else to sort through. Lots of juicy stuff there for someone's library.
All the heavy construction is done and the truck is to the wiring, air, hydraulic and coolant systems completion stage.
I even collected a complete set of stencils and stickers to be applied once the truck was done and painted. CARC paint for the truck is there although I'm not sure of it's viability. The cans, never opened, are still in their cases and its the later stuff that was moisture triggered for curing.
To do the proper wiring job I've collected a whole kit of Packard waterproof connector pieces including the special crimping tool that locks the wire end on without distorting the terminal.
All this stuff goes with the baby HEMTT so the new owner won't have to start from square one.
