I wanted to share an interesting vehicle that I acquired out of Barstow/Yermo a few years ago for all you Tatra and M939 fans. From what I’ve researched this truck was put together to evaluate the Tatra system as an option for the MTVR vs Oshkosh. The truck had "test vehicle" stenciled on the door and had heavily modified brackets in the bed and bolted to the frame which I assume were used to apply load or mount test equipment. It also looked to have an early version of CTIS installed as well.
How was this put together?
From what I can tell.....Driveline and suspension are from the Tatra 815. To power this rig a N-14 Cummins mounted to an Allison HD4560P 6 speed trans. It was a tight fit for sure, and the cab and hood have been lifted 3 inches to accommodate the taller motor. Additionally, there is an air starter to get this thing going - not sure why but probably to fix clearance issues with an electric starter. Lots of switches that I’m still figuring out but it appears I can control different sets of axles from the cab. Pictures better tell the story![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Ignore the generator and air compressor mounted on the new pictures- those are so I can get it started if I lose air pressure and are not original. I will take engine and interior photos and anything other requested and post more later.
