YaMZ-850.10-01The YaMZ-850 engines were developed on the basis of the YaMZ-8401 family and are intended for use in industrial tractors, bulldozers and pipe layers. On the basis of the YaMZ-850.10 tractor diesel engine, several modifications have been made for use as part of stationary installations. So the diesel unit YaMZ-8502.10 is used to drive pumps and compressors, YaMZ-8503.10 for diesel power plants (diesel generators) of high power, YaMZ-E8504.10 for driving drilling equipment. The presence of the letter E in the diesel model indicates that the engine is experimental (not serial production). The 850.10 engine is designed for installation on mining dump trucks with a total weight of up to 95 tons.
