GENERAL
The power train system provides and uses power for moving the F-5070 Dump Truck and supplies power to the hydraulic
system. It consists of the engine, torque converter, main transmission, auxiliary transmission, power takeoff, propeller
shafts, power divider, and tandem rear axles. These systems are put together to make an efficient, load-carrying vehicle.
Since each individual system Is designed to work together with the others, no one system can function entirely on its own.
The following paragraphs explain the operation of each individual system for the purpose of making their functions easier
to understand.
