This illustration shows the location of the following main power train components for the D7E Track-type Tractor:
APC (1)
Power inverter (2)
Generator ECM (3)
Motor ECM (4)
Propulsion module (5)
Generator (6)
The power train oil pump (7) draws oil from the power train oil tank (8) and sends the oil through the power train oil filter (9) to the power train oil cooler (10). The cooled power train oil is used to cool the rotors of the generator and propulsion module. The power train oil also lubricates the components of the propulsion module.
