POWER PLANT COMPONENTS

The power plant consists of three main components:

Engine (1) is a liquid cooled, V-type, six cylinder, compression ignition (CI) unit. Starting is by a heavy duty 24 volt starter

(2). Engine is protected from low oil pressures and high temperatures by switches in the oil and cooling systems which

activate warning light circuits.

Transfer gearcase (3) is a compact unit that transfers power from engine flywheel to transmission torque converter. An engine

disconnect allows the engine to run without transferring power to the transmission. A power takeoff drives the differential oil

pump (4) and a ramp pump (5). Another power takeoff drives the cooling fan (6), and a third drives the generator (7).

Transmission (8) is a three speed, constant mesh, planetary gear train with hydraulic torque converter and lockup clutch. It

automatically selects the proper gear based on road, load conditions, and range selected.
