The water pump is driven by a gear and is located onthe right hand side of the engine. The water pump
supplies the coolant for the engine cooling system. The coolant is supplied to the following components:
Engine oil cooler, Cylinder head, Cylinder liner, and Aftercooler. The aftercooler has its own water pump.
This work package addresses the following systems:Engine Electrical, Powertrain Control ECM, and
Engine Electronic Control.
The engine electrical system addresses the following topics: Grounding practices, Charging, and Starting.
The powertrain control system addesses the following controls and operations: Electronic Clutch Pressure
control, Transmission Shifting operation, Electronic Brake control, Auto shift operation, and Electronic
Hydraulic Implement Control.
The engine electronic control systemis integrally designed into the engine's fuel system and engine's air
inlet and exhaust system in order to electronically control the fuel delivery and the injection timing.
The engine is the source of the mechanical power. Po er flows from the engine to tracks through the pow-
ertrain: torque divider, drive shaft, power shift transmission, bevel and transfer gears, steering differential
and brake, planetary gears and brake, and final drives.
This work package addresses the following systems:Powertrain Hydraulics, Powertrain Electronic Con-
trols, Transmission, and Transmission Hydraulic Controls.
FINAL DRIVE AND UNDERCARRIAGE
The final drives take power from the outer axle shafts and sends the power to the tracks. The final drives
give a double reduction through the planetary gears.
The undercarriage of the machine is not suspended. Pivot shafts connect the roller frames at the rear of
This work package addresses the following: Standardundercarriage arrangements, Pivot shaft, Equalizer
bar, Track roller frame, and Track.
IMPLEMENT AND STEERING HYDRAULIC
The machine is equipped with an implement system thatis controlled by the operator and hydraulically
actuated. The hydraulic system includes a bulldozer and a ripper or a winch.
This work package addresses the following: HydraulicTank, Oil Cooler, Piston Pumps, and Control Valves
for both Implements and Steering systems.
The six components of the manual orifice tube sysem are the following: orifice tube, accumulator, com-
The heating system uses the coolant from the engine cooling system to heat the operator compartment.
