POWERTRAIN
0003
1.
Engine (1) - is a liquid cooled, in-line 6-cylinder, 4-cycle, turbocharged/charge air cooled compression ignition engine.
The engine develops 200 brake horsepower at 2,300 rpm and maximum rated speed of 2,500 rpm and is capable of being
run on JP-8. The engine delivers power to the transmission (2).
2.
Transmission (2) - the transmission provides power to the front and rear axle drive heads. There are six forward and two
reverse gears. The transmission has a selectable 4-wheel-drive option.
3.
Axles - the axles transmit the power to the road wheels. Both axles are fitted with torque limiting differentials and differ-
ential locks. Both front and rear axles steer.

COOLING SYSTEM
0003
1.
Air Intake Grille - allows air to enter the engine compartment.
2.
Air Blast Radiators - a combined cooling pack, comprising a condenser, charge air cooler, transmission oil cooler,
hydraulic system cooler, and engine radiator.
3.
Condenser - allows the refrigerant gas contained in the machine A/C system to be cooled and condensed. As the refriger-
ant gas flows through the system, air is drawn over the condenser by machine movement and the action of the engine
cooling fan removing excess heat.
4.
Charge Air Cooler (1) - allows cooling of the turbocharged induction air for the engine. This cooling increases the den-
sity of the air, which helps the engine run more efficiently. As the charged air flows around the system, air is drawn over
the cooling radiator by machine movement and the action of the engine cooling fan removing excess heat.
