DESCRIPTION AND OPERATION
Numbers in parentheses refer to Fig. 1. The disc brake
oil cooler can be identified as item 6 in Section 210-
0005, COOLING SYSTEM SCHEMATIC.
The disc brake oil cooler is a blast air type, mounted
on the right hand fender adjacent to the main hydraulic
tank. The fan (7) within the brake oil cooler is driven by
a hydraulic motor (10). The motor (10) is supplied by a
dedicated brake cooling section of the triple gear pump,
via two speed control valve. The speed of the fan (7) is
dependant on the oil flow being supplied to the motor
(10) from the two speed control valve. Refer to Section
250-0065, TWO SPEED CONTROL VALVE.
Brake cooling oil enters the top of the oil cooler (3) and
flows through the oil cooler (3) before exiting at the
bottom. There are three inlet ports and three outlet
ports, one for each axle.
