DESCRIPTION AND OPERATION
Numbers in parentheses refer to Fig. 1.
The air cooled hydraulic oil cooler (4) is mounted on
the front of the radiator assembly with the purpose of
cooling hydraulic oil circulating through the hydraulic
system.
Hydraulic oil cooler (4) is connected at diverter tube
(31) between the return port on the body control valve
and the inlet to the hydraulic tank filter assembly.
Note: When hydraulic oil cooler (4) is fitted, the return
port used is the port on the body control valve
normally fitted with a blanking plate. Refer to Section
230-0060, BODY CONTROL VALVE.
Hydraulic oil enters the top port on hydraulic oil cooler (4)
through oil inlet line (8) from diverter tube (31). Oil passes
through a series of tubes in the cooler core, where the oil
temperature is reduced by air flow through the cooler fins,
