COOLING SYSTEM - Transmission Oil Cooler
SM - 3336
DESCRIPTION AND OPERATION
Numbers in parentheses refer to Fig. 1.
The transmission oil cooler is mounted on the inside
of the right hand tractor frame rail and is connected in
the water cooling and transmission oil circuits,
between the radiator and transmission. The purpose
of the transmission oil cooler is to maintain the
transmission oil within its required operating
temperature range.
Coolant is pumped from the engine water pump
through water inlet pipe (3) and into oil cooler
assembly (1). Coolant circulates through cooler tubes
in oil cooler assembly (1) cooling transmission oil
around the tubes and then flows through water outlet
pipe (4) and into the engine oil cooler.
Transmission oil to be cooled enters oil cooler
assembly (1) through oil inlet line (7), circulates
around the cooler tubes within oil cooler assembly
(1), and exits through oil outlet line (8) to return to the
transmission.
Note: To obtain the maximum cooling effect, oil flow
must always flow in the opposite direction to coolant
flow through the transmission oil cooler assembly.
REMOVAL
Numbers in parentheses refer to Fig. 1, unless
otherwise specified.
WARNING
To prevent personal injury and property
damage, be sure wheel blocks, blocking
materials and lifting equipment are properly
secured and of adequate capacity to do the job
safely.
