TOPIC 5. OIL FILTER

A. DESCRIPTION

An oil filter is installed as standard equipment in all

Power-Shift transmissions. The purpose of the filter is to

eliminate harmful contaminants from the oil and to

increase the service life of the transmission. The filter is

installed in the return line between the oil cooler and the

transmission. It is the throw-away, replaceable type and

it is recommended that it be changed every 200 hours.

Changing the filter at the prescribed interval will help

keep the transmission free of contaminants.
