25–02 Clutch Release Cross-
Shaft Lubrication
The clutch release cross-shaft is equipped with two
grease fittings in the transmission clutch housing.
See
Fig. 3 and Fig. 4 . Wipe any dirt from the grease
fittings, and lubricate with multipurpose chassis
grease.
25–03 Sleeve Assembly Bronze
Bushing Lubrication
Vehicles equipped with the sealed clutch release
bearing require lubrication of the bronze bushing lo-
cated between the clutch bearing housing and the
transmission input shaft. Use a pressure-type grease
gun equipped with high-temperature grease only, and
lubricate until grease flows from the release bearing
housing. Depress the clutch pedal a couple of times
before starting the engine.
25–04 Meritor Clutch Release
Bearing Lubrication
The standard clutch release bearing is not sealed,
and requires lubrication. If the vehicle is not
equipped with an optional sealed clutch release bear-
ing with a grease fitting, lubricate the bearing as
follows:
1. Park the vehicle on a level surface. Apply the
parking brakes, and chock the rear tires.
2. Remove the clutch inspection plate.
NOTE: Some clutch release bearings are
equipped with a lubrication extension that ex-
tends outside of the clutch housing. It is not
necessary to remove the clutch inspection plate
when the lubrication extension is used.
NOTE: For lubrication of the release bearing,
Meritor recommends a lithium-base high-
temperature grease that meets the NLGI grade
three specification.
3. Wipe any dirt from the grease fitting. See Fig. 1 .
Using a pressure-type grease gun equipped with
recommended grease, lubricate the bearing until
excess grease purges from the rear of the re-
lease bearing (toward the transmission).
CAUTION
Do not over-lubricate the clutch release bearing.
Over-lubrication could contaminate the clutch in-
ternally, causing clutch slippage and premature
failure. Do not use chassis grease or multipurpose
lubricants.
