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
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.
4. Wipe off excess grease, and apply it to both the
yoke finger and sleeve bushing contact points.
See Fig. 2.
5. Install the clutch inspection plate, then remove
the chocks.
