equipped with an optional clutch release bearing 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 away from the grease fitting. See
Fig. 1. Use a pressure-type grease gun
equipped with the recommended grease, and
lubricate the bearing until excess grease purges
from the rear of the release 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 the sleeve-bushing contact
points. See Fig. 2.
5. Install the clutch inspection plate.
6. Remove the chocks.
