Eaton Fuller Clutch Release Bearing Lubricating

The standard clutch release bearing is sealed, and does not require lubrication. If the vehicle is not equipped with a maintenance-free sealed clutch release bearing, lubricate the bearing as follows:
1.
Park the vehicle on a level surface. Apply the parking brake, and chock the rear tires.
2.
Remove the clutch inspection plate.
NOTE: Some clutch release bearings are equipped with a lubrication extension that extends outside of the clutch housing. It is not necessary to remove the clutch inspection plate when the lubrication extension is used.
For lubricating the release bearing, Eaton Fuller recommends a lithium-base high-temperature grease that meets the NLGI Grade 1 or 2 specification.
3.
Wipe the dirt away from the grease fitting. See Fig. 1 . Use a low-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 internally, causing clutch slippage and premature failure. Do not use chassis grease or multipurpose lubricants.
4.
Wipe off excess grease and apply to both the yoke finger and sleeve bushing contact points. See Fig. 2 .

5.

Remove the chocks.
