Lubrication of the Clutch Release Bearing
57X mm 25.01.001
The standard clutch release bearing is not sealed, and requires lubrication. Lubricate the bearing, as follows.
- Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires.
- Remove the clutch inspection plate to see the release bearing
while lubricating it. See Fig.
Fig. 1, Typical Clutch Inspection Plate
- Clean the grease fitting. On some vehicles, a lube tube
will be used and the fitting may be at the 9-o'clock position on the
left side of the bellhousing. See Fig..
Fig. 2, Typical Release Bearing Grease Fitting
- Using a pressure-type grease gun, lubricate the release bearing with NLGI Grade 3 grease until excess grease purges from the rear of the release bearing (toward the transmission).
- Wipe excess purged grease from the bearing.
- Install the clutch inspection plate.
Note: On vehicles equipped with Detroit transmissions, the release bearing does not need to be lubricated.
Note: On vehicles equipped with Eaton Fuller UltraShift PLUS transmissions, lubricate the release bearing every 50,000 miles (80 450 km) or three months.
Notice: 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.
