25–00 Safety Precautions
Safety Precautions in this section apply to all
procedures within this group.
DANGER
When working on the vehicle, shut down the en-
gine or motor, set the parking brake, and chock
the tires. Before working under the vehicle, always
place jack stands under the frame rails to ensure
the vehicle cannot drop. Failure to follow these
steps could result in serious personal injury or
death.
25–01 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 re-
lease 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 ex-
tends 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 speci-
fication.
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 in-
ternally, 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. Install the clutch inspection plate.
6. Remove the chocks.
