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, 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
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, 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,
Eaton Fuller recommends a lithium-base high-
temperature grease that meets the NLGI grade
one or two specification.
3. Wipe any dirt away from the grease fitting. See
Fig. 1 . Using a pressure-type grease gun
equipped with the recommended grease, lubri-
cate 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, then remove
the chocks.
