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.

Clutch Release Bearing
Lubrication
1.
Park the vehicle on a level surface. Apply the
parking brakes, and chock the rear tires.
NOTE: Some clutch release bearings are
equipped with a lubrication extension, or lube
tube, that extends outside of the clutch housing.
2.
Remove the clutch inspection plate. See
NOTE: For lubrication of the release bearing,
Eaton Fuller recommends NLGI Grade 2 or 3
EP lithium grease with a 325°F (163°C) operat-
ing temperature, or Roadranger Grease MP-2.
3.
Wipe any dirt away from the grease fitting. See
. 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).
NOTICE
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.
