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

could result in serious personal injury or death.
25–01 Eaton Fuller Heavy-Duty
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.
See
5.
Install the clutch inspection plate, if removed.
25–02 Clutch Release Cross-
Shaft Lubrication

™
Clutch Release Bearing
Lubrication
If the clutch is equipped with an optional sealed
clutch release bearing, lubricate the bronze bushing
located between the clutch bearing housing and the
transmission input shaft. Use a pressure-type grease
gun with Meritor Specification 0-661 Lithium Complex
Grease, NLGI Grade 3, and lubricate until grease
flows from the release bearing housing. Depress the
clutch pedal a couple of times before starting the
engine.
If the clutch is equipped with a standard non-sealed
clutch release bearing with a grease fitting, lubricate
the bearing as follows:
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 that ex-
tends outside of the clutch housing. It is not
necessary to remove the clutch inspection plate
when the lubrication extension is used.
2.
Remove the clutch inspection plate, if necessary.
See
NOTE: For lubrication of the release bearing,
use Meritor Specification 0-661 Lithium Complex
Grease, NLGI Grade 3.
3.
Wipe any dirt from the grease fitting. See
Using a pressure-type grease gun equipped with
recommended grease, lubricate the bearing until
excess grease purges from the rear of the re-
lease 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.
