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 Clutch Release Bearing
Lubrication
The standard clutch release bearing is not sealed,
and requires lubrication. Lubricate the bearing, as
follows.
NOTE: On vehicles equipped with Detroit trans-
missions, the release bearing does not need to
be lubricated. On vehicles equipped with Eaton
Fuller UltraShift PLUS transmissions, lubricate
the release bearing every 50,000 miles (80 000
km) or 3 months.
1. Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires.
2. Remove the clutch inspection plate to see the
release bearing while lubricating it. See
Fig. 1 .
3. 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 bell-
housing (see
Fig. 2 ).
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. Using a pressure-type grease gun, lubricate the
release bearing with NLGI Grade 3 grease until
excess grease purges from the rear of the re-
lease bearing (toward the transmission).
5. Install the clutch inspection plate.
