Lubrication
Bearing Plate (Full Round) Universal Joints
1. There will occasionally be one or more bearing
assembly seals that will not purge. Release seal ten-
sion by loosening the bolts holding the bearing
assembly that does not purge. It may be necessary
to loosen the bearing assembly approximately 1/16"
minimum. If loosening it does not cause purging,
remove the bearing assembly to determine the cause
of blockage.
Note: It is essential that all seals be completely purged of old
grease and contaminants. If fresh grease can be seen at
these seals, the purging process is complete, and the
universal joint is properly lubricated.
Note: Spalling and/or brinelling can be caused if contami-
nants (water, air, etc.) are left in the universal joint and/
or the bearing seals. Purge old grease thoroughly.
2. Install new bolts, and torque to specifications in the
above table.
Snap Ring Universal Joints
1. There will occasionally be one or more bearing
assembly seals that will not purge. If any of the seals
will not purge, replacement of the universal joint kit
is necessary. See the Reassembly - Inboard Slip
Style under “Center Bearing Assembly” on page 20
for proper replacement procedures.
