Seal Inspection and Replacement
Whenever the hub is removed, inspect the seal to assure that it is not
nicked or torn and is still capable of properly sealing the bearing cavity. If there is any question of condition, replace the seal. Use only the seals specified in the Seal Replacement Chart. To replace the seal:
-
Pry the seal out of the hub with a screwdriver.
Never drive the seal out
with the inner bearing asyou may damage the bearing.
- Apply a PERMATEX sealant to the outside of
the new seal.
- Tap the new seal into place using a clean wood block.
Bearing Adjustment and Hub Replacement
If the hub has been removed or bearing adjustment is required, the following adjustment procedure must be followed:
- After placing the hub, bearings, washers, and spindle nut back on the axle spindle in reverse order as detailed on the previous page
on hub removal, rotate the hub assembly slowly while tightening the spindle not to approximately 50
Ibs.-ft. (12" wrench or pliers
with full hand force.)
- Then loosen the spindle nut to remove the torque. Do not rotate the hub.
- Finger tighten the spindle nut until just snug.
- Back the spindle nut out slightly until the first castellation lines up
with the cotter key hole and insert the cotter pin (or locking tang
in the case of E-Z Lube.)
- Bend over the cotter pin legs to secure the nut (or locking tang in
the case of E-Z Lube.)
- Nut should be free to move with only restraint being the cotter pin
(or locking tang.)
