When using an oil bath system, do not pack the
bearing with grease. Grease will prevent the
proper circulation of axle lubricant and can cause
premature wheel seal and bearing failure.
CAUTION
!
1. Place the hub, seal end up, on
a clean work surface.
2. Lubricate the inner bearing
cone with the same lubricant
as will be used in the hub and
install it into the inner bearing
cup (see gure 35).

The seal must be replaced every time the hub is
removed from the spindle.
Do not apply any gasket sealant to the seal outer
or inner diameter.
Always use the seal installation tool specied by
the seal manufacturer. Using an improper tool can
distort or damage the seal and cause premature
seal failure.
NOTE
3. Position the seal into the hub
bore. Use a ConMet seal
installation tool or at plate and
a small mallet to install the seal.
ConMet seals require the proper tool for
installation. Refer to the tables below for
a ConMet seal installation tool or at plate
dimensions. For other seals, refer to the specic
manufacturers’ instructions.

5. Check to be certain the seal is
not cocked and that the seal
inner diameter and the inner
bearing turn freely.
Failure to lubricate the inner diameter of the seal
may result in premature seal failure.
CAUTION
!
6. Lubricate the inner diameter of
the seal with a light lm of the
same lubricant as will be used
in the hub.
7. Turn the hub over, and place it
seal end down.
8. Lubricate the outer bearing
cone with the same lubricant
as will be used in the hub and
install it into the hub assembly
(see gure 37).
