If any pitting, spalling, or corrosion is present, then the bearing must be
replaced. The bearing cup inside the hub must be inspected.
IMPORTANT: Bearings must always be replaced in sets of a cone and a cup.
CAUTION
Be sure to wear safety glasses when removing or installing force
fitted parts. Failure to comply may result in serious eye injury.
When replacing the bearing cup proceed as follows:
1. Place the hub on a at work surface with the cup to be replaced on the
bottom side.
2. Using a brass drift punch, carefully tap around the small diameter end of
the cup to drive out.
3. After cleaning the hub bore
area, replace the cup by
tapping in with the brass drift
punch. Be sure the cup is
seated all the way up against
the retaining shoulder in the
hub.
Replace only with bearings as specied
in the Bearing Replacement Chart.
