BEARING INSPECTION

Wash all grease and oil from the bearing cone using a suitable solvent. Dry the bearing with a clean, lint-free cloth and inspect each roller completely. If any pitting, spalling, or corrosion is present then the bearing should be replaced. The bearing cup inside the hub should likewise be inspected.

When replacing the bearing cup proceed as follows:

1. Place the hub on a flat work surface with the cup to be replaced on the bottom side.
2. Using the brass drift punch, carefully tap around the small diameter end of the cup to drive out.
3. After cleaning the hub bore area, install the new 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.
4. Replace bearings using standard installation and greasing procedures. (Consult replacement bearing manufacturer’s specifications for details)
