4. Remove the cotter pin from the spindle nut.
5. Unscrew the spindle nut and remove the spindle washer.
6. Remove the hub from the spindle, being careful not to allow the outer bearing
cone to fall out. The inner bearing cone should be retained by the grease seal.
Brake Drum Inspection
The critical surface of the brake drum is the contact area for the brake shoes during
stopping. Check for excessive wear or heavy scoring. If the drum is scored or out of
round, it should be machined. For a 12" brake drum, the inside diameter must be no
greater than 12.090" after machining.
Bearing Inspection
Wash all grease and oil from the bearing cone using a suitable solvent. Dry the
bearing with compressed air or a lint-free cloth and inspect each roller completely. Also
clean and inspect the cups (races) inside the hub. Any pitting, spalling, bluing (heat
damage) or corrosion is cause for replacement.
NOTE:
Bearings must always be replaced in sets of a cone and cup.
RISK OF PERSONAL INJURY!
Be sure to wear safety glasses when performing the following proce-
dure. Failure to do so can result in serious injury.
To remove the bearing cup from the hub, proceed as follows:
1. Place the hub on a flat work surface with the cup to be removed on the bottom
side.
2. Using a brass drift punch, carefully tap around the small diameter end of the cup
to drive it out.
3. After cleaning the hub bore area, tap in the new cup with the brass drift. Work
gently around the perimeter of the cup so as not to distort it. Make sure that it is fully
seated against the retaining shoulder in the hub.
