Bearing Cups and Cone and Roller Assemblies

Check bearing cups for rings, scores, galling, or excessive wear. Pinion bearing cups must be solidly seated in the housing bores. Check for seating by attempting to insert a 0.04 mm (0.0015 inch) feeler gauge between these cups and the bottoms of their bores.

When operated in the bearing cups, cone and roller assemblies must turn without roughness. Examine the large roller ends for wear. If the original blend radius has worn to a sharp edge, the bearing should be replaced.

If inspection reveals either a worn bearing cup or a worn cone and roller, both parts should be replaced to avoid damage.
