Pinion Bearing: Testing and Inspection
Inspection After Disassembly
-
Check bearing cups for rings, scores, galling or excessive wear. Pinion cups must be solidly seated. Check for seating by attempting to insert a
0.04 mm (0.0015 inch) feeler 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 assembly, both parts should be replaced to avoid damage.
