Bearing Cups and Cone and Roller Assemblies

Check bearing cups for rings, scores, galling, or excessively worn wear patterns. Differential drive pinion bearing cups (4616) must be solidly seated. Check for seating by attempting to insert a 0.04mm (0.0015 inch) feeler between these differential drive pinion bearing cups and the bottoms of their bores.

When operated in the differential drive pinion bearing cups , differential pinion bearings (4630) must turn without roughness. Examine the large roller ends for wear. If the original blend radius has worn to a sharp edge, the differential pinion bearing should be replaced.

If inspection reveals either a worn differential drive pinion bearing cup or a worn differential pinion bearing , both parts should be replaced to avoid damage.
