Inspection After Disassembly of Carrier

- Thoroughly clean all parts. Always use new solvent when cleaning bearings.
- Do not spin dry bearings with compressed air.
- Oil the bearings immediately to prevent rusting.
- Inspect the parts for any major damage.
- Clean the inside of the housing before rebuilding.
- When a scored or chipped gearset is replaced, the axle housing must be washed thoroughly.

Inspection procedures for individual parts are outlined below.

Gears

Examine the pinion and ring gear teeth for scoring, excessive wear, nicks and chipping. Worn, scored and damaged gears cannot be rebuilt to correct a noisy condition.

Bearing Cups

NOTE: If disassembly is required, it is recommended that new bearings be installed.

Check bearing cups for deep scores, galling, or spalling. If a 0.038mm (0.0015-inch) feeler gauge can be inserted between a cup and the bottom of its bore or any point around the cup, the cup must be reseated.

Cone and Roller Assemblies

When operated in the cups, bearing rollers must turn without roughness. Examine the roller ends for step wear. If inspection reveals either a damaged cup or a damaged cone and roller assembly, both parts should be replaced.
