Cleaning & Inspection


1. Clean components in suitable solvent and blow dry with compressed air, noting the following:
a. Do not use brush when cleaning bearings.
b. Do not ``spin dry'' bearings as bearings will be damaged.
c. Lightly lubricate components after cleaning to retard corrosion.
d. Keep all components in order to ensure proper assembly.
2. Inspect gears for cracks, chipped or broken teeth, wear and scoring. Replace gears that are damaged or excessively worn.
3. Inspect differential case for cracks, damage, distortion, worn side gear bores and scored bearing surfaces, and replace as needed.
4. Inspect housing for scored bearing mount surfaces, cracks and distortion, and replace as needed. Ensure that housing is clean and free from foreign material.
5. Inspect bearing rollers and races for pitting, scoring, overheating and damage.
6. Mate each bearing with race and check operation.
7. Replace any bearing assembly that is damaged, excessively worn, or that fails to operate smoothly.
8. Mount differential case along with side bearings and ring gear in housing, adjust side bearings to zero preload and check ring gear runout with dial indicator bearing against machined edge of gear.
