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.
Ring gear and pinion
must be replaced as an assembly.
3.
Inspect differential case for cracks, damage, distortion, worn side gear bores and scored bearing surfaces, and replace as needed.
