PREPARE PARTS FOR
ASSEMBLY
Cleaning
• Parts with Rough Finishes — Clean parts with a
cleaning solvent and brush or hot tank the parts in a
weak alkaline solution. Wash hot tanked parts with
water to remove the alkaline solution.
• Parts with Machined or Ground Surfaces — Clean
parts with a cleaning solvent and brush. Remove
remaining gasket material using a gasket scraper,
taking care to not damage the machined surfaces.
Do not clean ground or polished parts with water,
steam, alkaline solution, or place in a hot tank.
Drying
• Dry all parts after washing using clean rags or paper
towels.
• Corrosion Prevention — Apply a light oil film to all
parts to be reused and reassembled.

pitting or damage. Replace as required.
• Bevel Gear Set — Inspect pinion and ring gear for
pitting or damage. Replace only as a matched set.
• Differential Assembly — Inspect differential case
thrust washers and thrust washer surfaces for wear
or damage. Replace differential case and thrust

for wear or damage. Replace only in matched sets.
• Planetary Wheelend — Inspect all gearing for pitting
