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.

Inspection

It is very important to inspect all parts carefully before
the axle is reassembled. Replace all damaged parts.
• All Seals/Gaskets — Replace only, do not reuse.
• All Bearings — Inspect all bearings, cups and cones
for pitting or damage. Replace as required.
• All Castings — Inspect for damage or cracking.
Replace as required. Do not weld.
• Drop/Reduction Gear set — Inspect both gears for
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
washers as matched sets only. Inspect differential
spider and pinion gears for wear or damage. Replace
only in matched sets. Inspect differential side gears
for wear or damage. Replace only in matched sets.
• Planetary Wheelend — Inspect all gearing for pitting
or damage. Replace as required.
• Axle Shafts — Inspect both axle shafts for spline wear
and evidence of torsional cracking. Mount shafts
between centers and check for a maximum of 0.010
inch shaft runout. Replace if wear, cracks or excessive
runout observed.
