Cleaning

Proper cleaning requires complete

disassembly.

The differential carrier assembly may be

steam cleaned only while mounted in

housing provided all openings are plugged.

Wash steel parts with machined surfaces in

a commercial solvent.

Wash castings or other rough parts in

solvent or clean in hot solution tanks using

mild alkali solutions, heating parts

thoroughly before rinsing.

Rinse all parts thoroughly. Dry immediately

with clean rags. Lightly oil parts and wrap

in corrosion-resistant paper if not reused

immediately. Store parts in a clean,

dry place.

Inspection

All axle components should be closely

inspected after cleaning to determine

which require replacement. For more

detailed inspection guidelines and failure

analysis, see Spicer Failure Analysis

Service Manual AXSM-0020

In General:

Inspect steel parts for notches, visible steps

or grooves. Look for scuffing, deformation

or discoloration related to improper

lubrication.

Inspect gear teeth for signs of excessive

wear, pitting or cracking along contact

lines before reusing. Check tooth contact

pattern.

Inspect machined surfaces of cast or

malleable parts for cracks, scoring, and

wear. Look for elongation of drilled holes,

wear on machined surfaces and nicks or

burrs in mating surfaces.

Inspect fasteners for rounded heads, bends,

cracks or damaged threads.
The axle housing should be inspected for

cracks or leaks, loose studs or cross-

threaded holes.

A

CAUTION: Any damage which affects

the alignment or structural integrity of the

housing requires housing replacement.

Repair by welding or straightening should

not be attempted. This process can affect

the housing metallurgy and cause it to fail

completely when under load.

Repair and Replacement

Replace lower-cost parts, such as thrust

washers, seals, etc., that protect the axle

from premature wear and do not add

greatly to the cost of your rebuild.

Replace heavily worn but unbroken parts,

since the damage done, should they fail,

would greatly exceed their replacement cost.
Steel parts such as shafts or gears are not

repairable. If worn or damaged, they should

be replaced, along with mating parts as

necessary.

Seals and washers should be routinely

replaced. Fasteners with self-locking

patches may be reused if secured with

several drops of Loctite #277.
Axle housing repairs are limited to removal

of nicks or burrs on machined surfaces or

replacement of damaged studs.

WARNING: Gasoline is not an

acceptable cleaning solvent because

of its extreme combustibility. It is

unsafe in the workshop environment.
