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 they 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, and worn or scored side gear bores and bearing surfaces. Replace case if damaged or
scored.
4.
Inspect axle and pinion housings 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 ring gear and side bearings in housing, adjust side bearings to zero preload and check ring gear runout with dial
indicator bearing against machined edge of gear.
9.
If ring gear runout exceeds .003 inch and gear cannot be repositioned to reduce runout, replace ring gear and/or case assembly.

1.
If side bearings are to be replaced, remove bearings using suitable puller, ensuring that puller jaws are seated in case notches and pulling against
side bearing inner race.
2.
Remove ring gear retaining bolts and lockwashers, then the ring gear, using soft faced hammer to tap gear from case.
Do not pry gear from case
as machined surfaces will be damaged.
3.
Scribe matching mark between differential case halves, then separate cover from case.
4.
Remove differential pinion, pinion yoke, side gears and thrust washers from case, noting installation position for assembly.
5.
Inspect components. Refer to
Cleaning and Inspection, and replace as needed. See: Corporate and Eaton/10 1/2 Inch Ring Gear/Cleaning &

If components are to be reused, they must be installed in original position. Coat all components with specified lubricant prior to
installation.
6.
Install differential pinions and thrust washers on yoke.
7.
Install side gears and thrust washers in case halves, then position yoke and pinion assembly on flanged case half.
8.
Hold side gear into case cover and join case halves, ensuring that matching marks are aligned and that gears are properly meshed.
9.
Install ring gear, retaining bolts and lock washers, then evenly torque ring gear bolts to 110 ft. lbs.
10.
Install case side bearings, using suitable driver to seat bearings.
Support case on suitable pilot when installing second side bearing to prevent
damaging bearing already installed.
