Change Backlash Setting
If you have too much backlash the ring gear needs to move
closer to the pinion. Back off the plain half adjuster, and count
the number of notches you backed it off. Each notch equals
about 0.003" of backlash.
IMPORTANT: In order to maintain the differential bearing pre-
load you will need to turn the flange half bearing adjuster the
same amount in the same direction. If you need more back-
lash reverse this procedure.
Recheck Backlash
1. Install carrier bearing caps and torque carrier cap
bolts to specifications outlined in the back of this
publication.
2. If the bearing adjusters were not in straight or fully
seated the backlash will change.
a. Used Gearing: Reset to backlash recorded
before disassembly.
b. New Gearing: Backlash should be between
0.008" and 0.018".
3. Check ring gear tooth contact pattern. Paint ring gear
teeth and check tooth contact pattern. Correct tooth
patterns. Check adjusting procedures outlined in this
section.
4. Install bearing adjuster cotter pins.
Measure Ring Gear Runout
1. Measure ring gear total radial run out. (Indicator
reading should not exceed 0.010").
2. Measure ring gear total backface runout. (Indicator
reading should not exceed 0.010").
