vice Procedure
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 .003" of backlash.
In order to maintain the differential bearing preload you will
need to turn the flange half bearing adjuster the same
amount in the same direction. If you need more backlash
reverse this procedure.
Procedure -
1. Install carrier bearing caps and torque carrier cap
bolts to specifications outlined in the back of this
publication.
2. Recheck Backlash: 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 .008 and
.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
