A. Using dial indicator at backface of gear, loosen the
bearing adjusting nut on the side opposite gear only
sufficient to notice end play on the indicator
B. Tighten the same adjusting nut only sufficient to obtain .00 end play.
C. Check gear for runout. If runout exceeds .008", remove differential and check for cause.
D. Tighten adjusting nuts one notch each from .000 end play to preload differential bearings.
7. Check Hypoid Gear Backlash.
If the drive gear is not going to be replaced, we suggest
the established backlash recorded before disassembly
be used. For new gears the new backlash should be
initially set at .010". Adjust backlash by moving the gear
only. This is done by backing off one adjusting ring and
advancing the opposite ring the same amount.
