30. Reassemble the differential case to the carrier
as described earlier, and take another backlash
and total torque-to-rotate reading. The
backlash and the preload should both be
within specification.
Checking Gear Pattern
Checking the gear pattern will help determine if
the pinion position and backlash are correct
(Figure 101).
1. Coat the entire ring gear with a thin coat of
gear paint (Figure 102).
3. Look for a centered toe pattern on both the
drive and the coast sides (Figure 104).
NOTE: Be sure not to use too much paint, or the
gears will show a false reading of interference.
2. Apply a load to the ring gear while the pinion
is turning (Figure 103). The ring gear must
spin in both directions to get patterns on the
coast and drive sides of the gear.
NOTE: It is very important that the gear pattern
on the drive side of the ring gear is in the correct
position. There are a few terms that must be
understood to determine if the gear pattern is
correct.
