2. ADJUSTING THE GEARSET BACKLASH
Backlash specification : 0.13~0.18mm
If the old gearset is installed, adjust the
backlash to the setting that was measured
before the carrier was disassembled.
If a new gearset is installed, adjust the
backlash to the correct specification for new
gearsets.
1)
Attach a dial indicator on the mounting
flange of the carrier.
2)
Adjust the dial indicator so that the plunger
or pointer is against the tooth surface, near
the heel end of the gear tooth. Set the
indicator dial to zero(0).
3)
Hold the drive pinion in position.
4)
Read the dial indicator, while rotating the
ring gear a small amount in both directions,
against the drive pinion teeth.
When you adjust backlash, move the ring
gear ONLY. DO NOT move the drive pinion.
5)
If the backlash reading is within specifi-
cation, continue checking tooth contact
patterns.
Otherwise, adjust backlash. Refer to step
6), and check, following steps 1)-4).
Backlash is increased by moving the ring
gear away from the drive pinion. Backlash
is decreased by moving the ring gear
toward the drive pinion.
6)
Loosen one bearing adjusting ring one
notch, then tighten the opposite ring the
same amount.
