Differential: 3B-32
• Install the left and right side shims (2) and final driven
gear assembly (1).
• Install the final gear case cover, and then tighten the
bolts to the specified torque diagonally.
Tightening torque
Final gear case cover bolt (a): 23 N·m (2.3 kgf-m,
16.5 lb-ft)
NOTE
At this time, it is not necessary to install the
gear case cover’s O-ring.
• Rotate the final driven gear several turns in each
direction. This will provide connect pattern on the
coated teeth of the gear.
• Remove the final driven gear and compare the coated
teeth to the examples shown in [A], [B] and [C].
• If tooth contact is found to be incorrect (examples [A]
and [C]), the shim between the final drive gear bearing
and gear case must be changed and the tooth contact
should be re-checked until the tooth contact is found
to be correct (example [B]).
CAUTION
!
Make sure to check the backlash and shim
thickness after the tooth contact has been
adjusted, since it may have changed. Adjust
the tooth contact and backlash until they are
both within specification. If the correct tooth
contact cannot be maintained when adjusting
the backlash, replace the final drive gear and
final driven gear as a set.
