3. Adjust until the standard value is obtained.
Standard backlash
0.13 — 0.18 mm (0.0051 — 0.0071 in)
Adjust the backlash by turning the side retainer in the RH side case.

NOTE:
Each time side retainer rotates one tooth, backlash changes by 0.05 mm (0.002 in).
3. TOOTH CONTACT OF HYPOID GEAR
1. Adjust until correct teeth contact is obtained.
2. Check tooth contact, and perform the adjustment as follows.
• Tooth contact
Check item: Tooth contact surface is slightly shifted toward the toe side under a no-load condition. (When driving, it moves towards the heel side.)
|
(A) |
Toe side |
|
(B) |
Heel side |
• Face contact
Check item: Backlash is too large.
Contact pattern
Corrective action: Tighten the side retainer to move the driven gear closer to the drive pinion.
• Flank contact
Check item: Backlash is too small.
Contact pattern
Corrective action: Loosen the side retainer to move the driven gear away from the drive pinion.
• Toe contact (inside contact)
Check item: Teeth contact area is too small.
Contact pattern
Corrective action: Increase thickness of the drive pinion shim according to the procedures for moving the drive pinion closer to the driven gear.
• Heel contact (outside end contact)
Check item: Teeth contact area is too small.
Contact pattern
Corrective action: Reduce the thickness of the drive pinion shim according to the procedure for moving the drive pinion away from the driven gear.
