3. TOOTH CONTACT OF HYPOID GEAR
1. Adjust until correct teeth contact is obtained.
2. Check tooth contact, and perform the adjustment as follows.
• Correct 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.)

(B) |
Heel side |
• Face contact
Check item: Backlash is too large.
Contact pattern
Corrective action: Reduce thickness of the pinion height adjusting washer in order to bring the drive pinion closer to the driven gear.
• Flank contact
Check item: Backlash is too small.
Contact pattern
Adjustment: Increase the thickness of the pinion height adjusting washer according to the procedure for moving the drive pinion away from the driven gear.
• Toe contact (inside contact)
Check item: Teeth contact area is too small.
Contact pattern
Corrective action: Increase the thickness of pinion height adjusting washer according to the procedure for bringing the drive pinion close to the driven gear.
• Heel contact (outside end contact)
Check item: Teeth contact area is too small.
Contact pattern
