Tooth Contact Of Hypoid Driven Gear
- Adjust until correct teeth contact is obtained.
- Check tooth contact, and perform the adjustment as follows.
- Correct tooth contact
Check item: Tooth contact surface is slightly shifted toward the side under a no-load condition. (When driving, it moves towards the heel side.)
- Face contact
Check item: Backlash is too large .
Contact pattern
Corrective action: Tighten the differential side retainer to move the driven gear closer to the drive pinion shaft.
- Flank contact
Check item: Backlash is too small .
Contact pattern
Corrective action: Loosen the differential side retainer to move the driven gear away from the drive pinion shaft.
- Toe contact (inside contact)
Check item: Teeth contact area is too small .
Contact pattern
Corrective action: Increase the thickness of drive pinion shim and tighten the differential side retainer to move the driven gear closer to the drive pinion shaft according to the procedure for bringing drive pinion shaft away from the driven gear.
- Heel contact (outside end contact)
Check item: Teeth contact area is too small .
Contact pattern
Corrective action: Reduce the thickness of drive pinion shim and loosen the differential side retainer to move the driven gear away from the drive pinion shaft according to the procedure for bringing drive pinion shaft closer to the driven gear.
