Final Drive

DISASSEMBLY





1. Remove final gear.
2. Remove speedometer drive gear by cutting it.





3. Press out differential side bearings with Tool.
- Be careful not to mix up the right and left bearings.





4. Drive out retaining pin and draw out pinion mate shaft.
5. Remove pinion mate gears and side gears.

INSPECTION
Gear, washer, shaft and case





- Check mating surfaces of differential case, side gears and pinion mate gears.
- Check washers for wear.

Bearing





- Make sure bearings roll freely and are free from noise, cracks, pitting and wear.
- When replacing tapered roller bearing, replace outer and inner race as a set.

ASSEMBLY
1. Install side gear and thrust washers in differential case.





2. Install pinion mate gears and thrust washers in differential case while rotating them.
- When inserting, be careful not to damage pinion mate thrust washers.
- Apply gear oil to gears, shafts, synchronizers; and bearings when assembling.
3. Measure clearance between side gear and differential case with washers following the procedure below:





a. Set Tool and dial indicator on side gear.





b. Move side gear up and down to measure dial indicator deflection. Always measure indicator deflection on both side gears.
Clearance between side gear and differential case with washers: 0.1 - 0.2 mm (0.004 - 0.008 inch)
c. If not within specification, adjust clearance by changing thickness of side gear thrust washers.
Side gear thrust washer: Refer to Specifications.





4. Install retaining pin.
- Make sure that retaining pin is flush with case.





6. Install final gear.
- Apply locking sealant to final gear fixing bolts before installing.
7. Install speedometer drive gear.





8. Press on differential side bearings.
