Model RS5F50A

DISASSEMBLY
1. Remove final gear.
2. Remove speedometer drive gear by cutting it.
3. Press out differential side bearings. 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, viscous coupling, side gears and pinion mate gears.
- Check washers for wear.





Viscous Coupling
- Check case for cracks.
- Check silicone oil for leakage.





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





ASSEMBLY
1. Attach side gear thrust washers to side gears, then install pinion mate washers and pinion mate gears in place.





2. Insert pinion mate shaft. When inserting, be careful not to damage pinion mate thrust washers.





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 thick ness of side gear thrust washers.





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





5. Install final gear.
6. Install speedometer drive gear.





7. Press on differential side bearings.
