Differential: Service and Repair

DISASSEMBLY





1. Using Special Tool (A): 09913-65810 and (B): 09925-88210, or equivalent, remove R bearing.
2. Take out speedometer drive gear.

NOTE: In case that half-moon type puller is used with press for bearing removal, remove final gear in advance.

3. Remove L bearing by using puller while supporting its center shaft as described above.
4. Support differential case with soft jawed vise and remove 8 final gear bolts then take out final gear.





5. Using Special Tool (C): 09922-85811 (4.5 mm), or equivalent and hammer, drive out differential side pinion shaft pin and then disassemble component parts.

ADJUSTMENT AND REASSEMBLY
Judging from abnormality noted before disassembly and what is found through visual check of component parts after disassembly, prepare replacing parts and proceed to reassembly. Make sure that all parts are clean.
1. Assemble differential gear and using Special Tool (A): 09900-20606 and (B): 09900-20701, or equivalent measure thrust play of differential gear as follows.

Differential gear thrust play: 0.05 - 0.33 mm (0.002 - 0.013 inch)





Left Side
- Hold differential assembly with soft jawed vise and apply measuring tip of dial gauge to top surface of gear.
- Using 2 screwdrivers, move gear up and down and read movement of dial gauge pointer.





Right Side
- Using similar procedure to the above, set dial gauge tip to gear shoulder.
- Move gear up and down by hand and read dial gauge.





2. If thrust play is out of specification, select suitable thrust washer from among following available size, install it and check again that specified gear play is obtained.





3. Drive in spring pin from right side till it is flush with differential case surface.
4. Press-fit L bearing by using special tool and copper hammer.
5. Install speedometer drive gear, support differential assembly as illustrated so as to L bearing is floating, and then press-fit R bearing like L bearing in Step 4.





6. Hold differential assembly with soft jawed vise, install final gear and then tighten it with 8 bolts to specified torque.
Tightening Torque (a): 90 Nm (65.0 ft. lbs.)

CAUTION: Use of any other bolts than specified ones is prohibited.
