Differential Thrust Clearance Adjustment

Special Tools Required 

Driver Handle, 40 mm I.D. 07746-0030100

1. Remove the transmission housing side differential oil seal (see OIL SEAL REPLACEMENT ).
2. If you removed the 80 mm shim (A) from the transmission housing, reinstall the same sized shim.

4. Install the transmission housing onto the clutch housing, then tighten the 8 mm flange bolts in a crisscross pattern in several steps (see step 16 on GEARSHIFT MECHANISM REPLACEMENT ).

   Specified Torque: 8 x 1.25 mm 27 IMm (2.8 kgf-m, 20 Ibf ft) 

5. Use the 40 mm I.D. driver handle (A) to bottom the differential assembly in the clutch housing.

6. Measure the clearance between 80 mm shim and the bearing outer race in the transmission housing.

   Standard: 0-0.10 mm (0.00-0.0039 in)

7. If the clearance exceeds the standard, select a new 80 mm shim from the following table. If the clearance measured in step  6 is within the standard, go to step  10.

8. Remove the bolts and the transmission housing.
9. Replace the thrust shim selected in step  7, then recheck the clearance.
10. Install a new transmission housing side differential oil seal (see OIL SEAL REPLACEMENT ).
11. Reinstall the transmission housing.
