8. Select proper thickness of differential side bearing adjusting shim(s) using SDS table as a guide.
Differential side bearing adjusting shim: Refer to DIFFERENTIAL SIDE BEARING ADJUSTING SHIMS.





9. Remove converter housing from transmission case.
10. Remove final drive assembly from transmission case.
11. Remove differential side bearing outer race from transmission case.
12. Reinstall differential side bearing outer race and shim(s) selected from SDS table on transmission case.
13. Reinstall converter housing on transmission case and tighten transmission case fixing bolts to the specified torque.





14. Insert Tool into differential case and measure turning torque of final drive assembly.
^ Turn final drive assembly in both directions several times to seat bearing rollers correctly.
Turning torque of final drive assembly (New bearing): 0.49 - 1.08 Nm (5.0 - 11.0 kg-cm, 4.3 - 9.5 inch lbs.)
^ When old bearing is used again, turning torque will be slightly less than the above.
^ Make sure torque is within the specified range.

REDUCTION PINION GEAR BEARING PRELOAD





^ Be sure to remove final drive assembly before doing this procedure.
^ Using caliper and straightedge, calculate a dimension T (adjuster shim thickness) using the following formula. Adjust the inspection standard for preload (rotating slide torque) as shown below.
T = A - E
Inspection standard for preload: 0.1 - 0.69 Nm (1.1 - 7.0 kg-cm, 0.95 - 6.08 inch lbs.)





1. Remove transmission case and final drive assembly from converter housing.
2. Select proper thickness of reduction pinion gear bearing adjusting shim using the following procedures.
a. Place reduction pinion gear on transmission case as shown.





b. Place idler gear bearing on transmission case.
c. Measure dimensions B, C and D and calculate dimension A.
A = D - (B + C)
A: Distance between the surface of idler gear bearing inner race and the adjusting shim mating surface of reduction pinion gear.





^ Measure dimension B between the end of reduction pinion gear and the surface of transmission case.
^ Measure dimension B in at least two places.





^ Measure dimension C between the surface of idler gear bearing inner race and the surface of transmission case.
^ Measure dimension C in at least two places.





^ Measure dimension D between the end of reduction pinion gear and the adjusting shim mating surface of reduction pinion gear.
^ Measure dimension D in at least two places.
^ Calculate dimension A.
A = D - (B + C)





d. Measure dimension E between the end of idler gear and the idler gear bearing inner race mating surface of idler gear.
^ Measure dimension E in at least two places.
e. Calculate T and select proper thickness of reduction pinion gear bearing adjusting shim using SDS table as a guide.
T = A - E - 0.05 mm (0.0020 inch)*
Reduction pinion gear bearing adjusting shim: Refer to REDUCTION PINION GEAR BEARING ADJUSTING SHIMS.
*: Bearing preload





3. Install reduction pinion gear and reduction pinion gear bearing adjusting shim selected in step 2-e on transmission case using Tool.
4. Press idler gear bearing inner race on idler gear.
5. Press idler gear on reduction pinion gear.
^ Press idler gear so that idler gear can be locked by parking pawl.





6. Tighten idler gear lock nut to the specified torque.
^ Lock idler gear with parking pawl when tightening lock nut.





7. Measure turning torque of reduction pinion gear.
^ When measuring turning torque, turn reduction pinion gear in both directions several times to seat bearing rollers correctly.
Turning torque of reduction pinion gear: 0.1 - 0.69 Nm (1.1 - 7.0 kg-cm, 0.95 - 6.08 inch lbs.)

OUTPUT SHAFT END PLAY





^ Measure clearance between side cover and the end of the output shaft bearing.
^ Select proper thickness of adjusting shim so that clearance is within specifications.





1. Install bearing retainer for output shaft.





2. Install output shaft thrust needle bearing on bearing retainer.





3. Install output shaft on transmission case.





4. Measure dimensions I1 and I2 at side cover and then calculate dimension A.
^ Measure dimension I1 and I2 in at least two places
A: Distance between transmission case fitting surface and adjusting shim mating surface
A = I1 - I2
I2: Height of gauge





5. Measure dimensions I2 and I3 and then calculate dimension B.
Measure I2 and I3 in at least two places.
B: Distance between the end of output shaft bearing outer race and the side cover fitting surface of transmission case
B = I2 - I3
I2: Height of gauge





6. Select proper thickness of adjusting shim so that output shaft end play (clearance between side cover and output shaft bearing) is within specifications.
Output shaft end play (A - B): 0 - 0.5 mm (0 - 0.020 inch)
Output shaft end play adjusting shim: Refer to OUTPUT SHAFT END PLAY ADJUSTING SHIMS.
7. Install adjusting shim on output shaft bearing.





8. Apply locking sealant (Loctite 5/8 or equivalent) to transmission case as shown in illustration.





9. Install side cover on transmission case.
