14. Measure turning torque of final drive assembly using Tool.
Tool number (J-39713)
NOTE:
^ Turn the final drive assembly in both directions several times to seat the bearing rollers correctly
Turning torque of final drive assembly (New bearing): 0.78 - 1.54 Nm (8.0 - 15.7 kgf-cm, 6.9 - 13.6 inch lbs.)
^ When old bearing is being used again, turning torque will be slightly less than above.
^ Make sure torque is close to the specified range.
REDUCTION PINION GEAR BEARING PRELOAD
1. Remove transaxle case and final drive assembly from converter housing.
2. Select proper thickness of reduction pinion gear bearing adjusting shim using the procedures.
a. Place reduction pinion gear on transaxle case as shown.
b. Place idler gear bearing on transaxle 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 transaxle case using straightedge and depth gauge.
NOTE: Measure dimension "B" in at least two places.
^ Measure dimension "C" between the surface of idler gear bearing inner race and the surface of transaxle case using straightedge and depth gauge.
NOTE: 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 using straightedge and depth gauge.
NOTE: 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 using depth gauge.
NOTE: Measure dimension "E" in at least two places.
e. Select proper thickness of reduction pinion gear bearing adjusting shim.
Proper shim thickness = A - E - 0.05 mm (0.0020 inch)*
(*: Bearing preload)
Reduction pinion gear bearing adjusting shim: Refer to "REDUCTION PINION GEAR BEARING ADJUSTING SHIMS".
3. Install reduction gear and reduction gear bearing adjusting shim selected in step 2-e on transaxle case.
4. Press idler gear bearing inner race on idler gear.
5. Install idler gear on reduction gear using Tool.
Tool number: ST35271000 (J-26091)
NOTE: Press idler gear until idler gear fully contacts adjusting shim.
6. Tighten idler gear lock nut to the specified torque using suitable tool. Refer to "Components".
NOTE: Lock idler gear with parking pawl when tightening the lock nut.
7. Measure turning torque of reduction pinion gear using Tool.
Tool number: ST3127S000 (J-25765-A)
NOTE: When measuring turning torque, turn the reduction pinion gear in both directions several times to seat bearing rollers correctly.
Turning torque of reduction pinion gear: 0.05 - 0.39 Nm (0.5 - 4.0 kgf-cm, 0.43 - 3.47 inch lbs.)
NOTE: If turning torque is out of specification, select the correct reduction pinion gear adjusting shim.
8. After properly adjusting turning torque, clinch idler gear lock nut as shown.
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 using suitable tool.
2. Install output shaft thrust needle bearing on bearing retainer.
3. Install output shaft on transaxle case.
4. Measure dimensions "l1" and "l2" at side cover and then calculate dimension "A" using straightedge and depth gauge.
Measure dimension "l1" and "l2" in at least two places.
"A": Distance between transaxle case fitting surface and adjusting shim mating surface.
A = l1 - l2:
l2: Height of gauge
5. Measure dimensions "l2" and "l3" and then calculate dimension "B" using straightedge and depth gauge.
