- 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 pin ion gear bearing adjusting shim using image as a guide.
T = A - E
Reduction pinion gear bearing adjusting shim: Refer to image.
3. Install reduction pinion gear and reduction pinion gear bearing adjusting shim selected in step 2-e on transmission case.
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: 0.11 - 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 "e1," and "e2" at side cover and then calculate dimension "A".
- Measure dimension "e1," and "e2" in at least two places.
"A": Distance between transmission case fitting surface and adjusting shim mating surface.
A= e1, - e2 e2: Height of gauge
5. Measure dimensions "e2" and "e3" and then calculate dimension "B".
- Measure "e2" and "e3" 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 = e2 - e3 e2: 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.
