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




- Measure dimension "B" between the end of reduction 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 gear and the adjusting shim mating surface of reduction 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 gear bearing adjusting shim using Specifications table as a guide.

T = A - E

Reduction gear bearing adjusting shim: Refer to Specifications.




3. Install reduction gear and reduction 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 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 gear.
- When measuring turning torque, turn reduction gear in both directions several times to seat bearing rollers correctly.

Turning torque of reduction gear: 0.11 - 0.69 N.m (1.1 - 7.0 kg-cm, 0.95 - 6.08 in-lb)




8. After properly adjusting turning torque, clinch idler gear lock nut as shown (only RL4F03V).

F = H - G




e. Measure distance "I" between end of output gear (adjusting spacer mating surface) and bearing inner race fitting surface.
f. Calculate dimension "T(2)".
- "T(2)": Distance between adjusting spacer mating surface of output gear and output shaft
T(2) = F - I

g. Select proper thickness of output shaft bearing adjusting spacer using Specifications table as a guide.
Output shaft bearing adjusting spacer: Refer to Specifications.
