Transmission Adjustment (1)

ASSEMBLY


Adjustment (1) (For HR16DE Engine Models)


REDUCTION PINION GEAR BEARING PRELOAD
1. Select proper thickness of reduction pinion gear adjusting shim using the following procedures.





a. Place reduction pinion gear on transaxle case as shown.
b. Install idler gear bearing outer race on transaxle case.





c. Place idler gear bearing inner race on outer race.
d. Measure dimensions (B), (C) and (D), and calculate dimension
(A).










- Measure dimension (B) between the end of reduction pinion gear and the surface of transaxle case.
- Measure dimension (B) in at least two places, and take the average.





- Measure dimension (C) between the surface of idler gear bearing inner race and the surface of transaxle case.
- Measure dimension (C) in at least two places, and take the average.





- Remove reduction pinion gear from transaxle case.
- 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, and take the average.
- Calculate dimension (A).

A = D - (B + C)






e. Measure dimension (E) between the end of idler gear and idler gear bearing inner race mating surface of idler gear.
- Measure dimension (E) in at least two places, and take the average.
f. Select proper thickness of reduction pinion gear adjusting shim. Adjusting Shims, Needle Bearings, Thrust Washers And Snap Rings for reduction pinion gear adjusting shim selection.










2. Install reduction pinion gear and reduction pinion gear adjusting shim selected in step 1-f on transaxle case.

CAUTION:
Apply ATF to reduction pinion gear bearing.
3. Press idler gear bearing inner race on idler gear.
4. Press idler gear on reduction pinion gear using Tool.

Tool number : ST35271000 (J-26091)

CAUTION:
- Apply ATF to idler gear bearing.
- Press idler gear until idler gear fully contacts reduction pinion gear bearing adjusting shim.
5. Set manual shaft in "P" position to lock idler gear.
6. Tighten lock nut of idler gear to the specified torque. Component.

CAUTION:
Lock idler gear with parking pawl when tightening lock nut.





7. Measure turning torque of reduction pinion gear using Tool.






- When measuring turning torque, turn reduction pinion gear in both directions several times to seat bearing rollers correctly.
- If turning torque is out of specification, decrease or increase thickness of reduction pinion gear adjusting shim.

OUTPUT SHAFT BEARING PRELOAD
1. Select proper thickness of output gear adjusting spacer using the following procedures.





a. Remove paper rolled around output shaft.
b. Install output gear bearing outer race on bearing retainer.
c. Place bearing retainer on output shaft.





d. Place output gear bearing inner race on bearing retainer.
e. Measure dimensions (G) and (H), and calculate dimension (F).










- Measure dimension (G) between end of output shaft and surface of output gear bearing inner race.
- Measure dimension (G) in at least two places, and take the average.





- Measure dimension (H) between end of output shaft and adjusting spacer mating surface of output shaft.
- Measure dimension (H) in at least two places, and take the average.
- Calculate dimension (F).

F = H - G





f. Measure dimension (I) between end of output gear (adjusting spacer mating surface) and output gear bearing inner race surface.
- Measure dimension (I) in at least two places, and take the average.
g. Select proper thickness of output gear adjusting spacer. Refer to "Parts Information" for output gear adjusting spacer selection.










2. Install bearing retainer (1) in transaxle case.
3. Tighten bearing retainer bolts to the specified torque.





4. Install output shaft (1) and output gear adjusting spacer (2) selected in step 1-f on transaxle case.

CAUTION:
- Apply ATF to output shaft bearing.
- Do not force output shaft to install or seal ring may be damaged.
5. Press output gear bearing inner race on output gear (3).
6. Set Tool (A) on output gear (3), and press output gear (3) on output shaft (1).

CAUTION:
- Apply ATF to output gear bearing.
- Do not pinch seal ring when output shaft is pressed in.
- Press output gear (3) until output gear (3) fully contacts output gear adjusting space (2).

Tool number : ST35271000 (J-26091)

7. Set manual shaft in "P" position to lock idler gear.
8. Tighten lock nut of output gear to the specified torque. Component.

CAUTION:
- Do not reuse lock nut.
- Lock idler gear with parking pawl when tightening lock nut.





9. Remove idler gear (1) using Tool (A) to measure output shaft bearing preload.

Tool number : ST27180001 (J-25726-A)






10. Measure turning torque of output shaft using Tool.






- When measuring turning torque, turn output shaft in both directions several times to seat bearing rollers correctly.
- If turning torque is out of specification, decrease or increase thickness of output gear adjusting spacer.
11. Press idler gear on reduction pinion gear.





12. Tighten lock nut (1) of idler gear to the specified torque. Component.
13. After properly adjusting turning torque, clinch lock nuts (1) of idler gear and output gear as shown.










14. Install side cover gasket and side cover on transaxle case.

CAUTION:
- Do not reuse side cover gasket.
- Completely remove all moisture, oil and old gasket, etc. from the transaxle case and side cover mating surfaces.
15. Tighten side cover bolts (1) to the specified torque. Component.
