Primary Shaft Preload Adjustment

Primary Shaft Preload Adjustment





1. Install the primary shaft bearing races into the clutch housing.
2. Set the bearing race into the SST (selector) as shown in the figure.

Note: Turn the selector to eliminate the gap indicated by the arrow in the figure.





3. Set the SST (selector) for the primary shaft in the clutch housing. Mount the shaft gear assemblies as shown in the figure.





4. Set the SST (collars) in the positions shown in the figure.





5. Install the transaxle case and tighten the SST (bolts) to the specified torque.

Tightening torque:
37.3 - 52.0 N-m (3.9 - 5.3 kgf-m, 27.6 - 38.3 ft-lbf)





6. To seat the bearing, mount the SST (bars) on parts A and B of the selector, and turn the selector so the gap is widened. Then turn the SST in the reverse direction until the gap is eliminated.





7. Manually expand the selector until it no longer turns by hand.





8. Use a feeler gauge to measure the gap in the SST (selector).

Caution: Measure the gap around the entire circumference of the selector.

9. Take the maximum reading and determine the shim to used as follows.
^ Select the thinnest allowable shim from the table to obtain standard clearance.

Tightening amount:
0 - 0.05 mm (0 - 0.002 in)

Example:
Reading from step 8: 0.57 mm (0.022 in)

Shim selecting range:
(0.57 mm (0.022 in) + 0 mm (0 in)-(0.57 mm (0.022 in) + 0.05 mm (0.002 in) = 0.57 mm (0.022 in)-0.62 mm (0.024 in)

Shim:
0.60 mm (0.024 in)

Primary shaft gear adjust shim size (mm (in))





10. Remove the transaxle case and the SST.
11. Remove the selector and primary shaft component.





12. Remove the bearing race.
13. Install the adjustment shim(s) and install the bearing race using the SST.

Caution: Use the adjustment shim(s) selected during bearing preload adjustment.

14. Set the primary shaft gear component into the clutch housing.
15. Install the transaxle case, and tighten to the specified torque.

Tightening torque:
37.3 - 52.0 N-m (3.9 - 5.3 kgf-m, 27.6 - 38.3 ft-lbf)





16. With the transaxle facing in the direction shown in the figure, install the SST to the primary shaft gear component.
17. Verify that the preload is within the specification.
^ If not within the specification, return to Step 1.

Primary shaft gear preload:
0.12 - 0.39 N-m (1.2 - 4.0 kgf-cm, 1.05 - 3.47 in-lbf)

18. Remove the SST.
