Calculate dimension "N" (thickness of adjusting shim) using the following procedure to satisfy specification of end play for differential side bearing.
End play: 0.15 - 0.21 mm (0.0059 - 0.0083 in) Dimension "N" = ("N 1" - "N2") + End play

"N": Thickness of adjusting shim

"N1": Distance between clutch housing case end face and mounting face of adjusting shim

"N2": Distance between differential side bearing and transaxle case

Use the "Available Shims" table for the available shim sizes. Refer to . "AVAILABLE SHIMS - DIFFERENTIAL SIDE BEARING PRELOAD AND ADJUSTING SHIM ".
1. Using dial gauge and scale, measure dimension "N1" between clutch housing case end face and mounting face of adjusting shim.
2. Install outer race onto differential side bearing on final gear side. Holding the outer race horizontally by hand, rotate the final gear five times or more (for smooth movement of bearing roller).

Measure the turning torque of the final drive assembly using Tool.
Turning torque of: 2.9 - 6.9 N-m (30 - 70 kg-cm, final drive assembly 26 - 61 in-lb)

(New bearing)

- When the old bearing is used again, turning torque will be slightly less than the above.
- Make sure turning torque is close to the specified range.
- Changes in turning torque of final drive assembly per revolution should be within 1.0 N-m (10 kg-cm, 8.7 in-lb) without binding.
Calculate dimension "O" (thickness of adjusting shim) using the following procedure to satisfy specification of end play for input shaft rear bearing.
End play: 0 - 0.06 mm (0 - 0.0024 in)

Dimension "O" = ("O1" - "O2") + End play

"O": Thickness of adjusting shim

"O1": Distance between transaxle case end face and mounting face of adjusting shim

"O2": Distance between clutch housing case end face and end face of input shaft rear bearing
