side. Holding lightly the outer race horizontally by hand, rotate

5. Measure turning torque of final drive assembly.
Turning torque of final drive assembly
(New bearing):
2.9 - 6.9 N´m (30 - 70 kg-cm, 26 - 61 in-lb)
+When old bearing is used again, turning torque will be
slightly less than the above.
+Make sure 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.

6. Calculate dimension ªOº (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 ªOº = (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
Input shaft rear bearing adjusting shims:
Refer to SDS, MT-127.
