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

Turning torque of final drive assembly
(New bearing):

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.

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
