    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.

    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
