8. Check the clearance between rear companion flange and main shaft during pushing the bolt (A) at direction.
9. Use the formula below to calculate adjusting shim thickness.
CAUTION:
Adjusting shim thickness is in step of 0.1 mm. When a calculation result includes the second dec-
imal place, it must be rounded down.
10. Select the proper adjusting shim. For selecting adj usting shim, refer to the latest parts information.

Shim selection equation:
T = T
0 + (C − 0.1)
T: Correct shim thickness
T
0: The thinnest shim thickness
C: Measured clearance between rear companion flange and main shaft
Example:
T = 2.1 + (0.34 − 0.1) = 2.34
T
0:2.1
C: 0.34
Caluculated value... T = 2.34 mm
Used shim... T = 2.3 mm
