0.05 ~ 0.12 mm.

7. Measure:
• crankcase-to-middle-driven-shaft-bearing-
housing clearance (with a thickness gauge)
8. Select:
• shim(s) 1
a. Shims can only be selected in 0.05 mm
increments, therefore round off to the hun-
dredth's digit of the calculated thickness
and select the appropriate shim(s) with the
following chart.
b. For example, the clearance between the
crankcase and the middle driven shaft bear-
ing housing is 0.46 mm. Therefore, the
chart instructs you to round off the 6 to 5.
Thus, you should use one 0.15 mm and one
0.30 shim.
