e = a numeral (usually a decimal number) on the left crankcase specifies a thickness of Example: 1) If the bearing housing is marked “–02”, ..... a is 0.58 2) b is 17.0 3) c is 55.0 4) If the right crankcase is marked “64.97”, ..... d is 64.97 5) If the left crankcase is marked “9.01”, ..... e is 9.01 6) Therefore, the shim thickness is 1.40 mm. “A” = 9.01 + 64.97 – 17.0 – 55.0 – 0.58 = 1.40 7) Round off hundredths digit and select appropriate shim(s). In the example above, the calculated shim thickness is 1.40 mm. The chart instructs you, however, to round off 0 to 0. e Shims are supplied in the following thickness.
