= numeral (usually decimal num-
ber) on the bearing housing is either added to or substracted from "76"illnumeral (usually decimal number) on the middle driven pinion gear is either added to or substracted from "59"= numeral (usually decimal number) on the middle driven pinion gear is either added to or substracted from "79.5"fi)numeral (usually decimal number) on the left crankcase specifies thickness of "94.3"CDnumeral (usually decimal number) on the right crankcase specifies thickness of "1.3"Example: 1) If the bearing housilig is marked "-15" is 75.85 2) If the driven pinion gear is marked "+02" ill is 59.02 3) Ifthe driven pinion gear is marked "+02" is 79.52 4) If the crankcase (left) is marked "94.31" (fi) is 94.31 5) Ifthe crankcase (right) is marked "1.36" CD is 1.36 6) Therefore, the shim thickness is 0.63 mm
