a. Position the middle gears with the appropri-
ate shim(s) that has had its respective thick-
ness calculated from information marked on
the crankcase and middle driven pinion gear.
b. To find middle drive pinion gear shim thick-
ness “A”, use the following formula.
“a”= 65.00
“b”= 18.94
“c”= a numeral on the lower crankcase, to be
divided by 100 and added to “84”
Example:
“a” is 65.00
“b” is 18.94
If the lower crankcase is marked “45”
“c” is 84.45 (i.e., 84.00 + 0.45 = 84.45)
“A” = 84.45 - 65.00 - 18.94 = 0.51
Round off to the hundredths digit and select
the appropriate shim(s).
TIP
In the above example, the calculated number is
0.51. The chart instructs you to round off the 1 to
0. Thus, the shim thickness is 0.50 mm.
Shims are supplied in the following thickness-
es.
c. To find middle driven pinion gear shim thick-
ness “B”, use the following formula.
“d” = a numeral on the middle driven pinion
gear, to be divided by 100 and either added
to or subtracted from “34”
“e” = Measured value
“f” = a numeral on the lower crankcase, to be
divided by 100 and added to “87”.
Example:
If the middle driven pinion gear is marked “-
03”
“d” is 33.97 (i.e., 34.00 + (- 0.03) = 33.97)
“e” is 54.49
If the lower crankcase is marked “95”
“f” is 87.95 (i.e., 87.00 + 0.95 = 87.95)
“B” = 33.97 + 54.49 - 87.95 = 0.51
Round off to the hundredths digit and select
the appropriate shim(s).
