Therefore, "A" is 1.40.
"A" = 9.01 + 64.97 - 17.0 - 55.0 - 0.58 = 1.40
Round off hundredths digit and select appro-
priate shim(s).
In the above example, the calculated shim
thickness is 1.40 mm. The following chart in-
structs you, however, to round off 0 to 0.

Shims are supplied in the following thickness-
es.
Middle drive pinion gear shim
Thickness (mm)
0.50 0.55 0.60 0.70 0.80 0.90 1.00
c. To find middle driven pinion gear shim thick-
ness "B", use the following formula.
Middle driven pinion gear shim thickness
"B" = "f" - "g" + "h" - "i" - "j" - 0.05
"f" = a numeral (usually a decimal number) on
the bearing housing is either added to or sub-
tracted from "77.5"
TIP
After replacing any part in the middle driven pin-
ion gear assembly, the overall length of the as-
sembly will change. Therefore, be sure to
measure distance "f" to select the correct middle
driven pinion gear shim thickness.

MIDDLE GEAR
f
"g" = a numeral (usually a decimal number)
on the middle driven pinion gear is either add-
ed to or subtracted from "49.0"
"h" = a numeral (usually a decimal number)
on the middle driven pinion gear is either add-
ed to or subtracted from "80.5"
"i" = a numeral (usually a decimal number) on
the left crankcase specifies a thickness of
"99.98"
"j" = a numeral (usually a decimal number) on
the right crankcase specifies a thickness of
"8.12"
Example:
If the bearing housing is marked "+03",
"f" is 77.53
If the driven pinion gear is marked "+0",
"g" is 49.0
If the driven pinion gear is marked "-10",
"h" is 80.40
