a. To find the final drive pinion gear shim thick-
ness “A”, use the following formula.
a
= 92.5 mm
b
= a numeral (usually a decimal number) on
the final drive pinion gear bearing housing
either added to or subtracted from “34”
c
= a numeral (usually a decimal number) on
the final drive pinion gear bearing housing
either added to or subtracted from “55”
d
= a numeral (usually a decimal number) on
the final gear case either added to or sub-
tracted from “112”
Example:
1)
a
= 92.5
2) If “98” is stamped on the final drive pinion
gear bearing housing,
b
= 34 + 0.98
= 34.98
3) If “48” is stamped on the final drive pinion
gear bearing housing,
c
= 55 + 0.48
= 55.48
4) If “03” is stamped on the final gear case,
d
= 112 + 0.03
= 112.03
5) Therefore, “A” is 0.97.
“A” = 92.5 + (55.48 – 34.98) – 112.03
= 0.97
6) Round off the hundredth digit and select the
appropriate shim(s).
In the example above, the calculated num-
ber is 0.97. The chart instructs you to round
off 7 to 5 at the hundredth place. Thus, the
shim thickness is 0.95 mm.

“A” =
