To find the final drive pinion gear shim thick-

ness "A", use the following formula.
Final drive pinion gear shim thickness

a = 92.5 mm
a
b = a numeral (usually a decimal number) on
c = a numeral (usually a decimal number) on
d = a numeral (usually a decimal number) on
Example:
1) a = 92.5
2) If "98" is stamped on the final drive pinion
3) If "48" is stamped on the final drive pinion
4) If "03" is stamped on the final gear case,
5) Therefore, "A" is 0.97.

c = 55 + 0.48

d = 112 + 0.03
= 112.03
"A" = 92.5 + (55.48 – 34.98) – 112.03
= 0.97
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.
