To find the final drive pinion gear shim
thickness "A", use the following formula.
Final drive pinion gear shim thickness:
"A" = a – b
a = a numeral (usually a decimal number)
b = a numeral (usually a decimal number)
Example:
1) If "01" is stamped on the final drive
2) If "50" is stamped on the final gear case,
3) Therefore, "A" is 0.51.
4) Round off the hundredth digit and select

on the final drive pinion gear either
added to or subtracted from "84"
on the final gear case either added to or
subtracted from "83"
pinion gear,
a = 84 + 0.01 = 84.01
b = 83 + 0.50 = 83.50
"A"= 84.01 – 83.50
= 0.51
the appropriate shim(s).
In the example above, the calculated
number is 0.51. The chart instructs you
to round off 1 to 0 at the hundredth
place. Thus, the shim thickness is
0.50 mm.
