Shim selection steps:
●
To find the final drive pinion gear shim
thickness “A”, use the following formula.
a
= a numeral (usually a decimal number)
on the final drive pinion gear either
added to or subtracted from “84”
b
= a numeral (usually a decimal number)
on the final gear case either added to
or subtracted from “83”
Example:
1) If “01” is stamped on the final drive
pinion gear,
a
= 84 + 0.01 = 84.01
2) If “50” is stamped on the final gear
case,
b
= 83 + 0.50 = 83.50
3) Therefore, “A” is 0.51.
“A”= 84.01 – 83.50
= 0.51
4) Round off the hundredth digit and
select 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 hun-
dredth place. Thus, the shim thick-
ness is 0.50 mm.
