To find the ring gear shim thickness "B", use
the following formula.
Ring gear shim thickness:
"B" = c + d – (e + f)
c = a numeral (usually a decimal number)
d = a numeral (usually a decimal number)
e = a numeral (usually a decimal number)
f = bearing thickness (considered constant)
Example:
1) If "53" is stamped on the final gear case,
2) If "05" is stamped on the ring gear
3) If "– 05" is stamped on the ring gear,
4) f = 11.00.
