To find the ring gear shim thickness "B", use
the following formula.
Ring gear shim thickness
e = a numeral (usually a decimal number) on
f = a numeral (usually a decimal number) on
g = a numeral (usually a decimal number) on
h = bearing thickness (considered constant)
Example:
1) If "98" is stamped on the final gear case,
2) If "55" is stamped on the ring gear bearing
3) If "–05" is stamped on the ring gear,
4) h = 14.00
5) Therefore, shim thickness "B" is 0.48.

"B" = e – f – (g + h)
the final gear case either added to or sub-
tracted from "50"
the outside of the ring gear bearing hous-
ing and added to "1"
the inside of the ring gear either added to
or subtracted from "35"
Bearing thickness h
14.00 mm
e = 50 + 0.98
= 50.98
housing,
f = 1 + 0.55
= 1.55
g = 35 – 0.05
= 34.95
"B" = 50.98 – 1.55 – (34.95 + 14.00)
= 49.43 – 48.95
= 0.48
