b. To find final drive pinion gear shim thickness
“A”, use the following formula:
Where:
a = 85.00
b = a numeral on the final gear case, to be di-
vided by 100 and added to “84”.
Example:
If the final gear case is marked “52”:
Round off to the hundredths digit and select
the appropriate shim(s).
TIP
In the example above, the calculated final drive
pinion gear shim thickness is 0.28 mm (0.011
in). The chart instructs you to round off the 8 to
10. Thus, you should use a 0.30 mm (0.012 in)
final drive pinion gear shim.
Shim sizes are supplied in the following thick-
nesses.
c. To find ring gear shim thickness “B”, use the
following formula:
Where:
c = a numeral on the final gear case, to be di-
vided by 100 and added to “52”.
d = a numeral indicated by the punch mark on
the ring gear bearing housing, to be divided
by 100 and added to “1”.
e = a numeral (positive or negative) on the in-
side of the ring gear, to be divided by 100 and
added to “38.50”.
f = the bearing thickness constant.
Example:
If the final drive housing is marked “97”, the
ring gear bearing housing is marked “03”, the
ring gear is marked “- 08”, and “f” is 13.00:
Round off the hundredths digit and select ap-
propriate shim(s).
Final drive pinion gear shim thickness
A = a - b - 0.2
A = 85.00 - (84 + 52/100) - 0.2
= 85.00 - (84 + 0.52) - 0.2
= 85.00 - 84.52 - 0.2
= 0.28

= (52 + 0.97) - (1 + 0.03) -
(38.50 - 0.08) - 13.00
= 52.97 - 1.03 - 38.42 - 13.00
