SHAFT DRIVE
Since the final drive pinion gear shims are only
available in 0.10 mm increments, round off to
the hundredths digit.
In the example above, the calculated final
drive pinion gear shim thickness is 0.51 mm.
The chart instructs you to round off the 1 to 0.
Thus, you should use a 0.50 mm final drive
pinion gear shim.

c. To find ring gear shim thickness “B”, use the
following formula:
Where:
c
= a numeral on the final drive housing, to be
divided by 100 and added to “45”.
d
= a numeral usually on the outside of the
ring gear bearing housing, to be divided by 100
and added to “3”.
e
= a numeral (positive or negative) on the
inside of the ring gear, to be divided by 100
and added to “35.40”.
f
= the ring gear bearing thickness constant.
