a. Position the final drive pinion gear and the
ring gear with shims
1
and
2
. Calculate
the respective thicknesses from information
marked on the final drive housing and the
drive pinion gear.

b. To find final drive pinion gear shim thickness
“A”, use the following formula:
Where:
a
= a numeral (positive or negative) on the
ring gear, to be divided by 100 and added to
“84”.
b
= a numeral on the final drive housing, to be
divided by 100 and added to “83”.
Example:
If the final drive pinion gear is marked “+01”
and the final drive housing is marked “50”:
A = (84 + 1/100) – (83 + 50/100)
= (84 + 0.01) – (83 + 0.50)
= 84.01 – 83.50
= 0.51
Therefore, the calculated final drive pinion
gear shim thickness is 0.51 mm. Shim sizes
are supplied in the following thicknesses.
