ALIGNING THE FINAL DRIVE PINION GEAR
AND RING GEAR
T
IP
Aligning the final drive pinion gear and ring gear
is necessary when any of the following parts are
replaced:
• Final drive case
• Ring gear bearing housing
• Any bearing
1. Select:
• Final drive pinion gear shim(s) “1”
• Ring gear shim(s) “2”

a. Position the final drive pinion gear shim(s)
and the ring gear with shim(s). Calculate the
respective thicknesses from information
marked on the final drive case, ring gear
bearing housing, and ring gear.
b. To find final drive pinion gear shim thickness
“A”, use the following formula:
Where:
a = 92
b = a numeral on the final drive case, to be di-
vided by 100 and added to “91”.
Example:
If the final drive case is marked “52”:
Therefore, the calculated final drive pinion
gear shim thickness is 0.28 mm. Shim sizes
are supplied in the following thicknesses.
a. 30–31 mm (1.18–1.22 in)

Final drive pinion gear shim thickness
A = a - b - 0.2
A = 92 - (91 + 52/100) - 0.2
= 92 - (91 + 0.52) - 0.2
= 92 - 91.52 - 0.2
=0.28
