FINAL DRIVE

Ring gear shims
Thickness (mm) 0.30, 0.40, 0.50
110 Nm (11.0 m kg)
CAUTION:
Ring gear bearing thickness “f”
13 mm
Example:
If the final drive housing is marked “51” the ring
gear bearing housing is marked “35”, the ring
gear is marked “-05”, and “f” is 13.00:
B = (45 + 51 / 100) + (3 + 35 / 100) - [35.40 - 5 /
100) + 13]
= (45 + 0.51) + (3 + 0.35) - [(35.40 - 0.05) + 13]
= 45.51 + 3.35 -[(35.40 - 0.05) + 13]
= 48.86 - [35.35 + 13]
= 48.86 - 48.35
= 0.51
Therefore, the calculated ring gear shim thick-
ness is 0.51 mm.
Shim sizes are supplied in the following thick-
nesses.
Since the ring gear shims are only available in
0.10-mm increments, round off the hundredths
digit.
Hundredths Rounded value
0, 1, 2, 3, 4 0
5, 6, 7, 8, 9 10
In the example above, the calculated ring 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 ring gear shim.
2. Install:
shims (as calculated)
final drive pinion gear
bearing retainer
(with the bearing retainer wrench)
The bearing retainer has left-hand threads.
To tighten the bearing retainer, turn it coun-
terclockwise.
