Ring gear shim
Thickness (mm) 0.30, 0.40, 0.50
115Nm (11.5 m kg)
CAUTION:
f = the ring gear bearing thickness constant
Ring gear bearing thickness“ f ”
13.00 mm
Example:
If the final drive housing is marked “45.51” the
ring gear bearing housing is marked “3.35” the
ring gear is marked “-05”, and “f” is 13.00:
B = 45.51 + 3.35 – [(35.40 – 5 / 100) + 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-
ness.
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 final 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:
shim(s) (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.
