SHAFT DRIVE
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:
A = 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 thickness
is 0.51 mm.
Shim sizes are supplied in the following thickness.
Thickness (mm)
Since the ring gear shims are only available in
0.10 mm increments, round off the hundredths
digit.
Hundredths
0, 1, 2, 3, 4
5, 6, 7, 8, 9
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)
CAUTION:
The bearing retainer has left-hand threads. To
tighten the bearing retainer, turn it counter-
clockwise.
