f = the ring gear bearing thickness constant.
Ring gear bearing thickness
13.00 mm (0.51 in)
Example:
If the final gear case 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 - [35.45 + 13]
= 48.86 - 48.45
= 0.41
Therefore, the calculated ring gear shim
thickness is 0.41 mm.
Shim sizes are supplied in the following thick-
nesses.
Ring gear shims
Thickness (mm)
0.25 0.30 0.40 0.50
Since the ring gear shims are only available
in 0.10 mm increments, round off the hun-
dredths digit.

In the example above, the calculated ring
gear shim thickness is 0.41 mm. The chart in-
structs you to round off the 1 to 0. Thus, you
should use a 0.40 mm ring gear shim.
