SHAFT DRIVE

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:
Therefore, the calculated ring gear shim
thickness is 0.41 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 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.
