CHAS
SHAFT DRIVE
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.
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.
