SHIMMING
Example:
If M is “32.33 mm” “P” is “+2”, then
T3 = 32.33 – 31.5 – 2/100 = 0.81
4. Round off the hundredth digit and
select the appropriate shim(s). In the
example above, the calculated number
is 0.81. The following table Instructs
you to round off 1 to 2 at the hundredth
place. Thus, the shim thickness is 0.82
mm.
NOTE:
●
Use a minimum number of shims to get
as close to the calculated thickness as
possible.
●
Install the shims with the thicker one fac-
ing the propeller.
Forward gear shim
NOTE:
Find the forward gear shim thickness (T1)
by selecting shims until the specified mea-
surement (M) is obtained with the special
tool.
