LOWR
SHIMMING
NOTE:
"F" is the deviation of the lower case
dimension from standard. It is stamped
on the trim tab mounting surface of the
lower case in 0.01 mm units.
If the "F" mark is missing or unreadable,
assume an "F" mark of "0" and check the
backlash when the unit is assembled.
Example:
If M is "23.90 mm" "F" is "–3", then
T1 = 24.50 + (–3/100) – 23.90 = 0.57
2. Round off the hundredth digit and
select the appropriate shim(s). In the
example above, the calculated number
is 0.57. The following table Instructs
you to round off 7 to 5 at the hundredth
place. Thus, the shim thickness is 0.55
mm.

Available shim thickness:
0.10, 0.12, 0.15, 0.18, 0.30, 0.40
and 0.50 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.
Reverse gear shim selection is unneces-
sary.
