NOTE:
F is the deviation of the lower case dimen-
sion from standard. The F mark
a
is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the F
mark is unreadable, assume that F is zero
and check the backlash when the unit is
assembled.
Example:
If M1 is 28.08 mm and F is (+5), then
T1 = 28.60 + (+5)/100 28.08 mm
= 28.60 + 0.05 28.08 mm
= 0.57 mm
3. Select the forward gear shim(s) (T1) as
follows.
Example:
If T1 is 0.57 mm, then the forward gear
shim is 0.55 mm.
If T1 is 0.60 mm, then the forward gear
shim is 0.58 mm.
Selecting the reverse gear shims
1. Install the ball bearing, thrust washer,
and reverse gear onto the propeller shaft
housing.
2. Measure the gear height (M2) from the
thrust washer on the propeller shaft
housing.
NOTE:
Select the shim thickness (T2) by using the
specified measurement(s) and the calcula-
tion formula.
Measure the reverse gear at three points to
find the height average.
Calculation formula:
Forward gear shim thickness (T1) =
28.60 + F/100 M1
