Assembly
Position the forward gear bearing housing assem-
bly on a flat, level surface. (Mirror or glass can be
used.) Use depth gauge to measure distance from
flange of housing to flat surface as shown.
Add the appropriate shims to create a dimension
of 0.140 in. (3.556 mm).
To determine thickness of shims; use the following
example:
1.389 in. reading on the gauge
+ 0.011 in. shims required
= 1.400 in. required dimension
Apply Needle Bearing grease to the thrust bear-
ing. Position bearing around shoulder on the pro-
peller shaft.
Apply Needle Bearing grease to the thrust washer.
Place washer in recess of bearing housing.
Coat bearing surfaces of propeller shaft with gear-
case lubricant. Slide the propeller housing onto
the propeller shaft.
IMPORTANT: Use caution when assembling the
propeller shaft in the bearing housing. Thrust bear-
ing must remain around shoulder on the propeller
shaft.
Apply gearcase lubricant to the threads of the for-
ward gear bearing housing.
