Position the gear assembly so the indicator nee-
dle makes contact with the flange on the housing.
The indicator needle must be parallel with the side
of the gear housing and perpendicular to the table
surface. Zero the dial indicator.
Grip the bearing housing 180° apart and pull up to
get a reading on the indicator. To determine thick-
ness of shims; use the following example:
0.030 in. of shims in the assembly
– 0.020 in. reading on the dial indicator
= 010 in. difference
+ 0.001 in. necessary end play
= 0.011 in. required shims
Remove the 0.030 in. (0.7 mm) of shims from the
assembly. Reassemble the gear assembly using a
combination of shims to achieve the required
thickness. Apply Nut Lock to the threads of the set
screws and torque to 144 to 168 in. lbs. (16.3 to
19 N·m).
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. Thrust bearing must remain
around shoulder on the propeller shaft.
Apply gearcase lubricant to the threads of the for-
ward gear bearing housing.
