CHECKING PROPELLER SHAFT THRUST
PLAY
After adjusting all gear positions, measure the propeller shaft
thrust play. If not within the following specification, a shim
adjustment is required.
Propeller shaft thrust play: 0.2 – 0.4 mm (0.01 – 0.02 in)
NOTE:
Maintain the forward gear thrust washer at the standard thick-
ness (1.5 mm) and adjust only the reverse gear thrust washer
with shim.
1. Assemble gear adjusting gauge to the propeller shaft.
09951-09530: Gear adjusting gauge
2. Slowly push the propeller shaft inward.
3. Hold shaft in and set dial gauge pointer to zero.
4. Slowly pull shaft outward and read the maximum thrust play
on the dial gauge.
If measurement is more than specification, increase reverse
gear thrust washer thickness.
If measurement is less than specification, reduce reverse gear
thrust washer thickness.
