SHIMMING AND GEAR BACKLASH CHECKS
Checking the Propeller Shaft
Thrust Play
After adjusting all gear positions, measure the
propeller shaft thrust play.
IMPORTANT:
Maintain the forward gear thrust
washer at the standard thickness. Adjust only the
reverse gear thrust washer.
Install a gear adjusting gauge to the propeller
shaft.
Push the propeller shaft inward. Hold the shaft in
and set the dial gauge to zero.
Slowly pull the propeller shaft outward. Record the
maximum gauge reading.
The actual propeller shaft thrust play should be
0.008 to 0.016 in. (0.20 to 0.40 mm).
•
If the measurement is greater than the specifi-
cation, increase the thickness of the reverse
gear thrust washer.
•
If the measurement is less than the specifica-
tion, decrease the thickness of the reverse gear
thrust washer.
