9-28 LOWER UNIT
CHECKING PROPELLER SHAFT THRUST PLAY
After adjusting all gear positions, measure propeller shaft thrust
play. If not within following specification, a shim adjustment is
required.
Propeller shaft thrust play : 0.2 – 0.4 mm
(0.01 – 0.02 in.)
NOTE:
Maintain forward gear thrust washer at standard thickness (3.0
mm) and adjust only reverse gear thrust washer with shim.
Measurement step :
1. Affix gear adjusting gauge to propeller shaft.
\ 09951-09530 : Gear adjusting gauge
2. Slowly push propeller shaft inward.
3. Hold shaft in and set dial gauge pointer to zero.
4. Slowly pull propeller shaft outward and read maximum thrust
play.
If measurement is more than specification, increase reverse
gear thrust washer thickness.
If measurement is less than specification, reduce reverse gear
thrust washer thickness.
