Example ( 2 )
Incorrect bottom side toe contact:
Correction measures:
• Increase thickness of forward gear shim.
(• Slightly decrease pinion gear shim thickness.)
Do not set tooth contact in this position (bottom side
toe contact). Chipping of pinion gear may result.
CHECKING PROPELLER SHAFT THRUST PLAY
After adjusting all gear positions, measure the propeller shaft
thrust play. If not within the following specification, a shim ad-
justment is required.
Propeller shaft thrust play: 0.2 – 0.4 mm
Measurement step:
1. Assemble gear adjusting gauge to the propeller shaft.
09951-09530: Gear adjusting gauge
2. Push 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.
• If measurement is more than specification, increase
propeller shaft thrust shim thickness.
• If measurement is less than specification, reduce pro-
peller shaft thrust shim thickness.
