c. THRUST CLEARANCE ADJUSTMENT
Adjust the thrust clearance after replacement of the forward
bevel gear shim.
1) Check that the bearing holder assembly is securely
tightened to the specified torque on the propeller shaft
holder (P. 14-65).
Check that the clutch shifter and the shift slider are not
installed (P. 14-57).
2) Fix the propeller shaft holder assembly on the fixing tool
securely using the bolt as shown (P. 14-59).
3) Set the dial indicator perpendicularly so that its tip contacts
the end of the propeller shaft.
4) Move the propeller shaft up and down and read the runout
of the dial indicator. It must be within the specified range.
Standard value
5) If the thrust clearance exceeds the specification, increase
the thrust shim thickness and recheck the thrust clearance.
If the thrust clearance is less than the specification, reduce
the thrust shim thickness and recheck the thrust clearance.
