Shimming (counter rotation model)
13. Determine the backlash average, and
then round down the average to 2
decimal places.
Example:
14. Check that the forward gear backlash
average is within specification.
TIP:
Adjust the shim thicknesses if the forward
gear backlash is out of specification.
15. Remove the special service tools from
the propeller shaft.
16. Remove the shift rod and propeller shaft
housing assembly.
17. Install the washers “1” between the
reverse gear “2” and the propeller shaft
“3”.
18. Install the original forward gear shims
(T2) and propeller shaft housing
assembly, and then tighten the ring nut to
the specified torque.
19. Repeat steps 11–13 to measure the
reverse gear backlash.
20. Check that the reverse gear backlash
average is within specification.
TIP:
Adjust the shim thicknesses if the reverse
gear backlash is out of specification.
21. Remove the special service tools and
washers, and then install the propeller
shaft housing assembly, shift rod, and
water pump assembly.
