Yamaha F225F Service Manual page 465

Specified torque:
15 N·m (1.5 kgf·m, 11.1 ft·lb)
TIP:
• Do not turn the drive shaft using too much
force. Otherwise, the reverse gear will turn,
leading to incorrect measurements.
• When turning the drive shaft, hold it using a
little force. A knocking sound may be heard
when the drive shaft is turned, but this is
the sound of the pinion contacting the for-
ward gear and does not affect the backlash
measurement.
16. Repeat steps 7 and 8 to measure the
reverse gear backlash.
17. Check that the reverse gear backlash
average is within specification.
Reverse gear backlash:
0.19–0.84 mm (0.0075–0.0331 in)
TIP:
Adjust the shim thicknesses if the reverse
gear backlash is out of specification.
18. Remove the special service tools, and
then install the outer plate cartridge,
cover, and water pump assembly. See
"Installing the water pump" (8-31).
19. Install the cover i, and then tighten the
cover bolts o to the specified torque.
