TIP:
Do not turn the drive shaft with excessive
force. Otherwise, the forward gear will rotate,
leading to incorrect measurements.
13. Turn the drive shaft 180° clockwise and
measure the backlash again.
TIP:
• Measure the backlash at 4 points:
b
,
c
,
d
, and
e
, turning the drive shaft 180°
clockwise after each measurement. Write
down the measurement data.
• When turning the drive shaft, hold it with a
little force. A knocking sound may be heard
when the drive shaft is rotated, but this is
the sound of the pinion contacting the
reverse gear and does not affect the back-
lash measurement.
14. Determine the backlash average, and
then round down the average to the
1/100 place.
Example:
15. Check that the forward gear backlash
average is within specification.
TIP:
Adjust the shim thicknesses if the forward
gear backlash is out of specification.
16. Remove the special service tools.
17. Apply a load to the reverse gear by
installing the propeller
A
(without the
spacer
B
), collar
C
, and washer
D
.
18. Tighten the propeller nut
E
to the speci-
fied torque.
