ASSEMBLY AND ADJUSTMENT
5. Slowly turn the drive-shaft in and out,
and read the dial-gauge when the shaft
stops in each direction.
6. If the measurement is in the range 0.20
to 0.50 mm, it will be unnecessary to
add or remove shims.
7. If the measurement is less than 0.20
mm:
(0.35 – measurement)/2 =
Thickness of shim(s) to be decreased
If the measurement is more than 0.50
mm:
(Measurement – 0.35)/2 =
Thickness of shim(s) to be increased.
Standard backlash
(forward gear):
0.20 ~ 0.50 mm (0.008 ~ 0.020 in)
Reverse gear
1. Install a dial-gauge set on to the gear-
case.
2. Install a backlash indicator-rod on the
