Spring 7: 90501-450A2
Handle holder 8: EU0-23814-30
Compression distance a:
3.0–5.0 mm (0.118–0.197 in)
TIP:
• After installing the handle holder, pull the
drive shaft up to confirm that there is no
free play.
• Do not compress the spring more than 5.0
mm (0.197 in). Otherwise, the drive shaft
will not turn easily, making it difficult to
obtain correct measurements.
10. Install the special service tool 9 at the
lowest possible position where the drive
shaft diameter is 22.4 mm (0.882 in).
11. Set up the special service tools 0, A,
and B.

12. Turn the drive shaft slowly clockwise and
counterclockwise and measure the back-
lash between where the drive shaft stops
in each direction.
TIP:
• The resistance force of the spring makes it
difficult to turn the drive shaft. Therefore, to
obtain correct measurements, consider the
spring resistance force when turning the
drive shaft.
• Do not turn the drive shaft using too much
force. Otherwise, the forward 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
reverse gear and does not affect the back-
lash measurement.
13. Turn the drive shaft 180° clockwise and
measure the backlash again.
