(4) Disassembly of the gear cover (Fig. 11)
(a) Remove the two Hex. Socket Hd. Bolts (W/Flange) M4 x 10 [55] from the bottom of the Gear Cover Ass'y
[21] and remove the Sensor Cover [30] and the O-Ring [29].
(b) Mark the engagement point between the Sensor Gear [26] and the Sensor Gear [25] with a magic marker.
(c) Remove the Seal Lock Screw (W/SP. Washer) M4 x 12 [28] from the Sensor Gear [26] and remove the
Sensor Gear [26] from the Cam Shaft [12]. Note that the Sensor Gear [25] of the sensor holder is adhered
to the volume shaft and cannot be removed.
*3. The engagement of teeth between the Sensor Gear [25] and the Sensor Gear [26] is very important as it
exerts an influence upon the bending angle. Pay special attention when disassembling and reassembling.
Improper engagement will not only make the bending angle incorrect but also damage the volume shaft to
which the Sensor Gear [25] is mounted (because the turning angle of the volume shaft is limited to 300˚).
*4. Perform reassembly so that the mark on the Sensor Gear [25] is aligned to the mark of the Sensor Gear
[26]. If marking is omitted before disassembly, adjust the sensor gears so that the number of teeth
between the projection of the Sensor Gear [25] and the engagement point B is the same each other and
then mount them.

Mark the engagement
point before disassembly.
The number of teeth
between the point B
and the projection
should be the same.
Adjust the position of the
protrusions by turning the gear.
