[22] and remove the Sensor Cover [28] and the O-Ring (S-85) [27].
2) Mark the engagement point between the Sensor Gear [26] and the Sensor Gear [56] with a magic marker

3) Remove the seven Hex. Socket Hd. Bolts (W/Flange) M5 x 16 [29] and the Gear Cover Ass'y [22].
Then First Pinion (B) [55], Second Pinion [47] and Third Pinion [43] can be removed. The Final Gear [18]
can be removed by removing the Retaining Ring for D25 Shaft [19]. If it is hard to remove the Final Gear
[18], use a bearing puller for removal. The Cam Shaft [12] can be removed just by pulling upward (toward
Cam Cover [6]) if the Final Gear [18] has already been removed.
* Marking should be made for easy reassembly. Otherwise,
adjust the sensor gears so that the number of teeth between
the engagement point and the projection is the same each
other as shown in Fig. 13-c and then mount them.
