12-2. Reassembly

Reassembly can generally be carried out as the reverse of
the disassembly procedure, with some items to be noted as
follows.
(1) Reassembly of the cam shaft unit (Fig. 22)
Perform reassembly so that the chamfered portion of the
Cam Shaft [12] is aligned with the pins of the Cam [8] in
the same direction.
* Otherwise, the Sensor Gear [56] cannot be mounted in
the proper position and damage to the volume and the
gear will result. Be sure to check the mounting direction
after reassembly.
(2) Reassembly of bracket (A) unit (Fig. 23)
Mount Bracket (A) [68] to Spring (C) [71] so that the
folded portion of Spring (C) [71] securely fits in the notch
of the Cutter Guard [70] (Fig. 23). Apply grease
(TUFREX 251) to the hole of Roller (C) [62] adequately
(Fig. 24).
(3) Reassembly of bracket (A) and (B) unit (Fig. 24)
Mount the Bolt (A) [65] to Bracket (A) [68]. Apply grease
(TUFREX 251) to the shaded areas shown in Fig. 24
adequately. Mount the Feather Key [66] to Bracket (A)
[68] and press-fit it to Bracket (B) [73].
(4) Installation of bracket (A) and (B) unit to the inner cover
(Figs. 19 and 20)
Mount bracket (A) and (B) unit into the Inner Cover Ass'y
[13] and secure it with two Hex. Socket Hd. Bolts M5 x 16
[67] and the Flange Nut M12 [39]. Hook one end of the
Return Spring [38] in the groove of the Pin for Spring [72]
and the other end on the projection of the Inner Cover
Ass'y [13]. Secure it with the Thrust Washer [37] and the
Seal Lock Screw (W/SP. Washer) M4 x 12 [36].
* For easy reassembly, mount the Return Spring [38] first
before mounting the Cam Shaft [12]. Use a flat-blade
screwdriver for mounting the Return Spring [38].
