(4) Reassembly of the armature unit
(a) Mounting the Motor Spacer [28]
Mount the Motor Spacer [28] to the Armature and Pinion Set [29]. If it is too hard to mount, support the
Motor Spacer [28] and press down the rear end of the armature shaft of the Armature and Pinion Set [29]
with a hand press.
(b) Mounting the Magnet [30]
Mount the Magnet [30] to the Armature and Pinion Set [29] so that the notch of the Magnet [30] faces the
rear of the Armature and Pinion Set [29]. Hold each part securely as the Armature and Pinion Set [29]
may be attracted to the Magnet [30] by the strong magnetic force (see Fig. 10).
(Note) Be careful that the ball bearing and the washer at the rear of the Armature and Pinion Set [29] may
come off due to the magnetic force of the Magnet [30].
Pay attention to the mounting direction of the Ring Gear [14], Slide Ring Gear [21], Pinion (C) [22] and Pinion
(B) [24] (see Fig. 5).
Mount the Front Case [10] to the Rear Case [18] so that the concave portion of the Front Case [10] aligns
with the protrusion of the Rear Case [18] (see Fig. 12).
Fit the protrusion of Washer (B) [27] in the concave portion of the Rear Case [18] and turn it clockwise viewing
from the armature until it contacts the Rear Case [18] (see Fig. 9).
