(2) Reassembling the Stator Ass'y [23]
To align each screw hole of the Stator Ass'y [23] and the
Housing Ass'y [65] accurately, insert the guide bar (J-132
stator press pins [special repair tool, code no. 970911]
are recommended) to press-fit the Stator Ass'y [23] to the
Housing Ass'y [65] as shown in Fig. 2. After press-fitting,
hook the Brush Terminal [22] on the Brush Holder [62].

Ass'y [23] between the Stator Ass'y [23] and the seat for
the Hex. Hd. Tapping Screw D5 x 65 [34] in the Housing
Ass'y [65]. Secure the Stator Ass'y [23] to the Housing
Ass'y [65] with the two Hex. Hd. Tapping Screws D5 x 65
[34].
(3) Reassembly of the Armature [25]
Prior to assembling the Armature [25], ensure that the
Rubber Ring [36] is properly inserted into the groove of
the bearing case within the Gear Cover [28]. At this time,
be very careful not to damage the Rubber Ring [36]. Be
sure to mount the Bearing Bushing [32] and the Rubber
Bushing [31] to the Armature [25] before reassembly.
Do not perform reassembly with the Bearing Bushing [32]
