D: ASSEMBLY
To assemble, reverse order of disassembly.
1) Pulling up brush
Before assembling, press the brush down into
brush holder, and then fix them in that position by
passing a [1 mm (0.04 in) dia. length 4 to 5 cm (1.6
to 2.0 in)] wire through the hole shown in the figure.
CAUTION:
Be sure to remove the wire after reassembly.
2) Install the ball bearing.
(1) Set the ball bearing on the front cover, and
then securely install an appropriate tool (such as
a fit socket wrench) to the bearing outer race.
(2) Press the ball bearing into the specified po-
sition using a press.
(3) Install the bearing retainer.
3) Press the bearing (rear side) into the rotor shaft
using a press to install.
4) Heat the bearing box in rear cover [50 to 60
°
C
(122 to 140
°
