D: ASSEMBLY
Assemble in the reverse order of disassembly.
1) Pulling up brush
Before assembling, press the brush down into the
brush holder with your finger and secure in that
position by passing a [2 mm (0.08 in) dia. length 4
to 5 cm (1.6 to 2.0 in)] wire (A) through the hole
shown in the figure.
CAUTION:
Be sure to remove the wire after reassembly.

2) Heat the bearing box in the rear bracket [50 to
60ÉC (122 to 140ÉF)] and press the rear bearing
into the rear bracket.
CAUTION:
Grease should not be applied for the rear bear-
ing. Remove oil completely if it is found on the
bearing box.
3) After reassembly, turn the pulley by hand to
check that the rotor turns smoothly.

4) When tester indicates 12 volts when its probe
reaches point ªAº, a broken circuit occurs between
point ªAº and the negative terminal. Slowly move
tester probe toward the negative terminal while
contacting it on heat wire to locate point where
tester indication changes abruptly (0 volts). This is
the point where a broken circuit occurs.
When tester indicates 0 volts when its probe
reaches point ªAº, a broken circuit occurs between
point ªAº and the positive terminal. Locate a point
where tester indication changes abruptly (12 volts)
while slowly moving tester probe toward the posi-
tive terminal.

B: REPAIR
1) Clean broken wire and the surrounding area.
2) Cut off slit on (used) thin film by 0.5 mm (0.020
in) width and 10 mm (0.39 in) length.
3) Place the slit on glass along the broken wire,
and deposit conductive silver composition
(DUPONT No. 4817) on the broken portion.

4) Dry out the deposited portion.
5) Inspect the repaired wire for continuity.
