D: ASSEMBLY
S179008A02
To assemble, 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
60°C (122 to 140°F)] 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.

1. DIODE
CAUTION:
Never use a megatester (measuring use for
high voltage) or any other similar measure for
this test; otherwise, the diodes may be dam-
aged.
1) Checking positive diode
Check for continuity between the diode lead and
the positive side heat sink. The positive diode is in
good condition if resistance is 1 Ω or less exists

only in the direction from the diode lead to the heat
sink.
(A)
(B)
2) Checking negative diode
Check for continuity between the negative side
heat sink and diode lead. The negative diode is in
good condition if resistance is 1 Ω or less exists
only in the direction from the heat sink to the diode
lead.
