REAR COVER
CAUTION:
Rear cover may be hard to remove because a ring is used to lock outer race of rear bearing. To facili-
tate removal of rear cover, heat just bearing box section with a 200W soldering iron.
Do not use a heat gun, as it can damage diode assembly.
REAR BEARING
CAUTION:
lDo not reuse rear bearing after removal. Replace with a new one.
lDo not lubricate rear bearing outer race.

InspectionEKS00MZH
ROTOR CHECK
1. Resistance test
lNot within the specified values... Replace rotor.
2. Insulator test
lContinuity exists... Replace rotor.
3. Check slip ring for wear.
lNot within the specified values... Replace rotor.
BRUSH CHECK
1. Check smooth movement of brush.
lNot smooth... Check brush holder and clean.
2. Check brush for wear.
lReplace brush if it is worn down to the limit line.
PULLEY CHECK (WITH CLUTCH TYPE)
1. Check for locking (Outer ring is turned counterclockwise when
viewed from the rear).
lIf it rotates in both directions... Replace pulley.
2. Check for dragging (Outer ring is turned clockwise when viewed
from the rear).
lIf it locks or unusual resistance is felt... Replace pulley.
STATOR CHECK
1. Continuity test
lNo continuity... Replace stator.Resistance : Refer to SDS.SC-37,
"Alternator"
Slip ring minimum
outer diameter: Refer to SDS.SC-37,

RING FITTING IN REAR BEARING
lFix ring into groove in rear bearing so that it is as close to the
adjacent area as possible.
CAUTION:
Do not reuse rear bearing after removal.
REAR COVER INSTALLATION
1. Fit brush assembly, diode assembly, regulator assembly and
stator.
2. Push brushes up with fingers and install them to rotor.
