Disassembly
REAR COVER
CAUTION:
Rear cover may be hard to remove because a ring is used to
lock outer race of rear bearing. To facilitate 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:
IDo not reuse rear bearing after removal. Replace with a
new one.
IDo not lubricate rear bearing outer race.
Inspection
ROTOR CHECK
1. Resistance test
Resistance: Refer to SDS (SC-30).
INot within the specified values ... Replace rotor.
2. Insulator test
IContinuity exists ... Replace rotor.
3. Check slip ring for wear.
Slip ring minimum outer diameter:
Refer to SDS (SC-30).
INot within the specified values ... Replace rotor.
BRUSH CHECK
1. Check smooth movement of brush.
INot smooth ... Check brush holder and clean.
2. Check brush for wear.
IReplace brush if it is worn down to the limit line.

STATOR CHECK
1. Continuity test
INo continuity ... Replace stator.
2. Ground test
IContinuity exists ... Replace stator.
Assembly
RING FITTING IN REAR BEARING
IFix 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.
Take care not to damage slip ring sliding surface.
