REAR COVER REMOVAL

C~UTION:
Rear cover maybehard toremove because aring isused to
lock outer raceofrear bearing. Tofacilitate removalofrear
cover, heatjustbearing boxsection witha200W soldering iron.
Do not use aheat gun, asitcan damage diodeassembly.
REAR BEARING
CAUTION:
• Do not reuse rearbearing afterremoval. Replacewitha

new one.

• Donot lubricate rearbearing outerrace.
Rotor Check

1. Resistance test

Resistance: RefertoSOS (EL-61).

• Not within thespecified values...Replace rotor.
2. Insulator test
• Continuity exists...Replace rotor.
3. Check slipring forwear.

Slip ring minimum outerdiameter:
Refer toSOS (EL-61).

• Not within thespecified values...Replace rotor.
