DisassemblyNJSC0021REAR COVERNJSC0021S01CAUTION:
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 BEARINGNJSC0021S02CAUTION:
+Do not reuse rear bearing after removal. Replace with a
new one.
+Do not lubricate rear bearing outer race.
