Rear Cover

NOTE:
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
only the bearing box section until the temperature increases to
approximately 30

°

C (86

°

F) with a soldering iron (200W capacity).

CAUTION:

Never use a heat gun, as if can damage diode assembly.

ASSEMBLY
