Disassembly and Assembly

INFOID:0000000003860540

DISASSEMBLY

Rear bracket assembly

NOTE:
Rear bracket assembly may be hard to remove because a ring is
used to lock outer race of rear bearing. To facilitate removal of rear
bracket assembly, heat only the bearing box section until the temper-
ature 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.
