DISASSEMBLY SERVICE POINTS
<>FRONT BRACKET ASSEMBLY
REMOVAL
CAUTION
Do not insert the screwdriver blades too deep.
Doing so could damage the stator coil.
Insert the blades of screwdrivers between the front
bracket assembly and stator core, and pry and
separate them with the screwdrivers.
<>ALTERNATOR PULLEY REMOVAL
CAUTION
Perform operation carefully not to damage the
rotor.
Clamp the rotor in a vise with the pulley facing up to
remove the pulley.
<>STATOR / REGULATOR ASSEMBLY
REMOVAL
CAUTION
•Use a 180 − 250 W soldering iron, and finish
unsoldering within four seconds. Diodes will
be damaged by heat if unsoldering time is too
long.
•Avoid applying undue force to the diode
leads.
1. Unsolder the stator leads from the main diode of
the rectifier assembly when the stator is removed.
2. When removing the rectifier assembly from the
regulator assembly, undo the soldered points on
the rectifier assembly.
REASSEMBLY SERVICE POINTS
>>A< INSTALLATION
After installing the regulator assembly, insert a piece
of wire through the hole in the rear bracket while
pressing the brush to keep the brush against
movement.
NOTE: Holding the brush with the wire facilities
