DISASSEMBLY SERVICE POINTS

.

<<A>> FRONT BRACKET ASSEMBLY REMOVAL

CAUTION

Do not insert a screwdriver too deep. The stator coil will be
damaged.
Insert a flat-tipped screwdriver between the front bracket
assembly and the stator core, and pry it downward to separate
the stator and front bracket assembly.

.

<<B>> ALTERNATOR PULLEY REMOVAL

CAUTION

Make sure not to damage the rotor.
Set the pulley upward, clamp the rotor in a vise, and remove
the pulley.

.

<<C>> STATOR REMOVAL

CAUTION

• Check that the heat from the soldering iron is not trans-

mitted to the diode for a long time.

• Use care that no undue force is exerted to leads of

diodes.

1. Use a soldering iron (180 to 250 W) to unsolder the stator.

This work should complete within approximately four
seconds to prevent heat from transferring to the diode.

2. When removing the rectifier from the regulator assembly,

unsolder the points soldered on the rectifier.

ROTOR CHECK

1. Check the continuity between the slip rings of the field coil. If

the resistance value is not within the standard value, replace
the rotor.

Standard value: approximately 2
