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>> GENERATOR 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.

ASSEMBLY SERVICE POINTS

.

>>A<< REGULATOR ASSEMBLY INSTALLATION

After installing the regulator assembly, insert a wire through the
hole provided on the rear bracket while pressing down on the
brush, and secure the brush.
NOTE: By inserting a wire, the brush will be secured in place,
and the installation of the rotor will be easier.

.

>>B<< ROTOR ASSEMBLY INSTALLATION

After installing the rotor, remove the wire used to secure the
brush.

.

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

− 5 Ω

2. Check the continuity between the slip ring and the core. If

there is continuity, replace the rotor.

.

STATOR CHECK

1. Check the continuity between the coil lead. If there is no

continuity, replace the stator.

2. Check the continuity between the coil and the core. If there

is continuity, replace the stator.

.

RECTIFIER CHECK

1. Check the continuity between the positive rectifier and the

stator coil lead connection terminal with a tester. If there is
continuity between the terminals, the diode is shorted, so
replace the rectifier.

2. Check the continuity between the negative rectifier and the

stator coil lead connection terminal with a tester. If there is
continuity between the terminals, the diode is grounded, so
replace the rectifier.

3. Check the continuity of the three diodes by connecting an

ohmmeter to both ends of each diode. If there is continuity
between the directions, or if there is no continuity, the diode
is damaged, so replace the rectifier.

.

BRUSH CHECK

1. Replace the brush if the brush protrusion length shown in

the illustration is below the minimum limit value.

Minimum limit: 2 mm (0.08 inch)

2. The brush can be removed by unsoldering the brush lead

wire.

3. When installing a new brush, push the brush in to the brush

holder, and solder the lead wire.
