DISASSEMBLY
1. Remove the through bolt.
Insert the tip of a pry bar into the gaps between the
front cover and the stator core.
Pry apart and separate the front cover, rotor, the
rear cover and stator.
NOTE: Take care not to scratch or otherwise damage
the stator coil with pry bar.
2. Clamp the rotor in a vise and then remove the nut
and pulley.
3. Remove the rotor assembly from front cover.4. Remove screws with bearing retainer from front
cover and remove bearing.
5. Remove the mounting nuts holding the “B ”
terminal, the diode, and the brush holder.
6. Separate the rear cover from the stator.

4. Check for continuity between slip ring and rotor
core.
In case of continuity, replace the rotor assembly.
Stator Coil
1. Check for continuity across the stator coils. If no
continuity exists, replace the coils.
Resistance value at 20°C
Standard: Approx 0.07
2. Check for continuity across one of the stator coils
and stator core. If a continuity exists, replace the
coil.
Standard: More than 1M
Brush
Measure the brush length.
If more than limit, replace the brush.
Standard: 18.0 mm (0.709 in)
Limit: 5.5 mm (0.217 in)

Rectifier Assembly
1. Measure the resistance between each diode
terminal and aluminum diode fin in forward and
reverse directions with the connection of the tester
leads switched. The diodes are normal if resistance
is nearly zero ohms in one direction and is infinitely
high in the other direction.
2. If a diode has no resistance or equal resistance in
both directions, it is defective and should be
replaced together with the holder.
IC Regulator Assembly
Connect a variable resistor, two 12V batteries, a fixed
resistor, and a voltmeter to the IC regulator as shown in
illustration.
a. Measuring equipment specifications
1. Fixed resistor (R1) : 10 Ohms / 3W
2. Variable resistor (Rv) : 0 – 300 Ohms / 12W
3. Batteries (BAT1, BAT2) : 12V (2 Batteries)
4. DC voltmeter : 0 – 50V / 0.5 steps (4 Check points)
b. Measuring procedure
1. Measure the voltage “V1” across the first battery
(BAT1). If the reading is between 10 and 13 volts,
the battery is normal.
2. Measure the voltage “V3” across both the batteries
(BAT1, BAT2). If the reading is between 20 and 26
bolts, the batteries are normal.
3. Gradually increase the resistance of the variable
resistor from zero. Measure the voltage “V2” (the
voltage across the F and E terminals).
Check to see that the voltage across “V1” changes
at this time. If there is no change, the voltage
regulator is faulty and must be replaced.
4. Measure the voltage at “V4” (the voltage across the
variable resistor center tap and terminal E with the
variable resistor resistance held constant). The
measure voltage should be within the specified
(14.4 ± 0.3 volts) limits. If it is not, the regulator
must be replaced.
Reassembly
To reassemble, follow the disassembly steps in the
reverse order, noting the following points:
NOTE:
1) Never make battery connections with polarities
reversed, or battery will be shorted via the diodes.
This will cause damage to the diodes.
2) Do not connect generator B terminal to ground; it is
connected directly to the battery.
This cable will burn if it is connected to ground.
3) Make sure to disconnect the positive (+) terminal of
the battery when quick-charging battery.
Diodes may be damaged due to abnormal pulse
voltage generated by the quick charger.
4) When reassembling the front section to rear
section, insert a stiff wire into hole in the rear face
of the rear cover from the outboard side to support
the brush in raised position, then insert the front
section to which rotor is assembled.
5) Reassemble parts carefully to be sure they fit into
their original position, paying attention to the
insulated portions.
6) Wipe insulating tubes, washers and plates clean
and install them in position carefully to avoid getting
oil or grease on them.
