D: ASSEMBLY
Assemble in the reverse order of disassembly.
1) Pulling up brush
Before assembling, press the brush down into
brush holder, and then fix them in that position by
passing a [1 mm (0.08 in) dia. 40 to 50 mm (1.6 to
2.0 in) long] wire through the hole as shown in the
figure.
CAUTION:
Be sure to remove the wire after reassembly.
2) Install the ball bearing.
(1) Set the ball bearing on the front cover, and
then securely install an appropriate tool (such
as a fit socket wrench) to the bearing outer race.
(2) Press the ball bearing into the specified po-
sition using a press.
(3) Install the bearing retainer.
3) Press the bearing (rear side) into the rotor shaft
using a press to install.
4) Heat the bearing box in rear cover [50 to 60°C
(122 to 140°F)], and then press the rear bearing
into rear cover.
CAUTION:
Grease should not be applied to rear bearing.
Remove the oil completely if it is found on bear-
ing box.
5) After reassembly, turn the pulley by hand to
check that rotor turns smoothly.
E: INSPECTION
1. DIODE
CAUTION:
Never use a mega tester (designed for reading
high voltage) or any other similar instrument
for this test; otherwise, the diodes may be dam-
aged.
1) Checking positive diode
Check for continuity between the diode lead and
positive side heat sink. The positive diode is in
good condition if resistance is 1 Ω o r l e s s o n l y i n t h e
direction from the diode lead to heat sink.
2) Checking negative diode
Check for continuity between the negative side
heat sink and diode lead. The negative diode is in
good condition if resistance is 1 Ω o r l e s s o n l y i n t h e
direction from the heat sink to diode lead.

2. ROTOR
1) Slip ring surface
Inspect the slip rings for contamination or any
roughness on the sliding surface. Repair the slip
ring surface using a lathe or sand paper.
2) Slip ring outer diameter
Measure the slip ring outer diameter. If the slip ring
is worn, replace the rotor assembly.
Slip ring outer diameter:
Standard
22.7 mm (0.894 in)
Limit
22.1 mm (0.870 in)
3) Continuity test
Check the resistance between slip rings using cir-
cuit tester.
If the resistance is not within the standard, replace
the rotor assembly.
Specified resistance:
Approx. 1.6 — 1.9 Ω
4) Insulation test
Check the continuity between slip ring and rotor
core or shaft. If resistance is 1 Ω or less, the rotor
coil is grounded, so replace the rotor assembly.
5) Ball bearing (rear side)
Check the rear ball bearing. Replace it if the noise
is heard or the rotor does not turn smoothly.
3. STATOR
1) Continuity test
Inspect the stator coil for continuity between each
end of the lead wires. If resistance is 1 MΩ o r m o r e ,
the lead wire is broken, so replace the stator as-
sembly.
2) Insulation test
Inspect the stator coil for continuity between stator
core and each end of lead wire. If resistance is 1 Ω
or less, the stator coil is grounded, so replace the
stator assembly.

4. BRUSH
1) Measure the length of each brush. If wear ex-
ceeds the service limit, replace the brush. Each
brush has the service limit mark (A) on it.
Brush length:
Service limit (1)
5.0 mm (0.197 in)
Standard (2)
18.5 mm (0.728 in)
2) Checking brush spring for proper pressure
Using a spring pressure indicator, push the brush
into the brush holder until its tip protrudes 2 mm
(0.08 in). Then measure the pressure of brush
spring. If the pressure is less than 2.2 N (224 g, 7
91 oz), replace the brush spring with a new one.
The new spring must have a pressure of 4.8 to 6.0
N (489 to 612 g, 17.26 to 21.58 oz).
5. BEARING (FRONT SIDE)
Check the front ball bearing. If the resistance is felt
while rotating, or abnormal noise is heard, replace
the ball bearing

Battery
STARTING/CHARGING SYSTEMS
3. SPECIFIC GRAVITY OF ELECTROLYTE
1) Measure specific gravity of electrolyte using a
hydrometer and a thermometer.
Specific gravity varies with temperature of electro-
lyte so that it must be corrected at 20°C (68°F) us-
ing the following equation:
S20 = St + 0.0007 × (t – 20)
S20: Specific gravity corrected at electrolyte
temperature of 20°C (68°F)
St: Measured specific gravity
t: Measured temperature (°C)
Determine whether or not battery must be
charged, according to corrected specific
gravity.
Standard specific gravity: 1.220 — 1.290
[20°C (68°F)]
2) Measuring the specific gravity of the electrolyte
in the battery will disclose the state of charge of the
battery. The relation between specific gravity and
state of charge is as shown in the figure.
D: MEASUREMENT
WARNING:
Do not bring an open flame close to the battery
at this time.
CAUTION:
•Prior to charging, corroded terminals should
be cleaned with a brush and common caustic
soda solution.
•Be careful since battery electrolyte overflows
while charging the battery.
•Observe instructions when handling the bat-
tery charger.
•Before charging the battery on the vehicle,
disconnect the battery ground terminal to pre-
vent damage of generator diodes or other elec-
trical units.
1. JUDGMENT OF BATTERY IN CHARGED
CONDITION
1) Specific gravity of electrolyte should be held
within the specific range from 1.250 to 1.290 for
more than one hour.
2) Voltage per battery cell should be held at a spe-
cific value in a range from 2.5 to 2.8 V for more than
one hour.
2. CHECK CONDITION OF CHARGE WITH
HYDROMETER
3. NORMAL CHARGING
Charge the battery at the current value specified by
manufacturer or at approximately 1/10 of battery's
ampere-hour rating.
4. QUICK CHARGING
Quick charging is a method that the battery is
charged in a short period of time with a relatively
large current by using a quick charger.
Since a large current flow raises electrolyte temper-
ature, the battery is subject to damage if the large
current is used for prolonged time. For this reason,
the quick charging must be carried out within a cur-
rent range that will not increase the electrolyte tem-
perature above 40°C (104°F).
Also the quick charging is a temporary mean to
bring battery voltage up to some level, and battery
should be charged slowly with low current as a rule.
CAUTION:
•Observe the items in 3. NORMAL CHARGING.
•Never use more than 10 A when charging the
battery because it will shorten the battery life.
