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

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.

6. V-belt
A: INSPECTION
1) Replace the belts if cracks, fraying or wear are
found.
2) Make sure that the V-belt automatic belt tension
indicator (A) is within the range of its use limit (D).
B: REPLACEMENT
1) Remove the cover.
2) Fit the tool to the belt tensioner mounting bolt.
3) Turn the tool in the direction of the arrow, and
loosen the V-belt to remove it.
4) Install in the reverse order of removal.
