4) How to measure the outer diameter of each pis-
ton:
Measure the outer diameter of each piston at the
height as shown in the figure. (Thrust direction)
NOTE:
Measurement should be performed at a tempera-
ture of 20°C (68°F).
Piston grade point H:
37.3 mm (1.4865 in)
Piston outer diameter:
Standard
A: 89.205 — 89.215 mm (3.5120 — 3.5124
in)
B: 89.195 — 89.205 mm (3.5116 — 3.5120
in)
0.25 mm (0.0098 in) oversize
89.445 — 89.465 mm (3.5215 — 3.5222 in)
0.50 mm (0.0197 in) oversize
89.695 — 89.715 mm (3.5313 — 3.5321 in)
5) Calculate the clearance between cylinder and
piston.
NOTE:
Measurement should be performed at a tempera-
ture of 20°C (68°F).
20 Cylinder to piston clearance at 20°C (68°F):
Standard
–0.010 — 0.010 mm (–0.00039 — 0.00039 in)
6) Boring and honing:
(1) If the value of cylindricality, out-of-round-
ness, or cylinder-to-piston clearance measured
is out of standard or if there is any damage on
the cylinder wall, rebore it to use an oversize
piston.
CAUTION:
When any of the cylinders needs reboring, all
other cylinders must be bored at the same time,
and use oversize pistons. Do not perform bor-
ing on one cylinder only. Nor use an oversize
piston for one cylinder only.
(2) If the cylinder inner diameter exceeds
89.715 mm (3.5321 in) after boring and honing,
replace the crankcase.
NOTE:
Immediately after reboring, the cylinder diameter
may differ from its real diameter due to temperature
rise. Thus, pay attention to this when measuring
the cylinder diameter.
3. PISTON AND PISTON PIN
1) Check the pistons and piston pins for damage,
cracks and wear, and the piston ring grooves for
wear and damage. Replace if faulty.
2) Measure the piston-to-cylinder clearance at
each cylinder. AND PISTON, INSPECTION, Cylinder Block.>If
any of the clearances is not within standard, re-
place the piston or bore the cylinder to use an over-
size piston.
3) Make sure that the piston pin can be inserted
into the piston pin hole with a thumb at 20°C (68°F).
Replace if faulty.
Standard clearance between piston pin and
hole in piston:
Standard
0.004 — 0.008 mm (0.0002 — 0.0003 in)

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.
