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

A: REMOVAL
1) Disconnect the positive (+) terminal after discon-
necting the negative (–) terminal of battery.
2) Remove the flange nut from battery rod and re-
move battery holder.
3) Remove the battery.
B: INSTALLATION
Install in the reverse order of removal.
Tightening torque:
3.4 N·m (0.35 kgf-m, 2.5 ft-lb)
NOTE:
•Clean the battery cable terminals and apply
grease to retard the formation of corrosion.
•Connect the positive (+) terminal, and then con-
nect the negative (–) terminal of the battery.
•Initial diagnosis of electronic control throttle is
performed after battery installation. Because of
this, start the engine 10 seconds or more after the
ignition switch is turned ON.
C: INSPECTION
WARNING:
•Electrolyte has toxicity; be careful of han-
dling the fluid.
•Avoid contact with skin, eyes or clothing. Es-
pecially at contact with eyes, flush with water
for 15 minutes and get prompt medical atten-
tion.
•Batteries produce explosive gases. Keep
sparks, flame, cigarettes away.
•Ventilate when charging or using in enclosed
space.
•For safety, in case an explosion does occur,
wear eye protection or shield your eyes when
working near any battery. Never lean over a bat-
tery.
•Do not let battery fluid contact eyes, skin,
fabrics, or paint-work because battery fluid is
corrosive acid.
•To lessen the risk of sparks, remove rings,
metal watch-bands, and other metal jewelry.
Never allow metal tools to contact the positive
battery terminal and anything connected to it
while you are at the same time in contact with
any other metallic portion of the vehicle. This
may cause short circuit.
1. EXTERNAL PARTS
Check the battery case, top cover, vent plugs, and
terminal posts for dirt or cracks. If necessary, clean
with water and wipe with a dry cloth.
Apply a thin coat of grease on the terminal posts to
prevent corrosion.
2. ELECTROLYTE LEVEL
Check the electrolyte level in each cell. If the level
is below MIN level, bring the level to MAX level by
pouring distilled water into the battery cell. Do not
fill beyond MAX level.

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.

3. Engine Oil
A: REPLACEMENT
1) Open the engine oil filter cap for quick draining of
the engine oil.
2) Drain the engine oil by removing the engine oil
drain plug.
3) Tighten the engine oil drain plug after draining
the engine oil.
NOTE:
Use a new drain plug gasket.
Tightening torque:
44 N·m (4.5 kgf-m, 33 ft-lb)
4) Fill engine oil through the level gauge up to the
center between the upper level and the lower level.
Place the vehicle on a level surface when checking
oil level. Use engine oil of the proper quality and
viscosity, selected in accordance with the following.
Recommended oil:
Refer to “RM” section. CANTS, RECOMMENDED MATERIALS, Rec-
ommended Materials.>
Engine oil capacity
When replacing engine oil and oil filter
Upper level
Approx. 5.7 2 (6.0 US qt, 5.0 Imp qt)
Lower level:
Approx. 4.7 2 (5.0 US qt, 4.10 Imp qt)
When replacing engine oil only
Upper level:
Approx. 5.5 2 (5.8 US qt, 4.8 Imp qt)
Lower level:
Approx. 4.5 2 (4.8 US qt, 4.0 Imp qt)
The proper viscosity oil helps the engine maintain
its ideal temperature, and cranking speed in-
creased by reducing viscosity friction in hot condi-
tion.
CAUTION:
When replenishing oil, it does not matter if the
oil to be added is a different brand from that in
the engine; however, use oil having the API
standard and SAE viscosity No. designated by
SUBARU.
NOTE:
If the vehicle is used in areas with very high temper-
atures or for other heavy duty applications, the fol-
lowing viscosity oils must be used:API Standard:
SM SAE Viscosity No.: 30, 40, 10W-50, 20W-40,
20W-50
5) Close the engine oil filler cap.
6) Start the engine and warm it up for a time.

1) Park the vehicle on a level surface.
2) Remove the oil level gauge and wipe it clean.
3) Reinsert the level gauge all the way. Be sure that
the level gauge is correctly inserted and in the
proper orientation.
4) Remove it again and check the oil reading.
If the engine oil level is below the “L” line, add oil to
bring the level up to the “F” line. To prevent overfill-
ing the engine oil, do not add oil above the “F” line
when the engine is cold.
5) Check whether it is notably dirty, or there is cool-
ant or gasoline mixed in. Replace if it is notably
dirty. If there is coolant or gasoline mixed in, check
the engine.
6) After pouring in engine oil, run the engine for
several minutes, then stop it. Wait for several min-
utes until the oil has returned to the oil pan.
