CAUTION:
When holding the rotor with a vise, place alumi-
num plates or wooden pieces on the vise jaws
to prevent rotor from damage.

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.

A: REPLACEMENT
1) Remove the battery and battery carrier.
2) Remove the air cleaner case.
3) Detach the connector from ignition coil.
4) Remove the ignition coil.
5) Remove the spark plug with a spark plug socket.
6) Tighten the new spark plug lightly with hand, and
then secure with a spark plug socket to the speci-
fied torque.
Recommended spark plug:
NGK: ILFR6B
Tightening torque:
21 N·m (2.1 kgf-m, 15.2 ft-lb)
7) Tighten the ignition coil.
Tightening torque:
16 N·m (1.6 kgf-m, 11.7 ft-lb)
NOTE:
•Be sure to place the gasket between the cylinder
head and spark plug.
•If the torque wrench is not available, tighten the
spark plug until gasket contacts cylinder head; then
tighten further 1/4 to 1/2 turns.

10.Engine Coolant
A: REPLACEMENT
1. REPLACEMENT OF ENGINE COOLANT
WARNING:
The radiator is of the pressurized type. Do not
attempt to open the radiator cap immediately
after the engine has been stopped.
1) Lift-up the vehicle.
2) Remove the under cover.
3) Place a container under drain pipe.
4) Remove the drain cock to drain engine coolant
into container.
5) For quick draining, open the radiator cap.
NOTE:
Be careful not to spill coolant on the floor.
6) Drain the coolant from reservoir tank.
7) Tighten the radiator drain cock securely after
draining coolant.
8) Pour cooling system conditioner through the fill-
er neck.
Cooling system protective agent:
Cooling system conditioner (Part number:
SOA345001)
9) Fill engine coolant into the reservoir tank up to
“FULL” level.
Recommended engine coolant:
Refer to “RM” section. ANT, RECOMMENDED MATERIALS, Recom-
mended Materials.>
Coolant capacity (fill up to “FULL” level):
Approx. 7.4 2 (7.8 US qt, 6.5 Imp qt)
NOTE:
The SUBARU Genuine Coolant containing anti-
freeze and anti-rust agents is especially made for
SUBARU engine, which has an aluminum crank-
case. Always use SUBARU Genuine Coolant,
since other coolant may cause corrosion.
10) Close the radiator cap, and start the engine.
Race 5 to 6 times at 3,000 rpm or less, then stop
the engine. (Complete this operation within 40 sec-
onds.)
11) Wait for one minute after the engine stops, then
open the radiator cap. If the engine coolant level
drops, add engine coolant into radiator up to the fill-
er neck position.
12) Perform the procedures 10) and 11) again.
13) Install the radiator cap and reservoir tank cap
properly.
14) Start the engine and operate the heater at max-
imum hot position and the blower speed setting to
“LO”.
15) Run the engine at 2,000 rpm or less until radia-
tor fan starts and stops.
NOTE:
•Be careful with the engine coolant temperature
gauge to prevent overheating.
•If the radiator hose becomes harden by engine
coolant pressure at this time, air purge seems to be
mostly completed.
16) Stop the engine and wait until the engine cool-
ant temperature lowers to 30°C (86°F).
17) Open the radiator cap. If the engine coolant lev-
el drops, add engine coolant into the coolant filler
tank up to the filler neck position and the reservoir
tank to “FULL” level.
18) Install the radiator cap and reservoir tank cap
properly.
19) Set the heater setting to maximum hot position
and the blower speed setting to “LO” and start the
engine. Perform racing at less than 3,000 rpm. If
the flowing sound is heard from heater core, repeat
the procedures from step 10).

Brake Line
PERIODIC MAINTENANCE SERVICES
3) Check the pedal stroke.
While the engine is idling, depress the brake pedal
with a 500 N (51 kgf, 112 lb) load and measure the
distance between the brake pedal and steering
wheel. With the brake pedal released, measure the
distance between pedal and steering wheel again.
The difference between the two measured values
must be less than specified value. If the measured
value is more than specification, there is possibility
of entering air in hydraulic unit.
Brake pedal stroke A:
115 mm (4.5 in)/ 500 N (51 kgf, 112 kg) or less
4) Check to see if air is in the hydraulic brake line
by the feel of pedal operation. If air appears to exist
in the line, bleed it from the system.
5) Check for even operation of all brakes, using a
brake tester or by driving the vehicle for a short dis-
tance on a straight road.
3. BRAKE SERVO SYSTEM
1) With the engine off, depress the brake pedal
several times applying the same pedal force. Make
sure the travel distance should not change.
2) With the brake pedal depressed, start the en-
gine. Make sure the pedal should move slightly to-
ward the floor.
3) With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds.
Make sure the pedal height should not change.
4) A check valve is incorporated into the vacuum
hose part. Disconnect the vacuum hose to inspect
function of check valve.
Make sure air flows from the booster end to engine
end but does not flow in the opposite direction in
the check valve.
5) Check the vacuum hose for cracks or other dam-
age.
NOTE:
When installing the vacuum hose on the engine
and brake booster, do not use soapy water or lubri-
cating oil on their connections.
6) Check the vacuum hose to make sure it is tightly
secured.
