CAUTION:
When holding the rotor with a vise, place alumi-
num plates or wooden pieces on the vise jaws
to prevent rotor from damage.
5) Remove the ball bearing as follows.
(1) Remove the bolt, and then remove the bear-
ing retainer.
(2) Firmly install an appropriate tool (such as a
fit socket wrench) to bearing inner race.
(3) Push the ball bearing off the front cover us-
ing a press.

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.

PERIODIC MAINTENANCE SERVICES
9. Cooling System
A: INSPECTION
1) To check the radiator for leakage, fill it with en-
gine coolant, and attach the radiator cap tester (A)
to the filler neck, and apply pressure. Check the fol-
lowing points:
157 kPa (1.6 kg/cm2, 23 psi)
NOTE:
•Hose joints and other connections for leakage
•Each portion of radiator for leakage
•Be particularly careful not to deform the filler
neck of radiator when installing and removing the
tester and after testing.
•When performing this check, be sure to keep the
engine stationary and fill radiator with coolant.
•Wipe off check points before applying pressure.
•Use care not to spill coolant when detaching
tester from radiator.
2) Check the radiator cap valve open pressure us-
ing radiator cap tester.
NOTE:
Rust or dirt on the cap may prevent valve from func-
tioning normally:be sure to clean the cap before
testing.
Raise the pressure until the needle of gauge stops
and see if the pressure can be retained for five to
six seconds. The radiator cap is normal if a pres-
sure above the service limit value has been main-
tained for this period.
Radiator cap valve open pressure
Standard:
93 — 123 kPa (0.95 — 1.25 kg/cm2, 14 — 18
psi)
Service limit:
83 kPa (0.85 kg/cm2, 12 psi)
3) Start the engine, and then check it does not
overheat or it is cooled excessively. If it overheats
or it is cooled excessively, check the cooling sys-
tem.

4) Check the radiator fan operates using Subaru
Select Monitor, when the coolant temperature ex-
ceeds 95°C (203°F). If it does not operate, check
the radiator fan system.

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).

7) Perform the transfer clutch pressure test.
NOTE:
•Do not perform the transfer clutch pressure test
for more than 5 seconds at a time. Doing so will
make the engine oil and ATF deteriorate and the
clutch and brake to be adversely affected.
•After performing the transfer clutch pressure test,
be sure to cool down the engine for at least one
minute with the select lever set in the “P” or “N”
range, and at an idle speed of 1,200 rpm or less.
•Adjust the throttle valve angle in order to obtain
the “T/F Solenoid Pressure” displayed on the Sub-
aru Select Monitor.
8) Remove the ST and install the test plug.
9) Install the heat shield cover.
