2) Remove the four through bolts. Then insert the
tip of a flat-head screwdriver into the gap between
the stator core and front bracket. Pry then apart to
disassemble.

CAUTION:
When holding rotor with vise, insert aluminum
plates or wood pieces on the contact surfaces
of the vise to prevent rotor from damage.

5) Ball bearing
Check rear ball bearing. Replace it if it is noisy or
if rotor does not turn smoothly.
B6M0486
2. STATOR
1) Continuity test
Inspect stator coil for continuity between its termi-
nals. When there is no continuity between indi-
vidual terminals, cable is broken. Replace stator
coil.
G6M0078
2) Insulation test
Inspect stator coil for continuity between stator
core and each terminal. If there is continuity,
replace stator coil.
G6M0079
3. BRUSH
Measure brush length. If brush is worn, replace
brush holder assembly.
Brush length ():
Standard
20.5 mm (0.807 in)
Limit
1.5 mm (0.059 in)
B6M0487A
4. DIODE ASSEMBLY
CAUTION:
Never use a high tension insulation tester,
such as a meggar as it will damage diodes with
its high tension.
The diode consists of eight diodes, four each being
located on the positive and negative sides. The
diode is necessary to restrict current flow to one
direction.
Check all diodes, for continuity. If any diode is
faulty, replace diode assembly.

Tightening torque (Spark plug):
20.6
±2.9 N´m (2.10±0.30 kg-m, 15.19±2.14
ft-lb)
CAUTION:
The above torque should be only applied to
new spark plugs without oil on their threads.
In case their threads are lubricated, the torque
should be reduced by approximately 1/3 of the
specified torque in order to avoid over-stress-
ing.

D: INSTALLATION (2500 cc
OUTBACK MODEL)
1. #1 SPARK PLUG
1) After setting spark plug in spark plug socket,
connect the spark plug socket, extension and Uni-
versal Joint to each other.
2) Screw spark plug into cylinder head using the
connected tools above mentioned. At this point, it
is necessary to support the rear end of the tools
with fingertips.
B6M0573
3) When spark plug is screwed in two or three
turns, temporarily disconnect the tools connected
in the first step.
4) Confirm that spark plug is screwed into the cyl-
inder head properly by touching it with finger. If it
is difficult to reach it by hand, confirm its condition
by using mirror and suchlike.
5) Cover ABS pipes with rag to prevent damage.
6) Re-insert the tools disconnected in three steps
before into plug hole, and set them again over the
spark plug.7) Set extension and ratchet in turn onto the con-
nected tools in plug hole, and tighten spark plug to
the specified torque.
