INSTALLATION
Note
After installing the distributor, adjust the ig-
nition timing (Refer to 5—11).
1. Apply engine oil to the O-ring and driven gear.

Note
Gear driven type, check that the No.1 cylin-
der is at top dead center and aline the distrib-
utor matching marks.

2. Install the distributor and connect the high-tension
leads and distributor connector.
3. Tighten lock bolt to the specified torque.

1. Place a soldering iron (200W) on the bearing box
for 3 or 4 minutes to heat it to about 50—60°C
(122—140°F).
Pull out the three bolts, and then insert a screw-
driver between the stator and front bracket and
separate them.
Note
a) If the bearing box is not heated, the bear-
ing cannot be pulled out because the rear
bearing and rear bracket fit together very
tightly.
b) Be careful not to force the screwdriver in
too far. The stator may become scratched.
2. Separate the rear and front sections.
Note
Be careful not to lose the stopper spring that
fits around the circumference of the rear
bearing.

ASSEMBLY
Assemble in the reverse order of disassembly, refer-
ring to assembly note.
Assembly Note
Stopper spring installation
1. Fit the stopper spring into the eccentric groove of
the rear bearing circumference.
2. Check that the protruding part of the spring is fitted
into the deepest part of the groove.
Front bracket and rotor
When assembling the front bracket and rotor, tight-
en the locknut to the specified torque.
Tightening torque:
49—88 N-m (5—9 m-kg, 36—65 ft-lb)
Brush lifting
1. Before assembly, use a finger to hold the brushes
into the brush holder; then pass a wire
(2
mm,
40—50 mm, 00.08 in, 1.6—2.0 in) through the
hole shown in the figure.
2. Secure the brushes in position.
Note
Be sure to remove wire after assembly is com-
pleted.
Rear bearing installation
1. Heat the rear bracket.
2. Press the rear bearing into the rear bracket.
3. Check that the rotor turns easily.
