Starter
Motor
The starter motor
is
installed
on the
flywheel housing.
When
the
starting
button
is
pushed,
the
starter motor
pinion flies
out
and engages
the
ring gear
of the
flywheel.
Then
the
main contact
is
closed,
current flows,
and the
engine is started.
After the engine starts,
the
pinion automatically returns
to
its initial position when
the
starting
button
is
released.
Once
the
engine starts,
the
starting
button
should
be
released
immediately. Otherwise, the starter motor may
be
damaged or burned out.

Features
(1) The starter motor
is
compact and produces high outp
through high speed revolutions.
It
has increased
torqi
with
employing
a
reduction gear
to
reduce
the
spe<
between the armature and the pinion.
(2) The use
of
ball bearings
at
the armature shaft
(front
ai
rear sides) and
the
needle bearings
for the
gear
shi
(rear side) has boosted
the
durability
of
the starter
