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 ou
through high speed revolutions. It has increased toi
with
employing a reduction gear to reduce the sp
between the armature and the pinion.
(2) The use of ball bearings at the armature shaft
(front
rear sides) and the needle bearings for the gear s
(rear side) has boosted the durability of the starter
