ELECTRICAL SYSTEM
CONSTRUCTION
1. Starter
The starter can be roughly divided into the following
sections:
(a) A motor section which generates a drive
power.
(b) An overrunning clutch section which
transmits an armature torque, preventing
engine overrun after starting
(c) A switch section which is operated when
actuating the overrunning clutch through a
lever and which supplies load current to the motor. (1) Magnetic
Switch (8) Pole Piece
(2) Shift Lever (9) Yoke

(4) Rear Bracket (11) Gear
(5) Brush (12) Clutch

Section View of Starter
The starter used with this engine is a new type of small, light-weight
starter called a high-speed internal reduction starter. Its differences in
construction from conventional starters are as follows.
(a) In conventional starters, the pinion slides on the motor
shaft (armature shaft). In the new type of starter,
however, the pinion shaft is separate from the motor shaft; the pinion slides only on the
pinion shaft.
(b) A reduction gear is installed between the motor shaft and a pinion shaft.
(c) The pinion sliding part is not exposed outside the starter so that the pinion may slide
smoothly without becoming fouled with dust and grease.
(d) The motor shaft is supported at both ends on ball bearings. The lever mechanism, switch
and overrunning clutch inner circuit are identical to conventional ones.
(e) The starter wiring is as shown.
