STARTER
The starting system employs a magnetic type reduction
starter in which the motor shaft is also used as a pinion
shaft. When the starter switch is turned on, the contacts
of the magnetic switch are closed, and the armature
rotates. At the same time, the plunger is activated, and
the pinion is pushed forward by the shift lever to mesh
with ring gear.Then, the ring gear runs to start the engine. When the
engine starts and the starter switch is turned off, the
plunger returns, the pinion is disengaged from the ring
gear, and the armature stops rotation. When the engine
speed is higher than the pinion, the pinion idles, so that
the armature is not driven.

REMOVAL
1 Battery ground cable
2 Remove the slave cylinder and bind with wire it to
the frame.
3 Disconnect the connector from terminals “B” and
“S”.
4. Remove mounting bolts
5. Remove starter assembly
INSTALLATION
1. Install starter assembly, tighten the fixing bolt and
nut to the specified torque.
Torque: 94 Nꞏm (9.6 kgꞏm/69 lb ft)
2. Reconnect the starter terminals.
CAUTION: When installing the starter motor wiring,
do not allow the S-circuit wiring to obstruct the B-
circuit terminal.
Install the wiring exactly as shown on the attached
illustration.
If S-circuit wiring obstructs the B-circuit terminal,
harness cover breakage and short circuiting may
occur.2-1. Install the wire harness from the battery to the
terminal “B” with tightening torque 8.6 Nꞏm
(0.88 kgꞏm/6.4 lbꞏft).
2-2. Cover the terminal “B” together with wire
harness.
2-3. Connect the wire harness from starter relay to
the terminal “S”.
3. Install the clutch slave cylinder, tighten the fixing
bolt and nut to the specified torque.
Torque: 78 Nꞏm (8.0 kgꞏm/58 lbꞏft)

Pinion
1) Check by hand to see if the pinion rotates smoothly
in the dirve direction, or if it is locked when it is
rotated reversely.
If not, replace the pinion.
Yoke assembly
1) Check the magnet inside the yoke.
Replace the yoke assembly if it is broken.
REASSEMBLY
To install, follow the removal steps in the reverse order,
noting the following points:
Grease application places
1) Gears in reduction gear
2) Shift lever operating portion
3) Sliding potion of pinion
4) Plunger sliding portion of magnetic switch
Pinion jump-out dimension
1) Connect the (+) cable of battery to terminal S and
the (–) cable to terminal M. Turn the switch on, and
measure pinion travel dimension “L” in thrust
direction from the jump-out position.
In measuring the dimension, pull the pinion out a little in
the arrow direction.
Dimension L: 0.3 – 1.5 mm (0.01 – 0.06 in)If the measured value is out of standard, adjust the of
shims.

Pull-out test
Connect the magnetic switch to the battery as shown.
The negative side to the “M” terminal and the magnetic
switch body (housing); the positive side to the “S”
terminal. If the pinion has been ejected, the pull-in coil
is satisfactory.

Hold-in test
1. Next disconnect the “M” terminal.
2. The pinion should remain in the ejected position.
Return test
When the switch body is disconnected, the pinion
should return quickly.

CHARGING SYSTEM
GENERAL DESCRIPTION
GENERATOR
CHARGING CIRCUIT
The charging system is the IC integral regulator
charging system and its main components are
connected as shown in Figure.
The regulator is a solid state type and it is mounted
along with the brush holder assembly inside the
generator installed on the rear end cover.The generator does not require particular maintenance
such as voltage adjustment. The rectifier connected to
the stator coil has nine diodes to transform A.C. voltage
into D.C. voltage. This D.C. voltage is connected to the
output terminal of generator.

DIAGNOSIS
GENERAL ON-VEHICLE INSPECTION
The operating condition of the charging system is
indicated by the charge warning lamp. The warning
lamp comes on when the starter swtich is turned to
“ON” position. The charging system operates normallyif the lamp goes off when the engine starts. If the
warning lamp shows abnormality or if undercharged or
overcharged battery condition is suspected, perform
diagnosis by checking the charging system as follows:

1. Check visually the belt and wiring connector.
2. With the engine in stop status, turn the starter
switch to “ON” position and observe the warning
lamp.
1) If lamp does not come on:
Disconnect wiring connector from generator,
and ground terminal “L” on connector side.
2) If lamp comes on:
Repair or replace the generator.
