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: 85 N·m (8.7 kg·m/63 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 N·m
(0.88 kg·m/6.4 lb·ft).

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 N·m (8.0 kg·m/58 lb·ft)
