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)

INSPECTION AND REPAIR
Repair or replace necessary parts if extreme wear or
damage is found during inspection.
Armature
1) Measure the outer diameter of commutator, and
replace with a new one if it is out of the limit.
Standard: 38.0 mm (1.50 in)
Limit: 36.5 mm (1.44 in)
2) Check for continuity between commutator and
segments. Replace commutator if there is no
continuity (i.e., disconnected).3) Check for continuity between commutator and
shaft. Also, check for continuity between
commutator and armature core, armature core and
shaft. Replace commutator if there is continuity
(i.e., internally grounded).
4) Measure runout of armature core and commutator
with a dial gage. Repair or replace, if it exceeds the
limit.
Armature
Standard: 0.05 mm (0.002 in) Max.
Limit: 0.1 mm (0.004 in)
Commutator
Standard: 0.05 mm (0.002 in) Max.
Limit: 0.1 mm (0.004 in)

5) Polish the commutator surface with sand paper
#500 to #600 if it is rough.
6) Measure the depth of insulator in commutator.
Repair, if it is below the limit.
Standard: 0.5 – 0.8 mm (0.02 – 0.03 in)
Limit: 0.2 mm (0.008 in)

Magnetic switch
1) Continuity of shunt coil
Check for continuity between terminals S and coil
case.
Replace, if there is not continuity (i.e., coil is
disconnected.)2) Continuity of series coil
Check for continuity between terminals S and M.
Replace, if there is no continuity (i.e., coil is
disconnected).
3) Continuity of contacts
With the plunger faced downward, push down the
magnetic switch. In this state, check for continuity
between terminals B and M. Replace, if there is no
