4. Check pinion to stopper clearance (pinion gap) with a feeler
gauge.
Standard value : 0.5-2.0 mm (.020-.079 in.)
5. If pinion gap is out of specification, adjust by adding or remov-
ing gaskets between magnetic switch and front bracket.
PULL-IN TEST OF MAGNETIC SWITCH
1. Disconnect field coil wire from M-terminal of magnetic switch.
2. Connect a 12V battery between S-terminal and M-terminal.
Caution
This test must be performed quickly (in less than 10 sec-
onds) to prevent coil from burning.
3. If pinion moves out, then pull-in coil is good. If it doesn’t,
replace magnetic switch.

2. Disconnect field coil wire from M-terminal of in;ignetic switch.
Connect a 12V battery between S-terminal and body.
Caution
This test must be performed quickly (in less than 10 sec-
onds) to prevent coil from burning.
3. If pinion remains out, everything is in order. If pinion moves in,
hold-in circuit is open. Replace magnetic switch.

Carbon-pile rheostat
6EL07’ FREE RUNNING TEST
1. Place starter motor in a vise equipped with soft jaws and
connect a fully-charged 12-volt battery to starter motor as fol-
lows :
2. Connect a test ammeter (loo-ampere scale) and carbon pile
rheostat in series with battery positive post and starter motor
terminal.
3. Connect a voltmeter (16volt scale) across starter motor.
4. Rotate carbon pile to full-resistance position.
5. Connect battery cable from battery negative post to starter
motor body.
6. Adjust rheostat until battery voltage shown on the voltme-
ter reads 1 IV.
7. Confirm that the maximum amperage is within the stand-
ard value and that the starter motor turns smoothly and
freely.
Standard value : Current
Speed Max. 90A
Min. 3,000 rpm
RETURN TEST OF MAGNETIC SWITCH
1. Disconnect field coil wire from “M” terminal of magnetic
switch.
2. Connect a 12V battery between M-terminal and body.
Caution
This test must be performed quickly (in less than 10 sec-
onds) to prevent coil from burning.
3. Pull pinion out and release. If pinion quickly returns to its orig-
inal position, everything is in order. If it doesn’t, replace mag-
netic switch.

SERVICE POINTS OF DISASSEMBLY
9. CAUTION OF ARMATURE/ll. BALL
When removing the armature, do not lose the ball which acts
as a bearing for the armature and tip.
17. DISASSEMBLY OF SNAP RING/18. STOP RING
(1) Push the stop ring towards the snap ring using the proper
socket.
(2) After removal of the snap ring with the snap ring pliers,
remove the stop ring and the over-running clutch.
CLEANING STARTER MOTOR PARTS
1, Do not immerse parts in cleaning solvent. Immersing the yoke
and field coil assembly and/or armature will damage insulation.
Wipe these parts with a cloth only.
2. Do not immerse drive unit in cleaning solvent. Overrunning
clutch is pre-lubricated at the factory and solvent will wash
lubrication from clutch.
3. The drive unit may be cleaned with a brush moistened with
cleaning solvent and wiped dry with a cloth.
INSPECTION
CHECKING COMMUTATOR
(1) Place the armature on a pair of V blocks and check run-out with
a dial gauge.
Standard value : 0.05 mm (-0020 in.)

REPLACEMENT OF BRUSHES AND SPRINGS
1. Brushes that are worn beyond limit line, or are oil-soaked,
should be replaced.
2. When replacing field coil brushes, crush worn brush with pli-
ers, taking care not to damage pigtail.
3. Sand pigtail end with sandpaper to ensure good soldering.
4. Insert pigtail into hole provided in new brush and solder it.
Make sure that pigtail and excess solder do not come out onto
brush surface.
5. When replacing ground brush, slide the brush from brush
holder by prying retaining spring back.
TESTING ARMATURE
TESTING ARMATURE FOR SHORT-CIRCUIT
1. Place armature in a growler.
2. Hold a thin steel blade parallel and just above while rotating
armature slowly in growler. A shorted armature will cause
blade to vibrate and be attracted to the core. Replace shorted
armature.
TESTING ARMATURE FOR GROUNDING
Check the insulation in the space between the segments of the
commutator and the armature and coil core. If there is no conduc-
tivity this is normal.
CHECKING CIRCUIT BREAK BETWEEN ARMATURE AND COIL
Check conductivity between each segment. If there is conductiv-
ity this is normal.

IGNITION SYSTEM -General Information 8-105
IGNITION SYSTEM
GENERAL INFORMATION
NOUGAAB
The ignition system consists of battery, distributor, (igniter-integrated) ignition coil, spark plug, high tension cable,
ignition switch and connecting wire.

The distributor is composed of signal generator (signal rotor and igniter internalized pickup), linear current control
unit (igniter) advance control unit (governor and vacuum controller) and distribution unit (rotor plus distributor cap).

Vacuum controller
lEL153
IGNITER OPERATION
(1) When the signal rotor revolves a projection inside the signal rotor alternately moves away from and faces
towards the core detector inside the igniter.
(2) When the projection is separated from the core, an oscillating electrical circuit begins to oscillate, and when it
faces, magnetic flux issuing from the core moves across the inside of the signal rotor, so when loss increases,
oscillation ceases.
(3) This oscillation introduces power to the oscillation detector circuit, and after output is amplified it drives the
power transistor. During oscillation (when the projection and core are apart) electricity flowing through the
ignition coil and when oscillation stops (when the projection and core are facing) the electric current is inter-
rupted.
(4) The electrical detection circuit, in preventing excessive electrical flow to the power transistor, protects the
transistor.
