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.
HOLD-IN TEST OF MAGNETIC SWITCH
1.
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.

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.)
Limit : 0.1 mm (.0039 in.)

IGNITION SYSTEM - Service Adjustment Procedures 8-111
SERVICE ADJUSTMENT PROCEDURES
CHECKING IGNITION TIMING NOEGIBA
IGNITION TIMING ADJUSTMENT
Adjustment conditions:
Coolant temperature: 80-90°C (170-I 90°F)
Lights and all accessories: Off
Transmission: N (Neutral)
1. Connect tachometer and timing light.
2. Start eng.ine and run at curb idle speed.
I
Curb idle speed rpm
First 500 km
(300 mile)
After 500 km
(300 mile)
725';;;
800 ?I00 3. To make adjustment at high altitude, disconnect pressure
sensor connector before stopping engine. Then restart
engine and run it at curb idle speed.
4. Check basic ignition timing and adjust if necessary.
Basic ignition timing: 7” + 2”BTDC 5. To adjust ignition timing, loosen distributor mounting nut
and turn distributor housing.
6. After adjustment, securely tighten mounting nut.
7. Reconnect pressure sensor connector disconnected in
Step 3. Then run engine at curb idle speed to make sure
that actual ignition timing is obtained.
. .
CHECKING IGNITION SYSTEM NOBDIDB
CHECKING CENTRIFUGAL ADVANCE EQUIPMENT 1.
Set the tachometer and timing light.
2. Start the engine and allow it to idle.
3. Pull out vacuum hose from vacuum controller.
4. Check the advance while slowly raising RPM. If the advance is
smooth when accompanying the increasing RPM, this is
normal.
Symptom Assumed causes
Excessive advance
Weakness of the governor spring
Sudden advance rise
Broken spring
Insufficient advance or large
Impaired movement of the gover-
hysteresis
nor weight or cam.
5. If the malfunction indicators above are confirmed, dismantle
and check the distributor.
6. After checking, let the engine idle and then turn the ignition
switch to OFF.
7. Remove the tachometer and timing light.‘.
