SERVICE POINTS OF DISASSEMBLY
7. REMOVAL OF FRONT BRACKET/lG. REAR BRACKET
(1) Insert plain screwdriver between front bracket and stator
core and pry downward.
Caution
Do not insert screwdriver too deep, as there is danger
of damage to stator coil.
(2) Rear cover may be hard to remove because a ring is used
to lock outer race of rear bearing. To facilitate removal of
rear cover, heat just bearing box section with a 200-W
soledering iron.
Do not use a heat gun, as it can damage diode assembly.
1. REMOVAL OF PULLEY
Clamp the rotor in a vise with soft jaws.
11. REMOVAL OF REGULATOR AND BRUSH HOLDER
(1) Unsolder three stator leads soldered to main diodes on
rectifier.
(2) Unsolder two plates soldered to rectifier.
Caution
1. When soldering or unsoldering, use care to make
sure that heat of soldering iron is not transmitted
to diodes for a long period. Finish soldering or un-
soldeing in as short a time as possible.
2. Use care that no undue force is exerted to leads of
diodes.
INSPECTION
ROTOR
l Check rotor coil for continuity. Check to ensure that there is
continuity between slip rings.
If resistance is extremely small, it means that there is a short.
If there is no continuity or if there is short circuit, replace rotor
assembly.
Standard value : 3.1 f2

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

8-112 IGNITION SYSTEM - Service Adjustment Procedures
CHECKING NEGATIVE PRESSURE ADVANCE EQUIPMENT
1. Set the timing light.
2. Start the engine and allow it to idle.
3. Pull out the vacuum hose from vacuum controller and attach
vacuum pump to nipple.
4. Check the advance while slowly applying negative pressure to
the vacuum pump. If the advance is smooth when accompa-
nying the increase in negative pressure, this is normal.

5. If the malfunction indicators above are confirmed, dismantle
and check the distributor.
6. Allow the engine to idle and then turn the ignition switch to
OFF.
7. Remove the vacuum pump and attach the vacuum hose to the
vacuum controller nipple.
8. Remove the timing light.
SPARK PLUG CABLE TEST NWGIGB
Hold the spark plug cable about 6-8 mm (.24-.31 in.) away from
engine proper (grounding portion such as cylinder block) and crank
engine to verify that sparks are produced.
SPARK PLUG TIEST NOUGIHB
Connect the spark plug to the high tension cable, ground outer
electrode (main body), and crank engine. In the atmosphere, only
short sparks are produced because of small discharge gap. If the
spark plug is good, however, sparks will occur in discharge gap
(between electrodes). In a defective spark plug, no sparks will
occur because of leak of insulation puncture.
