PRECAUTIONS BEFORE SERVICE
PROTECTIN” THE VEHICLE NOODAAC
If theIre is a likelihood of damaging painted or interior parts
during service operations, protect them with suitable covers
(such as seat covers. fender covers, etc.).
REMOVAL AND DISASSEMBLY
When checking a malfunction, find the cause of the problem.
If it is determined that removal and/or disassembly is neces-
sary, perform the work by following the procedures contained
in this, Workshop Manual.
If punch marks or mating marks are made to avoid error in
assembly and facilitate the assembly work, be sure to make
them in locations which will have no detrimental effect on
performance and/or appearances.
If an area having many parts, similar parts, and/or parts which
are’ symmetrical right and left is disassembled, be sure to
arrange the parts so that they do not become mixed during the
assembly process.
1. Arrange the parts removed in the proper order.
2. Determine which parts are to be reused and which are to
be replaced.
3. If bolts, nuts, etc., are to be replaced, be sure to use only
the exact size specified.,
SPECIAL TOOLS
If other tools are substituted for the special tools to do service
or repair work, there is the danger that vehicle parts might be
damaged, or the mechanic might be injured; therefore, be
sure to use the special tool whenever doing any work for
which the use of one is specified.
PARTS TO IBE REPLACED
If any of the following parts are removed, they must be
replaced with new parts.
1. Oil seals
2. Gaskets (except rocker cover gasket)
3. Packings
4. O-rings
5. Lock washers
6. Cotter pins
7. Self-locking nuts

A jumper wire is used to close an open circuit. Never use one
to connect a power supply directly to a load.
4. Voltmeter
A voltmeter is used to measure the circuit voltage. Normally,
the positive (red lead) probe is applied to the point of voltage
measurement and the negative (black lead) probe to the body
ground.
5. Ohmmeter
An ohmmeter is used to.check continuity or measure resis-
tance of a switch or coil. If the measuring range has been
changed, the zero point must be adjusted before measure-
ment.
CHECKING SWITCHES In a circuit diagram, a switch is represented by a symbol and in the
idle state.
1. Normal open or normal close switch
Switches are classified into those which make the circuit open
and those which make the circuit closed when off.

2. SWITCH CONNECTION
This figure illustrates a complex switch. The switch plates
indicated by solid lines move in the direction of the arrow
when
operated. The continuity between terminals at each po-
sition is as indicated in the table below.
NOTE
M denotes continuity between terminals.
CHECKING RELAYS
1. When current flows through the coil of a relay, its core is
magnetized to attract the iron piece, closing (ON) the contact
at the tip of the iron piece. When the coil current is turned off,
the iron piece is made to return to its original position by a
spring, opening the contact (OFF).
2. By using a relay, a heavy current can be turned on and off
by a switch of small capacity. For example, in the circuit
shown here, when the switch is turned on (closed), current
flows to the coil of the relay. Then, its contact is turned on
(closed) and the light comes on. The current flowing at this
time to the switch is the relay coil current only and is very
small.
3. The relays may be classified into the normal open type and the
normal close type by their contact construction.
NOTE
The deenergized state means that no kurrent is flowing
through the coil and the energized state means that current is
flowing through the coil.

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.)

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.

air.
5. Using the plug gap gauge, check whether the plug gap reading
is normal, and if not, adjust it.
Standard value : 1.0-1.1 mm (.039-.043 in.)
CHECKING SPARK PLUG CABLE
(1) Check that there are no cracks in the cap or in the insulating
coating.
(2) Ctieck the resistance value.
