PINION GAP ADJUSTMENT
1. Disconnect the field coil wire from the M-terminal of the
magnetic switch.
2. Connect a 12-volt battery between the S-terminal and
M-terminal.
This test must be performed quickly (in less than 10 sec-
onds) to prevent the coil from burning.
3. Set the switch to "ON", and the pinion will move out.
4. Check the pinion-to-stopper clearance (pinion gap) with a
feeler gauge.
Standard value: 0.5
2.0 mm (0.02 0.07 inch)
5. If the pinion gap is out of specification, adjust by adding or
removing gasket(s) between the magnetic switch and front
bracket.
.
MAGNETIC SWITCH PULL-IN TEST
1. Disconnect the field coil wire from the M-terminal of the
magnetic switch.
This test must be performed quickly (in less than 10 sec-
onds) to prevent the coil from burning.
2. Connect a 12-volt battery between the S-terminal and
M-terminal.
3. If the pinion moves out, the pull-in coil is good. If it doesn't,
replace the magnetic switch.

<> SNAP RING AND STOP RING REMOVAL
1. Press a long socket wrench of appropriate size to the stop
ring. Then tap the socket wrench to remove the stop ring to
the pinion gear side.
2. After removing the snap ring (by using snap-ring pliers),
remove the stop ring and the overrunning clutch.
STARTER MOTOR PART CLEANING
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 shop towel only.
2. Do not immerse the drive unit in cleaning solvent.
Overrunning clutch is pre-lubricated at the factory and
solvent will wash lubrication from the clutch.
3. The drive unit may be cleaned with a brush moistened with
cleaning solvent and wiped dry with a shop towel.

PRIMARY COIL AND IGNITION POWER
TRANSISTOR CONTINUITY CHECK
NOTE: No test can be performed on the Primary side of coil.
.
SECONDARY COIL CHECK
NOTE: It is impossible to check the secondary coil through the
continuity check as a diode is integrated in the secondary coil
circuit of this ignition coil. Accordingly, check the secondary coil
in the following procedure.
1. Disconnect the ignition coil connector.
2. Remove the ignition coil and install a new spark plug to the
ignition coil.
3. Connect the ignition coil connector.
4. Disable vehicle fuel pump by removing fuel pump relay or
disconnecting fuel pump connector D-18 (under rear seat).
5. Ground the side electrode of the spark plug and crank the
engine.
6. Check that spark is produced between the electrodes of the
spark plug.
7. If no spark is produced, replace the ignition coil with a new
one and recheck.
8. If spark is produced with the new ignition coil, replace the
old one as it is faulty. If no spark is produced again, the
ignition circuit is suspected as faulty. Check the ignition
circuit.

INSTALLATION SERVICE POINT
.
>>A<< BRAKE DRAG FORCE CHECK
1. In order to measure the brake drag force, measure the hub
torque with the pads removed by the following procedure.
Use a spring scale to measure the hub torque in the forward
direction. Record hub torque with pads removed.
Do not let any oil, grease or other contamination get onto
the friction surfaces of the pads and brake discs.
2. After re-installing the caliper support to the knuckle, install
the pad clips and the pads to the caliper support.
3. Clean the piston and insert into cylinder with special tool
MB990520.
4. Be careful that the piston boot does not become caught,
when lowering the caliper assembly and installing the lock
pin bolt.
5. Check the brake drag force as follows.
(1) Start the engine and hold the brake pedal down for 5
seconds. [Pedal depression force: approximately 200 N
(45 pound)]
(2) Stop the engine.
(3) Turn the brake disc forward 10 times.

LUBRICATION AND MAINTENANCE
GENERAL00-34
LUBRICATION AND MAINTENANCEM1001001200336
Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum pro-
tection for the vehicle owner's investment against all
reasonable types of driving conditions. Since these
conditions vary with the individual vehicle owner's
driving habits, the area in which the vehicle is oper-
ated and the type of driving to which the vehicle is
subjected, it is necessary to prescribe lubrication and
maintenance service on a time frequency as well as
mileage interval basis.
Oils, lubricants and greases are classified and
graded according to standards recommended by the
Society of Automotive Engineers (SAE) and the Aus-
tralian Petroleum Institute (API).
MAINTENANCE SCHEDULES
For Information on service maintenance refer to the
"Service handbook".
ENGINE OIL
Tests have shown that laboratory animals
develop skin cancer after prolonged contact with
used engine oil. Accordingly, the potential exists
for humans to develop a number of skin disor-
ders, including cancer, from such exposure to
used engine oil. Therefore, when changing
engine oil, be careful not to touch it as much as
possible. Protective clothing and gloves, that
cannot be penetrated by oil, should be worn. The
skin should be thoroughly washed with soap and
water, or use waterless hand cleaner, to remove
any used engine oil. Do not use petrol, thinners,
or solvents.Either of the following engine oils should be used:
1. Engine oil conforming to the ACEA classification:
"For service A1, A2 or A3.
2. Engine oil conforming to the API classification:
"For service SG" or higher.
FUEL USAGE STATEMENT
Using leaded petrol in this car will damage the
catalytic converters and heated oxygen sensors,
and affect the warranty coverage validity.
This vehicle must use unleaded petrol only.
This vehicle has a fuel filler tube which is especially
designed to accept only the smaller-diameter
unleaded petrol dispensing nozzle.
The 3.8L model is designed to operate on unleaded
petrol having an octane rating (DIN 51607) of 90
RON or higher.
.
PETROL CONTAINING ALCOHOL
Some petrol sold at service stations contain alcohol
although they may not be so identified.
Using fuels containing alcohol is not recommended
unless the nature of the blend can be determined as
being satisfactory, as follows.
Gasohol: A mixture of 10% ethanol and 90%
unleaded gasoline may be used in your vehicle. If
driveability problems are experienced as a result of
using gasohol, it is recommended that the vehicle be
operated on petrol.
Methanol: Do not use petrol containing methanol
(wood alcohol). Using this type of alcohol can result
in vehicle performance deterioration and damage
critical parts in the fuel system components. Fuel
system damage and performance problems resulting
from the use of petrol containing methanol may not
be covered by the new vehicle warranty.
MATERIALS ADDED TO FUEL
Indiscriminate use of fuel system cleaning agents
should be avoided. Many materials intended for gum
and varnish removal may contain highly active sol-
vents or similar ingredients that can be harmful to
gasket and diaphragm materials used in fuel system
component parts.

MAINTENANCE SERVICE

The temperature of the surface of the belt should be as
close as possible to underhood temperature.
Do not let any contaminants such as water or oil get
onto the microphone.
If strong gusts of wind blow against the microphone or
if there are any loud sources of noise nearby, the val-
ues measured by the microphone may not correspond
to actual values.
If the microphone is touching the belt while the mea-
surement is being made, the values measured by the
microphone may not correspond to actual values.
Do not take the measurement while the vehicle's engine
is running.
5. Hold special tool MB991668 (microphone) to the middle of
the drive belt between the pulleys (at the place indicated by
the arrow), about 10
20 mm (0.4 0.8 inch) away from the
rear surface of the belt and so that it is perpendicular to the
belt (within an angle of
15 degree angle).
6. Gently tap the middle of the belt between the pulleys (the
place indicated by the arrow) with your finger as shown in
the illustration, and check that the vibration frequency of the
belt is within the standard value.
Standard value:
NOTE: Because the frequency depends on the belt material,
confirm Part No. shown on the reverse of the belt.
