INSPECTION
Steering Wheel Freeplay Inspection Procedure
1. Start the engine and set the wheels in straight ahead position.
2. Slightly move the steering wheel to the left and right and
measure steering wheel free play when the front wheel is
start to move.
Notice
If exceeds specification, the steering column shaft
connections and steering linkage .clearance. Replace or
repair if necessary.
Steering Angle Inspection Procedure
1. Place the front wheel on a measuring tool.
2. Rotate steering wheel all the way right and left and measure
steering angle
Notice
If out of standard, check or adjust toe-in.

Steering Effort Inspection Procedure
1 Place a vehicle on the paved flat ground with front wheels
in a straight ahead position.
2 Start the engine and run it at 1,000rpm.
3 Using a scale, measure the steering effort in both directions.

OIL PUMP PRESSURE CHECK
Oil Pump Pressure Check
1. Disconnect the pressure hose from the oil pump connect a
pressure gauge between the oil pump and pressure hose
2. Bleed the system . Start the engine and turn the steering
wheel form lock several times until oil temperature is up to
50°C
3. Run the engine at 1,000 rpm.
4. Close the pressure gauge valve and check oil pressure.
Notice
Do not keep the valve closed for more than 10 seconds.
5. Remove the pressure gauge and connect the pressure
hose.
6. Do bleeding procedure.
BLEEDING OF POWER STEERING
SYSTEM
Bleeding of Power Steering System
1. Disconnect the fuel line. Using a starter motor, crank the
engine and turn the steering wheel from lock to lock 5 or 6
times.
Notice
Do bleeding with engine cranking. If bleed with idling, there
can be a air contact with oil.
2. Connect the fuel feed line and start the engine at idle speed.
3. Turn the steering wheel from lock to lock until there is no
more air in oil reservoir.
4. Connect the oil level is within specification.
5. By turning the steering wheel left to right, check the oil level
change.
Notice
lIf oil is not changes more than 5mm, do bleeding again.
lIf oil level rises suddenly when stopped engine, again.

Charging Refrigerant
1. Connect the manifold gauge to the charging valve and
evacuate the system.
2. Connect the center hose of the gauge to the refrigerant
tank.
3. Open the high pressure valve and charge the system with
350g of refrigerant.
4. Close the high pressure valve and start the engine and run
the compressor.
Notice
Never open the high pressure valve when the compressor
is running. Refrigerant gas will be charged reverse.
5. Slowly open the low pressure valve and charge the system
with refrigerant.
Standard650 - 750 g
6. Close the low pressure valve after charging.
Notice
Checking the pressure through the sight glass is impossible
by applying & R-134a.
7. Stop the engine and disconnect the manifold gauge from
the system.
Operation Check
1. Place a dry bulb thermometer to the front duct.
2. Place a psychrometer close to the inlet of the cooling unit
(under the glove box).
3. Run the engine at 1,500 rpm.
4. Set the blower switch at ‘HI’ and A/C switch ‘ON”.
5. Set the temperature control lever at ‘COOL’.
6. Set the air flow control at ‘REC’.
7. Check that air conditioning system is stabilized.
