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.
Relief Pressure75 - 82 kg/cm2

REFRIGERANT CHARGING
Installation of Manifold Gauge
1. Close both high/low pressure hand valve of gauge before
installation of gauge to the charging valve.
2. Connect the low pressure hose of the gauge to the low
pressure charging valve and the high pressure hose of the
gauge to high pressure charging valve. Tighten the hose
nuts by hand.
Discharging of Refrigerant
1. Connect the manifold gauge to the charging valve.
2. Place the free end of center hose in a shop towel.
3. Slowly open the high pressure hand valve and discharge
refrigerant.
Notice
If refrigerant is allowed to escape too fast, compressor oil
will be drawn out of the system.
