OIL PUMP PRESSURE TEST
(POWER STEERING)
37200230127
1. Disconnect the pressure hose from the oil pump, and
then connect the special tools.
2. Bleed the air, and then turn the steering wheel several
times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50 – 60
_
C.
3. Start the engine and idle it at 1,000
±
100 r/min.
4. Fully close the shut-off valve of the pressure gauge and
measure the oil pump relief pressure to confirm that it
is within the standard value range.
Standard value: 8.3 – 9.0 MPa
Caution
Pressure gauge shut off valve must not remain closed
for more than 10 seconds.
5. If it is not within the standard value, replace the oil pump.
6. Check whether or not the hydraulic pressure is the
standard value when no-load conditions are created by
fully opening the shut-off valve of the pressure gauge.
Standard value: 0.8 – 1.0 Mpa
7. If it is not within the standard value, the probable cause
is a malfunction of the oil line or steering gear box, so
check these parts and repair as necessary.
8. Turn the steering wheel all the way to the left or right;
then check whether or not the retention hydraulic pressure
is the standard value.
Standard value: 8.3 – 9.0 MPa
9. When not within the standard value, overhaul the steering
gear box.
Remeasure fluid pressure.
10. Remove the special tools, and then tighten the pressure
hose to the specified torque.
Tightening torque: 18 Nm
11. Bleed the system.
