OIL PUMP PRESSURE TESTNl9FlAF
CHECKING THE OIL PUMP RELIEF PRESSURE1. 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 timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. Start the engine and idle it at 1,000
f 100 rpm.
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: 7.5-8.2
MPa (1,067-1,166 psi)
Caution
Pressure gauge shut off valve must not remain closed formore than 10 seconds.
5.If it is not within the standard value, overhaul the oil pump.
6.Remove the special tools, and then tighten the pressure hoseto the specified torque.
7. Bleed the system.
CHECKING THE PRESSURE UNDER NO-LOAD CONDITIONS1. Disconnect the pressure hose from the oil pump, and then
connect the special tool.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. Start the engine and idle it at 1,000
-t 100 rpm.
4.
Check whether or not the hydraulic pressure is the standard
value when no-load conditions are created by fully openingthe shut-off valve of the pressure gauge.
Standard value:
0.8-I .O MPa (114-142 psi)
Limit: 1.5
MPa (213 psi)
5. 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.
6.Remove the special tools, and then tighten the pressure hoseto the specified torque.
7. Bleed the system.

CHECKING THE STEERING GEAR PETENTION HYDRAULIC
PRESSURE1. Disconnect the pressure hose from the oil
pbmd, and iheh
connect the special tools.
2.Bleed the air, and then turn the steering wheel several timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50~60OC (122~14pyF).
3. ‘Start the engine and idle it at 1,000 +
100 rem: .‘,’.
4.Fully close and fully open the shut-off valve of the pressure
gauge.
5.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: 7.5-8.2 MPa (1,067-1,166 psi)6. When not within the standard value, overhaul the steering
gear box.
Remeasure fluid pressure.
7.Remove the special tools, and then tighten the pressure hoseto the specified torque.
8. Bleed the system.
OIL PRESSURE SWITCH CHECKNlSFUAB1. 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 timeswhile the vehicle is not moving so that the temperature of
the fluid rises to approximately
50-60°C (122-14OOF).3. The engine should be idling.
4. Disconnect the connector for the oil pressure switch, and
place an ohmmeter ,in position.
5.Gradually close the shut-off valve of the pressure gauge andincrease the hydraulic pressure then check whether the
hydraulic pressure that activates the switch is the standard
value.
Standard value: 1.5-2.0 MPa (213-284 psi)
6. Gradually open the shut-off valve and reduce the hydraulic
pressure; then check whether the hydraulic pressure that
deactivates the switch is the standard value.
Standard value: 0.7-1.2 MPa (100-171 psi)
7.Remove the special tools, and then tighten the pressure hoseto the specified torque.
8. Bleed the system.
