Fluid Pressure Inspection
1. Assemble the SSTs as shown in the figure.
2. Disconnect the pressure pipe from the oil pump,
and connect the SSTs.
Tightening torque
29.4— 44.1 N·m {3.0— 4.4 kgf·m, 22— 32
ft·lbf}
3. Bleed the air from the system. (See 06-14-3 AIR
BLEEDING.)
4. Open the gauge valve fully.
5. Start the engine and turn the steering wheel fully
left and right to raise the fluid temperature to 50—
60 °C {122— 140 °F}.
6. Close the gauge valve completely.
7. Increase the engine speed to 1,000— 1,500 rpm
and measure the fluid pressure generated by the
oil pump.
• If the pressure is not within the specification,
repair or replace the oil pump component.
Caution
• If the valve is left closed for more than 5,
the fluid temperature will rise excessively
and adversely affect the oil pump.
Oil pump fluid pressure
10.31— 10.80 MPa {105.2— 110.1 kgf/cm
1,496— 1,566 psi}
8. Open the gauge valve fully and increase the
engine speed to1,000— 1,500 rpm.
9. Turn the steering wheel fully to the left and right,
then measure the fluid pressure generated at the
gear housing.
• If the pressure is not within the specification,
repair or replace the steering gear
component.
Caution
• If the steering wheel is kept in the fully
turned position for more than 5 seconds,
the fluid temperature will rise excessively
and adversely affect the oil pump.
Gear housing fluid pressure
10.31— 10.80 MPa {105.2— 110.1 kgf/cm
