Oil Pump Pressure Test
- Disconnect the pressure hose from the pump. Connect the special tool between the pump and the pressure hose as illustrated.
- Bleed the air, and then start the engine and turn the steering wheel several times so that the fluid temperature can rise to approximately 50-60°C (122-132°F) operating temperature.
- Increase the engine speed to 1,000 +/- 100 rpm.
- Close the shut-off valve of the special tool and measure the fluid pressure to confirm that it is within the standard value range.
Standard value
Relief pressure :
5.9 MPa (60 kg.cm2 , 853 psi)
CAUTION: Do not keep the shut-off valve on the pressure gauge closed for more than ten seconds. - If the fluid pressure is not within the standard value range, overhaul the oil pump.
- Remove the special tools, and tighten the pressure hose to the specified torque.
Tightening torque
55~65 Nm (550~650 kg.cm, 40.6~47.9 lb.ft)
- Bleed the system.
