Oil Pump Pressure Test
OIL PUMP PRESSURE TEST1. Disconnect the pressure hose from the pump. Connect the special tool between the pump and the pressure hose as illustrated.
2. Bleed the air, and then start the engine and turn the steering wheel several times, measure the fluid temperature by Temperature gauge so that the fluid temperature can rise to approximately 50°C (122 °F).
3. Increase the engine speed to 1,000 rpm.
4. 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
Oil pump pressure
Relief pressure: 6.6 - 7.3 MPa (68 - 75 kg/cm2, 967 - 1066 psi)
CAUTION: Do not keep the shut-off valve on the pressure gauge closed for more than ten seconds.
5. Remove the special tools, and tighten the pressure hose against the oil pump using the specified torque.
Tightening torque 55 - 65 Nm (5.5 - 6.5 kgs-m, 40 - 47 lb-ft)
6. Bleed the air in the system.
