6. Close the gauge valve fully
7. Increase the engine speed to 1,000-1,500 rpm and measure the fluid pressure generated at the oil pump.

If it is less than the specification, replace the oil pump as a single unit.

Caution:  Do not maintain the gauge valve fully closed for 5 s or more. It is possible that oil temperature can rise and this will negatively affect
the oil pump.

Oil pump fluid pressure (oil temperature 50 - 60°C (122 - 140°F)) 10.4 - 11.0 kPa (107 - 112 kgf/cm, 1509 - 1595 psi) 

8. Open the gauge valve fully and increase the engine speed to 1,000-1,500 rpm.
9. Turn the steering wheel fully to the left and right, then measure the fluid pressure generated at the gear housing.

Caution:  Do not maintain the steering wheel fully turned for 5 a or more. It is possible that oil temperature can rise and this will negatively affect
the oil pump.

Note:  If the fluid pressure is less than the specification, it is possible that the oil pump or gear housing is not operating correctly. Replace the oil
pump as a single unit.

Gear housing fluid pressure (oil temperature 50 - 60°C (122 - 140°F)) 9.0 - 11.0 kPa (92 - 112 kgf/cm2, 1306 - 1595 psi) 

10. After removing the SSTs, tighten the oil pump side joint of the pressure hose to the specified torque.

Tightening torque 29.4 - 44.1 Nm (3.00 - 4.49 kgf-m, 21.6 - 32.5 ft. lbs.) 

11. Bleed the air from the system.
