Order of execution
1. Disconnect the pressure hose from the power steering pump. Connect a special measuring tool between the disconnected pressure hose and the pump, as shown in the figure.
2. Bleed the hydraulic power steering, then start the engine and turn the steering wheel several times until the fluid temperature rises to 50°C.
3. Increase engine speed to 1000min-1.
4. Close the special tool switch valve and measure the pressure.
Power steering pump fluid pressure: 6.2 MPa
Warning! Do not keep the special tool switch valve closed for more than 10 seconds.
5. Remove the special tools and connect the pressure hose to the pump by tightening the hose union nut to the required torque.
Tightening torque: 55–65 Nm
6. Bleed air from the power steering hydraulic drive.
