Checking the hydraulic pressure in the V8 (Range Rover 3)

Before disconnecting the battery, make sure that all requirements and conditions contained in the section on disconnecting the battery are met.

GENERAL INFORMATION, Precautions when working with electrical equipment.

Pressure check

1. Place the vehicle on a lift.

2. Disconnect the negative terminal from the battery.

3. Pump out the working fluid from the power steering reservoir.

4. Remove the protective shield.

EXTERIOR PARTS, REPAIR WORK, Engine protection - front.

5. Place a suitable container under the power steering pump.

6. Loosen the union nut, disconnect the high pressure line from the power steering pump and separate the sealing ring.

7. Install the LRT-57-034A adapter onto the high pressure nipple of the power steering pump.

8. Connect the LRT-57-035 adapter to the existing high pressure pipeline.

9. Attach the LRT-57-002 tube to each adapter.

10. Connect the LRT-57-005 pressure gauge to the LRT-57-001 test valve.

11. Connect the LRT-57-002 hoses to the LRT-57-001 valve and tighten the connections.

12. Connect the negative terminal to the battery.

13. Check for any leaks of power steering fluid from the steering system and test equipment connections.

14. During testing, maintain the required level of working fluid in the power steering reservoir.

15. Open the test valve and start the engine.

16. With the engine idling, slowly turn the steering wheel to the full lock position and hold it.

17. Repeat the operation for the other extreme position.

18. Record the pressure readings in the system.

19. With the engine idling, release the steering wheel. The pressure in the system should be less than 7 bar.

20. If the pressure is higher than specified, it indicates a malfunction.

21. To determine if there is a fault in the pump or in the steering gear assembly, close the valve for a maximum of 5 seconds.

CAUTION: Keeping the valve closed for longer may damage the power steering pump.

22. If the pressure values are outside the limits specified in General Information, replace the power steering pump.

23. If the maximum pressure in the hydraulic system is within the norm, the fault may be in the steering mechanism unit.

24. Complete the check, stop the engine, disconnect the negative cable from the battery and pump out excess working fluid from the power steering reservoir.

25. Dismantle the test equipment.

26. Clean the power steering pump and pipe connections.

27. Install a new sealing ring on the end of the pipe, connect the pipe to the power steering pump and tighten the high-pressure nipple nut to a torque of 25 N·m.

28. Remove the container from under the power steering pump.

29. Empty the container from the working fluid and clean the container.

30. Connect the negative terminal to the battery.

31. Add working fluid to the required level and remove air from the system.
