All Models

10. Fit hose LRT-57-022/3 to each adaptor.
11. Fit pressure gauge LRT-57-005 to test valve LRT-57-00.1
12. Connect hoses LRT-57022/3 to LRT-57-001 and tighten all unions.

Test Procedure

13. Ensure steering system is free from leaks and maintain maximum fluid level during test.
14. With the test valve open, start the engine.
15. With the engine at idle, slowly turn the steering wheel and hold on lock.
16. Repeat pressure check in opposite lock.
17. The test pressure should be between 27 and 55 bar, dependant on road surface.
18. With the engine at idle, release the steering wheel. Pressure should read below 7 bar.
19. Pressures outside the above tolerance indicates a fault.
20. To determine if fault is in steering pump or steering rack, close the test valve for a maximum of five seconds.

CAUTION: Pump damage will occur if test valve is closed for longer periods.

21. If the gauge does not register between 85 and 97 bar (maximum pump pressure), the pump is faulty.
22. If maximum pump pressure is correct, suspect the steering rack.
23. On completion, stop the engine and remove test equipment.
