7. Syphon PAS fluid from reservoir.
8. Position container to collect PAS fluid spillage.
9. Clean steering box pipe pipe housing.

10. Remove bolt securing pipe clip to steering box. 

Leaving the feed pipe from PAS reservoir in 
place, release clip and PAS cooler pipe from 
steering box. Discard lower 'O' ring.

11. Fit LRT-57-041 adaptor to steering box.
12. Fit PAS cooler pipe to LRT-57-041, align 

retaining clip and tighten Allen bolt to 25 Nm (18 
lbf.ft).

13. Hang pressure gauge in a safe position under 

bonnet.

14. Remove PAS reservoir filler cap, fill to level 

indicator and refit cap.

15. Connect battery earth lead.
16. Start engine and allow air to bleed from PAS 

system by turning steering from lock to lock. 
Stop engine and check PAS fluid level.

17. Ensure steering system and test equipment are 

free from leaks.

18. Open test valve on LRT-57-001 and start 

engine.

19. With the engine at idle, slowly turn the steering 

wheel and hold on full lock.

20. Note the pressure reading on LRT-57-005.

21. Repeat the pressure check for the opposite full 

lock.

22. Test pressure should be between 21 and 62 

bar, (300 to 900) psi. Dependant on road 
surface.

23. With the engine at idle, centralise the steering 

wheel. Pressure should read 7 bar (100 psi) or 
below.

24. Pressure outside the above tolerance indicates 

a fault.

25. To determine if fault is in steering pump or 

steering box, close the valve on LRT-57-001 for 
a maximum of 5 seconds. Pump damage may 
occur if test valve is closed for longer periods.

26. If gauge does not register between 75 and 103 

bar, (1500 psi), (maximum pump pressure), the 
pump is faulty.

27. If maximum pump pressure is correct suspect 

the steering box.

28. On completion stop engine, disconnect battery 

earth lead and syphon fluid from PAS reservoir.

29. Remove test equipment from LRT-57-002.
30. 
Remove bolt and clip from steering box.
31. Release PAS cooler pipe from LRT-57-041 and 

discard 'O' ring. Leaving PAS reservoir oil feed 
pipe in place, release LRT-57-041 from 
steering box and discard 'O' ring.

32. Fit new 'O' rings to PAS cooler pipe.
33. Fit PAS cooler pipe to steering box, align 

retaining clip, fit bolt and tighten to 25 Nm (18 
lbf.ft). 

34. Remove PAS reservoir filler cap, fill to level 

indicator and refit cap.

35. Clean chassis member.
36. Fit splash shield and secure with screws.
37. Connect battery earth lead.
38. Start engine.
39. Start engine and allow air to bleed from PAS 

system, by turning steering from lock to lock.

40. Visually check PAS system for leaks.
41. Check power steering fluid, if aerated, wait until 

fluid is free from bubbles then top-up reservoir 
to 'UPPER' level mark.

42. Visually check PAS system for leaks.
43. Dismantle test equipment.
