STEERING ADJUSTMENTS 57-21 13. Remove bolt from steering box pipe retaining clip. Leaving the PAS reservoir oil pipe in place, 14. Fit tool LRT-57-041 to steering box housing. retaining clip to pipes and tighten bolt to 24 Nm 17. Connect test hoses LRT-57-002 to LRT-57- 041 and tighten unions. Ensure all pipes and 18. Hang pressure gauge in a safe position under bonnet. 19. LHD only: Fit turbocharger intercooler feed pipe and vacuum connection and fit PAS 20. Fill PAS reservoir, connect battery earth lead. Start engine and allow air to bleed from PAS 21. Ensure steering system is free from leaks and maintain maximum fluid level during test. 22. Open the test valve on LRT-57-001 and start the engine. 23. With the engine at idle and normal running temperature, slowly turn the steering wheel and 24. Note reading on pressure gauge. noting the reading on the pressure gauge. 26. The test pressure should be between 21 and 62 bar, (300 to 900 lbf/in 2 . Pressure will rise to 62 bar (900 lbf/in 2 ) when held on full lock. 27. With the engine at idle, centralise the steering wheel. Pressure should read 7 bar (100 lbf/in 2 ) or below. 28. Pressure outside the above tolerance indicates a fault. 29. To determine if fault is in steering pump or steering rack, close the valve on LRT-57-001 30. If the gauge does not register between 75 and 103 bar, (1500 lbf/in 2 ) (maximum pump pressure), the pump is faulty. 31. If maximum pump pressure is obtained, suspect the steering box. 32. On completion, stop engine, disconnect battery earth lead and syphon fluid from PAS reservoir. 33. LHD only: Disconnect multiplug from MAF sensor, remove air intake hose clips and move 34. LHD only: Release PAS reservoir from mounting, for access to turbocharger 35. Remove test equipment from tool LRT-57-041. and discard seal. leaving PAS reservoir oil pipe |
