I recieved my behlen power steering unit today and went to test fit and it is hitting the air breather tube running across the valve cover by about 1 inch. Has anyone has this problem before?? Also I have been looking in the archives here and other sites for the past few hours doing some research on this and have not found a picture that shows exactly how the valves, pump and hydraulic hook ups look. I have a owners manual and I&T manual that shows some pictures but does not solve my problem to why my pump is not fitting. Did they make different tubes or pump lengths?? My next question is that I keep hearing that a regulator / safety valve or priority valve is needed to run the PS. Did all tractors come equipped with this and how do I tell if mine did? I will take any information / ideas etc on this! This is one of the finishing touches on this tractor. Thanks to all in advance!
