Ok, just had Power Steering pump and pedestal overhauled due to no power steering at my local JD Dealer. It is all back together now, and the first problem was leaks so I tightened all the lines and bolts up, and now it's dry. Second problem was no power to the left, which I fixed by centering control valve assembly. Now I have power steering both directions; however, the assist is non existent at slow idle. If I throttle it up to fast idle there is a fair amount of power assist, which I could live with, but I would like it to steer easy at slow idle. This leads me to what I've done to try and rectify the issue. 1. I have tried adjusting the flow control screw to no avail. 2. I have tried to shim the relief valve to increase pressure. I have .180" of shim in now and has done nothing to increase pressure from the original .120" of shim. My best lock to lock pressure is like 1000-1100 PSI and you have to wait for the pressure to build that high. I am sitting at around 500 PSI when I turn the steering wheel left and right. I have a new relief valve spring ordered and will try to add pressure latter in the week, but I'm not convinced this will help. Any Ideas or suggestions is much appreciated. Also, how easy should the steering wheel turn at idle? If memory serves me right, the old 730 we had on the farm back in the day turned really easy.
