I posted on here several weeks ago that my 1370 only had 1600 psi hydraulic pressure on the remotes. I put a shim under the relief valve spring and that put it up to 3000 psi. What I didn't do was get a smaller shim to lower the pressure to the factor spec of 2200. I been using it to spray and disk and had no problems. I just make sure I'm easy on the remotes and don't hammer on it when cylinders bottom out. My brother was helping me today disk and he used it about 2 hrs and It lost all but 500 psi on the remotes. Power steering is fine, ps shifts fine through all gears and it still pulls that 25ft disk just fine. It just won't raise it up. I took out the relief valve springs to see if one may have broke but they appear to be fine. I tested the hydraulics in all speeds of the power shift including reverse and with the inching pedal down, no change. I talked to a guy today and he thinks my relief valve is malfunctioned somehow. Any suggestions on what to do next would be much appreciated. Thanks for taking the time to read my post.
