I have a single block U thats haunting me. With the line screwed out of the block I have oil flow but no pressure. I have cleaned out the screen on the bottom of the pump, changed oil and filter. Droped the pan and changed the oil pump, changed the compleat oil filter assy, and looked for a spun bearing. I have the screw on the regulator valve bottomed out and still no pressure. Has Anyone ever ran in to this? Thanks.

Yes I found a stuck check ball in the filter base is what caused mine to do this.

You are most welcome! It is most like from condensation that causes that to happen while tractor is not in use.
