OK, so I removed the whole unit from the tractor and took it apart. The screen was collapsed and torn so I cut it off the orifice and chucked it in the garbage. There was no roll pin or check ball. What exactly is the purpose of the screen anyways? It seems to me it would be better if a small amount of garbage passed through than to have the screen plug up and wreck your hydraulic system. The orifice size was still .031" and I left it at that. The o-ring on the piston looked good. I polished out the bores good with some 600 paper.

What is the small hole that is drilled in the piston at about 45 degrees to the axis of it? I was only able to get a piece of wire a small ways up it.
