Does anyone have the secret on how to remove the pressure regulator relief seat in the Touch Control hydraulic block? There is an o-ring on this that I would like to replace while I'm rebuilding this unit. The relief seat as you look down in the whole it is in, about 2", has the 9/16" ball in the center, and looks like you could take a wide, 1", screwdriver and turn the seat out. The ball is spring loaded. I'm not sure that is correct and am looking for ideas. The block has 351-981-R1 on the side. If you have a parts book it is part # 352 025 R1 and reference #26
