    To clarify, which direction can it be pushed by hand? Left, right or either way? And which check valve did you change? The pilot check in the top of the valve block? What about the ball and spring under it?

    It's either a blown cross over valve or a damaged pilot piston or it's ball, seat or spring. You mentioned that you replaced a "check valve", what exactly did you replace? If it was the pilot piston you're referring to, did you also check/replace the ball, spring and it's seat as well?

    I ended up buying a one peice cross over releif and put it in tonight and it works fine. I didnt mess with the center screw on the 1 peice cross over,plow turns both ways and holds now!! whats screw for and should i mess with it? is it for pressure like the orig?

    Correct, the screw adjusts the relief pressure just like the original one. If you don't have the pressure gauge to properly check and if needed adjust it...leave it alone and try it under actual plowing conditions as is. If it seems a little weak to hold you can adjust it slightly in small increments from there. Not really the right way to do it but it's a reasonable substitute as long as you don't over adjust it.
