    If i hot the pile with the right side of my plow my plow will angle to the right side. i dont think it is a leak in the cylinder. although i will soon replace the right cylinder simply because it is old.

    could this be because of a angel valve?

    first thing to do is replace the cylinder. as old as it is its dangerous anyway. last one had the retainer ring simply shatter. shrugs.

    Good, that's what stops it from breaking.
    Not being sarcastic.
    Its working correctly.

    You're ramming the snow pile too hard.

    so its the relief valve. ill compare it to the other side and see how it goes and see about hitting piles softer when its on one one side.

    its called a cushion valve. it is design to give when striking an immovable object. there is one for each side, it is adjustable on many pumps.

    go to western website under service, then publication library. find your model plow/pump and see what it says.

    says theres only 1 proper adjustment which comes to 3500 lbs. could the spring be old and worn?

    This was my guess as well.

    do exactly what the manual tells you to do.

    Ty. I read it over it looks to be a simple process. If the other side isn't as weak ill just buy a brand new valve and install it as the manual describes.

    The problem is in my inexperience I'm not sure if its a mechanical thing or if I simply am hitting too hard as stated

    I can find out next snowfall. Hopefully tonight

    well. the welds havnt broke yet. iv inspected them and while i kidna feel i should redo some of them, there are no signs of weakening.

    but its still quite possible im hitting too hard. thsi one lot i come up to the hill at an angel. so the force that woudl normall be on both check valves is on one. is probably what its doin.

    ill figure it out. if hte other side is the same slow down. if its not the same, ill jsut buy a new valve and replace it. looks easy enough.

    well. lightly pushed a pile and it still angled in. so is either the cyl or the valve. ill replace the cyl. just in case. stil does it get a brand new valve.

    ty for the help all

    Get a valve. A cylinder won't move unless its leaking, or the seals are bad internally. Since you said its not leaking, and plow cylinders are one way,,,I say the psi relief, or crossover,

    True. but the cyl is so old i want to replace it before it explodes like the other one did.

    i assume the relief valve is gone bad. how can i tell if it is that or the cross over?

    I just had this problem and replaced the crossover valve. Works fine now. Good luck!

    Yeah, that's an old plow and I don't see a crossover valve. Looking at the diagram it would seem like the cushion valve would be bad. It's just a spring holding a ball so the spring could be worn out.

    It most likely a cushion valve. They are made for when you hit something hard enough the blade will angle with the pressure so you dont damage any thing.

    yes, it's page 4-4 in that mechanics guide. (or the 28th page of 48)
