    Ok i've had enough with this curtis sno-pro 3000...can someone tell me how does the selonids work on this plow? I've worked on meyers and western my whole life and this curtis is new to me.. heres what i can't figure out How the hell does this pump tell the valves to open and close? i dont get it should they spin on the shafts or vibrate? Should they be put on a certain way? I've been up and down this plow wiring fine,when i disconnected the head unit from the pump and hit up left and right oil shot out of tank from bottom hole so im figuring we have pressure? took tank off all clean inside so put that back together checked all grounds there good added even more just in case....took both plugs out of head and cleaned both springs and ball bearings which were fine to begin with...the other question i have is all thoses other allen key plugs on the head unit do they come out? i tried three different ones and they don't move....so again any help would be great thanks again ...

    It sounds like the selinods on the valve cartridges are bad have you checked them?

    Also did u mess with the valve cartridges at all? If you tighten them too much you can damage them

    No, like any other parker valve of this type, they just magnetize to move the plunger. Just like Western/Fisher/Meyer/Boss/Snoway/etc.

    When using the controller when lifting it powers the brown wire for the solenoid under the hood and powers the red wire on the coil on the plow.The same for angles powers blue left and white right. Any questions give me a call at 1-800-343-7676 ex3042.

    the only thing all the coils use the same is the orange wire for ground if they all stopped it would be the ground.

    Remove a coil and valve from the manifold. power up the coil and see if it produces magnetism if yes assemble the valve and coil on the bench and use 12 volts to power up the coil. see if the valve plunger moves freely. If the unit was left sitting with contaminated fluid it is possible that, yes, both those valves could be frozen. I've seen it many times with many manufacturers. maintainance is key.

    Can you mount the plow to the truck? You could just have bound angle rams.

    if so and you haven't already tried this, assemble the unit, mount it and take it out to a tree.
    Place the left side of the plow blade against the tree and give it a little power while angling left.
    Don't be abusive, often just idling into it will do it but sometimes it need a little gas

    Warning, the part of the packing that attached itself to the bore is still there and if the blade wasn't at full angle will eat at the packings during use, those rams are good candidates for a rebuild.
