    I have a 861pp and the issue I am having is the plow works back/forth wings work but the issue is when I lift the plow up it doesn't stay up. The plow starts to drop. I was wondering if it can be a solenoid. All fluids are fine.

    Sounds like a valve issue. Could be debris in the system and caught up in your lift valve. Figure out which one it is and clean it thoroughly. May be a spec of metal, cylinder leather, or packing material causing the issue, could also be a bad valve. Clean first. Remember your hydro valves are not holding anything up until under snow load and you may have an issue there as well but don't realize it. Solenoid runs the electric motor and should not have anything to do with this issue. Been down this road with other electric hydraulic plows.

    I took all the valves out and they dont seem to be caught up due to me moving them with a small screw driver. The only reason why I think its a solenoid is it has power to it but when I try and drop it, it loses power and valve dont move.

    Solenoid is a pretty cheap part. Put in a new one. If that doesn't fix it you have a spare which is a good idea anyway.

    It won't fix it, solenoid has nothing to do with it. And is it ph1 or 2. You never answered

    Sounds to me like your pump needs to be rebuilt. Most notably the lift ram packing..

    Please stop just throwing ideas out there. None of you have attempted to diagnose this issue. We need to have some basic information first. Then we can direct you to the most likely issues and help you diagnose them.
    Herm : I don't know what piece you are really referring to when you say "solenoid" but coils and motor relays (solenoids) are easy to test before replacing. A coil will magnetize when energized and a motor solenoid would have nothing to do with this problem.
    PALS : What plow are you working on?

    Drop speed control?

    If you have it too slow, it won’t drop, is that true for the flip side?

    If plow 2005 or newer:
    Test number 1: set the plow down and turn the flow control knob all the way in clockwise. Be sure the knob bottoms out and does not just hit the jam nut. Then raise the plow. Does the plow stay up? If yes. The problem is at the s5 float valve. If no. The problem is within the lift cylinder or you have oil spraying on the floor.

    Bliz i did that and it did stay up. I am going to change out the s5 valve. I wasn't sure if it was the s5 valve or s8.

    Now open the flow control valve so the plow again drops after raising.

    S8 only effects the rod side of the cylinder. The base end of the lift cylinder would still hold the plow up even if the S8 valve was stuck in the shifted position. So we can eliminate it as a cause.

    Confirm that you do not have power/magnetism at the s5 coil before replacing the valve as a short in the harness would appear with the same symptom. To confirm, simply remove the coil and raise the plow. If the plow stays up, you have an electrical problem. If the plow still drops then you have confirmed the valve to be faulty.

    I picked up a new tool to disassemble valves at menards the other day. Couldn't beat the price, it was free after rebate. :mechanic:

    I'd recommend disassemble and cleaning of the valve before replacement.

    So will the cams on that grab the smooth part of the valve? I just wrap the smooth part in some rubber and put in the vise. How do you disassemble?

    I have a set of stud pullers that work excellent for this. This crescent wrench is the same principle and since it was free I figured I would try it.

    All fixed guys thank you all for the help. The valve was the issue.
