    Plow
    Boss 8'2 steel V blade RT2 w smart hitch, no smartlock cylinders

    Problem
    Right wing will ALWAYS extend when asked

    Right wing will NOT retract.

    I have a stick and the old toggle switch controller, same results with both.

    Cylinder Problem???

    Every thing else works perfectly, just the right wing retract is stuck - but if you push on a curb it will retract.


    Thanks

    Just a little nudge on a curb and the it will take off on it's own? Or pushing all the way in on the curb?

    Could be a valve stuck,do you grease it up during the season? Tighten the spring a little

    Check the obvious first--your electrical connections to the valves and solenoids under your black cover.Then check for magnetism on that wing.If it's not that,it might be some dirt blocking proper hydraulic function in that valve.Fluid and screen clean?

    Mr Mud - have to push it all the way

    Grandview - yes, regular grease, but will tighten the spring.

    Tuney - extends perfectly every single time you try so it can't be electrical connection. Can extend into full scoop and retract the left side, so its not a seloniod problem. Fluid change done at beginning of season, which was about 15 hours of plowing ago this year.

    I was hoping it wasn't a valve, because I hate pulling them - always seem to end up replacing them. But considering purchased it used 3 years ago and have not done anything other than replace a broken spring last year - thats pretty good.

    Also check your cylinder on the plow where it is hooked up at the base to make sure its freed up.

    I would disconnect the hose from that cylinder first after it is fully extended(well slightly crack the fitting at the pump so it bleeds out) and then see if the spring will retract it. The spring should bring it back. If that doesn't do it tighten that one up and loosen the one on the cylinder, this would help eliminate the hose that way being collapsed on itself inside. MUD

    None of that means a thing. There's a separate valve for each individual function thus one faulty valve or electrical connection will only cause the loss of one function, up, down, extend, retract etc.

    Run the wing out and loosen the hose for it, if it retracts then it's a valve or valve activation issue (electrical). If it doesn't then the hinge is tight, the wing is bent or the cylinder is defective.

    hmmm, Ok good to know B & B

    The wing is not tweaked, the return spring has lots of tension. I will crack the lines tomorrow and report back on if it;s a valve or electrical

    My plow had that problem last year , I thought it was a valve or cylinder, but my dealer told me it was a dead spring. They put a new spring on and it works now. ( spring was not broken , just dead)

    Similar to B & B's suggestion, try swapping cylinders, and see if the problem follows the cylinder, or goes to the other side. Could also swap springs first and see if it is the 'dead spring' that was mentioned earlier.

    Sorry for the delay getting back, have not had time - but snow tomorrow so it was fixed tonight.

    Cracked the line on both ends and still could not push it in. Had to take the line right off - big pressure build up was in it.

    When we removed the line and the wing snapped back (definately not a dead spring). Went to Napa to have a replacement line made up but they tested it and it was still good.

    Re-installed the old line - works flawlessly now. Must have been a build up of crap in the line at the valve which blew out. Cleaned and flushed the fluids just to be sure.

    Going plowing tomorrow and instead of a back up/clean up truck it is going out on a route to test it.

    Thanks all!!!
