    I HIT FROZEN HUMP WHILE DRIVING BACKWARDS WITH THE LEFT WING ON A 8.5 V PLOW WHICH RIPPED THE CYLINDER APART. I REPLACED THE CYLINDER AND NOW THE V AND SCOOP FUNCTIONS DO NOT WORK RIGHT. IF I PUSH FOR THE SCOOP IT GOES TO V. IF I JUST USE AS STRAIGHT BLADE IT WORKS FINE. WHEN I PUT THE CYLINDER BACK ON IT WORKED FINE FOR THE FIRST FEW TIMES I TRIED IT BUT THEN IT STARTED TO NOT WORK CORRECTLY. I EVEN TRIED SWAPPING THE FRONT AND REAR LINES ON THE CYLINDER THINKING I SWAPPED THEM WHEN I PUT IT BACK TOGETHER. ANYONE EVER HAVE THIS PROBLEM?

    Check to make sure that the solenoid under the hood didn't rattle loose. My solenoid came loose and lost its ground. It cause mine to have a mind of its own. Also check to make sure have the proper amount of fluid in the system.

    There has to be a solenoid under the hood. That's what makes the plow work. Try checking the screen in the pump.

    Ejam,

    You have a Valve on the pump that is not functioning properly. You will need to check a service manual, call the dealer or someone with a manual to do the full diagnose on which valve. It sounds like the trigger valve for the scoop function is jammed. If you tore out a cyl you probably have pcs of metal that worked into the valves and this causes the jam up. If you want to call the shop on Monday or try tommorow after 1:00 I'll be there for a while and can walk you through the check out.
