    Ok - just installed my new ( used ) speedcast system on my pickup.

    With the plow off , while Im driving around town ... the lift piston creeps up to the full lift position and stays there until I mess with the joystick and manually push the piston down by hand.

    the joystick isnt in the up position at any time.

    Whats the deal ?

    I heard tell of this same legend in speedcast history. I believe it was the reason so many would bungee the lift arm down to the frame. I never had a problem with it, nor did the 1976 that my grandfather ran for 20 years.

    If it is the cable operated ones that go to the valve assembly then the clevises have to be adjusted where the cable attaches too. You have to find the "middle" of up and down on the valve by adjusting the clevises. This is why they are threaded. That is if your setup has the seperate old style spool valve.

    If its creeping up then at some point it will reach the end and then you are putting a lot of strain on the belt drive pump, shortening its life. Having the belt on now is not doing the pump any good as it is.
