    i have an older hydro 8' fisher on my 97 F250. the problem is, it doesn't want to move up,left,right too fast. it doesn't sink if i leave it up even with the truck turned off. i just put it on this year new pump full of dexron III, new belt-not slipping. my guess is air just wondering if anyone else had any idea.

    the plow is old, but new to the truck. when i put it on this truck i bought a new pump-the one that came with the plow was no good-it runs slow when i start plowing & it actually seems to get slower the longer i'm out-although that may just be in my head.

    This is true - the hotter your engine compartment gets, the thinner the oil gets and the slower the pump will move. The hydro setup on my 1989 chevy takes about 5 seconds from bottem to top and 6-8 seconds from one side to the other. This is when its fully warm.

    They are just incredibly slow - not much you can do to speed them up
