    I have a 2009 8'6 pro plus, the passenger side piston, the end nut with gasket came loose and leaked out hydro fluid. (in blue) anyway its stopped leaking and I put over 1qt of fluid in and now it seems like its loosing pressure? when my guy was plowing the blade would not stay straight for him at all.

    If anyone can help we're supposed to get hammered here tonight! :eek:

    it has some air left in it. leave the plow down, fill it full. leave it down. angle all the way 10 times. fill it again. leave it down. angle 10 times more and fill it again.

    by the way leave it down.

    It may well be air in the system but if purging and topping up doesn't resolve it you may have some dirt in a valve. Dirt would prevent the valve from closeing completly allowing fluid to escape under pressure when pushing snow.

    Why do you call the fluid hydro? I have seen this several times on this site. Hydro is means water ie" hydrate or hydro electric = electricity generated as water flows down from a dam through a turbine. The blue Western fluid is a petrolium distilate.

    here in jerzey we talks proper like. no say "you'all"

    by the way to stay somewhat on topic I tried what you guys suggested and the blade seemed to be a little faster however the pistons were still "mushy" when pushing hard packed ice.....thoughts? i looked in there and notice a little bit of foam but not much and did you what you guys had suggested again...i really don't want to open this thing up if i don't have too...

    If you don't want to open it up then just keep running it. If it is just air in the system it will work it's way out. The only thing that can make it mushy is air. If it leaks back when you are pushing then it could be bad check valves or a pressure relief valve that is set too low allowing fluid to leak back to the reservoir. It's not leaking any more right? If there is fluid leaking out it is possible for air to leak in as well.
