Fluid out the vent?

    Plowed for a few hours last night and this morning. Fluid seems to be leaking/blowing out the vent on top of the pump. Should this be happening?

    Was it over filled? or filled with the plow raised?

    Any other symptoms? Is this an old style brass vent or the new plastic duck bill?

    I don't believe it was over filled. The plow was lowered when filled. Thanks for the reply!

    It's a brand new plow. It is the plastic one. The plow does seem a little slow to raise.

    Return line or defuser at the end of the return line may be off.

    How would I go about determining this?

    not going full up, as in all 10" of stroke out of the cylinder.

    It's going all the way up. Just seems slower, maybe it's me. I'll post some pics of the leakage.

    Here's the pics. It's sorta hard to tell. The ice is accumulating again. You can see hints of blue.

    It may just be slower because the fluid level inside the reservoir is now lower than full. Did you check the level at all? On the other hand, it may be the fact that the reservoir is overfilled that caused fluid to spill out the quill. Kind of difficult to diagnose.

    The fluid was a little low. Should you be able to turn that vent? i turned it a little bit to tighten it. I couldn't tell if it leaked anymore because the snow was already blue there and didn't want to touch it only to get it all over the steering wheel.

    This air vent is what controls how fast the blade drops when in float mode. The tighter it is, the slower it drops, IIRC. I keep mine tight either way.

    are you filling up with all cylinders retracted? Lift must be all the way down and plow in vee position.

    That is how I fill. I called the dealer today and he called fisher on it. They said there isn't anyway it could be leaking out of the vent. hmmm

    I don't know why they told you that.If the baffle's have fallen off the return pipe's or the pipe's themselves come loose inside the reservoir. it could very easily blow fluid out the vent.

    Drain the reservoir and remove it.The return pipe's will be sticking straight up and will have a "diffuser" on the end of them (if their still there). Also, judging by the last 2 pics you posted it look's like maybe the ice build up could be restricting the vent.
