    Long story as short as possible. I am fairly mechanically inclined but am tight on funds so don't want to mis-daignose.

    Bought it used over the summer. Played with it a few times and noted it sounded a little rough (FREAKING FORGOT TO CHECK THE FLUID!!!):dizzy:
    Went out to plow and started putting fluid in to top it off. Took a whole qt and was still not totally full. Plowed about 2hrs and it seemed a bit weak. Parked it, it was leaking like crazy. Got it home seemed to be done leaking so I seriously thought all the fluid might have leaked out. Woke up in the AM to the Exxon Valdez in the driveway (HOA will be thrilled at my stupidity I am sure!)

    I assume there is a seal that goes in the middle there? I am hoping that is the case. Since I gotta take it apart is there other stuff I should check,service or replace while I am in there?

    Thanks for the help. Also is there a good comprehensive post on diagnose and repair/service type stuff. I can service most stuff myself but know from experience how helpful advice from guys who have been there is. My plow is getting a little old (2004)but is in good overall shape. i just want to do whatever service I should as I am pretty sure the previous owner did not use it or service it to much.

    thanks,

    The more important question is you bought a used plow in the summer and didn't at least check the fluid let alone flush the system? Where are we looking on your pics for the leak? You could hose it down with brake clean and just play with the plow for a few minutes and see where it's leaking

    Stupidity noted. I honestly do not know what possesed me to not check the fluid.

    Non of the diagrams I can find seem to give me a break down of the pump/motor. I would wash it down but it is all dry except for near the bottom in between the motor/pump assembly. I assume this means there is a seal leaking between the two? I just figured if it was a common thing someone here would know. Or is it at all common to have something else leak where all that bolts together. Also it will drip steadily just sitting there even after the plow is dropped, system is off, etc.
    ?

    If you don't have your owner's manual,you can also look at Boss's site or Equipment Specialist's Inc. site which has all the schematics.I would first see after cleaning as already mentioned where it's leaking,then disassemble the pump so you can check and clean the strainer and sump.I'm sure B&B will chime in later,our resident underpaid expert on the Boss.:mechanic:

    If it leaks that much it should be easy to figure out, the motor side is dry (supose yo be) The seal kit is $38 comes with all orings and the filters

    If it's only wet at the very bottom then it can only be leaking from two places. Out the motor shaft seal (in the manifold) or from around the reservoir O-ring. Shouldn't take much to track it down after a little bath with some brake clean.

    Also while you're in there cleaning things be sure the breather isn't plugged up and therefore creating excessive pressure in the reservoir. Best bet is to simply screw it out, pop it apart (the top and bottom will separate) and clean it out too. Takes 5 minutes and will positively rule out an excessive pressure issue in the reservoir.

    Thanks gents,

    The main reason I posted was because the parts blow ups I could find did not show the motor/manifold breakdown. I think I will order a seal kit and dig in.
