    Hey, I have a slow moving mm plow and today I pulled the motor and added fluid. That didn't help though. Would you mind walking me through the procedure for removing the pump(yours looks just like mine) and pulling the filter. I am thinking the filter is below the pump and it look like you just had to remove two bolts to get the pump out, but I want to be extra sure since we have a storm coming this weekend.
    Thanks, Imac

    If your pump is the same style pump as diesel dust (SEHP pump), then remove the drain plug and drain the fluid from the reservoir (tip: I simply remove the pump assembly from the headgear, remove the motor, and then dump the contents into a bucket to be disposed of properly.

    Once you have the fluid drained you'll see the actual pump on the bottom of the reservoir. Note how it is situated in there before removing. you can reinstall it backwards and you won't realize it until you try an mount the motor to it. Now, 2 of the 4 corner bolts actually secure it to the reservoir, I forget which ones, but there diagonal from one another. if you need to, you can remove all 4.

    Now remove the pick up filter and replace (part # 7053). inspect the large o ring on the under side. replace if needed (part # 5821).

    Now, clean the reservoir with a can of brake cleaner and lots of shop rags. Once it is clean, re install the pump and motor. You'll need to remove the old motor gasket, use a razor to scrape away any stubborn pieces. Replace with a new gasket (part # 5822), reinstall motor and wires and our done.

    If the fluid, reservoir, and filter were extremely dirty it is a good idea to flush the system after you get it back together. See page 5 http://www.fisherplows.com/pdfs/26404_061504.pdf.

    :eek:holy hell thats bad. I just replaced my pump yesterday in one of the trucks because it was moving slow. we did a system flush in the fall but it looked real bad when we opened it up. The pump was starting to deteriorate. shavings everywhere, brown oil. Replaced the whole thing and its good as new.

    In case anyone else is doing this don't forget to flush out the angle cylinders otherwise you'l clog the new system right up again.

    Great write up Ryan. I'll have to save it for the off-season.

    slow moving

    hello-if you got that much metal on the filter check your aframe to see if its bent-putting load on angle pistons and scraping inside piston tubes--and clogging filter
