    Another note: Make sure to change the fluid if you haven't yet this season. Moisture accumulates in the fluid through the fall, when warm days and cool nights build alot of condensation. When it gets cold, the fluid will freeze up or get too gelled to flow properly.

    Don't use ATF, even though there may be a sticker on the case that reads something like: "Change ATF yearly". ATF is great for the old underhood pump/reservoir systems, where engine comartment heat kept it flowing nicely. It really doesn't do that well in external systems when the temps really drop. Fisher Hydraulic fluid or the low temp stuff from Buyers seem to work well for me. I can get either easily around here. If you can't find it, check your local NAPA.

    Here's a good thread with pics from another member here. http://www.plowsite.com/showthread.php?t=93081


    Will you need a new gasket? Maybe is the best answer I could give. Were it me, I'd at least have one on hand when I took it apart in case it ripped or just looked wiped out.

    When you get the filter out if its covered with a fibrous looking material its time to rebuild the unit and replace the angle cylinders. The material you see is the seals falling apart. You can flush it out, but it always seems to come back until we rebuild the unit.
