Unimount problems

    I have a Western Unimount plow that I use to plow my own driveway and a few others. About 2 weeks ago the plow stopped going up or angling. The motor was squeeling when I raised or angled the plow. I replaced the motor with a brand new one and it worked fine for two plowings and started doing the same thing. The fluid level is fine. I checked the electrical and found corrosion in the 12 pin connector so replaced both sides of the harness with new harnesses. The plow worked great again for two plowings and is now doing the same thing.

    The plow will raise very slowly for a few inches and the motor stops. If you release the trigger and press again it will raise a few inches and quit again.

    Any ideas would be helpful. I live in Western New York and a dead plow is not an option.

    Thanks
    Paul

    when was the last time you change the fluid?
    You might want to check the screen to see if there any slug or clog..

    This should be the first step..

    I always change the fluid just before winter, however when I replaced the motor the fluid was exposed for a short time, so that may be a possibility. I am assuming that the filter you are talking about is the one inside the hydrolic cylinder?

    sounds like a plugged filter to me.

    Yes it the filter attach to the pump. While your in there, check the pump, it might be jamming up. Just keep in mind there an "o" ring on the bottom of the pump. It might be bad and seeping fluid?

    Thanks everyone. I'll pull it in the garage tomorrow and check it out. I'll let you know how I make out.

    Ohh forgot and not 100% sure you have one as some I have seen do and some don't but there may be a magnet in the housing too. If so make sure to clean it off.

    OK... I pulled the truck into the garage this morning and took off the motor and drained the fluid. I took off the screen and it was pretty dirty. I cleaned out the entire chamber and the screen and found that magnet laying on the bottom covered in sludge. I cleaned that off too. I put everything back together and it works great now.:D

    Thanks everyone for the great advice. They are calling for snow the next several days and I didn't want to be without the plow. :)
