had problems with my plow the other day, went out, noticed it moving a little slow, but didnt have time to mess with it. i figured i'd limp it around, and address it later. went to plow my first driveway, pulled in, drug out from the garage, then turned the truck around and pushed it out of the driveway. when i got to the other side of the road the blade wounldnt lift. first thought was frozen pump, so i brought it in the house and set it in the basement to thaw. brought it up tonight, drained the fluid, and its a grey color. i know, first thing you're going to say is "it should be red" well, the maintnance guys at work and i were talking, and they run hydraulic jack oil in the plows at work, and have great results with it. it is clear. so i decided to try it in mine. when i saw the fluid, i decided to pull the motor, and have a look at the filter. im glad i did! the filter was covered in a slimy film, and appeared to be almost completely clogged. now about this time last year i had to put a new pump and motor in it, so this pump is only a year old. do you guys think that i should be ok with this pump, and it just had a clogged filter? or do you think im in for a new pump? is there any way to check it without a pressure gauge, as i dont have access to one until Tuesday, and i'm probably going to need the plow before then.
