'85 era Fisher Speedcast Problem HELP?

    Hey fellas,
    I bought an '85 F250 to plow a long driveway last spring. I'm working on getting it ready for when the snow flys. My problem is that the plow won't angle. I think the valves are working. When I push the stick back and forth the hoses move like they are getting pressure. I don't think that the fittings are clogged. When I push on the balls in the quick connects ,fluid shoots out. The guy that had it before me replaced the angle cylinders (not the raising though) so they should be fine. I was told that maybe the packing nuts are too tight. I assume that those are the big nuts at the end of the cylinder (where the rod comes out.) I was also told that messing with those can cause problems. Anybody have any suggestions.

    By the way,this is a great site.

    Erik

    Thanks for the offer, but all of that is working fine. I stopped by the local Fisher service shop and the only thing that they can think is that somebody left a "dust plug" or capin the fitting on the cylinder. Or sombody welded the plow when it broke the first time. I'm going tocheck both tomorrow when it's light :) DUH!

    Well, it was choice D "None of the above"

    I took the fitting out of the cylinder and took the cylinder off the frame. Both cylinders are frozen. They won't open or close, no matter how hard I try. I dropped them off to confused Fisher serviceman. He said he would call when he has a chance to look at them. I'll keep you posted. :confused:

    Likely hte packing froze up. Sorry I did not get to this earlier. Loosen the packing nuts and move the cylinders, as they free up, tighten the nuts back down.

    Thanks Flipper,
    My service guy said that hey might have some rust on the inside. He said with the new Low friction cylinders, they don't really have packing. He said it was a metal to metal fit. That sounds kinda screwy to me. If that's the case what seals the cylinder. Ah well. I guess he will either fix it or not. I just hope it doesn't cost much.

    If it is not a minute mount then they are not low friction. The old cable systems used packing cylinders. I will bet they have clogged with rust. Another reason to flush the system once a year.

    That's what I thought Flipper. My service guy said that the minute mount cylinders fit the old plows if they are the same size. I'm not sure if these are or not. I didn't replace them. The previous owner did. They are brand new last spring. I still think that the packing nuts are too tight, but we will see.

    Thanks for the opinion folks.

    OK I did not know they were replaced. They could be the new cylinders. They do fit.

    Well, It was the packing. The Nuts were just too d*mn tight. It's working fine now. Now all I need do is keep the thing from overheating. HAH!!!!
