    I have an older western plow with the cable controls. The problem is it doesn't seem that there is enough travel in the cable controls to make the thing go up and down like it's supposed to. Left and right works fine. This has been an ongoing problem for the past couple seasons and it seems as if now its so bad i cant use the plow. I can still raise and lower it by getting out and mokeying with the cable but want it fixed right. Could it be the lift valve?check valve? This plow is very old and has never been rebuilt so something seems worn out. Can someone steer me in the right direction towards the problem please. Thanks, Bob.

    Some things you might want to check;

    A)Check the cables to see if they are stretch..Is so replace the cables

    B) Check the "lift ram" packing nut. If might be too tight, or the seals might be dry. If it too tight, loosen the packing nut slightly. Also check the shaft to see if it has pits around the shaft (rust spots verser chrome)
    If it is dry, then use some hydraulic fluid on a clean rag and (with the ram up) wipe it on the ram itself. Then drop the plow, lift.Then do it again, making the ram slippery.. Lower it again.. If it works, you resolve the problem

    C) there is call a "adjust lift valve". Follow the instructions carefully.

    lift valve

    Its not the packing on the ram I have replaced it a couple seasons ago and I can push the ram down by hand when the cable is pushed into the motor far enough. Cables are good too. I will have to replace and readjust the lift valve i guess. The screw is stuck and will take some heat from a torch to get it out so the current valve and o rings will be junk by the time i get the screw out. Should I replace anything else? Should i do the check valve at the same time? Thanks for the help! Bob.

    Yes..........Don't heat it up to were it get really hot...Just warm it, or use blaster and see it that will loosen the rust up and may free the screw........You did down load the PDF?? that will show you everything from a break down point..

    Check the spool in the lift section. Disconnect the cable and make sure the spool turns freely and completely both ways. I had a stiff spool on one a few years ago and that was causing the cable to seem messed up. Have you flushed the system recently? You'd be surprised at the water that gets in there and the problems that it causes. Good Luck

    Yeah it has pretty fresh fluid in it and it is the blue stuff. Its not the shaft thing either as it moves feely. Im gonna order parts for the lift and check valve monday. I would just take it apart first but the screws are rusty and Its going to be a tuffy to get it apart. Ive downloaded the manual and hope im headed for a fix. Its been acting funny for a few seasons so it would be nice to having it working well. Thanks for all the help.

    Be careful when you're doing the adjustments on that lift and check valve. That blade doesn't care whats under it when it drops. The new lift valve will be plastic, carefull adjusting it so it won't strip. Good luck.
