    Hi All, thanks in advance for any advice you can provide. The hand throttle in my '74 580B does not work. Its hard to move and there is no change in RPM when you force it a bit. I was looking online at a diagram and it looks like the bracket the hand throttle attaches (#2) to points up...

    1974 Case 580B Ring Gear

    Hello Hello … the old Case made a baaaad sound the other day so I tore it apart and found the ring gear is not happy … can anyone give me the basics on replacing it? I’d imagine start with pulling the rear axles (the easy part) but then how do you get the ring gear off of the brakes/diff? Any...

    Relief valve? Rebuild?

    Hey guys, My 74’ Case 580B has been leaking from this for a while ... I unthreaded it and replaced the o rings last year, but it’s leaking internally from under cap/c clip ... is this a relief valve and how difficult is it to repair? I can’t seem to find any schematics on it

    I've read a few posts on here, about the Case 580ck and 580b Hydra leveling system problems. It seems that the cylinder on the right side tends to break the ram just below the pin. Mine had now done the same thing. I've read the this cylinder can be bypassed. Is this accurate and if so, how...

    our 1969 case 580b hydraulics quit working while trenching. HELP

    We are not familiar with where to start with diagnosing. The previous owners let things run down quite a bit, but we felt the price was right for our needs so bought it traveling through two states to pick it up. Back to the problem at hand: We checked to see that the input shaft on the front...
