    Case 580CK: drain plug for hydraulic system?

    Thank you!! I'd been out grubbing around underneath the loader and found the drain plugs. I wasn't sure about the procedure, so now I'm squared away.

    Case 580CK: drain plug for hydraulic system?

    I want to put fresh hydraulic fluid in my 580CK, and on many of the online fora the consensus seemed to be that there was a drain plug in the loader frame. If there is, I haven't been able to find it! I hope someone can point me in the right direction, and also to verify that once I've drained...

    Rebuild swing cylinders 580-CK

    Well the cylinder is apart now and the rod at the shop getting rebuilt. The issue turned out to be a very very small "ridge" just inside the barrel from the gland, where the piston didn't travel. Maybe 1/32" and irregularly traversing the circumference of the barrel, it was holding back the...

    Rebuild swing cylinders 580-CK

    I put it all back together and the cylinder went in and out just fine, except for a little jerkiness, which I think is to be expected since the barrel was mostly filled with air. Worked it in and out a couple of times--I don't think it had moved from where I had it apart the first time. Now...

    Rebuild swing cylinders 580-CK

    The swing cylinders operated normally before I began the project; they both leak pretty badly though. > You need both hoses off of the cylinder you're working on, but regardless there it should rotate. There are flared connectors on both of the swing cylinders on the seat-side (or inside) of...

    Rebuild swing cylinders 580-CK

    I went back out and screwed the gland nut in about 75%. Eye will still not rotate with a 30" 1/2" breaker bar, and when I push the eye back towards the pivot pin it does not appear to have moved at all either in or out since I pulled the pivot pin out, i.e. the pivot pin slips right up through...

    Rebuild swing cylinders 580-CK

    Sorry for my imprecision: the hoses were off and clear of their fittings.

    Rebuild swing cylinders 580-CK

    I got the gland nut wrench, and the nut basically turned right off. I loosened the hoses at the "inside" of each of the cylinders. That's when the fun began. I cannot *budge* the rod. I hooked it to the back of my pickup and quickly saw that the clutch was going to go before it moved. I...

    Rebuild swing cylinders 580-CK

    I went out a bit ago, while I'm waiting on the gland nut wrench, and figured, "Later on I'll have to get the pivot pin back through the swing cylinder eye to hook things back up. Might as well see if I can do it now." Well, I cannot. The pin pushes up with no effort through the bottom of the...

    Rebuild swing cylinders 580-CK

    Thanks for the quick response. I realize in reading your reply that I neglected to ask this: would this go better with the boom up and "crowded," or stretched out fully, or somewhere in between? I understand it will be a bit of a task to get the repacked piston back into the barrel, and if...

    Rebuild swing cylinders 580-CK

    This is my first-ever post on this forum, after trying for months to get signed up. FWIW: won't work on Linux computers. I need to have the swing cylinders repacked on my 1966 580-CK. The hydraulic shop fellow recommended I just pull the rods and pistons rather than try to remove whole...
