Hi all. I recently picked up a 1981 Case 580D, so I'll probably be here on the forum quite a bit :notworthy It's my first real backhoe, (had a Ford 9N that I put a hoe and loader on), so I don't know much about them.
My first question is regarding the Swing Frame. All the arm bushings seem to be pretty tight, but I can feel the swing frame moving up and down underneath me as I work the hoe. There seem to be two large threaded adjusting "straps" or "hooks", sort of, (don't know what to call them), with 2 inch nylock nuts on them, and it looks as if tightening them will pull the swing frame tight to the tractor. I put a 3/4 inch drive 2 inch socket on them with a 4 ft cheater bar and nothing moved, even though one of the adjusting straps is slack enough to move by hand if I set the bucket just right. Are these things something a normal person should be able to tighten up? Do I need an 8 ft cheater bar? Or would it just be easier to try and cut the nut off and get a new one? :Banghead
