Had the stabilizer control valve blow a spool almost completely out, far enough that it was raining oil at the back of the machine, I managed to get the stabilizer leg up far enough to get out of where we were working and to a spot to work on it. I decided to replace rather than repair the valve, I reasoned that even repaired the main components were still over 30 years old, I located a new one for an outstanding price from FP Smith https://www.fpsmitheq.com/. The orbital hydraulic steering valve has been leaking as long as we have had the machine and it would if you ran the machine long enough it would fill the steering column with oil and it would in turn leak out on to your lap.I located and bought a new steering valve with a new steering column from https://www.flinthyd.com/ for half the price Case or just about anyone else wanted new and the same as a used one. The brakes had a problem since we owned the 580, someone had put brake fluid in the system instead of TCH or Dexron ATF, needless to say it killed the rubber parts. To fix the brakes I bought a pair of Hyster fork truck master cylinders off of Ebay as well as a pair of new brake slave cylinders from https://www.reliableaftermarketpartsinc.com, the brakes will now use brake fluid and the parts cost less than one new original Case master cylinder. The parking brake has been non operational as long as we’ve had it, I freed the lever assembly and bought a new top quality U.S. made cable from https://www.terraparts.com/ for about half of what a new one from Case would cost.
All together with 5 new hoses for the steering valve the price of all the new parts with shipping was about $1350, not bad at all.
