    Two different size cylinders on Case model 35 hoe... what should I do?

    Howdy. The saga with my worn-out hoe continues. I'm still trying to figure out why my hoe functions don't work. I have all the O-rings to rebuild the valve bank and hopefully tomorrow (Saturday 11/11) that's what I'll be able to do. I've been noticing that my boom cylinders are all oily...

    Case relief valve disassembly....how is it done?

    I have 8 of these to disassemble but I'm not sure exactly how it's done. I can't get the snap-ring out because the nut is in the way, and the nut won't budge. I figured while I was disassembling the entire valve I might as well replace those O-rings in these valves...if I can get them apart...

    Case 580B CK backhoe valve block seal availability

    After sitting for about 5 years due to removed and rebuilt swing cylinders that I just got back in place, I started up the old girl. After the starter got tapped into submission, she started right up! I was surprised and impressed. Well, none of the hydraulics worked and the pump was whining...

    Questions about old John Deere 350B crawler/loader

    Good day! It doesn't seem like this forum is too active anymore and I'm not sure if this is exactly the right place to post, but I'm giving it a shot anyway. Almost 10 years ago I bought a JD350B crawler/loader with a backhoe attachment. This was the first piece of heavy equipment I had ever...

    Case 580CKB starter electrical problem...should be easy, but I'm dumb!

    Good day. I turn the key, the solenoid goes click but the starter doesn't turn. I remove the starter and test, the motor turns. I reinstall the starter, same thing...click, but now go. Fully charged battery, clean battery posts and new cable terminals. Only thing I can think of is that...

    Case 580B welded in bushings?

    It appears that one of the previous owners of my 580B decided it was prudent to weld in the bushings in the dipper of the dipper to bucket connection. Anybody ever had to remove one that's been welded in? Suggestions would be appreciated. Thanks Glen

    Case 580B Cessna backhoe valve

    Seems like every time I use the machine I find more leaks. This time there is a relief valve that is leaking. This particular valve says "CASE" and Cessna on it, but it is not like the one shown in the parts book. There is a CASE part number on it and a serial number. Can anybody point me in...

    I've been reading and searching on the forum for sources. I can't seem to find exactly what I need. I have found the standard parts sites: hwpartstore, epsstore, broken tractor, heavy equip. Then OEM places like Coleman Equipment. I haven't called any concerning the Bushings and pins I need...

    Case 580 CK Series B now moves!

    I have been reading the threads on this site about the issues with the Shuttle-shift in these tractors. Mine exhibited the classic symptoms... Won't move in forward or reverse or moves sluggishly and has no power. I figured I was in for a tractor split to replace the clutches on the shuttle...

    Stuck hydraulic filter housing on Case 580 CK B

    When I got the machine (6700+ hours) the hex on the bottom of the hydraulic filter housing was toast. I tried using a strap wrench, but no go. Anybody have a trick or tip to getting it out? Prefer not to use heat since the housing appears to be aluminum AND all I have is a small propane...

    Good day y'all. I've been having a terrible time finding cylinder rebuild parts for the dipper cylinder on my Case 580 CK B. It's a 4" piston, 2" rod. They come with 2-piece pistons and 1-piece pistons. My parts manual doesn't show the 1-piece design. I've pulled the cylinder apart and...
