I need the seals and back-up rings for the Cessna Rotary Cylinder. Do you have those seals either individually or in a kit?
JAW710 gave you a link to the seal kits this site's owner (PartsASAP) shows online. JAW710 didn't say he has the seals, and the PartsASAP parts sales department doesn't monitor these forums and answer questions like you asked here. You will have to contact PartsASAP.
From what is shown on the pages related to that link, my guess is PartsASAP won't have anything like the parts you need for a Cessna rotary swing cylinder listed and I doubt a call to them will yield parts for one either, but it's worth a try.
Some people/places won't even know what a backhoe rotary swing cylinder is, a clue to how popular they were/are. This is going to be a call or visit search, not just look at website parts lists. You can try calling a place like Baum Hydraulics (they have a website where you can get the phone number), they do a lot with cylinders, seals, seal kits, and other hydraulics. They might have some info on those cylinders. Other members that have or had these cylinders may see this thread and toss out some other places you could
call. Have you talked to a full-service hydraulic shop that actually rebuilds pumps and cylinders? Have you located a Cessna Dealer and talked with them? Cessna Hydraulics is an Eaton brand now, if you haven't found that, so an Eaton dealer might be able to get you info.
There have been some threads on various forums, here and on other websites, about rebuilding some of those rotary cylinders. They were not the greatest thing going once they got some age on them, and a number of people modified their hoes by removing the rotary cylinders to use common rod type cylinders or cylinders and chain systems on the swing. If AGCO has the parts available that may be the best source for them, even if it is harder on your wallet than you like.
Good luck, you are looking for something that is not popular enough to have much of a part offering in the aftermarket. There may be some cross reference materials somewhere (like Baum), but I can't tell you where to find any for certain. MF, Allis Chalmers, and John Deere where some brands that had hoes which used rotary swing cylinders for a time. A major search for parts appears to be a common theme with all of them people are trying to repair. A search of the forum archives here may turn up some old threads related to the rotary swing cylinders.
You might start a thread about this on the Massey Ferguson forum here asking people to look at this thread if they have any info to help you.
