Henry Mark IV backhoe swing motor

[treefarmer88]

Hi guys,

Just bought a Henry Mark IV backhoe for scrap price. Hooked it up to my case 530 and all is well other than the swing motor leaking on the top. Before I crack this open, can anybody give an idea of what I'll find inside? O ring? I think it's a Cessna motor from what I've read. Thanks!

Its been a while since these posts but ...if this helps anybody...
I have a '79 MF50C loader/backhoe with a 54A backhoe. I just had the swing cylindar repacked and it cost me $733 for the seal kit (AGCO part # 837180M92 ) from Lindstrom Equipment online because the hydraulic shop couldnt find the parts either. It also cost me $800 for 8 hrs labor.
So yeah... $1533 to fix the swing cylindar. I took it out myself which was a bit of a pain and I still need to reinstall come a little warmer weather. The cylinder was just to heavy for me to handle easily and the shop could do a pressure check to make sure it was holding pressures properly so I had them do it. But im determined to get this 50C up to snuff.

The swing cylinder for the 54A backhoe is also a Cessna. Ive attached a parts list and blow out diagram of mine if this helps you at all.

On YouTube there is a channel called watchweswork and several years ago he did a leaker, and it seems to work ok.
