Case 580ck loader and backhoe hydraulic cylinders seal repair - what size big sockets needed?

I am about to embark on replacing seals on most of the hydraulic cylinders on my old 580CK. I need to buy a big-socket-set, but don't know (even after looking at the manuals) what size the nuts on the cylinders are. Figure buy a set of big sockets now that will do them all. I know the swings are 1-7/8. Anyone know what the other cylinders on the loader and backhoe would typically be??? Should I get 3/4" drive or 1" drive sockets? I know I'll need to use a long cheater bar to break them...
