Replace seals on NH7308 bucket cylinder

Does anyone know how to get the bucket cylinder on a NH 7308 loader apart to replace the seals? I've got the kit and an exploded diagram, but apparently NH doesn't have a service manual for the 7308. The outer nut on the cylinder doesn't screw into the casing, it screws onto the "cylinder head" inside. I can't figure out how to hold the cylinder head in order to remove the nut (which conceals a snap ring). Please reply short (I haven't paid the money to read "long messages", or reply directly to me at choltz_at_orbitworld.net. Thanks

Is the ring in front of the wiper seal? I see something there, but it looks like cast iron and I assumed it was the top of the cylinder head that the big nut screwed onto. The wiper seal seems to go in behind it. I took a photo, but at the moment I don't have anywhere to post it. ....

Never had occasion to take one apart but I'll take a shot. By cylinder head I wonder if you're referring to what my diagrams call the shaft-guide? It is a slug that threads into the cylinder body that the shaft runs through.

I imagine a part like a shaft-guide would have a retaining ring as Oneace says. Look for two metal 'ears' with holes in them that lay flat on the guide around the outside. You'd need retaining ring pliers. Also look for two shallow holes 180-degrees apart. If present, there are special wrenches for such things. ....
