It's pretty straight forward. Not a complicated cylinder. Be careful taking it apart, there is a spring in it under load.
Are you sure your cylinder is rebuildable? The first generation cylinders were not as the end caps were crimped on.

The spring is what I'm a little concerned about.

 

The ideal situation is to get the cylinder to come apart from the rod end. Once the rod end cap is 1 turn loose push the rod against a solid surface and get the rod to retract about 3" or so. While holding it there carefully unscrew the rod cap all the way. Now cover your work with an old towel (will control spring) and gently and slowly allow the spring to push the rod out holding one hand on top of towel.

That is great advice. Thank you. Best way to loosen the cap without scarring the finish?

 

Don’t worry about it. Do what you need to do. It’s a old loader, right? What’s a small scar here and there. That’s all in jest; I don’t like scuffing stuff, either.

 

Exactly what I did. Wouldn't you know the bottom cap came of easily. Top cap won't budge. I'll get it off. Have a couple of days before my parts arrive.

You dont really need to get it off, replacing the rod packing is just as easy with it in the cylinder body.

Try warming up the cap with a hair dryer or heat gun. Some of the locktite that was used on the one I had creaped a little.

 

Everything came out the bottom end on this one.

 

Interesting top rod seal/packing on that cylinder. The top does have to come off for replacement.

Take off the brass fitting its just pipe thread. The rest will come out. Where was yours leaking? If you don't have to do not remove the plastic piston on the bottom of the rod. If you do make sure it gets in the same alignment as before. Mine would not fully return to the top because of that I think.

 

I see this post is a little over two years old but I am wondering if you have any information on where to buy the rebuild kit. I am working on the same cylinder for a friend of mine and I’m having trouble finding the kit. Any help you can provide would be greatly appreciated.

 

Steve Y should be able to fix you up.

 

Yup, that's where I got my new seals and they work perfectly.
