I finally got to disassembling the cylinder. I got the gland nut wrench as you guys recommended, works great, and removed the retainer ring inside. Now I can not remove the gland nut. Any tricks to use to remove it, or do I just use a brute force? I do not want to mess up the piston.

at work we have air cylinders that have the side grove in cylinder.
were you able to spin the the end of the cylinder?
If so spin it again slowly and look in the slot on side of cylinder there might be a wire type lock ring in there.
Spin it slowly and look for a gap in ring if you find it then pry out one end of wire out gently and spin rod end of cylinder and it might spiral out, some times you might have to pull on wire with a pair of vice grips as you are spinning it.

The cylinder end would not spin but I can spin the gland nut. The nut moved out a little just so the ring groove in the slit disapeared towards the end but I can not grasp the nut, it is not out enough. The nut seems to be made out of aluminum or something soft, it gets scored easy when I try to grasp it with wide pliers. The gland nut has no handle to grab so I do not know if I can just pull the rod out with force (what force). I will see if there is a groove inside the cylinder end.

IDAHO:
You have one kind of cylinder I have not taken apart, tho I have
seen them on an SMC loader. Post another photo when you get it
out.
When you do, your piston nut will be torqued on with about a
million ft-lbs. I have found the best way to get them off (if you
do not have a 3/4-drive impact tool) is putting a rod thru the
other end and parking a heavy vehicle on it. Then use a socket
wrench with cheater bar.
The other glands I have removed use:
> tie rods (as shown by Ted)
> face-hole gland nuts, as mentioned
> circumferential-hole gland nuts, on some after-mkt cyls I got from
Surplus Center
> inside snap rings (JD loader)

OK, guys, I got the cylinder apart. There was nothing special about it. I went to a pro shop and asked. They told me to knock it out using a hammer. So I did and the piston pulled the top out. I undone the piston nut and removed all the seals. There are eight of them on the piston and the gland nut. Now I do not know how to order the new seals. There is a rebuild kit mentioned in the Bradco manual but I can not find even the model on the net. So I am looking through the H/D catalog and can not make sense of it. I am not sure how to measure the seals and O-rings when the are worn out or damaged while removing. I guess I need a lot of help.
Help, help, help!
