Welded cylinder repair

rrlund · Jul 31, 2016

On one of those welded hydraulic cylinders on the combine header lift,how do you get the snap ring off so you can pull the ram out and put a kit in them?
I had one start leaking like a sieve. I went to the salvage Friday and got another cylinder,so it isn't a major issue,but now I have that leaky one laying here.
I can see the snap ring down through the threaded hose hole,but it's only a 3/8ths hose and I can only see one end of the snap ring at a time. The gap is so wide I have to turn it a little to see the other end. It must take a special pair of snap ring pliers to get it off. I sure don't have anything here that would do it.

Take a screw driver or other tool in the hole and move the snap ring to another groove on the rod. It will then let you remove the rod.

OK,that was simple enough. I laid it on the bench,popped the ring off and it slid right apart,but now it begs the question,how do you get the snap ring back on?

Reverse the process. There should be a lower groove where you rolled the snap ring into. Then you just roll the snap ring back up into the upper groove.

There's about three inches of tube below the hole and the ring is down in there. If I stand it on end,it's so heavy it'll drop the ram all the way to the bottom of the tube on the snap ring. Maybe I could hang it up on the cherry picker and try to fish it down to the hole with a magnet and get it sitting on the end of it.
I don't know. Maybe I'll get a kit for it one of these days and try it so I have a spare around here.

I don't understand, or else you don't! The snap ring always stays on the rod, not loose in the cylinder. The kit usually includes the wiper, seal, and snap ring. The snap ring is placed in the lower groove, before placing the rod in the cylinder. Then you work the snap ring back up into the higher, narrow groove, with a screw driver, working through the port.

OK,I see what I did wrong now. I popped it off toward the back end of the rod. The other grove is toward the front. I went out and dropped the tube on a wood block and knocked the snap ring out of it. I worked it back on and in to the beveled groove ahead of the groove where it locks in.

Simple process when you know how it works ain't it?

R tried to e mail you but no luck. When you come to Tennessee I have a genuine OLIVER remote and an intake for a oliver 66 that I had ported for a pulling tractor. Both yours any time you want to pick them up.

I sent you an email Jerry. Let me know if you get it.
