What is it?

Its on a Dig-it 188T backhoe..the numbers on the other cylinder is 62887 best I can tell..I thought if I could get it apart their might be numbers inside.

Looking at the last pic it almost looks like its got a 1/4" dimple or hole in the end cap. If that is indeed a dimple there should maybe be another then you'd have to have a wrench that has pins sticking out. Then the end cap should just thread off. If you don't have a special wrench you could use a drift punch and tap it with a hammer to try and get the end cap to thread off.

There's a wire in that groove.  From the picture it looks like it on the close side.  Put a small screw driver under the end of it and a spanner wrench in the 2 holes on the end cap and turn it clockwise.  As it turns the end will come up and out.  Kind of like peeling an apple.  Once its out you should be able to pull the rod and cap out of the cylinder.  Might have to secure the cylinder to something and put a bar in the end of the rod to help pull to remove it.  There might be numbers on the packings inside, but any good hydraulic shop should be able to match them up if they can see them.  Hope this helps.                     Stewart

Yes it has 2 holes in the counter sunk end cap.

I guess more cleaning is needed to see the wire.

I'd have to agree with Dieselnut.

 

From the looks of it I'd say it has a flexible spiral key that fits in a groove around the endcap. There should be a matching groove around the end of the cylinder. The key fits between them

 

I  used to see that set up on  hydraulic actuators for Mcevoy API Gate valves

 

We used to have to grab the end of the key with vise grips, and tap the vice grips with a hammer to get them out.

 

That one looks pretty rusty, so it will probably take some work to get it out.

It looks like its there.  Probably does have some rust in it and most likely dirt too.           Stewart

I really used to hate those things. That one should be pretty short. I was repairing cylinders with a 16" bore, the spiral key was a couple of feet long.
