Default Hydraulic Cylinder Bore and Stroke

Hydraulic Cylinder
Can someone tell me what size this is
I have measured the shaft at 5/8" and it only comes out 2"
So would that be 5/8 bore 2" stroke
A new one this page says its 1" bore and 1-1/2 stoke

https://www.constructionparts.com/b02-03-0010.html

The one I have leaks down as soon as you let off the switch.
The rebuild kit for this one is 170.00
I may just take it to a local rebuilder

The bore is the inside of the cylinder not the rod size. Pull the gland nut off to measure.
Best bet is to pull it apart, clean it up, and take all the clean parts and old seals down to Martin Fluid power on 38 st and Broadway. Go around back. They can fix you up with all new parts, you'll probably be into it for 30 bucks or so.

Well Martin Fluid could not find any seals for the cylinder.
They sent me to Arizona Jack Repair. He said call a place in Florida.
I called the manufacture and the seal kit is no long available.
Next week I am going to try one more local hydraulic repair company.
I have tried to just find a new cylinder on the web and no luck.
It has a one inch bore and a 1-1/2" stroke.
All I can find has a much bigger stroke

Have you taken it apart yet? That cylinder is small enough, but could come apart hard enough, that to rebuild it still will take a couple of hours for a shop tesr it down, measured up the seals, clean and polish everything, and put it back together, and my shop charges $90 an hour, so a rebuild can get pricy quick. But, then we warranty our work for a year, so we make sure everything is good, and will make any parts needed to make it better than new.

For what it worth, we buy most of our seals from a company called Hercules Seal Products http://herculesus.com/.

Can you post a picture of the cylinder and the seals--if you've taken it apart, that is. We can get an idea of what the seals and the cylinder look like.

There's a good chance that you could simply replace the entire cylinder. A small one like that shouldn't cost that much to replace unless it's pretty specialized. I'm also surprised that you can't find seals, there should be something around and Hercules is as good as it gets for replacement parts...

For that price I would look at cutting one like this down.

They really get the price up for these small cylinders.

I finally found my camera. Here are the pictures.
There only 3 seals in this cylinder.
The whiteish looking one is shot.
The other 2 look good but I am clueless.
The shaft looks good no scratches
