Thanks for all the replies. Been out of the country and out of the office...but not in a good way!
After removing the cylinder and getting a good eyeball on it, I could see that it was slightly bent.
Took it to two different hydra shops and both said it couldn't be rebuilt.
Called up my Deere shop and got a new one for $550. For that price it's going to have a seat at Thanksgiving dinner each year. Yikes.
Seems like it's just a simple cylinder and someone could make one, but neither shop could.
Live and learn.
