I am lucky that there is a hydraulic engineering shop a couple of miles away and with some of the bigger modern cylinders I just take it to them and pay $25. They have a humongous hydraulic press, big Lead blocks and all the special jigs and hydraulic wrenches. I can walk in with my own seals and fit them right there.
Absolutely spoiled.

The tricky part often is putting the new seal in the plug end.
