Glad to see you are getting the repair underway. Actually if all is right in your hydraulic system there will be little to no air in the hydraulic system. So the statement about the cylinder ending up on the other side of the barn is only adding a colorful ..what if.. to your story. When you operated the lever to push the piston out of the cylinder once the seal between the cylinder tube and it were broken the piston and ram would simply fall away under gravity. Liquid does not compress that is why pressure vessels and piping are hydro tested, so if there is a weak area that fails the release energy is very minimal at the point of failure. For a hydro test the internal volume is filled with a fluid test media which is quite often water, bleeding out all air or at least every bit within reason. Then applying pressure to a predetermined test pressure. I would guess quite a few have seen pictures of an air tank that has failed and quite often it shows a large ripped out area. That is due to the stored energy the compressed air contains. A failed area during a hydro test will be a small non deformed hole, crack or gap. Once the pressure that is slightly deforming or stretching the item under test is released nothing else happen except the test media slowly drips or trickles out of the failure point. Understanding there may be air in the system the precautionary measures of the constraint of the strap was a good idea. I am also in no way singleing out George or his methods just additional information from my experience.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
