Those track presses are nice on bigger machines. On D-6 and smaller the sledge hammer and pin work just fine as it takes a little time to rig the press up. I have maxed out the 150 ton cylinder pressing a 245B track apart and had to help it with heat and a sledge. Fun Fun!
Here's a picture from ACMOC of one tool. Cutting into each end is by far the easiest way, especially if it doesn't move after several tries and the master pin starts to swell. Using two torches, one on each link, is better also. Phil
Yair...we used a jelly gun. this was a piece ten inch square solid steel about three feet long with a hole up the guts to take a piece of inch and a half shaft. There was a small hole drilled through the side through which you could feed an electric det and start off with about two inches off a standard plug of gelignite. Worked like a charm on Nine G pins provided you had everything lined up propper. Also worked well on ducks if loaded with ball bearings.

I love it! On a smaller machine it would punch out the pin,and dismount the track in one big bang. Sounds like a real labor saver!
