Been soaking it with Kroil for about a week and no luck. This pin won't budge for me to get the arm off the tractor. Any tricks of the trade to get it out? Not sure if heating up the cast hangar is an option. Just worried it might crack after getting it hot and a few whacks with an 8# hammer. Was also thinking about taking the entire hangar and arm off to try to press it out on a press but that might be worse than heating it. I also tried turning it with a punch in the key hole just to move it but ended up only bending the punch! Any ideas or tricks? Or just keep soaking and whacking it? Thanks!
