Lucille,
I will repeat what I mentioned earlier, I think you will be in serious danger if you attempt to shove the pin out with a press. Any load bearing will be between those two cast iron pin bosses, and we all know how brittle cast iron is. You have absolutely no feed back with a jack handle or pump handle so you don't know how hard you're pushing.
If you can pinpoint your heating efforts on the cast bosses, they will expand. It must be done quickly so the pin doesn't grow with them. You have to get real serious with your hammer.
The picture you linked shows no evidence of blistered or blackened paint...you need to put some serious heat on this thing.
Some type of shouldered rod should be stuck inside the pin so you have an extended target for your big, heavy hammer blows.
The assembly needs to be supported so it does not move at all. Any cushioning effects will deaden the sharp blow of the hammer.
Once you break the pin loose, you have it made. It has to be done with conviction as the pin is thinking "you aren't going to move me"!
End of rant!
Stuart
