Help getting ram off of pacific multipower

[Griz44mag]

As stated in the title,

I received an old Pacific multipower press from an estate sale and want to replace the damaged ram.
I have a replacement ram for it, I just can't figure out how the bottom (pin or bolt?) is removed.
One side of the thing looks like it may be the end of a pin or bolt, the other side is slightly larger, but flat.
It almost looks like it was sheared off, but since I did not do it, I am not so sure.
Can someone tell me what the thing is?
Is it a bolt or is it a pin? I tapped on it with a punch, it did not move.
Before I get radical and drill it for an easy-out, I thought I would ask.
I can't find a manual or exploded breakdown for it.
If someone can furnish information or a source for the breakdown information, it would be greatly appreciated.

It should be a pin. That's what most presses use.

I have two old Pacific C presses that use pins, but they're a little different in that they use cotter keys.
Then I have a much newer Pacific, SuperMag which uses a straight pin.
I think that's all of my Pacifics?

You probably need to soak your pivot points in Kroil, ATF, or some penetrate for a few days, turning the press over in various positions throughout the day, adding more penetrant.

Then get the press on a solid foundation, a good punch, a 3 or 4 lb sledge, and let loose!
Be careful that the whole frame is supported, otherwise you can crack it or plain bust it up.
Think, frame block when driving pins out of 1911 frame.

Oh yeah, throughout the day, when you rotate the press, lightly but firmly tap on the fame pivot point with a light hammer. Preferably nylon or brass. Then add more penetrant.

Mine has a drift pin that must come out right to left as you face the press. A good block under the press and a stiff swat with a hammer and punch will break them free. Once again I emphasize a good block for support. Otherwise the cast iron WILL break.
