Pin stuck in spherical bearing ?

How do I remove them. I beat the heck out of it with a hammer...I can't get tension on it to pull on it and beat like the other? Would a air hammer help?

Air hammer should help. If pin is junk possible to cut it out from the inside with a torch. Blow hole in middle and it should shrink some when cooling

Heat, oil, and impact. Various combinations of these three until it moves.

 You need to figure out some way of keeping tension on the pin while hammering.

If seriously stuck, bitty has nailed it already. can't be stuck if it is liquid.

The air hammer is the second best magical tool on rust.

If the rust dust flies when hammering, keep doing it.

It is working the rust loose and it then falls out.

If no dust, you then need to go to the Big Dog, The Gas Axe and make it liquid.

Rust Jacking is similar to pipes freezing.

I'm confused.

You have a pin stuck in a 3 point lift arm or top link?

It's in my trailer tail... I need to remove and repack the lift cylinders. The picture was to make sure I was calling it the right thing.

I'm sure really tough to access but backing up the opposite side with something solid should help the forces transfer to the pin instead of being absorbed by the assembly, an eager assistant required and constant pressure applied with an air hammer

For $65 you can’t spend much time urinating around trying to save the old parts.
