CA Rear Rim Change

Just wanted to ask some advice before I move forward. The rear rims have been rotten on my CA for years, but I kept using it until they finally collapsed a couple weeks ago.

I have new power adjust rims for it but need to get these apart. I got everything lose, except the locks. I currently have them soaked in Shop Stufff (a canola based penetrating lubricant), and Krown penetrating oil. I don't have the tool for them and as you can see, one of the square nubs was already broke off when I got the tractor. Sorry, I don't know all the correct terminology for each of these parts, so bear with me. So what would be my next move? Should I apply heat? And if so, where?

Lay the wheel on the ground, on a clean sheet of plywoor, or tarp (easy to find the parts, thataway, especially the rail followers). Then give the center a couple taps between the clamps, all should fall away fairly easily.  If not put some more penetrant in th clamp, and hit it again, later.

You may want to put a socket over them, hammer on the socket.  Doesn't matter what size or square or hex, as long as it protects the head from mushrooming.  Hammer from front and back, alternating, add penetrating oil as needed. sometimes it takes an hour per clamp, sometimes more, to get them moving.  Once you get the front-back movement, then try twisting. When you get the front-back movement, then you can pull the snap ring off the back, allowing more penetrant in...

I have some spare eccentric's if you need one.

You can see where I got the wedges moving, by the break in the paint, but that's as far as I got. So is everything pretty tough? Can I just put a wood block on the center and pound on it? I did read that trick on this forum about putting them in the woodstove overnight. That one that is broke off, can they still be bought new?

Thanks a lot everyone! I'm just letting everything soak for a day or two.

That was my biggest fear was that those centers were going to be rotten but all good!

Cut the rails out before you scrap the rims...

So next dumb question. Will it be easier to assemble the hub  back into the new rims and 

Once you have the eccentrics apart, cleaned and in working order, unlock the eccentric. If possible have a helper hold the wheel center and start loosely assembling the clamps in place in the rails. Once all 4 are loosely bolted In place, start tightening them evenly all the way around. They will become tighter on the rails. It will require the power of the tractor to slide them on the rails at this point. Once you have them where you want them, turn the eccentric to the right-until it hits the stop. Once all 4 are locked down the wheel will be locked in place. Make sure you put a locking collar on each side of a clamp to make sure it doesn’t slip.
