WD45 spinout bolts stuck

The four locking bolts on the rim are stuck. Tried heating up the bolt with the torch and melting wax into it, twice. Then heated the block piece and not the bolt. PB blaster over several days. Still have the tubes in them so they can't get too hot.

1200 ft # impact gun didn't budge any of them. Used a 5 foot bar and a long breaker bar and it broke the piece that holds the socket (1/2 drive).

Not sure what else I can do without destroying something.

I removed the bolts that go through four locking pieces and the large center section (piece that bolts to the tractors hub), should the center just fall out now or is something holding it in?
 
The wheel rim locks are a four piece lock.
There is the main body, the eccentric pin
and snap ring, and the block or wedge. The
block just lays on the eccentric pin. The
pin is held in the block by a snap ring. I
had a couple that I had to stick the block
in a vise and heat it to free up the e/pin.

Lay the whole assembly down. Then with a large sledge hammer you can drive the wheel down out of the clamps- which will be left hanging on the rails. With the pressure off the clamps now you can work on them freely.
 
So this section should just pound out from the other side since I removed the 8 bolts?

Hubs pushed out with a few swings of the sledge and an oak block.

The locks took quite a bit to free up. I sand blasted them first, heated each one til nearly the whole thing was glowing. Took half a candle for the four of them and going from forward to reverse with the impact gun. Seems they loosen up the most when cooling down, maybe 300-400 degrees. Even with the supposedly most powerful 1/2 gun on the market it still took a couple of minutes.
