This is a long discontinued Jeep optional roof spare tire mount. Having trouble getting the hollow pin out of the center bolt.
Thought it was a roll pin, but I can't see a split in it, so it appears to be a tube.
Tried placing a hammer against it and tapping with a rubber hammer. Did not appear to move. Tried tapping with the flat side of a ball peen, still didn't appear to move. Used a bigger hammer, didn't move.
Not yet critical that I get it out, because the bolt is not freed up through its whole travel yet anyway. (Note, when installed the hub moves and the bolt is stationary. 1 1/16" head 5/8" diameter heavy bolt, steel)
I don't have a torch, was hoping for ways to get it or learning the correct method of knocking one of these pins out.
you could try pressing it out with a c-clamp. On one side place a large nut or socket between the stud and the c-clamp base with the pin in the center of the nut (have room to be pressed out) and the crank down on it. Would hit it with some solvent, PB Blaster or similar first....
Anyway, pressing it out will be better then pounding it out

I attempted that today, but didn't have the hub clear enough from it to get a nut down in there. And it had had a right good soaking in PB Blaster for over a week. Tried CRC Freze-Off too.
Bonus: Now the bolt is stuck right good in the hub anyway, either direction. Loaded up the cavity with PB Blaster and will let it sit until Sunday and see if I can make it move. Next attempt I think I will hit the hub (has the outer threads) with the HF $10 heat gun on high and see if that does anything besides blister the paint.
As for that pin, I might be better off grinding the ends down and if I can get that bolt out of the whole assembly replace it with stainless of the same thread. Only place I found a long enough stainless heavy bolt (1 1/16" head, 5/8" body diameter) is a marine supply place.
Going to guess the only reason that pin is there is for safety crap.
Try thin vice grips on both ends of the pin. Twist both vice grips back and forth in an attempt to break the pin loose enough to work out little by little. Work them like sticks in a skid steer. Another idea is to find some thick rubber hose and cut a section out of it. Slice it up the middle and slip it over the shaft. Stick it in a vice and try to hammer the pin out with a punch and hammer. Might work, might not.
Maybe I don't understand what this thing looks like, I've never seen it before, but if the objective is to get the bolt out, can't you just cut off the part with the pin in it with a cutoff wheel or a hack saw?

Well, here is the problem with that stated in post #3. The bolt is currently stuck in the hub too, the pin is not yet the obstacle. The other issue with cutting the bolt off is that would destroy the bolt when I might actually reuse it rather than replacing it.
But if I can't get the pin out, I can cut the ends of it off and it won't stop the bolt from coming out if I manage to get it to thread out of the hub.
hmmm...take a pair of vice grips and squash the pin on one side and twist it out. Being a hollow pin, it should twist and shrink in diameter to pull it out. Or you could cut it flush and the drill it out. Either way it would be gone.
also, it looks like there may be a lock nut in the hub...
What about an angle grinder to grind down the pin. Then at least that part is taken care of. Being careful not to mess up the threads of the large bolt so it can twist out (if thats its method of removal)

1) Where did you find that diagram? It looks like what passed for instructions that came in the box.
2) I don't think there is a lock nut inside the hub, I ran the bolt in and out a couple of inches each way before getting it stuck where it is now (hollow pin barely clearing the hub face). That nut and washer at the bottom of the upper "3" group is a regular nut and washer that you tighten down to adjust the bolt height or just to tighten the bolt. It is outside the hub.
As for that hub, it seems like there is a welded in nut at the top, but not sure of the lower shaft is threaded or just a hollow smooth tube.

Yes, that and maybe drill the pin out or even grind it flush with the flats already in the bolt and insert a smaller roll pin if I even keep the same bolt.
Cool! I thought I looked all over for old instructions etc. online and didn't find anything close.
New plan of attack. After bolt soaks a few more days try to see if I can move it with 25" breaker bar again, add heat yo hub with heat gun. If it moves okay, get out or grind off the pin and unscrew bolt all the way.
If I can't get the bolt to move enough to come out, rent a 1/2" impact from Sun Coast and see if I can get the bolt out. Clean everything up, paint, use a marine stainless bolt, nut, and Nord Lock washer set.

That is the best idea yet. I would grind down the pin until close to the threads, then drill the pin out. It is probably just rusted in place after years and years and won't budge.
The soup thickens.
I am going to get that pin out by any means necessary. Then give the bolt tug with the 25" breaker bar one more shot. Might even put the spud wrench on there with a 48" piece of pipe and see if that frees anything back up.
If none of that works, and I doubt that it will, I shall try an impact wrench.
Thought it would be a great idea to just rent one from Sunbelt. In theory, that is awesome at $20/day online price, plus tax etc. Well, to rent a $200 corded 1/2" drive DeWalt impact from them, for $20/day, the grand total is over $700, because the closest store of theirs that has one is 80 miles away.
United Rentals has one with a 3/8" drive that doesn't seem to have a great torque rating, $31. A guy local on Facebook is selling a Craftsman 19.2v 1/2" impact with charger, one good battery, one weak $55. Looks like those have a max tq of 300 ft/lbs
I got one last black Friday to use when I do my leaf springs. It is very powerful, but it continues to spin after you release the trigger. There's a name for that but I can't think of it.
