Removing the pins that connect the front axle onto the radius arms on the 8N seems to be a common problem, and like others I've tried everything to shift them. Making it worse is that someone had tried to remove the pins in the past, and one end now looks like a round rivet head. A cutting wheel was used to remove the 'rivet' end, but every attempt to remove the pins has failed so far. The casting and radius arms are off the tractor and on the bench, and I have an oxy acetylene kit from my A/C days, but have no idea of how to use it to free the pin. Do I heat the pin, or the casting and how hot?

Are you trying to remove the pins from the arms or the axle? How did the arms come off with the
pins still in? Why can't they be drilled out? A picture sure would help.

As you've probably discovered, may have been easier with the axle still on the tractor. Gives for more holding everything solid better. Maybe not a lot easier, but a little
In general, you heat the part that is holding the other part, as heat expands. You don't want to expand the pin. You would get it good and hot, probably almost red.
The challenge comes when the part holding is a heavy piece, and the part that is held is lighter. By the time you get the outer part hot enough, the heat has transferred to the lighter part, expanding all.
I have used my torch more times than i could possibly count to loosen up stuff. But using a torch, and not getting the part loose, then cooling, can sometimes make it even harder to separate. Sometimes, drilling, dissecting, etc is the only way.
Since your axle is off the tractor, the axle is heavy enough that a strong shop press would probably do it. If you do get to a press, Be Careful!
I tried drilling a 5mm deep hole with a 5mm diameter drill so that the air hammer wouldn't drift off center, but either my drill bits aren't up to the job (Harbor Freight) or it's a really tough steel.(quoted from post at 05:59:07 03/26/23)As you've probably discovered, may have been easier with the axle still on the tractor.

Maybe try again after I get the pin toasty :lol:
