Heat the pin? Won't that just make it tighter?

(Sorry if I'm being ignorant).


Not ignorant at all. Heat actually expands metal, but with such a big heat
sink as the casting is, heating the pin is likely to break the rust bonds
inside and free it up, with less effort/heating time. Heating the casting
would be the right thing to do in order to swell it, but most times just
breaking the rust bond is all you need to do.
