I am curious if you know if it was originally installed from the inside out or the outside in. At any rate, it is a very tight fit, and I can't imagine how it migrated into the stove unless it was only partially threaded or perhaps different expansion rates of the cast iron and the steel (?) bushing, combined with the vibration and motion of the rod going in and out.
Taking the sides out helped me become much more familiar with my stove, and allowed me much better access for vacuuming out the side chambers. Thank you again for helping me through the disassembly.
My bushing was installed from the outside and kept working loose until I cranked it into place. It took a little rotational tapping with a small screwdriver and hammer because I set it into the tapered thread in the hole with the rod in place while the stove was hot. It hasn't moved since
Glad to be of some help.
