Classic/Antique Car Repair: door hinge pin removal 1951 chevy p/u, door hinge, air hammer

Question
Hi, I am trying to remove & replace the hinge pins and bushings on my 51 chevy truck.I have soaked with liquid wrench used a hammer and punch and heated with a torch and moved the pin about 3/8". Alot of pounding for little movement. I didn't heat till red but it was hot.They have been in for 50+ years. Do you know any tricks? Air hammer and heat maybe? Any help would be greatly appreciated. Thanks, Ron

Answer
The problem with all the pounding is that you have managed to expand the pin so that it makes it even harder to get our. Doing a restoration so as not to harm the hinge itself when I find this condition I take the hinge right off the vehicle. I mount it up in my drill press so that I can drill a straight hole through the center of the pin about half the diameter of the pin to release the pressure. In a lot of cases then some heat and using a brass drift punch usually moves the pins. In the future look in a magazine like Hemmings get a door hinge pin remover. It is a small portable press. Good Luck.
