The pins are supposed to move within the hinge strap, not the hinge body. Usually they seize in the strap and end up turning in the frame instead. If they are seized in the strap use a cutoff wheel or other tool to cut the pins between the strap and the frame/body. Then using heat, drive the pin from the strap. Fabricate the bottom and top pin mounts out of bar stock and replace the old ones. The new mounts should be drilled to fit the new pin and the knurled portion on top should secure it at the top. If the strap holes are worn, you will need to drill them out for the next size pin. The kits that are supplied are usually a way oversize and the bushing are not useful for this application.
I was lucky to have Ray do my hinges and he did a really nice job. I don't think that he does them too much anymore but I could be wrong. | | |
