I am in the process of repairing the hinges on my 37 IH. The original pins were about .290" diameter and 2.75" long. I am having trouble finding new hinge pins and am not sure what to do. I canlt really go with origianals becasue the hinge holes are worn slightly. I could make the hole oversize and add some bronze bushings, but I would need to press in the bushings and then bore them out to fit a new hinge pin. It would also take 4 bushings per hinge. I was just wondering if someone had a better idea. The way I am looking at doing it seems like a lot of messing around. Thank you for your advice.
Make you own? A hand drill clamped in a vise (or a drill press) with a piece of round stock chucked in it, file & hacksaw.
Could you drill out the worn hinges to match a more common size pin and skip the bronze bushing step?
i'd take a look at `35-`48 ford hinge pins , they are .28 in diameter...you could install some bushings and then ream your hinges out to fit. the pins are about 2.75" long , available in plain steel or stainless steel oversize hinges pins are also available...i believe they are about .34 diameter. you could then ream your hinges to fit and not use any bushings
Thanks for the replys guys. I wasn't sure if the oversized would be too big or not. I would have to ream almost .050". I would think it should still be strong enough but I'm not sure.
I would just go to either an auto parts store and buy a hinge repair kit that is larger, and just redrill your wobbly hole out round. The outside of the hinge doesn't need the bushing's, because that's what hold's your pin from turning and falling out. Also a good hardware store will have all sort's of things to use as far as pin's and bushing's. Another ideal is to just weld up your holes and go back to stock size after drilling them back out.
on a `40 ford convertible i did , i made my own oversize hinge pins out of 5/16 stainless steel bolts. FYI 5/16" is .312 i reamed the hinges to 5/16 , and then i rounded over the hex heads in my lathe and then polished them. to give them a press fit into the body of the hinges i gave them a slight knurl with a punch under the head so they would stay in i had pictures , but i lost most of them last week when my computer crashed
You may want to take a look at what I did on my Model A. It is probably more work than you want to do. http://www.jalopyjournal.com/forum/showthread.php?t=423508
welding up holes and re-drilling works great. using a 2 part epoxy might surprise you with the results. find a piece of round stock close to what you need and cut to length. to keep them in place single drop of loctite works great. oversize drilling is easier and less trouble. you can get drill bits with pilot end that work great. those bits are the ones used to fix throttle shaft bores on carbs.
Mid-70's Plymouth Voyager cargo door uses .266" x 2.75" pins. I just bought a set of 4 on Ebay for $8 + shipping. Happens also to be the right size for your '38 Chrysler if you've got one...
