Ive heard about all the fun people have with those frozen pins, I got one of em harbor freight presses and I reckon with a lil bit of heat I can knock ‘em out. Thankyou for the part number that’s the main thing I was looking for.irontwist wrote: ↑Thu Feb 03, 2022 2:41 pm675-5143 is the Napa part number. I tried to install them using the You-tube video with no success, pin would not come out. Heating and then using a press might be helpful. The end of the hinge is mortised with drill press before installing pin to accommodate the bushing which was countersunk according to video as i remember, which seems correct.
The poster of that video is a member of this forum, swptln. He still has a YouTube channel.64D100Poly wrote: ↑Thu Feb 03, 2022 12:52 pmI remember for a while there was a good video on YouTube of someone changing the pins in them, unfortunately the video has since been deleted.
Try searching using the term, "oilite. "martincom wrote: ↑Fri Feb 04, 2022 9:14 amMark DuVerger was the author of the video. I offered some suggestions to improve the rebuild, as comments to the YouTube video. Mark disagreed with most of them, especially the adding of a grease zerk to the hinge arm, to allow for lubrication. He claimed the bushings were "Oilrite" brand and did not require lubrication and implied lubricating them would be harmful. I disagreed and could find nothing in the NAPA specs to indicate they were Oilrite.

Mark took the video down shortly thereafter. I'm not sure if it was because of our disagreement or the fact he is doing the rebuild for a fee, as some form of side business. Mark frequently posts here, so you could do a search for his name to find his user name and PM him. He also hosts another sweptline forum, though I can't remember the name of it.
I've got a couple photos of the hinges after rebuild. It is pretty straight forward. Mark utilized and end mill chucked in a drill press to "mortise" each side of the hinge arm, so the bushing would be flush or near flush. I sourced the end mill from McMaster-Carr, so I was able to check my order history for what I utilized:
Carbide Square End Mill with Two Milling Ends, Uncoated, 4 Flute, 1/2" Mill Diameter, 3" Overall Length PN:8889A25
