Title: Removing Hinge Pins
Post by: Clewisiii on December 17, 2024, 05:53:03 PM
Can anyone talk through the process of removing hinge pins. Should I be able to beat them out or will a press be necessary.

Bonus if you have pictures.

I can relate to 1971 and 1972 but I would say that others will be the same.

The pins will be swaged after they pass through the last part of the hinge.   This swage will need to be ground off before pressing out the pin.   And then reswaged when the job is completed.

Pics of mine. I do not have a flat swaged side. It might be mushroomed.

What do your replacement pins look like?   That is, if you have replacements.

There is another possibility in that the pin, just under the head could be knurled so as to use this as a method of retainment.

But, the look of the end does look like a swaging of the whole end.

There is a kit for front door at caddy Daddy. No kit for rear door. Only the fronts really have any play so I think I am going to just do them.

Rock Auto has the replacement bushings for both front and rear doors, but no pins.

I did some of the pins on my 57. They were knurled under the head. The end of the pin is just tapered (not swaged). I used a punch and a hammer to hammer the pins out, same method to get the new ones in. If you find yourself having some difficulty, heating the hinge up with some MAPP will help greatly.

Well one is pushing out nicely in the press.

The other one is doing something interesting. The pin is not moving but the head broke off. Maybe i can press it in the other direction now.

Looks like heating is required.   Never seen a head come off like that.

I notice that the one you moved has beautiful ferrules at the head to maintain retention.

These pins are decades old, probably rusted between the pin and hinge wall. Heat it up well with mapp, they'll come out. As a bonus, you can heat up the bent end of the punch until it is yellow-orange and straighten it out while you're at it.

Don't forget to temper the end when finished straightening.

Get it up to temperature and then quench in oil.

I ended up just removing the hinge and used a vice and a socket to press mine out.
This was on the 70.

He is using a press to get them out which is probably the best way but of course the china punch couldn't handle it when the pin hit resistance.

Summit Racing offers a "Bob Drake Hinge Pin Pullers TL-100".
Hinge pin puller (https://www.summitracing.com/parts/bdr-tl-100?seid=srese1&ppckw=pmax-toolshttps://www.summitracing.com/parts/bdr-tl-100?seid=srese1&ppckw=pmax-tools).  Other vendors sell the same tool as well. It will work in some applications, but not all.  It will not work with hinge pins that have a large diameter head (ask me how I know).
