Hinge pins
I'm taking the doors off my 30 coupe. The hinge pins are stuck! I got the two top ones out, difficult but not really. Broke the heads off of two of the lower ones. (?) And I can't get the broken or the two whole pins out. I have saturated them with WD40, heated them blue, and pounded them with a two Lb hammer. I have hit them so much, I'm worried about distorting the hinge or the mounting. Anybody got any got any secret method. The mini wheel pullers from the vendors don't seem to work. Also, does anyone make stainless steel pins?

Re: Hinge pins
How about trying a pin punch type fitting in an air chisel gun?
Instead of WD40 try using Kroil or the acetone/atf mix.

Re: Hinge pins
Terry, there is not really a 'secret method' to these. Sometimes they are just frozen in and the only way we have removed them is to set them up in a mill and drill them.

Re: Hinge pins
When I have a tough hing pin, I usually end up drilling the pin out over half way and using a drift punch the rest of the way. I have never yet had to drill out the full length of a stuck hinge pin. I have done over a hundred hinge pin removals. Heat also helps loosen their grip.

Might help to take the pressure off the door a bit and try a pin press as noted above. Heat is usually a friend here too as stated. |

Re: Hinge pins
A ball joint press might do the trick if you can borrow one,the C clamp might not be able to handle the stress.

I haven't done a hundred but the few I have done were done as posted above. I tape a layer of cardboard around the door post to protect the paint. I will admit that I got my 36 year old son to do the process on the last one that was removed. Chap |

Re: Hinge pins
Of course you need a large c clamp to fit over the hinge post etc. My score so far is 4 hinge pins removed, 0 c clamps broken, this after using a mallet and drift punch, you just keep tightening until “bang” out comes the pin!

Re: Hinge pins
Thanks Guys ! I've been thinking of the C- clamp idea. I may go and buy a sacrificial clamp this AM. I am also ready to apply the some home brew penitrent , ATF & acetone.

Re: Hinge pins
In worse cases I cut the top off the hinge pin and drill the pin from the top side . I drill the pin a little better than half way . I use a pin punch to drive the remainder of the hinge pin out .

Re: Hinge pins
I have read many comments regarding difficult to remove hinge pins. Sorry for all your trouble but I have the opposite problem. The pins in my roadster door loosen all by themselves and every month or so, I have to tap them back in place. If I forget, the doors get loose in the hinges and I know it's time to tap them in again.

Re: Hinge pins
Hoping you try it anxious to hear of your success, the c clamp I use is an older one I picked up at a yard sale. Be sure and orient it so you are pushing up wards.

Re: Hinge pins
Sometimes the pins/hinges get a bit bent, try opening the door part way and then removing them. On my passenger side, this did the trick and made them very easy to remove.

Re: Hinge pins
I had a really hard time with the first pin I took out years ago.
This is MANY years before most heard of the internet ... Actually we were using the Internet in (1968 and 1969 in Vietnam) and later 1970 ... it was called the ARPANET back then. I had borrowed one of the removal tools but the pins were damaged beyond being useful so we made new ones. Did not work very well ... Then I noticed that the pins that Ford installed at factory are 15/64ths inch and the ones I made for the tool were 1/4 inch that is 1/64 larger than the original pins! No wonder we had so much trouble. I had measured the replacement pins as example and they were 1/4 inch (16/64ths) so the pins for tool were made to be 1/4 also. If you read instructions for removal look on Snyders by looking on their web site you will find their pins (for the tool) are 7/32nds or 1/64 smaller than the 15/64ths original pins.

Re: Hinge pins
Benson! I've heard of Arpanet but never met anyone who actually used it. It was only active in about 4 or 5 western cities as I recall. It was followed by the expanded Darpa IIRC That's interesting about the sizes. Thanks for sharing!

Re: Hinge pins
Did you ever get your hinge pin removed? And if so by what means?

Re: Hinge pins
If you don't have to worry about damaging paint , I heat the cowl half of hinge red hot where the pins go through . Heating red hot expands the hinge so that the pins can be more easy to remove . If failed attempts have been made at driving the hinge pin out from the bottom , the pin is probably expanded . This is why I prefer drilling the pin part way out from the top side and driving the remainder of the pin out from the top side .

Re: Hinge pins
I recently had great, even dramatic success using an air hammer with a punch attachment. I had tried a couple of the c-clamp type tools and had soaked the pins/hinges in Kroil for two weeks prior to making the first effort. Could not get the pins to budge with those but the air hammer worked like magic! Suggestions: cover the surrounding body areas with something to protect it, and drop the air pressure down to about 50 pounds. We started off with too much pressure and couldn't control the punch.

Re: Hinge pins
Air hammer works good, but when all fails and it comes time to drill one of these works great https://www.ebay.com/itm/7PCS-Self-C...item3b0e6d1622
This tool has changed my whole outlook on drilling out studs in delicate situations. It would be best to replace the drill bit with a quality one to make it work even better. It works so good that I have purchased a few of them and given them to friends that do the same sort of things like I do. And for the price it can't be beat, even when you use it for its intended use of drilling hinge holes! |

Re: Hinge pins
My son and I built a 30 CCPU from parts collected from Sammy Guthries "bone yard". The cab was off an AA tanker truck which was restored with a much better cab . The cab was in dire state and the pins were frozen solid so I drilled,heated etc etc to no avail . I could see I was on a hiding to nowhere (English saying) and was beginning to disturb the hinge pillar connection .So I bit the bullet and with a thin cutting disc I cut a slot in the hinge and with a chisel I slightly opened it up and the pins then punched out .After the doors were off I ground a flat and migged the slot closed then with the deft use of my trusty angle grinder with a flapper disc the repair could not be seen . Doors went back OK but one pin migrates upwards over time but that will be an easy fix .

Re: Hinge pins
Our local club had a work day last weekend, and we removed hinge pins on a Tudor sedan. The owner had soaked the hinges with kroil for several days. When a hammer and punch didn’t work, we used an air hammer and the pins popped right out.

Re: Hinge pins
For my 30 standard coupe, I've removed my pins with a bit of difficulty and found the drill both sides method, then punch through works best. The "C" clamp shaped press was a waste money! Once I examined the removed pins, I found they were misshaped which adds to the problem of pushing them out without relieving resistance by drilling first.
Does anyone have a surefire means of selecting replacement pins? Some sample pins I purchased of different diameters fit holes in some of my hinges and not in others. Since all hinges are removed from the body and doors, it will be easy for me to drill the same size holes in all hinges and use the same size pins. Can any of you provide what worked uniformly for you as to size of drill bit and hinge diameter? Second question - any benefit of using stainless pins versus steel? I'm not concerned over the authenticity, rather am focusing on the functionality. My thanks. |

Re: Hinge pins
This is an old post but I will hopefully help someone in the future. For over 60 years I have been dealing with this problem of removing pins, screws etc that do not want to move. I have tried about every means to get the task done. When it comes to the final option of drilling them out, there has been the fight of getting the hole where you want it. A couple of years ago I was watching a Youtube video of various methods and there was one particular tool that impressed me and it was inexpensive. It is used to drill guide holes for hinge screws, but the presenter said it was the best drill aligner he had ever come across, I agree also. The first thing you need to do when you get one is scrap the cheap drill bit that comes with it and replace it with a quality bit. In the past few years I have used it a number of times with success. Here is a link to the tool. Best of luck

Re: Hinge pins
Stainless steel pins are available oversize at 0.245". I used a 0.250 reamer to size the holes in my hinges as they had some wear. I suggest a reamer rather than a drill bit as the size will be more precise. I also machined the top side of each door side of my hinges for a thin nylon washer to eliminate the metal to metal contact which is a source for chipped paint and rust and makes the operation smoother.

Re: Hinge pins
Hey desotoguy, that was the information I was seeking. I understand the location where you place the thin nylon washer. Could you send a picture? My care is a user, not a point car and I like your suggestion. Thanks!
