Topic: '40 cpe door hinge pin removal


Gene's40    -- 10-10-2025 @ 3:36 PM
  I am trying to remove the passenger door hinge pin so that I can mount a new hinge mirror from Carpenter. When the car was restored by the previous owner the new door hinge pin was mushroomed to prevent it getting loose. I took a dramel tool to remove the mushroomed metal. I bought a new door hinge pin removal tool. I have used WD40 on the hinge but the pin is being stubborn. Any suggestions ?

  Those hinge pin removal tools are cute. Hang it on your wall.
Use a BFH with a solid backup. Then when that doesn't work, carefully drill the pin with increasingly larger bits till the pin will finally move for you.

  WD40 is not the right penetrant to use . Ideally use a 50/50 mixture of transmission fluid and acetone. Let it soak good, maybe even overnight and then get out the hammer.

  Alan and Tom have both hit this one squarely on the head.
I especially like the reference to those tools being "cute".

I had just last week removed two pins. Yes, both were drilled to nearly the diameter of the pin and both were then fairly easy to knock out.
I leave about 1/4" of the pin intact (I don't drill through completely) so I can place a drift down "the hole" and have a solid part to hammer against.,
Just be careful to drill straight...

  Another method to remove the stuck door hinge pin is to use a C-Clamp. This method might damage the paint on the top of the hinge.

Place the C-Clamp so the threaded portion is on the bottom, use a bolt of a size slightly smaller than the O.D. of the pin and a socket wrench slightly larger than the O.D. of the head of the pin.

Place these items as follows:
Socket on top of hinge, top of C-Clamp on top of socket, bolt with threaded portion facing up under the pin and C-Clamp threaded portion under the bolt.

Soak the hinge with the best penetrating oil you can find and let soak for awhile. Tighten the C-Clamp until the hinge pin is pushed up out of the hinge.

This method worked for me when working on a 1940 Ford Tudor.

  I built a wooden piece the holds the lower door lip and the use of my floor jack. Should I open the door half way and then try to remove the pin ?

  No.
The door latch is perfectly capable of adequate support, and secondly, opening the door even partially drastically reduces your access for removal., while exposing the door to possible instability.

  I bought Kroil oil and used it daily on the hinge. I've tried the C clamp method to no advil. I've tried to drill from the bottom of the hinge but apparently when the car was restored the re-assembly used hardened steel which has made it tough. I am not giving up !

  One thing you can try but you have to be very careful while doing it, is to use bee's wax as a penetrant. You have to heat the pin up hot enough to get a bee's wax candle to melt on it and get into the hinge. Too much heat will damage your paint and could start a fire. If done properly this method will work. It may take several heating and liquid bee's wax applications to get the hinge pin to come out.

  Gene, I have never heard of a hardened hinge pin. I suppose that's possible but probable? Not likely.
Drill from the top - downward. Start by making a punch mark on center. Then, with a good quality center drill, start the "path". Then move incrementally with drill bits. I start with 1/8" diameter and move up sizes by no more than .032" at a time.
I drill just past the center part of the hinge.

  Mike,
I used my 1400 heat gun applied on the rear portion of the hinge; after red hot I used my center punch and struck from the bottom with a somewhat heavy machinest hammer. Still no luck. I'll try your method of drilling from the top starting with an 1/8 " bit.
