Removing Rusted Hinge Pin

I've got a big ol' heavy steel door with a rusted out hinge pin. You can't tell from the photos but the hinge pin is completely sheared through and each segment is rusted in place. Luckily the other two hinges are holding, but the busted hinge is making the heavy door difficult to open and close. The question is how to remove the rusted pin segments. The pin seems to be "capped" at both ends so I can't just pound it out from the bottom.

That's gonna be hard to do. I assume the hinge is welded to the door and frame. A 4" side grinder with a "cut wheel" would allow you to cut a 1/4" or so (cut horizontal, then vertical from the top) section from the top part of the hinge. This might remove the "capped" area of the the top pin. I suspect it is welded in that area. Repeat the process for the bottom and then hopefully drive the pieces out. Good luck- keep us posted.

Might be broken because it is not in alignment with the other two hinges. Maybe cut/grind the whole thing off and weld on a new one. Beauty of a steel hull.

If you want to just change the pin. Grind off the top cap. Soak with penetrating oil (one with methyl salicylate) for a few days and mechanically agitate occasionally. Then hammer it down and out with a punch. Maybe add a little (or a lot of) heat to the barrel.

Have fun.

This would be my approach.First,I'd remove the paint and check for a bottom cap.If there's a bottom cap,I would grind it off.Then, I would soak the crap out of the hinge, with a quality penetrating oil, off and on through out the day.Lastly,I'd use a steel drift and try to drive the hinge pin up.If I was planning to reuse the hinge,I would just drill back down through it with the proper size bit,and install a new pin with anti-sieze paste.This is the way I'd do it.

Any piece if steel that will fit inside the hole, e.g. Another hinge pin or something strong enough and substantial that you can use a large hammer (32 oz ball pein is my choice!) to drive the "drift" so that it drives out the old pin.

IMHO, if that pin is toast, they will all be close to it. I would remove the door and redo all three hinges and pins. I would also add a zerk fitting so you can grease the hinges.

I would use a brass drift so as not to further peen the steel pin and lodge it even tighter in the hole. I do agree with removing the other two hinges and installing grease zerks. I did this with a trailer door hinge and it solved a lot of future issues.

I agree with removing the door and replacing all three. It will prevent future issues that can be so aggravating. By the way that is a beautiful yacht!

I have used those before with a dead blow hammer and had them mushroom on the end and get stuck in the hole.

How would you add a zerk fitting to a hinge? Why not just oil it from time to time?

If it's big enough,it can use a special hinge pin with grease ports machined in and a zerk on top.Good ones came with a cap for the zerk.

Drill and tap the tube with the same thread as the zerk. They do not need much of a thread as they are quite shallow.

And the pin is much softer than your hardened steel drift and will certainly damage and possibly mushroom the pin. Tradesmen generally don't use steel on steel but I guess that's up to the individual.

Thanks for the advice everyone. I am going to try a combination of the suggested approaches starting with drilling/cutting/grinding off the ends of the hinge pin and hitting it with penetrating oil. I'll follow up with a note on how it all goes. Also learning lots of interesting new terminology from this thread!

Aha….with you now - you had me wondering re this zero thing - we call them grease nipples, (for obvious reasons), maybe you US people are too prim and proper to use such a term…?

I don't think you could add a zerk fitting to the hing shown in the original photo. Perhaps you could but the grease would just run out the first joint. Oil should work just fine and you can get oil into all parts of the hinge.
