Lower hinge pins

Postby johnnyj » 27 Mar 2017 21:04

I wonder if anyone else has had this problem: The lower hinge pin has sheared around the top splined mounting, leaving the top of the whole hinge assembly flopping around. I have removed the "door side" part of the hinge, leaving just the "a-pillar side" in situ. The remnants of the pin are firmly seized in the door-side part of the hinge, with the top sheared off.

Getting the old pin out is proving a nightmare. I can't drill it out as the top hinge fouls the drill and makes for a cut at the wrong angle. I have a spare entire hinge but the original is welded in around the inner and outer A-posts, and I can't get the grinder in to the outer as it won't fit without removing the front wing (which I just welded on - shoulda' checked first, I guess!).

Any ideas for getting at seized lower hinge pin out?

Thanks all (photos to follow)

Me, too.

I noticed the DPO had forced a long bolt in the hole from the bottom (with 1 1/2-inch shank hanging down), but the hinge is loose and the door has to be pulled up to latch.

I look forward to your responses.

I have always removed them with a long slim drift and a hammer.
Placing the drift and an (as shallow as possible) angle to the lower part of the pin.

The upper ones are two part and often welded in place, so more fiddly to remove!

Hi and thanks Beans. I finally got them out, but not before an awful lot of drilling, heat and hammering!
