What is peoples preferred method of removing stubborn door pins?

Hit with hammer
Heat with torch & hit with hammer
Drill out pin
Angle grinder through brasss washers to spilt into three, then hit with hammer

Hello Richard,

I have never done this specific task but lots of similar ones.
Soaking with a penetrating fluid such as plus gas for a few days may help.
A good solid hammer and pin punch is required. Heat certainly helps a lot but will damge the paint, which may or may not be a problem for you?
Consider jacking the car as close to where you want to remove the pin (I guess the front as they get much more use generally) on the principle that any hammering is more effective onto a solid base.
The chance of drilling it out accurately is about zero. (Is the pin hardened, probably?)
I don't know what you would gain by removing the washers?
If you have the facilities making a specific screw driven press could work, if there is room to get it in (there should be even if it is done from below.)
The weak area in such a tool is the length of the pushing element which could bend. One answer is to make it much shorter and add lengths of round bar as the pin moves. Mind you if it can be moved an inch or so it probably then will drift out?

Hi Alec, I will give the blowtorch a try. The car needs a respray, so not too concerned about the paintwork.

I have had to use the grinder before in the case of broken pins. If you cut through the washers and pin, you can separate the pin into three pieces. The two on the car then drift out easily and the centre piece can be drifted out in a vise.

Hello Richard,

try and get to a dull red heat if you can. Have you tried just the hammer in case they are not as tight as you suspect?

Last time I renewed hinge pins on a Triumph (many years ago!), I just used a stout punch and a hammer and they came out without too much effort.
At the time, replacement door pins weren't available from Triumph, but they were identical to those fitted to the Austin 1800, which were available separately!

Yes 2lb club hammer. Shifted a bit then stopped, possibly the wear point on the pin has caught as the hinge is stiff now, whereas it was flippy-floppy :) :shock:

Been playing welding today and Bradley has been making & using a Servo dismantling tool for his MkII 2.5. :roll:

Just an update on this side. Got it out by slicing through the brass washer with a fine (1mm) angle grinder cutting disc. Had to have the centre part of the hinge electro spark eroded to remove the very stubborn part of the pin.
