I attempted to remove a door from my Mk1 today, I was planning to renew the hinge bolts.

 

Starting with the 4 bolts in the wheel arch, 3 came off, but the top furthest one in would not budge. It is so rusted, and so hard to reach, I could not get a socket or ring to fit on it, tried all sizes metric and imperial. Put an inspection camera in there to look at it, see attached photo.

 

I am at a loss of how to get it undone, any tips?

If you have one or access to one you could try a deep socket of the correct size. If not then as you intend replacing the bolts you could use a Drexel type tool to cut the excess thread off and then get a normal socket on. You could also try using a nut splitter. I am saying this without knowing how much room to work you have.

You don't need to remove the hinges to replace the vertical hinge pin.
Just drive the old pins out upwards with a pin punch and fit new ones.

Thanks, but it is very hard to access, however I might try something like this (imperial equivalent)

I wish, that was the first thing I tried, I think it has been badly repaired in the past, the pin will not budge, hence the need to remove the hinges.

What I found when I had, and worked on my 1960 Mk1 Morris Mini Minor was that the bolts are not formed and made in the hinge, you can get them out with the full thread as well with the bolt on.

 

I had a similar problem removing the nuts, and eventually, the lot come out, which made life nice and easy. As they are 1/4in bolts, they are easy enough to work with.

 

They are a bugger to get at, but when and what ever method you use to get at them and try to remove them, you can get them out in one commodity. So if you have to force something on, don't worry, the thread as a whole can be replaced. The hinges are also brass, mine were, so easy to re-tap if needed.

Thanks, but the bolt is so rusted I need an extractor.

 

I've found these, which have the correct size, so will try and report back.

should be 1/4" UNF so 7/16 AF

[beardylondon]

other bolts are 7/16 AF, as this one has rounded/rusted, so will use the 11mm bolt extractor

So I did it, ended up using the below to remove the dodgy nut I was on about above, which was rusty and has become tapered strangely.

On top of that, there is no way I could of replaced the pin and bush with the hinges on the car, as the hinges has previously been bushed in the past and the pins where rounded off and needed a precise centre punch in a vice. And thus to make sure the bushes went in straight, a vice made it a lot easier. Also one of the studs was rusty and came out, so it needed a new stud cutting to length and super gluing in, so again easier off the car, and also ensured no damage to paintwork.
