Hi, I've just stripped down both my '84 doors. I had to cut At least 1 stud on 3 of the 4 hinges and 2 of the are very stiff / binding up. Given all this I was thinking of replacing them. I've noticed several companies selling pattern hinges on eBay and wanted to know if anyone had an experience of them? With a genuine set costing £126 on minis pares I'm hoping to find a cheaper alternative

Thanks

Chris

Carefully cut the broken stud flush with the hinge and drill it out. Either retap the thread to normal size if it's cleaned up nicely or Helicoil back to standard.
I did my lower hinge last week - takes about 20mins all in.

I never worry unduly about stiff hinges as they help stop the door swinging...

I replaced 2 studs in my hinge the other day. You need M6 bolts about 30mm long.
Its an easy job and it was a lot easier to remove the hinge pin and repair the studs rather than try to remove the whole hinge as the bolts are seized in my door.

I used 1/4" UNF as per the original spec - nothing more annoying than needing two different sized spanners (especially a metric/imperial mix) on the same component to finish a job.

Thanks for the tips guys. So are the studs permanently fixing into the hinge? I.e. is the only way to get them out, to drill them out? I don't have a tap, could i weld the new bolts in?

You could try and get hold of a decent set of used hinges, I'm sure some of the classic mini breakers who are traders here on TMF could probably help.

Genuine hinges had the studs theaded in, non gen are welded

They are welded in so will need to be drilled out. I drilled a hole put a 1/4" UNF bolt in place then put a blob of weld on the end. Then once welded cut the head off the bolt with an angle grinder. Worked a treat till I sheared it off again when refitting

Mine must be non-gen ones then.

Genuine hinges are both threaded AND welded.
The studs are threaded in to the hinge, and then tack welded on the back to stop the studs from coming out.

If you don't feel up to the job, I have a box of hinges.

Mine were threaded and welded. I cut the weld off and the broken stud turned out.

Thanks for offer, I'll have a go at fixing them and PM you if not.

If you replace the stud with a bolt, can you fit it in from behind? The C section of the hinge looks too tight to get a 30 mm bolt into.

[Vipernoir]

You need a bolt that is about an inch long - there is not enough room to feed it through from behind without removing the hinge pin, which is something else to go wrong...
I cut the head off the bolt, clean up the threads and use it as a stud screwed in from the front. Tack weld on the back and job done.

Thanks, I'll give that a go
