hi guys,

external hinges seem a little expensive so was hoping to refurbish mine instead (replace bush and pin) does anyone have a how to on how to do this? have been looking on the forum and cant find anything yet.

cheers

I have done a bunch over the years but not seen a how-to.
1. There are 4 hinges and all are different.
2. All the pins knock out upwards as viewed on the car. Do NOT try and do this in situ.
3. I shaped a piece of aluminium to support them properly whilst knocking the pins out with a hammer and pin punch.
4. I made a stepped punch to remove and press fit the bushes under my drill press.
5. The bronze bush in them is only 1/32" thick. If the old pin has worn through the bush and ovalled the hole, you cannot fit a standard bush. It needs the hinge tongue drilled out an oversized bush made, or find another hinge. I have made some in the past, 9mm OD x 1/4" hole, from bearing bronze.
6. After punching the new pin in, sand the top of it level with the hinge.

This comes up often, one link I have bookmarked which was posted a while back that I think is very handy is http://www.drjing.com/Mini/TechFiles/HingeRebuild.htm also handy is the followup http://www.drjing.com/Mini/BLOG/DoorHang.htm

Was gonna pop up the links above someone said the aus hinges back markings are different or something

True, some hinges I have seen are marked with UL, UR, LL, LR etc instead of numeric but then again I have seen a few that have no markings at all either way though the guide does a pretty good job of showing the basics of how to refurb a hinge.

legends. thanks guys.
