Bianchigirl,
Thanks so much! It never occurred to me that the ring would be what the bolt pushes on to self extract. Cool!
I actually have some tools where i live in europe but this is a USA job (visiting family) and I could potentially spring for the BB tools and bring them back. I have some experience tightening around bearings to get them just right, mostly hubs. I think I can handle it. Of course I wont know till I am faced with it, and the funny thing is the LBS where it was purchased by my brother still exists (Trek dealer now) and it would be fun to bring it back there for a little work 40 years later!!
This is a great forum. the one thing I didn't understand is about uploading photos into an album... I tried to upload into my post but there was a 10 post wall... is there another method?
