Okay... what the heck do I do now?

[lgrinnings]

Alright, folks-

Pulling apart this 1920 or so Crown and the non-chainring side Fauber threaded bearing cup sheared off. How the heck am I going to get the rest removed? My thought is to drill a spot in the bearing cup edge that lines up with the crank thread slot, insert a keyway that spans both parts and use the crank to spin it out. The bearing cup is hardened though, so I don't know if drilling it is an option. Any and all suggestions are appreciated.

Thanks in advance!

Ouch!

I wonder, if you hammered(or drilled first) a punch in where the groove is and then tried to turn the crank, if it would turn it out? Heat BB housing first of course

Do you have replacement cups?

I have a few, but they're sort of committed to other bikes. There may be a bunch with my dad's collection, I just have to check.

I'd try bricycle idea first, but if it doesnt work, drill a second hole appropirately spaced for somerhing like this:

Nothing fits like the original tho.... fauber to fauber doesn't guarantee a like thread fit!

Yep. that's easy, two new holes and a spanner. Now finding a replacement that's not worn down beyond the point of uselessness could be almost impossible. Fauber BB parts seem to be really soft and wear out fast.

I'd drill one small hole but just deep enough to get the tip of a punch in there, then "unscrew it" by hitting the punch with a hammer. easy squeezy
