Stripped BB splines

[mtncampy]

Looking for tips on how to remove a 1994 Record Bottom Bracket - the splines have been stripped out. This is on the Drive side. The non-drive side, which includes the actual spindle cassette assembly came out fine.

thanks

the last resort is to take a hacksaw, cut the BB carefully in three places, just enough that you can break it out, and then chase the BB threads.

An idea is to use a large nut and bolt.

Pass the bolt through the shell and poke it out of the seized cup. Screw on the nut with a washer.

As you tighten the nut, it will grip the cup and unscrew it. The drive side has a LH thread, so by tightening the nut clockwise, it will turn the cup clockwise too.

If you have Italian threading, ie the drive side is RH thread, do the same, but the other way round - if you see what I mean.

Pass the bolt from the outside of the drive-side cup, screw on the washer and nut inside the BB shell. With a long socket and extension, you can tighten the nut. This will grip and turn the cup the correct way for unscrewing. ie anti-clockwise as viewed from outside.

If that doesn't work, resort to the hacksaw method!

Mick.
