Heat and hammer looks like the only option now. Use a sharp cold chisel and try to get it hooked on the remains of the teeth or get a sharp punch and make a good indent before you try to tap round. You need to hold the frame still, in a well padded vice or on a sandbag.

And you still have the option to weld a small lug onto the cup as a last resort.

It will come out, it just may take some bloody mindedness.

Stand on the frame and use a cold chisel and a lump hammer and work the cup round.

Carefully! :shock:

Two options which i have done in the past.

1: Get local welder to weld a metal bar to the drive side cup and axle. use as the wrench. Done this a few times while I was managing a shop :D

2: 5 tonne press! from the drive side the plastic cup will have no chance of stoppin the axle poppin out!! Then you will have to cut the remaining drive housing into 3 and then knock out he pieces. and same for t'other side :twisted:

I would just J-B Weld a cup removal tool to the BB, wait till it dries, then turn it out.

There is no such thing as 'never' when it comes to bike maintenance. Your LBS should know better :lol:

At this point I would hold the frame over a vice horizontally and grip the outer flange of the BB in the vice very tightly and then turn the frame round slowly....

Will let you know tomorrow... going to me parents for the weekend (to the good ol' home-state, some 200 miles away). This is where I have a vice available, so will try there. Also will try tapping round the cup if the vice fails.

So will keep you posted about the progress... and I was just thinking, I (hope I'm mistaken) think in the LBS they turned the wrong way. They tried counterclockwise, so if it has to go out clockwise it's probably even tighter now and that's probably the reason there ain't no teeth on the drive side either anymore??

Well, first have to do the dishes and then it's time for a bit of a kip... and tomorrow it's me and Mr. BB showdown ;-)

YAY!!! It's out!! :-)

Thanx to my dad who had a big hammer (about 10 lbs) and a gas torch... We hit the axle out to one side and when the axle/cartridge popped out, I just had to remove them cups. The plastic one was easy, now I just have to get the last piece of the aluminium cup out. I repaired the threads on the plastic-cup side with an old BB cup I still had (from when BB's was just a left and right cup with an axle and loose bearings).

THANX FOR ALL YOUR HELP!!! Me is really happy now, one more S-bike saved from the scrapyard (and I thought the 1994 Rock Shox fork holding air was my only luck on this bike).

Off to the powdercoater now...
