Removing sealed bearing botoom bracket

(1/4) > >>

Andyboy77:
Is there a special tool out there to remove sealed bearing bottom brackets -gently?
I saw some people using a screwdriver or something similar and a hammer, but all the bottom brackets suffered due to that procedure quite a bit.
In other words they looked pretty fooked.  ???

Many thanks in advance!  :daumenhoch:

Bit of copper pipe as long as they've been not installed for a long time and the alloy has fused with the steel.

Obviously you don't want to beat the shit out of them but noone ever sees the back a few dents wont affect their performance.

rooski:
Hammer and something rigid but not too hard to knock them out, think I used the a steel bar with a plastic cap on the end.

They will get slightly damaged though, the aluminium housings are pretty soft.

They are in since 1985. No, I don't want to beat the crap out of them. But I get the idea though that it won't effect their perfomance, if I'm just gentle enough.
I don't have the heart to do it that way I'm afraid, so I was hoping some genius came up with a tool for that kind of exercise. But obviously that's not the case up until now. Too bad!  :-\

Tap round the cup, imagining it as a clock, 12, 6, 9, 3, 12, 6, 9, 3 and so on.
