Bottom Bracket removal

What a pain in the arse! after a bucket load of sweat and breaking an adjustable spanner i still cant get the drive side side of me BB out! arse. any helpful hints so i dont have to take it to Edwardes on saturday and pay em to do it.

Cheers

spray wd-40 between frame and bb might help

What threading is it... and are you sure?

You might be tightening it.

its british threaded, one of those shimano isis thingies with all the little teeth. why would anyone make something so awkward and fiddly?? Yeah i read the back of the pack the tool thing came in n following that, worked one side so pretty sure im goin the right way. bloody bikes!

Drive side is left hand thread. Put the tool in a vice, frame on top and turn complete bike clockwise. If no vice, better to use a 1/2" or 3/8" drive (whatever Park use) with a breaker bar. Or if using adjustable make sure tool is bolted through BB or to axle so it cannot slip. Give it a few sharp bangs to try and shock it free.

Yeah. To clarify, they're typically differently threaded on the drive and non-drive sides. You may well have been tightening.

Hi all, I have consulted the various guides (Park Tools etc) and I cannot for the life of me get this BB off my bike.

Any tips for making this easier? I really can't be arsed to take this down to my shop, I just bought the removal tool, I should be able to do it my self but the drive train side feels like concrete, fucking piece of SHIT!

EDIT. This is a sealed BB by the way.

you turning it the right way?
Driveside is reverse thread.

English - clockwise or forward for removal.

Italian - anticlockwise or backwards for removal.

What frame do you have?

dmczone, I've got a Brick Lane Bikes track frame so am turning it clockwise on the drivetrain side, the left side...

I've never really understood that...

ISO threading - Why design a BB shell so that the BB could potentially unscrew when pedalling?

I'm starting to think the only solution is the LBS.

Try putting shit load of WD40 in there and leave it to soak. Other than that you'll need a vice. Put your BB tool in there and turn the frame.

you'll need a vice

I have many, although not the metalic tool-based kind. Boom-Boom.

LBS here we come, I had a feeling it would come to this.

I am about to remove a bottom bracket for the first time, it has cottered cranks will the tools in this kit be good enough for the job?

Yes.

How old are the cottered cranks? You may require some form of hammer a peice of pipe, a decent set of pliers and some WD40. ;)

You'll need a hammer and the correct sized spanner for the bolt, and a lock ring remover. A special kit isn't necessary.
But if it has been on the bike since 1972, see below:

also put a towel underneath the bike and get ready for some very smelly liquid to pour out.

Ah, nothing like your first time down at the bottom...

are you saying you're a bottom virgin? you need to do exercises beforehand, and be prepared for a little seepage. yes it does hurt the first time.

maybe give it a colonic.

Not 100% sure this is bike related?

OP you seem to have some unfinished sales business...

Nice bump.

On a slightly related note, I recently got a coventry eagle frame from the local dump for free and stripped it down... It had some nice GB bits on it. Anyway, everything came straight off, even the cottered BB... Cotter pins had been properly greased so had the BB cups. It was dirty as fuck, but everything came apart a dream... I was really surprised!
