Bottom Backet Removal

Raam

I want to take a BB off a bike.
Either end looks like the ends here...



I have the lock-ring off, but what tools do I need to get the rest of it off?

The tool you need is one like this

Your teeth

OK, I'll give that a go and get back to you...

But before I break my teeth...

those cottered cranks came off very easily. I was expecting a lot of trouble, but they were simple to remove. It's actually the front mud guard that is causing trouble. I'm trying not to break anything in the course of stripping the Jack Taylor frame, but the nuts for the front mudguard are firmly rusted home. I've left them soaking in a WD40 equivalent.

Finding it hard to find the right link to take of the chain and I couldn't find my chain breaker. It's around somewhere. I may end up smashing hell out of it to get it off.

The headset might prove to be tricky. There is a bolt at the very top that looks quite rounded. I tried unscrewing some bits lower down, but that just let the ball-bearings fall out, so I tightened that up again.

Handlebars and wheels came off with no problems, as did the brake-sets.

Seat-post slipped out nicely after letting some oil work it's way in.

Sounds like you're making pretty good progress, mudguards aside.

All in good time . I took a few before I took it apart. Will snap a few more when it's all in pieces and post up then.

I'll be round at the weekend with a battery powered angle grinder, just show me what needs shifting.

After building the planet X without needing the angle grinder I have to get some use from it...

If you can find a length of pipe or similar to slip over the end of your spanner you can often get enough extra leverage to get the nut to move. I've seen all kinds of things used for this - the most extreme was using one of the long struts from a car roof rack.

Thanks Rottenhat, unfortunately, it's the screw head which is starting to strip. There is a bolt on the other side, so I am finding it is handy to try hold the srew in place while turning the bolt. It worked on the rear mudguard
If it comes to it, I can just hack saw the thing off.

My main concern is the stem...
Any tips for trying to remove an almost rounded nut?

Drilling it out? I don't know. I've never tried it. But if you do that, the nut and headset are gone.

I haven't had a proper go at it yet. Looked at it and decided to leave it for another day.

Why would the headset be gone if it had to be drilled?

Shall I get you to do the cabling?

If there is enough metal left on it, you could use a dremel to create two edges opposite each other and clamp onto them with an adjustable spanner

Pair of mole grips may be able to get enough leverage

Yeah I was gonna say use them. if you set them a bit too tight they ruin good bolts, but are great for forcing a rounded bolt no problemo.

Use a Vise Grip.
I've one in the taxi you can borrow if you want.

Thanks Hermy. I'll have a stab at it and if I've no luck I may take you up on the offer.

They're the same as mole grips!

The Mole Grips mentioned are made by Stanley.
I prefer the American made Vise Grip.;)

Vice grips are a great all-round tool, you should own one. Their jaws have notches so it can act like a box spanner, and it is also useful for freeing rounded nuts. If that tool fails I would repeat Gavin's advice to carve out two straight edges opposite each other, and use a spanner on that.
