Removing a REALLY stuck Square taper crank – HTF

When you eventually get to the nds cup / bb removal use a big g-clamp to hold the splined tool firmly in place so it doesn’t slip off / mash the splines.

I really can’t believe someone suggested cutting through a hardened steel axle with a hacksaw…..

Good man, well done.

Bb came out so easily too. New one in and cranks on. Anti seize applied

Victory!

Glad it’s out but you should have gone for outboard bearings.

Nice colour frame, what is it?

Happy to be wrong! 😀

Well my hack saw went through a hardened steel Abus D lock shackle just fine, an axle is not so different. Took a new blade. But when your son has lost the spare key as well as the main, you’d be surprised what you can do with a big vise and a bit of effort. Next step would have been a portable angle grinder, but I thought I’d spare the investment.

A good quality bi-metal hacksaw blade will cut hardened steel, although it’ll take a bit of work to do.

I always just put the crank bolt back on the BB to hold the tool on.

The bb was NOT the issue – it was the CRANK ARM
