Stripped Crank Thread - Not Pedal Thread 🙁

[Mr Weirdo]

Ride it up the road with the bolt out it will loosen in a 100 yards or so. Stop pedaling immediately.

Thank you GIGFY...I guess best not to do this on a wet day then

VAR makes/made a tap for the 23.35mm Verot removal thread;
have one in me infirmary

possible they make/made one for the 22.0mm as well...

Pullers for 23mm (Spécialités T.A.) and 23.35mm (Stronglight) are readily available, and a useful addition to any vintage bikewrencher's toolbox.

If you can find a tap in one of those sizes, that would be my preferred solution. Not sure if a 22mm tap will do much good anymore.

Don't beat yourself up, I've done this (more than once).

I'm guessing then the quality doesn't vary that much

Yes quality is hugely different...but your trying pull off a bike crank with is hardly held on 8n the first place. If you were pulling the output gear off a volvo f16 then a £10 puller would not be my first suggestion in terms of quality!

 

[Tootyred]

Just remember to leave the bolt in, undone slightly , to give you something to pull against....else you wil be ripping the taper out too.

This is all a lot of ballache to desperately try and keep a damaged arm in service, that at the end of the day is still damaged.

Why not spend comparable money (£30-40), and a whole heap less time, and just buy a replacement arm.

Use the other one as a door handle or something if you have a romantic attachment to it.
