crank removal

[tazz]

 Hi Hubbers, I'm looking for ideas to remove my cranks from my mountain bike - the drive side thread is stripped so the crank extractor doesnt work - cranks are being replaced so total destruction is an option but preferably as last resort pleeeeez help

[Bike Mob]

what kind of crank?

 

Isis?

 

[JA-Q001]

a Block of wood and a hammer, works well!

Truative entry level crank with sqaure taper - nothing extraordinary

[tazz]

I have a sealed BB so the shaft can't come out that's the procedure i used to replace my original BB

I have the same problem with one of my older frames, extractor thread is stripped, also standard square bb.

I don't think a piece of wood and hammer will work?

 

Any other ideas????

There was a thread about it a while back, do a search for posts by Johan Bornmann on crank removal.

 

 

 

EDIT: Did your homework for you

 Mission acomplished

lay bicycle on it's side supported with packing to protect frame hammer and cold chisel work your way around the crank. It came off quite easily minor damage to surface of crank arm and chainring

 

Thanks hubber for all the tips and ideas
