Chewed Crank

[jrussell]

Please tell me a LBS can re-thread a crank arm? my pedal came undone while i was riding and chewed up all the threads in the crank and it cant go back in please help!

[Tieffels]

LBS will not be able to re-thread it, but you can insert a helicoil thingymajig by drilling new hole and treading it.. Should not be the worlds biggest mission.

 

Contact Johan Bornman, master of the de-botch..

I guess you are going to find out hey? Good luck!

Which crank is it ????? the chainring side or the single arm. Remember there are left and right habd threads involved here. Normally not worth the expense of helicoiling it.

Otherwise its new Truvatives in October.....but I cant not ride for so long its the left crank where the pedal screws in

[Johan Bornman]

You choose the right crank to strip. You can Helicoil the left, but not the right. Shouldn't cost too much and worth a try.

Helicoil the company sell bicycle specific kits, LH & RH thread.

That is not a Helicoil, that I'm sure of.

It seems to be a stubby axle or bolt for the Bromton-specific folding pedal.

 

Helicoil kits may well be available in left hand versions, but I don't know who stocks it. It'll be so scarce that you will have to buy the tools (as opposed to get an engineering shop to do the job for you) and that that will cost more than a set of cranks.

 

The left pedal is a standard right hand thread and Helicoil is available for that.
