Miche Supertype left crank screw damaged

[shimans]

Hi to all!

I have Miche Supertype carbon (compact) crank set. I need to replace a screw from the left crank arm because it is damaged, so I can't tight it anymore. I couldn't find any possible way to get the screw (it has in center 8mm hexagonal hole) out of crank arm, and maybe to make a new one to replace it. Did anyone have a problem like this, or have any idea to resolve it. Here is a image of crankset:


Thanks with best regards

Contact the manufacturer to see if they have any cheap replacements.

I sent them a message, and expecting reply now. I know some mechanics who can make a new screw for me, but I don't know how to get it out of crank arm.

I will take a picture of that crank arm and upload here to see how it looks like.

Yes sorry I guess I should have asked that. Let me see take a gander (look) after you upload the pic.

What exactly is the problem with getting it out. Sounds like you need a 8mm allen wrench. If its frozen soak it with "Liquid Wrench overnight and give it a sharp rap once in a while. An impact driver would help. Although with carbon stuff I would not get to rough.

If its stripped from over tightening and spins but does not unscrew than you may need to drill it out with a drill bit smaller than screw threads a bit at a time and than collapse the screw and get the bits out. Maybe a job for machine shop.

If you can get the good side screw out you can find a match in a hardware store unless its special.
Use blue or green locktite screw holder on re installation

Wow, I just looked at the price of this crank, man definitely take it to a machinist to remove the screw and make sure the female thread is not striped. Could be just chased and cleaned.

Yes I did. I sent a message to MICHE factory. They responded to me immediately, and said to send them the damaged crank arm, to replace the screw without any compensation and sent me back. And so it was! After max 2 weeks I had a repaired crank arm with new LONGER screw, all for free. That was at May 2010, and until today I didn't have any new problems!

Cheers
