Oh #$*& - Need Helpcelliott
Mar 12, 2003 12:35 PM
Just bought a pair of FSA Cranks (ISIS) and matching FSA Bottom Bracket. While talking to FSA, as no installation instructions came with neither the cranks nor the bottom bracket, they informed me to mate the inner aluminum ring of the crank to the outer aluminum ring of the bottom bracket. So, I greased it up and went to town.

To make a long story short, I rounded out the 8mm allen head and now I can't get the crankarm retaining bolt out of the crank/spindle.

My thought is to drill a hole through the retaining bolt and take a left handed tap and tap it. Then using a left handed hex head bolt try to remove the retaining bolt.

At first, I thought about an EZ-Out, but they're tapered and that might put more stress on the joint between the retaining bolt and the spindle.

Has anyone else messed up like this? Is there a better fix?

Was it an alloy or steel crank bolt you stripped? If it's the alloy one, you can cut a notch in it with a small hacksaw blade and turn it out CAREFULLY with a flathead screwdriver. If you used the steel bolts, you can do the same thing, but it will be a lot harder to do so. Otherwise, you have to be inventive. I have seen a friend do this in a shop before... he drilled into the crank bolt on an angle and then used the drill bit as a lever to turn the bolt. Without drawing a picture, it is hard to explain.

Just whatever you do, be very careful not to nick the carbon in the crank.
