OT: Carbon fiber crank removal question

[Phil, Squid-in-Training]

Here's a gem from rec.bike.tech:
--------------------------------
I removed the dust cap and retaining bolt on the non-drive arm, but the
two arms don't come apart. From the downloadable pdf instructions it
appears that the two arms are connected with a spline, but I can't get
them to release. I wrapped the left arm in a towel and put a 2x4 over
the inner surface and whacked it with a hammer but nothing. The bike is
brand new, about 150 miles. Any tips?

Thanks,
Wayne

No - you're doing it right. 2x4 and a hammer. Should work every time.

That's wrong on so many levels. The obvious tool for this crank removal is
the adjustable wrench.

An adjustable is too specialized. That's why I ride a round with a
Vise-Grip clamped to my seatpost.

The obvious answer is, get a bigger hammer. something in the 10lb range
should take that sucker clean off. like butta.
