is there a special tool for removing cranks off the new shimano splined bottom brackets? i have the standard shimano tool, but it doesnt seem to work and looks as if it will strip it(doesnt grab enough threads). am i missing the obvious?

The caps work as extractors. It may take a bit of force to get them to break loose.

... if you have the new splined BB, but don't have the self extractors installed, you'll need...

crank remover and "button"SLM

Or you can use a standard crank remover, but you have to use a special "button" that slips into the spindle. This "button" is what the crank remover pushes against. This button is supplied from Shimano if you purchased new cranks. I'm sure you could get it from other sources as well. It couldn't cost more than a couple dollars (from Shimano maybe $$$)!

Doesn't have the "extractor bolts" so you either need to get a pair (or just one) of bolts, get the magic button (I didn't know about this) or get the proper crank removal tool from Park et al.

If you go further and decide to mess with the BB be advised that there is a newer spline tool that looks almost exactly like the older one, but the difference is the length. The old tool will only partially slip on and you will strip the splines off of the BB cups. Then you're in a world of hurt.

I would advise getting one of the excellent books avail. - a little knowledge and some pics is a very good thing - and it's the cheaper way to learn!
