I've gone and done it now!

not sure if it was over-enthusiasm or the plastic cap had just UV ray degradation, but I've managed to remove the entire outside of the cap but left the threaded part inside the crank. so i'm not getting a socket or crank puller in there now!

anyone suggest a way to dig this out? could I dissolve it was acetone or something equally nasty?

thanks.

oh, yeah - I need two "Sugino" dust caps, too!
