I have a FSA BB30 crankset, and I want to take it off and replace the BB bearings. But looking on 'how to' websites I've lost an important part, that allows you to take off the crank. there's a plastic screw in bolt, that the inner bolt pushes against when you unscrew it, almost like a self extracting crank, but I've lost the outer bolt thingy. whats it called? as I can't find a replacement anywhere.
Or can I just hit it with a hammer?
Do you mean the retaining nut?
yeah i think i do, possibly the M25?
so, do I definitely need this to remove the crank, or, can i just hit it?
think I've got it, will this do the trick?

Are you after the flibble flange?
Ah, you mean the pedal hanger looser nutty bolt.
