Crank stuck in a BB30

first off, it's an abused carbon bike...a daily driver that has issues. The bottom bracket is trashed and the crank is an FSA SL-k. I have used penetrating oil and whacked with a mallet as much as I dare without shattering the frame. Any suggestions? As always, grateful in advance.

Did you first use the self-extracting crank bolt assembly that comes with the crank? There is a two piece tool that includes the outer retaining nut (this is reverse-threaded on the outside) and the inner crank bolt. Just leave the outer retaining nut in place and unscrew the inner crank bolt and that will separate the crank and allow you to remove it.

Oh yeah, got the non drive side crank arm off, no sweat. Pulled the wavy washer and th cap over the bearings. What I have left is the spindle through the BB and it will not budge. I have "tapped it with a mallet" no movement, I'm waiting on the penetrating oil, hopefully it will do its thing.

IMO you should be able to whack it with a mallet, or try tapping it with a hammer (use a bit of aluminium on it if that makes you cringe).

Laid the bike on its side, Marvel Mystery oil, let it soak overnight, tapped with a steel hammer and voila! Oh, two guys braced the frame with their feet while I hit it.
