How to remove crank bolt up front?

[Beanhead]

UPDATE!

I managed to get the crankbolt out. Wasn't as tough as I thought using a breaker bar, and putting her in gear so the crank doesn't turn (thanks 5.slow, thought never crossed my mind). HOWEVER, then I go to pull out the balancer (or more accurately, whats left of it), using the proper puller, and that mofo will NOT budge! I'm pulling with all my might using a nice thick 2 foot breaker bar, and the damn thing will NOT slide out!!! I swear I'm going to pull her right up over the wheel chocks! This is like 10X more difficult than the crank bolt! So, I soaked the thing in penetrant a couple of times, and I'm going to leave it overnight and try again tomorrow. She just doesn't wanna give it up!
