crank pulley bolt

impossible.......
ive broken 3 ratchets. i have a huge breaker bar. we tried 3 different impact guns all the way up to 600ft/lbs. i snapped part of the pulley off tryingto shove something betwwen it nd the block. i did the screwdriver in tranny thing but it wont hold.
plus i have the jdm d15b and the pulley it has is open in the center so i cant use that hex key tool thing.
sssoooooooooooo wht do i do?
