Hello, I'm new to working on bikes and trying to convert a bike to electric. Trying to remove the crank and I've already removed the bolts that secure it, but now I see this. It seems like there is nothing for the tool to pull from. Anyone know what I can do to take this off?

Park tool CCP-4. This is an ISIS crank / BB
Time to commit a crime! An replacement for the isis/octalink plunger is apperently a (or better two) peace of US coinage, wich often is defaced in the process. Any metall disc/washer of the right size can be used also.
