Harmonic Balancer Help, removal a/c and power steering

Hey everyone. I'm currently trying to disassemble my engine that has a double pulley for a/c, so the harmonic balancer is first. Tried removing it with a crow's foot puller, but so far nothing. No bolt in the middle. Am I missing something? Can they be pulled one at a time?

Also, when this is done, I want to add power steering too. Does this mean I need to find a triple wide pulley? Thanks!
