Question: replacing power steering pump

I'm replacing the power steering pump and am having trouble. Can I remove the pulley first, to get at the bolt above the pulley? I can't find a way to loosen the bolt above the pulley to even take the belt off? I think I can handle the rest of the project once I get started. Please help!
