I can't for the life of me figure out how to loosen the pulley for the ac belt. I've got a bolt that screws on, but don't seem to connect to anything other than a chunk of metal inside a nearly impossible to see compartment, to which I think connects to the pulley.


I've tried removing the screw, lightly hammering at the pulley to push it, hammering lightly at the screw while in, and using a screwdriver to wedge between the metal object inside and the mount, all of which result in nothing. Am I missing something here?
