Disconnect the battery and remove the fan assembly and crankshaft belts. Remove the center bolt from the pulley and use a crankshaft pulley remover to pull off the pulley. You can usually borrow one from an auto parts store.

The pulley alone unbolts from the harmonic balancer (aka vibration damper). It's the harmonic balancer that requires a special puller to remove it from the crankshaft without doing any damage.
