how to remove crankshaft pulley

Pulley bolts to the dampner (harmonic Balancer). The dampner might need a puller to get it off the crank, but you say you have it off, unless you miss-typed and you really have the pulley off, and need to get the dampner off the crank. You can buy a cheap puller at the parts store for about $15. Don't try to beat it off with a hammer.
