With the 4 bolts removed from the pulley it should come off....

The large bolt is the bolt that holds the harmonic balancer to the crank.

The big bolt holds the harmonic balancer on the crankshaft; the 4 bolts hold the belt pulley on the balancer. As stated above, remove the 4 bolts, and tap the pulley with a rubber mallet. It should come right off.
