So the crankshaft pulley is not turning essentially? The crankshaft turns, the pulley does not?

thank you for your response daveJHM. my answer to your question is yes and yes.

its like there are 2 rotating pulley cascade together. the internal pulley rotates but the external pulley does not. thats how i can best describe it by looking at the engine while it is in idle.

If I am not misaken, it's the pulley itself that requires replacement. It should be a dampner assembly - that is, connected by rubber to dampen engine vibration. The rubber may have torn, causing the pulley separation.

Pretty much, but I would probably defer to a dealer part, just for overall part quality, longevity and fitment for something like that.
