pressed in blower pulley

[cobra-k]

I am chasing an alignment issue still and a few people have brought up that my blower pulley looks pressed in too far? My question is how can the blower pulley be pressed in to far? how does it happen?

Is it an aluminum pulley only? In other words, it has no steel hub.
