Question 06 WRX Crank Pulley & Belts

Needs some help here.

Some time last week my AC belt got ripped up by the idler pulley. So since the belt went I replaced it with a new one including the pulley. Now last night my new belt ripped again. Here some photos.

When I installed the new belt and pulley the crank pulley wasn't sucked in like the photos above. It was pulled all the way out and every thing was lined up. So my question is. Is the crank pulley supposed to do that? To move back and forth? Because when it moves all the way like in the photo the ac belt rubs on the TBC and just brakes off. And also puts the psp & alt belt off line also.

Any thoughts/suggestions?

Looks like the crank pulley has separated where the rubber was bonded to the inner part of the pulley and allowed the outer 1/2 to walk back towards the engine.
