remove old bearing from tensioner
 

Okay, this seems like it should be straightforward, but how do I remove the old busted bearing from the pulley and put on the new one? I turn the nut counterclockwise to remove tension, so do I turn the nut clockwise to release it and allow me to change out the bearing? If so, I'm gonna need a hammer.
Thanks
This is a 1994 Silhouette 3.8L.

On my chevy pick up the bolt holding the pulley to the tensonier is a left handed thred bolt (clockwise to loosen). I used a impact to loosen it.

Thanks. I needed a lot of force, but since you confirmed it was threaded righty-loosey, I was not afraid.
