Layerneer

Thanks! I was able to pry it apart pretty easily with a small flat screw driver. Slipping the screw driver between the two halves, I was able to see the legs of the internal tabs. Then, I pressed in slightly on the legs with the screw driver while pulling it apart. 
 
Swapping to the old bushing sleeve and reassembling was pretty easy. The belt and spring stayed in position.
 
I attached pictures of the open one, and pictures of the faulty bushing. It has gouges and abrasions on both ends, and it skewed the shape of the opening.
 
Should be back up and running.
