96 cutless supreme power steering pump pulley

The power steering pump pulley on my daughter's 96 cutless supreme. I went to the parts house and got a new one. I am wondering how to remove what's left of the old one. It appears to be held on with an allen screw. I don't know if it is right hand threads or left. Also, there are thread inside the shaft. If you have done this you will know what I'm talking about. Any help would be greatly appreciated.

answer to this is on the Silhouette the page
