Answer
 Hello Keith:

 If I am Looking at the Correct Breakdown and The Model Numbers Do Match the Breakdown; So here goes. You have Removed the Horizontal Auger. Then you Removed the Impeller. The Next Item on the Shaft Behind the Impeller is the Friction Drive Disc, then 2 Pulleys. If this is Correct, you need the Friction Wheel Disc Assy (Part No. 656-0012A). Hope this Helps. I am here if you Require more Assistance. Thanks.

 Good Luck

 Respectfully
