I am even later to the game on this post but just got a SWA-2000 with the broken gear mentioned by others. Since that eBay link is no longer valid, would anyone be able to tell me more about the Kenmore replacement gear that you used? What model of Kenmore was it for? Is it called the zigzag gear or drive gear or ....?

The lobe is the same, as well as the thickness of the shaft and the distance between the lobe and the collar. The set screw still reaches the shaft and it works perfectly.
