After searching the web I found APP. Their FAQ helped understand the problem, their exploded view diagrams helped locate suspect or damaged parts. In my case I found that the Drive Blade was installed backwards from the factory. So over time ( 10 years) the blade dislodged from the Drum cracking it, and by freewheeling, it wore out the stop point on the Auger. After watching the how to videos,which were to the point, no fluff. In other words excellent. I Order the reasonably priced parts, which came promptly. In a short amount of time, I was doing my End Zone Dance. Thanks APP, you've just replaced 2 sites on my favorites bar.
