WP2IIT/IIIPYROB93 Pellet Stove. Auger is making noise and I can move the entire unit (removed back lower plate) by hand. Need diagram of auger assembly. Motor is good and auger turns, but it has an inch or so of play. I can move the entire assembly in and out about an inch. Still works but making a scraping noise. Do you have a diagram of the entire auger assembly for this unit so I can see what is wrong/loose. All the bolts seem tight and secure.
