hi, well, seems like another culprit has crept up to annoy me. when the feed drive kicks on, there is a thumping noise coming from the back of the stove. upon removing the back cover, voila! the auger gear drive is bouncing when the thumping noise appears. by placing my finger on the auger shaft and another finger on the gear drive, the gear drive seems to be the one jumping about(but that could be because of the rubber isolating mounts which gives in to the movement first). anyways, could it be my gear drive is on it's way out? can i dismantle it and fill with grease and inspect for wear. i might need a good source to order from, any suggestions? thx and stay warm.
