Replacement Lower Auger Bearing forSerenity Pellet Stoves. The bottom bearing is located underneath the circular plate and is held in place by a snap ring (You will need needle-nose orsnap-ring pliers to fully remove this ring). When reassembling, ensure that the bearings are in place and do not bind up when the auger shaft is spun. The bearing should glide around freely with little resistance but should not whizz around like a skate wheel when spun.
