Hello These auger bearings were dry! See dry channel in pics below. Pellet stove is 2009 and auger and bearings were never removed until now! Here we pump Red High temp grease from a cartridge into the alemite fitting using a grease gun purchased from Lowes or Home Depot. How often do you apply the red stuff.
