My 6th year with my Ecoteck Elena......today I hear a bearing squeal.......auger motor sounds bad.....Took about 10 minutes to remove the motor.....4mm allen key on the shaft coupling....ran it on the bench with 110VAC...motor bearings are squeeling......a few drops of Mobil 1 0W-40 and it's as good as new. My spare auger motor can stay in its box.
