Mixer began to make a noise on speed two and higher
We took our 30 plus year mixer apart. I removed the old grease. There was some crumbly looking grease in the main housing gear section where the nylon gear is located. It looked like it had flour mixed in it. Not certain. Removed as best possible all old grease and applied 6 oz. of new Benalene grease to all of the gears. Now it do es not make the slight howl sound.
