ok with my mechanical design engineer (yes i am degree qual'd) hat on - gears don't squeak, not never!! not al all, bearings do squeak however. ok now with my beekeepers hat on my spinner also had a squeak. it was the bottom bearing. I pulled the cage out, cleaned the bearing, used food grade grease and boom all good, well kind of, all it does now is vibrate and walk across the floor. at least its quiet. lolWe have a little 2 frame extractor that's squeaking .. The gears are enclosed [remove plate to view gears] - what do people [with little manual extractors] use to lubricate the gears ?
