Steven C Gig Harbor , WA June 30, 2020 Appliance: Model KITCHENAID KSB5BU3 Due to age the fingers on the coupling sheared off I replaced the coupling with a new coupling. To loosen the coupling I used a screw driver and a hammer to drive the coupling in the clockwise direction. After a couple of hard raps, the old coupling spun off.
