coupling on blender dry rotted

simply hold the axel with the wire stripper to prevent from rotating. Using the pliers firmly turn old coupling counterclockwise until loose. Once this coupling is totally off you are ready to screw on the new one. Very simple. The most difficult part was finding a tool slim enough to fit between old coupling and base to hold axel from spinning. I ordered part on sunday and received it on tuesday. It spared me from throwing away a $120.00 dollar kitchenaide blender.
