Brand new KitchenAid rubber blender coupler and removal tool.Fits models: KSB3 and KSB5Below are the instructions for repairing the coupler/clutch/coupling on the KitchenAid blenders:The blender's rubber coupling is designed to break if the blender is under strain.  This will often happen if the food being chopped is too hard or being chopped at too higher speed. The part failing prevents the motor from more severe damage.The coupler/clutch has six rubber teeth which grip the underside of the blade in the blending jug. The clutch is secured to the blender spindle (which is made of steel) with a reverse aluminum thread. i.e. you turn clockwise to undo it which is the opposite to normal.There are two ways to remove the old clutch.
