How do I replace blender rubber clutch for Kitchen Aid blender

SOURCE: Kitchen Aid Blender Rubber Coupling replacement

Someone else suggested a link that explains exactly how to unthread the old coupling... and it works. It took me about 90 seconds to fix my blender. But in case that link is dead, here's a summary:

(1) Note that the coupling (the round part with teeth) is threaded to the blender motor in reverse to a standard threading. So it screws off just like a bottle top, but in a clockwise direction.

(2) place the blender base on a tabletop, facing you. You should probably unplug it.

(3) take a punch or a flathead screwdriver, and place it against one of the coupling teeth that is furtherest away from you.

(4) strike the back of the screwdriver with a small hammer or maillot. The result will spin coupling clockwise. It may take several tries, but the coupling will eventually spin clockwise faster than the motor, and it will begin to unthread.

(5) unscrew the old coupling, and screw the new coupling into place (counterclockwise). Note that the new coupling will tighten itself every time you use your blender, so no need to worry about tightening it too much.

(6) Make a smoothie to celebrate your success!

The piece that you need is referred to as the coupler. The coupler is a breakway part that is designed to shear and/or wear down in the event that the blender is overloaded. This is to avoid damage to the motor.

The coupler may be purchased individually and is an easy repair that can be done at home. You may purchase the part and access step-by-step replacement instructions at the following link:
