I initially thought I would have to throw the entire appliance away because I had no idea as to how to get the broken coupling off the blender. I thought that the internet might have an answer, so I enterred the words: "KitchenAid Blender Parts". I got to the brand website and by entering the model number and further searching I was taken to the appropriate page. To my surprise, there was a 90 seconds video discribing how to remove the broken coupling, as well as having the new coupling available to order. It arrived at my home the very next day from UPS. I removed the broken coupling by just prying it out with a straight-edge screwdriver as directed in the video. I hade to remove a few pieces of metal that were stripped off the screw portion of the old coupling as it was pryed off the drive. I put the new coupling on the drive and only turned it to finger-tight. The reverse screw direction ensures the coupling is always turning to the tightening direction when the blender is working. The entire operation took only a couple of minutes after receiving the coupling. The website video was a super plus by having easy directions on how to change parts.
