5KSB45SWH0 KitchenAid Blender - Overview

I decided to see if I could dislodge the faulty coupling. I placed a screw driver under the coupling and pushed up. It dislodged. Subsequently I found a youtube video that indicated that was exactly what I should do.
I ordered the part from parts select and placed the coupling on my blender. It screws in counterclockwise. It works ... Read more fine. I am very satisfied.

Replaced the timer

to replace the coupling you take the bottom off the blender and loosen the screws that hold the bracket and fan -then comes the hard part-the shaft screw is bolted through every bit of the guts then into the coupling. It is a lefthand thread. I ended up having to fabricate a piece of metal that slipped into the top of the coupling (in the ... Read more teeth.) Then I secured the metal piece-it was just a twi inch piece of steel- in the vise, I held the blender and I got a big guy to attack the shaft bolt with a bunch of pressure and a straight screwdriver. It finally popped and I was able to unscrew the old coupling and replace it with the new. Reminds of when guys put on lug nuts and I have to try and get them off. But I saved at least $100.
