No the turntable shaft. The coupler fits into the shaft. I have already ordered the shaft part # XXXXX or #40 on the kitchenaid parts schematic.
No, It is called the turntable shaft. Part select Canada has it labeled as part #40 as well. It is not the drive coupler. It would go on top of the drive coupler.
I already have the parts installation schematic for the turntable shaft. Thanks for your effort, but I was hoping there were some step by step directions, or the most appropriate means to access it.
