Tip & How-To about KitchenAid K45SS Classic Stand Mixer
Is your KitchenAid mixer making loud grinding sounds and running slow? This is a common problem with these mixers. One or more of the screws holding the beater drive mounting plate in, has backed out, and is rubbing against the plate making a loud grinding sound and slowing the unit down.
The solution involves removing the beater driver shaft and plate and taking out all the mounting screws, then reinserting them with lock tite, available at Lowes or Home Depot in the hardware department.
The beater shaft, located vertically, has a pin in it which needs to be driven out with a punch and hammer. Then a "C" clip must be removed from the base of the shaft. You will need some "C" clip pliers available at any automotive parts store. Using the pliers insert them in the holes in the "C" clip ends and squeeze the handle. This will spread the "C" clip and allow you to slide it off the shaft.
Next pry the chrome bezel off around the exterior of the shaft which will expose about 6 screws which need to be taken out. These are the screws causing the problem. They should be removed one at a time and replaced with lock tite added to the threads.
Reassemble the mixer after all the screws have had lock tite added. This should quiet your unit and make it run faster.
