The Shaft and Pinion Assembly is an OEM part for Whirlpool stand mixers. This assembly includes both the shaft and the pinion gear that work together to drive the mixing action. It is crucial for the smooth and efficient operation of the mixer, ensuring that the beaters or attachments rotate properly to mix ingredients thoroughly. Causes of a bad shaft and pinion assembly can include wear and tear from regular use, overloading the mixer, or a lack of lubrication.
