W11200218 KitchenAid Stand Mixer Gear Grease – The genuine OEM food-grade lubricant for servicing the gear case on all KitchenAid and Whirlpool stand mixers. Essential for a mixer that makes grinding, growling, or knocking noises during operation, runs rough or vibrates excessively, has stiff or sluggish gears, leaks dark or discolored grease from the gear case, or needs a complete gear case lubrication service after years of use. The gear case contains the worm gear, worm follower gear, and planetary gears that transfer motor power to the beater shaft and attachment hub under high torque loads. These metal gears require proper lubrication to reduce friction, prevent wear, dissipate heat, and protect against corrosion. Over years of use, the original factory grease breaks down — it dries out, separates, or becomes contaminated with fine metal particles from normal gear wear. Deteriorated grease causes increased friction, heat buildup, louder operation, and accelerated gear wear that can lead to stripped or cracked gear teeth. This genuine OEM grease is NSF H1 registered and USDA approved for incidental food contact — safe for use in a kitchen appliance that processes food. Do not use automotive or general-purpose grease. One 4 oz tube is sufficient for a complete gear case regreasing. Directly replaces 4176597, W10112253, and WP4176597. Fits all KitchenAid and Whirlpool stand mixers including Artisan, Classic, Professional, Pro Line, and Commercial series.
