Accessing the Gear Area
To inspect the internal gear assembly, you need to remove the attachment hub cover and the gear cover. Use a Phillips screwdriver to unscrew the screws holding these covers in place. Carefully lift the covers away, noting their position for reassembly.
In my testing, this step requires patience; ensure you keep track of all screws and small parts. If you see any debris or buildup inside, it could contribute to the grinding noise.
Inspecting and Cleaning Components
- Check the gears for visible wear, chips, or broken teeth. Worn gears often cause grinding sounds when they fail to mesh properly.
- Clean all parts with a dry cloth or a brush to remove dust, debris, or old lubricant that could be causing the noise.
- If gears are dirty or sticky, apply a food-grade silicone lubricant sparingly to ensure smooth operation. Do not over-lubricate, as excess can attract dirt.
Replacing Worn or Damaged Gears
If you discover cracked or chipped gears, they should be replaced. Ensure you purchase compatible replacement gears designed for your model. Consult the user manual or contact KitchenAid support for the correct part numbers.
To replace, remove the damaged gear by gently prying it off the gear shaft. Install the new gear in the reverse order, ensuring it meshes correctly with adjacent gears.
Reassembling and Testing
- Replace all covers and screws securely.
- Plug in your mixer and run it at a low speed to check if the grinding noise persists.
- Gradually increase to higher speeds to ensure smooth operation without abnormal sounds.
If the noise continues despite these steps, further inspection may be needed, or professional repair might be required.
