1. Why is My KitchenAid Leaking Oil?

1. Why is My KitchenAid Leaking Oil?

KitchenAid mixers use a solid food-grade grease inside the gear housing. Over time, or with heavy use (like kneading stiff bread dough), the grease separates.

  1. The liquid oil separates from the thickener and pools at the bottom of the gear housing, eventually dripping out of the planetary ring onto your food.
  2. This is not a broken seal; it just means the mixer needs to be opened, cleaned, and regreased.

2. Removing the Motor Housing

Unplug the mixer. Remove the rear cover plate (one screw).

  1. Remove the silver planetary drip ring. It is friction-fit; use a flathead screwdriver covered in a towel to gently tap it down and off.
  2. Punch out the small metal pin holding the planetary gear shaft in place. Note: the pin is tapered, so it only pushes out one way.

3. Cleaning Out the Old Separated Grease

With the top gear housing removed, you will see a massive pile of brown/black grease covering the gears.

  1. Use a plastic putty knife and paper towels to scoop out as much old grease as possible. It is incredibly sticky.
  2. Carefully inspect the plastic 'sacrificial' worm gear visually. If it is stripped or missing teeth, replace it now while the machine is open.

4. Repacking the Food-Grade Grease

You must use specific Food Grade NSF H-1 grease (like Benalene or Super Lube) intended for Stand Mixers.

  1. Pack about 4 ounces of the new grease directly onto and around the gear clusters. Do not overpack, or the motor will struggle to turn.
  2. Reassemble the housing, tap the planetary pin back in securely, and tap the silver drip ring back into place using a rubber mallet.
