Step 1: Unplug and Prepare Your Workspace

  1. Always unplug your KitchenAid mixer before starting any repair to prevent electrical shock.
  2. Place the mixer on a clean, flat surface with ample lighting.
  3. Gather necessary tools: Phillips and flat-head screwdrivers, a small wrench, and a clean cloth.
  4. Wear gloves if desired, to keep parts clean and prevent injuries.

Step 2: Access the Gear Housing and Internal Components

  1. Remove the attachment hub cover and the pouring shield.
  2. Using a screwdriver, unscrew the screws holding the top cover or the gear housing—consult your specific model’s manual for exact locations.
  3. Carefully lift the cover to expose the internal gears and seals.
  4. Note the position of all parts for correct reassembly.

Step 3: Identify the Source of the Oil Leak

  • Look for signs of worn or damaged seals, especially around the gear housing and shaft areas.
  • Check for excessive oil residue or drips near the motor or gear assembly.
  • Inspect the seals; if they appear cracked, hardened, or missing, they are likely the cause.

Step 4: Replace Worn or Damaged Seals

  1. Remove the damaged seals using a small flat-head screwdriver or a seal removal tool.
  2. Clean the surrounding area thoroughly with a cloth to remove old oil and debris.
  3. Install new seals, ensuring they sit flush and snug in their grooves.
  4. Reassemble the gear housing carefully, securing all screws tightly.

Step 5: Reassemble and Test Your Mixer

  1. Replace the top cover and any other parts removed, tightening all screws securely.
  2. Plug in the mixer and run it at low speed to check for leaks.
  3. Observe the gear housing and motor area for any signs of oil seepage during operation.
  4. If no leaks are present, gradually increase speed and test with typical mixing tasks.

Tips and Warnings for Safe and Effective Repair

  • Always unplug your mixer before starting repairs to avoid electrical hazards.
  • Work in a clean, organized space to prevent losing small parts.
  • Use the correct size tools to avoid damaging screws or components.
  • If you’re unsure about disassembly or replacing seals, consult a professional or contact KitchenAid customer service.
  • Do not operate the mixer if oil leaks persist after repair; it could damage internal parts or pose safety risks.
