Step 1: Unplug and Prepare Your Mixer
- Ensure the mixer is unplugged from the power outlet and has cooled down completely.
- Place a towel or cloth beneath the mixer to catch any small parts or residual oil.
- Gather your tools: a screwdriver set, replacement seals (if available), and cleaning supplies.
Step 2: Remove the Mixer Cover and Access the Gearbox
Using a Phillips or flathead screwdriver, carefully remove the screws holding the top or side cover of the mixer’s gear housing. For the KitchenAid Artisan Series 5 Quart Tilt Head, tilt the head back and locate the screws securing the top cover. Carefully lift the cover to expose the internal gearbox and drive assembly.
Be cautious to avoid damaging any wiring or internal components. Keep track of screws and small parts for reassembly.
Step 3: Inspect for Worn Seals or Excess Oil
- Look for visible oil leaks around the seals, gears, and the base of the gearbox.
- If you notice old, hardened, or cracked seals, they are likely the cause of the leak.
- Check the oil level inside the gearbox—if it appears overfilled or contaminated, it may need draining or replacing.
Step 4: Replace Worn Seals and Reassemble
If seals are damaged, remove the old seal carefully using a flat-head screwdriver or seal removal tool. Insert the new genuine KitchenAid seal, ensuring it fits snugly into place. Be sure to lubricate the seal with a bit of food-grade oil if recommended by the manufacturer.
Once replaced, reassemble the cover and tighten all screws securely. Double-check that everything is aligned properly before moving on.
Step 5: Test the Mixer and Clean Up
Plug the mixer back in and run it at low and high speeds to ensure the leak has stopped. Observe for any signs of oil seepage. If the problem persists, recheck the seals or consider replacing internal gears.
Clean any spilled oil around the mixer with a damp cloth. Regularly inspect and maintain your mixer to prevent future leaks.
