Identifying the Source of the Oil Leak
- Begin by unplugging your mixer and placing it on a clean surface.
- Inspect the exterior, focusing on the gear housing, motor head, and around the shaft for oil residue or wet spots.
- Check if the oil is dripping from the bottom or seeping from the sides. The most common leak points are near the gear case or the drive shaft.
- Note any unusual buildup or signs of wear, which can help you determine whether the internal seals are failing.
- Remember, a small amount of lubrication is normal, but persistent or increasing oil indicates a leak needing repair.

Gathering Tools and Replacement Parts
- Gather a Phillips and flat-head screwdriver set for disassembling the mixer.
- Prepare replacement seals or gaskets compatible with your KitchenAid Artisan Series 5 Quart Tilt Head Mixer, which may be available from authorized parts suppliers.
- Have a clean cloth or rag, degreasing solution, and a small container for collecting oil during disassembly.
- If your model’s manual is available, review it for specific part numbers and disassembly instructions.
Disassembling the Mixer for Inspection and Repair
- Remove the pouring shield and tilt the head back to access the internal components.
- Unscrew the screws holding the gear case or cover, usually located near the top or side of the mixer.
- Carefully lift the cover to expose the internal gears, drive shaft, and seals.
- Inspect the seals or gaskets for cracks, wear, or tears. These are typically made of rubber or silicone and are designed to contain lubricants.
- Clean any residual oil and debris from the internal parts using a cloth and degreasing solution.
Replacing Faulty Seals or Gaskets
- Remove the old seals carefully, noting their orientation.
- Install the new seals, ensuring they fit snugly and are correctly aligned.
- Apply a small amount of food-grade or manufacturer-approved lubricant to the seals to help them seat properly and prevent future leaks.
- Reassemble the gear case or cover, tightening screws securely but not overly tight to avoid damaging the new seals.
Reassembling and Testing Your Mixer
Once all parts are securely in place, lower the mixer head back into position and reconnect any removed components.
Plug in your mixer and run it at low speed to check for leaks. Observe the area around the gear housing and drive shaft for any signs of oil seeping out.
If no leaks are present and the mixer runs smoothly, your repair is successful. If leaks persist, recheck the seal installation or consider consulting a professional repair service.
