Understanding the Causes of Oil Leaking in Your KitchenAid Mixer
Oil leaks in your KitchenAid Artisan Series 5 Quart Tilt Head Stand Mixer are usually caused by worn or damaged internal components. The most common culprit is the oil seal, which prevents lubricants from escaping the gearbox. Over time, the seal can degrade due to age, heat, or improper use.
Other potential causes include overfilled gearboxes, use of incompatible lubricants, or internal damage from mishandling or overloading the mixer. Identifying the exact source of the leak is essential before proceeding with repairs.

Step 1: Unplug and Prepare Your Mixer
- Ensure your mixer is unplugged from the power outlet to prevent electrical shock or accidental activation.
- Place your mixer on a clean, flat surface in a well-lit area for easy access.
- Wear gloves if desired to protect your hands from any residual oil or grease.
Step 2: Access the Gearbox and Identify the Leak
- Remove the attachment hub cover by gently unscrewing it with a screwdriver or by hand if it’s loosened.
- Carefully tilt the mixer head back to expose the gearbox area underneath the tilt mechanism.
- Inspect the gearbox for signs of oil leakage, such as oil on the outside, oil pooling, or a greasy residue.
Step 3: Disassemble the Mixer for Seal Replacement
- Using the appropriate screwdriver, remove the screws securing the gear cover or gearbox housing.
- Gently lift off the cover, taking care not to damage any internal parts.
- Identify the oil seal — it is typically a rubber or silicone ring that fits around the gear shaft.
Step 4: Replace the Damaged Oil Seal
- Remove the old oil seal using a seal removal tool or a small flathead screwdriver, carefully prying it out without damaging the housing.
- Clean the area thoroughly with a lint-free cloth and isopropyl alcohol to remove old lubricant and debris.
- Install the new oil seal, ensuring it is seated evenly and flush with the housing surface.
Step 5: Reassemble and Test Your Mixer
- Replace the gearbox cover and secure it with screws.
- Reattach the attachment hub cover tightly.
- Plug in your mixer and run it at low and high speeds to check for leaks.
- Observe the gearbox during operation to ensure the leak has stopped.
Tips and Warnings for Safe and Effective Repairs
- Always unplug your mixer before disassembly to avoid electric shocks.
- Use genuine replacement parts for best fit and durability.
- Do not over-tighten screws, as this can damage the housing or seals.
- If you’re unsure about disassembling the mixer, consult a professional technician.
- Perform routine maintenance to prevent future leaks, including checking seals and lubricants periodically.
