Why Greasing Your KitchenAid Mixer is Important
Your KitchenAid stand mixer is a powerhouse in the kitchen, capable of handling everything from delicate meringues to dense bread doughs. At the heart of this robust performance lies a complex system of gears and moving parts within the stand mixer gearbox. Over time and with consistent use, the original grease can dry out, break down, or become contaminated. This degradation leads to increased friction, heat, and wear on these critical components.
Neglecting to properly grease your KitchenAid mixer can result in a variety of problems:
- Increased noise: Dry gears grind against each other, producing an unpleasant whining or grinding sound.
- Reduced performance: Friction slows down the motor and attachments, making it harder for the mixer to perform its tasks.
- Overheating: Excessive friction generates heat, which can damage internal components and potentially lead to motor failure.
- Premature wear: Metal-on-metal contact without proper lubrication accelerates the wearing down of gears and other parts.
- Costly repairs: Ignoring these issues can escalate into serious damage, requiring expensive KitchenAid mixer repair grease or even full component replacement.
Regular lubrication is not just about preventing problems; it’s about optimizing the efficiency and longevity of your KitchenAid mixer. By providing the right type of grease to the right places, you ensure smooth operation, consistent power, and a longer lifespan for your valuable kitchen tool. This DIY KitchenAid mixer service is a rewarding way to keep your mixer running like new.
Deciphering the Components: What Needs Greasing?
When we talk about greasing a KitchenAid stand mixer, we’re primarily referring to the internal components within the mixer head and the stand mixer gearbox. These areas house the intricate network of gears that translate the motor’s power into the planetary action of the mixing bowl.
The main areas that require regular attention for KitchenAid mixer lubrication are:
- The Gearbox: This is the central hub where the motor’s rotation is converted and directed to the various mixer speeds. It contains a series of metal gears, worm gears, and shafts that mesh together. Proper lubrication here is crucial for smooth power transfer and preventing metal-on-metal contact.
- The Planetary Gear System: This system is responsible for the characteristic circular mixing motion that reaches all parts of the bowl. It involves a central drive gear that engages with satellite gears, which in turn drive the beater attachment. The KitchenAid mixer planetary grease ensures these gears rotate freely and efficiently.
- The Tilt-Head Mechanism (for tilt-head models): While not a direct part of the power transmission, the pivot point where the head tilts can benefit from a small amount of grease to prevent stiffness and ensure smooth operation when raising and lowering the head.
It’s important to note that not all parts of the mixer need grease. The motor itself is sealed and does not require lubrication. The exterior of the mixer also should not be greased. Our focus is on the internal mechanical components that are designed to be lubricated for optimal performance.
Choosing the Best Grease for Your KitchenAid Mixer
Selecting the appropriate grease is paramount for successful KitchenAid mixer lubrication. Using the wrong type of grease can be as detrimental as not greasing at all. You need a specialized grease that is designed for high-load, high-speed applications and is compatible with the metal alloys used in KitchenAid mixer gears.
The best grease for your KitchenAid mixer is typically a food-grade, high-temperature, synthetic lithium-based grease. Here’s why:
- Food-Grade: This is essential because the grease is inside a kitchen appliance, and there’s a potential for it to come into contact with food. Food-grade lubricants are non-toxic and safe for incidental food contact.
- High-Temperature Stability: Mixers generate heat during operation. The grease needs to maintain its consistency and lubricating properties at elevated temperatures without breaking down or becoming too thin.
- Lithium-Based: Lithium greases are known for their excellent water resistance, thermal stability, and load-carrying capabilities, making them ideal for the gears in a stand mixer.
- Synthetic: Synthetic greases generally offer superior performance over petroleum-based greases, including better temperature range, longer life, and improved resistance to oxidation and breakdown.
What to Avoid:
- Petroleum Jelly (Vaseline): While a lubricant, it’s not designed for the mechanical stresses and temperatures within a mixer. It can break down and attract dirt, causing more harm than good.
- WD-40 or similar penetrating oils: These are primarily designed for loosening rusted parts and displacing moisture. They evaporate quickly and do not provide long-lasting lubrication for gears.
- General Purpose Greases: Unless specifically rated for high-load gear applications and food-grade, avoid standard automotive or household greases.
Where to Find the Right Grease:
- Authorized Parts Retailers: Many appliance parts stores, both online and brick-and-mortar, will carry specific KitchenAid mixer repair grease or compatible food-grade gear lubricants.
- Online Retailers: Websites like Amazon, eBay, and specialized appliance parts websites are good sources. Look for terms like “KitchenAid mixer grease,” “stand mixer gearbox grease,” or “food-grade lithium grease.”
- DIY Appliance Repair Shops: Local shops that specialize in appliance repair may also sell the correct lubricants.
When purchasing, ensure the product description explicitly states it’s suitable for KitchenAid mixers or similar gearboxes. The amount of grease needed is usually quite small, so a small tube or tub should last for several service intervals.

Step 1: Prepare Your Workspace and Mixer
- Unplug the Mixer: Again, ensure the mixer is completely unplugged.
- Set Up Your Workspace: Lay down paper towels or a clean cloth on a stable surface. Have your tools and container for screws ready.
- Position the Mixer: Place the mixer in a comfortable working position, usually with the head tilted back or upright depending on the disassembly steps.
Step 2: Accessing the Gearbox
This is where model variations come into play. Generally, you’ll need to remove the base or cover that encloses the gearbox.
For many common KitchenAid Tilt-Head Models (e.g., Artisan, Classic, Ultra Power):
- Remove the Base Cover:
- Look for screws on the underside of the mixer base. These are often Phillips head screws.
- Some models might have clips that hold the base cover in place. You might need to gently pry the cover off once the screws are removed.
- Carefully lift the base cover away. You may need to maneuver it around the power cord.
For Bowl-Lift Models:
- The process for bowl-lift models can be more involved as the motor and gearbox are often housed differently. You may need to remove side panels or the entire housing. It’s highly recommended to find a specific tutorial for your bowl-lift model.
Step 3: Removing and Cleaning Internal Components
Once the main housing is open, you’ll see the gears and shafts.
- Identify the Gearbox Components: You’ll typically see a large metal or plastic housing containing several gears.
- Remove the Gearbox Housing (if necessary): Some mixers allow you to access the gears without removing the entire gearbox housing. Others require removing screws that hold the housing together.
- Carefully Remove Gears:
- Note the order and orientation of the gears as you remove them. Taking photos with your phone as you go can be incredibly helpful for reassembly.
- Be gentle. These are precision parts. Avoid forcing them off shafts. Some might slide off easily, while others might have retaining clips.
- You may need to remove a worm gear, a planetary gear carrier, and other associated gears.
- Clean Old Grease:
- Use paper towels or rags to wipe away all the old, dried-out, or dirty grease from the gears, shafts, and inside the gearbox housing.
- For stubborn, hardened grease, a plastic scraper or an old toothbrush can be useful. A small amount of isopropyl alcohol on a rag can help dissolve residue, but ensure it evaporates completely before re-greasing.
Step 4: Applying the New KitchenAid Mixer Planetary Grease
Now it’s time for the fresh lubrication.
- Apply Grease to Gears:
- Apply a moderate amount of the new grease to the teeth of each gear. You want to coat them thoroughly but avoid excessive amounts that could be flung off.
- Apply grease to the shafts where the gears sit to ensure smooth rotation.
- Grease the Planetary Gear System:
- Pay special attention to the planetary gear carrier and the satellite gears. Coat their teeth and where they mesh with the drive gear.
- The KitchenAid mixer planetary grease is critical here for smooth operation.
- Grease Other Moving Parts: If you removed any other components that have metal-on-metal contact (like the tilt-head pivot point on some models), apply a small dab of grease.
Step 5: Reassembly
This is where your photos and careful observation come in handy.
- Reinstall Gears:
- Working in reverse order of disassembly, carefully place the gears back onto their respective shafts and into the gearbox housing.
- Ensure they mesh correctly without grinding or forcing.
- Secure the Gearbox Housing: If you removed the gearbox housing, reattach it using the screws you removed.
- Reattach the Base Cover:
- Carefully position the base cover back onto the mixer. Ensure no wires are pinched.
- Reinstall all screws to secure the cover.
Step 6: Testing Your Work
- Plug In the Mixer: Once everything is reassembled, plug the mixer back into the power outlet.
- Test Speeds:
- Start the mixer on its lowest speed setting. Listen for any unusual noises.
- Gradually increase the speed, checking for smooth operation and responsiveness.
- The mixer should sound noticeably quieter and run more smoothly than before.
- Check the Tilt-Head (if applicable): Raise and lower the mixer head a few times to ensure it moves freely.
