The lift arm inside a KitchenAid stand mixer’s pedestal raises and lowers the bowl during operation. Over time, it may wear out or stop functioning properly. Fortunately, replacing it is a quick and straightforward process.
Common Signs of a Faulty Lift Arm
The lift arm can wear out over time. Here are some signs that indicate it may need replacement:
- The mixing bowl does not lift or lower properly.
- The arm feels loose or wobbly when in use.
- Unusual grinding or clicking sounds when adjusting the bowl height.
- The bowl does not stay in position while mixing.
- The arm is visibly bent, rusted, or damaged.
- The lift mechanism moves inconsistently or gets stuck.
If any of these issues appear, replacing the lift arm can restore proper function to the stand mixer.
Check Part Compatibility
Before starting the replacement, make sure you have the correct OEM lift arm for your specific mixer model. To find the model number:
- Look for a sticker or metal plate labeled “MOD” or “Model.”
- Common locations include:
- The underside of the mixer’s base
- The back of the motor housing
- The side of the mixer’s base
Write down the model number or take a photo for reference when purchasing the replacement part.
Gather Your Tools
You’ll need the following:
- Large Phillips ratchet
- Flathead screwdriver
- Needle nose pliers
- Roll pin punch
- Hammer or mallet
- Wood (optional, for added stability)
- Towels (optional, to protect surfaces)
- Replacement lift arm
Safety First
Working on any appliance requires caution. Follow these safety guidelines:
- Unplug the mixer or turn off the circuit breaker to prevent electric shock.
- If the mixer was recently used, allow it to cool completely.
- Work in a well-lit, clutter-free space to keep everything accessible.
- Keep children and pets away from the area.
- Never handle internal parts with wet hands—make sure your workspace is dry.
- Check the user manual for any model-specific instructions.
- Use gentle pressure when removing or installing parts to avoid damage.
- If working near wiring, avoid touching exposed wires. Use non-conductive tools or insulating gloves when necessary.
How to Replace the Lift Arm on a KitchenAid Stand Mixer
Here are the steps to remove the old lift arm and install a new one to keep your mixer working properly.
Removing the Old Lift Arm
- Remove the beater by lifting it and turning it clockwise until it lifts out. Set it aside.
- Lift the bowl and pull it out of the mixer.
- Place a towel or a piece of wood on each side of the mixer to stabilize it when flipping it upside down.
- Turn the mixer upside down, holding the base securely.
- Use a Phillips screwdriver to loosen and remove the four screws holding the two halves of the mixer together. Be careful not to strip the screws.
- If the base is stuck, gently rock it back and forth to loosen it.
- Lift the base off and set it aside.
- Move the lift arm into the up position.
- Use a screwdriver to straighten the cotter pin, then use needle-nose pliers to pull it out. Set the cotter pin aside.
- Slide the rod out of the lift arm.
- Lower the lift arm to the down position and release it.
- Use a roll pin punch to drive out the roll pin from the bottom of the mixer.
- Lift the base and remove the roll pin, then set it aside.
- Partially pull out the lift arm until it is fully detached.
Installing the New Lift Arm
- Align the new lift arm in the down position with the roll pinhole on the side.
- Hold the arm in place and push the rod through it.
- Align the hole in the arm with the roll pinhole.
- Use a roll pin punch and a hammer to insert the roll pin through the aligned holes.
- Lift the bowl support arm to raise the linkage and insert it into the lift arm.
- Use a screwdriver to guide the arm upward so it does not get caught on anything.
- Move the lift arm into the up position.
- Rotate the arm upward and guide the linkage into place.
- Lift the arm to the lock position and insert the cotter pin.
- Bend the arms of the cotter pin to lock it in place.
Reassembling the Mixer
- Move the lift arm to the down position.
- Align the two halves of the mixer, making sure the locating pins on the base fit into the receptacles on the mixer head.
- Lift the base and align the pins before joining the two halves together.
- Place the Phillips screws back in and use a wrench with the screwdriver to tighten them securely.
Final Assembly and Testing
- Align the pinholes on the bowl and set it down, then lock it in place.
- Align the beater shaft with the opening, making sure the locking pin goes into the slot.
- Lift the beater into place and lock it on.
- Plug the mixer back in and turn it on to check that the lift arm functions properly.

Maintaining Your Mixer After Replacement
Once the new lift arm is installed, regular maintenance can help keep the mixer working efficiently:
- Lubricate moving parts: Periodically apply food-safe grease to the lift mechanism to prevent wear.
- Clean after each use: Wipe the pedestal and lift mechanism to remove any batter or residue buildup.
- Check for loose parts: Inspect screws, pins, and hinges regularly to avoid unexpected failures.
- Avoid overloading: Mixing heavy doughs frequently can strain the lift arm, leading to premature wear.
- Store properly: When not in use, cover the mixer to keep dust and debris out of the moving parts.
