Disassemble the Mixer to Access the Gear Housing
- Remove the tilt-head lock and tilt the head back fully.
- Unscrew the top screws holding the outer cover of the gear housing using a Phillips screwdriver.
- Carefully lift off the cover to expose the internal gear assembly and seals.
Inspect and Identify the Leak Source
Check the seals and internal gears for signs of damage or wear. Oil leaking from the gear housing typically indicates a worn or damaged seal or gasket. If you see oil around the seal or coming from the gear area, it likely needs replacement.
Replace the Seal and Reassemble
- Remove the old seal carefully, taking note of its placement.
- Apply a small amount of food-grade lubricant or grease recommended for kitchen appliances to the new seal.
- Insert the new seal firmly into its position, ensuring it sits flush.
- Reattach the gear housing cover and screw it back in place securely.
Test and Prevent Future Leaks
Plug the mixer back in and run it at low speed to check for leaks. If no oil escapes, gradually increase speed and observe. Regularly cleaning and inspecting seals can prevent future issues. Keep the mixer in a dry, clean environment to avoid dirt buildup that may wear seals faster.
