Gather Necessary Tools and Prepare the Mixer
Before beginning the repair, gather essential tools such as a Phillips and flat-head screwdriver, a soft cloth, and replacement seals or gaskets if needed. Make sure the mixer is unplugged and placed on a stable, flat surface. Wear gloves if desired to avoid oil contact or injury. Carefully remove the tilt-head lock and tilt the head back to access the internal components.
Disassemble the Mixer to Access the Gear Housing
- Remove the mixing bowl and attachments.
- Unscrew the screws securing the top cover of the gear housing, usually located at the back or underside, depending on your model.
- Gently lift the cover, noting the position of any internal parts or seals.
Inspect and Identify the Leak Source
Look for signs of oil leakage around the seals, gaskets, or the drive assembly. The most common cause is a worn or damaged seal inside the gear housing. Check for cracks, tears, or hardened rubber that may have deteriorated over time. If the oil appears to be coming from the drive shaft or gear assembly, these parts may also need inspection or replacement.
Replace Worn Seals or Gaskets
- Remove the old seals carefully using a flat-head screwdriver or a seal removal tool.
- Clean the area thoroughly with a soft cloth to remove any residual oil or debris.
- Install the new seals or gaskets, ensuring they are seated properly and flush with the housing.
Reassemble and Test the Mixer
Carefully reattach the gear housing cover and tighten all screws securely. Reinstall the tilt-head, bowl, and attachments. Plug in the mixer and run it at low and high speeds to check for any leaks. If oil continues to leak, double-check the installation of seals or look for additional damage.
