Gather Your Tools and Prepare the Workspace
- Unplug the mixer from the power outlet to ensure safety during the repair process.
- Gather essential tools: a Phillips and flat-head screwdriver, a small socket wrench, a clean cloth, and replacement seals or gaskets if needed.
- Choose a clean, well-lit workspace with enough room to disassemble and reassemble your mixer.
- Wear safety gloves if you prefer to protect your hands from sharp edges or residual oil.
Disassemble the Mixer Carefully
- Remove the tilt-head lock lever and tilt the head back to access the internal components.
- Unscrew the top screws securing the motor housing and gently lift off the cover, exposing the internal gear mechanism.
- Take note of the placement of parts and screws, or better yet, photograph the disassembly for reference.
Identify the Source of the Oil Leak
Inspect the internal gear housing and surrounding seals for signs of damage or wear. Commonly, oil leaks occur when the internal seals or gaskets have deteriorated or cracked. Check for:
- Cracks or tears in seals or gaskets
- Excessive oil accumulation around the gear mechanism
- Oil seepage from the bottom or sides of the gear housing
Replace Faulty Seals or Gaskets
- Remove the damaged seals or gaskets carefully using a small flat-head screwdriver or tweezers.
- Clean the surrounding area thoroughly with a cloth to remove old grease and debris.
- Install the new seals or gaskets, ensuring they sit snugly in their designated positions.
- Apply a small amount of food-grade or appliance-safe lubricant if recommended by the manufacturer.
Reassemble and Test Your Mixer
- Carefully reattach the gear housing cover and tighten all screws securely.
- Reinstall the tilt-head and lock it into place.
- Plug in the mixer and run a test cycle with no ingredients to check for leaks.
- Observe carefully and ensure no oil seeps during operation.
