Nylon Drive Gear
The drive gear is a sacrificial nylon component designed to strip or allow the clutch to slip when the burrs are immobilized. A persistent clicking sound indicates that the teeth on this gear have been sheared or deformed due to a high-torque event, such as a rock or heavily compacted 'fines' preventing rotation. Replacing this gear restores the mechanical link between the motor and the burr assembly.

Upper Burr Assembly
If the upper burr is not seated perfectly or the wire retaining clip is loose, the burr can tilt under load, causing a mechanical misalignment. This misalignment increases rotational resistance and triggers the torque limiter's clicking sound. Replacing the assembly ensures the burrs meet at the correct parallel geometry.

Stainless Steel Impeller
The impeller sits beneath the lower burr and is responsible for sweeping ground coffee into the exit chute. If the impeller blades are damaged or caked with oily residue, grounds back up into the burr chamber, creating a 'fluid lock' of compressed coffee that stalls the motor and forces the clutch to click.
