Whirlpool Washer Agitator Clutch Dog 3366877 – Superseded by 80040

OEM kit containing four plastic agitator directional cogs, also called agitator dogs or dog ears. The cogs allow the upper agitator to rotate in one direction while preventing reverse rotation; commonly used in direct-drive top-load washers.

Is This the Right Part?

Common Symptoms

• Washer agitates poorly or will not agitate effectively.
• Upper agitator spins freely in both directions.
• Clothes receive reduced wash action because the upper agitator is not ratcheting.
• Agitator may move intermittently or slip under load.

Check Before Replacing

• With the washer unplugged and empty, gently check whether the upper agitator rotates freely in both directions; excessive free rotation can indicate worn directional cogs, but this check is not conclusive.
• Observe whether the lower agitator moves while the upper portion fails to engage during a normal cycle; do not place hands in the washer while it is operating.
• Inspect the accessible cogs for visibly worn, cracked, or missing teeth only after following the model-specific procedure for removing the agitator.
• Confirm that the installed agitator design and model-specific parts list call for the 80040 cog set before ordering.
