Kitchenaid Mixer Gearcase Parts

Restore your stand mixer's drive system with this gearcase. It serves as the transmission, routing motor power to the planetary while enclosing and supporting the gears for smooth, consistent mixing performance. What it does:

• Directs motor power through the gear train to the planetary/attachment hub
• Encloses, supports, and aligns the gears; retains transmission grease
• Helps address grinding/rumbling, grease leaking from the mixer head, weak or stalled planetary, or excessive vibration

• 1 gearcase

• Unplug the mixer; remove bowl and attachments; protect the work area from grease
• Remove the motor head cover and fasteners; separate the case and note gear stack orientation
• Transfer gears/seals as needed and repack with food-grade grease if servicing the gear train
• Reassemble, tightening screws evenly; test at low speed before normal use

This gearcase is the main transmission assembly that transfers motor torque to the washer's tub and agitator, restoring normal agitation and spin performance when the original gearcase fails. What it does

• Converts motor rotation into the gear reductions needed for agitation and spin cycles.
• Commonly replaced for symptoms like no agitation, slow or failed spin, grinding or clunking noises during cycles.
• Contains internal gears and bearings that can wear or break, causing irregular movement or loss of drive.
• Works with the washer's motor coupling and drive components to re-establish reliable drum motion.

• One gearcase (transmission) assembly.

• Disconnect power and water supply before beginning any repair.
• Support the washer cabinet and tub when removing the old gearcase to avoid damage or injury.
• Gearcase assemblies are heavy and contain grease—expect some lubricant exposure; clean hands and work surfaces after installation.
• Use model-specific service manual or exploded parts diagram for proper alignment and reassembly; replacement may require transfer of seals or mounting hardware.
