Customer Questions and Answers for Pinion Gear (Drive) by Whirlpool

This small drive gear transfers motor power to the rest of the gear train. Replacing a worn or stripped pinion restores smooth, consistent rotation and helps prevent additional damage to neighboring gears and shafts. What it does:

• Engages the mating gear to transmit torque from the motor
• Drives the output gear train for consistent movement
• Maintains proper gear mesh inside the drive housing
• Typical failure signs: grinding/clicking, slipping under load, or no movement of driven parts

• 1 pinion gear

• Disconnect power before servicing; allow all moving parts to stop
• Access the gearcase/drive housing and note the original gear's orientation
• Inspect mating gears; replace as needed and use manufacturer-approved grease if required
• Hand-rotate the assembly to verify smooth operation before reassembly and test
