• Worn or broken coupling can cause the impeller not to turn or reduced water flow
• Can produce grinding, clunking, or slipping noises when failing
• Failure symptoms often include no water circulation, weak spray, or unusual motor noise

• One coupling (quantity: 1)

• Disconnect power and water supply before beginning any repair
• Verify the motor and impeller shafts are undamaged before installing the new coupling
• Remove the pump/motor assembly to access and replace the coupling
• If the motor shaft or impeller is damaged, replace the affected component rather than relying on a new coupling
