Contractor 10 Pack of washing machine motor couplings. The center of this coupling does have the metal for a stronger grip. Does require taking the machine motor off as the coupler sits between the motor and transmission. If this coupler is constantly breaking then most likely you'll need to replace additional parts to keep from happening again such as the clutch, motor, and/or transmission.
