The 285753A coupler replaces what would of been your washer belt. Used on most Whirlpool/Kenmore older direct drive models, this coupler is inexpensive and easy to replace. Common symptoms are the washer goes into spin cycle but does not spin however you can hear the motor running or making a loud noise but not spinning then this is likely the part that has failed. These couplers typically last about 5 years depending on use.
