Product review (5 stars): Saved $$$ by getting this part instead of buying a new washing machine!
Our washing machine stopped agitating.  We figured we would need to buy a new machine for big $$.  My husband googled the problem and viewed some youtube videos to determine that the likely culprit was the pump drive coupler.  He took the machine apart in less than a half hour to confirm that the coupler was broken.  We were going to order this part through Sears for $20 with high shipping costs.  Then I did some research on Amazon & found the exact same part for a lot less (and free shipping).  The part arrived in a few days, and my husband fixed our washing machine in time for me to do our weekend laundry.
