Product review (5 stars): Worked exactly as expected
I used this item to repair the ice maker on my Kenmore refrigerator.  The weld joints on my old coupling broke, such that the "wings" on the coupling would spin freely and therefore would not turn the ice auger when the motor engaged.

Shipping was efficient.

The only tricky part was getting the old coupling off.  I removed the motor assembly (4 screws and a power connector) and used two locking vice grips to hold the cylinder in place while unscrewing the coupling (tapping the second vice grips with a hammer).  Once that was off, installing the new one was a snap.  Watch the threads closely as (it's been a couple of weeks) I think it unscrews clockwise, the opposite of normal screws.  The new coupling appears to be made better than the one that came with the refrigerator originally.  My automatic ice maker dispenser works again!
