Product review (5 stars): Honey, I fixed the washer!
Washer literally ground to a halt one night.  Checked underneath and found the pump pulley wouldn't turn.  Ordered this based on other positive reviews.  It's not a carbon copy of the factory Maytag pump, but it bolted right in, the drain hose nipple was properly aligned and was the proper size, and the washer now runs quieter than I can remember.
