Product review (5 stars): Perfect for the DIYer.
Worked.  I have no experience in washer repair.  I was able to replace this part without any instruction.  Diagnosis was simple.  I knew what the old pump sounded like when it worked. The washer wouldn't drain and I stopped hearing the sound.  This replacement was exactly identical to the one that was in my machine.  Everything is back up and running.  For a $20 part and $0 labor, this is a win.
