Product review (1 stars): Piece of junk.  To NOT buy, possible design flaw!
I bought this pump to replaced a pump on my Maytag washer that has lasted 10 years before screeching only to have this pump to the exact same thing after 2 months.  Now I have to mail it back for a refund at my expense.  What a total joke.  There is a metal collar that fits down inside the pulley presumably to keep the bearing held in place.  It works it's way up when spinning and then grinds into the bottom of the black metal housing around the plastic pump.  If this goes on too long, it can burn through the metal and then into the plastic pump thus creating a huge mess by leaking water everywhere.  It is also a fire hazard.  Another smart reviewer said to remove this metal collar but I cannot speak to that as I have not done it.

It seems to me that they would implement some type of cover to lock that metal collar into place.  They should fire the idiot that designed this pump.  What a waste of time and money.
