Product review (5 stars): Excellent Product--Great Buy
I called a appliance service place and was quoted a price of around $300 to replace this pump and another $200 to replace the belt. The washer quit working and leaked water on the floor. I went on the Internet and learned it could be this pump causing all of the problems. After further research, I found this drain pump could be used instead of the original model pump.

Replaced a water pump original number of 131724000 for a Kenmore stack washer/dryer combo model number 417.99812990

This pump worked perfectly and maybe even better than the original. It also fits the mounting area perfectly.  It seems to empty the washer faster. I also decided to replace the belt and bought a belt for under $10 on Amazon and it fit perfectly. Needless to say, I am very pleased with Amazon.
