Product review (5 stars): Perfect Part!
I ordered these parts for my Kenmore Model 665.16701890. One morning the dish washer did not wash the dishes but it could drain fine. After some research I learned that it could either be a clog or a broken impeller. In about 5 minutes into disassembly, I tried to remove the impeller. The impeller could spin independently of the motor, thus I could not remove it with basic screwdriver and wrench. The impeller was broken and needed to be replaced. The only way to remove the impeller was to cut it with a Dremel and wood chisel. After finally removing the top impeller, all the new parts fit perfectly. I recommend having a wet/dry vac on hand, there will be water, food, and garbage under the impeller and filter. Be sure not to suck up the little white balls. One rubber gasket in the kit was not needed for my dishwasher.

I have run the washer 7 times since replacing the parts, make sure to check for leaks.

You should be able to find installation videos on google by searching with the part number.
