Product review (5 stars): Fairly easy repair, took about an hour
Fairly easy repair, took about an hour.  Google for a repair video, without it you would never figure it out.  One thing. depending on the model, the pump might be buried where you can't get to it.  I took the short hose off the bottom of the tub, which allowed me to rotate the motor.  What you don't see on the videos, is that it is really greasy and oily.  Have a couple of old towels, to protect the floor and sop up any water that comes out, if you have to disconnect the pump hose.  Any grease that ends up on the floor can be removed with rubbing alcohol. The hardest part is putting the @#^$ clip on the clutch.

Other than a shaft extension for your ratchet wrench, no special tools are required.  You should replace the hoses when you do this, No-one ever does, including me, until they burst.
