Well I got the pump apart today and it was not too smooth. The most difficult part is the pulling the gear off the electrical motor. I destroyed the motor because of that small gear. That gear is pressed on and it is tight. You must pull it off to get the motor back together. The commutator has brushes riding on it and it is near impossible to get it together because the gear doesnt give you the room you need to get the brushes back in place. If you can get this gear off, a good cleaning and lubrication of the motor will probably do the trick to fix your problem. Since I ruined mine, I cut the mounting area off and epoxyed it to the new washer motor. I will mount it as the original was but position of the hose connections be different. Hope I helped a little bit.
