[SIZE=4]Just yesterday I successfully completed the job of replacing the motor coupling and isolator on the washer. Following the step-by-step instructions I found online, after removing the cabinet I began the procedure to remove the pump. I discovered that the pump bearing was frozen on the motor shaft. No matter how much I wiggled, pulled, pryed, and prodded, it would not break loose from the shaft. I even worked some penetrating lube into it and let it "soak" for an hour. It still would not budge even a fraction. After some further study I finally recognized that the pump really didn’t have to be removed, that the motor and pump would come off as one unit. I proceeded with the job on that basis and all went well. Now the washer is working fine again except that the pump has begun to leak substantially…exactly what I feared would happen after struggling with it for so long! Obviously, the pump must now be replaced, but how do I break it loose from the motor shaft?! What method would you recommend? I considered the possibility of hacking the plastic-bodied pump apart to gain more direct access to the bearing and shaft, but is that a reasonable thing to do? PLEASE HELP!!![/SIZE]
I have fixed this problem many times. Hold the pump in one hand, and pound on the pump housing with a hammer, being carefull not to hit the motor. Just pound on the pump to drive it off the motor shaft, works every time.
If you have a large vise, you can clamp the motor in it and do the same pouding.
