Help with Pump Problem

[hinejs]

No worth anyone's while to rebuild a motor nowadays. I recommend you pull the old motor off, remove the imellor, seal, and seal plate and replace with a new motor, shaft seal and seal plate gasket.

I agree.. If it's 11 years old, just replace it .

John,
The fact that it can run says there is nothing basically wrong. These are not brush type motors however there is a centrifugal starting switch that can get cruddy over time and all it takes is a small flat file or fine sandpaper and some time to clean the contacts. This switch is usually behind the back cover where the power line goes in so if you can remove that cover you will see it. From your description it sure sounds like the switch isn't closing when the motor is stopped and when power is applied you get a little vibration, humming, that causes it to close and start the motor.
Hope this helps and saves you $$$

Thanks everyone.

Poconos - thanks for the info. I'll check it out. There is a housing on the side of the motor where the wires go in to (looks like a solenoid on an automotive starter). This must be what you are talking about. I'll open it up and take a look and clean all the contacts and see if it does the trick.

Thanks again,
John

The thing that looks like a starter solenoid is probably the cover for the starting capacitor. On some motors these are external. Check this post

as it shows the back end of my Hayward. The black thing to the left is the starting cap and you can see the contacts I'm referring to. They are the inverted V things. When the motor comes up to speed a set of weights on the armature spring out and open the switch. Hope this claritifies things a little.

Thanks Poconos, that pic helps a lot. Now my only challenge will be getting access to the back end of the motor since it is only a couple inches from the wall (doh!). I'll figure out a way.

Thanks again fro your help.
