I have a 1HP dynamo pool/spa pump that a friend gave me, when plugged
in it makes a humming sound but doesn't spin, I can't seem to get the
face off the main spinning rod
(as shown http://s87749883.onlinehome.us/pump.jpg
) Is there any trick
in doing so?
Are there any kind of bearings in the plastic face that could have
ceased? that could explain why it will not spin while the face is
attached with the 4 other long screws.
