Hi, I was given the above motor which hadn't been run for years, and fortunately for me it ran first pop. I did notice that it was only intermitantly ejecting water so i changed the impeller (which looked ok anyway). I did however stuff up and did not check that the water pipe sat into the pump before assembly so I did the job again properly. Another problem i had was that when i removed the thermostat cover there was no thernostat. I cannot see this as being a major though, but i did find that the water was not circulating into the head. I forced water pressure in and this cleared any obstruction. Water poured into this cavity now ran down and out. However, now the pump seems to be functioning great except the motor gets very hot and the expelled water does too. So hot as i cannot put my hand in the expelled water. Is this normal? Or do I have a problem? I do not know the exact year as i have looked all over for a code and there doesn't seem to be one. I think it's about 1963.Thanks.
