I replaced my 3/4 HP Polaris booster pump motor with a B625 A.O. Smith and ordered/used the Go-Kit 71V-9 for the seal and O-ring replacements. When I lined the pump back up, there was a large continuous leak from the seal area. Mind you, the booster pump was not even running. The leak was from the main pump pressure to the booster impeller/volute. I checked the seal installation and it seemed to be correct; however, the leak is large and the booster pump is not yet usable.
What did I do wrong? It's my 1st time to replace a motor/seals/O-rings; but I'm usually pretty good with repairs.
