Response to Hi I have a Northstar SP4020NS Serial #630A34 A. The pump motor is a two hp Century. I’m not sure of manufacturing year. The shaft seal that comes in the GO KIT66 has a larger inside diameter than the motor shaft so it doesn’t fit properly. Is this the wrong seal? What seal kit do I need?
