Motor and impeller replacement

I need to replace my motor and impeller on a Hayword SP4010x15NS pump.  This model has been discontinued.  Two questions: should I just replace the entire pump or purchase parts to repair it.  If repairing it what are all the items that should be replaced?

Hello Daniel - If the pump body is in good shape, I would recommend replacing the impeller and motor. The motor is part number USN1152. The impeller kit is part number SPX4010CKIT. The impeller kit will include the shaft seal.
