Response to Hi Peter, The motor on this page is the correct replacement for your 177450 motor. We would suggest a Tune Up Kit when replacing your motor but we would need to know the make and model of your pump. Common pump models are the Pentair Whisperflo, Pentair Challenger, Jandy Stealth, etc.. Could you give us the model information for your pump, simply click the reply link below to do so.
