    I have just replaced a Grundfos MQ 3-35 due to being very noisy.
    I have followed the service guide to disassemble the unit and have removed the pump...which looks good externally, but not turning smoothly.
    Is it possible to open the motor and replace bearings, or is it a case of replacing with a new pump?
    Thank you.
