Riello bearing lube?

What is the recommended lube for Riello motor bearings? I’ve got some off and on noise from my pump side bearing which I can see spin with the pump off when I turn the fan by hand.

I was thinking a spray that would creep in around the bearing so I don’t have to disassemble the motor to lube it but I don’t want the spray to clean any grease that might be there, definitely not WD-40! I want to try to quiet it down before swapping the motor. Thanks

    You can try anything light but they're permanently lubricated bearings in a nonservicable motor so when they get noisy it's time to replace the motor. Now you could attempt to disassemble the motor and find bearings for it but that might not work.

    Permanently lubricated motor. Don't touch.

    Ok thanks, I read somewhere else on the Internet that there were bearings you can replace in the Riello I wasn’t sure about mine
