Not silent like my tunze, but much better. My wife said, that's supposed to be quiet? So I will continue to have my controller turn it off during dinner hours. But it is half the noise level as prior to bearing fix.

Interesting when I follow this my magnet rubs and the motor stalls. when I reverse it, it is about 50% more quite. But your washer/spring/washer order was what the problem was for me. The previous owner messed it up.

When I mount the motor assembly i the bell housing with a little caliper anti squeak silicone it is nice and quiet now. Previously it was noisy. BUT as soon as I screw on the magnet it is noisy as hell. My next step may be to balance the magnet.

When I mount the shaft assembly on the housing and give it a spin, then swap it and spin it again, I can hear and feel noise coming from the tank side (607) bearing.Or Did I confuse it already? Now I just need to find a more quiet tank side bearing.. While I have read that VBX and BOCA bearings had better results, there are those who had noise issues with them as well...So it may be constant trial and error till I get a good one.
