Ecotech Marine MP40w ES operating noise

Personally mine are 10's... they have been checked(lined up... no spacers...) ... it is a hardware problem. The good one is very silent.

you're not using the spacer on the dry side? so your magnet is directly exposed to the glass?

The 10's don't have the pin style spacer, they just clamp on or if the glass is very thin below 3/16" i believe then there is a spacer to put in. The 40's have the pin spacer and the 60's have different spacer that slip on.

ohhh ok gotcha. well i found out why my mp40s were making noise. the pins on the spacers bent and were rubbing against the magnet. now they're perfectly silent

Are they quiet at 100% though? Mine are acceptable at lower power, but irritating at full.

They are aligned correctly, using the correct spacer setting, etc.

When you say your pins were bent, is this inside of the unit?

I've bought new bearings to try. I just need to get my hands on a bearing puller.

Yes mine are a 100% the pins are on the spacer on the dry side
