LUV951, a friend of mine has a new MP10W (non ES) and it does make some noise. after a few weeks, it has quieted down.
Vortech pumps will never be DEAD silent like a full internal pump. this is because there is no water to hide or muffle the sounds of the pumps.

really!! thats very interesting to know.
do you think they were just cheap ceramic bearings, or needed to break in, or do you not know? (very curious)
also, do you think it could be from installing them? maybe ceramic bearings are too delicate to be pressed on?

Any updates from anyone who's replaced their bearings? I picked up a used MP40 and it's noisy enough to hear from 20ft away (whirring sound, more evident during when rpms ramp up). I plan on replacing the bearings and will see what's available locally at the RC shops; otherwise, bocabearings.com has alot of options.

Thanks,
Glenn

Can anyone tell me what the correct order of the washers is? I pulled mine apart ages ago and forgot the order of the washers that sit between the bearings and the motor casing.

i think mine just had a spring washer and a flat washer. in page 1, you can see the spring washer toward the bearing/mag. so i would say put it there, and the flat washers if any between the spring washer and case.

the washers go on the back side of the Dry side. that way they push toward the glass and arnt fighting the magnets pulling on each other.

this is a fantastic thread. I have been shopping for a bargain MP40, but was afraid to get a worn one. Nice to know you can upgrade some major problems easily even for an old one.

I also heard that you can do a firmware upgrade of a GEN1 to a GEN2, but until I get my hands on one I can't verify it.

That makes sense. I'm at work now so it will have to wait until this evening.
Thanks.

dont know i did wait for week or so to see if the sound would get better, but it did't change , now that i think about that they may be, about installing them i was carefull too, i dont think that was a reason.
