Ok so i picked up a used MP40, brought it home , hooked it up and man was it loud. I tried every trick I knew of and decided it was the wet side, so I had a friend with a new wet side. Took it hope hooked it up and THE NOISE IS STILL THERE. Now here is a couple things I read about and tried
1. Replaced the wetside
2. Placed the dryside against the glass and turn it on , it was absolutely silent.
I dont get it. its like as soon as its engaged and or connected to the wet side the loud noise is back. I checked for spacing and everything i know of and the noise is there. If the bearings were bad wouldnt it make some type of noise when it was running without a wet side?
Please help I sold all my powerheads and Im at a loss for words.
