I recently purchased a used MP40 and it had a terrible shake upon installing it on the tank.
When de-coupled, the dry side is quiet so I put the wet side from my other MP40 on the new dry side, while on the tank, and the pump is quiet so I inspected the wet side to find that the magnet had high spots that were rubbing the wet frame cover.
I also noticed that when manually rotating the wet side magnet, it is out-of-round, causing a wobble from it being unbalanced.
Has anyone ever heard of the wet side magnet distorting this way?
