Mp40qd Sounds like a jet engine

[McFish]

Bought a used mp40qd on eBay that isn’t quiet - i guess it needs new bearings?

Anyone know how to fix this issue?

There is a reef central thread that tells you where to order the parts from and everything. It has photos of how to do it step by step.

Are you running it 100%? They tend to be pretty noisy and run hot at 100% but usually fine if lower then that. You can also pull the wet side apart and make sure there isn’t any junk in and around the magnet
