Mp40 brand new HELP

cactusreef · 2026-09-12T19:46:41-0400

I just got two mp40s. One is fine and working well. One has the wet side start vibrating and moving around and falling off and making noise. What can I do here? I took it apart and didn’t notice anything. My glass thickness is at the higher end of the spacer. Can I use the smaller one? I’m pretty annoyed considering how much I spent on these.

I put the smaller size spacer on and I think it’s working…for now….

Also it’s pretty hot. Does the dry side get pretty hot?

Mine would get pretty warm depending on the mode and speed.

remove the spacer and just use the rubber sticker.

Yeah I guess this is the move. Thanks!
