And just to be perfectly clear, the KM84 series caps are not usable with either the KM140 or the KM184 series.
I read a post on a pro audio board a couple of years ago from a guy who removed his KM184 capsule and then couldn't get it back together. I believe Neumann recommends NOT disassembling the cap and body. To do so undoubtedly would void any warranty you might have.
