NIKON - Nikon Bulletin FM2N Shutter
by NIKONTechnical bulletin from Nikon dated January 1985 addressed to authorized service centers. This bulletin announces the availability of shutter curtain blade replacement for FM2, FE2, and FA cameras, in accordance with technical information FM2-840024. The document details five major improvements made to the shutter system starting from 1982-1983, addressing issues related to the 0.02mm thick shutter curtains experiencing warping during travel across the aperture. Improvements include inner aperture frame re-contouring to prevent interference, honeycomb structure reinforcement for the closing curtain, closing curtain arm material change from titanium to carbon steel for added strength, closing curtain brake enhancement with spring addition, and rivet modification to prevent blade dislocation. The bulletin provides detailed illustrations of each modification, comprehensive replacement procedures, installation instructions, and performance verification guidelines. A parts reference table lists specific part numbers and FOB pricing for all camera models, emphasizing the importance of careful handling of these thin shutter curtains and customer education regarding proper maintenance.
