NIKON - Nikon AFS DX Nikkor 18 135mm f35 56G ED Service

Official service manual for the Nikon AF-S DX Zoom Nikkor 18-135mm f/3.5-5.6G ED lens (model JAA79651). This detailed workshop manual provides service technicians with comprehensive specifications and step-by-step disassembly and reassembly procedures. The optical design features a 15-element, 13-group construction including one ED (extra-low dispersion) element and two aspherical lens elements, covering the 18-135mm focal length range with maximum apertures of f/3.5 at wide angle and f/5.6 at telephoto. Internal focusing is driven by a Silent Wave Motor for fast, silent autofocus operation. Disassembly procedures systematically guide technicians through removal of major lens groups, including the 1st and 2nd lens group units, with precise identification of the specialized service tools required at each step. Critical safety instructions cover mandatory optical alignment procedures that must be performed at properly equipped service facilities following removal of the 5th lens group housing. The manual specifies proper handling and application techniques for lead-free solder materials throughout the lens, including soldering iron temperature and material composition requirements. Technical illustrations clearly document external components such as the zoom rubber ring, protective tape applications, and rear cover ring assemblies to ensure correct reassembly.
