This is a technical engineering drawing for a D-2311 Main Shaft component, featuring detailed specifications for a gear shaft assembly. The drawing includes comprehensive specifications for a 20-tooth gear with 11 diametral pitch, 20-degree pressure angle, and various critical dimensions including pitch circle diameter, addendum, and root measurements. The shaft requires specific material (AISI 9310 AMS 6260) and processing steps including turning, annealing, copper plating, heat treating, and grinding.

Key manufacturing requirements include hardness specifications (Rockwell "A" 81-85 for case, Rockwell "C" 30-40 for core), copper plating thickness of .002 minimum, tin flash coating of .0006-.0008 thickness per AMS 2408, and precise concentricity requirements of .004 F.I.R for outside diameters. The drawing includes multiple detailed views and sections showing critical features, thread specifications, and dimensional tolerances. This technical data is restricted to U.S. citizens or permanent legal residents per DOD Directive 5230.25 and is associated with NAWC contract N00421-18-P-0734.
