This document is a technical engineering drawing for a U.S. Coast Guard (USCG) hub modification, specifically drawing number D050700. The detailed sectional assembly drawing depicts a precision mechanical component with specific dimensional specifications, including 12 holes, multiple hub sections, and a repositioned hub configuration. The drawing includes torsional data calculations, operating data (with RPM noted as 3500), and a comprehensive parts list detailing components like lock nuts, washers, and adapters. The drawing was created by Raymond Witt, dated 9-4-92, and appears to be a technical specification for a mechanical coupling or assembly used in Coast Guard maritime equipment.
