08-20020_CAT966M BOOM TENSION ROD_package.pdf

This document is a technical drawing specification for components of the NASA Balloon Program, specifically detailing replacement parts for a boom tension rod assembly (NBOC MLV). The drawing provides detailed engineering specifications for multiple fastener and mechanical components including replacement tension rods, clevis tension rods, standard washers, hex nuts, smart bolts, and usable length pins with specific material requirements (AISI 1045 steel cold drawn, zinc plating, and graphite/aluminum anti-seize compound applications).

The document establishes detailed dimensional tolerances, surface finish requirements (microinches RMS unless noted), and fastener clearance specifications per ASME B18.2.8-1999 and ISO 273-1979 standards. Assembly instructions include torque specifications (85 foot-pounds), surface preparation procedures (deburring, rust/oil/grease removal, degreasing and drying prior to primer application), and multi-stage coating protocols using carboline carbozinc primer, carboacrylic midcoat, and topcoat per NASA-STD-5008. The parts list identifies seven key components sourced from suppliers including The Crosby Group, McMaster-Carr, and SmartBolt, with part numbers and specific quantities required. All dimensions are specified in inches unless otherwise noted, with design interpreted per ASME Y14.5-2009 standards. The drawing contains export control restrictions applicable to Cuba, Sudan, North Korea, Syria, Iran, and Ukraine, with violations subject to fines and imprisonment.
