About this file

Written by GovTribe AI ·

This document is a preliminary engineering technical drawing for an Air Intake Shield, specifically for a Cummins QSC8.3 Model, produced by the United States Coast Guard. The technical drawing provides detailed plan and side view schematics with precise dimensional measurements, including specifications for various components like shield housing, existing mounting clamps, and structural details. The drawing uses a 1/4"-1'-0" scale and includes a materials list, revision tracking, and weight control information. Key technical details include multiple plate references, shield attachments, and specific geometric positioning of components within the air intake shield assembly.
