About this file
This is an engineering drawing package showing detailed specifications for replacement wheel designs for the B. Everett Jordan Dam service gate in Moncure, NC. The drawings include section and elevation views of wheel assemblies with precise dimensional requirements and tolerances.
The wheels are to be manufactured from ASTM A564 Type 630 Class H1150 material with a minimum yield strength of 105 KSI. Key specifications include a rim minimum hardness of BHN 321 x 1/2 deep requiring heat treatment, and a minimum surface finish of 500 μin. The main wheel diameter is 18.000" (+0.005"/-0.000") with various smaller feature dimensions and bolt patterns detailed in both section and elevation views. The drawings are marked as preliminary for review and include standard engineering tolerances and interpretation notes per ASME Y14 standards. The package consists of two drawing sheets (BD-01 and BD-02) showing different views and details of the wheel assembly.
