Agricultural machinery refurbishment

Produce component fabrication drawings based on supplied specifications for a harvester bearing block and pulley-and-bracket assembly.

AutoCAD · AS 1100 · Section views · Fits & tolerances

What I did

  • Prepared three component drawings and an assembly drawing for each assessment, using third-angle views, sections, dimensions and parts lists.
  • Documented materials, surface finishes and limits of fit so the component drawings could be read together as a complete assembly set.
