  • Figure and Item Number.
  • Description (indicating subassemblies with asterisks).
  • DEC Part Number (including engineering drawing revision level).
  • ECO Cut-In (indicating top assembly drawing and revision at printing, plus additional revisions).
  • Used On Code (for product variations, or blank if universal).
  • Cross-references to other figures.
