FAQ

What work fits NAICS 336310?
  • Production of complete gasoline engine assemblies built to OEM drawings and delivered with dynamometer performance test certificates and serial-numbered documentation.
  • Manufacture of machined engine blocks and cylinder heads with specified heat-treatment processes, dimensional inspection reports, and material certification.
  • Fabrication of rotating components such as crankshafts, camshafts, and connecting rods supplied with balancing reports and metallurgical traceability.
  • Supply of peripheral engine subassemblies including intake manifolds, timing covers, and valve-train assemblies manufactured to fit designated engine families.
When is NAICS 336310 a weak fit?
  • Diesel engine manufacturing where the missing element is diesel fuel system design and combustion characteristics specific to diesel engines and a different industry classification.
  • Motor vehicle assembly plants where the missing element is final vehicle assembly and integration as opposed to engine and component manufacturing.
  • Automotive parts wholesale or distribution activities where the missing element is in-house manufacturing and fabrication of engine parts rather than resale and inventory management.
What solicitation language points to NAICS 336310?
  • Specifications call for engine-family dynamometer test reports, torque and power curves, and acceptance criteria at specified operating points.
  • CLINs list machined engine castings and components requiring heat-treatment records, dimensional inspection reports, and material traceability documentation.
  • Contract language requires production to match OEM engineering drawings, specified assembly torque values, and delivery of serial-numbered engine units with performance test certificates.
