Camshaft Manufacturing

Chapter: C15

In Simple Terms

F1 camshafts must be made from iron-based alloy and carved from a single piece of material. Teams cannot weld different parts together to create the camshaft, ensuring all engines use consistently manufactured components.

  • Camshafts must be manufactured from iron-based alloy materials
  • Each camshaft must be machined from a single solid piece
  • Welding between front and rear bearing journals is strictly prohibited
  • This ensures fair competition and prevents teams from gaining unfair advantages through creative manufacturing
