Leyparts Crankshaft

  • AL crnkshafts are nitrided for 42 hours, tested for endurance and dimensional accuracy in Precision Control Lab.
  • Hino crnkshafts are induction hardened under controlled conditions to achieve optimum hardness.
  • Made out of special grade material, drop forged Chrome molybdenum steel that is checked for perfect specific composition.
  • The micro structure,hardness and grain flow pattern are checked to withstand severe operational conditions to deliver to ultimate performance.
  • Crack detection is done through magnetized particles penetration process.
  • Hardness in EQUITIP electronic hardness testing equipment ensures wear resistance.


  • Nitrided (AL) and induction Hardened (Hino) to have hard surface.
  • Increased hardness and fatigue strength for longer life.
  • Uniform retention of oil on all journals for effective lubrication.
  • Free rotation and optimum power transmission
