Description

 

The crankshaft for CAT 3406 engine is a core load-bearing component exclusively designed for heavy-duty excavators equipped with CAT 3406 diesel engines. As the "power transmission core" of the engine, it converts the reciprocating motion of pistons into rotational mechanical energy, directly driving the excavator’s working devices (such as bucket and arm) and traveling system to realize digging, lifting and other operations.
Crafted in strict compliance with CAT’s OE manufacturing standards, this crankshaft is made of high-strength forged alloy steel through precision forging and multi-stage heat treatment processes. Its structure includes main journals, connecting rod journals, crank arms and balance weights, all of which are tailored to the 3406 engine’s cylinder layout and power parameters. Each crankshaft undergoes rigorous dimensional accuracy detection (with journal roundness error ≤0.005mm), dynamic balance testing and fatigue strength verification to ensure seamless matching with the engine’s cylinder block, connecting rods and other components. It is widely applicable to large excavators in construction, mining and infrastructure projects, adapting to the high-load, frequent impact working conditions of excavators.

 


Advantage

  • OE-Grade Matching & Installation Convenience: 100% compatible with CAT 3406 engine assemblies, with consistent main journal diameter, connecting rod journal spacing and mounting positioning. It can be directly assembled without modifying the engine block or related components, greatly reducing the difficulty and time of maintenance replacement.
  • Super High Structural Strength: Adopts integral forging process and quenching-tempering heat treatment, the tensile strength reaches 1200MPa, and the fatigue life is more than 3 times that of cast crankshafts. It can withstand the maximum instantaneous impact load of 800kN during excavator operation without deformation or fracture.
  • Precision Balance & Vibration Reduction: Through high-precision dynamic balance correction (unbalance amount ≤5g·cm), the vibration amplitude of the engine during operation is reduced by 40%. This not only reduces the wear of the engine’s bearing bush and cylinder liner, but also improves the comfort of the excavator operator.
  • Wear Resistance & Corrosion Protection: The journal surface is treated with nitriding and polishing, with a hardness of HV600-700 and a roughness of Ra0.2. It has excellent wear resistance and can maintain good fit with the bearing bush after 15,000 hours of operation; the surface anti-rust coating effectively resists corrosion from engine oil and coolant.
