This copper shaft serves as a critical component in the valve train, responsible for transmitting motion from the rocker arm to the valve. Its precise dimensions—31.60 mm in length and inner and outer diameters—are tailored to fit within the assembly, ensuring smooth, unhindered movement. Copper’s excellent thermal conductivity allows for efficient heat dissipation, which helps prevent overheating during heavy-duty operation. Its durability and resistance to wear make it an essential part for maintaining consistent valve timing and operation. Properly functioning shafts like this reduce mechanical stress and noise, ultimately contributing to engine longevity and performance. The copper material’s resilience against corrosion and high temperatures ensures reliable operation over the engine’s service life.
