Follow along for a hands-on demonstration that highlights performance points. In this video, we'll show you how the 6261-41-4900 EGR Valve Assembly functions in Komatsu PC400-7, PC450-7, and other compatible excavator models. Watch as we explain the EGR system's role in reducing NOx emissions, identify common failure symptoms like rough idle and power loss, and demonstrate proper installation techniques for optimal performance and emissions compliance.
