Technical Notes

The S400 turbocharger is a fixed-geometry unit commonly found in heavy-duty diesel engines. As a piston ring, this part does not involve variable-geometry vanes or actuator systems. The visible C-ring profile with a single gap is standard for sealing the piston bore. No specific material grade or dimensional data is provided in the input, so buyers must verify internal dimensions against their existing S400 unit. For rebuild jobs, inspect the piston bore and ring groove for wear before installation to ensure stable operation. Technical fitment support is available to confirm that part number 315536 matches your specific turbocharger configuration.
