Technical Notes

The S400 turbocharger is a fixed-geometry unit commonly found in heavy-duty diesel applications. As a shaft nut, this fastener secures the turbine shaft assembly; correct torque and thread engagement are critical for maintaining shaft alignment and preventing vibration during operation. Buyers should verify the thread specification and head style against their existing component. For KOMATSU PC400-7 or Mercedes-Benz OM501LA units, confirm the specific turbo serial number to ensure the 167799 part matches the required configuration. Technical fitment support is available to assist with these verification steps.
