Technical Notes

The S500 turbocharger is a large-displacement unit typically found in heavy-duty marine and industrial applications. This shaft nut secures the turbine shaft assembly, and its integrity is critical for maintaining proper bearing alignment and preventing shaft play. The visible hexagonal profile and internal threads allow for standard torque application during reassembly. Since no specific material grade or thread pitch is confirmed in the supplied data, buyers should verify the exact thread specification against their existing hardware or engine service manual. Technical fitment support is available to assist with reference checking this part against specific S500 configurations.
