These application paths serve as verification clues rather than confirmed fitment confirms. Buyers should cross-check part number 313590 against their specific turbo assembly and service documentation. Since no OEM reference numbers are provided in the source data, verify the part number, engine code, and production year before ordering. This approach helps ensure the correct replacement component is selected for your specific agricultural vehicle application.

Technical Notes

The S1B turbocharger series is a fixed-geometry unit commonly found in older agricultural and industrial diesel engines. This shaft nut secures the turbine shaft assembly, ensuring proper alignment and preventing axial movement during operation. Because no OEM reference numbers are supplied for this specific part, buyers should verify the part number 313590 against their existing turbo assembly or service manual. Confirm the specific S1B variant and mounting details on the Valtra Traktor BF75 or Valmet 320DS before ordering to ensure the correct replacement component is selected.
