Verify production year and any mid-production updates to avoid fitment issues.

Technical Notes

The S1B turbocharger is a fixed-geometry unit, meaning it does not use variable turbine vanes. This piston ring functions as a sealing component within the assembly, helping maintain oil control and compression integrity. Since no specific material grade or dimensional data is provided, buyers should verify the ring's physical dimensions against their existing turbocharger configuration. For Deutz BF4M2012C or Valtra Traktor BF75 applications, confirm the engine code and production year to ensure the 311857 part number matches the specific turbo variant installed. Technical fitment support is available to assist with reference checking if OEM reference numbers are not immediately available.
