Technical Notes

The K03-1870EXA 4 82 turbocharger is a fixed-geometry unit, meaning it does not use variable turbine geometry or an actuator for vane control. The shaft nut secures the turbine shaft assembly, and correct installation torque is critical to prevent shaft play or bearing damage. Since no material grade or dimensional specs are provided in the input, verify the nut’s thread pitch and head size against your existing part or service manual. For PSA diesel applications (DW10ATED, DW12UTED), confirm the specific turbo variant, as K03 series parts can vary by engine displacement and power output. Always match the part number 5304-128-5003 to your turbo’s serial number or OEM reference before installation.
