  1. Cam Follower Replace if damaged.
  2. O-ring Always replace Before installing, lubricate with clean engine oil.
  3. High Pressure Pump with Fuel Pressure Regulator Valve -N276- Removing and installing, refer to «HIGH PRESSURE PUMP»(ref-475526-S04018469522012052300000) .
  4. Bolt 10 Nm
  5. Union Nut 27 Nm Counter hold the threaded connection when loosening. Check the tightening specification for the threaded connection to the high pressure pump before installing. Install the high pressure pipe free of stress.
  6. High Pressure Pipe Follow the safety measures for releasing the high side fuel pressure. Refer to «HIGH SIDE FUEL PRESSURE, RELEASING»(ref-475570-S34811348802012052300000) .
  7. Threaded Connection 30 Nm On vehicles from 06.06. Replace only after it has been loosened.
