Nominal value:
 
 
      Adjust opening pressure to 115 - 125 bar for new injector or injector to
      be newly adjusted, at least 110 bar for used injector. Depending on shim
      thickness the opening pressure is higher or lower. 0.02 mm produce a pressure
      differential of approximately 2 - 3 bar.
