Installing the high pressure lines
Special tools and workshop equipment required
t  Socket wrench insert -T40055-
t  Assembly sleeve -T10411-
t  Cleaning and degreasing agent, e.g. -D 009 401 04-
t  Protective goggles and gloves
  Note
t  Safety precautions when working on the fuel supply system → Chapter.
t  Observe rules for cleanliness → Chapter.
  Caution
t  For easier installation of the fuel high pressure pipe, release the tension of the fuel distributor. If necessary, slightly push the fuel distributor.
t  For easier installation of the injection pipes, release the tension of the fuel distributor as well as the clamping claws of the injection units. If necessary, slightly push the fuel distributor and slightly twist the relevant injection unit.
t  The pipes must on no account be bent or installed when under tension. The installation tension can lead to fracture of the fuel high pressure pipe.
  Note
t  It is not allowed to use tools for aligning the fuel distributor/the injection units.
t  Pay attention to the cylinder specific marking when re-using the high pressure lines.
t  The high pressure lines can be re-used if:
l  The sealing cone of the relevant high pressure line is not deformed or cracked.
l  The line boring is not deformed, constricted or damaged.
t  Corroded lines must no longer be installed.
–  Suction off dirt from the sealing cone at the fuel distributor.
  WARNING
Wear protective gloves and protective googles when working with grease remover!
–  Clean fuel line and line connection and blow-dry with compressed air.
–  Moisten threads of union nuts with fuel.
–  First position the injection lines from the fuel distributor to the injection unit by hand, only tighten the union nuts by hand.
–  Then install the high pressure line from the high pressure pump to the fuel distributor.
–  Only tighten the union nuts by hand.
Observe the following sequence:
   
–  Tighten the high pressure lines at the fuel distributor and at the injection units to 28 Nm using a socket wrench insert SW 17 -T40055-.
–  Tighten fuel distributor to 22 Nm.

–  For installing the high pressure line between the high pressure pump and the fuel distributor, slide the assembly sleeve -T10411- onto the fuel pressure sender -G247-.
  Note
  N23-10308
t  The bracket for the engine mounting must be movable in order to position the union nut on the high pressure pump, to do so slacken the screws -4-.
t  The assembly sleeve -T10411- ensures the correct distance between the fuel pressure sender -G247- and the high pressure line.
  N23-10286
–  First tighten the high pressure line -2- between the high pressure pump and the fuel distributor at the high pressure pump -4- and then at the fuel distributor -1-.
–  Screw on the screw -3- of the bracket for the fuel high pressure line.
–  Screw on bracket (for engine mounting).
l  Tightening torques → Chapter.
–  Check fuel system for tightness → Chapter.
