Tightening torques
flow actuator fixing screws 0.55 +/- 0.06 daN.m
IMPORTANT

Before any work on the injection system, use the diagnostic tool to check:

  • that the injection rail is no longer under pressure,
  • that the fuel temperature is not high.
  • Always observe the safety and cleanliness instructions given in this document during every operation.
  • Never loosen a high-pressure pipe connection while the engine is running.
WARNING
  • Use the special plug kit for the high-pressure injection circuit.
  • Always replace any high-pressure pipe and high-pressure pipe clips that have been removed.

REMOVAL

  • Remove the engine covers.
Actuateur de débit
  • Disconnect:
  • the battery,
  • the air intake duct (1).

  • Remove the high-pressure pipe (6) from injector No. 4 (see High-Pressure Pipes).
  • Fit plugs to the openings.
  • Loosen the two clamp screws (7).
  • Extract the flow actuator (proceed by hand in small successive turns).

CAUTION Do not use the electrical connector as a lever.

INSTALLATION

WARNING

Remove the protective plugs only at the last moment, for each component.

  • Unpack the new component just before fitting it.

CAUTION Do not damage the seal when refitting.

Note: Do not lubricate the seals with grease or used diesel. Use the sachet supplied in the new part kit.
  • Fit the actuator.
  • Start the two fixing screws by hand.
  • Tighten the two flow actuator fixing screws (0.55 +/- 0.06 daN.m) to torque using the "low torque" torque wrench tool.
  • Fit a new high-pressure pipe to injector No. 4 (see High-Pressure Pipes) and a new clip.
  • Reconnect:
  • the diesel return and supply pipes,
  • the electrical connectors.
  • Refit in the reverse order of removal.
WARNING

Connect the battery; carry out the necessary re-learns (see Electrical Equipment chapter).

WARNING

Check for diesel leaks:

  • Check for leaks after the repair (Diesel Injection chapter, High-Pressure Pipe: Leak Check, page 13B-48).
  • Run the engine at idle until the cooling fan starts.
  • Rev the engine several times without load.
  • Carry out a road test.
  • Switch off the ignition.
  • Check that there is no diesel leakage.
