K9K, and 750 or 752 or 760 or 762 or 766 or 768

Note: Vehicles equipped with the K9K*768 engine may or may not be equipped with an intercooler.

REMOVAL

I - REMOVAL PREPARATION OPERATION

• Remove the front engine cover.
• Disconnect the battery (see Battery: Removal - Refitting) (MR 392, 80A, Battery).

• Remove the inlet air duct (1).
• Disconnect the turbocharger pressure sensor connector (2).

K9K, and 750 or 760 or 762 or 766 or 768

• Loosen the clip of the air duct (3) between the intercooler and the inlet.
• Remove the air duct between the intercooler and the inlet.
• Remove the stainless steel pipe (4) between the turbocharger and the intercooler.

• Remove the dipstick bolts (5).
• Put the dipstick to one side.

• Remove the cover (6) from the injector rail protector.

• Disconnect the following connectors (7) :
  • the heater plugs,
  • the injectors.

• Disconnect:
  • the high pressure pump electrical connectors (8),
  • the diesel supply and return pipes (9),
  • the spherical injector rail pressure sensor (10).
• Fit the correct blanking plugs.
• Remove the bolts mounting the neck (11) onto the spherical injector rail.
• Move the electric wiring harness and neck to the side as shown by the arrow.
• Undo:
  • the high pressure pipe nut at the pump end using the (Mot. 1746),
  • the high pressure pipe nut at the injector rail end using the (Mot. 1746).
• Fit blanking plugs into the openings.

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove the accelerometer (12) using the (Emb.1596).

REFITTING

REFITTING OPERATION FOR PART CONCERNED

• Refit the accelerometer.
• Tighten to torque the accelerometer mountings (21 N.m) using the torque wrench.

WARNING

Before fitting a new high pressure pipe, lightly lubricate the nut threads with oil from the applicator provided with the new part.

Do not lubricate high pressure pipes supplied without an applicator, as these high pressure pipes are self-lubricating.

WARNING

Do not remove the blanking plugs from each component until the last moment.

• Remove the blanking plugs.
• Insert the high pressure pipe olive in the high pressure pump high pressure outlet taper.
• Fit, without tightening, the high pressure pipe nuts by hand, starting with the nut at the rail end.
• Slightly pretighten the high pressure pipe nuts.
• Torque tighten the high pressure pipe (24 N.m).
• Refit the neck on the injector rail.
• Tighten to torque the injector rail neck nuts (21 N.m)
• Connect:
  • the spherical injector rail pressure sensor,
  • the diesel return pipe connecting the injectors to the high pressure pump,
  • the diesel fuel supply and return pipes,
  • the high pressure pump electrical connectors.
• Connect the connectors of:
  • the injectors,
  • the heater plugs.
• Refit the injector rail protector cover.
• Insert the dipstick.
• Refit the dipstick bolts.
• Connect the inlet air pressure sensor.

K9K, and 750 or 760 or 762 or 766 or 768

• Refit the inlet duct and tighten its clip.
• Loosen the intercooler inlet air pipe nut on the alternator.
• Fit the air duct between the turbocharger and the intercooler air inlet pipe.
• Lock the air duct onto the turbocharger and the intercooler inlet air pipe.
• Tighten the bolt of the air duct on the rocker cover.
• Torque tighten the nut mounting the intercooler inlet air pipe on the alternator (8 N.m).

• Connect the battery (see Battery: Removal - Refitting).
• Prime the diesel circuit using the priming pump.

WARNING

Check that there are no diesel leaks:

• check the sealing after repair (see 13B, Diesel injection, High pressure pipe: Check, 13B-99),
• let the engine run at idle speed until the engine cooling fan starts to operate,
• accelerate several times at no load,
• carry out a road test,
• switch off the ignition,
• confirm that there is no diesel fuel leakage.

Note: When replacing the accelerometer, run command RZ004 using the Diagnostic tool in order to carry out the necessary programming.
