REFITTING THE TURBOCHARGER OIL SUPPLY PIPE

REFITTING PREPARATION OPERATION

• parts always to be replaced: turbocharger oil supply pipe
• parts always to be replaced: Turbocharger oil supply pipe bolt

I - REFITTING OPERATION FOR PART CONCERNED

Note:

These two turbocharger oil supply pipes may be used on the same engine. The tightening torque of the end pieces (6) on the cylinder head is different, depending on the following:

• if the end piece is shouldered (5), in this case there will be no need to place the high-resistance bolt locking product on the end piece thread,
• if the end piece is not shouldered (4 ), it is essential to apply high-strength threadlock to the end piece threading.

• Refit a new turbocharger oil supply pipe.
• Fit without tightening:
  • the turbocharger oil supply pipe nut on the cylinder head,
  • the turbocharger oil supply pipe hollow bolt.
• Torque tighten:
  • the turbocharger oil supply pipe hollow bolt (turbocharger end) (torx head bolt 18 N.m or bolt with head type H 14 N.m),
  • the turbocharger oil supply pipe nut (cylinder head side) collar nut 35 N.m or non-collar nut (23 N.m) using tool (Mot. 1746).
• Clip the cooling hoses onto the cylinder head water chamber.

II - FINAL OPERATION

• Fit:
  • the turbocharger air outlet pipe,
