Special Tool(s)

Removal
1. Remove the turbocharger.
2. Remove the turbocharger inlet Y-pipe.







3. Remove the retaining nuts from the heat shield bracket.
- Position the ground wire aside.







4. Disconnect the wiring retainer from the back of the heat shield bracket.







5. Remove the bolts and heat shield.







6. Position back the heat insulating wrap and disconnect the fuel injection pressure regulator (IPR) valve electrical connector.







7. If equipped, unsnap and remove the heat insulating wrap.







8. Remove the IPR valve.







9. CAUTION: Use care when removing the pump cover. The 3 bolts remaining in the pump cover under the EGR cooler can fall out of the pump cover and into the engine under the high-pressure pump.

Remove or loosen the bolts as needed.







10. CAUTION: To prevent engine damage, do not pry the high-pressure pump cover from the pump or damage to the cover can occur.

Use a thin gasket scraper to separate the cover from the crankcase at the rear cover seam.







11. Position the special tool and check the oil pump drive gear backlash.







12. Remove the bolts on the high-pressure tube assembly.







13. Remove the bolts and the high-pressure oil pump.







14. Remove and discard the lower O-ring seals.







15. Using the special tool, disconnect and remove the high-pressure tube assembly.







16. Remove and discard the high-pressure oil pump O-ring seal.

Installation







1. CAUTION: To prevent engine damage, use only approved pump cover seal. Substitution can cause damage to the pump cover.

Install a new O-ring seal on the high-pressure oil pump.







2. Install the high-pressure tube assembly.







3. Install new lower O-ring seals.







4. Install the high-pressure pump and bolts.
- Tighten to 31 Nm (23 lb-ft).







5. Install the bolts for the high-pressure tube assembly.
- Tighten to 14 Nm (124 lb-in).







6. Position the special tool and check the oil pump drive gear backlash.







7. Install a new press-in-place gasket in the high-pressure pump cover.







8. Clean the cover mounting surface and apply sealer at the seams.







9. CAUTION:
- To prevent engine damage, use care when installing the high-pressure pump cover with fasteners. The 3 bolts in the cover can fall out of the cover and into the engine under the high-pressure pump.
- To prevent engine damage, the high-pressure oil pump cover must be firmly seated on the O-ring seal to prevent cracking the cover plate.

NOTE:
- Use a tool such as the Snap-on FRDH101 or GFRDH101 to aid in accessing the bolts under the exhaust gas recirculation (EGR) cooler.
- Apply clean engine oil to the high-pressure oil pump O-ring seal prior to installing the high-pressure pump cover.

Install the high-pressure oil pump cover and remaining bolts.
- Tighten to 11 Nm (8 lb-ft).







10. Install the IPR valve.
- Tighten to 50 Nm (37 lb-ft).







11. If equipped, install the heat insulating wrap and fasten the snap.







12. Connect the IPR valve electrical connector and position back the heat insulating wrap.







13. Install the heat shield and bolts.
- Tighten the large bolts to 49 Nm (36 lb-ft) and the small bolts to 11 Nm (8 lb-ft).







14. Connect the wiring retainer to the back of the heat shield bracket.







15. Position back the ground wire and install the retaining nuts.
16. Install the turbocharger inlet Y-pipe.
17. Install the turbocharger.
