Special Tool(s)

Removal
1. Remove the turbocharger pedestal.







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







3. Using the special tool, remove the IPR valve.







4. CAUTION: Use care when removing the pump cover. The 3 bolts remaining in the pump cover under the exhaust gas recirculation (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.







5. CAUTION: To prevent engine damage, do not pry off the high-pressure pump cover off 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.







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







7. Loosen the bolts on the high-pressure tube assembly.







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







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







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







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

Installation







1. CAUTION: To prevent engine damage, use only an approved pump cover seal. Substitution could 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 the 3 bolts.
- To install, tighten to 31 Nm (23 lb-ft).







5. Tighten the 2 high-pressure tube assembly bolts.
- To install, tighten to 11 Nm (8 lb-ft).







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 could fall out of the cover and fall down in 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: 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 the remaining bolts.
- To install, tighten to 11 Nm (8 lb-ft).







10. Using the special tool, install the IPR valve.
- To install, tighten to 50 Nm (37 lb-ft).







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