Removal of the High Pressure Fuel Pump – Two-Filter System

Remove as follows:
1. Shut off the engine, apply the parking brake, chock the wheels, and perform any other applicable safety steps.
2. Disconnect the batteries. Refer to OEM procedures.
3. Open the hood.
4. If needed, remove the bumper. Refer to OEM procedures.
5. If needed, remove the splash shield. Refer to OEM procedures.
6. Remove the air filter housing. Refer to OEM procedure.
7. Remove the cold boost pipe. Refer to section "Removal of the Cold Boost Pipe (Charge Air Pipe)".
8. Remove the two bolts from the inspection cover on the bottom of the flywheel housing.
9. Install an engine barring tool (J-46392 or W904589046300 ) to the flywheel housing (1).

NOTE: When the flywheel dot is aligned with the edge of the pointer, the engine is at TDC.
10. Rotate the flywheel until the dot located on the inside tooth (2) of the flywheel is aligned with the edge of pointer (3).
11. Remove the Crankshaft Position (CKP) sensor.
NOTE: The crankshaft locking tool (W470589001500) MUST sit flush with the flywheel housing to be correctly
installed.
NOTE: If the crankshaft locking tool (W470589001500) does not sit flush with the flywheel housing, slowly rotate
engine using barring tool until the tool is flush with the flywheel housing.
12. Install the crankshaft locking tool (W470589001500) into the CKP hole.
13. Remove the fuel filter module. Refer to section "Removal of the Fuel Filter Module – Two-Filter System".
NOTICE: The high pressure fuel rail feed lines, vibration dampers, mounting bracket and hardware are one-timeuse components and MUST be replaced any time they are removed.
14. Remove the high pressure fuel rail feed lines from the high pressure pump to the fuel rail. Refer to section "Removal of
the High Pressure Fuel Rail Feed Lines - Two-Filter System".
15. Remove the high pressure fuel flange from the high pressure fuel pump. Refer to section "Removal of the High
Pressure Fuel Flange - Two-Filter System"
16. Disconnect the quantity control valve electrical harness connector.
17. Disconnect the plastic clip from the high pressure fuel pump mounting bracket.

Installation of the High Pressure Fuel Pump – Two Filter System

Install as follows:
NOTE: KM59 GEN1 high pressure fuel pump is equipped with a two-stage valve and a low pressure relief valve.
NOTE: KM63 GEN2 high pressure fuel pump is equipped with a two-stage valve.
1. Ensure flywheel is positioned at Top Dead Center (TDC) on cylinder number one.
2. If a new or remanufactured high pressure fuel pump is being installed, install the high pressure fuel pump drive gear on
to the high pressure fuel pump. Refer to section "Installation of the High Pressure Fuel Pump Drive Gear - Two-Filter
System".
3. If the high pressure fuel pump is being reused, clean mounting surface of high pressure fuel pump and O-ring groove.
4. If the high pressure fuel pump is being reused, install a new O-ring seal on to the high pressure fuel pump.
5. Lightly lubricate the high pressure fuel pump O-ring seal with clean engine oil.
6. Clean and inspect the flywheel housing bore for any burrs or other sharp edges; remove as necessary.
NOTE: The high pressure fuel pump should slide into the flywheel housing without binding. The mounting bolt
holes on the high pressure fuel pump housing should align closely with the mounting holes on the flywheel
housing.
NOTE: If high pressure fuel pump binds when being installed or if there is misalignment in the mounting bolt
holes, remove the high pressure fuel pump and verify the timing mark is at the 12 o'clock position and the engine
is at number one cylinder TDC.
7. Install the high pressure fuel pump to the cylinder block (KM59 GEN1 shown, KM63 GEN2 similar).

NOTICE: Ensure the correct bolt length is used when installing the high pressure pump. If an incorrect bolt length
(long) is used, the cup plugs installed in the cylinder block can be pushed out into the gear train causing severe
damage to the gear train. The correct bolt size is M10 X 35 mm (1.37 in.).
8. Install the four mounting bolts securing the high pressure pump to the cylinder block. Torque to 60 N·m (44 lb·ft).
9. Install the coolant line on to the cylinder block and air compressor.
10. Loosely install the high pressure pump bracket, and install the two nuts securing the high pressure fuel pump to the
bracket. Torque to 30 N·m (22 lb·ft).
