High-Pressure Fuel Pump: Installation
- 1.NOTE: Only rotate the crankshaft Clockwise (CW) or damage to the engine may occur.NOTE: The cam lobe for the high-pressure fuel pump must be at BDC for the high-pressure fuel pump installation.
Rotate the camshaft as necessary until the cam lobe for the high-pressure fuel pump is at BDC.
- 2.
Lubricate the high-pressure fuel pump tappet and the high-pressure fuel pump drive unit bore with clean engine oil.
- 3.NOTE: Align the notch on the high-pressure fuel pump tappet and with the groove in the high-pressure fuel pump drive unit bore.
Install the high-pressure fuel pump drive tappet.
- 5.NOTE: Make sure that new high-pressure fuel pump bolts are installed.
Install the high-pressure fuel pump and loosely install the new high-pressure fuel pump bolts, alternately tighten each high-pressure fuel pump bolt one complete revolution until seated. Tighten the high-pressure fuel pump bolts in the following 2 stages.
Torque:
Stage 1: 44 lb.in (5 Nm)
Stage 2: 55 °
- 6.
Install the high-pressure fuel pump bracket, then install and tighten the high-pressure fuel pump bracket bolts.Torque: 150 lb.in (17 Nm)
- 7.
- 1.NOTE: Make sure that a new high-pressure fuel tube is installed.
Install the new high-pressure fuel tube, then install the high-pressure fuel tube flare nuts, the high-pressure fuel tube bracket bolt and the high-pressure fuel tube bracket nut finger tight at this stage.
- 2.NOTE: Calculate the correct torque wrench setting for the following torque using the Torque Wrench Adapter Formulas in the chart below.
Tighten the high-pressure fuel tube flare nuts in the following 3 stages.
Torque:
Stage 1: 62 lb.in (7 Nm)
Stage 2: 133 lb.in (15 Nm)
Stage 3: 30 °
- 3.
