For equivalent regional tools, refer to Special Tools .
- Use the EN-51092 alignment gauge (2) to ensure that the camshaft lobe is in the base circle position. At base circle position, the tool will be flush with the top surface of the Lifter Oil Manifold Assembly (1).
- Install a NEW high pressure fuel pump gasket (1).
- Install the high pressure fuel pump (2) and high pressure fuel pump cover (4).
- Start and hand-tighten the high pressure fuel pump bolts (5) evenly and tighten the high pressure fuel pump bolts to 25 N.m (18 lb ft).
NOTE:
The camshaft must be in the base circle position before the high pressure fuel pump is installed.
NOTE:
Ensure that the high pressure fuel pump roller lifter is oriented properly, the camshaft is at base circle and the number 1 piston is at top dead center (TDC) on the exhaust stroke.
NOTE:
Ensure the plastic bolt retainers (3) are installed in the high pressure fuel pump mounting holes before installing.
CAUTION:
Refer to Fastener Caution .
CAUTION:
Alternately hand-tighten the fuel pump bolts one turn at a time until the pump is fully seated. Trying to draw down the pump without even side-to-side tightening may result in pump plunger damage.
