Rework Procedure
Group Number 1
Injector Harness Inspection
-Raise the engine enclosure hood.
-Remove the air intake pipe connecting the air filter to the turbo inlet.
-Remove the valve covers.
-Inspect the injector harness wiring for contact between the harness and valve springs.
Image1.1.1
Repair
-If the harness is close to the valve spring, adjust the harness by disconnecting the injector connector rotating the connector 360 degrees and reconnecting it. This should slightly twist the wires and pull them away from the springs.
Image1.2.1
Injector Harness Replacement (If Necessary)
-If the injector harness has contacted the spring and cut the wire or exposed the wire, then replace the injector harness that is under the valve cover.
-When installing the new harness to the valve cover base make sure the tabs do not turn while torquing down the bolts(see the picture below). Keep the tabs straight, and this will help keep the wiring away from the valve springs.
Image1.3.1
Group Number 2
Injector Harness Inspection
-Remove the rear engine enclosure.
-Remove the clamp for flex boot on the air filter housing.
-Remove the rubber elbow on the inlet of the compressor side of the turbocharger.
-Remove the clamps called out in the photo for the turbocharger outlet pipe that connects to the aftercooler.
Image2.1.1
-Remove all three engine valve covers.
-Inspect the injector harness wiring for contact between the harness and valve springs.

Repair
-If the harness is close to the valve spring, adjust the harness by disconnecting the injector connector rotating the connector 360 degrees and reconnecting it. This should slightly twist the wires and pull them away from the springs.
Image2.3.1
Injector Harness Replacement (If Necessary)
-If the injector harness has contacted the spring and cut the wire or exposed the wire, then replace the injector harness that is under the valve cover.
-Remove the doors, hood, Clean Emissions Module (CEM) and mounting plate, and valve cover base.
-When installing the new harness to the valve cover base make sure the tabs do not turn while torquing down the bolts(see the picture below). Keep the tabs straight, and this will help keep the wiring away from the valve springs.
Image2.4.1
-Reinstall the previously removed hardware, and use the new 344-8311 exhaust clamp.
