Information:

Use the following tests for troubleshooting and repair steps. Use the ""Test for Cylinder Cutout"" in order to determine if the replacement of individual injectors is needed. Replace suspect injectors with the part number of the original injector. Use the ""Test for Leakage from Poppet Valve"" in order to determine if the full set of injectors need to be replaced. For replacement of the full set of injectors, use the current injectors and new software that is listed in Table 2.Test for Cylinder Cutout
The cylinder cutout test should be used in order to determine if an individual injector may have caused the failure.
Warm the engine out of cold mode.
Connect Cat ET to the engine while the engine is running.
Ensure that the engine speed is 1200 rpm 125 rpm. An extremely rough running engine will need to be diagnosed by other methods.
Cut out one bank of cylinders. Note engine rpm and the fuel position on the Cat ET screen at that time.
Cut out one of the remaining cylinders from the cylinder bank that is running. Allow the engine to stabilize, and note the fuel position.
Give power back to that cylinder. Allow the engine to stabilize. Note the fuel position.
Repeat steps 5 through 6 until the cylinder bank has been completely checked.
Power all cylinders. Allow the engine to stabilize.
Cut out the other cylinder bank and repeat steps 5 through 8.
Repeat steps 4 through 9 with the engine at 2000 rpm.
Compare the results from the fuel position from each cylinder.
If the cylinder was cut out and the fuel position did not change the cylinder may not have been producing power. This cylinder would be suspect.
When you are finished with the test, reduce engine RPM to low idle. Shut off the engine.
Replace any suspect injector with a similar original injector. Install new seals for the injector and the jumper tube during this repair. The repair procedure for the injector is found in Special Instruction, REHS0116.It is possible that multiple injectors are functioning improperly. Complete ""Test for Leakage from Poppet Valve"" in order to evaluate possible excessive leakage from the injectors.Test for Leakage from Poppet Valve
Warm the engine out of Cold Mode to normal operating temperature.
Turn off the engine.
Remove the valve cover bolts in preparation in order to observe the injectors. Leave the covers in place.
Hot oil and components can cause personal injury.Do not allow hot oil or components to contact skin.
Restart the engine and run at low idle with no load.
Use Cat ET in order to perform the test that overrides the injection actuation system. Increase injection actuation pressure to the maximum value.
Observe all of the injectors under each valve cover for leakage at the spill port. A small amount of dripping is acceptable. However, a continuous stream of oil is an indication of excessive leakage of the poppet valve. Only leaks at the spill port are an indication of excessive leakage from the poppet valve.
If multiple injectors display excessive leakage from the poppet valves, update the set of injectors with
