Incorrect oil
•
Contaminated oil
•
Leaks in air intake system
•
Dirt in fuel

Recommended Actions
Multiple Starts or Cold Operation
Frequent starting and stopping of the engine can
cause early wear. Also, operation of the engine for
short periods of time in cold conditions can cause
early wear.
Incorrect Maintenance Intervals
If the engine is not correctly maintained, early wear
will occur.
Make sure that the engine is maintained at the
correct maintenance intervals. Refer to the Operation
and Maintenance Manual, “Maintenance Interval
Schedule”.
Dirt in Engine Oil
1.
Drain the oil from the crankcase and re
fi
ll the
crankcase with clean engine oil. Install new engine
oil
fi
lters. Refer to the Operation and Maintenance
Manual for more information.
Incorrect Oil
1.
Check that the engine is
fi
lled with oil of the
correct speci
fi
cation. Refer to the Operation and
Maintenance Manual, “Re
fi
ll Capacities and
Recommendations”.
2.
If necessary, drain the engine oil system and
re
fi
ll the engine oil system. Refer to Operation
and Maintenance Manual, “Engine Oil and Filter
- Change”.
Contaminated Oil
Check an oil sample for contamination with fuel. If
contamination is found, investigate the cause.
Leaks in Air Intake System
A leak in the air intake system may allow un
fi
ltered
air into the engine. Inspect the air intake system for
streaks which may indicate a leakage of un
fi
ltered
air. Inspect all of the gaskets and the connections.
Repair any leaks. Refer to Testing and Adjusting, “Air
Intake System” for more information.
Dirt in Fuel
1.
Remove the fuel
fi
lters. Inspect the fuel
fi
lters for
contamination. Install new fuel
fi
lters. Refer to
the Operation and Maintenance Manual, “Fuel
System Filter- Replace” and Operation and
Maintenance Manual, “Fuel System Primary Filter
(Water Separator) Element - Replace”. Determine
the cause of the contamination.
2.
Check the diesel fuel for contamination. Refer to
Testing and Adjusting, “Fuel Quality - Test”.
Low Oil Pressure
Refer to Troubleshooting, “Low Engine Oil Pressure”
for the testing procedure. Repair any identi
fi
ed faults.

Engine Mis
fi
res, Runs Rough
or Is Unstable
The probable root causes are listed in order below:
Note:
If the fault is intermittent and the problem
cannot be duplicated, refer to Troubleshooting,
“Intermittent Low Power or Power Cutout”.
Note:
If the fault only occurs under certain conditions,
test the engine under those conditions. Examples
of certain conditions are high rpm, full load and
engine operating temperature. Troubleshooting
the symptoms under other conditions can give
misleading results.
Probable Causes
•
Diagnostic codes
•
Speed demand input
•
Air intake and exhaust system
•
Glow plugs
•
Valve lash
•
Fuel supply
