Introduction
Troubleshooting can be difficult. To make a repair to a problem, refer to the possible cause and the corrective action. Also, refer to the Troubleshooting manual for more information.This list of problems, causes and corrections will only give an indication of the location of a possible problem. This will also list the type of repairs that are needed.Service personnel may remember similar complaints which were corrected by a previous method of troubleshooting. A similar complaint can have a different cause.Get a good description of the problem from the operator and/or the person that owns the equipment. Knowing the details of the problem can save time. This will make the repair job faster and easier.Troubleshooting Problems
Problem 1: Loud Combustion Noise
Probable Cause
Poor Quality Or Water In The Fuel - Find the source of contamination. Remedy the suspect source.The Wrong Timing Position Sensor Calibration - Refer to Troubleshooting, "Timing Calibration".Problem 2: Fuel Consumption Too High
Probable Cause
Poor Quality Or Water In The Fuel - Find the source of contamination. Remedy the suspect source.Fuel System Leaks - Inspect the fuel system for leaks. As needed, make repairs or replacements.Excess Idle Time - The engine should be shut off when the engine is not active.Fuel And Combustion Noise (knock) - Refer to Troubleshooting, "Engine Misfires, Runs Rough, or Is Unstable" for more information.Wrong Timing Position Sensor Calibration - Refer to Troubleshooting, "Timing Calibration" for more information.Problem 3: Too Much Black Or Gray Smoke
Probable Cause
Not Enough Air For Combustion - Check for a plugged air cleaner element or for blockage in the air lines. Refer to Testing And Adjusting for the procedures to check inlet manifold pressure and aftercooler core leakage.Wrong Timing Position Sensor Calibration - Refer to Troubleshooting, "Timing Calibration".Problem 4: Too Much White Smoke
Probable Cause
Engine Misfires Or Runs Rough - Refer to "Too Much Black or Gray Smoke". Refer to Troubleshooting, "Engine Misfires, Runs Rough, or is Unstable" for more information.Wrong Timing Position Sensor Calibration - Refer to Electronic Troubleshooting, "Timing Calibration" for more information.Coolant In The Combustion System - White smoke can also be caused from the following problems.
Coolant in the combustion chamber
A cracked cylinder head
A cracked cylinder liner
A faulty cylinder head gasketProblem 5: Too Much Blue Smoke
Probable Cause
Too Much Oil In The Engine - Do not put too much oil in the crankcase. If the oil level in the crankcase increases during engine operation, check for fuel in the crankcase.Failed Turbocharger Oil Seal - Check the inlet manifold and the aftercooler core for oil. The turbocharger should be repaired or replaced.Worn Valve Guides - Refer to Specifications, "Cylinder Head Valves" for the maximum permissible wear of the valve guides.Worn Piston Rings - Worn piston rings and/or cylinder walls can be the cause of blue smoke and a loss of compression. Make a visual inspection of the cylinder walls and the piston rings. If necessary, measure the cylinder walls and the piston rings. Refer to Specifications, "Piston and Rings" for
