LINER-CYLINDER 7C5044 - Caterpillar

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 vehicle. 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
Note: Refer to the Truck Performance Diagnostic Guide, SEBD0808, "Truck Performance Complaints" for additional information. The Truck Performance Diagnostic Guide is also used for problems that are not engine related.Probable Cause
MPG Measurement Errors - Follow the vehicle high fuel consumption check list:
Correct measurement of the mileage
Correct measurement of the amount of fuel
Comparison to other trucks
Different truck or engine specifications
Different operating loads
Different operating modesPoor 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.Excess Road Speed Or Operation At High Engine Speeds - Reduce road speed and follow progressive shifting driving guidelines.Excess Wind Drag - Decrease the gap between the cab and the trailer. Add an air deflector.Brakes Dragging - Adjust or repair the brakes.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
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.Engine Misfires Or Runs Rough - Refer to the items that are listed in the "Problem 3: Too Much Black Or Gray Smoke" section. 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
