GASKET 2941734 - Caterpillar

Introduction
The connection of battery cables to a battery and the disconnection of battery cables from a battery may cause an explosion which may result in injury or death. The connection and the disconnection of other electrical equipment may also cause an explosion which may result in injury or death. The procedures for the connection and the disconnection of battery cables and other electrical equipment should only be performed in a nonexplosive atmosphere.
Troubleshooting can be difficult. To repair the problem, refer to the possible causes and then refer to the corrective actions that are listed. Refer to your engine's Troubleshooting module 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 operates the engine. Knowing the details of the problem can save time. This will make the repair job faster and easier.Troubleshooting Problems
Combustion Noise
Probable Cause
Low Quality of Fuel or Water in the Fuel - Refer to Testing and Adjusting, "Fuel Quality - Test". Also, refer to Operation and Maintenance Manual, "Fuel Recommendations" for fuel specifications.Incorrect Timing Position Sensor Calibration - Refer to Troubleshooting for more information.Fuel Consumption Too High
Probable Cause
Low Quality of Fuel, or Water in the Fuel - Refer to Testing and Adjusting, "Fuel Quality - Test". Refer to Operation and Maintenance Manual, "Fuel Recommendations" for fuel specifications.Fuel System Leaks - Inspect the fuel system for leaks. As needed, make repairs or replacements.Excessive Idle Time - The engine should be shut off when the engine is not active.Fuel and Combustion Noise (knock) - Refer to your engine's Troubleshooting module for more information.Incorrect Timing Position Sensor Calibration - Refer to your engine's Troubleshooting module for more information.Excessive Black 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.Incorrect Timing Position Sensor Calibration - Refer to Electronic Troubleshooting for more information.Too Much White Smoke
Probable Cause
Engine Misfire - Refer to Electronic Troubleshooting for more information.Incorrect Timing Position Sensor Calibration - Refer to Electronic Troubleshooting 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 gasketToo Much Blue Smoke
Probable Cause
High Engine Oil Level - Do not put too much oil in the crankcase. If the oil level in the crankcase increases during engine operation, check for fuel dilution of the engine oil. If fuel dilution is detected, check for leaks in the injector sleeves. Also check fuel injectors that may be worn or damaged.Failed Turbocharger Oil Seal - Check the inlet manifold and the aftercooler core
