Troubleshooting Problems
Combustion Noise
Probable Cause
Poor Quality Or Water In The Fuel - Refer to Special Instruction, SEHS7067, "Fuel Recommendations For Caterpillar Diesel Engines". Also, Special Instruction, SEHS6947 has fuel correction factors and tables.The Wrong Timing Position Sensor Calibration - Refer to Electronic Troubleshooting for 3406E and 3456.Fuel Consumption Too High
Probable Cause
Poor Quality Or Water In The Fuel - Refer to Special Instructions, SEHS7067, "Fuel Recommendations For Caterpillar Diesel Engines". Also, Special Instruction, SEHS6947 has fuel correction factors and tables.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 Electronic Troubleshooting for 3406E and 3456.Wrong Timing Position Sensor Calibration - Refer to Electronic Troubleshooting for 3406E and 3456.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.Wrong Timing Position Sensor Calibration - Refer to Electronic Troubleshooting for 3406E and 3456.Too Much White Smoke
Probable Cause
Engine Misfire - Refer to Electronic Troubleshooting for 3406E and 3456.Wrong Timing Position Sensor Calibration - Refer to Electronic Troubleshooting for 3406E and 3456.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
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. Fuel can be eliminated from the crankcase by making repairs or replacements to the fuel injection lines and the nozzles.Failed Turbocharger Oil Seal - Check the inlet manifold and the aftercooler core for oil. The turbocharger should be repaired or replaced.Worn Valve Guides - See the Specifications module 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 the Specifications module for the specifications of the cylinder and the piston ring.Note: High wear at low hours is normally caused by dirt. This dirt comes into the engine with the inlet air.Low Oil Pressure
Probable Cause
Low Engine Oil Level - Check the engine oil level and fill to the proper level.Oil Leaks - Check for a loose oil filter or for loose oil supply lines. Check the crankshaft seals and the gaskets for the engine.Dirty Oil Filter Or Cooler Core - Check the operation of the bypass valve for the filter. As required, install new oil filter elements. Clean the oil cooler core or install a new oil cooler core. Remove the dirty oil and fill the engine with clean oil to the correct level.Diesel Fuel In Lubricating Oil - The reason may be an internal leak or worn piston rings. Make repairs, as needed. Remove any oil that contains diesel fuel. Install new oil filters and fill the engine with clean oil to the correct level.Too Much Clearance Between Rocker Arm Shaft And Rocker Arms - Check for the correct lubrication at the valve train. Install new parts, as needed.Oil Pump Suction Pipe Has A Defect - Replacement of the pipe is needed.Oil Pump Relief Valve - Clean the valve and the housing. Install new parts, as required.Faulty Oil Pump - Replace the oil pump.Too Much Clearance Between Camshaft And Camshaft Bearings - Inspect the bearings and the camshaft, replace as needed.Too Much Clearance Between Crankshaft And Crankshaft Bearings - Inspect the bearings and the crankshaft journals, replace as needed.Too Much Bearing Clearance For Idler Gear - Inspect the bearings and the idler gear, replace as needed.Piston Cooling Jets - Inspect the piston cooling jets, replace as is needed.Faulty Oil Pressure Gauge - Replace the oil pressure gauge.Engine Overheating
Probable Cause
Low Coolant Level - A sufficient amount of coolant will not go through the engine and the radiator if the coolant level is too low. This lack of coolant will not take enough heat from the engine. There will be insufficient radiator coolant flow. The heat will not be released into the cooling air. Low coolant level is caused by leaks or the wrong filling of the radiator. Make sure that the coolant can be seen at the low end of the filler neck on the
