Information:
Exhaust Smoke Can Be Seen While Starting
Possible Causes/Corrections
Cold Outside Temperatures/It can be necessary to use starting aids, or to heat engine oil or coolant at temperatures below -12° C (10° F). Air in Fuel System/With air in the fuel system, the engine will normally be difficult to start, run rough and release a large amount of white smoke. If the engine will not start, loosen a fuel injection line nut and crank the engine until fuel comes out. Tighten the fuel line nut. Start the engine. If the engine still does not run smooth or releases a large amount of white smoke, loosen the fuel line nuts one at a time until the fuel that comes out is free of air. Tighten the fuel line nuts. If the air can not be removed in this way, put 35 kPa (5 psi) of air pressure to the fuel tank.
Do not use more than 55 kPa (8 psi) of air pressure in the fuel tank or damage to the tank may result.
Check for leakage at the connections between the fuel tank and the fuel transfer pump. If leaks are found, tighten the connections or replace the lines. If there are no visual leaks, remove the fuel supply line from the tank and connect it to an outside fuel supply. If this corrects the problem, the suction line (standpipe) inside the fuel tank has a leak. Low Quality Fuel/Remove a small amount of fuel from the tank and check for water in the fuel. If there is water in the fuel, remove fuel from the tank until it is free of water and fill with a good quality fuel. For more information see Special Instruction, Form No. SEHS7067, Fuel Recommendations For Caterpillar Diesel Engines.Change the fuel filter and "prime" (remove the air and/or low quality fuel from the fuel system) the fuel system with the fuel priming pump. If there is no water in the fuel, prime and start the engine by using an outside source of fuel. If engine starts correctly using different fuel, remove all fuel from the tank and fill with good quality fuel. Prime the fuel system if necessary. Low Fuel Pressure/Change the primary and secondary fuel filters and check to make sure the fuel lines are not plugged or damaged. If the filters or lines are not the cause, a repair or replacement of the fuel transfer pump is needed. Fuel Injection Timing Not Correct/Check and make necessary adjustments as in Testing and Adjusting section of this Service Manual. Valve Adjustment Not Correct/Check and make necessary adjustments as in Testing and Adjusting section of this Service Manual. Intake valve clearance is 0.38 mm (.015 in.) and exhaust valve clearance is 0.64 mm (.025 in.). Bad Fuel Nozzle(s)/Remove the fuel nozzles and test as in Testing and Adjusting section of this Service Manual. Low Compression/See Misfiring and Running Rough.Exhaust Smoke Can Not Be Seen While Starting
