    الشرح باللغة الانجليزية نقلا عن منتداي اردت ان اضيفه داخل منتدي المهندسين العرب للافادة

    Troubleshooting
    Troubleshooting can be difficult. The Troubleshooting Problem List gives a list of possible problems. To make a repair to a problem, make reference to
    the cause and correction on the pages that follow.
    This list of problems, causes, and corrections will only give an indication of where a possible problem can be, and what repairs are needed. Normally,
    more or other repair work is needed beyond the recommendations in the list.
    Remember that a problem is not normally caused only by one part, but by the relation of one part with other parts. This list is only a guide and cannot
    give all possible problems and corrections. The service personnel must find the problem and its source, then make the necessary repairs.

    Problem 1: Engine Crankshaft Will Not Turn When Start Switch Is On

    Problem 1: Engine Crankshaft Will Not Turn When Start Switch Is On

    Probable Cause:

    1. Battery Has Low Output
    Make Reference to Problem 26.

    2. Wires Or Switches Have Defect
    Make Reference to Problem 26.

    3. Starting Motor Solenoid Has A Defect
    Make Reference to Problem 26.

    4. Starting Motor Has A Defect
    Make Reference to Problem 26.

    5. Inside Problem Prevents Engine Crankshaft From Turning
    If the crankshaft can not be turned after the driven equipment is disconnected, remove the fuel injection nozzles and check for fluid in the cylinders when the crankshaft is turned. If fluid in the cylinders is not the problem, the engine must be disassembled to check for other inside problems. Some of these inside problems are bearing seizure, piston seizure, or wrong pistons installed in the engine.

    Problem 2: Engine Will Not Start

    Probable Cause:

    1. Starting Motor Turns Too Slow
    Make reference to Problem 27.

    2. Dirty Fuel Filter
    Install new fuel filter.

    3. Dirty Or Broken Fuel Lines
    Clean or install new fuel lines as necessary.

    4. Fuel Transfer Pump
    At starting rpm, the minimum fuel pressure for fuel transfer pump must be 20 kPa (3 psi). If fuel pressure is less than 20 kPa (3 psi), change the fuel filter element. Look for air in the fuel system. If fuel pressure is still low, install a new fuel transfer pump.

    5. No Fuel To Cylinders
    Put fuel in fuel tank. "Prime" (remove the air and/or poor quality fuel) the fuel system.

    6. Poor Quality Fuel
    Remove the fuel from the fuel tank. Install a new fuel filter element. Put a good grade of clean fuel in the fuel tank. See Diesel Fuels and Your Engine, SEBD0717.

    7. Wrong Fuel Injection Timing
    Make adjustment to timing.

    8. Shutoff Solenoid Will Not Move To Extended Position
    The solenoid must get electricity to stop the engine. Operate the control for the shutoff solenoid and see if the solenoid makes a noise (clicking sound). If this sound can be heard and the engine will not start, remove the solenoid. Now see if the engine will start. If the engine starts, the shutoff solenoid either needs an adjustment or it is defective and replacement of the solenoid is necessary.

    Problem 3: Engine Misfires Or Runs Rough

    Probable Cause:

    1. Fuel Pressure Is Low
    Make sure there is fuel in the fuel tank. Look for leaks or bad bends in the fuel line between fuel tank and fuel transfer pump. Look for air in the fuel system. Check fuel pressure.

    If fuel pressure is lower than 170 kPa (25 psi) install a new filter element. The outlet pressure of the fuel transfer pump at full load must be 240 kPa (35 psi). If fuel pressure is still low, install a new fuel transfer pump.

    2. Air In Fuel System
    Find the air leak in the fuel system and correct it. If air is in the fuel system, it will probably get in on the suction side of fuel transfer pump.

    3. Leak Or Break In Fuel Line Between Injection Pump And Fuel Injection Nozzle
    Install a new fuel line.

    4. Wrong Valve Lash.
    Make adjustment according to the Subject, Valve Lash Setting.

    5. Defect In Fuel Injection Nozzle(s) Or Injection Pump(s)
    Run engine at rpm that misfires the most and runs the roughest. Then loosen a fuel line nut on the fuel injection nozzle for each cylinder, one at a time. Find the cylinder where a loosened fuel line nut does not change the way the engine runs. Test the injection pump and fuel injection nozzle for that cylinder. Install new parts where needed.

    6. Wrong Fuel Injection Timing
    Make adjustment to timing.

    7. Bent Or Broken Push Rod
    Replacement of push rod is necessary.

    8. Fuel Has "Cloud Point" Higher Than Atmospheric Temperature ("Cloud Point" = Temperature Which Makes Wax Form In Fuel).
    Drain the fuel tank, lines, and fuel injection pump housing. Change the fuel filter. Fill the tank with fuel which has the correct "cloud point" and remove the air from the system with the priming pump.

    Problem 4: Stall At Low RPM

    Probable Cause:

    1. Fuel Pressure Is Low
    Make sure there is fuel in the fuel tank. Look for leaks or bad bends in the fuel line between fuel tank and fuel transfer pump. Look for air in the fuel system. Check fuel pressure.

    If fuel pressure is lower than 170 kPa (25 psi) install a new fuel filter element. The outlet pressure of the fuel transfer pump at full load must be 240 kPa (35 psi). If fuel pressure is still low, install a new fuel transfer pump.

    2. Idle RPM Too Low
    Make adjustment to governor so idle rpm is the same as given in the TMI (Technical Marketing Information) or Fuel Setting And Related Information Fiche.

    3. Defect In Fuel Injection Nozzle(s)
    Install a new fuel injection nozzle.

    4. Engine Accessories
    Check engine accessories for damage and correct adjustment. If necessary, disconnect the accessories and test the engine.

    5. Defect In Fuel Injection Pump(s)
    Install new parts if needed.

    Problem 5: Sudden Changes In Engine Speed (rpm)

    Probable Cause:

    1. Failure Of Governor Or Fuel Injection Pump
    Look for damaged or broken springs, linkage or other parts. Remove the governor. Check for free travel of fuel rack. Be sure fuel injection pumps are installed correctly. Check for correct governor spring. Install new parts for those that have damage or defects.

    Problem 6: Not Enough Power

    Probable Cause:

    1. Poor Quality Fuel
    Remove the fuel from the fuel tank. Install a new fuel filter element. Put a good grade of clean fuel in the fuel tank.

    2. Fuel Pressure Is Low
    Make sure there is fuel in the fuel tank. Look for leaks or bad bends in the fuel line between fuel tank and fuel transfer pump. Look for air in the fuel system. Check fuel pressure.

    If fuel pressure is lower than 170 kPa (25 psi) install a new fuel filter element. The outlet pressure of the fuel transfer pump at full load must be 240 kPa (35 psi). If fuel pressure is still low, install a new fuel transfer pump.

    3. Leaks In Air Inlet System
    Check the pressure in the air inlet manifold. Look for restrictions in the air cleaner.

    4. Governor Linkage
    Make adjustment to get full travel of linkage. Install new parts for those that have damage or defects.

    5. Wrong Valve Lash
    Make adjustment according to the Subject, Valve Lash Setting.

    6. Defect In Fuel Injection Nozzle(s) Or Fuel Injection Pumps
    Run engine at rpm that misfires the most or runs the roughest. Then loosen a fuel line nut on the injection pump for each cylinder, one at a time. Find the cylinder where a loosened fuel line nut does not change the way the engine runs. Test the injection pump and fuel injection nozzle for that cylinder. Install new parts where needed.

    7. Wrong Fuel Injection Timing
    Make adjustment to timing.

    8. Rack Setting Too Low
    Make reference to the TMI (Technical Marketing Information) or Fuel Setting And Related Information Fiche.

    9. Defect In Aftercooler
    Check temperature of inlet and outlet water supply. Remove any external or internal restrictions.

    10. Fuel Ratio Control
    Control either needs an adjustment or it is damaged and a new control is needed.

    11. Turbocharger Has Carbon Deposits Or Other Causes Of Friction
    Make inspection and repair of turbocharger as necessary.

    Problem 7: Too Much Vibration

    Probable Cause:

    Probable Cause:

    1. Poor Quality Fuel
    Remove the fuel from the fuel tank. Install a new fuel filter element. Put a good grade of clean fuel in the fuel tank. See Diesel Fuels and Your Engine, SEBD0717.

    2. Defect In Fuel Injection Nozzle(s)
    Install new fuel injection nozzle(s).

    3. Defect In Fuel Injection Pump(s)
