A replacement of fuel supply lines, fuel filters, fuel injection pump, high pressure fuel lines and injectors will let air enter the fuel system. Air in the fuel system will make the engine hard to start, run rough, misfire, and produce low power and cause excessive smoke and fuel knock. Replacing procedure of Air filter, Fuel filter of Generator: Replacing the fuel supply lines, fuel filters, fuel injection pump, high presser fuel lines and injectors will let air enter into the fuel system. One must follow the system to bleed the air from the system. Since the fuel transfer pump provides positive pressure through the fuel filter and supply line to the fuel injection pump, loose connections or defective seals show as a fuel leak and not as an air leak. For faster air purge small amounts of air can be bled from the fuel injection pump by operating the hand primer located on the fuel transfer pump or by cranking the engine. O...

What will bad Impact if Air in Fuel of Generator? Air in Fuel  Fuel is flammable. Keep all cigarettes, flames, pilot lights, arcing equipment and switches out to the work area and areas sharing ventilation to reduce the possibility of severe personal injury or death when working on the fuel system. Do not vent the fuel system on a hot engine this can cause to spill onto a hot exhaust manifold which can cause a fire.   How to bubble test of diesel generator fuel? The low pressure fuel system for diesel generator installation in the vehicle consists of the fuel tank lines between the tank and the engine transfer pump and lines and fuel filter and lines. Air or bubbles at the injection pump can cause the engine not to operate or erratic engine operation and subsequent  malfunction of the injection pump. Air can be introduced by leaks in the fuel system prior to transfer pump since the fuel in the lines in under a vacuum and can draw air in...

How one inspect Generator Vibration Damper and Viscous? Inspection procedure of Generator Vibration Damper and Viscous The silicone fluid in the vibration damper will become solid after extended service and will make the damper inoperative. An inoperative vibration damper can cause major engine or drivetrain failures.   Vibration Damper and Viscous Check the vibration damper for evidence of fluid loss, dents and   wobble. Inspect the vibration damper thickness for any deformation or raising of the damper cover plate. If any of those conditions are identified, contact your manufacturer and get solution or replace the vibration damper. Viscous damper have a limited life. The maximum damper life one get from operation and maintenance manual book.

How one inspects Vibration Damper and Rubber of Generator? Inspection procedure of Vibration Damper and Rubber of Diesel Generator Check by following picture firstly lines A in the vibration damper hub B and the inertia member C. If the lines are moiré than 1.59 mm= 1/6 inch out of alignment, replace the vibration damper. Inspect the rubber member for deterioration. If pieces of rubber are missing or if the elastic member is more than 3.18 mm= 1/8 inch below the metal surface, replace the damper. Look for forward movement on the damper ring on the hub. Replace the vibration damper if any movement is detected.

How one does properly Diesel Generator Cooling System Fill?   The system must be filled properly to prevent air locks. One must air vented during filling from the engine coolant passages. One must be open the petlock on the aftercooler for after cool engine. Wait about 2 or 3 minutes to allow air to be vented then add mixture to bring the level to the top. Cooling System Fill   The system has design fill rate of 19 liters = 5 gallon per minute. One must follow the caution *** Never use only water for coolant because water create corrosion. One must use mixture of 50 % water and 50 % propylene glycol or ethylene glycol antifreeze to fill the cooling system. Install the pressure cap. Operate the engine until it reaches at temperature of 80 degree Celsius = 180 F Must check the leaks for coolant. One should check the coolant level again to make certain the system is full of coolant or that the coolant l...

Valve adjustment should be done manufacturer recommended duration How one does valve adjustment of a generator? Remove he rocker lever covers. Locate the Top Dead Center for cylinder number 1 Use ½ inch drive and engine bearing tool to rotate the engine clockwise when facing the damper until cylinder number 4 for four cylinder engine or until cylinder 6 for six cylinder engine intake rocker arm starts to open the intake valve [Wiggle the rocker arm while barring the engine. When the rocker arm gets tight, stop barring] Adjust Valve of Diesel generator: The clearance is correct when some resistance is felt when the feeler gauge is slipped between the valve stem and the rocker lever. Intake Clearance: 0.254 mm= 0.010 inch             Exhaust Clearance: 0.508 mm=0.20 inch How one 4-cylinder Engine Valve adjusts? Four cylinder Engine Valve Adjust: On...
