Fuel Tank
Filling
Fill the day tank at the end of each day's operation. This helps prevent moisture in the air from condensing on the inside walls of the tank and contaminating the fuel with water.Draining Water And Sediment
1. Open the fuel tank drain valve and drain water and sediment from fuel tank.2. Close the drain valve.Fuel Filters
Checking Fuel Pressure Gauge
With engine running, the fuel pressure gauge should register in the NORMAL range. If the gauge registers in the OUT range, service the fuel filter elements.Draining Water And Sediment - All D342 and Early D353 Engines:
1. Close the fuel supply valve.2. Open the fuel vent valve, located on top of the fuel filter housing.
FUEL VENT VALVE3. Remove the fuel drain plug. Drain water and sediment from filter.
REMOVING FUEL FILTER HOUSING DRAIN PLUG - D342 Engine shown
REMOVING FUEL FILTER HOUSING DRAIN PLUG - D353 Engine shown4. Install the drain plug.5. Close fuel vent valve.6. Prime the fuel system.Cleaning Primary Filter Element
1. Stop the engine.2. Close the diesel fuel supply line valve.3. Loosen the nut on the cover and remove the case.
REMOVING PRIMARY FUEL FILTER4. Remove the filter element. Clean the element and case in clean diesel fuel or solvent.5. Inspect and install the upper and lower cover gaskets. Install new gaskets if necessary.6. Install the cleaned filter element and case.7. Open fuel supply line valve.8. Prime the fuel system.Installing New Final Fuel Filter Elements
D342 Engines:1. Close the fuel supply line valve.2. Open the fuel vent valve located on top of the fuel filter housing.3. Remove the drain plug and drain the fuel filter housing.4. Remove the filter housing cover.
REMOVING FILTER HOUSING COVER5. Remove the filter elements.6. Wipe sediment from inside the housings.7. Install the drain plug.8. Install the new elements.9. Inspect and install the cover gasket. Install a new gasket if necessary.10. Install the cover.11. Open fuel supply line valve.12. Prime the fuel system.D343 and Later D353 Engines:1. Close the fuel supply line valve.2. Open the fuel vent valve located on top of the fuel filter housing.3. Use a strap wrench to remove the filters. Be sure the old filter gasket does not remain attached to the filter base: Leaking between the new and old filter gaskets will result.
REMOVING FUEL FILTERS4. Wipe the filter base.
WIRING FILTER BASE5. Apply a few drops of clean fuel to the new filter gasket. Fill the new filter with clean diesel fuel.6. Tighten the filter by hand until the gasket contacts the base; then tighten the filter 1/2 turn more.7. Open the fuel supply line valve.8. Prime the fuel system.Earlier D353 Engines:Check the governor oil level by observing the oil level in the sight gauge. Add oil as necessary through the filler hole on top of the governor. See the Lubrication and Maintenance Chart for proper oil to use.1. Close the fuel supply line valve.2. Open the fuel vent valve located on top of the fuel filter housing.3. Remove the drain plug and drain the fuel filter housing.4. Remove the fuel filter housing.
REMOVE FUEL FILTER HOUSING5. Remove the filter elements.6. Wipe sediment from inside the housing.7. Install the drain plug.8. Install new elements.9. Inspect and install the cover gasket. Install a new gasket if necessary.10. Install the filter housing.11. Open fuel supply line valve.12. Prime the fuel system.Priming The Fuel System
1. Open the fuel supply line valve.2. Move the governor control lever to the shut-off position.3. Be sure the fuel vent valve, located on top of the fuel filter housing is open.4. Turn and unlock the priming pump knob. Operate the pump until a solid stream of fuel flows from the drain tube.
OPERATING FUEL PRIMING PUMP5. Turn the pump knob to the locked position.6. Close the vent valve.7. Start the engine.If The Engine Runs Rough, Release Trapped Air From Fuel Lines
With the engine running:1. Loosen a fuel line-loosen either the line nut at the fuel injection pump, or the line nut at the nozzle.
LOOSENING FUEL LINE NUT2. Allow the fuel to spurt until the fuel stream is free of air bubbles.3. Tighten the line nut. Proceed to the next fuel line and repeat the procedure.4. Continue this procedure for all fuel lines.Woodward UG8 Governor
Checking Governor Oil Level
1. Before starting the engine, the oil level should be at, or slightly above, the FULL mark.2. With the engine running, the oil level must be between the ADD and FULL marks. Do not overfill. See the Lubrication and Mainenance Chart for proper oil.
CHECKING OIL LEVELChanging Governor Oil
1. Move the governor control lever to the shut-off position.2. Shut off the fuel tank fuel supply valve.3. Disconnect the ground cable from the battery.
Be sure the engine cannot be started while work is being done. This is very important when the engine is equipped with an Automatic Start-Stop System.
4. Disconnect the governor linkage from the governor.5. Disconnect the governor synchronizing motor wires.
DISCONNECT SYNCHRONIZING MOTOR6. Remove the governor from the engine.7. Remove the governor cover.
REMOVING GOVERNOR COVER8. Turn the governor upside down and drain the oil.9. Flush the governor with clean diesel fuel or solvent.10. Install the governor on the engine.11. Fill the governor, with clean oil, to the FULL mark on the sight gauge. See Lubrication and Maintenance Chart for proper oil.12. Connect the governor linkage.
Before starting the engine, check to be sure the governor linkage has been connected to the governor.
