Information:
Final Fuel Filter
The filter element collects and holds contaminants and cannot be washed or otherwise restored.To remove the used filter, proceed as follows:1. Stop the engine and close the diesel fuel line valve (if equipped).2. Unscrew and remove filter. 3. Clean the gasket sealing surfaces on the filter bases. 4. Lubricate the new filter gasket with clean diesel fuel.
Do not pour fuel into the new filter element before installing. Prime the system as instructed in the topic, PRIMING THE FUEL SYSTEM.
5. Tighten the filter by hand until the gasket contacts the base, then tighten 1/2 to 3/4 turn more.6. Start the engine and run at 1000 rpm for several minutes and check for leaks. If the engine fails to start, prime the fuel system. See the topic TO PRIME THE SYSTEM. Keep New Fuel Filters On Hand
Extra filters should be kept on hand for replacement. Always keep filters wrapped in their original carton to insure against dust and dirt accumulation which will shorten the life of the filters or may cause damage to the fuel injection equipment.To Prime The System
If air is trapped in the fuel system, the diesel engine will either not start, or will misfire. Then it is necessary to prime the system.The fuel priming pump is mounted on the fuel filter base. If the fuel filter is changed or if the engine has run out of fuel, prime the fuel system as follows: 1. Be sure the fuel line valve is open and the engine shutoff control is off.2. Unlock the fuel priming pump.3. Operate priming pump until increased resistance is felt.4. Lock fuel priming pump.If the engine fails to start or continues to misfire or smoke, further bleeding is necessary. With engine running, or with the use of the priming pump, loosen fuel line nuts, one at a time, several times in succession and allow fuel to run until free of air bubbles. Tighten fuel line nuts.
LOOSENING FUEL INJECTION LINE TO BLEED SYSTEMFuel Injection Equipment
When improper fuel injection is affecting engine operation, a systematic check should be made to determine the cause. The most likely cause is dirt or water in the fuel. Drain the sediment from the fuel tank. Check the fuel pressure gauge as mentioned in the topic, FUEL FILTERING SYSTEM. Replace the filters if necessary. Then prime the fuel system until clean fuel reaches the fuel injection pumps. If the fuel system is air bound, priming the system will overcome the difficulty.If the engine is running irregularly, smoking, or knocking, a fuel injection valve may not be spraying the fuel properly.Direct Injection System
The fuel system of direct injection engines is essentially the same as precombustion chamber engines. The absence of the precombustion chamber requires a different fuel nozzle and adapter. Externally the direct injection fuel nozzle resembles the precombustion chamber nozzle except it is longer in length. Nozzle testing and replacement procedure is the same as illustrated for the precombustion chamber engines, except that an extracting tool is used to remove
