Lubrication System Oil Selection Oil Check The selection of engine oil is very important to a diesel Check crankcase oil level daily or before each start to engine. If an unsuitable oil is used or an oil change is ensure that the level is in the safe range. To check oil neglected, damage and a shorter engine life may result.
Oil Change On a new engine, change the oil after the first 50 hours of operation and thereafter at 100-hour intervals or 3 months, whichever occurs first. Change oil more frequently under dirty, dusty conditions. Change oil while the engine is still warm. 1.
Oil Filter 1. Loosen oil filter by turning with a filter wrench in a counterclockwise direction. Use rags to clean up Replace the oil filter for the first time after 50 hours or spilled oil. Remove and discard. 1 month of operation and then every 100 hours or 2.
Fuel System Specification Fuel Filter Use a clean, good quality No. 2-D (DIN 51 601) diesel The fuel filter serves to remove water and dirt contained fuel oil. The fuel must meet the requirements of the in the fuel. The fuel filter element is paper and no American Society of Testing and Materials (ASTM) attempt should be made to clean it.
Bleeding the Fuel System Draining fuel system. Explosive fuel vapors can cause severe injury or death. Spilled fuel can cause If the generator set engine runs out of fuel, air leaks an explosion. Use a container to catch fuel when develop in the suction side of the fuel system, or the fuel draining fuel system.
Fuel Solenoid The fuel solenoid (Figure 3-8) stops fuel flow through the fuel injection pump when the start-stop/preheat switch is placed in the STOP position. If the fuel solenoid is removed or the setting is believed incorrect, readjust according to the following procedure. Do not modify the solenoid linkage during reconnection.
Governor frequency or in a clockwise direction to decrease speed. Tighten the lock nut to secure at new setting. The centrifugal, mechanical-type governor keeps the engine speed constant by automatically adjusting the amount of fuel supplied to the engine according to changes in the load.
Cooling System for remote radiator cooling system capacity. Drain WARNING petcocks are provided on the bottom tank of the radiator and another in the engine block to drain the system. When draining the coolant, remove the radiator cap and open the block drain located near the flywheel housing; this will allow the entire system to drain and prevent air pockets from forming and restricting coolant passage in Hot coolant and steam.

Consider thickness insulating sound-deadening material used to line the compartment when planning clearances. If necessary, enlarge the compartment maintain minimum clearance requirements. Securely fasten the generator set to avoid unwanted movement from vibration and road shock. If the unit is equipped with a mounting tray, the tray is usually supported on the ends by angle iron and has a full door for service access.
Air Requirements Each engine is equipped with a high water temperature shutdown switch automatically shuts down the set if operating temperatures climb too high. To prevent the generator set from shutdown, make sure the compartment openings are large enough to allow adequate circulation of the cooling and combustion air.
