Marine diesel engines. Operator’s manual
Maintenance task. Fuel level inspection
Periodically, it is necessary to check the fuel level to assure the operation of the engine. On
top of that, if fuel pump sucks air when the fuel level is lower than pump suction, it could break.
Whenever possible, keep the fuel tank full. The temperature changes may cause
condensation of the damp air present in the tank and this water accumulates at the bottom. It can
cause an increase of corrosion or an impossibility of starting the engine if this water is aspired by the
fuel pump.
Maintenance task. Fuel tank clean
The fuel impurities could obstruct the suction pump. For this reason, drain out the content of
the fuel tank to remove condensate and any foreign material. Then, wash the tank with fuel and refill
it.
Maintenance task. Water separator filter purge
The fuel system has to have a water separator filter (supplied as accessory) to avoid the inlet
of water in the fuel circuit. According to the maintenance plan it is necessary to purge the filter to
eliminate water periodically. This is the procedure:
1.
Loosen the bottom nut to eliminate water.
2.
Shut it off again.
3.
Check for any leakage.
Maintenance task. Fuel filter change
Procedure to change the fuel filter:
1.
Remove fuel filter with a belt
wrench.
2.
3.
Place a new fuel filter and firmly
tighten it with the hand.
4.
Prime the system.
5.
When this operation is finished,
start the engine and check that it is not leaking.
Wash hands after any contact with diesel fuel.
Maintenance task. Injection pump inspection
The injection pump is adjusted at factory and should never be adjusted carelessly. Such
adjustment, whenever is required, shall be made by a SOLÉ DIESEL licensed service shop, since a
precision pump monitor and skill knowledge are required.
You must check:
-
The presence of exhaust smoke color.
Procedure: quickly accelerate engine.
Criteria: no remarkably black smoke exhaust, and correct function of fuel cut-off solenoid
-
Any leaks at the body injection pump or fuel lines.
