Marine Diesel gensets. Operator’s Manual.
3.
Check for any leakage.
Maintenance task. Fuel filter change
Procedure to change the fuel filter:
1.
Close the fuel supply valve.
2.
Disconnect fuel pipes from the fuel filter.
3.
Remove fuel filter with a bell key.
4.
Place a new fuel filter.
5.
Reconnect fuel pipes from the fuel filter.
6.
Open the fuel supply valve.
7.
Once finished with this operation, start the genset and check for oil leaks.
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 colour.
-
Procedure: quickly accelerate genset.
Criteria: no remarkably black smoke exhaust, and correct function of fuel cut-off solenoid
-
Any leaks at the body injection pump or fuel lines
Maintenance task. Injector inspection
To check the injection pressure of injectors
(opening pressure) you have to follow these steps:
1.
Remove nozzle and washer.
2.
Install the injection nozzle on the tester. Slowly
operate the tester handle full strokes to bleed
(remove) air from the pipe and nozzle.
3.
Make a slow increase in pressure by operating the
tester handle at a speed of more than one stroke per second while observing the pressure gauge.
4.
The pressure gauge reading will slowly increase and, when the nozzle starts discharging fuel, it
will go down fast. Take the gauge reading right then as the injection pressure.
5.
To adjust the injection pressure, increase or decrease the amount of shims fitted to the nozzle
holder.
Injection pressure
13,73 MPa (140 kgf/cm2)
