Marine Diesel gensets. Operator’s Manual.
6.
Look at the orifice discharge pattern (shape of discharge) when
fluid begins to flow through the injection nozzle. The discharge
must be finely and uniformly atomized. Any change is an indication
of a bad nozzle.
7.
If the nozzle is bad, remove the tip from the nozzle and wash needle
valve and body in clean washing solution.
And if the nozzle is still bad after the tip has been washed, replace
the tip.
8.
When installing the new tip, remove synthetic resin film from the tip
and slide the needle valve in the body in clean Diesel fuel to wash
off inhibitor completely
9.
The washer shown on figure must be replaced.
When testing the injection nozzle, keep its tip pointed away from the operator. Fuel from the
orifices in the tip of the nozzle is under high pressure and can cause injury to the operator.
Maintenance task. Bleeding air from the fuel system
Prime the fuel system to bleed the air from the circuit. Trapped air in the fuel system can
cause difficult starting and erratic engine operation. It is necessary to prime the system:
✓
Before starting the engine for the first time.
✓
After running out of fuel and adding fuel to the tank.
✓
After fuel system maintenance such as changing the fuel filter, draining the fuel/water
separator, or replacing a fuel system component.
Fuel filter:
1.
Loose the air drain plug on the fuel filter, turning it approximately
1,5 laps.
2.
Unlock the fuel pump plunger turning it in anticlockwise and
actuate the pump.
3.
Taut the air drain plug when fuel flows without fizzing.
Fuel injection pump:
1.
Loose the air drain plug on the fuel filter, turning it
approximately 1,5 laps.
2.
Unlock the fuel pump plunger turning it in anticlockwise
and actuate the pump.
3.
Taut the air drain plug when fuel flows without fizzing.
When fuel overflows from the injection pipes, wipe thoroughly with a cloth. Spilled fuel is a fire
hazard.
