SP8-10. FUEL FILTERS (Continued)
a. Turn off the fuel.
b. Open the filter drain plug
(Figure 14-A)
and drain
the filter.
Figure 14: Secondary Fuel filter
c. Remove the secondary fuel filter by turning the
filter clamp
(Figure 14-B)
counter clockwise until
the filter cartridge
(Figure 14-C)
slides out.
NOTE: Before installing a new filter cartridge make sure
the surfaces where the cartridge comes in contact with the
mounting plate are absolutely clean. Dirt can be washed
into the fuel injection system. This may result in severe
damage to the fuel injection pump or nozzles. Your
generator set may have two secondary filters, depend
-
ing on the fuel supply system. Do not “prefill” the new
fuel filter as the fuel used may be contaminated and
damage the fuel system components.
d. Install new filter cartridge.
e. Turn on the fuel.
BLEEDING THE FUEL SYSTEM
CAUTION: Escaping diesel fuel under pressure
can penetrate the skin, causing serious personal
injury. Before disconnecting lines be sure to
relieve all pressure. Before applying pressure to
the system be sure all connections are tight and
the lines, pipes and hoses are not damaged. Fuel
escaping from a very small hole can be almost
invisible. Use a piece of cardboard or wood rather
than the hands to search for suspected leaks. If
injured by escaping fuel, see a doctor at once.
Serious infection or reaction can develop if proper
medical treatment is not administered immediately.
1. Whenever the fuel system has been opened for service,
(lines disconnected, filter changed, etc.) it will be
necessary to bleed air from the system.
a. To bleed the fuel system, loosen the bleed plug
(Figure 14-D)
on the fuel filter.
Operate the primer pump lever on fuel transfer
pump (see component locations) until most of the
air bubbles are expelled and clear fuel escapes the
bleed plug. Tighten the bleed plug.
b. If the engine will not start, it may be necessary to
loosen the fuel supply pipe at the pump. Operate
primer lever of fuel supply pump until fuel flow
is free from air bubbles. Retighten fuel supply
line to 22 ft. lb. (30 N•m).
c. If engine still doesn't start, loosen fuel line
connection at injection nozzle. Always use a back
up wrench when loosening or tightening fuel lines
at nozzles and injection pump to avoid damage.
With throttle on full, crank the engine over with
the starter until fuel without air flows from the
loose fuel pipe connection. Repeat procedure for
remaining nozzles, if necessary, until engine
starts or until air has been removed from system.
Tighten the connections to 20 foot lb. (27 N•m).
d. For models M1066A2 and M1066A3 bleed the fuel
system using the electronic transfer pump. The
ignition should be on and allow 40 seconds for the
pump to complete the priming. If additional system
bleeding is needed, do it by loosening the fuel line
connections at the injection nozzles.
SP11. INJECTORS
1. Fuel injectors should be checked by a Lugger-Northern
Lights dealer or qualified fuel injection shop every 500
hours.
2. Injector Removal:
You will need the following special tools:
JDE38A-Injection Nozzle Puller
JDE39-Nozzle Bore Cleaning Tool, JD258-Pilot Tool
a. Before removal, carefully remove all dirt from
the cylinder head around fuel injection nozzles.
Clean with compressed air to prevent dirt from
entering the cylinders or valve seats. Plug the
bore in the cylinder head after each fuel injection
nozzle has been removed. Cap fuel line openings
as soon as they are disconnected.
b. Immediately fit protective caps over the nozzle
tips and the line connections to avoid handling
damage.
