3.0 ENGINE SYSTEMS
3.1 FUEL SYSTEM
3.1.1 Bleeding the Fuel System
CAUTION: Escaping fluid under pressure can
penetrate the skin causing series injury. Relieve
pressure before disconnecting fuel or other lines.
Tighten all connections before applying pressure.
Keep hands and body away from pinholes and
nozzles, which eject fluids under high pressure.
Use a piece of cardboard or paper to search for
leaks. Do not use your hand.
If ANY fluid is injected into the skin, it must be
surgically removed within a few hours by a doctor
familiar with this type injury or gangrene may
result. Doctors unfamiliar with this type of injury
may call the Deere & Company Medical
Department in Moline, Illinois, or other
knowledgeable medical source. Ref figure #10
Whenever the fuel system has been opened up for
service (lines disconnected or filters removed), it will
be necessary to bleed air from the system.
If engine will not start, it may be necessary to bleed
air from fuel system at fuel injection pump or
injection nozzles as explained next.
3.1.2 Changing the Fuel Filter
It may also be necessary to change filters out with the
recommendations in the event of:
1) The engine has had an overhaul.
2) The quality of the fuel is questionable.
3) The engine has been subjected to temporary
adverse conditions outwith it normal
operating parameters.
4) The fuel tank condensation trap has not been
drained in line with manufacturer’s
recommendations.
3.1.3 Fuel Tanks
Keep the fuel tank filled to reduce condensation to a
minimum. Open drain at the bottom of the fuel tank
once a week to drain off any possible water and/or
sediment. Fill tank after each test run.
3.2 AIR/EXHAUST SYSTEM
3.2.1 Ambient Conditions
Clarke engines are tested in accordance with SAE
J1349 (Clarke USA) or ISO 3046 (Clarke UK). In
this capacity they may be derated to meet certain site
conditions, failure to do so can seriously impede the
performance of the engine and could lead to
premature failure.
3.2.2 Ventilation
The engine must be provided with adequate
ventilation to satisfy the requirements of the
combustion system, radiator cooling systems where
fitted, and allow adequate dissipation of radiated heat
and crankcase emissions. For all this data refer to
Installation & Operation Data. This data can be used
for proper sizing of inlet and outlet louvers.
3.2.3 Standard Air Cleaner
Should a situation occur where the air cleaner
becomes plugged with dirt (starving the engine of
air), loss of power and heavy black smoke will result;
the air cleaner should be replaced immediately.
CAUTION: Do not attempt to remove the air
cleaner while an engine is running nor run the engine
while the air cleaner is off. Exposed components
could cause severe injury to personnel and major
internal engine damage could occur should any
foreign matter be drawn into the engine.
3.2.4 Crankcase Ventilation
3.2.4.1 Open Crankcase Ventilation
Vapors which may form within the engine are
removed from the crankcase and gear train
compartment by a continuous, pressurized ventilation
system.
A slight pressure is maintained within the engine
crankcase compartment. Vapors expelled through a
vent pipe.
