Check of fuel system
The check must be executed both when the engine
disconnected and when it is running.
The check operation consists in examining the fuel pipelines
running from the tank to the pre-filter (if provided in the
specific equipment), to the filter, to the injection pump and to
the injectors.
Cooling system check
The check must be executed both when the engine
disconnected and when it is running.
Check the pipelines from the engine to the radiator, from the
expansion tank and vice-versa. Find out any blow-by, verify the
status of the pipes specially close to the holding strips.
Verify that the radiator is clean, the correct working of the fan
flywheels, the presence of any leakage from the connectors,
from the manifold and from the radiating unit.
Due to the high temperatures achieved by the
system, do not operate immediately after the engine’s
disconnection, but wait for the time deemed
necessary for the cooling.
Protect the eyes and the skin from any eventual high
pressure jet of cooling liquid.
Lubricating system check
The check must be executed both when the engine
disconnected and when it is running.
Verify the presence of any oil leakage or blow-by from the
head, from the engine pan of from the heat exchanger.
The engine oil is highly polluting and harmful.
In case of contact with the skin, rinse well with water
and detergent.
Adequately protect the skin and the eyes, operate in
full compliance with safety regulations.
Disposal must be carried out properly, and in full
compliance with the law and regulations in force.
Check of water presence within fuel filter or pre-filter
The components of the system can be damaged
very quickly in presence of water or impurity within
the fuel.
Timely proceed operating on the pre-filter (not
available on the engine block) to carry out the
drainage of the water within the feed circuit.
The coolant should be checked every year before the winter,
assessing the density and it should be changed every two years.
In case of new filling, proceed bleeding system,
through the bleeds on the engine.
If bleeding of the system is not carried out, serious
inconvenience might be caused to the engine due
to the presence of air pockets in the engine’s head.
There is a bleed screw at the base of the fuel filter for draining
any water in the filter.
Place a container underneath the filter and slightly loosen the
screw. Drain the water eventually contained in the filter’s
bottom.
Lock the screw (max 0.5 Nm locking couple) as soon as fuel
starts bleeding.
