D4F 740, D4F 742, D4F 764 engine
D4F 784, D4F 786 engine
- Disconnect the petrol inlet pipe from the injector rail.
- Connect:
- the pipe (1) fitted with the pressure gauge contained
in the checking kit, with the " T " union (2) of
the (Mot. 1311-08),
- the " T " unionon the rail,
- the petrol inlet duct (3) to the " T " union.
- Start the engine.
- Determine the pressure.
- the pressure must be constant (3.5 bars).
- It may take a few seconds to obtain a correct injector
rail pressure reading.
- Stop the engine
FINAL OPERATION
- Disconnect:
- the petrol inlet duct from the " T " union,
- the " T " union from the rail.
- Connect the petrol inlet duct.
K4J or K4M
IMPORTANT
During this operation, be sure to:
- beware of fuel splashes when disconnecting the
union,
- protect sensitive areas from fuel outflow.
IMPORTANT
Wear goggles with side protectors for this operation.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this operation.
WARNING
Protect sensitive areas from fuel spillage.
CHECK
I - PREPARATION OPERATION FOR CHECK
- Ensure you have a checking tool (Mot. 1311-01) and
a " T " union (Mot. 1311-08).
II - TEST OPERATION
K4M
- Disconnect the fuel supply union from the injector
rail.
- Connect:
- the pipe fitted with a test pressure gauge (Mot.1311-01) with the "
T " union (Mot. 1311-08) (1),
- the " T " union (Mot. 1311-08) to the injector rail,
- the injector rail fuel supply union to the " T " union
(Mot. 1311-08).
K4J
- Disconnect the fuel supply union from the injector
rail.
- Connect:
- the pipe fitted with a test pressure gauge (Mot.1311-01) with the "
T " union (Mot. 1311-08) (2),
- the " T " union (Mot. 1311-08) to the injector rail,
- the injector rail fuel supply union to the " T " union
(Mot. 1311-08).
- Start the engine.
- Record the pressure; this should be constant at 3.5
bar.
Note:
It may take a few seconds to obtain a correct
injector rail pressure reading.
III - FINAL OPERATION
- Disconnect the " T " union (Mot. 1311-08) from the
injector rail.
- Separate the test tool (Mot. 1311-01) from the " T "
union.
- Connect the fuel supply pipe union on the injector
rail.
M4R
IMPORTANT
During this operation, it is essential to:
- beware of fuel splashes when disconnecting the
union,
- protect sensitive areas from fuel outflow.
IMPORTANT
Wear goggles with side protectors for this operation.
IMPORTANT
Wear gloves during this operation.
- Disconnect fuel supply pipe union (1) on the injector
rail.
- Connect:
- the pipe (2) attached to the trolley pressure gauge
(Mot. 1311-01) with a " T " union (3) (Mot. 1311-
08),
- the " T " union to the injector rail,
- the injector rail fuel supply union to the " T " union.
- Note the fuel pressure.
- The fuel pressure must be constant (3.5 bar +-
0.06).
- It may take a few seconds to obtain a correct injector
rail pressure reading.
F4R
IMPORTANT
During this operation, be sure to:
- beware of fuel splashes when disconnecting the
union,
- protect sensitive areas from fuel outflow.
IMPORTANT
Wear gloves during this operation.
IMPORTANT
Wear goggles with side protectors for this operation.
I - REFITTING PREPARATION OPERATION
BEFORE CHECK
- Use the (Mot. 1311-01) and the (Mot. 1311-08).
- Assemble the long flexible pipe of the (Mot. 1311-
01) and the (Mot. 1311-08).
- Disconnect the fuel supply union on the injector rail.
- Pass the flexible pipe of the (Mot. 1311-01) fitted
with the (Mot. 1311-08) under the inlet manifold.
- Connect:
- the (Mot. 1311-08) onto the injector rail positioning
it between the rocker cover and the inlet manifold
then pivoting it,
- the fuel supply union on the (Mot. 1311-08),
- the fuel pressure gauge on the flexible pipe.
II - FUEL PRESSURE CHECK
- Switch on the ignition.
- Measure the fuel pressure.
- The value should be 3.5 bar +-0.2.
Note:
It may take a few minutes to obtain the correct
pressure value.
III - FINAL OPERATION
- Disconnect the fuel supply union on the (Mot. 1311-
08).
- Disconnect:
- the (Mot. 1311-08) from the injector rail,
- the fuel pressure gauge on the flexible pipe.
- Remove the flexible pipe of the (Mot. 1311-01) fitted
with the (Mot. 1311-08).
- Separate the (Mot. 1311-01) from (Mot. 1311-08).
- Connect the fuel supply union on the injector rail.
