SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Safety requirements.
Preamble.
All interventions on the injection system must be carried out to conform
with the following requirements and regulations:
- Competent health authorities.
- Accident prevention.
- Environmental protection.
WARNING: Repairs must be carried out by specialised personnel
informed of the safety requirements and of the precautions to be
taken.
Safety requirements.
IMPERATIVE: Take into account the very high pressures in the high
pressure fuel circuit (1600 bars), and respect the requirements
below:
- No smoking in proximity to the high pressure circuit when work is being
carried out.
- Avoid working close to flame or sparks.
Engine running:
- Do not work on the high pressure fuel circuit.
- Always stay clear of the trajectory of any possible jet of fuel, which could
cause serious injuries.
- Do not place your hand close to any leak in the high pressure fuel circuit.After the engine has stopped, wait 30 secondsbefore any intervention.
NOTE:This waiting time is necessary in order to allow the high pressure
fuel circuit to return to atmospheric pressure.
Cleanliness requirements.
Preliminary operations.
IMPERATIVE: The technician should wear clean overall.
Before working on the injection system, it may be necessary to
clean the apertures of the following sensitive componen (refer to
corresponding procedures):
- Fuel filter.
- Fuel high pressure pump.
- Fuel high pressure common injection rail.
- Fuel high pressure pipes
- Diesel injector carriers.
IMPERATIVE: After dismantling, immediately block the apertures of
sensitive components with plugs, to avoid the entry of impurities.
Work area:
- The work area must be clean and free of clutter.
- Components being worked on must be protected from dust.

CHECKS: TURBO PRESSURE
Engine: DT17BTED4
Significant difference in pressure between the two turbochargers:
- Stop the engine.
- Remove the air filter with the two flowmeters.
- Mark the flowmeters "d"and "c".
- Remove both flowmeters.
Refit:
- Flowmeter "d"in place of flowmeter "c".
- Flowmeter "c"in place of flowmeter "d".
Start the engine.
Accelerate to 2500 rpm.
Compare the air flows (mg/stroke)from the two turbochargers:
- If the difference in air flow has changed turbochargers, replace the flowmeter that is faulty.
- If the difference in air flow is coming from the same turbocharger, check the condition of the air inlet
and outlet pipes of this turbocharger: replace or repair the parts that are faulty.
- If no anomaly is detected on the air inlet and outlet pipes of the turbocharger: replace the turbocharger.

DRAINING, FILLING AND TOPPING UP THE AM6 AUTOMATIC GEARBOX
Tool.
[1] Filling cylinder: (-).0340
Respect the safety and cleanliness requirements.
Draining.
IMPERATIVE: Draining of the gearbox must be done with the oil hot (60°C minimum), in order to
ensure that the impurities in suspension in the oil are eliminated.
NOTE:Drainage is only partial, as the torque converter cannot be drained totally.
Raise the vehicle.
Remove:
- The oil level plug (2)by means of the Torx spanner.
- The drain plug (1)using a hexagonalspanner.
NOTE :Around 3 litresof oil should flow out.
Filling.
Fit the drain plug (1)(with a new seal).
Tighten the plug (1)to: 5 ± 1 mdaN.
Remove:
- The air filter housing.
- The oil filler plug (3).
Use tool [1].

GEARBOX
TRANSMISSION
CHECKING THE OIL PRESSURE IN THE AM6 AUTOMATIC GEARBOX
Checking the torque converter.
WARNING: This check has to be of short duration (2 seconds), as it causes a rapid
rise in the temperature of the oil in the automatic gearbox.
Respect the following checking conditions:
- Engine at operating temperature.
- Gear lever in position D.
- Press on the brake pedal.
- Accelerate the engine to the maximum engine speed (see below).
Gear lever position.: D.
Maximum engine speed for ES9A : 2400 ± 50 rpm.
Maximum engine speed for DT17 : 2600 ± 50 rpm.
Diagnosis:
- If the maximum engine speed obtained is lower than the value indicated, the torque
converter is the cause.
- If the maximum engine speed obtained is higher than the value indicated, the automatic
gearbox is the cause (slipping).
Additional operations.
Remove tools [1]and [2].
Refit the screw (2), with a new seal.
Reposition the pipe (1).
Refit the air filter housing.
