CHECKING AND SETTING THE VALVE TIMING
Engine: DT17BTED4
Reposition the timimg belt, strip «j»well tensioned, in the following order:
- Guide roller (19).
- Camshaft pulley (18).
- Guide roller (16).
- Camshaft pulley (23).
- Tensioner roller (20).
NOTE:If necessary, turn the pulleys (23)and (18)slightly anti-clockwise (the offset must not be
more than one tooth).
Remove the tool [4].
Using a hexagonal spanner, rotate the tensioner roller (20)anti-clockwise.
Position the index "l"facing the notch "k".
Tighten the screw (21) : 2,5 ± 0,2.
Remove the screws (15)and (17)from the pulleys (23)and (18)in order to check that the screws
(15)and (17)are not at the end of slots.

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.

- The ECU when the ignition is switched on.
Before reconnecting a switch, check:
- The condition of the various contacts (for deformation, corrosion etc.)
- The presence and condition of the mechanical locking.When performing electrical checks:
- The battery should be correctly charged.
- Never use a voltage source higher than 16V.
- Never use a test lamp.
Repairs on mechanical components.
Never place the gearbox on the ground without protection.
Do not use the unions on the gearbox as handles for moving the
gearbox.
It is imperative
that the converter retaining peg should be in place
when removing the gearbox.
It is imperativeto use the centring pegs to couple the gearbox on the
engine.
Remove the converter retaining peg before coupling the gearbox on
the engine.
