ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 8HY 8HV
B1EP18YD
Checks (continued).
Refit the screw (8).
Rotate the crankshaft six times
(clockwise).
IMPERATIVE: Never rotate the engine backwards.
Peg:
The camshaft, using tool
[2](oil the pegs).
The fuel high pressure pump pulley (14), using tool [3]at «c».
WARNING:The magnetic track should show no signs of damage and should not be
approached by any source of magnetism.
Peg the crankshaft at
«b», using tool [3].
IMPERATIVE:Should it be impossible to peg the camshaft, check that the
offset between the hole in the camshaft pinion and the pegging hole is not
greater than 1 mm.Otherwise repeat the operation to position the timing belt
(see corresponding
operation)

Setting the timing (continued).
Chec
ks (continued).
Reposition the timing belt, belt at «e»well tensioned, in the following order:
Guide roller
(17).
Camshaft pulley
(16).
Fuel high pressure pump pulley
(15).
Coolant pump pinion
(18).
Tensioner roller
(19).
Remove the
5 mmdiameter peg at «d».
Adjusting the fitting tension of the belt.
Action the tensioner roller (19)to align the marks «f»and «g», avoiding detensioning the timing belt,
with the aid of a male hexagonal spanner, at
«c».
If this is not successful, repeat the operation to tension the belt.Hold the tensioner roller in position
(19).
Tighten the tensioner roller, tightening to
3,7 ±0,3 m.daN.
Check the position of the tensioner roller
(the alignment of the marks «f»and «g»should be correct).
Remove tools
[2]and [3].
Turn the crankshaft
six rotations(clockwise).

SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Engines: HDi ALL TYPES
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 (1350 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.
