ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: KFW NFV
Pretensioning the timing belt (continued).
Make sure of the timing setting by refitting the pegs [1]and [2].
Remove the valve cover.
Position the tool
[5](respect the direction of fitting relative to the valve timing).
Adjusting the belt tension.
Place tool [4]on the tensioned part of the belt.
Slacken the nut (2).
Detension the belt, but too much.
Tension the timing belt to obtain a value of:
31 ± 2 SEEM units.
Tighten the nut (2)to 2 m.daN.
Remove tools [1], [2], [4] and [5].
Checking the belt tension.
Rotate the crankshaft 2 turnsin the normal direction of rotation.
Check that it is still possible to peg the following components. Flywheel.
Camshaft.
IMPERATIVE: Repeat the belt tensioning operation if the pegging is not possible.

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.
