ENGINECHECKING AND SETTING THE VALVE TIMING
Engines: 8HX 8HW 8HZ
B1EP18KC
Setting the timing (continued).
Turn the tensioner roller to the right to bring the index «c»to position «d», using a
hexagonal spanner.
Tighten the screw
(9)of the tensioner roller, tighten to 3 ± 0,3 m.daN.
Remove the tools [4]and [5].
Rotate the engine
ten times(check that the timing pinion is correctly up against the
crankshaft).
Check:
The pegging of the camshaft.
The crankshaft pinion.
The fuel high pressure pump pinion
(15).
The correct positioning of the index of the dynamic tensioner.
If these are not correct, repeat the operation to position the timing belt.Refit:
The engine speed sensor
(6).
The belt retaining stop (5), tighten to 0,7 m.daN.

PARTICLE FILTER SAFETY AND CLEANLINESS REQUIREMENTS
Operations on the fuel additive circuit.
IMPERATIVE: For all operations on the additive circuit, wear protective goggles and gloves that are resistant to hydrocarbons.
The work area must be ventilated.
In the event of any significant dispersion of additive:
Wear a breathing mask for filtering the particles.
Recover as much of the product as possible.
Place the product thus recovered in an appropriately labelled container. Wash the soiled area with copious amounts of water.
Dispose of materials and solid residues in an authorised recovery point.
IMPERATIVE:The filling kit should be recycled following a repair. All «Eolys» additive containers that have been opened should be
disposed of.
Cleanliness rules.
ESSENTIAL: The operator should wear clean overalls.
Before working on the injection circuit, it may be necessary to clean the unions of the following sensitive components(see corresponding operations).
Fuel filter.
Fuel high pressure pump.
Fuel high pressure regulator.
Fuel high pressure common injection rail. Fuel high pressure piping. Diesel injector carriers.
IMPERATIVE: After dismantling, immediately blank the unions of the sensitive components with plugs, to prevent any ingress of impurities.
