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.

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)

king the setting.
IMPERATIVE: Just prior to refitting, carry out the following tests.
Check that:
the rollers and the coolant pump operate freely
(no play and no tight spot).
there are no traces of oil
(from the crankshaft and camshaft sealing rings).
there is no leak of coolant fluid
(from the coolant pump).
the target track of the engine speed sensor
(14)is not damaged or scratched
(if necessary replace the defective components).
Refitting.
Fit the timing belt on the crankshaft pinion.
Position the belt on the guide roller, with the belt well tensioned.
Refit:
The timing protector
(13).

Reposition the timing belt, belt at «e»well tensioned, in the following order:
Guide roller
(17).
Camshaft pulley
(16).
Fuel high pressure pump pulley

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
