B:Engine:NFU.
Turn the tensioner roller
(7)with the aid of a hexagonal spanner at «a».
Bring the index
«c»to position «f», to tension the belt to the maximum of the
interval indicated.Hold the tensioner roller
(7), using tool [4].
Tighten the fixing nut of the tensioner roller, tightening to
1 ± 0,1 m.daN.
Turn the crankshaft by
4 rotations(normal direction of rotation).
IMPERATIVE: Never make the crankshaft rotate backwards.
Make sure that the timing is correctly set by refitting the tools [1], [2]and [3].
Remove the tools

Adjusting the fitting tension of the timing belt.
A:Engine:HFX – KFV.
B:
Engine:NFU.
Slacken the nut while maintaining the position of the tensioner roller, with the aid of
a hexagonal spanner at
«a».
Next bring the index
«c»to its adjusting position «a».
The index
«c»should not go beyond the notch «g».
WARNING:The index«c» must not go beyond the notch«g».If it should do this,
restart the timing belt tensioning operation.
Hold the tensioner roller
(7)in this position, with the aid of a hexagonal spanner.
Tighten the tensioner roller fixing nut to :
2 ±0.2 m.daN.(HFX - KFV engines)
2.2 ± 0.2 m.daN.(NFU engine)
IMPERATIVE: The tensioner roller must not rotate during the tightening of its
fixing. If it does, restart the timing belt tensioning operation.
Complete the refitting.

CHECKING AND SETTING THE VALVE TIMING
Engines: KFW NFV
Refitting the timing belt.
NOTE:
Check that the pegs [1]and [2]are in place.
WARNING: Respect the direction of fitting of the belt: The arrows "a" indicate the direction of rotation of
the crankshaft.
Position:
The timing belt, belt "b"welltensioned, in the following order:
Crankshaft pinion, camshaft pulley, coolant pump pulley, tensioner roller.
Tool
[5](respect the direction of fitting relative to the valve timing).
Put the tensioner roller in contact with the belt.
Tighten the nut
(2).
Pretensioning the belt.
Place tool [4]on the tensioned part "b"of the belt.
Slacken the screw (2).
Turn the roller (3)in the anticlockwise direction using the drive square, to obtain a value of:44 SEEM units. Tighten the nut (2)to 2 m.daN. Remove tools [1], [2]and [4].
Rotate the crankshaft 4 turnsin the normal direction of rotation.
IMPERATIVE:Never turn the crankshaft backwards.

CHECKING AND SETTING THE VALVE TIMING
Engine: NFU
Setting the valve timing.
Turn the two pulleys (1)clockwise to the end of the slots.
With the belt strip (e)fully tensioned, place the belt over the pulley, first exhaust side, then inlet side, while
ensuring that marks (b)and (c)on the belt are aligned with marks (f)on the pulleys.
Hold the belt in this position, and engage it over the water pump pinion and the tensioner roller.
Fit the tool
[1]on the belt at (e).
Rotate the roller (2) (using tool [5])in an anticlockwise direction, to obtain:63 SEEM units.
Tighten the roller (2)to 2 m.daN.
Tighten the six screws (5)to 1m.daN.
ESSENTIAL: Check that:
The camshaft pulleys (1) are not at the end of the slots (by removing a screw). The markings on the belt are aligned with the markings on the crankshaft and camshaft pulleys.
If not, repeat the setting procedure.
