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 anti-clockwise direction, to obtain: 63 SEEMunits.
Tighten the roller (2)to 2 m.daN.
Tighten the six screws (5)to 1 m.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.

ENGINECHECKING AND SETTING THE VALVE TIMING
Engine: NFU
Adjusting the fitting tension of the timing belt.
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 «e».
WARNING: The index «c» must not go beyond the notch «e». If it should do this, restart the
timing belt tensioning operation.
Hold the tensioner roller in this position with the aid of a hexagonal spanner.
Tighten the tensioner roller fixing nut to 2.2 ± 0.2 m.daN.
IMPERATIVE: The tensioner roller must not rotate during the tightening of its fixing. If it
does, restart the timing belt tensioning operation.
Refitting.
Refit the timing covers, the crankshaft pulley, the auxiliaries drive belt
(see corresponding operation).
Complete the refitting.
IMPERATIVE: Carry out the operations that are necessary following a reconnection of the
battery
(see corresponding operation).
