ENGINECHECKING AND SETTING THE VALVE TIMING
Engine: NFU
Setting the valve timing.
Loosen the screw (2), remove the belt.
Loosen the six pulley screws (1)on the hubs
(there should be a slight amount of friction between the screws and
the pinions).
Check that the rollers (2)and (3) rotate freely.
NOTE: The belt bears three identification marks (a), (b)and (c), facing its own teeth (1), (52)and (72)respectively
(identification marks = white paint lines on the back of the belt facing the corresponding teeth).
Refit the belt.
Line up mark (A)on the belt with groove (D)of the pinion (4).
Hold the belt against the pinion (4).

ENGINECHECKING AND SETTING THE VALVE TIMING
Engine: NFU
Setting the valve timing.
Remove the tools [1], [2], [3]and [4].
Rotate the engine by four turnsin the normal direction
(do not turn backwards).
Peg the flywheel [2].
Loosen the six screws (5), while ensuring there is still a slight amount of friction with the pulley.
Peg the camshaft hubs using pegs [3]and [4].
WARNING: In certain cases, it may be necessary to slightly turn the camshaft using the hub fixing screw.
Fit the tool [1].
Loosen the tensioner roller screw (2).
Rotate the roller (2)
(using tool [5])in an anti-clockwise direction to obtain: 37 SEEMunits.
Tighten the tensioner roller screw (2)to 2 m.daN.
Tighten the six pulley screws (1)to 1 m.daN.
Remove the tools.
