Checking the timing.
Peg the flywheel, using tool [1].
Peg the camshaft pulley, using tool [2].
Setting the timing.
NOTE:Remove the sparking plugs, to ease rotation of the crankshaft.
Rotate the engine by means of the crankshaft screw (1).
Peg the camshaft pinion.
Peg the flywheel
Slacken the nut (2).
Fullt detension the belt by acting on the tensioner roller.
Remove the belt.
IMPERATIVE: Check that the tensioner roller turns freely
(no tight spot).

ENGINECHECKING 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"well-tensioned 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).
Pre-tensioning the belt.
Place tool [4] on the tensioned part "b"of the belt.
Slacken the screw (2).
Turn the roller (3)in the anti-clockwise direction using the drive square, to obtain a value of: 44 SEEMunits.
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.
