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.
