Remove the engine support assembly (9), the fixing
screw (8)and the lower cover (7).
Slacken the nut (11).
Fully detension the belt by moving the tensioner
roller (10).
Remove the timing belt.
IMPERATIVE: Check that the tensioner roller
turns freely
(no tight spot).
Refitting.
Position the
(new)timing belt, in the following
sequence:
- The inlet camshaft pulley, the exhaust camshaft
pulley, the guide roller, the crankshaft pulley, position
the tool [4], the coolant pump pulley, the dynamic
tensioner roller.

CHECKING AND SETTING THE VALVE TIMING
Engine: NFU
Refitting.
Fit the
(new)timing belt in position, in the following order:
- Inlet camshaft pulley, exhaust camshaft pulley, guide roller, crankshaft pulley, position tool [5],
coolant pump pulley, dynamic tensioner roller.
Remove tools [1], [2a], [2b]and [4].
Overtension on the belt.
Turn the tensioner roller (7)with the aid of a hexagonal spanner at «a».
Bring the index «c»to position «d», to tension the belt to the maximum of the interval indicated.
Hold the tensioner roller, using tool [4].
Tighten the fixing nut of the tensioner roller, tightening to 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 pegs [1], [2a]and [2b].
Remove the pegs [1], [2a], [2b]and[4].
