Refit the screw (10).
Turn the crankshaft to bring the camshaft towards its pegging point.
Peg the camshaft at
«c», using tool [2](oil the pegs).WARNING: Do not press or damage the track of the engine speed sensor target
(13).
Peg the crankshaft at «e», using tool [3].
Remove:
The timing belt protector
(13).
The engine speed sensor (14).
Slacken the screw (15)of the tensioner roller, and keep it slackened using an allen
spanner at «d».
Detension the timing belt by pivoting the tensioner roller (clockwise).
Remove the timing belt, starting with the coolant pump pinion.
Checks.
ESSENTIAL: Just prior to refitting, proceed to the checks as below.
Check:
That the rollers and the coolant pump pulley turn freely (without play and without tight
spot).
That there are no signs of oil leaks (at the crankshaft and camshaft seals).
That there are no leaks of coolant fluid(at the coolant pump).
That the track of the engine speed sensor target (15)is not damaged or scratched.
Replace any components that are defective (if necessary).

Adjusting the timing belt tension.
Act on the tensioner roller (18)to align the marks «g»and «h», avoiding detensioning the
timing belt, using an allen spanner at «d».
Should this fail, repeat the operation to tension the timing belt.Hold the tensioner roller
(18).
Tighten the tensioner roller fixing nut to 3,7 ± 0,3 m.daN.
Check the position of the tensioner roller (the alignment of the marks «g»and «h»should
be correct).
Remove tools [2]and [3].
Rotate the crankshaft six times(clockwise).
IMPERATIVE:Never rotate the engine backwards.
WARNING:
Do not touch or damage the track of the target of the engine speed sensor (14).
Peg the crankshaft, using tool
[3].
Check the position of the tensioner roller (the alignment of the marks «g»and «h»should
be correct).
If this is not the case, repeat the operation to tension the timing belt.
Peg the camshaft pulley, using tool
[2].
IMPERATIVE: Should it be impossible to peg the camshaft, check that the offset bet
ween the camshaft hole and the pegging hole is not more than 1 mm. If the offset is
too great, repeat the operation.
Remove tools [2]and [3].
