Setting the timing (continued).
Turn the tensioner roller to the right to bring the index «c»to position «d», using a
hexagonal spanner.
Tighten the screw
(9)of the tensioner roller, tighten to 3 ± 0,3 m.daN.
Remove the tools [4]and [5].
Rotate the engine
ten times(check that the timing pinion is correctly up against the
crankshaft).
Check:
The pegging of the camshaft.
The crankshaft pinion.
The fuel high pressure pump pinion
(15).
The correct positioning of the index of the dynamic tensioner.
If these are not correct, repeat the operation to position the timing belt.Refit:
The engine speed sensor
(6).
The belt retaining stop (5), tighten to 0,7 m.daN.

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 «f»and «g»should be correct).
If this is not the case, repeat the operation to tension the belt.Peg the camshaft pulley, using tool
[2].
IMPERATIVE: Should it be impossible to peg the camshaft, check that the offset between the
camshaft hole and the pegging hole is not more than 1 mm. If the offset is too great, repeat theoperation.
Remove the pegs [2]and [3].
Refit tool

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].
