[6] Engine lifting tool .

[7] Engine hook (-).0102-ZV .

2 - REMOVAL

Remove :


Remove :


Using the tools [6] and [7], secure on the sling hook .


Remove :

Move aside the power steering pipes .

Remove the lower timing cover (6) taking care not to damage it .

WARNING : do not slacken the securing bolts (A) .


Peg :

Slacken the bolt (7) (Fully) .

Remove the roller bracket (8) from the rib (B) of the cylinder block (to allow it greater movement) .

Remove the timing belt .

3 - REFITTING

Always replace the timing belt .


IMPERATIVE : check that the rollers (9) - (10) as well as the coolant pump (11) turn freely (no play or hard spots) ; also check that these rollers are not noisy and/or do not show traces of grease .

If the idler roller (10) is replaced, tighten to 3.5 dan.m .

Fit the belt on the crankshaft gear following the direction of fitting (12) .

Immobilise the belt using the tool [3] .

Fit the timing belt, fully taut, in the following order :

4 - FITTING AND TENSIONING THE TIMING BELT

IMPERATIVE : operation(s) to be carried out with the engine cold .


Position the roller bracket (8) back on rib (B) of the cylinder block .

Remove the tool [3] .


C : Maximum position .

D : Nominal tensioning position .

Using the hexagonal socket (E), turn the roller in the direction of the arrow until the pointer (15) is in position (C) to tension the belt to the maximum .

Fit the tool [4] .

Turn the roller in the direction opposite to that shown on the roller arrow by means of the torx recess until cursor just makes contact with pin .

IMPERATIVE : never turn the roller (9) by one full turn .

NOTE : this operation allows the pointer (15) to be located in the nominal position (D) .

Tighten screw (7), supporting roller with torx recess (E) : Tightening torque 2 da.Nm .

Remove setting rods [1] - [2] and [4] .

Turn the crankshaft 10 turn(s) in the direction of running .

IMPERATIVE : never turn the crankshaft in the reverse direction ; no pressure or outside force must be applied to the belt .

5 - CHECK

5 - 1 - TIMING BELT TENSION


Check position of tensioner index (15) .

If tensioner index (D) is not in its adjustment position : Restart tensioning operations for fitting the timing belt .

5 - 2 - POSITION OF THE CRANKSHAFT

Insert pin to locate inlet camshaft pulley (Using the tool [2]) .

Peg the crankshaft (Using the tool [1]) .

If it is possible to fit tool [1], continue replacement operations .

If it is not possible to fit tool [1], reposition flange (16) .

5 - 3 - REPOSITIONING OF FLANGE


Immobilise crankshaft (Using the tool [5]) .

Loosen screw (17) to release pinion (12) from crankshaft .

Position flange (16) at timing point (Using the tool [5]) .

Fit the tool [1] .

Tighten screw (17) to 4 ± 0.4 dan.m, then proceed with angular tightening of 53 ± 4 (Using a FACOM D.360 type tool) .

Remove the tools [1] - [2] - [5] .

6 - REFITTING (CONTINUED)


Fit :

Tightening of the 7 bolts of the bracket to 6 dan.m .

Remove the tools [6] - [7] .

fit the ancillary drive belt .

Continue the fitting operations in the reverse order to removal .

Tighten the wheels to 9 daN.m .
