[5] hub immobilising tool (-).0606-A1/(-).0606-A2 .

[6] Belt retaining clip (-).0189-K .

2 - REMOVAL

Disconnect the battery .

Remove :

• the front right-hand wheel
• the mud shield (front RH)
• the ancillary drive belt

EW12J4 ENGINE

Remove :

• the style cover (1)

Remove the torque reaction link (2) .

NOTE : retrieve the yoke (3) .

Remove :

• the bolts (4) + the ancillary drive pulley
• the timing cover (5)
• the timing cover (6)

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

IMPERATIVE : do not slacken the securing bolts (7) .

Peg :

• the exhaust camshaft,using the tool [2]
• the inlet camshaft,using the tool [3]
• the crankshaft,using the tool [1]

Slacken the bolt (8) (Fully) .

Remove the roller bracket (9) from the rib (B) of the cylinder block (to allow it greater movement) .

Remove the timing belt .

3 - REFITTING

Always renew : The timing belt .

EW12J4 ENGINE

IMPERATIVE : check that the rollers (10), (11) as well as the coolant pump (12) turn freely (no play or hard spots); also check that these rollers are not noisy and/or do not show traces of grease .

In the event of replacement, Tightening torque(s) :

• roller (11) to 3.5 m. daN

Engage belt on crankshaft pinion (13) respecting its fitting direction .

Immobilise the belt using the tool [6] .

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

• roller tensioner (11)
• the pinion (14)
• the pinion (15)
• the coolant pump (12)
• the tensioner roller (10)

Correct the alignment of the belt by placing the centre line of the belt as near to vertical as possible but not flush with flanges .

4 - FITTING AND TENSIONING THE TIMING BELT

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

EW12J4 ENGINE

Position the roller bracket (9) back on rib (B) of the cylinder block .

Remove the tool [6] .

(C) : Maximum position .

(D) : Nominal tensioning position .

Using the hexagonal socket (E), turn the roller in the direction of the arrow until the pointer (16) 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 (E) until cursor just makes contact with pin [4] .

IMPERATIVE : never turn the roller (10) by one full turn .

NOTE : this operation allows the pointer (16) to be located in the nominal position (D) .

Tighten screw (8), supporting roller with torx recess (E) : Tightening torque : 2 da.Nm .

Remove setting rods [1], [2], [3] and [4] .

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

IMPERATIVE : never turn the crankshaft in the reverse direction .

IMPERATIVE : no pressure or outside force must be applied to the belt .

5 - CHECK

5 - 1 - TIMING BELT TENSION

EW12J4 ENGINE

Check position of tensioner index (16) .

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

5 - 2 - POSITION OF THE CRANKSHAFT

EW12J4 ENGINE

.

ALL MODELS

Insert pin to locate inlet camshaft pulley, Using the tool [3] .

Peg the crankshaft, Using the tool [1] .

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

EW12J4 ENGINE

IMPERATIVE : if it is not possible to fit tool [1], reposition flange (18) .

5 - 3 - REPOSITIONING OF FLANGE

EW12J4 ENGINE

Immobilise crankshaft, Using the tool [5] .

Loosen screw (17) to release pinion (13) from crankshaft .

Position flange (18) at timing point, Using the tool [5] .

Fit the tool [1] .

Tighten screw (8) to 4 +/- 0.4 dan.m, then proceed with angular tightening of 53 +/- 4, Using a FACOM D360 type tool .

Remove the tools [1], [3], [5] .

6 - REFITTING (CONTINUED)

EW12J4 ENGINE

Fit :

• the timing cover (6)
• the ancillary drive pulley
• the bolts (4) to 2.1 da.Nm
• the timing cover (5)

Fit :

• the torque reaction link (2)
• the yoke (3)

Tighten :

• the bolt (19) to 4.5 da.Nm
• the bolt (20) to 4.5 da.Nm

Continue the fitting operations in the reverse order to removal .

replace the style cover (1) .

fit the ancillary drive belt .
