1 - SPECIAL TOOLS

[1] Crankshaft setting rod (-).0194-A .

[2] camshaft gear setting rod (-).0194-B .

[3] Timing tensioner roller pin (-).0194-F1 .

[4] Prevention of engine flywheel (-).0194-C rotation .

2 - REMOVAL

Remove :

• the front right-hand wheel
• the front right mud shield
• THE ANCILLARY DRIVE BELT

Place the tool [3] in the hole located in the crankshaft main bearing cap casting (A) .

Remove the ancillary drive pulley .

Move the electrical harness aside from the upper timing cover .

Remove the lower and upper timing covers .

Remove the engine speed sensor (1) .

IMPERATIVE : the magnetic track (B) must not show any signs of damage and magnetic sources must be kept away from it ; otherwise, the crankshaft pinion will have to be replaced .

Remove the angle bracket which is to prevent shifting of position .

Refit the screw of the pulley driving the accessories .

Remove the tool [3] .

Turn the crankshaft clockwise using the ancillary drive bolt .

Peg the camshaft pulley with tool [2] .

Pin the crankshaft in the oil pump using the tool [1] .

Place a jack with a wooden shim under the oil sump to support the engine on removal of the right-hand engine mounting .

Remove the right-hand engine mounting (2) and its intermediate support (3) .

Slacken the tensioner roller mounting bolts (4) retaining slackness by using a hexagonal wrench .

Remove the timing belt .

3 - REFITTING

Check that the rollers as well as the coolant pump turn freely (no play or hard spots) .

Also check that these rollers are not noisy and/or do not show traces of grease .

Tighten :

• the bolt securing the roller ; 4.5 da.Nm
• the tensioner roller mounting bolt ; 1 da.Nm

Check the sealing of the sealing rings at the oil pump and at the crankshaft .

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

• timing gear
• roller tensioner
• camshaft pulley (ensuring that the belt is placed correctly against the roller)
• high pressure pump
• coolant pump
• roller tensioner

Refit the anti-shift angle bracket and tighten it to 0.7 dan.m .

Slacken the tensioner roller (4) bolt .

Using a hexagonal wrench move the tensioner roller index C to the middle of checking zone D turning the tensioner clockwise .

Tighten the bolt (4) to 3 da.Nm .

Remove the tools [1] - [2] .

Carry out 10 engine revolutions ensuring that the timing pinion is placed correctly on the crankshaft .

Put the tools in place [1] - [2] .

Check that the dynamic tensioner (C) index is positioned correctly ; If this is not the case, restart the belt fitting operation .

Remove the tools [1] - [2] .

Refit the engine speed sensor on the oil pump .

Tightening torque 0.7 da.Nm .

Refit the intermediate engine mounting (5) .

Tighten the bolts (6) to 5.5 daN.m .

Fit :

• the right-hand engine mounting (7) ; tighten the bolts (8) to 6 daN.m
• the lower timing cover
• the tool [3] on the engine flywheel

Slacken the ancillary drive pulley mounting bolt .

Tightening torque 3 da.Nm + 180° .

Remove the tool [3] .

The ancillary drive belt .

Fit :

• the front right mud shield
• the front right-hand wheel
• the top timing cover
• the electrical harness on the timing cover
