2 - REMOVAL

EW10J4 ENGINE EMISSION CONTROL CEE 95

remove the timing belt .

Remove the style cover .

Remove :

• the camshaft setting rods [1]
• the camshaft pulleys (1) and (2)
• the compact coil unit (3)
• the sensor (4)
• the cylinder head covers (5), (6) (slacken the bolts progressively in a spiral sequence, starting from the outside)

Position the 24 mm open-ended spanner on the flat surface (7) of the camshaft .

Slacken the bolt (8) .

Repeat the operation for the second camshaft .

Remove the hubs (9) .

Remove the cover (10) .

Slacken the camshaft bearing cap cover securing bolts, progressively and in a spiral sequence starting from the outside, so as to separate the mating surfaces by a few millimetres .

Remove the camshaft bearing housings .

Remove the camshafts :

• tilt each camshaft by pressing on the end (clutch side) to release the centralising bearing (timing side)

If the tappets are removed :

• mark the positions of the tappets before removal
• use a valve grinding type suction cup tool

Remove oil from the threads receiving the camshaft bearing housing securing bolts .

3 - REFITTING

Refitting the tappets :

• lubricate the tappet bodies
• refit the tappets in their original positions
• check that the tappets rotate freely in the cylinder head

Oil the camshaft bearings .

EW10J4 ENGINE EMISSION CONTROL CEE 95

Check that the pins (11) are present .

Position the camshaft fitted with the sensor ring (4) on the exhaust side .

Position the second camshaft .

Apply a bead of SILICONE CATEGORIE 2 jointing paste at (A) round the perimeter of the joint faces and the tappings for the securing bolts .

EW10J4 ENGINE EMISSION CONTROL CEE 95

Replace the bearing housing with the sensor hole (4) on the exhaust side .

Refit the second bearing housing .

Finger tighten then progressively tighten the securing bolts in the order shown 1 to 12 .

Pre-tightening 0,5 da.Nm .

Tightening torque of bolts : 1 da.Nm .

Replace the timing gear cover .

Before fitting the camshaft seal, ensure that the bottom of the seat is free of sealing compound .

Fit new seals using the tool [2] .

4 - CAMSHAFT HUB IDENTIFICATION

EW10J4 ENGINE EMISSION CONTROL CEE 95

Identification of the camshaft hubs is possible because of a stamp (B) consisting of one digit .

ALL MODELS

5 - REFITTING (CONTINUED)

EW10J4 ENGINE EMISSION CONTROL CEE 95

Tighten the bolts securing the camshaft hubs to 7.5 daN.m by immobilising the camshaft by means of an open-ended spanner .

Refit the cylinder head covers fitted with new gaskets in the order indicated .

Stage 1 :

• proceed bolt by bolt in the order shown
• tightening torque of bolts : 0,5 da.Nm

Stage 2 :

• proceed bolt by bolt in the order shown
• tightening torque of bolts : 1,1 da.Nm

refit the timing belt .

Continue the fitting operations in the reverse order to removal .

Initialise the various ECUs .
