[2] Camshaft setting rod (Exhaust) (-).0132 AJ1 .

[3] Camshaft oil seal fitting drift (-).0132 AG .

[4] flywheel setting rod (-).0132 QY .

2 - REMOVAL

Remove the style cover (1) .

Remove :

• the ancillary drive belt
• the crankshaft pulley

Support the power train assembly by sliding a stand under the engine .

Remove :

• the complete left engine store (2)
• the top timing cover (3)
• the bottom timing cover (3)
• the style cover (4)

Peg the flywheel using the rod [4] .

Remove the tool [4] .

Turn the engine 1/4 of a revolution in reverse .

Progressively slacken in a spiral sequence the bolts of each cylinder head cover (5), starting from the outside .

Remove the cylinder head covers .

Slacken the camshaft hub securing bolts, immobilizing the camshafts by means of a spanner at (A) .

Remove :

• the timing belt (6)
• the hub-pulley assembly (7)
• the timing cover (8)
• the camshaft oil seals

WARNING : slacken the camshaft bearing cap cover (9) securing bolts, progressively and in a spiral sequence starting from the outside, so as to separate the mating surfaces by a few millimetres .

Disengage the camshaft from its bearings by tapping lightly with a mallet from the pulley side .

Remove :

• the main bearing cap casting (9)
• the camshaft (10)

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 (MOLYDAL GB SP 370G)
• refit the tappets in their original positions
• check that the tappets rotate freely in the cylinder head

Lubricate the cams and the bearings (MOLYDAL GB SP 370G) .

Refit the camshafts in the cylinder head, positioning the notches (B) :

• 7h : inlet side
• 8h : exhaust side

Carefully clean the mating surfaces of the cylinder head and camshaft bearing cap cover .

Check that the pins (11) are present .

Deposit a line of sealing compound AUTOJOINT OR at (C) around the edge of the mating surfaces .

Refit the camshaft bearing cap covers .

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

• pre-tighten : 0.2 da.Nm
• tightening torque: 0.8 da.Nm

Refit the camshaft seals (12) using the tool [3] .

Refit the timing cover (7), engaging the notch (D) of the timing cover correctly on the rib (E) of the seal carrier plate .

Refit the hub-pulley assemblies (8) .

Tighten the camshaft hub securing bolts to 8 da.Nm immobilizing the camshaft by means of a spanner at (A) .

WARNING : ensure that the camshaft pulley turns freely on its hub .

Peg :

• the camshaft hubs, using the rods [1] - [2]
• the engine flywheel using tool [4]

Fit :

• the timing belt
• the timing cover

Refit the cylinder head covers (5) after cleaning the seals and joint faces .

NOTE : the cylinder head covers have composite gaskets which can be used several times ; if the gasket is damaged, it can be partially repaired with SILICONE CATEGORIE 2 jointing paste .

Continue the fitting operations in the reverse order to removal .
