) Position the cylinder head on a suitable workbench.1. Undo connectors (1a) and remove the high pressure fuel pipe (1b).

The high pressure fuel pipe must be replaced whenever at each reassembly.

1. Undo the bolts (1a) and remove the high-pressure fuel pump (1b) complete with O-ring (1c).

1. Loosen the bolt (1a) for the exhaust side timing driven pulley using tool (1b) for counter-torque.

2. Remove the exhaust side driven toothed pulley.

Check that the camshaft end float is within the recommended values using a dial gauge on a magnetic base.

	Measurement		Value
-	Camshaft end float (mm)		0.10 ÷ 0.23

If the camshaft endfloat is not within the recommended values, when reassembling the cylinder head, replace the worn components.

1. Undo the bolts (1a) and remove the camshaft caps (1b).

The front cap has silicone sealant, so a plastic hammer should be used for its removal.

2. Remove the upper bearing shell for the front camshaft support, inlet side.3. Remove the camshafts.4. Remove the front camshaft oil seals.5. Remove the lower bearing shell for the front camshaft support, inlet side.

Refitting ( Removing

) Clean any residues of sealant from the matching surfaces of the cylinder head and front journal cap.Place the inlet side camshaft front support lower bearing shell back in its housing.Place the camshafts back in their housings.Place the inlet side camshaft front support upper bearing shell back in its housing.1. Place the camshft caps (1a) back in their housings and secure them tightening the bolts (1b) to the recommended torque.

Apply silicone sealant between the front cap and the cylinder head.
