1. Remove the inlet manifold complete with injectors and butterfly casing.

1. Remove the upper shield (1a) and the lower shield (1b) for the timing belt.

1. Undo the bolts indicated and remove the auxiliary shaft drive pulley on the crankshaft.

Remove the protective cover for the camshaft rear gears.1. Undo the camshaft housing side plugs.2. Position the tools (1a) in the housings for the plugs undone previously, then rotate the camshafts until the splining on each camshaft coincides with the pin (2b) for the tools. The camshafts will be timed in this way.

1. Check that the centering lug (1a) on the crankshaft gear (1b) is positioned opposite the housing for the rpm and TDC sensor (1c). The pistons will be approximately aligned with one another in this position.

1. Loosen the nut fixing the automatic belt tensioner.2. Remove the timing drive belt.

Refitting ( Removing

) Remove the spark plugs for cylinders 1 and 2.1. Position the tools (1a) in the housings for the spark plug for cylinders 1 and 2, tightening the components (1b) to a torque of 0.5 daNm.2. Rotate the crankshaft in its normal direction of rotation, using small movements, until the surface (2a) on the moving part of the tool is aligned with the plane (2b) on the fixed part in the spark plug housing. When both tools positioned in the spark plug housing are in this condition the pistons will be aligned, i.e. halfway through their stroke and the piston for cylinder 1 will be descending, i.e. in the inlet stroke.

The pistons were already approximately aligned previously.

Rotate the crankshaft gradually to prevent the pins for the tools being expelled by the piston compression.

The camshafts were timed previously through the fitting of the tools (3b).

1. Proceed with fitting the timing drive belt, fitting it initially on the crankshaft gear (1a), the water pump pulley (1b), the camshaft drive pulley (1c) and, lastly, on the belt tensioner pulley (1d).

Make sure that this operation is carried out with the camshaft pulley (1c) slack.

1. Using suitable pliers, rotate the automatic tensioner placing it in the maximum tension position, i.e. with the moving reference (1a) positioned as illustrated in the diagram then lock the nut (1d) fixing the tensioner to the support.

1. Using the tool (1a) tighten the bolt (1b) fixing the camshaft pulley to the recommended torque.

Remove the tools positioned previously for timing and locking the camshafts and rotate the crankshaft through two revolutions in its direction of rotation to let the timing drive belt bed in.

1. Loosen the nut fixing the tensioner and ensure that the moving reference (1a) coincides with the fixed reference (1b) retaining the tensioner using the special pliers so as not to release the tension suddenly.2. Once the two references are aligned, tighten the nut (2a) fixing the tensioner to the recommended torque.Rotate the crankshaft through a further two revolutions in its direction of rotation, then repositino the tools used for timing the engine and check that the timing is correct.Refit the side plugs in the camshaft housing.
