1. Turn the crankshaft in its normal direction of rotation to align notch (1a) on the crankshaft pulley with ridge (1b) on the timing belt guard. Notch (1c) should now be aligned with rpm sensor (1d).

- 1032D12 timing system protective cover(s) - r + r1. Remove the tensioning device (1a) for the auxiliary shaft drive belt acting on the bolts (1b) to allow the subsequent positioning of the timing tool at '0'.

1. Using the dial gauge, recheck that the piston for cylinder no. 1 is at TDC then, using the bolt (1a) fixing the timing belt guard, fasten the fixed reference (1b) in the housing used for the actual bolt.

1. Fit the base of the tool (1a) on the auxiliary shaft belt drive pulley, securing it using the bolt shown in the diagram, then fit the graduated disc on the support base ensuring that the '0' on the disc is aligned with the fixed reference positioned previously.

1. Rotate the crankshaft through 10° in its normal direction of rotation as illustrated in the diagram using a special spanner on the nut (1a) fixing the auxiliary shaft drive pulley (1b); measure the piston axial movement on the dial gauge (e.g. 0.6 mm).

1. Rotate the crankshaft in the opposite direction to its normal direction of rotation through about 20 degrees from its previous position (the fixed reference, as illustrated, should be at about 10 degrees) until the same axial movement figure measured previously appears on the dial gauge (e.g. 0.6 mm).

1. Read the angle on the graduated disc corresponding to the previous axial movement (e.g. 8°). Take the arithmetical average of the angular value of the crankshaft set at the beginning of the procedure (10°) and the current value (8°), then release the graduated disc from its base, position it in relation to the fixed index, without rotating the crankshaft, at the value obtained from the arithmetical average (e.g. 9° = the average of 10° and 8°), then lock the graduated disc once again.

1. Rotate the crankshaft pulley in a clockwise direction until the '0' on the graduated disc coincides with the fixed reference.

1. Rotate the crankshaft through 10° clockwise and anti-clockwise, checking on the dial gauge that the reading for the clockwise rotation of the crankshaft is the same as that for the anti-clockwise rotation.

If the readings on the dial gauge after the above check are not the same, repeat the procedure described in the previous points.

- 5510C14 ignition coil/s - r+r1. Remove the rear covers (1a) for the camshafts acting on the fixing nuts and disconnecting the earth leads (1b) connected to them.

With the piston at TDC (fixed reference at zero on the graduated disc), proceed with timing the camshafts following the instructions given below. 1. Position the first of the camshaft timing adjustment tools.2. When fitting the tool, align the shaft seat (2a) with the key (2b) on the tool.3. Tighten the tool retaining nuts.

The tools are stamped with the letters 'A' (intake) and 'S' (exhaust) to facilitate correct positioning on the shafts. The tools are not interchangeable.

1. Loosen the nut fixing the automatic belt tensioner in order to release the belt tension.2. Remove the timing drive belt.

Refitting ( Removing

) 1. Using the tool (1a) for counter-torque, loosen the bolt (1b) fixing the pulley (1c) at the camshaft where the timing template was fitted previously.

Refit the timing belt and, with small rotations of the crankshaft, fit the second template without using force, the same way as the first template and lock it then remove the timing belt again and loosen the bolts fixing the second pulley still using the tool for counter-torque. With both templates fitted and the crankshaft at zero in relation to the fixed reference, refit the timing drive belt as follows.1. Fit it initially on the crankshaft gear.2. Fit the belt on the oil pump gear.3. Fit the belt on the fixed pulley.4. Fit the belt on the inlet camshaft pulley.5. Fit the belt on the exhaust camshaft pulley.6. Lastly, fit the belt on the automatic tensioning device.

1. Undo retaining bolts2. Position the toothed belt tensioning tool.3. Adjust the tool until the belt is as taut as possible, i.e. when the moving belt tensioner pointer is at the end of its travel.4. Tighten the tensioner retaining nut.

Rotate the crankshaft through two revolutions in its normal direction of rotation.1. Loosen the belt tensioner retaining nut and use tool (1a) to slightly release belt tension until moving reference (1b) is aligned with fixed reference (1c) on the tensioning device. 2.

Remove the tool and tighten the retaining bolt removed previously to the specified torque in order to fit the tensioning tool.

It is good practice to check timing again by refitting the tools to the camshafts and adjusting the engine until cylinder no. 1 is set to TDC, measured using the dial gauge and probe. If the engine timing is not correctly adjusted or the timing belt is found to be faulty, the removal-refitting and engine timing adjustment operation must be repeated.
