Instructions for correct checking of toothed timing belt condition:

Check that the timing belt does not show signs of loose threads or cracks.Check for 'black dust' along the entire length of the belt, on the toothed wheels, the shields, etc.Visually inspect the belt teeth for check for any wear of the protective outer fabric.If one or more of the above conditions indicating excess wear is found, replace the timing drive belt. .The entire length of the belt should be inspected.

Refitting ( Removing

) 1. Fit the tool (1a), complete with dial gauge (1b), in the housing of the spark plug for cylinder no. 1.

	Name	Country
1a	Fitting tool	1.821.225.000

Rotate the crankshaft, using small movements (in both directions), until the piston for cylinder no. 1 is at T.D.C. at the power stroke.

Make sure that the last crankshaft rotation is in the direction of operation.

2. Carry out a preliminary check on the camshaft timing: fit a spanner in the special opening (2a) in the centre of the camshafts and rotate them until the reference marks (2b) on the actual shafts coincide with the cylinder head upper surface.

The reference marks should be facing the centre of each cylinder head.

Remove the camshaft caps 4 and 7 from the left cylinder head.1. Position the timing templates in place of the camshaft caps removed.

1b	Counter-torque	1.822.146.000

Fit the timing drive belt starting from the drive pulley and continuing in an anti-clockwise direction, making sure that the drive sections are firmly taut.1. Fit the tool (1a) and secure it with the bolt (1b) to the alternator bracket and with the bolt (1c) to the water pump.

The tool tooth should press on the moving part of the timing belt tensioner.

2. Act on the nut (2a) for the belt tensioner tool until the moving reference on the belt tensioner (2b) is under the fixed reference.

1. Tighten the bolts (1a) fixing the driven pullies to the recommended toruqe using the tools (1b) and (1c).

Rotate the crankshaft through two revolutions in its direction of rotation to allow the timing belt to bed in.1. Check that the moving reference on the timing belt moving tensioner lines up with the fixed reference.2. If the references do not line up, slightly discharge the tensioner acting on the tensioning tool nut and make sure that the references are aligned. 3. Tighten the bolts for the moving tensioner to the recommended torque.
