Loosen the nut retaining the timing belt moving tensioner.2. Release and remove the toothed timing drive belt.

Refitting ( Removing ) 1. Remove plug (1a) and fit the camshaft timing tool (1b) to the cylinder head extension from the exhaust side.

Check the tool is correctly fitted in its seat on the exhaust side camshaft.

1b	Templates	1.870.896.900	Engine tuning

2. Loosen the bolt securing the exhaust side timing belt toothed drive pulley.

1. Undo the bolt fixing the crankcase front cover shown in the diagram.- Fit the timing drive belt on the drive gear, checking that the belt teeth are correctly inserted in the gear grooves.2. Fit the tool (2a) and fasten it using the calibrated screw (2b).

The crankshaft must be rotated, using small movements, to allow the locating dowel to be fitted on the timing drive pulley.

- Rotate the crankshaft through two revolutions.- Re-check the timing by refitting the timing adjustment tools.

Fit only the exhaust camshaft side template because the intake side template seat is not accessible.

- Check the alignment of the tensioning reference marks on the mobile timing tensioner.- Tighten the bolt fixing the crankcase front cover removed previously.- Tighten the plug on the cylinder head extension for fitting the exhaust side timing adjustment tool.    See in Op. 1032D12 Timing system protective COVER(S) - R.R.    See in Op. 1092A10 Crankshaft PULLEY - R.R.    See in Op. 1092G21 Engine components single belt FIXED TENSIONER - R.R. with belt removed    See in Op. 1092G10 Engine components single drive BELT - R.R.    See in Op. 1048A56 UPPER RESONATOR - R.R.    See in Op. 1048B44 RIGID air supply PIPE from heat exchanger to intake manifold - R.R.    See in Op. 7040D50 ENGINE COMPARTMENT UPPER SOUND INSULATION SHIELD - R.R.    See in Op. 1016A10 SOUND-PROOFING COVER - R.R.    See in Op. 7055B64 Engine compartment DUST SEAL in front wheel arch (one), left or right - R.R.    See in Op. 7055B42 FRONT WHEEL ARCH LINER (one), left or right - R.R.    See in Op. 7055B54 PROTECTION/GUARD under engine - R.R.    See in Op. 4450B04 Right FRONT WHEEL (one) - R.R.- Top up the coolant as described in the operation:    See in Op. 0010T21 ENGINE COOLANT - Check density and top up if necessary- Connect the negative battery terminal.- Remove the vehicle from the lift.
