Removal
Loosen the generator mounting bolts and remove the generator drive belt.
Remove the crankshaft pulley.
Remove the timing belt protective covers.
Disconnect the high voltage wire harness.
Remove the spark plugs from the cylinder head sockets.
Turn the crankshaft to the TDC position of the compression stroke of the piston of the 1st cylinder, aligning the mark on the flywheel with the installation protrusion on the clutch housing and placing the mark on the camshaft pulley at the level of the cylinder head gasket (see photo).
Loosen the tension roller axle mounting nut.
Remove the camshaft timing belt.
Installation
Note: Do not turn the camshaft when any of the pistons is at TDC.
Set the camshaft to the TDC position of the ignition stroke of the piston of the 1st cylinder, placing a mark on the camshaft pulley at the level of the cylinder head gasket.
Turn the intermediate shaft toothed pulley so as to align the mark on it with the TDC mark of the 1st cylinder piston on the crankshaft pulley.
Set the crankshaft to the position corresponding to the TDC of the compression stroke of the piston of the 1st cylinder according to the marks on the flywheel and on the clutch housing.
Place the timing belt on the pulleys.
Adjust the tension of the toothed belt by turning the tension roller on the axis in the direction opposite to the direction of rotation of the toothed belt.
Turn the crankshaft two revolutions and check that the timing belt tension is adjusted correctly.
Remove the crankshaft pulley and install the timing belt protective covers.
Install the crankshaft pulley.
Install the generator drive belt and adjust its tension.
Tighten the generator mounting bolts.
Screw in the spark plugs and connect the high voltage wires.
Check and, if necessary, adjust the ignition timing.
