Open the hood, remove the spare wheel and disconnect the wire from the negative terminal of the battery. Remove the windshield washer reservoir and the ignition coil with high-voltage wires. Remove the front toothed belt cover.
Loosen the alternator drive belt and remove it from the pulleys. Remove the pulley (with key) generator drive from the crankshaft and tighten the pulley mounting bolt back into place.
Set the gearbox lever to neutral and turn the crankshaft clockwise to a position where the mark on the flywheel (see figure 67), visible in the clutch housing hatch, was opposite the middle division of the scale. In this case, the mark on the camshaft pulley should be opposite the installation mark on the rear protective cover of the toothed belt.
Loosen the tension roller axle mounting nut and turn it to a position where the belt is as loose as possible. Remove the belt from the pulleys.
Put the new belt on the camshaft pulley and, while pulling both branches of the belt, put the left branch behind the tension roller, and then wrap it around the coolant pump pulley. Put the lower part of the belt on the crankshaft pulley and slightly tighten it with the tension roller, turning the roller axis counterclockwise. When installing the belt, avoid sharp bends with a radius of less than 20 mm, so as not to damage the belt fiberglass.
Turn the crankshaft two revolutions clockwise and check whether the timing marks on the pulley and the rear protective cover of the toothed belt match, and whether the mark on the flywheel is opposite the middle division of the scale (see figure 67).
If the marks do not match, then repeat the belt installation operation, adjusting the position of the camshaft pulley. If the marks match, then engage the 4th gear in the gearbox, unscrew the bolt from the crankshaft, install the key and the generator drive pulley and secure it with a bolt and washer, finally tightening it to a torque of 102.9 N·m (10.5 kgf·m).
Adjust the belt tension and install the front toothed belt cover. Put on the generator drive belt and adjust its tension (see section. "Engine adjustment").
Install the ignition coil and high voltage wires.
Connect the wires to the negative terminal of the battery, check and adjust the ignition timing (see section. "Engine adjustment").
The windshield washer reservoir and spare wheel are installed.
