Attention: As part of the maintenance schedule, the toothed belt must be replaced every 4 years. If the toothed belt is removed, it must be replaced regardless of its service life.
Withdrawal
Remove the engine compartment hood.
Remove the ignition distributor cover. To do this, use a screwdriver to lift the clips at the top and bottom.
Raise the cable duct with a screwdriver.
Unscrew the cover of the distributor of ignition 1 and remove it together with the ignition wires. This requires an 8 mm socket wrench, e.g. HAZET850-8 with 865.
Unscrew the runner of the ignition distributor 2 with a 3 mm socket wrench and remove it together with the ring 3.
Unscrew top cover 4 for toothed belt.
Unfasten the rubber cover.
Raise the cable duct under the distributor and move it to the side.
Set cylinder 1 to top dead center. To do this, put the transmission into neutral and apply the handbrake. Turn the crankshaft behind the belt pulley in the direction of engine rotation.
(See fig. W-1086) Rotate the crankshaft until notch 1 on the camshaft sprocket coincides with mark 2 on the cylinder head. At the same time, the top dead center mark on the flywheel must match the reference mark. To crank the engine, you can also engage 5th gear and move the vehicle with the handbrake released on level ground.
Unscrew vibration damper 1 from the crankshaft. At the same time, engage 1st gear, apply the handbrake, thus holding the belt pulley.
Disconnect the reference point sensor connector under the intake pipe.
If equipped, disconnect the cylinder identifier connector.
Disconnect the oil pressure switch connector.
Loosen the alternator tensioner nut on the engine block.
Remove upper toothed belt cover.
Fully unscrew the tension bar and remove the lower casing.
Loosen bolts E and F and press tensioning roller R with a screwdriver.
Tighten bolt E.
Remove toothed belt.
Caution: When the toothed belt is removed, if possible, do not turn the engine, otherwise the pistons and valves can be severely damaged.
Installation
Attention: When applying a toothed belt, the position of neither the camshaft nor the intermediate shaft must be lost. Otherwise severe engine damage may occur or the engine will not develop full power. After tensioning the toothed belt, it is recommended to check the installation of the crankshaft and camshaft again.
Pattern W - 1041
1 crankshaft
2 Intermediate shaft
3 Camshaft
4 Tension roller
Fit new toothed belt. When doing this, start with the crankshaft sprocket 1 and fit the toothed belt Z in the order shown in the figure.
