Turn out a bolt of fastening of a pulley of a cranked shaft.
Remove vibration damper, while the crankshaft timing belt pulley remains in place.
Remove the toothed belt.
Do not rotate the engine crankshaft with the toothed belt removed, as the pistons may hit the valves.
Warnings: 1. Do not twist or bend the toothed belt. Do not expose the toothed belt to oil, coolant or fuel.
If the toothed belt teeth are chipped, the ignition distributor, water pump, oil pump, or camshaft may be stuck.
2. The timing belt may break while the engine is running as a result of pistons hitting the valves, causing the valves to bend. Check valve clearances. On bent valves, the gaps will be much larger than required.
If the outer surface of the toothed belt is significantly worn or delaminated, check the condition of the idler pulley treadmill.
If only one side of the belt is worn or damaged, check the toothed belt guide and the alignment of the toothed belt pulleys.
If there are any defects on the toothed belt, it must be replaced.
Tension setting and adjustment
Install the toothed belt onto the crankshaft pulley.
Install vibration damper.
Screw in and hand-tighten the four vibration damper mounting bolts.
Lubricate the threads and bearing surface of the bolt head with a thin layer of engine oil, and screw in the crankshaft pulley bolt. To prevent the pulley from turning, fix it with a special tool.
Make sure that the camshaft timing belt pulleys turn freely on the cones, i.e. pulley bolts are backed out one turn.
Install the toothed belt on all pulleys, including the water pump pulley.
Tighten the toothed belt tensioning roller nut so that the roller eccentric can still be turned.
Tighten the four vibration damper mounting bolts.
