Remove гаситель fluctuations, thus the pulley of a gear belt of a cranked shaft should remain on a place.
Remove a gear belt.
Do not turn a cranked shaft of the engine at the removed gear belt as pistons can hit about valves.
Preventions
1. Do not overwind and do not bend a gear belt. Exclude hit on a gear belt of the oil, cooling liquid or fuel.
If teeths of a gear belt выкрошились, probably, has jammed the distributor of ignition, the water pump, the oil pump or a camshaft.
2. The gear belt can be broken off on the working engine as a result of blow of pistons about valves therefore valves can be bent. Check up backlashes of valves. On погнутых valves backlashes will be much more demanded.
If the external surface of a gear belt is considerably worn out or stratified, check up a condition of a racetrack of single pulleys.
If one party of a belt is worn out or damaged only, check up directing a gear belt and alignment of pulleys of a gear belt.
In the presence of any defects on a gear belt it is necessary to replace it.
Installation and tension adjustment
Establish a gear belt on a pulley of a cranked shaft.
Screw and tighten by hand four bolts of fastening гасителя fluctuations.
Grease with a thin layer of engine oil a carving and a basic surface of a head of a bolt and screw in a bolt of fastening of a pulley of a cranked shaft. For an exception проворачивания a pulley fix its special adaptation.
Be convinced that pulleys of a gear belt of camshafts are freely turned on cones, i.e. bolts of fastening of pulleys are turned out on one turn.
Establish a gear belt on all pulleys, including a pulley of the water pump.
Tighten a nut of fastening of a tension roller of a gear belt so that the clown of a roller still it was possible to turn.
Tighten four bolts of fastening гасителя fluctuations.
