Preventions
1. Do not overwind and do not bend a gear belt. Exclude hit on a gear belt of oil, cooling liquid or fuel.
If teeths of a gear belt vykroshitsya, perhaps, jammed the ignition distributor, the water pump, the oil pump or the camshaft.
2. The gear belt can become torn on the working engine as a result of blow of pistons about valves therefore valves can be bent. Check gaps of valves. On the bent valves gaps will be much more demanded.
If the external surface of a gear belt is considerably worn-out or stratified, check a condition of a racetrack of single pulleys.
If only one party of a belt is worn-out or damaged, check a guide of a gear belt and alignment of pulleys of a gear belt.
   With any defects on a gear belt it needs to be replaced.

Installation and adjustment of a tension
Establish a gear belt on a pulley of a bent shaft.
Establish a quencher of fluctuations.
Screw and tighten by hand four bolts of fastening of a quencher of 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 bent shaft. For an exception of a provorachivaniye of a pulley record it special adaptation.
Make sure 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.
