Check of a condition of driving ridge belts

1 Tension of a ridge belt is made automatically. It is necessary to check periodically a belt condition, and at detection of defects, to replace a belt.
2 Driving belts sometimes called by V-shaped belts of section or simply ventilyatorny belts, are in a forward part of the engine and play important role in operation of the car and its separate components. Because of features of a material and operating conditions driving belts fail after a while, and consequently their condition it is necessary to check and regulate periodically effort of a tension in order to avoid serious damages of the engine.
3 Quantity of the belts used on the concrete car, depends on the units established on it and systems. Driving belts are applied to actuating of the generator, the steering pump, the water pump and the compressor of central air of air. Depending on an arrangement of pulleys one belt can put in action at once some components.
4 Switch off the engine, open a cowl and find various driving belts in a forward part of the engine. Fingers (and using a small lamp if it is necessary) walk on all length of each belt, feeling them on existence of cracks and stratifications. Also check, whether is not present on belts of attritions and zapolirovanny sites to shine. Each belt should be examined from both parties that means need of its perekruchivaniye for check of a condition of seamy side.


5 Tension of a belt is checked by strong pressing on it by a thumb and definitions of degree of its deflection. Size of a deflection measure by a ruler. If the distance between centers pulleys makes from 180 to 280 mm, the deflection size when pressing by a thumb should equal 6 mm. If the distance between centers pulleys is in limits between 300 and 400 mm, the deflection should be 13 mm.
