Check of a condition of driving ridge belts

1 The tension of a ridge belt is made automatically. It is necessary to check periodically a condition of a belt, and at detection of defects, to replace a belt.
2 Driving belts sometimes called by belts of V-shaped section or simply ventilatory belts are in forward part of the engine and play an important role in operation of the car and its separate components. Because of features of material and operating conditions driving belts fail after a while and therefore their state it is necessary to check and regulate periodically effort of a tension in order to avoid serious damages of the engine.
3 The quantity of the belts used on the concrete car depends from installed on it units and systems. Driving belts are applied to actuating of the generator, the steering pump, the water pump and the compressor of the air conditioning system. 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 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 sites, zapolirovanny to gloss. Each belt has to be examined from both parties that means need of its twisting for check of a condition of seamy side.


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