2.29. Check of a condition of driving ridge belts

PERFORMANCE ORDER
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. The driving belts sometimes called by belts of V-shaped section or just ventilatory belts are in a 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. 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 several components at once.
4. Switch off the engine, establish RKPP in neutral situation. Lift and install the car on supports.
5. Remove the lower cover of a motive compartment, address the subsection Removal and installation of the lower cover of a motive compartment.
6. Mark chalk a belt-1-on well foreground.
7. From the lower party of the engine a head turn the engine for a pulley of a bent shaft in the direction of rotation, i.e. to the right side so that cretaceous marking was visible. At the same time the site behind the site see a belt.
Wear of edges of edges of a ridge belt
Cross cracks of D from a reverse side of a belt and peeling of edges E ridge belts
Razlokhmachivaniye of side edges of F, crack of N and peeling of side edges of G
Separation of edges of J, K crack
8. Fingers (and using a small lamp if it is necessary) walk on all length of a belt, feeling on existence of cracks and stratifications. Also check whether is not present on a belt of attritions and sites, zapolirovanny to gloss. The belt has to be examined on both sides that means need of its twisting for check of a condition of inner side.
9. 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, then the size of a deflection 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.
10. In the presence of one or several of the specified damages maple the belt needs to be replaced on new, at the same time address the subsections Removal and installation of a ridge maple belt and Removal and installation of a maple belt.
11. Establish into place a side cover of a motive compartment.
