Condition check drivers ridge belts

1. The 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. The privodnye belts sometimes named belts of V-shaped section or it is simple вентиляторными belts, are in a forward part of the engine and play the important role in work of the car and its separate components. Because of features of a material and operating conditions приводные 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. Privodnye belts are applied to actuating of the generator, the steering pump, the water pump and the compressor of a 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, establish РКПП in neutral position. Lift and establish the car on supports.
5. Remove the bottom cover of an impellent compartment, address to subsection Removal and installation of the bottom cover of an impellent compartment.
6. Mark a chalk a belt–1 on good a foreground.
7. From the bottom party of the engine a head turn the engine for a pulley of a cranked shaft in a rotation direction, i.e. in the right party so that cretaceous marks were visible. Thus a site behind a site see a belt.
Deterioration of edges of edges of a ridge belt
Cross-section cracks D from an underside of a belt and отслоение edges Е of a ridge belt
Разлохмачивание lateral edges F, crack Н and отслоение lateral edges G
Separation of edges J, cracks K
8. Fingers (and using a small lamp if it is necessary) walk on all length of a belt, feeling on presence of cracks and stratifications. Also check up, whether is not present on a belt of attritions and заполированных to shine of sites. The belt should be examined from both parties that means its necessity перекручивания for check of a condition of a seamy side.
9. The belt tension is checked by strong pressing on it by a thumb and definitions of degree of its deflection. Deflection size measure by a ruler. If the distance centre to centre pulleys makes from 180 to 280 mm the deflection size should equal 6 mm. If the distance centre to centre pulleys is in limits between 300 and 400 mm, the deflection should be 13 mm.
10. In the presence of one or several of the specified damages клиновой it is necessarily necessary to replace a belt on new, thus address to subsections Removal and installation ridge клинового a belt and Removal and installation клинового a belt.
11. Establish into place a lateral cover of an impellent compartment.
