Condition check приводных belts

Condition check

Приводные ridge 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.

The quantity of the belts used on the concrete car, depends on the units established on it and systems. 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.

 PERFORMANCE ORDER

1. Switch off the engine, open a cowl and find various приводные 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 presence of cracks and stratifications. Also check up, whether is not present on belts of attritions and заполированных to shine of sites. Each belt should be examined from both parties that means its necessity перекручивания for check of a condition of a seamy side.

2. 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. The thumb rule says that 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.
3. Deterioration of lateral surfaces: a point of edges (), at a new belt of an edge have трапецеидальную the form.

4. The pulling branch of a belt is visible in the basis of edges. It is defined in more light places.

5. Presence of cross-section cracks (D) on a belt underside.
6. Отслоение separate edges ().

7. Разлохмачивание external plaits of a belt (F). Address to an accompanying illustration.
8. Lateral having dug a plait (G).
9. Presence of cross-section cracks (H) in many edges.

10. Breakages of edges (J). Address to an accompanying illustration.
11. Separate cross-section breakages of edges (K).

12. Adjournment of a dirt and stones between edges.
13. Rubber outgrowths in the basis of edges.
14. In the presence of one or several of the listed defects the belt should be replaced, address to Section Removal, installation and a tension клинового a belt.
15. Check up a belt on ageing on presence of cracks. In the rest the belt does not require service.
The klinovoj belt stretches automatic натяжителем. To check a belt tension it is not required.
