In every belt engine front several belt, assume an important role. On the engine, through the belt drive drive auxiliary machines run, such as air conditioner compressor, power steering pump, alternator, etc. If the fracture belt, or a skid, will make the related loss of auxiliary function, or performance degradation, thus affect the normal use of car. Old heavily damaged belt, belt and pulley contact area collapse. At this time as long as hard a pressure belt, belt is deeply sink to the pulley groove. Belt rubber aging remains a problem, if the belt rubber serious aging, new belt need to be replaced in a timely manner. Belt inspection method is very simple. First check the belt tension, then can use thumb, strength to press the two pulley in the middle of the belt. According to the pressure of about 10 kg, if the amount of pressure belt around 10 mm, argues that the belt tension on the right. If the reduction is too large, the think of belt tension. If the belt is hardly appear reduction, the thought of belt tension is too large. Tension is insufficient, the belt slippage can occur easily. Tension is too large, it is easy to damage all kinds of auxiliary engine bearing. Therefore, should take relevant adjusting nut or bolt loosen, adjust the belt tension to zui better condition.
