17:12. Check of a state, adjustment of a tension and replacement of driving belts
Two times a year or each 10 000 km of a run (that will come earlier)
Check of a state
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.
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 several components at once.
In need of adjustment of a tension of a belt towards its increase or reduction it becomes by movement of the unit given by a belt on its fixing arm. In that case when the belt puts more than one unit in action, usually for its adjustment there is enough shift of only one of them.
Often for movement of the unit for the purpose of adjustment of a tension of a belt it is necessary to use the lever. If it is necessary, act extremely carefully not to damage the moved unit or the element used as a point of support.
For replacement of a belt follow the instructions for adjustment given above, but at the same time take off a belt from pulleys.
In certain cases you should take off more than one belt because of features of their arrangement in a forward part of the engine. Therefore and also because belts tends to fail at the same time, it is the best of all to replace them at the same time too. Mark each belt and the flute corresponding to it on a pulley correctly to establish new belts.
Upon purchase of new belts it is convenient to take with itself old to have an opportunity directly to compare them on length, width and design.
Check a tension of new belts after the run of several hundred kilometers.
