Install the generator drive belt in the reverse sequence and adjust its tension. To accurately check the belt tension, you must contact the service.

What is this service?

The drive belt connects the generator, the steering hydroeviller pump and the air conditioner compressor with the crankshaft pulley of the engine, the belt transmits power from the engine to these nodes. In the absence of this belt, the battery will not be charged, and none of the electrical components of the car will work. Due to the high temperature of the engine, with time the belt can crack and break. When breaking the belt, the steering wheel will be difficult to rotate, and the control of the car will become dangerous. In some cars, the cooling system pump is driven by a drive belt. When the belt is destruction, the cooling fluid circulation required to maintain the proper engine temperature is disturbed. The engine will overheat, which can lead to its serious damage.

Drive belts are an important part of the power plant, and as any part of it are susceptible to wear. To avoid problems when working a car, replacing the drive belt Must be committed immediately after detecting suspicion of malfunction. Otherwise, it is possible to fail by many aggregates up to their breakdown, and as a result, expensive repair.

Drive belt functions

Depending on the car model, several drive belts can be used in it. Their main task is to move a large number of aggregates, among which the generator, compressor and steering pump are the most important.

Usually the driving belt malfunction does not lead to an immediate stop of the machine, most likely you will be able to get to the house or a hundred. In this case, it is impossible to postpone the repair, because in this case the generator will not work, and the cooling system will not be able to remove heat from the engine.

How to replace the drive belt?

If you have the necessary skills, you can perform such a procedure yourself. To do this, you need to read the documentation for the car, buy the necessary equipment and make a replacement. Naturally, this requires certain skills, without which it is better to trust this business professional.

Relief belt replacement price More than affordable, so it is easier to cause mechanics and make more useful things. If you do not know when this procedure was last made, then before, inspect it visually for the presence of defects, it may be at all and is not required. Specified in the operating instructions for the vehicle - you should not imply this service.

Keep in mind

The car can be equipped with flat or wedge drive belts. Flat belts may be one or two. Most modern cars have only one belt, which brings all engine attachments. If the car is equipped with wedge belts, they are usually four pieces.

The mechanic must check the condition of the drive belts when the engine oil is replaced. If you hear the squeezing sound from the engine compartment, it is most likely to adjust or replacing the drive belts.

How important is it

The break belt can damage the important parts of the car and expensive repair. Therefore, as soon as you notice the deformations, breaks, cracks or other belt defects - it should be replaced immediately.

The main reasons why it happens

• Whistle under the hood from drive belts
• Power steering does not work (torn strap)
• Battery malfunction indicator
• The engine gets very hot

List of basic works:

• Check the belts for cracks.
• Remove and replace damaged belts.
• Examine rollers and bearings.

Each driver faced an unpleasant moment of the belt cliff in the engine. Consider the possible moments of replacement, which is necessary for this and what are the consequences if you understand the replacement of the belt in time.

The content of the article:

The transmitter belt is not a small part in the car engine, as the turnover from one working mechanism is transmitted by another mechanism. An example of such a mechanism can be a generator, a steering hydraulicer, most often recall the belt, which is in the gas distribution mechanism, is called the timing in a different way.

The belt is often made from a special rubber-tissue composition. This is done in order to be elastic when working, and strong at the expense of fibers. But not everything is forever in our lives, therefore such mechanisms have a property break. If the belt is torn in any of the mechanisms, then it is significantly very much, the car or stalls right away or disappears.

Generator belt, how to change

If the generator belt we will and you pulled it up, then it will not for a long time, through time the situation will repeat, therefore it is recommended to replace it with a new time in the near possible time. And so, the replacement of the belt begins with the fact that the tension should be loosen. To do this, unscrew the nut of the tensioner bolt. Often it is located near the generator and allows you to freely move the generator in the direction of the belt. After the belt loosened, remove it and change it to a new belt, stretch, but also it is not necessary very much, since it is extended much faster than it is supposed.

I recommend it in advance to make a mark near the tensioner of the generator, in which position it was initially, it would be easier to determine and stretch the belt to the desired position. To understand what was wear, you can compare the new and old belt from the inside. On this, the replacement of the generator belt ends.

How to change the steering hydraulic belt

In such a situation, it is better to look at both belts, since the one and the other can at the most inappropriate moment you will be brought in a long road. Now we put a new steering for the hydraulic power steering, tighten up to a predetermined mark, are similar to the generator belt. After such a replacement, it is worth the engine and give it a bit of load to listen to whether the belts of the hydraulic and generator do not whistle.

According to safety, as well as in any other case, it is advisable to spend everything on a cold engine, since you will directly work with the details that quickly heat up from the engine.

We change the belt of the gas distribution mechanism (timing)

It is impossible to say that he covers only camshaft and crankshaft, he also goes through the auxiliary units, but it already depends on the brand of the car. Alas, such universal work does not lead to good, wear is much faster. Often the belt breaks simply due to the fact that the driver ignored it on time to replace it. The belt replacement itself is not a complex process, but also not in 5 minutes. Before proceeding, preparatory work should be made.

I exhibit marking on the belt, the label on the crankshaft and the pulley, as soon as they coincide, you can safely change the old timing belt to the new one. It will not be superfluous during the replacement of the timing belt, just look at the glands of the crankshaft, camshaft, stretch roller and water pump. Since they can also influence the belt wear.

Price of the new belt and work

The cost of the belt will be in the first place from the brand of your car, and the destination, so, for example, a 3-4 $ can cost the generator of a domestic car, for the hydraulicel somewhere 4-4 $, but the timing belt will always be more expensive Since it is the main in the engine, it will cost about $ 7.

Replacing the timing belt will cost from 3500 r., The belt of the generator, air conditioner or the hydraulic agent will cost from 350 p. The price does not include the price of the belt itself.

Some car manufacturers provide possible cases of the timing belt break at any time, therefore such engines use special protective mechanisms, they protect the engine from obtaining mechanical damage when the belt is torn. In personal practice, I can say that in the Opel car engines with a volume of 1.8 liters, when the belt breaks, the valve is immediately oppressed, because they do not use in excellent drivers, but with a volume of 2.0 liters have protection already from such a breakdown.

Video about the replacement of the timing belt:

The main problem with the wear of the drive belts at the initial stage becomes various symptoms and suits during the rotation of the pulleys transmitting to the engine attachment. In the event of creak and whistles in a short time, one of the drive belts may break. We offer you detailed information about these types of belts in modern cars. Our directory will help you to know when it is necessary to change the drive belts, how to determine the degree of their wear, what is the difference between the drive belt and which is the average cost of drive belts on the Russian market, as well as get answers and other issues related to these belts.

First, let's put all the points over "I", finding out what drive belts are.

Drive belt car - This is an element of belt transmission, a working part of vehicles and mechanisms that serves to transmit torque engine.

The transmission of torque occurs due to the friction forces or the forces of the engagement (gear straps, wedge-shaped belts).

There is an erroneous opinion that it does not apply to drive belts. But actually it is not. The timing belt also refers to the category of driving belts.

Drive belts are divided into several types:

Timing belt (belt drive gas distribution mechanism)

Drive belts of auxiliary components (engine attached equipment)

There are three types of automotive belts:

Thanks to the rotation of the generator, electricity is produced, which supports the work of the entire electrical equipment of the car.

Also in many modern cars, the same belt type is used to transmit torque on an electric power steering amplifier, the cooling fan, on the water pump (coolant pump), on the air conditioner compressor and on the classic steering wheel hydraulic. Since the belt is subjected to colossal load and constant temperature drops, it is usually made of a rigid rubber and a metal core, which ensures the strength and durability of the belt. Also, many belts have a durable textile thread allowing a high torque to withstand a belt.

So every car besides the timing belt (in some cars, the gas distribution mechanism circuit is also used) has one or more belt drives (depending on the technical features of the car), ensuring the performance of the engine attachment.

If the drive belt has cracks (consequences)

If your car (or belts) wear out, they will have on the surface of the crack and scuff. As a result, a whistle will begin to appear during their movement. In this case, the time of their planned replacement has come. Remember that if you do not change the drive belt during, then you risk staying without workable car equipment. For example, if the life of the belt has expired due to serious wear, it is sooner or later will naturally break.

As a rule, when breaking the drive belt, you will hear a loud cotton from under the hood. As a result, the equipment that received a torque from it will cease to function. For example, if the drive belt is broken, the supply generator will stop, then it will stop and feed all the electric equipment of the car. In the end, you will see the battery icon on the dashboard on the dashboard.

Also from the belt cliff will stop the hydraulicel. As a result, your steering wheel will rotate very hard. But the main problem when the drive belt break is the absence of rotation of the water pump, which contributes to the circulation of the coolant on the engine cooling system. As a result, the engine can quickly overheat. In this case, you must immediately stop moving and turn off the engine.

Therefore, while driving, constantly monitor the engine temperature sensor, which should show the same temperature of 90 degrees. If you see that the temperature arrow went up and approaches the dangerous red zone, then it is necessary to stop and, turning off the engine to diagnose the cooling system.

Attention! Overheating of the engine can lead to its failure (damage to the oil-circulation cap, failure of the block gasket, damage to the piston system). Therefore, do not allow in any case controlling the engine temperature on the dashboard.

What does the service life of the drive belts depend on?

Modern drive belts have enough due to their design from modern reliable materials. On average, the quality belt can serve up to 25,000 hours of operation. Please note that the service life is specified in the clock, and not in kilometers, since the kilometer does not directly affect the service life of the drive belts. After all, these belts are in motion even when the car stands still, and the engine is working at idle.

But this is in theory, and according to information provided by manufacturers of belts for consumers.

In practice, the service life of the drive belt may differ significantly from the manufacturer's declared. The fact is that many factors affect the wear of the drive belts. For example, an important role in the long service belt serves as it was installed on the car. For example, not uncommon when trying to plant a strap on the pulley with a screwdriver. As a result, the new belt is damaged and will not be able to serve that the term that the manufacturer declares. Such a method for installing the drive belt is also used to speed up the replacement process so as not to remove the pulley.

In addition, for the service life of the belts affects the storage conditions of components in the warehouse and their transportation. For example, it is not uncommon when in the auto shops sell drive belts with an expired shelf life. Yes Drive belts have. The fact is that the chemical composition of the materials of the drive belts changes over time. And if the drive belt was produced 5 years ago and was incorrectly stored in the warehouse, then when it was installed, it will not last for a car.

Also on the durability of belts in the car can influence the weather. For example, if you live in a hot climate, then you often use air conditioning. This means that the air conditioner compressor should receive. As a result, the belt transmitting the torque on the air conditioner compressor is experiencing an increased load.

Including driving belts can quickly wear out if the car is operated in cold weather for a long time. For example, in winter, the electrical equipment of the machine is required more nutrition than in warm weather.

As a result, the generator requires more energy to maintain the operability of the power grid in the vehicle. As a result, the generator belt is experiencing an increased load due to an increase in torque.

As a rule, in a new car, drive belts serve longer, since all the necessary storage conditions were met in the factory and before installation. After replacing the factory drive belts, the life of the belts is reduced.

Each automaker in the technical documentation and the service book typically indicates regulatory work when it is necessary to plan to replace the drive belts. Therefore, we advise you to carefully read the list of planned technical inspections and regulations for replacing consumables. As a rule, the manufacturer indicates a limiting kilometer, in which the drive belts should be replaced in the Master Technical Center. Thus, you approximately learn the deadlines for drive belts. But this does not mean that you should not regularly inspect the state of the belts. About this below.

Regular verification of drive belts

Periodically, each car owner must check the condition of all drive belts and their stretch. To do this, it is necessary to check the belts with your finger at the engine turned off. For example, by pressing your finger on the belt, you can understand whether the belt drive is weakened. Remember that the belt at the same time does not have to move (shift for 1-2 cm). If you see a similar one, then the blame is a weak belt stretch. You should also touch the belt to damage. Visual inspection is also needed on the subject of chips, cracks and ribbon elements.

In addition, use a pocket flashlight that will make an overview not only better, but can help reveal the lighted belt areas (as a rule, the belt portion will be blushing).

In any case, if you see damaged strap areas, then it must be replaced in any case to a new one. Please note that purchasing new drive belts you do not need to acquire original consumables. There are many non-original belts on the market, which in quality often even exceed the factory originals. For example, Continental has proven perfectly well, which is the largest supplier of drive belts.

The average cost of replacing the belt in the auto repair shop is about 2500 rubles. The belts for the car depends on the fame of the brand and the cost of products. The market is present, both cheap drive belts and expensive, which have a special design and are able to withstand extreme loads.

How to pull, tighten or loosen the drive belt

If the cause of the whistle, squeal or the screens is the belt, which is weakened, as a result of which he slipped on the pulleys, if the belt does not have or damage, in order to remove the outside sound, you must tighten the belt.

On the example of the belt, the generators are done using an adjusting special bolt (on modern cars) or using an adjusting plank (on older machines).

For example, to pull the generator belt on a modern car you need to do the following:

- Loosen a little fastening bolts of the generator (upper and lower fastening)

- Turn the adjusting bolt towards the time of the clockwise, the removal of the generator from the engine block and immediately checking the belt tape level

- Then staring the nuts of the fasteners of the generator

Please note that in some car systems, the process of pulling belts, too time-consuming and requires the use of a special tool.

Attention . In the market and in many cars at the moment, the spread of a new generation of polyclinic elastic belts was obtained. For example, one of the well-known global manufacturers like belts is ELAST. Their products have proven themselves in the best way. This company is the official supplier of many auto plants. Elastic polyclinic belts do not require stretching and pulling, etc. Thanks to their design and material, such belts are not stretched. As a rule, such drive belts serve about 120,000 mileage kilometers.

But for its initial stretch, a special tool is required.

In many cars, special belt tension rollers are also used, which eliminates drivers from constant tightening belts. The only drawback of such a design is, as a rule, when replacing the drive belts, it is also necessary to change the tensioning roller, since it is not possible to reuse with the new belt.

Replacing drive belts in the technical center

How can I replace temporarily drive belts in the event of a vehicle breakdown on the track?

Unfortunately, to temporarily replace the drive belts in case of climbing on the track, in modern cars it is impossible. In old cars, with such a problem, women's tights sometimes helped. But these times went away. When cutting the drive belts you will need technical assistance.

Car belts are among the most important details. And, like all other moving parts, they eventually fail. Therefore, the owner of the car must be able to do two things. The first is to determine the need to replace the belt on time. And the second is to be able to change it yourself.

Drive belt functions in auto

It is necessary to clarify: in the car there are several drive belts. The function has one - the transmission of rotation from the engine to other machine units.

Exemplary list of aggregates:

• Electric car generator;
• Pump cooling system;
• Air conditioner pump;
• Oil pump;
• Pump power steering.

A set of aggregates associated with the motor drive belt may vary. It all depends on the car model. Exception - the drive belt of the generator. It is always available on any car. Therefore, the replacement procedure should be considered on its example.

What is the purpose of the generator drive belt? Transmission of rotation from the engine. The generator coil rotates in the process of which electricity is created, charging the machine battery. If the item fails, the generator stops work. The battery is discharged, and the car will stop. And if there is no socket and charger at hand, the situation will be very unpleasant.

The need for replacement

But how to understand that you should change this drive detail? According to the regulations, the procedure is carried out every 50-60 thousand km of run. With a small run, the replacement is made every 5-6 years.

But with certain signs, the replacement is immediately carried out:

• Whistle under the hood. At the beginning of the ride - weak, barely audible sound. With an increase in the load on the engine, the volume is enhanced. In the case of the generator belt, the volume rises and when the additional electrical appliances are turned on. If the cooling system pump drive is wearing, the whistle appears when overheating. And in the case of a hydraulic switch, the whistle appears with sharp turns.
• Weakened drive tension. Check simply - you need to pull the middle of the ribbon aside. He must move away from the previous position for no more than 10-13 mm. Accurate tolerance is specified in the service book. If the distance is greater - the tension is weakened. Detail must be either drawn or change.
• The belt is damaged. There is enough a quick inspection of the detail. Cracks, breaks, fibers of fabric and holes on the items are talking about the ambulance. In the described case, the replacement is required.

For the obligation of replacement, it is said that failed in the work of the relevant nodes:

• In case of fault, the cooling system pumping system is constantly overheated by the motor.
• When problems with the belt of the hydraulicer, the steering wheel is hardly rotated.
• With a weakened actuator, the air conditioner in the cabin becomes hot, or cold - if the belt failed in winter.
• In case of problems with the generator drive, the devices are burning dim. Engine starts with difficulty.

How to replace the drive belt with your own hands?

First, a suitable belt is purchased. It is worth considering: the inappropriate item will quickly fail. Moreover, the gap does not precede whistles and other signs of wear.

Therefore, there are a number of important criteria when choosing a detail:

• Dimensions and quality. And it is necessary to watch not only for length. The width and thickness are also taken into account. It is worth paying attention to the material used in the manufacture of the part.
• Manufacturer. Do not try to put a belt from another model on the car. The replacement is allowed when the manufacturer is officially confirmed. Checked on the service book, or from the official supplier.
• The belt is suitable for this node. Example: The driver is trying to put a detail on the generator from the steering hydraulic poweror. It does not lead to anything good.

As an example, the procedure for replacing the generator belt is taken:

1. The fastening of the generator on the support is weakened. The generator itself is moved closer to the engine.
2. Detail is removed from pulleys. If necessary, the key turns the key, in order to release the belt. Pull it should be careful. It is worth remembering - in the presence of breaks, the part clings for various nodes and mechanisms.
3. Install a new belt. It must be consolidated in the same form as the old one was installed.
4. All removed parts are returned to the place. The generator returns to the previous position. We must remember: you have to pull the belt. And with the new item it will not be easy. Here will be required assistant. Its task will be the hold of the generator in the desired position.

If the belt is replaced for other nodes, the procedure is similar. Cables and parts interfering with access are removed. The belt tension weakens. Example: In the case of an air conditioner, the compressor is removed. The old detail is removed, the new one is set. Then everything is put in place.

Possible difficulties

The described replacement is not considered a complex procedure. But it is associated with a number of problems. They are divided into two groups: manifested in the process and after replacement. First you should deal with the problems of the first type.

When working, the following difficulties arise:

• Inaccessibility of aggregates. Cars are designed not for repair at home, so a number of aggregates are difficult to remove due to the design features. In the worst case it is impossible to do without special equipment.
• Parts of the old drive block adjacent aggregates. Example: part of the part is confused in the wiring. Solution: parts are removed and removed. It should be removed carefully.
• New belt insufficient length. In certain situations, the difference is 2-3 mm. And before installation, it is invisible.
• The failure of the drive rollers, cracks in the axes. Corrected by replacing the corresponding parts.

But it is worth remembering: when repairing other problems can occur. It all depends on the car model and the character of the breakdown.

Problems arising after replacement:

• The incorrect work of the unit. With incorrect transmission of rotation, there are problems with the engine. Solution: Reinstall the part.
• The engine does not start. If the drive is too tight, it interferes with the rotation of the motor. Resolved with a relaxation belt.

There are only two of them, but they are enough to spoil the life to the driver.
