Automotive Likbez: Generator belt from A to Z. Detailed instructions How to change the generator belt generator belt where is located
Thanks to the drive belt, the torque is transmitted from one mechanism of the car to another. On the modern cars Multiple drive belts are installed, but each of them plays a very important role in the overall performance of the entire car. The gap or weakening of the drive belt can lead to the fact that the car can not be started at all. In this regard, each driver must understand and know how the car belt drive is replaced. In today's article, we will talk in detail about what reasons drive belts may fail, and on the example of the timing belt, consider the replacement process at home. Special attention to be paid to what problems usually have to face car owners during the replacement of drive belts.
1. What is needed to replace the drive belt, and what types of this item are installed on the car.
As we have already noted in the accession, several types of drive belts are usually installed on cars. According to the purpose and functions that perform drive belts, they should be divided into the following two groups:
- Belts that are responsible for the operation of the drive of the car's gas distribution mechanism (i.e., timing belts);
Belts that provide all the rest auxiliary aggregates car.
But according to the structure, all drive belts a passenger car It is customary to divide into three groups:
- gear, which are often used on the drive of the gas distribution mechanism;
Polyclinic or flat, which are used only on auxiliary aggregates;
Wedge or wedge-shaped are also installed only on auxiliary aggregates.
Consider the features of the drive belts on specific examples.
Purpose I. distinctive characteristics Belt distribution mechanism
This element transmits torque from the crankshaft to distributional shaft car. The rupture of the timing belt can lead to very negative consequences:serious damage to the valves, pistons and even the engine cylinder block. In this regard, this element imposes very high requirements for its reliability and durability. After all, damage is quite cheap vehicle belt can cause very large-scale costs of purchasing a new engine, which certainly does not want any car owner. But still, the timing belt is able to wear out over time. To prevent this, you need:
1. Installing the car only original products and in no way acquire a cheap Chinese counterfeit.
2. The process of replacing the timing belt must be treated with full responsibility and very strictly follow the recommendations of specialists. This also applies to how often the replacement should be replaced, and to how it is necessary to set the timing belt marks.
3. Simultaneously with the replacement of the timing belt, it is necessary to install new stretch and guide rollers. These elements are able to wear it intensively, like the belt itself.
4. It is very important to lead the so-called "onboard diary" of your car, in which it is recommended to record mileage after each replacement of the timing belt. So you can not miss the term of the next replacement.
5.
When buying a used car, the timing belt replacement must be carried out necessarily. I assume the previous owner that everything is new on his car, it is impossible to take seriously.
Where else can drive belts be used?
- belt hydraulic steering wheel;
The generator belt, which is installed on the automotive battery;
Vehicle air conditioning belt;
Engine water pump belt.
Despite the fact that the rupture of belts of auxiliary aggregates cannot lead to such serious consequences as a rupture of the timing belt, such a situation is still able to bring a lot of trouble to the car owner. For this reason, the replacement of these belts should also be carried out on time. As for what type of belt is better to install, then we will make a comparison specifically for you:
1.
Wedge-shaped belts of auxiliary aggregates today are practically not used, although they have a number of explicit advantages. They are relatively cheap and easy to install. Such a belt can only be installed on one unit and, if it is broken, all other devices continue to function normally. Instead of tension and guide rollers to install a wedge-shaped belt, conventional pulleys can be used, which are simply shifted against each other.
Previously, the drivers managed to even put an ordinary rope instead of such a belt if there was not enough time to implement a full-fledged replacement. But in general, wedge-shaped belts wear out very quickly and require periodic adjustment of tension, which is sufficiently impractical for continuous operation on modern cars.
2. Polyclinic belts are usually found on modern cars. They are durable, the degree of their tension can be adjusted automatically using roller tensioners, they are able to withstand a much stronger load. But it is logical that such belts are more expensive than wedge. Also in the process of replacing the polyclinic belt have to be spent on the purchase of new rollers. If such a belt breaks, the further operation of the car becomes impossible.
As you can see, a unambiguous answer regarding which belt is best to choose for your car, there is practically no. Moreover, manufacturers sometimes specifically increase their cars by setting on it a more expensive alternative, although there is no need for it.
Factors that lead to wear and burst drive belts
Name the specific service life of the drive belt is simply unrealistic because a large number of different factors can affect it. If on one car the need to perform such a procedure may occur after a month, then the driver will be able to drive with the same belt for two years. It depends on:
1. The originality of the product. Native drive belts usually serve longer than universal and, especially, cheap Chinese. In any case, the belt must be selected for the car model. In the middle, the service life of any drive belt is about 65,000 km of run.
2. Operating conditions. In this case, not only the road covering is important for which you have to ride a car, but also the driving style of the car owner. The more often the car is operated, and the more intensive it is necessary to work with its units, the faster the drive belts will wear.
3. Age of the machine and its units. The older the aggregates - the more often the belts have been replaced. Thus, the replacement of the drive belts should be carried out not only if they are ruptured. Rather, this cannot be allowed. It is better to start a replacement at that stage when the first signs of wear and the unit were manifested on the belt, or the unit, for whose work he answers, began to work not entirely correctly. In this case, it is necessary to begin preparations for replacing the drive belt.
What is needed to replace the drive belt?
A set of tools required for replacement is very small, and it can be found in any garage of the car enthusiast. In particular, you will need:
- set of wrenches;
Cape keys;
Jack;
Screwdriver;
Scattered head;
Drills or screws (need small sizes tools);
End key.
2. The process of replacing the drive belt of the car: detailed instructions.
We will tell you this process on the example of the replacement of the timing belt. We drew attention to it for the reason that its installation is most responsible and includes a lot of important nuances, such as the correct setting of tags.
Before you begin work, you need to remove the terminals from the car battery (at least turn off the minus). Also, during the implementation of the replacement, in no case should not twist the belt, as it can lead to the failure of its labels, after which, even with a new belt, the car can not start at all. So, proceed to replacing the drive belt of the gas distribution mechanism:
1. Remove the fastening of the belt of the belt of interest to us. To do this, use conventional wrenches, as it is attached by conventional bolts.
2. We unscrew the most upper fastening bolt of the generator, which will allow you to remove the unit to the side so that it does not interfere with further work.
3. Remove the generator belt. Make it will be very simple, because after removing the attachment from the unit and its movement, this belt was supposed to weaken. If necessary, it is also necessary to replace it.
4.
Now you need to properly adjust the labels of the gas distribution mechanism. To do this, we include the highest transmission of the car and very slowly turn the crankshaft until the labels on its gear do not match the tags on the clutch housing. In addition to labels on the clutch case, it is also possible to focus on the metal bar installed on the engine.
5. Weaken the roller that pulls the timing belt, and remove it.
6. By securely fixing the labels of the crankshaft so that they do not get down, we unscrew the fastening bolt of the pulley.
7. Fully remove the timing belt.
8. Remove tension roller And install a new one instead. Not excess will check the gear. If it lacks the teeth, it should also be replaced with a new one.
9. Turn face to right board, take in your hands new belt Timing and expand it in such a way that all inscriptions have been turned to you.
10. Install the belt, starting the installation from the bottom gear, then, continuing to hold the tension, it must be hooked behind the upper gear and for the pump gear.
11. Back to install the pulley and a new tensioning roller.
12. We set all the elements removed from the car in the reverse order.
On this replacement process ends, it remains only to check the power of the tension of the new belt. For this belt, you must try to turn in the stretched place. The belt reversal angle should not be more than 90 °, otherwise the installation will be considered incorrect and unfinished.
3. Frequent problems when replacing the drive belt.
Despite the seeming ease of installation of the drive belt, many drivers have this task causes a whole mass of problems and difficulties. First of all, they may be associated with the correctness of marking tags (if it comes to the gas distribution mechanism belt). In this case, work car Engine It will be very unstable, they will constantly fall momentum or they cannot be enhanced. There are no cases when, due to the wrong placement of marking, the car does not start at all.
In such a situation, the rational all will appeal to specialists in the car service, since if you have not happened to cope with this task, it is better not to risk. Moreover, you can ask to observe the work of professionals and consult with them in a similar question.
But how to find out what you missed drive belt? First of all, it will be noticeable in the absence of "signs of life" of the unit, whose work is responsible for the belt just installed. If we are talking about the timing belt, then you will definitely inform the "Check" lamp.In addition, there are some more accurate features that will indicate the malfunction of the timing belt:
- When starting, the engine begins very significantly and dangerously vibrating;
Under the hood in the engine zone and its units, an unpleasant knock is heard;
Engine works, but it is observed increased flow gasoline;
Different parts of the engine, including the drive belt, the gas distribution mechanism began to wear very quickly.
All this once again confirms the fact that the replacement of drive belts is better to trust specialists. After all, the breakdown of such an element can lead to very unpleasant consequences, Including the failure of the car engine. We hope that our advice will help you avoid a similar fate.
Replace the generator belt on their own - is completely simple even for those who do not have the experience of repairing the car. This lesson will be very useful for newbies.
When is the replacement of the generator belt?
At least because it will be possible to study the device of your vehicle movement and the principles of all its mechanisms.
Wizards with experience would be called the replacement of the belt "ABC", but without these Azov, in the future, simply nowhere. Before you begin to replace this element of the engine, it is for sure to make sure that it is the belt, and not something else, failed.
Where is the generator belt? Look for it under the hood, on the left side of the motor when you become face to your car. Before you begin to inspect the part, you need to turn off the motor, the ignition key to remove, and disconnect the car from the battery negative wire.
After that, inspect the belt for the presence of wear signs. They become cracks and ruptures, stretching or loss of elasticity. If the generator belt is worn, it does not look, then try to check its tension. Usually this reason is the reason for incoming engine work.
Replacing a belt generator
In most cases, the belt will still have to change, because the cracks clearly nobody becomes. To do this, it is enough to go to any auto shop and acquire exactly the same belt. To remove the old spare part, first need to weaken its tension. Take the key and scroll the tensioner bolt nut. Finding out where the last one is located and how it is arranged, you can proceed to the next stage.
The tension mechanism can be in the form of a bolt or a semicircular rail, which depends on the car model. Before removing the old belt, also remember, for which it clings and how attached. A new spare part should be installed in the same sequence as you removed the old. For the first time, you can quickly draw a small scheme on the paper sheet or paint the procedure for your actions.
In the case when the belt holds the bolt, it is unscrewed, spinning into one or the other side. The tensioner differs from other bolts in that it is not necessary to unscrew it. Having made a couple of revolutions, you will feel how the generator belt began to weaken. Having defined on the eye when you can remove it, - leave the bolt and perform the right action.
If the new belt is set incorrectly or inaccurately, then the problems with the engine operation are guaranteed. That is why even such a light, at first glance, work requires accuracy and caution. By installing the replacement with the old strap, connect the negative wire to the battery, then start the motor. By running the engine, let the largest, but permissible, the load on the electronics, turning on, radio and heating, and also a little repayment.
If a whistle is again distributed - it is not necessary to be afraid: just do the same actions that were described before, and reinforcing the tension of the generator belt, as well as it is necessary.
Replace the generator belt is easy, it can even be a novice car enthusiast. Replacing the belt gives an excellent opportunity to explore the car's device, and begin to understand its mechanisms.
You will need
- - New generator belt, similar to the old
- - set of wrenches
Instruction
Before changing the generator belt, you need to make sure it is unsuitable for use condition. The main feature that the belt is a characteristic whistle that appears when using electronics. Also about malfunctions with the generator belt, you can learn from the indicator signal. There is a generator belt under the hood on the left side from. Before starting replacing the belt, you must disable, pull out the key and disconnect the negative wire from the battery. Then it is necessary to inspect the belt for cracks, breaks, exhaustion. If there are no such signs, then the belt tension should be checked.
Before replacing the generator belt, you need to purchase a new belt similar to the old one. In order to change the belt, it is important to start weakening the tension to remove it it was easier. It is necessary to carefully examine how the tensioner is arranged and where it is located. It usually looks like a stretch bolt or semicircular rail, depending on the car model. It is very important to explore the location of the belt and the sequence of clutch, the new belt will need to be installed as well. If the tension in the car is adjusted with the help of a bolt, then you need to pick up the key suitable in size and turn it into one or the other way. You don't need to completely unscrew the bolt, it must be simply unscrewed so that the belt is weak, and it could be easily removed.
Car generator belt Gazelle Business is responsible for the transfer of engine rotation to the auxiliary to its units. Some devices are capable of moving several mechanisms at once.
The drive belt can affect the pump, the hydraulic power steering pump, various compressors and even the generator. In order for all the above mechanisms to work simply and smoothly, it is necessary to replace the parts in a timely manner, and if necessary, adjust its tension. In today's article, we will look at: where the belt is the belt of the Gazelle Business generator, signs of its wear, dimensions, scheme and step-by-step instructions Installation. Well, what to proceed.
Location of the belt Generator Gazelle Business
The generator belt on the Gazelle business is located under the hood in the front of the car! As shown in the screenshot
It's easy enough to find it, so at this moment I will not sharpen my attention and your attention.
Gazelle Business - Signs of Generator Belt Wear
In order to find out how much the generator belt on Gazelle business is enough to have its visual inspection. If you notice:
- Oversight
- Surface detachment
- Mechanical damage, etc.
I do not delay the replacement of the drive belt in a long box, and immediately replace this consumage.
Belt Size Generator Gazelle Business
Gazelle business, as well as any other car domestic production It has a lot of inconvenience, for example, the generator belt installed from the manufacturer's plant under the labeling: 8pk 2155 or 8pk 2166 has small size, so when replacing it to put it in place almost impossible!

Installing a belt of the generator on the Gazelle Business Step-by-step instruction
In order to replace the generator belt on the Gazelle Business to need to perform the following step by step instructions:
- Ratchet grind the drive belt through the pulley of the generator
- We use the belt on the pump pulley from the engine and rotate the ratchet pulley of the generator clockwise:
- Intercepting after a small belt gathering, we continue to gradually rotate the pulley of the generator:
- We seek and throw off the old belt of the generator
- Take the belt in all the rollers, wear all the streams on the pulleys! We only leave the pump pulley not dressed. The tensioner does not touch at all, and the meaning, the move is small and does not allow you to freely wear a belt.
- We take everything out the score and feed her belt on the pulley pump in the tension! And gradually rotate the ratchet clockwise! It is important that the lower edge of the belt rearranged through the Pump Pump Center:
- The main thing is to keep scolding and not to let her go until the belt wrap the pulley!
- You can not remove the radiator and remove and remove the belt normally. The only thing that is exactly the replacement of the belt, it is more difficult to block it through the impeller and everything.
One more important moment which would like to draw your attention - tension belt generator ! In order to accomplish this job we will need:

Replacing the belt Generator Gazelle Business DIY - Video
Maintaining the appropriate voltage in the onboard network of the car while working power plant Lies on one of the elements of the electrical equipment of the auto generator. The generator is the same electric motor direct currentwhich works on the contrary. If the engine rotates the rotor at the expense of the supply of electricity to it, the generator generates electricity from the rotational rotational motion. So that the generator generates energy that will power the auto network network, it is necessary that its rotor rotates.
A constructive solution to ensure the rotation of the generator rotor, as a result of which it produces electricity, has become a drive from the crankshaft, since it rotates constantly from the moment to the stop.
The generator drive is performed by belt transmission. On the crankshaft shaft And the generator rotor is installed pulleys, in the flow of which the belt is placed.
Types of generator belts
- The first type of drive belt is the usual wedge-shaped. Often this kind of belt is applied to the car, which were produced earlier. These belts are used on the car, where the drive from was produced only to the generator. The disadvantage of such a product is the high probability of slipping.
Wedge-shaped generator belt
One of the variants of a wedge-shaped belt, which came to replace the usual, is toothed. The toothed belt also has a wedge-shaped profile, but with inner He has a teeth. These teeth provide improved force transmission and a smaller degree of slippage. However, it is also used on cars, in which the drive from pulley is performed only on the generator.
Camotor Generator Belt
High flexibility allows it to be used to drive a generator, as well as other engine mounted elements - a hydraulic liner, a liquid pump and.
All kinds of belts are made according to one principle - the main material is a special rubber, the inside of which 2-4 layers of the reinforcing durable thread are placed.
Main problems with the generator belt
Since the generator drive belt is flexible, then the main problems with it are a break, strong wear, bundle and sedimentation.
The belt break rarely happens to be a significant effort of a rupture of reinforcing threads. It may occur only when the belt drives one of the elements is encins. For example, due to the destruction of the generator bearing, the rotor is possible with the subsequent impulse.
Strong wear occurs over time, because the belt surface when transmitting efforts rub about the surface of the pulleys. As a result, the belt profile decreases, it is increasingly slipping, the transfer force drops it and the generator ceases to produce the required energy.
Open car belt generator
The bundle is often obtained due to damage to pulleys. The violation of the geometry of the pulley leads to the fact that on the one side the belt is intensively wearing, the reinforced thread goes beyond the edges of the rubber material, as a result, the belt is gradually divided into components. The bundle may also occur due to poor-quality manufacturing material.
Car generator bundle
Sailing also occurs over time due to wear. Warming, the belt in diameter increases, its tension is weakening and slipping appears. Also, sediment can be caused by poor-quality manufacturing material. The ingress of fuel and lubricants on the belt surface often leads to a change in the physical parameters of rubber, which is why it can also be asked.
The main feature of the problem with the generator drive belt is the appearance of third-party noise, in particular the screens and shrill screech. Vgg usually appears due to belt slippage relative to pulley, which is often caused by strong wear or sizing.
The car, where the tension roller is used for the stretch, the appearance of the squeal can also indicate in addition to the belt wear also on strong wear of the roller bearing.
Long belt screech in winter time Indicates poor-quality manufacturing material. Such a belt at minus temperatures significantly loses its elasticity, which leads to intensive wear until it warms it. Such a belt will not serve for a long time.
Verification of state
On average, the belt resource is 50-60 thousand km. But its duration largely depends on the conditions of operation and quality of the product.
Determining the state and level of belt wear depends on constructive features car. But this definition is reduced to visual inspection belt.
Initially, the belt tension is checked. In normal condition, he should not like to press for a certain distance specified in technical documentation To cars.
Generator belt location scheme
You can eliminate the screech by an additional tension suspender. However, if you already stretch the belt of nowhere, it means he is strong.
If it is found that the belt is very worn ,. Before performing this operation, you need to purchase a new one. Moreover, you need to select on the model of the car, and also by the type of belt. The wedge belt cannot be installed in the place of the multicolum and vice versa.
Replacement on VAZ-2108
Consider how the replacement is made on different cars. To begin with, take the VAZ-2108 car, which uses a simple or toothed wedge belt.
This car is quite simple to replace the belt. You will need only the key to 17, as well as the mount.
Initially, you need to remove the waste belt, for which the fastening nut at thenime and nut weakens, clamping the generator on the tensioner. After the relaxation, the generator is fed to the engine, a highly light belt is removed from the pulleys. A new one is installed on its place, the generator is delayed from the engine, thereby tensioning the belt. Holding the tension in the mount, the nut on the tensioner is delayed. After tightening the fastening nut of the generator. After replacement, check is performed. If there is no heard on the engine of foreign sounds from the belt side, the replacement is performed successfully. If a screech appeared - re-tint is performed.
Replace on Toyota Camry
Next, consider how to replace the car Toyota Camry.. W. this car Used polyclinic belt. In this case, it is also used to drive the compressor and the liquid pump. A special tensioner is used to stretch.
If you replace on all the rules, you will need to remove the right wheel, lining and protect the engine crankcase to access the tensioner.
But some lovers do a replacement without removing the wheels. It is for the very replacement of the belt that you do not need to unscrew anything, because the tensioner is equipped with an appointment mechanism.
To remove the belt, you need a key to 19 per head placed on the tensioner, turn it clockwise. This action weakens the tension, after which the belt is removed from any pulley.
Before installing the new, you should look at the strap position of the belt between pulleys. To install it, it first throws on all the pulleys, after the tensioner is pressed and the belt will start onto it, after which the tensioner is released.
