How to tension a Chevy Niva alternator belt
Hello dear readers of the RtiIvaz.ru blog. Let's talk today about the generator drive belt, an auto repair kit that should always be kept in stock. A drive belt is an effectively low-cost means of transmitting rotation, which is created by the movement of an engine shaft, to engine auxiliaries such as a generator.
One rubber drive belt drives several units at once: generator, pump, timing belt, power steering pump, air conditioning compressor, radiator fan. When operating a car, it is necessary to regularly check the condition of the tires, as well as the tension. To avoid engine breakdowns, you need to replace rubber repair kits in accordance with the machine's maintenance instructions. Video:
Automotive rubber drive belts, simply put, come in several types - wide, narrow, toothed, smooth, each car has its own size and shape. To reduce wear on the side parts and provide integrity, wrapped ones are used; cotton and nylon are used as the outer covering. Toothed belts apply force through transverse teeth and a drive mechanism, maintaining the specified shaft alignment. When operating a car, it is not recommended to lubricate them with oil; they actually do not stretch or vibrate, and last longer than smooth ones.
With the improvement of technology, various types of repair kits began to be produced. For injection cars, multi-strand wide ones are produced, which consist of several drive belts welded together. Due to this design, the load is evenly distributed between the streams; as a result, repair kits for rubber products have an increased service life of the vehicle. It can simultaneously rotate the pulley of the generator, power steering, and air conditioning compressor.
The V-belt is designed to accurately match the rotation speeds of the unit pulleys. Double-sided V-belts have good driving properties. To transmit high powers, poly-V rubber drives are used, which have teeth at the bottom and are flat at the top.
Before buying Lada car belts or other auto repair kits for rubber products, you need to look at such parameters as profile, width, pitch, number of teeth, good quality, width and length dimensions must correspond to the brand of the mechanism being used.

How to tension the alternator belt on a VAZ 2106 yourself?
For the generator to operate efficiently, it is important that the belt is sufficiently tensioned. The size of the VAZ 2106 alternator belt must correspond to the recommendations specified in the operating manual. In addition to following the recommended size, you should regularly check the tension. The article provides detailed instructions on how to correctly change and tension the VAZ 2106 alternator belt.
Types of alternator belts

Two types of belts are used to drive the generator.
The first type of drive belt is a regular V-belt. Often this type of belt is used on cars that were produced earlier. These belts are used on cars where the drive from the crankshaft pulley was carried out only by the generator. The disadvantage of this product is the high probability of slipping.
Alternator V-belt
One of the variants of the V-belt, which replaced the usual one, is the toothed one. The timing belt also has a V-shaped profile, but it has teeth on the inside. These teeth provide improved power transmission and less slippage. However, it is also used on cars in which the drive from the crankshaft pulley is carried out only by the generator.
Tooth type generator belt
The second type of drive belt, which is increasingly used on cars, is a poly-V belt, also known as a multi-ribbed belt. This type of belt is much wider than a V-belt, but thinner, which provides it with greater flexibility. Several grooves were made on the inside, the profile resembling a wedge, but small in size. Because of these grooves, this belt received the popular name - multi-groove.
Alternator serpentine belt
High flexibility allows it to be used to drive a generator, as well as other attached engine elements - hydraulic booster, liquid pump and compressor.
All types of belts are made according to the same principle - the main material is special rubber, inside which 2-4 layers of strong reinforcing thread are placed.
What size should the alternator belt be?
The belt serves as the link between the crankshaft and the generator shaft, which provides electricity for the vehicle. If it breaks, the car will stop. The product is a rubber ring, the condition of which should be constantly monitored and changed as necessary.
Belts are evaluated according to the following parameters:
- profile;
- length;
- width;
- thickness.
There are three types:
- gear,
- polycline;
- wedge
Types of rubber consumables
The original for the VAZ 2106 has a size of 10x944 with a wedge angle of 39 degrees. It is easy to install and adjust. You should buy original products. Poor quality ones may not meet the required dimensions and may stretch during operation, which will affect the power of the power unit. These products are consumables that are recommended to be changed every 15 thousand or when defects are detected.
Generator faults
Connection diagram for the VAZ 2106 generator
Unfortunately, mechanisms have not yet been invented that would not fail under the influence of time and constant loads. The VAZ 2107 generator is designed for many years of operation, but in some cases this is hampered by minor breakdowns and malfunctions of its components.
You can identify problems with the generator without the help of service station specialists: you just need to carefully monitor all the changes that occur with the car while driving.
The charging indicator light on the instrument panel came on
In the interior of the VAZ 2107, there is a terminal for several signaling devices on the dashboard. One of them is the battery charging indicator light. If it suddenly lights up red, it means there is not enough charge in the battery or there is a problem with the generator. But the alarm does not always indicate a problem with the generator itself; most often the lamp goes off for other reasons:
- slipping of the generator belt drive - you will need to stop the machine and adjust the degree of belt tension;
- there is damage in the warning lamp relay, so it does not work correctly - it is recommended to “ring” the relay in the mounting block and, if necessary, replace it;
- breakage of contacts in the excitation winding is a more serious damage that requires removing the generator from the car, disassembling it and searching for a break;
- severe wear of the brushes in the brush holder - they will need to be replaced, which is quite simple;
- short circuit in the rectifier (most likely, one of the silicon diodes has burned out) - it is recommended to disassemble the generator, test the diodes and replace the failed element.
The driver will immediately notice the signal, as the lamp begins to glow bright red on the instrument panel
The battery is not charging
VAZ 2107 drivers often encounter this problem: the generator seems to be working properly, but there is no power to the battery. The problem may lie in the following malfunctions:
- the alternator belt has stretched - you need to check the degree of its tension or replace it with a new one;
- loosening the fastening of the wire tips - just tighten all the fastening connections and thoroughly clean the contacts and connectors;
- malfunction of the battery itself;
- Damage in the wiring - it is recommended to ring all the wires between the battery and the generator and replace the damaged areas.
If there is no charging, the problem may lie in both the generator and the battery.
The battery is boiling over
Battery boiling over is a sign that the battery does not have long life left. After this, the battery will not be able to function fully, so it will have to be replaced soon. However, so that the replacement does not lead to the same sad consequences, it is necessary to find the cause of the boiling, which may be:
- contamination of the contact between the ground and the housing of the generator regulator - cleaning of the contact is necessary;
- damage to the voltage regulator board itself - replacement of the board is recommended;
- defective battery - if the battery began to boil away immediately after replacement.
It is better not to use the battery after boiling, as its resource is very limited.
When driving there is noise and grinding noise from the generator
The generator has a rotating rotor, so it must make noise during operation. However, if these sounds become increasingly loud and unnatural, you should understand the cause of their occurrence:
- loosening the nut on the pulley - you need to tighten the nut and check the degree of belt tension;
- deterioration of the bearings - in this case, the driver may hear a loud grinding noise and even a howl while driving; it will be necessary to press out the old bearings from the shaft and install new ones;
- short circuit in the winding - the entire stator needs to be replaced;
- creaking brushes - it is recommended to clean the brushes from adhering dirt.
Optimal alternator belt length
A car engine alternator is unable to perform its intended tasks properly if the wrong length belt is installed on it. If it is too long initially, or its length increases during operation, this can lead to a number of very unpleasant consequences. Naturally, no one wants to deal with engine repairs; for this reason, it is very important to immediately install a belt of the correct length or adjust its tension in a timely manner. You can find out exactly what size alternator belt you need from your car's operating instructions. We will tell you how to tighten it in case of sagging in the article below.
Correct alternator belt length
The role of the alternator belt in the functioning of the car as a whole is quite high. Thanks to it, torque is transmitted from the crankshaft to the generator shaft, resulting in the generation of electrical energy to power the most important components of the car. In this regard, the generator belt must always be in good condition and have dimensions that fully comply with the requirements of the device itself. In particular, at the moment when the alternator belt breaks, the car simply stalls and can no longer continue to move.
The belt itself is a rubber product that is a vicious circle. Due to the importance of this element, its condition must be constantly monitored by adjusting the tension force, as well as replacement if such an operation becomes necessary. When choosing a belt for your car, you can evaluate the reliability of a belt using several parameters:
In addition, today there are three types of belts that are installed on generators:
You can find out which belt, according to all the above parameters, should be installed on your car from its personal instructions. If for some reason it was lost, today you can easily go to the manufacturer’s official website and read similar instructions on the Internet. For example, if we are talking about a Russian-made car VAZ-2106, then for this model it is necessary to select belts with the following parameters:
— wedge angle — 39º.
In this case, it will be as easy as possible for you to install and adjust the belt, since it will perfectly fit the unit for which it is intended. At the same time, it is very important to buy original products that are of the highest quality and reliability. The fact is that the length of the generator belt is one of the main indicators on which the overall performance of the device depends. And even if at the time of purchase you choose a belt of the required length, during operation a low-quality product can stretch significantly, thereby reducing the power of the generator.
At the same time, do not forget that the alternator belt is a consumable item. Therefore, it is not worth tightening it up too often and trying to prolong life with various additional means. According to the instructions of most manufacturers, the alternator belt should be replaced after every 15,000 kilometers. But if its length exceeds the permissible norm, it should be done more often.
Long alternator belt: what consequences can this lead to?
If the generator is not functioning properly, you can tell by a characteristic sound. In particular, if a too long belt is installed on it, or this element simply stretches and begins to sag from intensive use, then when you turn on a large number of electrical appliances in the car, you will hear a very unpleasant whistle. It occurs due to weak tension and the fact that the generator belt can simply slip on the pulleys.
There is no doubt that belt stretching will also affect the operation of the electrical appliances themselves:
1. Variable changes may occur in the voltage of the vehicle’s electrical circuit.
2. Instruments and headlights provide very dim light, which is not even enough to fully illuminate the roadway.
3. A red signal may light up on the instrument panel, which will notify you that there is a problem with the battery.
This phenomenon should not be neglected. As a result of belt stretching and improper functioning of the generator, the car battery may malfunction. Therefore, if you purchased a belt that is too long for installation on the generator and do not see the need to tension it, you should think about the real danger that you can provoke with such a decision. But at the same time, you should not overdo it with the tension force. If the product is over-tensioned, it may damage the generator bearings.
How to tension the alternator belt on your own?
We don’t think it would be superfluous to once again emphasize that the tension force of the alternator belt should be optimal. If you press it with a force of several kilograms, its maximum deflection should be only a few millimeters. The maximum permissible value is 1 cm, and then only for a certain type of generator, designated 9402 or 3701.
It is not at all difficult to tension the alternator belt yourself if it is sagging; the main thing is to know how to do it correctly. You should immediately prepare the set of tools necessary for the work: two open-end wrenches for 17 and 19. Moreover, you don’t even have to spend too much time on this procedure; on average, the work will take about half an hour. It is only worth noting that for each type of generator these works will be carried out in their own way, so, based on our instructions, still be attentive to the features of the generator installed on your car. The process of tensioning the generator belt can be carried out in two ways. We will tell you about each of them.
Features of tensioning the generator belt using an adjustment bar
This tensioning method is not suitable for all cars; it is best to apply it to VAZ classics. Using an adjustment bar greatly simplifies the work process, so this method is best suited for carrying out this procedure at home.
Before you start tensioning the belt, you first need to attach the generator to the car engine crankcase, which is recommended to be done using a long bolt. At the same time, the generator should still move freely up and down. After this, find an arched bar at the top of the device, which has a slot in it and is secured with a nut, which also secures the correct position of the generator itself. Next, we directly tension the belt by performing the following steps:
1. Unscrew the fastening nut, which is located on the generator plate.
2. Using a mounting spatula or other available tool, carefully press the generator away from the engine.
3. Tighten the nut back.
4. Check how this affected the belt tension force. If it still sags, the procedure must be repeated.
We use an adjusting bolt to tighten the generator belt.
A more modern and universal way to tension an alternator belt that is too long is to use an adjusting bolt. In order to achieve the desired result, you will need to complete the following list of works:
1. Loosen the upper and lower nuts that secure the generator.
2. Turn the adjusting bolt clockwise while gradually and carefully moving the generator away from the block. It will be very good if you have a partner working with you, who will assess the degree of belt tension during this procedure.
3. Tighten the generator mounting nuts until they stop.
To complete the procedure for tensioning the generator belt (regardless of which method you used for this), you need to use a special wrench to perform 2-3 revolutions of the crankshaft. After this, check the belt tension again. It is worth checking the effectiveness of the work performed again after driving the car. If such a procedure does not help restore the belt to its functionality, it should be replaced with a new one, and immediately select the required length.
It is necessary to draw your attention to the fact that if there is a need to tension a belt that has become stretched during operation, its further use should not be too long. This is due to the fact that after stretching, the belt loses a number of its properties and can no longer fully perform the task assigned to it. So, when tensioning such a belt, you should immediately be prepared to replace it soon.
The generator belt is designed to ensure rotation of the rotor, as a result of which this unit is able to generate the energy necessary to power the on-board network. Therefore, the strap must always be in working order, otherwise the driver simply will not be able to fully use the car. We will talk about the types and typical malfunctions of the strap in this article.
Regardless of the length of the generator belt, two types of belts can be used to ensure the operation of the device drive:
- Wedge-shaped. Traditional RG, used mainly in cars produced earlier. Operation of this type is relevant in vehicles in which the drive from the crankshaft is carried out only by the device itself. A significant disadvantage of such a RG is that during its operation there is a high probability of slipping. A more advanced version of the wedge version is the serrated one, characterized by a wedge-shaped profile as well as teeth on the inside.
Poly-wedge. Another type of RG, which has recently been used much more often, is poly-wedge or multi-stream (multi-stream). Regardless of the number of the alternator belt, the width of the alternator belt will be larger, but at the same time thinner. This, in turn, allows for greater flexibility. Such a RG was named multi-stream due to the fact that there are several rows of furrows on its inner side. Due to the fact that this type of RG is more flexible, it is usually used not only to drive a generator, but also other components - power steering, compressor, air conditioner, etc.
Regardless of what type the generator drive belt is, they are all manufactured according to the same principle. It is based on specialized rubber. Also, the design of such RGs includes several layers of strong reinforcing thread.
Repair of under-hood power plant
Removing the generator is a simple procedure. However, to perform it you will have to crawl under the car. In addition, it is better to remove the battery in advance, as it will interfere with unscrewing the nut securing the device to the adjustment bar.
- We roll the car into a hole or lift the right front part of the car with a jack and place bricks under it. Don't forget to put the car in gear or put the handbrake on.
- We remove the crankcase protection if it interferes.
- Slightly unscrew the nut of the lower mounting of the generator.
- We get out from under the car and loosen the nut on top that secures the unit to the adjustment bar.
- We push the generator towards the engine and remove the drive belt, first from the pump pulley, and then from the generator and crankshaft pulleys.
- We finally unscrew the nut securing the unit to the adjusting bar and remove it together with the washer.
- We climb under the bottom again, unscrew the cap of contact “30”, then disconnect the remaining wires and remember where to plug them in later. If the memory is bad, we mark everything with a marker.
- We finally unscrew the nut securing the generator from below, remove the bolt with one hand, and support the device with the other so that it does not fall.
- We pull the generator down, after tilting it.
Repairing a VAZ generator is not a very simple matter. To overhaul the unit, you need to have many special tools for disassembly and diagnostics. Therefore, it is better to entrust such an operation to specialists who have all the necessary equipment.
Without special knowledge and pullers, only replacing the generator brushes is possible. To perform this operation, you need to find contact “67” on the back cover of the unit. Directly below this contact there is a brush holder secured with just one screw, which must be unscrewed. Now we pull out the brush holder, check the condition of the brushes and the distance at which they protrude from the device. If this indicator is less than 12 mm, the brushes must be replaced.
Hello, in this article you will learn how to replace the generator on a VAZ 2101, 2102, 2103, 2104, 2105, 2106, 2107. The generator is needed to generate charging for the battery and provide voltage to all electrically dependent parts of the car. The generator does not have a specific service life; it can last 100,000 km, but it can fail even after 10,000 km. The first sign of a generator failure is a constantly draining battery (in rare cases, the cause may be in the battery itself). To check the operation of the generator, you need to use a tester to check the voltage at the battery terminals with the car running. The voltage values should be between 13.8 and 14.5 volts; if it is lower, then the generator definitely needs to be repaired or replaced with a new one. Most often, the generator can be repaired; usually the diode bridge or voltage regulator fails; replacing these parts will cost much less than buying a new generator, since its average cost in the automotive market is about 5,500 rubles. To remove the generator you will need: keys or sockets for 10, 13, 17 and 19. First of all, we remove the terminal from the battery. After this, unscrew the nut that secures the generator to the adjusting bar (depending on the type of generator, you will need a 13 or 17 socket here)
Next, move the generator so as to loosen the tension on the generator belt and remove the generator belt. Then remove the terminal from the generator
The next step is to unscrew the nut securing the positive wire using a 10mm wrench and remove the terminal
Now use a 19 mm socket to unscrew the generator mounting bolt and remove it by removing the bolt from the bracket
Installation of the generator is carried out in reverse order.
Typically, the VAZ 2106 generator must be replaced only in the most exceptional cases, and in case of most malfunctions it is simply repaired. But if this device on your car has completely failed and cannot be repaired, then it is necessary to replace it. To make replacing the VAZ 2106 generator as simple as possible, below is a list of necessary tools that will help make this operation easier:
- Keys for 17 and 19
- Heads for 10, 17 and 19
- Ratchet handles and knobs
- Extension with universal joint
How to replace the alternator belt
In order to perform this procedure, it is necessary to unscrew the upper bolt of the generator, which acts as a tensioner.
There is no need to unscrew it completely, just make a couple of turns of the nut to loosen the tension. Next, you need to crawl under the car and loosen the fastening nut from the bottom; you can first spray it with penetrating lubricant:
Once the lower fastening is loosened, you can proceed to further actions. Now we take the top nut of the generator with our hand and try to move it to the right side, thereby loosening the tension to a minimum.
Now take a look at the photo below. It is in this position of the upper mount of the generator relative to the tensioner that the belt can be quite easily removed from the pulleys:
We make sure that the belt is sufficiently loosened and remove it from the pump pulley (water pump) of the VAZ 2106:
Now it can be easily removed from the remaining pulleys and after that you can immediately install a new one in the reverse order.

In what situations is replacement necessary?
Element wear is characterized by such manifestations as cracks or tears in the blade, worn teeth and uneven edges
If you ignore such a deplorable state of a very important element, it will come back to haunt you with overheating and boiling of the engine, independent operation of the battery, which will lead to its rapid discharge
If the belt is severely worn, it also shows signs of noise to the owner - it begins to whistle, especially at low speeds. Another reason for a whistling belt may be moisture getting on its surface, which occurs due to worn-out pipes of the cooling system - antifreeze begins to leak.
Some belts - oak - whistle when the car is started in frosty weather, and after warming up the sound disappears. A weak tension is expressed by a whistle, but in this case it is enough to simply tighten it.
Replacing front and rear seat belts on a VAZ 2106
If you are involved in an accident, then after it you will not only have to carry out body repairs, but also change the deployed airbags along with the belts, or only the latter, since your car may not have airbags. But even if you have never been in an accident in your entire driving experience, seat belts (SB) can become unusable, simply wearing out and losing strength over many years of service, after which they need to be replaced with new ones. Below you will learn how to do this on a VAZ-2106 car.
Content:
You will need a minimum of tools: a flat-head screwdriver and a 17mm wrench or socket wrench. Well, a new belt and its lock, of course.
Replacing front seat belts on a VAZ 2106
The diagram shows the location of the belt: number 1 is the reel, number 2 is the belt itself, 3 is the latch, and 4 is the loop.
1) Take a screwdriver and use it to carefully pry the cover on the hinge mounting bolt.
2) Remove the trim, being careful not to damage its clips.
3) Take the key and unscrew the bolt that secures the RB hinge.
4) After removing the hinge, try to put it somewhere in a visible place so that the small parts associated with it do not get lost.
5) Arm yourself with a screwdriver again and remove the cover, but this time on the coil.
6) Unscrew its mounting bolt, being careful not to lose the washer and spacer.
7) Remove the coil.
Take the new belt and install it in place of the old one.
After installation, it is important to check the smooth movement of the belt so that it can be pulled out and retracted without hindrance. If there are problems with this, you need to adjust the position of the reel so that the slot in it is horizontal in relation to the belt, and not at an angle.
You also need to check whether the reel is defective: normally, when jerking, the belt should not move, but when pulling smoothly, on the contrary, it should. If the coil does not work normally, it should be exchanged for another one at the store.
Usually, along with the belt, its lock, located between the front seats, also changes.
To replace it you should:
- Remove the cover on the mounting bolt.
- Unscrew the bolt, removing the sleeve and washer, after which the lock will be removed.
- Install a new lock.
How to change rear belts and their locks on a VAZ 2106
Rear belts usually last longer than front ones, but they don’t last forever. The tools are the same, but to replace it you will first have to remove the back of the rear sofa. Further:
1) Use a screwdriver to pry up the cover and then remove it.
2) Unscrew the mounting bolt located at the bottom.
3) Repeat step 1 for the top fastening, exactly like step 3.
6) Then unscrew the bolt securing the hinge, and then remove it with its associated small parts.
7) Now it's the turn of the coil bolt.
Next you need to pry up and remove the RB guide.
9) Pass the belt assembly with guide and loop through the slot in the rear pillar trim panel.
10) Dismantle it, after which you can install a new RB.
Replacing locks is done as follows:
- The back row of the back row is removed (if you have not done this earlier).
- The mounting bolts are unscrewed
- After which the locks can be easily removed and replaced with new ones.
In conclusion, it should be noted that if you also want to change all the bolts securing the hinges, locks and coils, then you should buy new ones only at a car dealership, since these are specialized parts that can withstand high loads. It is strictly forbidden to install ordinary bolts, since in the event of an accident they will be cut off, which will lead to a sad outcome.
Reasons for the break
- 1. Exhausted resource. The belt needs to be changed at 50-60 thousand kilometers, but many do not do this;
- 2. Defective product. The manufacturer may produce low-quality goods;
- 3. Failed tension rollers, shafts and pulleys;
- 4. Incorrectly selected belt tension level.
Signs of wear:
- 1. Lack of teeth. If there are no teeth, the product cannot engage on rollers, pulleys and shafts;
- 2. External modifications. If cracks, chips, stretching and other defects are noticed, urgent replacement is needed.
If you hear a whistle from the engine compartment when the radio, fog lights, regular headlights, etc. are on, then most likely it’s time to change the belt. Often, the whistling is eliminated if you tighten it, or vice versa, loosen the product a little. If the generator malfunctions, the “Check engine” indicator or, literally translated, “engine malfunction”, lights up on the instrument panel of the VAZ 2107.
If the belt breaks, it will not immediately become clear that it is broken, since the car’s electronics will be powered by battery energy. To prevent this, you need to monitor the condition of the product and, if necessary, try it on.
Adjusting belt tension VAZ-2106
The degree of tension of the belt should be such that when pressed with a force of 10.2 kgf between the pump and generator pulleys, it bends no more than 1-1.5 cm. Of course, experienced motorists can determine the degree of tension of the VAZ-2106 belt and by eye, without a device to measure the force.
To tension the belt on a VAZ-2106
it is necessary to loosen the nut securing the generator to the adjustment bar.
It is located at the top of the generator. You will also need to loosen the nut of the generator hinge pin. It is located at the bottom of the back part. Next, the generator is moved in the opposite direction from the motor, after which the above-described nuts are tightened. The VAZ-2106 belt

Tension with adjuster bar
Securing the generator using a strip
This method is used for older cars (for example, “classic” VAZs). It is based on the fact that the generator is attached to the engine using a special arc-shaped strip, as well as a bolt and nut. By loosening the fastening, you can move the bar with the generator relative to the engine to the required distance, thereby adjusting the tension level.
Actions are performed according to the following algorithm:
- unscrew the fastening nut on the arc-shaped bar;
- Using a pry bar, we adjust the position (move) of the generator relative to the engine;
- tighten the nut, fixing the new position of the generator.

This method is more progressive and is used in most modern machines. It is based on the use of a special adjusting bolt, by turning which you can adjust the position of the generator relative to the engine. The algorithm of actions in this case will be as follows:
- loosen the generator, its upper and lower fastenings;
- Using the adjusting bolt, we change the position of the generator;
- fix and tighten the generator mount.
The belt tension level in this case can be determined during the adjustment process.
Adjusting roller and key for it
Work on tensioning the alternator belt on a Lada Priora car is carried out using a special tension roller, which is part of the structure. To work, you will need a 17 mm wrench to unscrew and lock the mentioned roller again, as well as a special key to turn the adjusting roller (it is a structure of two rods with a diameter of 4 mm, welded to the base, the distance between the rods is 18 mm).
Voltage regulation process
To adjust with a 17 key, you need to slightly unscrew the fixing bolt that holds the adjusting roller, then use a special key to turn the roller a little in order to increase (most often) or decrease the belt tension. After this, use the 17 key to fix the adjusting roller again. The procedure is simple and even an inexperienced car owner can handle it.
It is only important to choose the right force
After you have done the tensioning, you need to perform a check. To do this, start the engine and turn on the maximum consumers of electricity - high beams, heated rear window, air conditioning. If they work properly and the belt does not whistle, it means you have tensioned correctly.
Alternator belt tension on Priora
Another method for tightening the alternator belt on a Priora
You will find detailed information about the process of replacing the alternator belt on a Lada Priora in the corresponding material.
On different modifications of Ford Focus cars, one of two systems for adjusting belt tension is used - using an automatic or using a mechanical roller. In the first case, operation is much simpler for the owner, since the belt is tensioned using built-in springs. Therefore, the driver only needs to periodically replace the belt (either on his own or at a service station).
In the case of a mechanical roller, tension must be done manually using bench tools - a pry bar and wrenches. The design of the roller mechanism may also differ. However, the essence of the procedure comes down to the fact that it is necessary to slightly loosen the fastening of the roller, tighten it and fix it again.
Note! Buy original belts, as often non-original ones are slightly larger, which is why it will whistle and get hot after installation. We invite you to familiarize yourself with the material, which presents the procedure for replacing the alternator belt on a Ford Focus 2 car - article

We change it with our own hands
It is more convenient to perform the replacement on an overpass or inspection ditch. In extreme cases, you can use a jack. Before work, you should prepare a set of tools and new consumables.
The drive belt is located in the front of the engine compartment and is tensioned over the alternator, crankshaft and cooling system pump pulleys. The strength of its tension can be checked by deflection in two places:
- between the crankshaft pulley and the pump, the deflection should be within 1.2 - 1.7 cm;
- between the pump and generator pulley – 1 -1.5 cm.
If there is a discrepancy, adjustment must be made.
Stages of work
The tensioning procedure is one of the replacement stages, which consists of the following steps:
- First you need to unscrew the upper mounting bolt of the generator, which acts as a tensioner. There is no need to unscrew it completely; a couple of turns are enough to loosen the strap.
- Then you need to move under the car and loosen the lower nut securing the unit.
- Next, holding the upper fastening nut, you need to move the device towards the cylinders until the minimum tension is achieved.
Loosen the tension nut
Thus, replacing consumables on a VAZ 2106 is not difficult and can be done with your own hands. These skills will make it possible to avoid surprises on the road, you just need to have a consumable in the trunk.
The device of the VAZ 2107 generator
Structurally, the generator on the “seven” has the shape of a cylinder. The cast body contains many small parts, each of which performs its own functions. The main elements of the G-221A are the rotor, stator and covers, which are cast only from a special aluminum alloy.
Rotor
The G-221A rotor consists of a shaft with a corrugated surface, onto which a steel sleeve and poles are pressed. The bushing and beak-shaped poles together form the so-called core of the electromagnet. The core produces an electromagnetic field during the rotation of the rotor shaft.
The excitation winding is also located inside the rotor. It is placed between the poles.
The moving element of the rotor - the grooved shaft - rotates thanks to two ball bearings. The rear bearing is mounted directly on the shaft, and the front bearing is fixed on the generator cover.
The rotor is pressed into the generator winding and does not separate from it during disassembly
Stator
The stator is assembled from special plates 1 mm thick. The plates are made of electrical steel. It is in the stator slots that the three-phase winding is located. The winding coils (there are six in total) are made of copper wire. Strictly speaking, the electromagnetic field coming from the rotor core is converted by the coils into pure electricity.
Wire breaks or carbon deposits on its surface can affect current generation
Rectifier
The generator in the described configuration produces only alternating current, which is clearly not enough for the smooth operation of the car. Therefore, in the G-221A case there is a rectifier (or diode bridge), the main task of which is to convert alternating current into direct current.
The diode bridge has the shape of a horseshoe (for which it received the corresponding nickname among car enthusiasts) and is assembled from six silicon diodes. On the plate, three diodes have a positive charge and three have a negative charge. A contact bolt is installed in the center of the rectifier.
Structurally, the rectifier really looks like a horse's horseshoe
Voltage regulator
The voltage regulator on the VAZ 2107 is made together with a brush holder. The device is a non-separable unit and is fixed to the back cover of the generator. The regulator is designed to maintain the rated voltage in the network in any operating mode of the engine.
The regulator's electrical circuit controls the voltage in the device
Pulley
The pulley is not always considered an integral part of the generator, since it is mounted separately on an already assembled housing. The main task of a pulley is to transmit mechanical energy. As part of the generator, it is connected by a belt drive to the crankshaft and pump pulleys. Therefore, all three devices work in an inextricable connection with each other.
The pulley is mounted on the rotor shaft and connected by a belt drive to the corresponding parts of the pump and crankshaft

Changing the belt on a VAZ 2101-VAZ 2107
Removal
It is necessary to have access to the top and bottom of the car. If you have a crankcase protection installed at the bottom, then you will have to remove it accordingly; read the details in the article: “Replacing the crankcase protection on a VAZ.”
Note! Removing the battery will make the belt easier to access. The process is described in the article: “Replacing the battery in cars.”
Evaluate the appearance of the belt. If the condition is good, check the tension and tighten it if necessary. It’s easy to check: press the belt with your fingers with a force of 10 kg anywhere. Either in place “A” the distance by which the belt should bend will be 10-15 mm, or in place “B” 12-17 mm (see picture).
Note! It is more convenient to press and check the deflection at point “A”. Any deviation from the norm requires tightening the belt. Remember, do not remove the belt from the pulleys unless you intend to replace them!
Move to the lower part of the car and unscrew the lower nut of the generator one turn (see small photo), get out from under the car and go to the engine compartment. Loosen the nut of the upper fastening of the generator one or two turns (red arrow in the photo), an extension with a universal joint and a union head will help you (tools are indicated by a blue arrow). Loosen through the battery installation bar.
Note! The top nut securing the generator to the bar is screwed differently for everyone, so when you feel that the nut goes on easily (be careful not to unscrew it completely), then stop unscrewing immediately!
Let's move on to changing the belt. Use your hands to move the alternator towards the engine and remove the belt. If you just need to adjust, then insert a mounting blade between the engine and between the generator itself (see photo below), and, using the blade as a lever, move the generator away from the engine. Holding it in this position with a spatula, tighten the upper nut securing the generator to the bar and the lower one too. Release the paddle and remove it, check the belt tension and, if necessary, perform the operation again (if the tension is not within the normal range).
Note! Having unscrewed both nuts, first remove the belt from the upper pulley, and only then from the steel ones. The topmost one is the cooling pump pulley. On fuel-injected cars, in addition, remove the crankshaft position sensor, otherwise it will not allow you to remove the belt, and you will break the crankshaft sensor. For details, read the article: “Replacing the crankshaft position sensor.”
Installation
First, install the belt on the crankshaft pulley. In the image above, look at the pulley indicated by number 3, the generator pulley by number 2 and the pump pulley by number 1. Move the generator completely towards the engine, if it is moved, but the belt still does not install, then carefully turn the pump pulley (upper) by hand, or at the extreme In this case, ask an assistant to use a crooked starter to turn the pulley a little, while you put the belt on the upper pulley of the pump.

How to tighten or loosen the alternator belt on a VAZ 2106
Tensioning is quite simple. It is necessary to follow some steps that were described above, namely: loosen the upper and lower nuts securing the generator. Then we make adjustments: either tighten or loosen the belt. Again, this is all done using the tensioner top plate. If you need to tighten it more, then you need to move the generator itself to the left, and if, on the contrary, you loosen it, then accordingly - to the right.
After completing this procedure, tighten both nuts to the required torque and check how correctly everything was done. We start the engine and turn on all electrical appliances:

Belt tension
To adjust the belt tension you will need a mounting spatula and wrenches “19” and “17”. It is best to install the car on a viewing hole or lifts. This position of the car will greatly facilitate your work process. The essence of the adjustment is to move the generator relative to the engine.
- First of all, remove the engine mudguard.
- Then unscrew the generator mounting nut one turn. Then unscrew the nut securing the generator to the adjusting bar by one turn.
- Begin to gradually move the generator in relation to the engine, thereby achieving optimal belt tension. After this, tighten the generator mounting nuts.
Belt replacement
If you decide to change the belt, then follow the same procedure, only the generator mounting nuts should be loosened a little more. This way you can easily move the alternator away to remove the belt from the pulley. The new belt must be placed first on the crankshaft pulley, then on the pump and generator.
