Tighten the alternator belt VAZ 2110 8 valves

Performing tension

If there is no wear on the V-belt drive, but there is a whistle, first of all, check the tension level. We will not use complex terminology, but will simply advise you to press with some force on the belt in the middle.

If the tension is done correctly, then the belt will bend no more than 8 millimeters. If the deflection is greater, then the element will have to be tensioned, and if it practically does not deflect, the tension will have to be loosened. The problem is not the whistling. Due to weak tension, the battery does not charge effectively, and the drive itself begins to wear out faster. Excessive tension can lead to damage to the alternator bearings and stretching of the belt.

Correct tension of the VAZ 2110 generator belt is performed as follows:

Loosen the generator from the bottom and top. A nut is used for this;
Turn the adjusting bolt and adjust the belt;
If you want to increase the tension, the bolt is turned to the right. Thus, you move the generator away from the cylinder block;
To loosen the tension, move in the opposite direction - to the left;
Use a wrench to grab the fastening bolt and turn the crankshaft a couple of turns, then check the tension;
If all is well, the tension is correct, the nut can be tightened back.

Video instructions for tensioning or loosening the alternator belt on a VAZ 2110-2112

To show everything clearly and clarify the picture, I decided to record a short video that contains instructions in an accessible form:

First, make a few turns and try to tighten the belt, perhaps this will be enough to prevent it from squealing. And it's quite easy to check. Start the car with the lights and other electrical devices turned on as much as possible (high beams, heated rear window, heater, etc.) If at this time the whistle is not heard, then the belt is properly tensioned.

But you shouldn’t forget about the constriction, and this shouldn’t be allowed. If you hear that a strange hum suddenly begins to appear from the side of the generator, most likely due to a tightened belt, the bearing is humming, then you urgently need to loosen the tension a little until the sound goes away.

Replacement

We have already figured out how to tighten the alternator belt. But such measures are not always relevant. If the element is cracked, overstretched and no longer tensioned, then there is nothing left to do but replace it with a new one.

In fact, replacement cannot be called a complex procedure. Follow the instructions and everything will work out.

Slightly loosen the bolt nut from the lower mounting of the car generator, as well as the tension nut.
Loosen the tension of your belt further. You already know how to do this from the previous section, where we talked about tensioning the alternator belt.
Move the generator towards the power unit, which will allow you to remove the belt from the crankshaft and generator pulleys.
The next step is to install a new element. To do this, you will need a high-quality belt purchased from a trusted store. What exactly this part will be and what size it will be is not difficult to determine. But quality comes first.
First, the belt is put on the crankshaft pulley.
Now it goes to the generator pulley.
At the last stage, you have to repeat the tension adjustment procedure. You already know very well how this procedure is carried out, so there should be no problems.

How to change the belt yourself

If you have ever encountered the need to replace a belt on a 16-cl or 8-cl engine, then this procedure will not take much time. If you are encountering this for the first time and have never heard of a generator before, we recommend that you seek help from specialists. Don't forget that one wrong action can lead to irreversible consequences. Therefore, these instructions will help everyone who decides to replace the belt for the first time.

Required Tools

Of course, any repair work begins with the preparation of the necessary tools. To replace the strap on an 8- or 16-cl. Lada Kalina engine, prepare:

open-end wrench size “19”;
socket wrench set to “8”;
wrench to “13”;
new alternator belt.

Open-end wrench on "19"

Socket wrench "8"

Wrench "13"

New generator element

Stages of work

If you have prepared everything that may be required in the process, then you can begin the replacement work. So let's get started:

Turn off the engine and open the hood of the Lada Kalina.
The alternator belt can be found on the left side of the engine compartment. If you don’t know where it is, then start the engine and look in the engine compartment. The strap will rotate on rollers and you will see it.
Having found the installation location of the element, take a wrench and loosen the screw that secures the adjusting rod. Immediately try to touch the belt to see how tight it is. This is necessary so that you understand how to set the tensioner after installing the element.
When the nut is loosened, take an “8” spanner and tighten the adjusting rod. When you start turning it clockwise, the tension on the generator belt on the rollers will be loosened. Turn the rod almost all the way.
This will loosen the belt tensioner on the rollers. If the tensioner is already loose, you can unscrew the lower fastening of the device. To do this, use the key at “13”.
It is necessary to move the adjusting rod upward. When the rod is pulled back, the strap can be removed, but first remove it from the shaft of the device.
Once the belt portion is removed from the pulley assembly, remove it completely from the crankshaft.
Pull out the element and visually inspect it. If the strap is cracked, you will see other signs of deformation, for example, the shape has changed, then it must be replaced. Install the new component in place of the old one, assembling everything in reverse order.
When the installation of the element is completed, it is necessary to check the tension on the rollers. The tension must be adjusted using the appropriate rod. The element should not be too loose as it will regularly come off while riding. But it shouldn’t be too tense either.
Start the engine and warm up the car to 50 degrees. Then turn off the engine and check again how tightly the element is tensioned. If it's loose, tighten it.

1. Stop the engine and loosen the adjusting rod nut

2. Tighten the adjusting rod so that you can loosen the belt.

3. Move the rod up and remove the strap, first from the generator pulley

4. Remove the element from the crankshaft pulley

How to properly replace and tension the VAZ 2110 alternator belt (8 valves)?

06/05/2018 Quite often a whistle is heard in the V-belt connection, indicating the need to tighten or replace the belt. Let's focus on tightening and replacing the belt on the VAZ 2110 model.

Quite often a whistle is heard in the V-belt connection, indicating the need to tighten or replace the belt. Let's focus on tightening and replacing the belt on the VAZ 2110 model.

The appearance of a characteristic sound is due to the following reasons:

poor belt tension. Typically, a whistling-like sound occurs at night. This is explained by the increased operation of the generator due to the need to provide the vehicle with lighting;
moisture. Quite a rare occurrence. In this case, the car owner needs to tension the belt;
reduction in performance characteristics. We are talking about the destruction of communication elements with drying out. In the first stages, cracks appear on the surface of the element, and then further destruction occurs. During movement, individual belt fragments touch the pulley, which leads to slipping. In this case, the only way out of the situation is replacement;
generator wedge.

How to properly replace and tension the VAZ 2110 alternator belt (8 valves)?

Let us dwell on the procedure for tensioning the V-belt drive. If there is no visible damage to the element, it is necessary to check the tension level.

In accordance with the vehicle operating manual, a force of 10 kg/cm2 should result in a deflection of one to one and a half cm. It is impossible to check the tension without special equipment in this way.

Therefore, car owners use a practical method based on their own experience. This can be done in a simple way by pressing with a certain force on the product. If the element bends no more than 0.8 cm, then this indicates proper tension.

If the tension is strong or weak, the level of the V-belt drive must be brought back to normal.

In fact, the difficulty is not in the increased noise. Improper tension can result in two serious problems:

low level - the battery is not charging efficiently. Also in this case, the belt wears out faster;
strong tension - increases the likelihood of failure of the generator bearings.

In order to perform tension, you must perform the following steps:

use a nut to loosen the generator mount (in the lower and upper parts);
use the adjusting bolt to adjust the element;
to increase tension, the adjusting bolt must be turned clockwise;
after rotating the bolt, you need to check the tension level;
tighten the nut securing the generator.

Replacing the VAZ-2110 alternator belt

If there is no visible damage on the surface of the belt, then tension or loosen it. Other cases, including excessive stretching of the element, require replacement. To perform the work, you must adhere to the following sequence of actions:

use a nut to loosen the generator;
adjusting bolt, loosen the tension;
Move the generator slightly towards the engine;
remove the belt;
install a new element purchased from an online store or retail outlet. It is recommended to buy good quality products;
put the element on, and first this is done on the crankshaft pulley, and then on the generator;
perform tension adjustment settings;
tighten the generator mounting nut.

To replace the belt, the motorist will need several wrenches. You can also get by with one spanner.

After completing all operations, it is recommended to rotate the crankshaft and recheck the tension. To rotate the shaft, you need to engage fourth gear and roll the car forward a little. If necessary, the belt tension must be loosened or tightened. At the same time, it is important not to forget about the need to secure the upper and lower nuts of the generator until they stop.

It is not uncommon for a VAZ 2110 car to experience a whistle in the V-belt connection of the generator. For this reason, it needs to be tightened or completely replaced. Today we will talk in detail about the tightening procedure, and also tell you how it changes.

Tension adjustment using a roller

Adjusting roller and key for it

Some modern machines use special adjustment rollers to adjust belt tension. They allow you to quickly and easily tension the belt. As an example of using this method, consider adjusting the belt on a Lada Priora car with air conditioning and power steering, as one of the most popular cars in our country.

How to tighten the alternator belt on a Priora

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). Such a key can be purchased at any auto store for a nominal price. Some car owners use curved pliers or “duckbills” in their work. However, we advise you to still buy an adjustment wrench, given its low price and ease of further work.

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.

Hello, dear motorists! Well, let's move on to specific cars and their lovers?

“PRIOROVODY” - this is what the owners of cars of one of the latest VAZ series called “Lada” - “Priora” call themselves.

Many people liked the stylish and modern car. The deep-rooted belief that domestic cars are worthless is gradually dispelling. The cars have indeed become more comfortable and attractive, and their technical equipment has improved significantly.

Why does the whistle occur?

There are several reasons why the characteristic whistle-like sound occurs.

Weak tension. The element slips, and this happens most actively at night. The increased intensity of the whistle at night is explained by the fact that the generator additionally works for lighting.
Gradually the component is destroyed. The belt can dry out, causing its structure to be disrupted and it literally crumbles into pieces. The first signs are cracks, and then whole pieces break off. When moving, the pulley hits and slipping begins. Only replacement is required here.
Although moisture gets on the belt very rarely and evaporates almost immediately, the connection can still whistle. In this situation, tension is required.
The generator itself jams.

Dimensions

The sizes are different, and they are individual for each VAZ model.

If we talk specifically about the “ten”, then adhere to the following rules for choosing a belt size:

In the absence of air conditioning and power steering, 742 millimeters is suitable;
If the car is equipped with a hydraulic booster, then the size will be 1115 millimeters;
If an air conditioner is also present, then the optimal size is 1125 millimeters.

Some craftsmen regularly use original belts from other AvtoVAZ models - Priora and Kalina - to replace them when repairing their "ten".

Performing tension

The problem is not the whistling. Due to weak tension, the battery does not charge effectively, and the drive itself begins to wear out faster. Excessive tension can lead to damage to the alternator bearings and stretching of the belt.

Correct tension of the VAZ 2110 generator belt is performed as follows:

Loosen the generator from the bottom and top. A nut is used for this;
Turn the adjusting bolt and adjust the belt;
If you want to increase the tension, the bolt is turned to the right. Thus, you move the generator away from the cylinder block;
To loosen the tension, move in the opposite direction - to the left;
Use a wrench to grab the fastening bolt and turn the crankshaft a couple of turns, then check the tension;
If all is well, the tension is correct, the nut can be tightened back.

How to tension the alternator belt

Many car owners are interested in the question: how to tighten the alternator belt? After all, the battery charge level and the voltage in the car’s electrical network depend on this. Also, the condition of the belt itself, as well as the condition of the crankshaft bearings and the generator shaft, depend on how the generator belt is tensioned. Next, we will analyze in detail how to properly tension the alternator belt with a specific example.

Replacement

In fact, replacement cannot be called a complex procedure. Follow the instructions and everything will work out.

Slightly loosen the bolt nut from the lower mounting of the car generator, as well as the tension nut.
Loosen the tension of your belt further. You already know how to do this from the previous section, where we talked about tensioning the alternator belt.

conclusions

Replacing the alternator belt on a 16-valve VAZ-2112 engine is not an easy task, but it can be done with your own hands. So, the process itself can take about 3 hours . It is worth paying special attention to the quality of the product. It will depend on it how long it will last on the car.

Why do you need an alternator belt in a car? Even the most inexperienced car enthusiast can easily answer this question. But if there are still difficulties in determining the role of the generator belt, then in short, we can answer as follows. The alternator belt transmits torque from the engine crankshaft to the alternator shaft. And if the belt tension drops, the generator stops performing its function properly.

Signs of poor alternator belt tension

Probably everyone heard the whistle coming from under the hood when the car started moving. This is the kind of whistle that the alternator belt makes if it has low tension or needs to be replaced.

Also pay attention to the instrument panel after starting the VAZ engine. If the light bulbs change brightness after pressing the gas pedal, it means that the alternator belt needs tension.

Motorists Council

This is due to the fact that its breakdown can occur at the most inopportune moment. This node cannot be called the weakest point of the “ten”, but problems may arise with it. And it is better for you to be prepared for such a situation.

Otherwise, you will have to call a tow truck, go to the nearest service station, and pay a lot of money for the services of specialists. Although, if you have a spare alternator belt and a standard set of tools, if it breaks, you would spend literally a couple of tens of minutes and calmly continue driving with a new belt. Because the choice is always yours!

Belt generator VAZ 2112. stretching and replacing the generator belt yourself

Hello, dear motorists! VAZ tenth series cars quickly spread throughout our country.

The new design, economical engine and affordable price helped expand the circle of fans of these cars.

How to tighten or loosen the VAZ 2110, 2114, 2115 alternator belt

Cause and solution to the problem with whistling on the VAZ 2112

If the VAZ 2112 generator the belt

not dense enough. When the speed changes, the pulley rotates and the belt slides along its surface, creating a characteristic sound. In addition to the unpleasant squeaking noise, you need to be prepared for the fact that the belt will quickly overheat and may fail.

A highly tensioned VAZ 21124 belt generator can also lead to various breakdowns, the most common of which are:

wear and failure of generator bearings;
tape break;
curvature of the bracket.

Video instructions for tensioning or loosening the alternator belt on a VAZ 2110-2112

To show everything clearly and clarify the picture, I decided to record a short video that contains instructions in an accessible form:

Replacing the VAZ 2112 alternator belt in the garage with your own hands

As much as we don’t want, most machine parts have their own resource, after the development of which it must be replaced.

The VAZ 2112 alternator belt can provide a mileage of more than 100 thousand km provided it is of high quality and careful operation, but it is better to replace it without tempting fate after it has met the established production time.

Replacing generator tape 2112 in the following order:

The car is installed on a viewing hole, since access from the bottom to the belt is more convenient;
After disconnecting the battery, the upper and lower mounting nuts of the generator are loosened;
the adjusting bolt is loosened and the generator moves into the engine block;
The old one is removed and a new alternator belt is applied.

Belt tensioning is carried out as described above. Given that a new belt is installed, after a short period of operation it may stretch slightly and the tension will be relieved. Eliminate this by additionally tightening the generator drive belt to the parameters set by the manufacturer.

In what cases is replacement necessary?

Like any consumable material, the alternator belt has a certain resource and requires constant technical inspection. According to the recommendations of the manufacturer, on a VAZ 2112, regardless of whether there are 16 valves on the engine or 8, the consumables need to be changed after 45 thousand kilometers. But these are just recommendations; it is necessary to constantly monitor the condition of the product and change it in time. Service life depends on the following factors:

driving habits;
operating conditions;
product quality.

A visual inspection of the drive components should be carried out when the car has traveled a maximum of 10 thousand kilometers and before a long trip. This will make it possible to avoid unpleasant surprises along the way - a broken belt. It is recommended to carry a spare one with you in the trunk, since if it breaks, the car will no longer be able to move on its own.

The strap needs to be changed if it is torn, stretched or becomes unusable. Poor tension can be determined by a specific whistle that occurs when the engine starts. Tension plays an important role in the operation of a belt drive. If the tension is weak, the unit does not generate the amount of electricity necessary for normal operation of the car. If it is strong, the service life of the belt, drive bearings and crankshaft is reduced.

The need for replacement can be determined by inspection based on the following signs:

the appearance of cracks and tears;
worn surface;

Old product with worn surface
material delamination;
frayed edges;
strong stretch.

It's easy to check the strap tension. It is considered normal if, with a force of 10 kg, it bends by 10-15 mm. To check it, you need to press it with your thumb approximately in the middle of the belt between the crankshaft pulley and the generator.

Tension check location (where to press)

If the deflection is greater than normal, adjust the tension or change the product.
