The timing belt (gas distribution mechanism) is responsible for synchronizing the rotation of the crankshaft and camshaft. If it breaks, stopping the engine is inevitable, and in some cases, deformation of the valves, damage to the pistons and cylinder bores from their fragments is possible. Therefore, it is important to choose the right high-quality and compatible part. It is better to do this using the catalog or the markings on the belt, which, unfortunately, do not have a uniform standard.
When choosing, you need to know the number of teeth, their profile, and blade width. It is also necessary to pay attention to the production date of the timing belt, since the material from which it is made has its own expiration date.
This article will tell you how to choose a timing belt, how the markings on it are deciphered and how to determine the year of manufacture.
VAZ timing belts on AvtoVAZ cars
Toothed timing belts used on Lada models for replacement...
Greetings to all VAZ car enthusiasts in my auto blog RtiIvaz.ru. Today we will look at the timing belts used on your Lada cars.
In front of us lies on the hood of my Renault Logan car one of the belts to be replaced (see video). Let's first find out what a toothed rubber drive is used for. The timing belt serves to transmit the rotational movement of the crankshaft to the camshaft, whose task is to open and close the intake and exhaust valves in a strictly defined sequence. This rubber drive has 111 teeth and is designated with the number 111-19 II CR, manufactured by the Balakovo rubber plant BRT.
On cars “Kalina”, “Priora”, as well as VAZ-21012 and other models with a V8 engine, exactly the same strap of 111 teeth, 19 mm wide, is installed.
For VAZ 2110, 2111, 2112 cars with a sixteen-valve engine, a timing belt with a number of teeth of 136 and a width of 25.4 mm is used. Its number is 136-25.4 HNBR. If we compare this drive with a 111-tooth drive, then for sixteen valve engines it is 6.4 mm wider.
The next strap is designed for the VAZ-2170 Priora. This strap has 137 teeth and is 22mm wide. Its designation is 137-22 HNBR. Also suitable for model 2190 “Grant”, VAZ-1118 “Kalina” with a sixteen valve engine. Please note that they have a 21126 engine installed. Such an engine can be installed on VAZ-2112 models, which also use a rubber gas distribution mechanism drive, the number of 137 teeth, 22 mm wide.
Next, let's look at the strap from the VAZ-2190 Lada Granta model with an eight-valve engine. This timing gear drive has 113 teeth and is 17 mm wide (113 SP 170 H). It is similar to the timing drive from the VAZ 2108, but is slightly narrower in width and has two more teeth - please do not confuse it when purchasing.
As mentioned above, for the Lada Granta, which has a sixteen-valve engine, there is a timing belt of 137 teeth, 22 mm wide.
The more valves in the engine, the more powerful the drive, since the engine power increases, so the load increases proportionally.
Watch the video below, it shows all the timing belts used on eight and sixteen valve engines of the family of AvtoVAZ front-wheel drive models.
Let's look at the photos in order:
- Timing belt for VAZ-2108, 2109, 21099, as well as other models with the 2108 engine - 111 teeth, width 19 mm. Design number: 2108-1006040-10.
- Timing belt for VAZ-2112 - 136 teeth, belt width 25.4 mm. Design number: 2112-1006040.
- Timing belt VAZ-2170 "Priora" - 137 teeth, belt width 22 mm - engine 21126 sixteen-valve. Design number: 21126-1006040.
- Timing belt for VAZ-2190 "Lada Granta" 113 teeth, width 17 mm - engine 21116 eight-valve. Design number: 21116-1006040.
For front-wheel drive AvtoVAZ models, four types of timing belts are produced, which have a different number of teeth and different widths, which creates some confusion when purchasing them. I hope that this video and photo will help you understand the timing belt size used specifically for your VAZ car model. Video:

Dear customers, in order to avoid errors when sending the POWER GRIP 5521 timing belt, in the “Comment” line indicate the model, year of manufacture of your car and the number of valves, engine size.
The simplicity of the design lies in the fact that rotation is transmitted from one shaft to another using this part. Each type of engine has its own design features, which is why the belts are produced differently.
Their differences are assessed according to the following parameters:
The part experiences heavy loads, so it must be strong, elastic, and provide good interaction with the pulleys and rollers.
High-strength polyester cord of GATES belts increases the belt's ability to withstand heavy loads, maintains stable belt tension and provides excellent belt length stability. The upper part of the fabric layers provides elasticity and flexibility. Premium fiber-reinforced chloroprene rubber (strong fiber optic tension strands are helically laid to provide increased flexibility and tensile strength) makes the belt resistant to oil, heat and wear and prevents deposit build-up.
Thanks to their successful design, they retain their length throughout their entire service life.
Main technical characteristics
The timing belt profile is trapezoidal and meets the requirements of US, UNECE and Russian GOST standards. The main dimensions of the belts are indicated on the packaging.
The toothed belt has an internal profile of protrusions (teeth), the number of which is 111, with a width of 19 mm.
During the production process, all belts undergo 100% quality control in terms of geometric dimensions and control tensile strength. All stages of production, as well as suppliers of component materials, are certified for compliance with the requirements of the ISO 9001 standard. Identical technologies and materials are used in the production of timing belts, which are supplied to the assembly lines of VAZ, GAZ, UAZ, General Motors, Ford, Daimler-Chrysler, Toyota, Honda and other car manufacturers.
The optimal combination of materials allows for high wear resistance of belts and low noise levels. In addition, US GATES belts can operate over a wide range of tension forces without significantly compromising durability, reducing the risk of belt failure due to improper belt tension adjustment.
The estimated service life of USA GATES timing belts is 125,000 km or 2 years.
Monitoring the tension and condition of timing belts must be carried out during each scheduled vehicle maintenance.
Before replacing the timing belt, you need to check and pay attention to the following:
- if the belt is damaged, it requires replacement;
— check the degree of tension;
- The belt must be dry and clean.
The design has a tension roller; the whistle may be a result of its wear. Replacing the part completely solves the problem.
If the cause cannot be determined, the belt should be replaced with a part from another manufacturer.
Timing belt rupture can be caused by the following factors:
— natural wear and tear (operation was carried out beyond the established period);
— the part was initially defective;
— malfunction of pulleys, shafts, tensioners;
- excessive or insufficient belt tension.
The bearing is the most vulnerable part and often fails. Once the belt is removed, it is easy to diagnose bearing failure.
Roller with offset center. When rotating, the belt is tensioned, the degree of tension is fixed using a bolt.
It is important to monitor the condition of the timing belt tensioner roller. It is the roller that makes the tension level of the belt drive optimal.
It is necessary to check the condition of this part and make repairs if necessary.
There are three tension options:

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.

Well then, either AvtoVAZ or Balakovo! The belts are good and the most common; there is no point in counterfeiting them, since these are not expensive spare parts.
They themselves suck. My grandfather's car does this a little. He says he changed the timing belts a lot. Our Russians are the most eager. I'll probably take the Bosch, the reviews are praising it
I drove an AvtoVAZ for 2 years - 50 thousand km. I drove to Balakovo for 2 years - about 60 thousand km. Nothing ever broke.
Well, maybe it also depends on the frequency of driving and driving style. Now I will be doing a lot of long-distance driving, I’d rather not take risks with Russian timing belts.

Dimensions
It is quite possible that you have selected the wrong alternator belt size for your 16 valve VAZ 2110. This often causes whistling. The correct size of the alternator belt for the 8 valve VAZ 2110 should be determined in advance, even before going to the auto parts store.
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".

Involute, pitch 9.5, width 19mm. The profile when I was interested in this question did not come across “at random”, I need to dig through the catalogues. If any information appears, please share it here.
Look towards more modern models of Lada, there is a round tooth very similar to the HTD-8-M, despite the fact that the gears are not much more expensive than eight-wheel gears. I bought the gears for myself to try, but I still haven’t gotten around to the belts to try them on.

Volodya, slow down your horses.
Go to the auto shop, ask for gears on the Lada Kalina, Renault Logan and some Lada heel with a similar muzzle to the Logan. HTD8M should be there. Cost compared to erosion. In general, gasoline will be more expensive to get there
Sent after 1 minute 1 second: Did you download the program from contitech? Well, what about checking the loads and diameters?

so I can cut out both gears with wire and it will be cheaper than one sprocket costs in the store
I only downloaded the program GearTrax_SE_2017 because There are no loads for such a belt, the handles can be turned by hand well, I am redoing the machine, now I installed 21 and 42 gear teeth just from the pump and from the camshaft, the motor got strained under a full table and wedged with gaps, I decided to double the reduction, I drew 12 and 48 teeth, the same profile
What's the result?
Except for Gates belts with involute teeth, all samples performed well. The Russian product performed no worse than imported ones, despite the fact that the belt is noticeably cheaper.
Well, among the imported products, the most affordable (and at the same time good) belts are Contitech and Lemforder. Italian Dayco belts are a little more expensive and at the same time showed a small margin of strength during tensile tests. Roulunds and Bosch belts are also good, but much more expensive than others.

Timing belt VAZ 2109
The VAZ-2109 car was produced for many years by various factories in the Soviet Union, Russia, CIS countries and abroad from 1987 to 2011. All parts and mechanisms of the car are subject to wear and tear as they are used. This includes the timing belt on the VAZ 2109. The reason for this may be poor-quality and careless installation of the belt during timing assembly, wear of associated parts, or poor quality of the belt itself. Standards require belt replacement every 60-65 thousand km or after 4 years of operation.
Step-by-step replacement instructions
The VAZ 2109 car is designed in such a way that if repair work is necessary, it can be carried out by the car owner himself. The process of changing the tensioner roller is quite simple, and it will take no more than 1.5 hours.
Step-by-step instructions for carrying out technical work on the timing system:
hidden spring roller
roller with external spring design
If after the work carried out, the car owner has no complaints about the operation of the engine, then the process of replacing the timing rollers in the engine is over.
Malfunctions after replacing timing rollers
In most cases, after replacing the timing belt tensioners, the car owner does not encounter any problems. However, as practice has shown, malfunctions can manifest themselves after some time.
Malfunctions and solutions:
Fault 1: The battery does not charge well; after several hours of inactivity, the car does not start. Voltage drops are also observed in the on-board electrical network.
Solution: Most likely, when installing the timing belt, the driver incorrectly adjusted the position of the shaft gears in relation to the generator gear. As a result, malfunctions in the on-board network began to appear. They arise due to the asynchronous operation of the gears described above. To eliminate this problem, you just need to debug the position of the shaft gears and the generator. After additional configuration, the problem goes away.
Malfunction 2: After replacing the rollers, the timing belt cracked or even broke.
Solution: In most cases, this problem occurs when a modified timing panel panel is installed. Such breakdowns occur due to the fact that the position of the rollers was not calibrated, as a result of which the belt was overtightened. To eliminate this problem, remove one of the rollers, then put on the belt. After this, install the removed roller back on the panel. Then adjust its position. The adjustment itself must be carried out using a special wrench, which must be used to tighten additional screws on the tensioner. When adjusting the position of the roller, you should also rotate the belt to ensure that there is no excessive pressure on it.
If any other problems occur in the engine after replacing the rollers, a simple solution would be:
Despite everything, I would like to emphasize that the VAZ 2109 car, although it is the brainchild of the domestic automobile industry, can serve its owner for many years with proper care.
Timing belts
This important car part is produced by various companies - BOSCH, AMD, CONTITECH, DAYCO, FEBI, GATES, HEPU, INA, NTN-SNR, OPTIMAL, RUVILLE, SKF.
Both repair kits - belt and rollers, and each part separately are available for sale. Prices vary depending on the manufacturer and place of sale:
- The GATES repair kit for the VAZ-2109 costs approximately 1,100 rubles.
- Contitech - 1250 rubles.
- “BRT” (158 RU) - 1000 rubles.
The repair kit includes a belt and a tension roller. The belts have one side (top) flat, the other in the form of oval teeth. The surface of this side is figuredly corrugated. There should be no tears at the base of the teeth. You should buy only branded belts; fakes pose a hidden threat.
The original differs from a fake, first of all, in packaging. The box must be made of high-quality cardboard, neat, with clearly printed inscriptions. The original box has a transparent sticker on which is printed a list of engines for which this repair kit is suitable, a diagram of the assembled drive with all the pulleys and rollers, the number of teeth on the belt, and a QR code.
Using it, you can go to the company’s website and get all the detailed and reliable information about the product. For example, the Contitech box has the article number CT527 printed on it.
On counterfeit boxes, all information is printed directly on the cardboard of the box. On the original box it is clearly written in which European country this belt was made. The spare part in the box is packed without kinks or kinks. The tails of the cord stick out along the edge of the belt.
Originals and fakes from other companies are checked using the same criteria. GATES packages have a security hologram. Article number 5521XS-111x, which means that the belt is reinforced, 111 teeth. The company logo is printed on the belt and roller.
This table shows the original repair kits with the article number and approximate cost.

The need to replace the timing belt
If the tension roller is installed incorrectly or the belt tension is too strong, its pin is deformed, the roller tilts slightly, and the belt slips. It may begin to cling to protruding parts of the machine. If suspicious places are found on the belt - deep scratches, abrasions, dents or tears in the teeth - the belt must be replaced immediately.
There should be no traces of oil on it. Firstly, this indicates a seal leaking somewhere, and secondly, the belt itself is in danger. If the belt breaks while the engine is running, the timing valves may collide with the pistons and bend. And on a VAZ-2109 with an 8-valve engine, if a belt break happens on the road, then this situation will not be fatal for a skilled driver. You just need to know what actions to take in this case. And, of course, it never hurts to have a spare timing belt.
Audi 100
In general, Audi modernized almost all engines in 1991. Thanks to it, the optimal power values have shifted in the direction of cutting speed. Thus, this directly affected the nature of the tension of the rubber timing ring.
You should know that initially the belt on the Audi was tensioned using a pump. This was actually done only once, and then when replacing, a new belt was installed without any adjustments.
After modernization, instead of a stationary roller, a movable one equipped with a temperature compensation system was installed. This roller assembly was supplied assembled and cost about $130, but the owners rarely used the original ones and installed duplicates for $20 in order to save money when replacing them. But as a result of this, some Audi owners began to have problems; the belt periodically shifted and slipped out of place.
The task of adjusting the Audi timing belt comes down to ensuring that the belt can be twisted 90*, or in other words, one quarter of a full turn. Below are instructions on what and how to do if the tension is too strong or too weak.
This thermal device lasts for approximately 150 thousand miles, but there are exceptions.
Procedure
The car must be put on the brakes and engaged in fourth gear. The first step is to place a jack, lift the car and remove the front right wheel. This will provide access to the area required for maintenance. Then you should remove the boot cover from the timing drive mechanism. It is secured with three 10 mm socket bolts.
This gives access to the generator pulley. It also needs to be removed. This is not always easy, as the nut often rusts and gets stuck.
With the alternator pulley removed, access to the timing belt is available. After carrying out these operations, you should check the coincidence of the marks on the timing sprocket (the mark in the form of a bump) and the slot on the housing. If there is no match, then they must be combined. This ensures control of the engine's top dead center.
Now you can remove the old belt. After removing it, you need to set the timing marks on the gear on the crankshaft and on the car body. If it is inconvenient to turn the crankshaft, you can engage fourth gear and push the car forward a little.
After completing this operation, you can install a new belt. There is a special roller for tensioning it. It is usually sold complete with a belt. If the old roller looks worn, it must be replaced with a new one.
Due to the presence of eccentricity, turning the roller ensures belt tension. The rollers of the new design have two holes on the plane; pins are inserted into them, and a lever is installed between them, with the help of which the tension roller is turned. The rollers on the VAZ-2109 carburetor have a 36 mm nut, due to which the roller was turned using a spanner.
The normal belt tension is determined manually. With light force, the plane of the belt can be rotated 90 degrees with two fingers. After tensioning, the roller is fixed with a 17 mm lock nut.
After the timing belt is properly tensioned, the alternator pulley is installed in place and the alternator pulley is fixed; the alternator belt should be carefully pulled onto it. After this, the timing belt protection and the right wheel are installed. Then the car starts and if all the symptoms that were on the old timing belt are absent, then the job is done successfully.
Replacing a timing belt is considered a rather difficult job, but quite accessible to an averagely qualified mechanic. In the end, it must be said that in order to prevent situations of rupture or unexpected wear of the belt right on the road, it should be replaced in a timely manner and preventive maintenance of the car should be carried out.
Main stage
- After these steps, you can proceed to the main stage. First of all, you will need to remove the right engine mudguard. Sometimes it is enough to unscrew the two mudguard screws with a wrench to open access to the crankshaft pulley.
- The next step is to remove the alternator belt. To do this, you will need to unscrew the nut of the lower mounting bolt. Then you need to move the generator towards the engine and remove the belt itself.
- The third step is to remove the protective cover. The work is done using a key. The cover is secured with three bolts that will need to be unscrewed.
When the above work is completed, it will be possible to make a replacement. For successful work, you will need to align the installation marks of the part elements. If this is not done, all steps will have to be performed again.
As for replacing the timing belt on a VAZ-2108, it is performed as follows:
- Loosen the timing roller mounting nut using a 17 mm wrench. The loosened roller is turned counterclockwise to reduce belt tension.
- Remove the faulty timing belt. To do this, it is shifted from the pulley and removed from the tension roller.
- Install a new part purchased in advance. It is important to ensure that all the necessary marks match, otherwise the process will have to be repeated. After installation, you will need to tighten the belt with a nut.
To properly tension, you need to insert a key into the hole in the tension roller. After this you will need to turn it clockwise. The belt will begin to tighten and it is important to stop the action in time to avoid achieving too much force.
Once the belt is tightened, you will need to check its tension. If all actions are performed correctly, the part will rotate 90 degrees. Otherwise, you will have to loosen the tension until the required value is achieved.
The final steps to replace the belt will be:
- Tightening the tension roller nut.
- Reinstalling the crankshaft pulley.
- Fastening the timing cover.
- Wheel installation.
- Lowering the car from the jack.
- Battery connection.
Only after this will it be possible to start the engine to check the operation of the correct replacement. If the car starts without any problems, then the replacement was successful. If the malfunction does not disappear, it is recommended to seek help from a service station.
To change parts, it is worth considering that they have marks that need to be connected. For example, there may be no identification mark. In this case, for a high-quality connection of the parts, it will be necessary to install the gear shaft pulley in the center of the cut on the lower ebb of the cover.
To avoid frequent replacement of the timing belt in the engine, it is recommended to regularly inspect the vehicle. This way, it will be possible to identify a possible problem in advance and fix it much faster and cheaper.
