Timing belt marks grant 8 valve. The process of replacing the timing belt at the fret grant

Dear buyers, in order to avoid mistakes when sending p Timing belt POWER GRIP 5050 XS , in the line "Comment" indicate the model, year of manufacture of your car andnumber of valves, engine displacement.

The simplicity of the design lies in the fact that rotation is transmitted from one shaft to another with the help of this part. Each type of engine has its own design features, therefore belts are produced differently.

Their differences are assessed according to the following parameters:

Length;

Width;

The number of teeth.

The part is under heavy loads, so it must be strong, elastic, and ensure good interaction with pulleys and rollers.

High strength polyester belt cord"GATES »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 spirally wound for increased flexibility and tensile strength), gives the belt oil, heat, and wear resistance and prevents sludge build-up.

Thanks to the successful design, they retain their length throughout the entire service life.

Main technical characteristics

The timing belt profile is trapezoidal, meets the requirements of the 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 113 projections (teeth), 17 mm wide.

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 ISO 9001. Identical technologies and materials are used in the production of timing belts, which are supplied to assembly lines VAZ, GAZ, UAZ, General Motors, Ford, Daimler-Chrysler, Toyota, Honda and other car manufacturers.

The optimal combination of materials allows to achieve high wear resistance of belts, low noise level. In addition, the straps"GATES »The US can handle a wide range of tensioning forces without significantly compromising durability, reducing the risk of belt failure due to improper tensioning.

Estimated service life of timing belts"GATES »USA - 125,000 km or 2 years.

Monitoring the tension and condition of timing belts must be carried out at each scheduled maintenance of vehicles.

Before replacing the timing belt, you need to check and pay attention to the following:

If the belt is damaged, it needs to be replaced;

Check the degree of tension;

The belt must be dry and clean.

The design has a tension roller, the whistle may be the 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.

A break in the timing belt can be caused by the following factors:

Natural wear and tear (operation was carried out over the established period);

The part was originally defective;

Malfunction of pulleys, shafts, tensioners;

Excessive or insufficient belt tension.

The bearing is the most vulnerable part that often fails. After the belt is removed, it is easy to diagnose the bearing failure.

Off-center roller. When rotating, the belt is tensioned, the degree of tension is fixed with 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, if necessary, make repairs.

There are three tension options:

Insufficient;

Excessive;

Normal.

How to replace the timing belt yourselfby car of the Lada Granta family.

With the Internet - Shop AvtoAzbuka repair costs will be minimal.

Just COMPARE and MAKE SURE !!!

It serves to timely open and close valves in the block head. Such a mechanism is also available on the Lada Grant. However, there are two types of drive - chain and belt. If we talk about "Grant", then it is the second type that is applied here. It must be said that such a drive is quieter, but less reliable. The chain is always more difficult to break than the belt. However, if you observe the replacement interval, you may not encounter a break. And in today's article we will pay attention to replacing the timing belt "Lada Grants".

How it works?

The principle of operation of this element is quite simple. First, let's tell you about the location. And this element is located on the side of the crankshaft pulley. Since the "Grant" has a transverse engine, the belt is located on the side of the right front wheel. Unlike a chain, it does not require lubrication and therefore can be installed openly. The belt has special teeth on the inside. Thanks to them, the element engages with several parts at once:

Thus, when the first shaft rotates in a chain reaction, the rest of the elements also rotate. And since the belt is flexible, it is pulled with a special roller for high-quality engagement. Thus, the two shafts rotate synchronously. It is unacceptable for the belt to jump one or more teeth. Otherwise, the intake and exhaust settings are instantly lost. This will immediately be felt on the nature of the car's behavior. The car will triple, consume more fuel and not pull.

How often to change?

According to the regulations, it is required to replace the timing belt on a Lada Grant with an 8-valve engine every 75 thousand kilometers. However, the manufacturer recommends checking its condition every 15 thousand kilometers. It often happens that the belt has lost its tension or has acquired signs of wear ahead of schedule.

Signs of wear

How to understand that a given element is out of order? The first sign indicating the need to replace the timing belt on the "Grant" is a significant wear of the material. This usually occurs due to poor performance of the idler roller bearing or a deviation in its position. So, at high humidity, the belt can jump by one or several teeth.

It is important to carefully check the external condition. So, the belt must be replaced if there are tissue remnants, cracks or delamination on it. The more of these defects, the higher the likelihood that the element will suddenly break. Do not use too hard belt. This will be indicated by the characteristic brilliance of the element. Because of this, high-quality contact with the engine crankshaft pulley is not ensured. What brand should I choose a new belt? It is not necessary to purchase the original. There are several good analogs:


But do not buy too cheap analogs. Otherwise, no one can guarantee that such a belt will serve 75 thousand kilometers specified by the manufacturer.

Training

For work we need a standard set of tools, a new belt with a roller, as well as a roller wrench. It will not be superfluous to buy a new alternator belt, since we will also be removing it.

It is not necessary to carry out work in the pit. It is enough to unscrew the right front wheel for convenience. So, you need an additional wheel wrench and a jack. Place anti-roll bars under the machine before lifting.

Getting Started

So, first we need to remove the plastic protective cover. This can be done using a 5 Allen key. The cover is secured with four screws. If the motor 11183 is installed on the "Grant", here you need a key for 10 for this. It is enough for them to unscrew the three fastening bolts. Next, the crankshaft position sensor is removed. The fastening screw is unscrewed with a 10 spanner. The DPKV is also dismantled.

Setting labels

Now it is important to install the crankshaft and camshaft according to the marks. To do this, turn on neutral. Remove the rubber cover on the crankcase (closer to the clutch). We need to align the marks in the scale slot and on the flywheel. Then the latter is fixed with a minus screwdriver. The crankshaft itself can be rotated with a 17 or 19 key (depending on the specific type of motor). Better to perform this operation together. While one rotates the shaft, the second fixes the position of the marks. The main thing is that they match exactly.

What's next?

Then you need to remove the alternator belt. This is the only way to get to the timing belt "Lada Grants". We loosen the tensioner and remove the generator drive. With a 13 key, loosen the lower fastening bolt and unscrew the upper fastening nut. The bolt can also be removed. The generator casing is pressed against the engine by means of a wire and fixed.

Change the belt

When the flywheel is fixed, using a 19 or 17 key, unscrew the bolt that holds the generator drive pulley. The pulley is dismantled together with the washer.

  • If it is an 11183 series engine, use a 17 key to loosen the retaining nut. The roller itself rotates clockwise.
  • On other engines, a head 15 is used. It is used to unscrew the bolt by about three turns. Then the roller will release the belt on its own.

Now we just have to remove the old belt and install a new one. Timing on "Lada Grant" with an 8-valve engine is performed in reverse order. To tighten the outer part of the roller, rotate counterclockwise. In this case, the two marks (rectangular) must coincide with each other. After installing the element, it is worth checking the labels again.

As for the alternator belt, it is installed in the following sequence:

  • First, the generator itself is mounted.
  • Next, the belt is put on the pulleys.
  • Having turned on the fifth gear, they roll the car back.

That's all. Belt replacement completed successfully. You can start full-fledged operation of the car.

About tightening torques

When changing the timing belt on a Lada Granta car, it is important to use a torque wrench. So we will know for sure that the bolts and all connections are properly tightened and, most importantly, not overtightened. Depending on the type of part, the following values ​​are set on the key:


Please note: when changing the timing belt on a "Lada Grant" with an 8-valve engine, first adjust the tension on the roller. And after that, the fastening bolt is tightened.

Conclusion

So, we found out how the timing belt is replaced on the Lada Grant. As you can see, this operation can be performed independently. In total, the replacement will take about two hours. But if the work is not done for the first time, then the time can be cut in half.

All the latest models of front-wheel drive cars, which are produced by the automobile plant located in Togliatti, have a timing belt in the timing mechanism. Lada Granta fully refers to these models.

The car is equipped with several engine modifications, which can have 8 or 16 valves in the cylinder head. Many owners service and repair this model on their own, so it will be useful for them to learn about how to change the timing belt on a Lada Granta with 8 valves.

Lada Granta motors with 8 valves in the cylinder head have an index of 11183 and 11186. The first of them began to be produced in 2004, the second later, namely in 2011. The power of the "83" unit is 82 horses, at 87 hp for the "86" modification. The 11186 engine is an improved model “83” engine. It uses a lightweight connecting rod and piston group. It was possible to achieve a reduction in the mass of the piston group by almost 30%. The cylinder head is subjected to a specific heat treatment, which increases its strength and wear resistance.

And also the cooling system of the power unit received some changes. The skirts of lightweight pistons are coated with graphite grease, this avoids the appearance of scoring on the cylinders of an unheated engine. The compression ratio "86" of the engine was 10.5 against 9.6 for the "83" modification. The cylinder head gasket of the new engine is now thinner, it is equal to 0.43 mm versus 1.2 on the old model. The diameter of the intake valves was increased, which improved the filling of the cylinders with the air-fuel mixture.

Does the valve fold

This problem, unfortunately, is present for Lada Granta. It appeared from the moment the production of the first cars with front-wheel drive VAZ 2108 began. Later, the working volume of the power unit of this model was increased, it became equal to 1.5 liters. The engine index became 21083, in which the pistons have a recess in the head. This made it possible to exclude the meeting of the pistons with the valves when the toothed belt in the timing belt breaks or if it is incorrectly installed. It was this power unit that was taken as the basis for the engine for Grants, so the valves did not bend.

The upgrade of this motor to model 11186 provides for the installation of lightweight parts of the connecting rod and piston group. The piston has become shorter in height, which does not allow making recesses in the head to avoid meeting with the valve. Therefore, a break of the toothed belt is always accompanied by damage to the valves on the 8 valve Grant, sometimes connecting rods, pistons. This problem accompanies all subsequent modifications of engines for Lada Grant.

Replacement procedure

Many owners of this car prefer to carry out this operation in specialized workshops, but some do it themselves. There is nothing super complicated in this procedure, there is no need to purchase special equipment or devices. You can replace the toothed belt in the garage yourself. You will need to prepare a set of wrenches, a mounting spade, a jack, a support for the body, wheel chocks, gloves, and rags. Use round nose pliers as a key for adjusting the tensioner roller.

Replacing the timing belt on the Lada Grant is performed in approximately the following sequence:

  1. The car is installed above the inspection pit or on a flat surface, the handbrake cable is tightened, and chocks are installed under the rear wheels.
  2. Open the hood of the engine compartment, disconnect the terminals from the battery.
  3. The drive belt of the generator set will interfere with work, so it is removed.
  4. Now "5" with the hex number unscrew the four screws that secure the front protective casing of the timing drive.
  5. To avoid accidentally damaging the crankshaft position sensor, it should be removed from the cylinder head and set aside. Do not allow metal filings to come into contact with the sensor, they may distort its readings in the future.
  6. Next, you need to set the piston of the first cylinder to the top dead center position.
  7. Removal of the toothed belt is interfered with by the alternator drive pulley on the crankshaft, which must be removed. To do this, rip off the wheel bolts of the right front wheel, raise the body with a car jack.
  8. A stand is installed under the body, the wheel is removed, the protective shield is on the mudguard.
  9. An assistant is needed to remove the crankshaft pulley. Ask him to put in fifth gear and push the brake pedal hard. Some specialists insert a powerful screwdriver into the hatch on the gearbox cover between the flywheel teeth.
  10. Applying some effort to the head "17", unscrew the bolt, remove the pulley from the crankshaft.
  11. Again, you need the fifth hex number, which you need to unscrew the three screws of the lower timing case, then you can remove the protection.
  12. Now it is necessary to loosen the tension roller fixing bolt, the “15” spanner wrench is best suited for this. After that, the roller will turn, release the tension on the drive belt, which can be easily removed from the toothed gears and removed from the engine compartment.

Important! After that, the engine crankshaft must not be turned so that the pistons do not meet the valves.

Usually, the belt is replaced in conjunction with the idler roller and the coolant pump, so they must be removed from the cylinder block. There is an adjusting washer under the roller, which is installed back during assembly. When removing the pump, a certain amount of antifreeze is poured into a previously prepared container. The installation of a new timing belt is carried out in the reverse order. Please note that you need to check the position of all alignment marks on the crankshaft and camshaft, the cylinder block and the timing case.

Setting labels

This is an important procedure when replacing a timing belt and must be taken seriously. This motor has four timing marks. Two on the crankshaft and camshaft gears, one on the cylinder block in the area of ​​the crankshaft, the last on a metal protective casing. Two more marks are located on the flywheel and gearbox housing. They will be clearly visible when the rubber plug is removed. It is the marks of the flywheel and the box casing that will indicate the position of the piston of the first cylinder at top dead center.

The crankshaft is turned clockwise with a “19” wrench until all marks of the mechanism match. The tapered groove or tide mark on the camshaft pulley will be horizontal and aligned with the lip on the guard. The mark on the crankshaft pulley will look strictly vertical and coincide with the mark on the cylinder block.

Tension

The installed new toothed belt must be tensioned to the required parameters. Before that, be sure to check the position of the alignment marks again, if everything is in order with them, you can tension the drive. To do this, turn the tension roller counterclockwise until the marks on it coincide. One mark in the form of a cutout is on the outer cage, the second on the inner one in the form of a ledge. You can turn the tension roller with a special wrench, round-nose pliers.

Some craftsmen insert drills suitable in diameter into the holes on the moving part of the roller. Between them, a screwdriver as a lever and turn the clip until the marks coincide. Then you can tighten the tension roller fixing screw. After all the work has been done, it is necessary to manually turn the crankshaft a few turns, making sure that the marks have not moved. Then you can install the protective cover.

How long does it take to replace

The factory operating manual for the car recommends replacing the toothed belt with a mileage of 75 thousand km. This norm is not always fulfilled by the owners; there are good reasons for this. How long the drive takes before replacement depends on many factors. This is the quality of the parts used, the operating conditions of the vehicle, the technical condition of the engine. At each maintenance, the tension and condition of the timing drive should be checked. When cracks, delamination, or other damage appear, the belt is changed.

With a high mileage of the machine, natural wear of the crankshaft and camshaft pulleys occurs, this significantly reduces the service life of the entire timing drive. And also the drive is afraid of engine oil getting into the belt operation zone. It softens its structure, the teeth are easily cut off. If the car has been standing still for a long time, it is also better to replace the drive due to its aging. Most owners, experts recommend changing the belt after a run of 50 thousand km.

Which kit to buy

In addition to the toothed belt, a tension roller and a coolant pump are purchased. The main supplier of rubber products is the RTI plant in Balakovo. Products from the companies GATES, BOSCH, DAYCO, CONTITECH have proven themselves well. If the pump in the engine cooling system is replaced, you will need antifreeze to top up.

The release of the domestic modification Lada Granta has been carried out for several years. The car has gained significant credibility due to its acceptable quality and level of performance, as well as the presence of several different versions of the equipment.

Today we will figure out when to change the timing belt, as well as which timing belt is better.

Some general provisions on the belt

The timing in any engine serves to ensure the timely admission of the prepared mixture and the release of exhaust gases. The composition of this node implies the presence of such elements:

  • camshaft and crankshaft;
  • the valves themselves with oil seals, springs, guide bushings and other parts.

Which timing belt is better? Separately, in the specified mechanism, the belt mechanism is positioned, acting as a connecting link between the camshaft (or two) and the crankshaft. It is the belt drive that is able to provide synchronization in the functioning of the elements included in the timing kit.

Finding this important element on the motor will not be difficult. To do this, you just have to open the hood lid of the Lada Granta and you will see a closed with a special casing. This protection prevents contamination and the ingress of foreign objects and dirt.

The design of the belt mechanism includes a rubber base and a working inner surface made in the form of teeth with a certain pitch.

What are the AvtoVAZ factory regulations in terms of replacement?

Cars of the Lada Granta model line are equipped with various versions of the power unit. Some of them are not without problems in the event of an unpleasant breakage of the belt drive. This is caused by the collision of the pistons with the valves, as a result of which the latter are bent, and the motor requires repair.

The possibility of bending (if a break occurs) is absent on the 11183-50 version of the motor, which is equipped with the standard equipment.

Another not unimportant question: when to change the timing belt? To exclude this unpleasant situation, the manufacturer deliberately regulated the periodic period for the mandatory replacement of the specified "consumable". The answer to the question of how long to change the timing belt from the manufacturer's company is after 15 thousand kilometers. This requirement applies to both 8-valve motors and their 16-valve modifications.

Even in spite of the equipment of the modification "21116" with a motor with an imported head, if the belt breaks, a similar sad fate awaits him.

The manufacturer does not recommend independent implementation of the procedure for checking the condition of the belt and for replacing it. And therefore, when the time has come to change the timing belt, you should contact the service center. If the fact of the handwritten execution of the indicated operation is revealed, the probability of depriving the owner of the possibility of warranty service is high. For self-replacement, the manufacturer grants permission regarding:

  • cabin filter;
  • a similar element for the intake system.

However, on their own, many car owners still carry out the replacement, but not all newly-made drivers know how much to change the timing belt, and also which timing belt is better than the rest.

Many owners of Lada Granta, especially those equipped with 16-valve versions of power units, recommend not to wait for the coveted mark of 60 thousand km. This is due to the possibility of using low-quality components capable of provoking wear of the replaced elements after a run of 20 thousand km.

This fact prompts many "Grantavodov" to resort to the use of products with good quality, and many of them, when asked which timing belt is better, answer that from the manufacturer "Gates". But we note that there are fakes of spare parts of this brand, and therefore, it is recommended to stop at purchasing items only from trusted suppliers.

If you set out to replace the component yourself, then you should not neglect some of the following guidelines. In particular, do not forget to observe the interval after how much to change the timing belt.

After hitching the belt, it needs to be tensioned correctly. This is done through the use of a specialized key. Some "leaders" will object, they say, you can do without him. However, here it is very problematic to dare to guarantee a high-quality result.
The force applied to the belt branch (when turning it through a 90-degree angle) located between two shafts (commonly known: camshafts and crankshafts) should not exceed 20 Nm, but it should not be less than 15 Nm either. If there is no "hit" in the indicated interval of parameters, then this indicates an incorrect belt tension. The consequence is one - a new adjustment!

What are the signs of a worn out belt?

The indicated factors will make it possible to accurately determine the moment of the onset of damage to the Lada Granta belt, which will prevent an unexpected onset of its failure (breakage). When to change the timing belt, how to understand that it is worn out?

  1. Among the primary signs, there is a significant degree of material wear. This fact will easily provoke a slipping or breakage of the "consumable" with an insignificant load on the motor or in conditions of high atmospheric humidity.
  2. The appearance of wear is often provoked by a violation of the correct position of the roller in relation to the pulley. This can be confirmed by the increased heating of the bearing and the fabric remnants of worn out cords sticking out to the sides, which are used to reinforce the rubber base of the belt.
  3. The next sign will be the fact of the presence of cracks and delamination. The greater the number of these defects, the higher the chance of a speedy belt break.
  4. If excessive hardness appears on the back surface, then it can be betrayed by the presence of gloss. This factor, associated with a loss of elasticity, indicates a loss of sufficient contact between the belt and the pulleys.
  5. During operation, it is possible to lengthen the belt surface, which can provoke its jumping on the teeth of the shaft pulley. Replacing the belt in this case is unambiguous.
  6. Failure of the roller, as a direct evidence of incorrect positioning of the belt in relation to its working plane.

What are the consequences of the cliff?

As it was agreed, no problems with the Lada Granta engine in the 8 valve version, if the belt drive breaks, does not arise only in the 11183-50 version of the unit. The rest of the engines are at risk of failure in the event of an unpleasant incident indicated.
In view of this, a dispute unfolded among Grantavodov over the advantages of LADA Granta engines with 16 and 8 valves, and which unit has more of them. Your point of view will also be very interesting.

In the event of a break in the belt drive, the camshaft stops in a position corresponding directly to the moment of breakdown. In contrast, the crankshaft is subject to continued rotation. This causes the pistons to hit the valves that were in the open position at a given moment. Further, the latter is bent, but sometimes a breakdown of the piston crown occurs. In the popular way "fist of friendship"!

It is based on this fact that experts are inclined to recommend changing the timing kit of the required period of action previously declared by the manufacturer.

conclusions

Now you know how long it takes to change the timing belt. Undoubtedly, a broken LADA Granta belt is a source of unprecedented problems. This circumstance does not mean that one should be inactive. Below are some recommendations, whose goal is to minimize the indicated risk.

1. Be very careful when checking the belt for wear. This action is recommended to be carried out after 10-15 thousand km.

2. Do not neglect checking the condition of the oil seals. The defect manifests itself in the form of characteristic stains under the underside of the vehicle.

3. The blinking of the lamp registering the oil pressure in the LADA Granta engine may indicate a problem. If this fact manifests itself, we urgently turn off the engine and take measures to find the source of the breakdown.

4. Use only original spare parts, although the procedure for monitoring their condition has not been canceled.

Replacing the timing belt Lada Granta 8 valves is required every 75 thousand kilometers. If you ignore the planned replacement of the belt, tension roller and sometimes the pump (coolant pump), then you can run into a serious repair of the Lada Granta engine. After all, a break in the timing belt almost always leads to damage to valves, valve seats and even pistons. Therefore, the timing drive must be treated very carefully. Once 15 thousand, it is imperative to inspect the belt for breaks, cracks, delamination or oiling.

The advice applies to VAZ-, 11186 and 21116 engines. All of them are 8-valve and are installed in Grant cars. Consider the replacement steps.

First, remember a simple rule: the 11183 engine cannot bend its valves, so you can rotate the crankshaft and the camshaft pulley separately. For motors 11186 and 21116, this would be unacceptable!

Detailed diagram of the timing drive Lada Granta

1 - toothed pulley of the crankshaft 2 - toothed pulley of the coolant pump 3 - tension roller 4 - rear protective cover 5 - toothed camshaft pulley 6 - timing belt A- lid on the rear protective cover V- mark on the camshaft pulley WITH- mark on the cover of the oil pump D- mark on the crankshaft pulley. Before carrying out any work, disconnect the battery terminal (key for 10), as well as the DPKV sensor. But first you need to remove the protective cover.

To remove protection you need: 11186/21116 - using the "internal hex by 5", unscrew 4 bolts on the upper part, which is then removed. And the bottom part is also dismantled; 11183 - use a 10-point wrench to unscrew the 3 fastening bolts. Coping with what was said above will not be difficult.

The crankshaft position sensor (DPKV) is disconnected from the connector (see photo). Then the fastening screw is unscrewed with a 10 key. The sensor itself must be dismantled.

Installation of all shafts by marks

First check that the gear is in neutral. There is a rubber cover on the crankcase housing closer to the clutch assembly. It needs to be removed.

The point is to achieve alignment of the marks on the flywheel and in the scale slot. When this is done, the flywheel is fixed with a screwdriver.

Of course, such an operation is easier to perform together. Be aware that the alignment of marks A-B and C-D corresponds to the desired shaft position (see fig.).

The crankshaft itself must be rotated to the right using the "17" or "19" key (motor 11183). The meaning of what was said is illustrated in the photo.

The alternator belt must be removed. The generator belt closes access to the timing drive parts. You will have to loosen the fastener and remove this belt.

With a key "13" loosen the lower mounting bolt. Then unscrew the top fixing nut and remove the bolt. The generator casing is pressed against the engine and the structure is fixed with wire. The belt can now be removed. The installation of the generator belt is carried out in the following sequence: 1 ... Fix the generator; 2 ... Throw the belt over the pulleys, as shown in the photo;

3 ... Having turned on the 5th gear, they roll the car back.

Be aware that reusing the alternator belt is a last resort. Better to buy a new part.

Replacing the timing belt

Let the engine flywheel be correctly installed and secured (see above). Then, using the key "17" or "19" (ICE 11183), unscrew the screw holding the generator drive pulley. The pulley itself and the protective washer are then removed.

The pulley should not interfere

Now you need to weaken the downforce in the tension roller: 11186/21116 - using the "round" key "15", unscrew the mounting bolt by 2-3 turns. The roller will "release" the belt automatically;

Automation will work on weakening

11183 - using the “17” wrench you need to loosen the fastening nut. Then the roller itself is rotated clockwise. It remains to perform a replacement: a new part is installed in place of the old timing belt, and that's it. Installation of the remaining parts is carried out in the reverse order.

Basic replacement operation

To increase the downforce, the outer roller assembly is rotated counterclockwise. For 11186/21116 motors, an additional requirement must be fulfilled: the two rectangular marks must match.

Mandatory requirement for motors 11186/21116

When editing is complete, marks A-B and C-D must also match. The drawing for them is given above.

Tightening torques

To carry out the installation correctly, you need a wrench with a force regulator. The value on it is set depending on the type of part: Tension roller fastening screw (11186/21116) - 17-27 N * m; Roller fastening nut (11183) - 30–36 N * m; Alternator pulley fasteners - 105-110 N * m. First, the tension is set on the roller, and then the fastening nut or bolt is tightened. Details from the VAZ catalog Let's immediately consider the list of units and special tools VAZ: Tension roller for internal combustion engine 11183 - 2108-1006120, nut for it - 00001-0021647-21; Timing belt (11183) - 2108-1006040-10; Automatic tension roller - 21116-1006226; Timing belt (11186/21116) - 21116-1006040; Auto roller key - 67.7812.9573-01; The key for the VAZ-11183 roller - 67.7834.9525. The tensioner roller of the 2108 family has two slots on one side. These slots should point "up", that is, away from the engine.

The slots were made for special tools. It is designated by the numbers "67.7834.9525" (see the list). And for automatic rollers, the key is designated differently - "67.7812.9573". How it looks is shown below.

The automatic roller can also be adjusted
