Chain tensioner VAZ 2106 shoe replacement device instructions with photos and videos

Timing chain tension

If a loud knocking and grinding noise begins to be heard from under the hood of a VAZ 2106 when starting the engine, the most likely reason for this is a failure of the timing chain tensioner shoe.
As a result, the chain sags and begins to hit the cylinder block cover. The tensioner shoe should be replaced promptly. Otherwise, the timing chain may break and the engine will be seriously damaged. The tension shoe is designed to reduce the amplitude of timing chain vibrations when starting the engine. If these vibrations are not suppressed in a timely manner, the crankshaft and timing shaft, connected by the timing chain, will rotate in different phases. As a result, the synchronous operation of the cylinders will be disrupted. This, in turn, will lead to failures in engine operation and its inadequate response to pressing the accelerator pedal, as well as to a sharp increase in fuel consumption.

The timing chain tensioning system of the VAZ 2106 consists of three elements:

• timing chain tensioner shoe;
• tensioner oil fitting;
• timing chain damper.

Each of these elements has its own purpose.

1. The timing chain tensioner shoe is a curved steel plate that periodically puts pressure on the timing chain and reduces the amplitude of its vibrations. The surface of the shoe in contact with the chain is coated with a particularly durable polymer material. This material is quite durable, but when it wears out, loud knocking noises from the chain beating against the cylinder block begin to be heard from under the hood.
2. The tensioner oil fitting is the device that the shoe is attached to. Because of this fitting, the shoe extends and puts pressure on the timing chain if it becomes loose, and retracts when the chain is tightened. A high pressure oil line with an oil pressure sensor is connected to the fitting. If the chain slackens when starting the engine, the sensor detects a decrease in pressure in the line. This reduction is compensated by the supply of an additional portion of oil, which puts pressure on the piston in the fitting. As a result, the shoe extends and dampens chain vibration.

First, a mechanical system was developed in which the tension shoe was driven by the elastic force of a conventional spring. Since the springs with shoes pressed continuously on the chain, such a system quickly wore out.

The mechanical one has been replaced by a hydraulic calming system, which is used on the VAZ 2106. Here, the movement of the shoe is ensured by a special hydraulic fitting, into which oil is supplied as needed. Such a system lasts much longer, and the driver has noticeably fewer problems with its maintenance.

To replace the fitting and tension shoe you will need:

• a new tension shoe for the VAZ 2106 (costs about 300 rubles);
• set of socket wrenches;
• ratchet;
• set of open-end wrenches;
• steel wire with a diameter of 2 mm and a length of 35 cm;
• flat blade screwdriver.

Before starting work, it is necessary to remove the air filter - without dismantling it it is impossible to get to the tensioner shoe. The work is performed in the following order.

Use a 14mm socket to unscrew the five air filter mounting bolts. The filter is removed.

To tension the VAZ 2106 timing chain you will need:

• set of open-end wrenches;
• flat screwdriver;
• socket wrench 19.

Procedure

The VAZ 2106 timing chain is tensioned as follows.

1. Using the above algorithm, the air filter, fitting and tensioner shoe are removed.
2. A 19 mm spanner is put on the crankshaft nut.
3. Using a wrench, the shaft is turned clockwise until the chain tension under and above the crankshaft is the same. The tension level is checked manually. To fully tension the chain, the crankshaft must make at least two full revolutions.

Video “Chain Knocking on a Classic”

This video examines the cause of engine knocking and demonstrates chain drive tension.

A VAZ 2107 timing chain tensioner is installed on the front right side of the car engine. The main purpose of such a mechanism is to tension the chain, which in turn is extended during operation.

Replacement work is not difficult and is completed within a short period of time. To replace the tensioner you must:

1. Open the hood of the car and in the engine compartment, use a ten-point socket wrench to unscrew the two bolts securing the tensioner to the cylinder block and carefully remove it. A sealing gasket will be installed between the tensioner and the block. Check its condition and, if necessary, replace it with a new one.
2. Having removed the tensioner body, we clamp it in a vice and use a thirteen key to unscrew the central cap nut, thereby checking the serviceability of the collet lock. If a crack is detected, it is necessary to replace the cap or the tensioner itself.

After checking the tensioner and if it needed to be replaced, you can begin installation. Before installing it, the tensioner must be charged; to do this, push the plunger all the way in and, holding it in this state, tighten the cap nut.

I tighten the cap nut, install the tensioner in its place and tighten the bolts that secure it. Then we turn the crankshaft one turn, thereby tightening the camshaft drive chain, after which we release the cap nut, releasing the tensioner, and tighten it again. At this point, the repair work to replace the timing chain tensioner of the VAZ 2107 is completed.

Sometimes a car enthusiast encounters extraneous sounds that come from the area of ​​the front engine cover and resemble a kind of tapping. This may be a sign that the chain guide needs to be replaced. The damper on the VAZ 2107 model is necessary to soften the vibrations of the chain during its rotation. If you can clearly hear a clattering or metallic tapping sound, this means that the damper is very worn and needs to be urgently replaced. Another possible cause of the problem is that the chain tension is too loose. In this car model, the damper is located on the left, in front of the cylinder block. Use the diagram supplied with the machine to determine the exact location of the part to be replaced.

Replacing a chain guide on a VAZ 2107 is not a complicated procedure. Each driver will be able to carry out such an operation independently if he takes into account several important points. When replacing a part yourself, you need to proceed like this.

The long fastening bolt is installed at the top, and the short one at the bottom. If the bolts have a significant degree of wear, they need to be replaced, otherwise even after replacing the damper, the characteristic tapping sound may remain.

If the damper simply breaks into pieces while moving, you need to remove all its components. Sometimes this is quite difficult to do and you have to invent various devices to get the debris out. In such a situation, a magnet attached to the end of a long wire can help out. Place all the removed parts together to determine if there is anything left inside.

Required tools:

1. keys from the standard set;
2. universal pulley clamp;
3. special key for “36”;
4. empty, clean container for draining antifreeze.

• Reassemble in reverse order and add antifreeze.
• At this point, the replacement of the timing chain on the VAZ 2106 can be considered complete.

Replacing the timing chain on a VAZ 2106, as well as a damper, tensioner shoe, and sprockets

Replacing a timing chain on a VAZ 2106, like replacing a timing belt on a VAZ 2110, is a responsible and not easy procedure that requires certain skills and knowledge. Without a basic understanding of what it is, I would not recommend taking on such work.

In addition to the timing chain, we will also replace the tensioner shoe, alternator belt, damper and sprockets. Before you start, prepare your tools; you will need a standard set of keys, as well as a universal pulley lock, a special key for “36”, and an empty container for draining antifreeze.

Instructions for disassembling the mechanism

The first thing to do is remove the engine valve cover. Here you can see some signs of wear, for example, a chain dangling on the camshaft gear or a torn damper (or rather, its absence). It even happens that in the place where it stood, the chain selected a groove in the material of the head itself. For convenience, it is better to immediately align the round mark on the camshaft drive gear with the protrusion on its bed.

This is done by rotating the crankshaft with a 38mm wrench. For further disassembly, it is better to remove the radiator, first draining the antifreeze from it. There are craftsmen who replace the VAZ 2106 chain without removing the radiator, but this makes access to the timing mechanism very difficult, which will take up extra time. It is better to spend it on dismantling and installing the radiator, creating conditions for normal operation.

Once access to the front of the engine is open, you need to loosen and remove the generator drive belt. Then, using a 38mm wrench, loosen the pulley nut in this way: engage 4th gear, and ask an assistant to press the brake, and then unscrew the ratchet. This method will save you from the need to insert various pieces of hardware into the engine to stop the rotation of the crankshaft. Further disassembly is carried out according to this scheme.

1. Remove the pulley from the crankshaft, clean the turnkey bolts on the 10th front cover of the cylinder block from dirt, and unscrew them. Three of them are located at the bottom and connect the cover to the oil pan. Remove it, clean off any remaining gasket, as well as the mating flange on the cylinder block.

Replacing the timing chain of a VAZ 2106

1. Unlock the bolts of the two gears, loosen them and unscrew them. Remove these gears, then use a 10mm wrench to unscrew the travel stop (located to the left of the crankshaft axis), and then remove the old chain. The crankshaft gear is removed last; be careful not to lose the key.
2. Use a 13mm wrench to loosen the chain tensioner nut, use a pry bar to gently press the chain tensioner shoe so that the plunger goes in, and then tighten the nut again. This is done because previously the chain tension was greater; the tensioner will not allow you to install a new one.
3. Replacing the chain tensioner consists of unscrewing its working part (shoe) and replacing it with a new one, which is done in the next step.
4. The chain damper is replaced in the same way. You need to unscrew 2 bolts with a 10mm wrench, remove the old element, and install a new one in its place and screw it on.

This photo report shows how to replace the timing chain of VAZ 2106, 2107 cars. Also, this method is suitable for all VAZ (Classic) car models, except for the VAZ 2105 engine, since it uses a belt drive.

To drive the VAZ 2106/2107, a double-row roller chain is used. It transmits force from a sprocket mounted on the crankshaft to another sprocket mounted on the end of the camshaft.

The chain is a structure that develops large inertia, so a chain drive requires vibration damping.

Even a well-tensioned chain retains the property of “playing” in those places where there are no sprockets or tensioners.

The chain has virtually zero ability to stretch and compress, and fairly limited flexibility. Therefore, in order to provide it with constant tension while working in its place at any speed, it has to be literally shackled, using a system of tensioners and dampers.

This problem on the VAZ 2106/2107 is solved by a damper - an additional spring-loaded clamping bar. They have a steel frame covered with a layer of durable rubber. Tensioners and dampers dampen vibration and noise quite effectively. The chain is prevented from falling off by a stop pin that is screwed into the block or cylinder head. During normal operation the chain does not touch it.

The performance and durability of the timing chain drive depends on the material and quality of heat treatment of the chain and sprockets themselves. Manufacturing accuracy and cleanliness of working surfaces are of great importance. The main advantage of a timing chain drive is its long service life.

On engines of the VAZ family, the chain life is from 100 to 200 thousand kilometers. If high-quality materials were used in the manufacture of components, and proper tension and abundant lubrication of the drive were ensured during operation, then the chain will last no less than the engine itself. A broken circuit is a rare occurrence.

The deterioration of its condition can be monitored by increased noise when the engine is running.

For engines 2101 and 21011, where the block is lower, the number of chain links is 114, and for 2103/2106 the number of links is 116.

Replacing the timing chain on a VAZ is necessary when its critical wear has occurred, its service life has been exhausted, and tightening it with all sorts of “cunning” methods no longer gives results. These methods include:

• increasing the length of the working part of the tensioner by pressing on a piece of tube of a suitable diameter;
• “addition” of an additional bracket to the shoe and other “bullying” of the engine.

An extended timing chain no longer ensures accurate valve timing, which negatively affects engine performance.

In addition, she wears out the shoe and constantly “beats the head off” the pacifier. In addition, engine noise increases, fuel consumption increases and engine starting becomes worse.

It is also worth saying that the chain sometimes breaks with all that it entails.

• To remove the timing chain, you do not need to remove the crankshaft sprocket!
• For work we will need: keys “10”, “13”, “17”, a special wrench for the crankshaft pulley nut (or a “36” head), a screwdriver, a mounting blade, a hammer, and a bit.
• After removing the sprocket, do not turn the drive shaft, because this may disrupt the initial ignition setting!
• The original timing chain number is 2103-1006040, the average price is 380 rubles.
• Analogues:

• Fenox PC2103C3 — 519 rub.
• Kraft KT 017736 — 620 rub.

The original number of the timing chain tensioner is 2101-1006060, the average price is 364 rubles.

Analogues:

• TSN 671 — 254 rub.
• Riginal RG2101-1006060 — 230 rub.
• Trialli MT 151 — 407 rub.

Replacement frequency: every 200 thousand km.

First, remove the block head cover.

Now we turn the crankshaft until the mark on the camshaft sprocket aligns with the mark on the housing.

The mark on the crankshaft will also need to line up with the mark on the camshaft cover.

Next, bend the lock washer of the camshaft sprocket bolt. Then we engage fourth gear and put the car on the handbrake.

Then loosen the camshaft sprocket bolt.

Using a 10mm spanner, unscrew the two nuts of the studs connecting the parts of the casing. Using a 10mm socket with an extension, unscrew the bolt securing the upper casing to the bracket. We remove the casing. Using the “10” wrench, unscrew the “propeller”.

Using a 10mm wrench, unscrew the three nuts and six bolts securing the camshaft drive cover to the cylinder block.

Remove the camshaft drive cover.

Using a 17mm wrench, unscrew the bolt securing the tensioner shoe...

Using a chisel, bend the edge of the lock washer on the oil pump drive sprocket bolt.

Using a 17mm wrench, unscrew the bolt securing the oil pump drive sprocket.

We remove the star. We take out the camshaft drive chain. Then, lifting the chain, remove the camshaft sprocket.

Using a 10mm wrench, unscrew the chain limiting pin and remove it.

Before installing the chain, align the mark on the crankshaft sprocket with the mark on the cylinder block.

Using a 13mm socket, loosen the cap nut of the chain tensioner. Turn the crankshaft clockwise one and a half to two turns. In this case, the tensioner spring, acting on the tensioner shoe, will automatically adjust the chain tension. Tighten the tensioner cap nut.

Why is the device replaced?

With prolonged use, the VAZ 2107 chain tensioner weakens (the spring loses its elasticity), which leads to improper operation of the device. This has a negative impact on the operation of the engine, since the valve timing gradually shifts, which contributes to increased heating and wear of the cylinder-piston group parts.

If it is no longer possible to tension the chain, then it may be time to replace the chain itself or one or both shoes, but perhaps only the VAZ 2107 chain tensioner has become unusable and you can only get by by replacing it, without expensive repairs. In the material we will consider the question of how to replace the chain tensioner on a VAZ 2107 car without affecting the tensioner shoe.

What is required for the work

To replace the tensioner on a VAZ 2107, you will need to use simple tools:

• Open-end wrenches for “10” and “13”.
• Key for turning the crankshaft.

After making sure that the above tools are available, you can begin work.

How much does a new product cost?

For the VAZ 2107, a tensioner from classic VAZ models is suitable, so you can choose any one that is available on the market. The average cost of this device is 600-700 rubles. Experienced drivers recommend giving preference to devices from the Tolyatti Automobile Plant, which are supplied in blue packaging. The package contains the packer's number, as well as a special sticker with a code underneath. If you send this code to the number, you will receive an SMS message with confirmation.

It is important to know! Purchase products only from certified stores to avoid purchasing counterfeits.

The Pilot brand device is also receiving positive reviews. It has its advantages compared to the standard one, and at the same time it is considered maintenance-free and more reliable. Below is the packaging of the ANC “Pilot”.

Once the Pilot or standard chain tensioner has been purchased, you can proceed to the replacement procedure. The advantage of the “Pilot” is the fact that it is an automatic chain tensioner for the VAZ 2107, which independently regulates and maintains the degree of chain tension on the seven.

Product replacement principle

To replace a worn chain tensioner on a VAZ 2107 with a new one, you will need to perform the following steps:

1. The battery is removed from the car to provide access to the element being removed.
2. The device is located on the right side of the front of the engine. Using a “10” wrench, you need to unscrew the 2 nuts securing the device.
3. In the next step, we remove the device from the engine with our hands.
4. We take a new tensioner, loosen the cover nut with a wrench to “13”, then press the protruding plunger into the tensioner itself until it stops, and tighten the same nut. To make this procedure easier, you can use a vice. This must be done to facilitate installation of the device into the engine.
5. Once the device is installed, it can be installed in place, not forgetting about the gasket. We fasten the product using fastening nuts. The device is discharged; to do this, release the cap nut. At the same time, the plunger will become free and shoot, thereby causing a tight fit of the shoe to the chain.
6. Using a 36-38 wrench or a pipe wrench, you need to turn the crankshaft clockwise 1.5-2 turns. At the moment of greatest resistance during rotation, we stop. It is important to ensure that the crankshaft remains in this position and does not move a millimeter against the stroke, otherwise the chain will sag.
7. After this, you will need to tighten the cap nut tightly to “13”.

8. Finally, start the engine and listen.

Repair of the tensioner on Lada cars is usually not carried out, so if it stops tensioning, it needs to be replaced. You can see the process of replacing the device in question in more detail in the video above.

In order to change an automatic tensioner, on average you need 600-700 rubles. TZA (Togliatti Automotive Units Plant) produces the best, “native” tensioners for “classics”. The package (blue) has the packer's number as well as an authentication sticker with a protective layer. Under the layer there is a code, when entered, you will receive an SMS confirmation. Inside there must be an insert - a form with the name of the product, the date of manufacture, and the blue original seals of the quality control department.

First, remove the cylinder head cover. This will be required in order to correctly determine the chain tension at the very end.

1. Remove the air filter housing from the carburetor. Then we disconnect the throttle linkage from the roller.
2. Then you need to remove the lever with rods.
3. And finally, we disconnect the fuel hose from the bracket that goes from the fuel pump to the carburetor.
4. Using a 10 mm tubular wrench, remove the cylinder head cover. This must be done so that you can check the chain tension by hand.
5. The VAZ 2107 timing chain tensioner is located on the right front side of the engine. First, using a 10mm wrench, unscrew the tensioner mounting nuts.
6. We take it out of the engine. There should be a gasket between the engine housing and the tensioner. Try not to damage or lose it, since a new gasket is almost always sold only complete with the tensioner. Sometimes it can start to “etch”, and in order not to purchase a kit to replace it, save the old gasket.
7. We fix the new automatic tensioner vertically in a bench vice. Then use a 13 mm wrench to loosen the cap nut. After this, the plunger became movable and moves freely in the tensioner body.
8. Now we “charge” the tensioner plunger. To do this, we place it vertically (the place where we place it is shown by a blue triangle). Then press vertically downwards with force (pressure points are shown in red). The plunger is “recessed” into the body.
9. Now you need to continue pressing on the body and holding the plunger “cocked” and tighten the nut back with a 13 mm open-end wrench.
10. Now we install the “cocked tensioner” together with the gasket into the engine housing. Using an open-end wrench 36-38 (the VAZ 2107 may have either a nut or a ratchet, so the sizes are different), turn the crankshaft clockwise by an average of one and a half to two turns. When the greatest resistance to movement arises, then the chain will be stretched to its maximum. The main thing is to ensure that the crankshaft does not turn back due to compression and that the chain tension does not weaken. If you don’t have a key for 38, you can turn on the ignition and turn the crankshaft with the starter.
11. We tighten the nut back, holding the crankshaft from “shock absorption” back. Then we check the tension result by pressing the chain with our hand again. There should be no deflection. Now we install the block head cover in place.
12. Only after the chain is tensioned should you loosen the tensioner cap nut. The plunger will release and "shoot", causing the shoe to seal tightly against the chain. At this time, a click will be heard. Only after a click does the tensioner cap nut need to be tightened tightly.

Installing the VAZ 2106 timing chain by marks

The timing chain drive of the VAZ 2106 lasts quite a long time, but there comes a time when the noise of the drive turns into knocking, and another attempt to tighten the chain leads to nothing. If there is a continuous knocking sound in the front part of the engine, the mileage of which is more than 50 thousand km, the timing chain needs to be replaced.

Replacing the timing chain

Preparing for work

Usually, during such a long mileage for a classic engine, not only the chain itself is subject to wear, but also other elements associated with it.

The process of such a replacement is simple, but labor-intensive, since you need to unscrew a lot of bolts and nuts, remove some components and parts, and this takes time.

Therefore, it is recommended to change the VAZ 06 timing kit, which includes the following main and additional parts:

• new timing chain;
• gears - 3 pcs.;
• chain tensioner shoe;
• chain damper;
• front crankshaft oil seal;
• cylinder block front cover gasket;
• crankshaft pulley key.

Very often, when removing the crankshaft gear, the key falls out and is lost, especially if there is debris or just an earthen floor at the bottom of the inspection hole. Without this part, gear installation and assembly are impossible, and given that it is cheap, it is better to purchase it in reserve.

To work you will need an inspection hole and a set of tools and keys. You definitely need a 38 mm wrench or socket, which will have to be used to unscrew the ratchet. If there is no inspection ditch, the operation can be performed without it, but for convenience it is better to remove the car hood by unscrewing the 4 bolts with a 13 mm wrench.

How to replace the chain tensioner shoe on a VAZ 2106

The tensioner shoe lining wears out during operation, and when it ceases to perform its functions, it must be replaced.
Prepare keys for ten, thirteen and seventeen for this work. Replacing the shoe itself will not take much time; much more of it will have to be spent on preparatory disassembly of the engine. To replace the chain tensioner shoe, prepare keys for ten, thirteen and seventeen, a wrench for unscrewing the crankshaft pulley nut, a flat-blade screwdriver and a mounting spatula.

1. For ease of operation, remove the engine splash guard.

2. Then remove the alternator belt by first loosening its tension, then prying it up with a pry bar and turning the crankshaft slightly.
3. The next step is to remove the crankshaft pulley. To do this, unscrew its nut with a special wrench and, using a pry bar, remove it.
4. From the bottom of the car, preferably with a socket wrench, completely unscrew and remove the three bolts that secure the end of the oil pan to the camshaft drive cover. You can loosen two or three oil sump mounting bolts that are located nearby.
5. Now you can use a ten key to unscrew the bolts and nuts securing the drive cover. There are six bolts that need to be unscrewed, and three nuts.

6. Using a screwdriver, separate the cover and remove it along with the gasket.
7. We have come to the end of the operation - you can unscrew the bolt and remove the shoe.

Here's what they look like:

When replacing a shoe, remember that they all have individual markings, which are printed on the side and indicated by an arrow in the picture. When buying a new one, make sure that it has the same one. When reassembling, follow the reverse sequence of disassembly operations, tension the camshaft drive chain, and do not forget to adjust the tension of the generator drive belt.

Operation, maintenance, replacement and repair of the chain tensioner in a VAZ 2106 car

The camshaft drive mechanism on the “six” operates using a chain-type transmission. However, the device is imperfect and requires periodic tightening. The required degree of tension is achieved with the help of a tensioner, which, with its front protrusion, rests against the VAZ 2106 chain tensioner shoe, which creates the necessary conditions for this.

You need to know that the chain tensioner is a component of the gas distribution mechanism of a car, which is constantly exposed to friction, which negatively affects the degree of wear of the associated parts. As a result, such a VAZ 2106 timing chain tensioner should be made only from high-quality materials, which are used mainly in factory production.

Of course, the price of the “six” chain tensioner, which is used during factory assembly, is slightly higher than analogues offered for sale by auto parts stores, but you should know that here the experiment with replacing the part with a cheaper one is very dangerous, and calls into question the reliability of the gas distribution mechanism in in general.

At the same time, you can see how the chain tensioner shoe and other components of this unit work. If the product cannot provide the correct tension of the chain drive when changing the position of the cap-shaped nut or does not function as a chain clamp in a tensioned position, it must be repaired, and if this is not possible, replaced.

CHAIN ​​DRIVE VAZ 2107

The chain drive on VAZ cars is designed to transmit movement from the crankshaft to the camshaft. The rotating camshaft opens and closes the valves with cams, through which the cylinders are filled with the fuel mixture, and the working cycle occurs in them. Malfunctions in the gas distribution system lead to malfunctions or to a complete stop of the internal combustion engine. Therefore, the chain drive must be maintained in good condition and adjusted if necessary.

DEVICE

The timing device of the VAZ 2107 is quite simple; there is nothing superfluous in the mechanism. The gas distribution mechanism of VAZ classic engines with a chain drive contains the following parts:

• Intake and exhaust valves on the cylinder head;
• Rocker;
• Camshaft;
• Intermediate shaft gear (sprocket);
• Intermediate shaft;
• Metal gear (sprocket) of the camshaft;
• Valve train chain;
• Tensioner;
• Tranquilizer;
• Tensioner “shoe” (lower damper);
• Crankshaft gear.

The crankshaft and camshaft are installed relative to each other in a certain position. For precise installation, there are special marks on the crankshaft pulley and camshaft sprocket. Incorrect installation, at best, leads to unstable operation of the internal combustion engine, in the worst case, the valves in the cylinder head bend, and serious repairs are already inevitable.

TENSIONER

The chain tensioner plays a very important role in the gas distribution mechanism - it keeps the chain taut. On classic VAZ models there are three types of tensioners:

• Standard mechanical;
• Auto;
• Hydraulic tensioner.

The hydraulic tensioner is standardly installed on the Chevrolet Niva and Niva VAZ 21214. But in order to install it on the VAZ 2107, it is necessary to convert the timing belt to “hydraulics”, especially since such a device is quite capricious on the “Classic”.

A standard tensioner consists of the following elements:

• Cylindrical body;
• Two springs;
• Plunger;
• Rod;
• Rusk;
• Cap fixing nut.

Standard tensioners can be from different manufacturers; the price of parts ranges from 250 to 450 rubles; the most expensive and reliable parts are those produced by AvtoVAZ and TZA. But in general, the reliability of these tensioners is quite low - they often fail.

The VAZ 2107 automatic chain tensioner is installed instead of the standard one. It is more reliable, since its design does not contain a mechanical plunger mechanism with a clamp, which causes a lot of trouble for owners of classic VAZs. In an automatic device, the chain is tensioned by a rack plunger. The retractable chain tensioner is securely fixed and does not compress under the shock load of the chain. This type of tensioner appeared on the market relatively recently, but has already proven itself on the positive side.

Typical chain tensioner defects

Such malfunctions include:

1. A collet-type clamp is not able to fix the product rod, which interferes with adjustment work on the correct tension of the chain drive.
2. Wear of the main spring element (looks like this: the spring element is deformed in one plane, which becomes noticeable after dismantling the chain tensioner, which shines on one side).
3. Damper spring failure.
4. Limit wear of the product rod at the point where the collet-type clamp is attached.
5. Defects in threaded connections on the installation fasteners (studs) of the product.

Symptoms of mechanism malfunction

The first signs that the engine chain tensioner or the chain itself is faulty are:

• A sudden stop in the vehicle's movement while the engine is running, and a significant increase in the speed of rotation of the crankshaft, with the same throttle position.
• Instant engine blocking (wedge), accompanied by a characteristic sound.

The causes of such breakdowns can also be factory defects, such as:

• A weak collet-type clamp that cannot lock the rod in one position, preventing the tensioner from working correctly.
• Deformed shape of one of the planes of the product.
• Damper spring faulty.
• Defective threaded connections of installation fasteners.

Automatic chain tensioner

Recently, as an alternative, an automatic chain tensioner has been used in the gas distribution mechanisms of such vehicles, which operates according to the following principle. The hydraulics of the system operate under the pressure of the motor lubrication and help to maintain the required tension mode of the chain drives in the required position, at which the need to manually install the VAZ 2106 chain tensioner practically disappears.

In the body of the chain tensioner, the price of which is slightly more expensive, there is an oil hole, coaxially located with the analogue in the power plant block. In the internal cavity of the body part of the product there is an adapter device with a ball, which is under high pressure, regulated by a pressure-reducing valve.

Replacing the tensioner

This element is necessary for tensioning the VAZ-2106 chain. Replacing it is very simple, just follow these steps:

1. Remove the old tensioner; to do this, unscrew the two nuts that secure it.
2. Unscrew the cap-type nut - this can be done conveniently using a vice.
3. Clamp the tensioner in a vice and unscrew the nut. Inspect the collet located inside the nut.
4. If this clamp has no defects, you can assemble the mechanism and “charge” it. To do this, you need to push the plunger inside the body, and then tighten the nut.

Timing chain tension for VAZ 2106

One of the main reasons for the occurrence of malfunctions in the tensioner unit is considered to be the characteristic knock of the chain drive from the front section of the over-valve casing, where the VAZ 2106 chain tensioner sprocket is located, mounted on the camshaft axis. Creating a certain degree of tension in the chain drive and then installing the chain tensioner is not very difficult, even for a novice car enthusiast. So:

1. Remove the air purification filter element with the housing and the over-valve casing.
2. We begin this type of repair of the chain tensioner, for which we unscrew the tensioner not completely, video instructions for dismantling which are on the Internet.
3. Using the starter handle or another method, we make 2-3 circular rotations of the crankshaft, after which the chain drive is engaged.
4. We check the tension of the chain drive by pressing on its links.
5. If the timing chain has received sufficient tension, you need to tighten the timing chain tensioner tightly and reassemble the attachment in the reverse order.

Symptoms of loose chain tension

In principle, the symptoms are quite specific, and it is very, very difficult to confuse them with something else.

• Increased engine noise, even at idle speed;
• Instant increase in noise during a sharp increase in speed;
• The roar increases proportionally with a smooth increase in speed, and decreases gradually with a sharp release of the gas pedal;
• Most often, a loose VAZ 2107 chain rattles because the damper has broken and needs to be replaced.

However, let’s say that this is not the case, and we just need some tension. To work, we will need a special key to turn the crankshaft; on carburetor cars, you can turn it using a ratchet.
