How to install a tension roller on a grant

Lada Granta cars, like other vehicles, are equipped with a generator designed to power electrical equipment components while driving. If there are malfunctions in the operation of this device, first of all the driver pays attention to the condition of the belt. Below we will talk about how to replace the alternator belt on a Lada Granta car with air conditioning.

Tensioner for Lada Granta: is it so necessary?

It so happens that the lack of an alternator belt tensioner in the basic configuration of the Lada Grant leads to the fact that the alternator on this car, according to reviews from owners, quite often fails.

The reason for this is the strong tension of the belt and the inability to adjust it properly, as a result of which the generator bearing breaks.

Many car owners come out of this situation in different ways: someone tries to reduce the diameter of the generator bolt, thereby gaining a gap in tension, someone approaches the process radically - they change the generator itself, for example, to a Bosch brand unit, and someone tries to adapt structural elements of the tensioner from cars of other brands, for example, on the belt tensioner from Lada Kalina.

The Lada Granta generator belt tensioner is really necessary, since it significantly increases the service life of the generator belt and bearing.

Replacement instructions

The procedure for replacing the RG is quite complicated and responsible. If you make a mistake during the steps, this may lead to the strap breaking while the car is moving. Of course, it will be possible to continue driving to the nearest service station or garage, but you will lose not only the money spent on the purchase of the RG, but also your own time. Therefore, think several times before whether you can do everything yourself and whether it is advisable - perhaps it makes sense to simply pay specialists at the service station. But at the same time, you will be sure that everything was done correctly, and if problems arise, you will have someone to file a claim with.

Tools and materials

So, if you decide to replace the cylinder head on an 8-valve engine yourself, below you will find instructions on how to complete this process. In order to do everything yourself, prepare the strap itself. There is one more point here - the purchase of all parts and consumables for repairing an 8- or 16-valve engine must be carried out from representatives of an official dealer. Today the cost of such a RG is around 12-15 dollars or 700-1000 rubles.

Design features of the generator belt tensioner

Such a component as the generator belt tensioner has a very simple structural design, is easy to repair, and even a not very skilled driver can install the tensioner.

It is known that each car manufacturer creates tensioners according to its own designs, but most tensioners have the following components:

— bracket for mounting on the engine;

— belt tensioner roller;

The bracket is secured to the engine using 3-4 bolts or studs. It is believed that the most vulnerable point of the tensioner is the bearing. It has been experimentally proven that the bearing, being constantly in motion and simply making a countless number of revolutions, exhausts its life and needs to be replaced.

After completing the procedure for removing the alternator belt, diagnosing the bearing is very easy. A properly functioning bearing should have no play.

The bracket can cause just as much trouble. After some time, the bracket tends to bend slightly, displacing the roller from the plane of rotation of the belt. This defect can be observed not only in cars that have a significant mileage.

Sometimes a bent alternator belt tensioner is also found on completely new cars, which casts a shadow on the shortcomings of the factory production.

The belt tensioner pulley of the Grant generator also fails. Such a defect leads to a weakening of the belt tension, which in turn can affect the operation of the generator.

It is very easy to diagnose such a problem, because it is diagnosed in the same way as the Grant timing belt tensioner pulley - you just need to loosen the tension of the roller and rotate it. Rotation must occur without difficulty and play, otherwise it will need to be replaced.

Design features of the drive of different motors

To understand how maintenance work is performed on the timing drive, let’s first consider its design.

So, the gas distribution mechanism is driven from the crankshaft. In this case, the valve timing in the engine cylinders has 4 cycles and they are performed in two full revolutions of the crankshaft.

But 2 of these cycles occur with the valves closed, so the camshaft must ensure only one closing and opening of the valves during all 4 cycles.

Therefore, for two revolutions of the crankshaft, only one revolution of the camshaft is made. Moreover, this is achieved quite simply - due to the different diameters of the drive toothed pulleys.

The belt has a toothed working surface, which prevents it from slipping on the pulleys. In addition to transmitting force from the crankshaft, the belt performs another function - it drives the cooling system pump.

In this case, the drive must be constantly tensioned to prevent the teeth from jumping on the pulleys, which is why a tension roller is included in its design.

This is the entire drive structure, that is, it includes only two toothed pulleys (crankshaft and camshaft), a pump gear, a tension roller and the belt itself.

All this is located on the side of the engine, not inside. But to prevent the ingress of dirt and technical fluids that could harm the belt, all elements are covered with protective shields.

But this describes the design of a gas distribution mechanism with 8 valves, which is driven by only one camshaft.

But some Lada Granta models are equipped with engines with a 16-valve timing mechanism and two camshafts. But because of this, the drive design does not change much.

Unlike the 8-valve, there is not one, but camshafts and, accordingly, two toothed pulleys, and another roller has been added to the design - a bypass roller, also known as a support roller. That's where all the differences ended.

We replace the belt tensioner with our own hands

The procedure for replacing the alternator belt tensioner is not difficult to carry out yourself. The only thing you need to have is a high-quality tool for installing the tensioner. The Grant generator belt tensioner is changed in the following order:

— disconnect the contacts on the battery terminals;

— then we weaken the tension force of the roller and remove the generator belt;

— unscrew the bracket nuts and remove the bracket itself;

— install a new bracket with a roller installed on it;

Symptoms of tensioner failure

Signs indicating malfunction or wear of the relevant parts:

no battery charge indicator;
a whistle or squeak in the area of the working area of the generator belt, appears when it slips in cases where the tension roller is jammed;
a hum that sounds when a bearing wears out or fails;
vibration of the belt or roller when the engine is running indicates wear of the bushing, replacement of which is inevitable;
the amount of belt deflection exceeds one and a half centimeters, which indicates the need for appropriate adjustment;
free play in the tension pulley or roller indicates that the bearing is worn out;
one side of the belt is more stretched and worn, a sign of a bend in the tensioner bracket.

What is needed to replace the Lada Granta

Tool

For work we will need:

sharp knife (remove old belt);
a longer flat-head screwdriver;
wrench to “13”;
new belt. Catalog number 1118—1041020—07, size—823 mm.

When going shopping, take the old belt with you.

Replacement instructions

The belt is replaced as follows:

We remove the defective belt.
Using a “13” wrench, loosen the bolt securing the generator from below. You need to loosen it slightly without unscrewing it all the way.
Unscrew the top mount and remove the nut and bolt.
Use extreme caution. Rotating the generator until the upper eye is exactly behind the surface of the protrusion on the bracket, we will fix them in this position with ordinary wire.
We put the belt on the generator pulley (pictured 2), and on the top of the drive pulley (pictured 1).
Having engaged fifth gear, we push the car back. We need to rotate the drive pulley so that the belt lies in its place.
We remove the wire and carefully use a screwdriver to move the generator to its original position.
We return the upper bolt and nut to their place, tighten them, then tighten the lower one.

This is how a belt is replaced on an 8-valve engine in a car without air conditioning. Then you can start the engine and load the generator to check - turn on the heating, high beams, and other devices.

The 8-valve valve is installed only on the cheapest configurations - the norm and the standard. The Lux received a 16-valve power plant. Replacing the belt on it is not much different from other models with the same motor.

Design principles

Operation of the generator and the units dependent on it: battery, electronic devices is possible only if the belt tension is normal. Each manufacturer tries to improve the components and design of the models they produce, but the principle of operation and their possible configuration are always the same. The standard components of this unit consist of the following parts:

a bracket attached to the engine block with several bolts;
tension roller with internal bearing;
roller fixing bolt.

There are a couple of simple modifications to this device:

a tension roller with an offset center, by rotating the eccentric, we achieve the required tension, which is secured with a bolt;
the roller is mounted on a movable bracket; in this version, the belt is tensioned using a corresponding bolt.

In any of these versions, the main element on which the main load is directed is the roller bearing.

Car with air conditioning: the differences are not only in the presence of a tensioner

Owners of cars with air conditioning will have to stock up on WD-40 or similar lubricant, a “10” key, and also a cylinder one, since the right front wheel will need to be removed.

We do not change the procedure, otherwise the lubricant will not have time to act.

We wet the bolts securing the cushion and bracket.
We support the front part of the car on the right with a jack.
We remove the wheel.
While lowering the car, unscrew the tension roller.

We work carefully because we only need a little engine lift.

Note that to work you will have to lower the car without the wheel.

An attempt to reduce the cost of cheap Grant configurations led to the absence of a tensioner on the alternator belt, which is why the latter can be over-tensioned and, as a result, fail.

Modification of the Lada Granta generator mount

Remaking the belt tensioner of the LADA Kalina generator

Then remove the floor tunnel lining from the left leg side of the front passenger, up to the upper surface of the block. One of the disadvantages of the 2108 8212 body is its weakness relative to the Lada Granta: replacing the alternator belt without a tensioner with the front wheels on a bulge such as a curb or a large stone. For this reason, many car enthusiasts replace them at the first opportunity, choosing more reliable parts. But you understand perfectly well that any liquid loses its properties over time.

Checking and prevention

to prevent generator belt . You should make it a rule to check the belt tension before starting your journey. It should not sag or be overtightened. When you press the belt with your finger, it should press down a little, and when you try to turn it over, it should turn onto its edge without effort.

It should not be bent, its teeth should be intact. You need to inspect the seals. Leaking oil negatively affects the wear resistance of rubber. Granta users will have to listen carefully so as not to miss the moment when the alternator belt needs to be replaced. You can determine that the alternator belt will soon break: in wet weather or on a cold engine, it begins to whistle.

If the problem begins to appear in the middle of the journey and there is no opportunity to go to a service station, you need to check the condition of the belt tension. Most likely, the belt can be tightened a little and movement can be resumed. After this, it is necessary to replace it. Additional signals regarding an impending problem will include:

dim light from headlights and dashboard;
The interior heating is unstable;
the sound of car horns has become lower;
The turn signal and windshield wiper operating intervals have increased.

What is a timing belt for?

The timing belt on a Lada Granta car is necessary to synchronize the operation of the camshaft and crankshaft. In the instructions for cars 16 and 8 cl, the replacement period is regulated. However, nevertheless, most car enthusiasts know little about it and may not even know its location, not worrying about how to change it correctly. It is easy to find; you just need to lift the hood of the car. In the most visible place there is a timing belt covering many pulleys. By opening the instructions that come with the vehicle, you can also easily find the section that describes this unit. The timing belt interacts not only with the crankshaft and the camshaft, but also with several other systems. Such a load significantly reduces the life of the belt, which makes it possible for it to break.

Solution

You can avoid regular contact with the described problem. There are several ways out for this.

Generator replacement. Suitable for those who purchased a car with a ZiT generator. Since 2013, new Grants began to be equipped with a generator from Bosch.
Replacing the bearing on the generator. This option, like the next two, threatens to void the warranty.
Reduce belt tension by thinner fastening.
Install the tensioner from Kalina.

Regarding the third point, some masters are not puzzled by finding a suitable option. They fix the standard fastening themselves, using a grinder and a sharpener to make it thinner. To implement the fourth option, contact a service station (also with loss of warranty) or perform all the manipulations yourself.

installed in the Lada Granta will not relieve the car owner from worries. In the new design, the bracket requires close attention. Its service life is limited. It is subject to deformation during operation and cannot be restored, only completely replaced.

Reviews

№	Positive
1.	Victor: I’ve been using the car for the second year, I’ve driven more than 31,000 km. The build quality is good, no complaints. I fix minor defects on my own; I don’t use service station assistance.
2.	Ivan: after 35,000 km, I heard a creak in the engine compartment, took it to the service center, and they said that the roller had fallen off. I'm on friendly terms with technology, I replaced it myself. I think that a resource of 35,000 km for domestic parts is very good.
3.	Vladlen: I’ve been driving the car for a year and a half, no complaints. The build is not bad, for a model in the budget segment. After the purchase, I immediately re-tightened all the components and connections.
4.	Ignat: my roller flew along with the belt at 32 - 33 thousand km. This is good for Lada. I didn’t change traditions and bought the original ones.
5.	Gennady: At the first maintenance, the mechanic tightened my belt, but hasn’t changed anything yet. The car is almost one year old, I bought it at a dealership.
6.	Vasily: The car is in its second year, no complaints. I strictly follow the manufacturer’s recommendations, I don’t race, my driving style is moderate.
7.	Georgy: my positive review about the quality of the original rollers, replaced them at 34,000 km. Special thanks to the store manager for recommending spare parts.
Negative
1.	Kirill: despite following the manufacturer’s recommendations, the moderate driving style of the roller flew for 20,000 km. For Granta this is very little. For example, Renault Logan lasts for at least 40,000 km.
2.	Ivan: in a year and a half of using the car, I contacted the car service for the second time. As for a car under warranty, this is often the case. I plan to sell, I have my eye on Renault Logan.
3.	Slavik: I rented the car from a dealership, drove it for a year without any problems, then it started falling apart. The build quality is very poor.

If the belt breaks on the way

When a break in the alternator belt still catches the driver in the middle of the journey, it is possible to temporarily correct the situation. If you are aware of such a problem with your car, it would be wise to carry a spare belt with you. When replacing a belt at a service station, special devices are used. But, of course, an ordinary driver cannot have these on the road. Therefore, the procedure must be carried out carefully and carefully.

We need to wait for the car to cool down. Next, remove the right side of the mudguard. Then the belt scraps are removed. After this, put on a new belt in stages, first on the crankshaft pulley, then put the other part of the belt behind the pulley, pressing it against it, and begin rotating the crankshaft clockwise. But if you don’t have a spare timing belt at hand, you can replace it with improvised materials.

Nylon women's tights are perfect. As a rule, they are sold in almost any store, even grocery stores. The advantage of this wardrobe detail is that the tights have a tension limit; you won’t be able to overtighten them. They are tied in a tight, reliable knot. After the structure is fitted, the excess is cut off as close to the knot as possible so that nothing catches anywhere.

In cases where tights don’t work out, elements from a men’s wardrobe are perfect. Leather belt of trousers or bags or a tie. In this case, the length of the future product is measured in proportion to the worn-out belt. This approach is due to the fact that leather and fabric products can be overtightened, which can cause damage to the mechanism. In this case, repairs will be much more serious than just replacing the alternator belt.

If you study the reviews on the model, it is clear that stories with the Lada tensioner are quite common. Grant's warranty period is not at all comparable to its Korean counterparts. It is only 24 months. The frequency of operation of the machine decides a lot. Taking these factors into account, everyone will be able to individually decide how to deal with the annoying nuisance: wait two years or sacrifice the node guarantee by resorting to radical actions.

Possible faults

Let's consider possible tensioner malfunctions and ways to eliminate them.

Roller wear. During its life cycle, a roller bearing makes a huge number of revolutions. Constantly moving and being under tension, he quickly breaks down. To check the condition of the bearing, you need to remove the alternator belt. A faulty bearing rotates unevenly and makes noise during operation.

Defects on the roller surface. For various brands of cars, rollers are made of plastic, steel or nylon. Their surface can be smooth or ribbed. The surface of the roller should be free of cracks, nicks and signs of wear. If such defects exist, the belt will cut into the surface of the roller and quickly wear out. To solve the problem, you need to replace the tensioner pulley.

Cracks and traces of rust. If rust drips from the tensioner, or there are streaks of rust between the arm and the base, the tensioner is damaged or its components are worn out. Most often, rust concentrates in the area of the mounting bolts and tensioner travel stops.

Worn tensioner lever. To diagnose the lever, you need to turn the tensioner full stroke, applying force to the lever with a wrench. The lever should move freely, without effort. If the lever squeaks and sticks, it needs to be replaced.

Spring weakening. If the components driven by the belt do not rotate, and the belt itself squeals as it slips, the tensioner spring is weak. For diagnostic purposes, move the tensioner lever full stroke using a wrench. If you do not have to apply any effort when moving the lever, or these efforts are minimal, it means that the spring has weakened. In this case, the tensioner should be replaced.

Tensioner block misalignment. If the mounting bracket is bent, the tensioner is not installed correctly, or there is corrosion between the base of the tensioner and the mounting surface, the belt will not sit flat on the pulley. Such misalignment can be detected using a laser level. If the misalignment cannot be corrected, the tensioner will have to be replaced.

Bracket wear. The bracket is another part that can cause the tensioner to fail. Over time, the bracket can bend and cause the roller to move out of the plane in which the belt lies. As a result, one side of the belt will stretch more than the other and the belt will wear out prematurely. If the belt is bent too much, it may come off.

If during diagnostics a bending of the bracket was detected, then you should not try to align it for two reasons. Firstly, after some time the bracket may become deformed again. Secondly, after straightening the bracket, there is no guarantee that the roller will be positioned correctly. Therefore, if wear is detected on the bracket, this part should be replaced.

ATTENTION! Bracket bending can be found even in new cars that have just come off the assembly line. Such a curvature indicates that the car has a manufacturing defect.
