Replacing the Kalina generator bracket

To remove the generator from vehicles with VAZ-21126 and VAZ-21127 engines, follow these steps.

In cars with and without air conditioning, the generators are mounted differently, since a new design bracket was used to install the air conditioning compressor common with the generator, which differs significantly from the bracket of the previous design. The work is shown on the example of a car without air conditioning. Methods for removing the alternator in an air-conditioned car are specifically indicated.

You will need: keys "for 10" and "for 13".

Disconnect one cable from the negative battery plug.

Place the vehicle on a lift or jack and remove the front right

wheel

Remove the right front wheel liner

This is the location of pin A and terminal B of the D + output of the alternator of an air-conditioned car.

This is how the adjusting bolt is found in a car with air conditioning. Be sure to tighten the locknut of the adjusting bolt after completing the adjustment!

Good afternoon, dear readers. Today we will talk about the well-known problem of the Lada Granta generator. Many people think to change the generator support to Kalinovskaya, but not many know what to do. Fortunately, Alexei Venev from Kashira knows and shares his experience with us.

So, the first thing you need to do is buy a stand. And it's not easy to buy. Bought by the piece and went for 4 days. I went around 17 stores, sorted everything out, but in the end I bought everything I needed

We collect all this business according to the scheme. As a result, we have

Since the bushings could not be found, I temporarily installed two washers in their place.

The next step was to replace the alternator bearings. Disarmed.

The small bearing was removed easily, but the large one could not be removed. I unscrewed the pulley nut and tried to remove it, but it didn't work. In general, I spent more than an hour on it, hit it with a hammer, but that didn't help either

He spat on this matter, threw this generator away and went to buy the prior one. It turned out that the generator of Lada Granta and Priorovsky is the same. After that, I installed everything on the car. Everything fell like a native.

On Kalina, like on most modern cars, an alternator belt tensioner is installed. This greatly simplifies the setup and makes it possible even with minimal driving skills. But this is not its only function. Why else do you need a generator belt tensioner in Kalina? The article answers this question. Information is also provided on the tensioner, its most frequent breakdowns and its replacement.

Adjustment methods

Currently, there are three main ways to tension the alternator belt on cars:

1. With the help of a special arched bar. In this case, the generator has two attachment points. One of them is an axis around which you can move within small limits. The other is the nut on the adjusting bar. If you let go, you can move the pulley the required distance. This method is now considered obsolete. It is mainly used on classic VAZs.
2. The generator is moved by turning the adjusting bolt. Such a system has become widespread on cars of the tenth family.
3. With tensioner. This is a special movable roller that rests against the belt between the alternator pulleys and the crankshaft. It is equipped with a screw mechanism. By rotating it, you can adjust the pressure. This is the alternator belt tensioner Lada Kalina.

Tensioner advantages

What didn’t suit designers with the previous customization methods? Why add an extra video? It's not just about convenience. The tensioner significantly increases the resource of the generator. Without a roller, all the load falls on its bearings. If the belt is tensioned normally, then there is nothing to worry about. The generator in this case will serve many thousands of kilometers. However, very often car owners tighten their belts, and this is bad.

The load on the bearings increases many times, which is why they quickly fail. In itself, this is not so scary and expensive, although repairing the generator is quite laborious. But the car owner does not always recognize the breakdown in time. The bearings gradually “break”, the rotor shifts and begins to stick to the stator winding. The result is the need to purchase a new generator. Of course, the Kalina generator belt tensioner pulley may also fail, which happens quite often, but this is only 400 rubles, not twelve thousand.

Design

The main element of the tensioner is the pressure roller. It is made of plastic and a sealed bearing is pressed inside. The roller is mounted on its own support, which can be moved in a vertical plane with the help of a threaded bolt. This provides the necessary moment of pressure on the belt. To prevent spontaneous movement of the mount due to engine vibration when the vehicle is moving, the stud is tightened with a lock nut from above. The whole structure is placed on the generator support. It has two holes for attaching the Kalina generator belt tensioner.

Most common malfunctions

During operation, the surface of the roller is constantly in contact with the alternator belt. In addition, it is in constant rotation, which imposes additional requirements on the reliability of its bearings. The tensioner bracket is also under heavy load. Hence the main disadvantages:

• Bearing wear. It simply depletes the installed resource or becomes unusable due to the accumulation of dust and dirt.
• Work surface damage. As already mentioned, the roller itself is made of plastic. Despite the high wear resistance, it is often not load-bearing. This manifests itself in the form of scratches and chips, which quickly render the alternator belt unusable.
• Alignment violation. This means that the belt and tensioner are at an angle to each other. Alignment can be disturbed both in the horizontal and vertical planes (due to the curvature of the support). This is always the cause of rapid wear of the belt and the roller itself.

Often the driver himself is the cause of the malfunction. When you try to adjust, you forget or don't loosen the locknut enough. As a result, the hexagon of the stud breaks and the Kalina generator belt tensioner fails.

Symptoms of a malfunction

Towbar damage is usually easy to diagnose. This is often visible visually. Short-term operation of the car without an alternator belt helps to fix the problem. This often allows localization of damage. It is worth thinking about replacing the viburnum generator belt tensioner in the following cases:

• The presence of traces of rust and corrosion on the roller shaft.
• Characteristic hiss when the engine is running.
• Short generator belt life.
• The curvature of the roller in relation to the belt.

If the cause of the malfunction is accurately determined, you can begin to eliminate it.

Replacing the tensioner

The device consists of several elements, each of which is removable. Therefore, the need to replace the Lada Kalina generator belt tensioner assembly does not occur so often. As a rule, this is due to mechanical damage to the mount and shutter.

Replacement work should begin with the preparation of the tool. A special variety is not required, enough keys for 8, 13 and 19. Replacement is carried out in the following sequence:

1. With a 19 wrench, the tensioner locknut is unscrewed.
2. Using an 8 wrench, turn the pin clockwise. Here you need to be careful and not put too much effort. If rotation is difficult, it is better to loosen the locknut a little more.
3. The pin is released until the roller stops acting on the belt.
4. By unscrewing the two 13 screws, you can completely remove the tensioner.

Here you should pay attention to one point. The bushings are inserted into the mounting holes of the tensioner. When removed, they often fall off and are lost, and they may not be on the new tensioner. Bushings are necessarily included, but not everyone knows about their existence, so they do not check when buying. Installation of the Kalina generator belt tensioner is carried out in the reverse order. The pin is tightened with a force of 0,18 kgf/m.

Forced tuning

Unfortunately, since 2011, the designers have removed the tensioner from Kalina. At the same time, they were mainly guided by considerations of economy, but they did it without any refinement of the generator. In practice, cases of its premature failure immediately became more frequent. Therefore, the owners themselves began to install a tensioner on their cars.

It is not very difficult to do this. True, you will have to buy not only the tensioner itself, but also the generator mount. The problem is only in the normal removal of the belt. It is very difficult to remove, as it is very tight from the factory. You can just cut it, because you have to buy a new one. The fact is that the Kalina generator belt without a tensioner has a size of 820 mm, and 880 is needed.
