Alternator belt tensioner roller Kalina 8 valves

Alternator belt tensioner Lada Kalina

The generator is used to generate electricity, which powers the entire on-board network in a moving car, including the Lada Kalina. This implies the need for uninterrupted operation of this node. The battery is also recharged through the generator set. The Lada Kalina generator is driven by a belt that requires proper tension.

Operation implies the presence of situations in which the generator belt tensioner ceases to correspond to the required optimal value. This inevitably provokes interruptions in power generation. In the modern domestic model Lada Kalina, among the most common reasons causing disturbances in this system, there is a malfunction of such a part as the generator belt tensioner (roller). It is this important element of the practical Lada Kalina that will be discussed further.

How does the tensioner work and what is the principle of its operation?

Only at a certain level of tension in the belt drive does optimal operation of the generator occur, which allows the supply voltage to be sent to the on-board network with maximum efficiency, otherwise tension is required. The generator belt tensioner we are considering is used for these purposes. Structurally, this is an ordinary bearing, the upper part of which is protected with a plastic coating. The belt moves along the working surface of this roller. The internal race of the tensioner is presented in the form of a conventional landing sleeve. Its tension must be certain.

Types of rollers according to design principle:

Eccentric type. This option is the simplest product, whose design is very ordinary and endowed with enviable reliability. The part includes a bearing, bushing and protective pad.
Bracket view. Here the adjustment process is carried out by moving the tensioner bracket present on the motor. The tensioner bracket is not difficult to find.

Signs of breakdown and vulnerable spots

In any tension roller design, the weakest point is the bearing. The part is subject to loads of a constant nature, in addition to which temperature differences contribute. Under such conditions, element failure can occur quite often.

Let's take a closer look at the list of main signs, due to the presence of which the roller can be considered faulty:

The battery no longer receives a full charge;
the car's energy-intensive current collectors began to show disturbances in their functioning;
a characteristic hum coming from the area where the generator unit is located;
presence of play during roller operation;
The working surface of the generator set drive belt shows signs of uneven wear.

Fault diagnosis methods

When checking the correct operation of the tension device in the Lada Kalina, it is recommended to follow the following algorithm of actions:

First, we carry out visual observation of the belt and the roller itself. To do this, you need to open the hood and start the LADA Kalina engine. When inspecting rotating components, we evaluate them for the presence of vibration.
We control the tension force of the belt drive. To do this, stop the engine. We take hold of the belt branch with our hand and try to rotate it 90 degrees relative to the longitudinal axis. Rotate clockwise. If this manipulation is successful, then the tension is correct. When the angle obtained as a result of turning the branch is different from the indicated optimal value, further adjustment is required.
Now you need to check the tensioner itself. To do this, you need to remove the belt. Before direct dismantling, remember the original location of the consumable element. Loosen the adjusting nut on the roller, after which the belt can be easily removed. We scroll through the video and observe the absence of jamming and noise. We inspect the protective cover and check for the presence of play. We pay special attention to the working surface, which comes into direct contact with the belt. It should be smooth, and the presence of deep ditches or other damage is unacceptable. If any of the indicated signs occur, then such a tensioner must be unconditionally replaced.

How to replace the Kalina generator roller?

Here we need the following tools:

a screwdriver with a flat tip;
keys whose standard sizes are: “8”, “19”, “17” and “13”;
awl.

Process.

How to tension the alternator belt correctly step by step:

First, by opening the hood of the LADA Kalina, we loosen the tension of the belt drive.
Now we use a wrench set to “19”, with which we loosen the tightening torque of the nut. Rotate the rod in a clockwise direction until it comes completely out of the seat.
Next, use an awl to pry up and remove the plastic protective cap present on the roller. A screwdriver with a thin and flat “tip” may be suitable for this purpose.
We find a bolt that secures the bearing to the bracket. To do this, we “arm ourselves” with the key to “17”.
Now carefully remove the roller. It comes with a protective washer and bushing.

Let's sum it up

This completes the dismantling procedure. Now you know how to tension the alternator belt. The steps for reinstallation are also very simple, so there is no particular need to comment on them. Upon completion of the entire list of installation procedures, we check the tension level for compliance with the specified requirements. We start the engine and observe the operation of the unit. If no side factors are detected, then the work was done correctly.

Also in LADA Kalina it is possible to remake the tensioning device, which is confirmed by this video:

Forced tuning

Unfortunately, since 2011, designers have abolished the tensioner on Kalina. They were guided primarily by considerations of economy, but they did this without any modification to the generator. In practice, cases of its premature failure immediately became more frequent. Therefore, owners began to install the tensioner on their cars themselves.

It's not very difficult to do this. True, you will have to purchase not only the tensioner itself, but also the generator bracket. The only problem is removing the standard belt. It is very difficult to remove because it is very tight at the factory. You can simply cut it, as you will have to buy a new one. The fact is that the Kalina generator belt without a tensioner has a size of 820 mm, but 880 will be needed.

A whistle appeared near the generator. Checking the belt tension is normal. Suspicion of the pressure roller. A more thorough inspection showed that the belt had jumped 1 groove to the right on the pulley. We loosen, rearrange, tighten - the whistle disappeared.

5000 thousand) At 38000 thousand. It started to whistle very loudly, the whistle did not disappear even after warming up. Upon inspection, it turned out that the belt had jumped one groove towards the engine on the camshaft pulley. We rearranged it, adjusted the tension, after 2000-3000 thousand. history repeats itself. The roller is also skewed. The whole dog is buried in the tension mechanism, or rather in its distortion. I'll try to level it with washers.

When replacing the alternator belt or when repairing the engine, it is imperative to check the condition of the alternator tensioner roller.

The roller should rotate easily and silently, there should be no traces of grease from the roller

To replace the roller, you need to loosen the tension on the generator drive belt.

Use a screwdriver to pry off the roller cover (shown on the removed tensioner)

Using a spanner wrench or a 17mm socket, unscrew the bolt securing the roller to the lower bracket of the tensioner (the bolt thread is left-handed, so unscrew the bolt clockwise)

For clarity, we show it on a removed tension device.

We take out the tension roller with the bolt, support sleeve and washer

Install the tension roller in reverse order

To remove the tensioner completely, release the belt tension.

Using a 13mm head, unscrew the bolt securing the upper bracket of the tensioner to the generator bracket.

Remove the washer from the bolt (located on the inside of the tensioner bracket), remove the bolt and bushing.

Using a 13" socket, unscrew the bolt securing the lower bracket of the tensioner to the generator bracket (shown on a dismantled engine for clarity).

We take out the tensioning device assembly.

We remove the bolt securing the lower bracket of the tensioner by removing the spacer and two cup washers from it.

If necessary, disassemble the generator drive belt tensioner.

Lada Kalina: alternator belt tensioner, check and replacement

As you know, the Lada Kalina generator belt (belt of attached units) gradually wears out, stretches, etc. during the operation of the car. For this reason, you should constantly check the tension of the generator belt, and also assess the condition of this element for delamination, cracks and other defects.

Symptoms of a problem

Damage to the tensioner is usually easy to diagnose. It is often noticeable visually. Running the car for a short time without an alternator belt helps to identify the problem. This often allows the damage to be localized. You should think about replacing the Kalina generator belt tensioner in the following cases:

Presence of traces of rust and corrosion on the roller axis.
A characteristic whistle when the engine is running.
Short service life of the alternator belt.
Curvature of the roller relative to the belt.

Replacing the LADA Kalina alternator belt and tensioning it yourself: size and length, when to change

The correct operation of the generator itself and the entire electrical system of the car depends on the alternator belt.
If the belt is worn out or sagging too much, there is a danger that the generator will not produce current and the battery will quickly discharge. Starting a car will be very problematic. The entire electrical system will fail. Determining whether a belt needs to be changed is quite difficult, but some signs may indicate this:

when the engine is running, the headlights become weak and dim;
extraneous noises, whistling when starting the car.;
After a mileage of 30 - 50 thousand on Kalina, it is worth checking the serviceability of the belt. It may have cracks, broken teeth, cuts, oiling or delamination of rubber, which can lead to belt breakage. In this case, it is better to replace it.

What is it needed for?

As mentioned above, any vehicle is equipped with such an important device as a generator. If it fails, the operation of the vehicle will be impossible. Therefore, special attention should be paid to the performance of all elements of the device, be it a Lada Kalina with a 16- or 8-cl. engine, with or without air conditioning. What is the component size? How is the roller strap adjusted and replaced? How to tighten up? You can find out the answers to these questions in the article.

Car Lada Kalina tuning

Before answering questions that interest Lad Kalin owners, you should understand why this component is needed. Not every motorist knows what role he plays in the functioning of the car.

In modern cars, this belt is the only element that allows you to transmit crankshaft rotation to the generator. When the crankshaft transmits rotation to the device pulley, energy appears in the vehicle's electrical network, thanks to which all electrical equipment operates.

Belt and roller selection

Several types of belts are used on Lada Kalina cars.

The type of element depends on the engine model and its equipment:

The motor version without air conditioning and tensioner has a belt length of 823 mm. Gates (number 6PK823) is standardly used, but such a part is not supplied as spare parts. To replace it, a slightly different strap is used - Gates 6PK823SF.
The version of the unit with a belt tensioner, but without air conditioning is 882-884 mm. Standard part manufactured by Gates (article 6PK882). In addition to it, straps are often used - Finwhale BP6883, Dayco 6PK888 or the cheapest Balakovo belt BRT882.
Engine with air conditioning and belt tensioner (motor 11183) - 1018 mm. Standard element manufactured by Gates (number 6PK1018). Alternative options are Dayco 6PK1018 or Continental 6PK1015.
The 21127 16-valve engine with air conditioning and tensioner uses a 995 mm belt. The Gates part (6PK995) is supplied from the factory, and it is also used as a spare.

Instructions on how to assemble a tensioner on a grant

Any Grant has space for installing a tensioner. To assemble this you will need:

generator bracket from Kalina;
tension roller and its bracket;
screw tensioner;
new belt from Kalina;
bushings and bolts.

Replacing the tension roller of the Kalina generator belt - Automaster

Operation implies the presence of situations in which the generator belt tensioner ceases to correspond to the required optimal value. This inevitably provokes interruptions in power generation.

In the modern domestic model Lada Kalina, among the most common causes of malfunctions in this system, there is a malfunction of such a part as the generator belt tensioner (roller).

It is this important element of the practical Lada Kalina that will be discussed further.

Most common faults

During operation, the surface of the roller is constantly in contact with the generator belt. In addition, it is in continuous rotation, which places additional demands on the reliability of its bearings. The tensioner bracket is also subject to heavy load. Hence the main problems:

Bearing wear. It simply runs out of service life or becomes unusable due to dust and dirt getting on it.
Damage to the work surface. As already mentioned, the roller itself is made of plastic. Despite its high wear resistance, it often cannot withstand loads. This manifests itself in the form of scratches and chips, which quickly render the alternator belt unusable.
Misalignment. This means that the belt and tensioner are at a certain angle to each other. Alignment can be disrupted in both the horizontal and vertical planes (due to the curvature of the bracket). This always causes rapid wear of the belt and the roller itself.

Often the cause of the malfunction is the driver himself. When trying to make adjustments, he forgets or does not loosen the locknut enough. As a result, the hexagon of the stud breaks off, and the Kalina generator belt tensioner fails.

We exhale, we are not in danger of bending the valves

If you have an 8-valve engine, then bending the valves and replacing them, as a rule, does not threaten you, but if the “head” is 16-valve, you are definitely guaranteed to replace these elements. However, in this article we will look at how to change the timing belt on a younger brother, when a breakdown does not entail any unpleasant consequences, and all work can be carried out almost in the field and with minimal knowledge.

Major breakdowns

There are three main types of timing belt failure:

The integrity of the belt structure is compromised - in this case, the belt delaminates, and the internal threads on its surface become visible to the naked eye. These problems occur due to mechanical damage or due to incorrect adjustment. This belt must be replaced immediately.
Over-tension or under-tension of the belt - the tension roller is responsible for the degree of belt tension, which allows the belt to rotate around its own axis and allows it to be adjusted correctly. If the belt is too tight or too loose, it will fall into an indecent state very quickly.
A break is the most unpleasant situation that can happen on the road with a timing belt. In this case, the engine will completely stall and it will be possible to start it again only by installing a new element.

To avoid such troubles, the manufacturer recommends checking it every 15,000 kilometers and replacing it every 75,000 kilometers. In fact, it should be changed as soon as visible cracks are detected on the surface.
