Which tension roller is better for viburnum

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 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.

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 supplied 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:

1. 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.
2. 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.
3. 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:

1. First, by opening the hood of the LADA Kalina, we loosen the tension of the belt drive.
2. 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.
3. 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.
4. We find a bolt that secures the bearing to the bracket. To do this, we “arm ourselves” with the key to “17”.
5. 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 completed correctly.

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

Which rollers or bearings, which belt is better for Suzuki Grand Vitara

Non-original high-quality Gates belt
There are a lot of consumables on sale for replacing original rollers and drive belts. However, they are all of different quality and at different prices. Original Suzuki belt 95141-60G90-000 (17521-77E20 for 2-liter and 17521-64J00 for 1.6-liter engines). Its length without climate control is 1545 mm, with climate control - 1645-1650 mm. There are many belts, but the following brands have earned the trust of Grand Vitara owners:

• 5PK1645, for many years at the forefront of GATES ;
• LYNXauto , analogue of the original, order number 5PK1645;
• STELLOX , article number 04-00673-SX;
• BOSCH , catalog number 1987947961;
• Trialli , article 5pk1646;
• DRB , 5PK1645; 4PK995 for 1.6-liter engine;
• AYWIPARTS , AW2130184;
• FINWHALE , article number BP5PK1645;
• ASHIKA , catalog number 112-5PK1650;
• CONTITECH , sub-brand Continental, article 5PK1635;
• HERTH+BUSS , article number J1051638.

The same story applies to rollers, but you can save a lot on the roller itself if you buy only the bearing itself. The original bearings supplied from the factory are NSK 6010DU2 . Idler roller assembly 17530-78K00, tension roller 17540-78K00 . Their analogues are produced by several brands under the same catalog numbers: PULLEY, GEN BELT, IDLER, TENSIONER, ASSY .

Analogue of the deflection roller from Herth+Buss

The bearing itself can be of any manufacturer, both domestic and foreign. The bearing size is 80x60(55)x15 , it must be a closed type, maintenance-free. For comparison, the price of the original deflection roller 17530-78K00 is $35, and in a bearing store this will cost no more than 50-60 hryvnia. Chinese is even cheaper, but this is already too much. Here are the numbers of the bypass roller assembly to replace the analogue:

• STELLOX , 0340866sx, price 4-5 dollars;
• INA , 1753078k00, expensive but good quality, cost about $15;
• at the same price, roller 36323 from Gates ;
• Dayco 89144;
• Torque KR5036;
• Otoform/FormPart 20145011/S.

Analogue tension roller

The idler roller bearing is ordered by part number 6203 or SKF: 6203-2RSH ($6) and 6005-2RSH ($7). There is no need to lubricate them; they are pressed into them from the factory with Lubrication life class lubricant for their entire service life. The original tension pulley assembly 17540-77E10 costs at least $170.

Problems with the generator can lead to more serious problems. If electric current is not generated by the car, if it runs on one battery, then battery failure is also inevitable. If there is insufficient production of on-board current, as indicated by the corresponding light on the instrument panel, first of all, it is necessary to check the tension of the alternator belt.

In addition, in many cars, the belt drive we are talking about, which, by the way, is driven by a timing pulley, often connects other critical components. These units are also called attachments. In particular, the belt can drive a pump that pumps antifreeze. So loosening the belt can lead to more than just power problems!

It is regulated by a special roller, which is located on the tensioner bracket.

How to change the bearing in a Grand Vitara roller

Whether it is worth changing just the bearing or replacing the entire roller assembly is up to each person to decide personally, but judging by the prices, it makes sense. Especially if you don’t skimp on the quality of the bearing. To replace it, we will press out the old one and press in the new one. To make the operation go quickly and without problems, we heat the roller without the bearing on an electric stove (or in another way), and put the bearing in the freezer for a while. In this case, the bearing will snap into place without much effort.

1. Remove the tension roller from the engine.

2. Inspect

3. Original NGK bearing

4. To press out the bearing, use a head of suitable diameter and a hammer

5. New and old bearings

6. Place the bearing on the housing

7. You can use a vice to control the alignment of the roller and bearing

8. Be sure to control the accuracy of shrinkage

9. Using the same scheme, we change the bearing in the bypass roller

The process of replacing a bearing is shown using the example of a tension bearing for an M16A engine, but this does not make a fundamental difference.

Replacing the Belt Tensioner Roller of the Kalina Generator

Replacing the alternator belt on Kalina

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 very sagging, 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.

Finding out whether the belt needs to be changed is quite difficult, but certain 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 change it.

Belt selection and price

If the generator design has a tensioner, then the belt is 883 mm. In the vast majority of cases, Kalina has 8 valves. If the generator is like on Grant, the length is 823mm.

When choosing a manufacturer, you should take into account that the official supplier of these belts for AvtoVAZ is the GATES company, therefore preference should be given to its products.

Belts are also created by BTR (many bad reviews), Continental, Finwhale, and ANDYCAR. It is better to buy Dayco 825 (manufacturer GATES), elastic belts are marked Poly-V, if not, then the belt is rigid.

The cost of belts is approximately from 500 to 1000 rubles.

Catalog number 21230-1041056-11.

Prices for alternator belts vary on average from 300 to 400 rubles, depending on the manufacturer, which is not affordable.

Replacement

How to quickly change the alternator belt on Kalina:

1. Release the belt tension by tightening the nut on the tensioner .

• Remove the belt from the roller and all pulleys.
• Slightly turn the belt and pull it out.
• Start a new belt, put it on the roller and pulleys.
• Reassemble in reverse order.
• Start the engine, let it run for a while and turn it off.
• Adjust the belt tension.

The entire procedure for replacing a belt will take on average 2-3 hours; if you have an assistant, it can be significantly reduced.

A couple more tips. If the car has run 60 thousand km, the manufacturer recommends replacing the roller. If the old alternator belt is not completely worn out, it is better to put it in the trunk as a reserve.

A few words about the elastic belt; there is no need to adjust it; it is wound up first on the pulley and then on the generator, put in gear and push the car, having previously slipped a mounting tool or something similar under the belt.

The result of the work

By replacing the alternator belt, you can be sure that the battery will not run out, the alternator will work properly and the car will not become stuck in the middle of the road. And you won’t have to call help or a tow truck.

How to check the attachment belt and rollers of a Grand Vitara

The belt tension of attachments on a Grand Vitara with a J20A engine is adjusted automatically. Nevertheless, it needs to be checked. According to the manufacturer's diagram below, the normal belt tension is determined by the position of indicator A in sectors a, or c. If the roller indicates the position of the tongue in sector c, the belt is definitely stretched and must be replaced even if there are no visual complaints about it.

On 2 liter engines without air conditioning, checking the belt tension is carried out according to the following scheme.

A visual inspection of the belt should show:

• no cracks on the surface;
• absence of chips and visible delaminations of the rubber material;
• there are no tears along the entire perimeter of the belt;
• no traces of oil or antifreeze;
• all 5 streams are intact.

Otherwise, we decide which belt is best to buy and replace it. Signs of roller malfunction are also clear and simple. Most often, on a Suzuki Grand Vitara with a J20A and J24B engine, as well as on a 1.6-liter engine, the idler roller begins to make noise after a mileage of 40-60 thousand; the tension roller can withstand a longer mileage. The slightest play in any of the roller bearings is also considered a sign of wear.
