LOCATION

Finding the Alternator belt in a VAZ 2114 is not difficult; when you open the hood, it is immediately visible. There are 2 criteria by which you can easily see it - firstly, it differs from all other belts in that one of its sides is toothed, and secondly, it connects not only the crankshaft and camshaft, but also passes through several small auxiliary parts . If you still don’t understand where it is, let’s first find the generator itself, it is located to the left of the car engine, not far from the right headlight, on the right side of the passenger compartment - accordingly, the belt is located on the generator itself (logically).

Also, before talking about changing, it is necessary to mention that in any case, no matter how carefully the car is operated, and no matter how often you drive it, the alternator belt will begin to deteriorate. Perhaps it will slide, or maybe it will be eaten away, it doesn’t matter, the main thing is that in any case it will become unusable. Therefore, its condition must be monitored very carefully, because no one wants it to break on a long journey.

Adjusting belt tension

Incorrect tension of the alternator belt can have an extremely negative impact on the operation of the components and assemblies that depend on it. Thus, too weak a tension will lead to its slipping, leading to unstable operation of the generator (due to poor transmission of torque) and interruptions in the on-board network (including rapid battery discharge).

On the contrary, an excessively tight belt tension can cause excessive stress on the generator bearings, thereby leading to their rapid wear or even destruction. It is for this reason that the tension value is extremely important and should be checked periodically.

In order to correct it and return the belt to normal operating condition, you need to:

• loosen the generator fasteners from below and from above;
• turn the adjusting bolt and thus tighten the tension (to increase the tension, rotate the bolt to the right, to loosen it, to the left);
• Using a wrench, turn the crankshaft several turns and check the tension;
• If the tension is OK, tighten the generator fasteners.

VAZ 2114 generator belt tension

The tension check itself can be done by simply pressing the belt with your hand. If it is tensioned correctly, its deflection will be about 8 mm. If the deflection is greater, the tension should be increased; if it is less, it should be weakened.

You can check the correct tension in another way - just put the multimeter in DC voltage measurement mode with a limit of 20 volts and measure the voltage at the battery terminals with the engine running. Stable readings will indicate that the belt is tensioned well (which means that rotation is transmitted smoothly to the generator). If the voltmeter readings fluctuate, the belt tension should be adjusted.

Another clear sign of proper belt tension is that it runs silently. If it moves smoothly, without making a whistle, hum or other extraneous sounds, then everything is fine. If any noise is heard during its operation, it means that the tension was performed incorrectly (in some cases, the cause of the noise may be jamming of the generator, as discussed above.

That is why, if after repeated attempts to adjust the belt tension it is not possible to remove the whistle, you should pay attention to the condition of this device).

CHANGING THE GENERATOR BELT

Surely, if you are looking for tips on how to remove the alternator belt and then put it back in place, you have already encountered the problem of its malfunction. Know that in order to perform the replacement correctly, you do not need to contact a car service; you can easily perform this procedure yourself . So, first we need to decide what tools we need to replace the alternator belt:

• Socket wrenches for 17 and 19, you can also use open-end wrenches;
• 10mm socket;
• Special tension wrench;
• Flat screwdriver;
• Ratchet wrench.

Attention! Before starting work, be sure to remove the negative terminal from the battery.

Further work must be performed according to the following instructions:

What threatens a broken timing belt on a VAZ 2115 engine?

VAZ 2115 can be equipped with three types of engines:

• gasoline carburetor eight-valve VAZ-21083 with a volume of 1.5 cm3 (from 1997 to 2000);
• petrol with distributed injection eight-valve VAZ-2111 with a volume of 1.5 cm3 (from 2000 to 2007);
• gasoline with distributed injection eight-valve VAZ-11183 with a volume of 1.6 cm3 (after 2007).

Fortunately, the owners of the “tag” on none of the engines, when the timing belt breaks, the valve does not “bend”, but such a malfunction can still become quite an unpleasant surprise for the driver, especially on a long trip. Some practical VAZ 2115 owners who have encountered such problems often carry a spare belt with them, because if it breaks, it can be changed without much difficulty. Of course, if you have some experience and a set of tools at hand.

REMOVING THE ALTERNATOR BELT

1. First, you need to put the vehicle on the handbrake with fourth gear engaged;
2. Next, open the hood and remove the protective cover from the belt, now you need to loosen the tension, then you can remove it;
3. Now we remove the generator drive pulley from its place, while leaving its bolt in place. Remove the vehicle from gear.
4. Then, you need to turn the crankshaft clockwise, while you need to keep an eye on the mark and the flywheel, they are visible in the hole in the clutch housing. You need to twist it until it becomes parallel to the middle strip of the scale;
5. When the mark is in the indicated position, you need to unscrew the tension roller, by the way, with the help of it the tension is released. Now we remove the damaged spare part.

VAZ 2115 timing belt which is better

Dear visitors of the site “All about cars”! We will be very grateful for your comments on the video clip “Which VAZ 2115 timing belt is better”, registration is not required for this. We also ask you to let us know if you have any problems playing the video.

Thanks bro very helpful advice

In engines that use a timing belt. The camshafts have toothed pulleys. Not sprockets, not gears, but pulleys. Gentlemen, you need to use technically literate language. 

Zheka help me with advice. The belt broke on a VAZ 2108 1. 3. I changed the belt, I put it on the marks, it started but it doesn’t work confidently and at high speeds it shoots into the silencer and dips when you press the gas. I did the ignition earlier and it didn't help. when I move the camshaft gear onto the tooth clockwise everything is normal and it works and is in motion. but this is no longer according to the marks. how to cure????? 

I was just 13 years old and I didn’t know what the belt was... and it turned out to be a pump 

Often people over-tighten the roller and the pin bends. the video will be skewed. 

Only a dumb idiot can not remove the old stuck gasket when replacing the pump, it's just fucked up

I have a 96 Opel Vectra. I bought a Gets belt and how do I know if it’s original or not? And how do I know if I need to change the pump or not? Do Gates timing belts work or not? Please tell me 

Please tell me if a little bit of oil from the shaft gets onto the timing belt and the shaft has a balance, the shaft plays, then the timing belt breaks these things.? I have an Opel Vectra installed with a belt, but I haven’t changed the tensioner rollers. and after 25 thousand the belt broke and bent all the valves. changed the valve. I told the mechanic to open the crankcase and wash it. he opened it and said that your shaft is running and leaking oil from the front oil seal. It just so happens that it can affect the mileage of the belt? For example, it was supposed to be 40 thousand, but it was 25 thousand. 

I ask you for an answer. Evgeni. 

Now I have changed the shaft, the valve ring, all the seals, all the gaskets. and washed the block and crankcase. How correct did I make it? I did not change the pump, the pump is in good condition. 

If you change the belt and do not change the tensioner rollers, do they affect the mileage of the belt? The rollers made noise and when the belt broke, but the rollers did not spin, they did not jam. Is everything working on the timing belt? 

Evgeniy, according to manufacturers, which pumps are currently best for the 126 engine, and do you even need to lubricate the timing rollers before purchasing?

It is better to place the pump on a sealant or gasket on a VAZ engine

There are many reasons and the pump is not the only one. I know from my own rich experience. 

The pump ate up 4 belts.. Damn, couldn’t it be replaced right away?

Thank you very much Zhen, I was already thinking about changing the roller and all the pulleys on the spot, but it turns out it’s all so simple

thank you very much for the advice. Maybe for some it’s a small thing, but for me it’s a small victory. I changed the timing belt with the pump myself. and everything is in order. The belt is in place, does not chew, does not eat or bite. 

But the right topic is right...

Good day guys I have an urgent question, I drive a 2003 VAZ 2112 8 valve, the engine was overhauled 3000 kilometers ago, there are no complaints about the engine’s performance, and a week ago the oil suddenly darkened, what could it be?

WHAT DO YOU NEED TO KNOW?

You have successfully removed the belt from your fourteenth, now in order to install a new one, you need to purchase it. You can buy a new part in any store that sells parts for domestic cars, it doesn’t cost very much, 100-400 rubles, this amount depends on the region of the country.

Important: before you run to the store, be sure to find out what the size of the alternator belt on the VAZ 2114 is in your case. If for some reason you cannot take the measurement, you can take the old one with you for demonstration and purchase the same one.

VAZ 2114 timing belt roller which is better

Dear visitors of the site “All about cars”! We will be very grateful for your comments on the video clip “Which VAZ 2114 timing belt roller is better”, registration is not required for this. We also ask you to let us know if you have any problems playing the video.

Sandro, give me advice on which roller and which belts are best to buy?

and what did you want from spare parts if initially spare parts for Zhiguli were sold in grades 2, 3, 4, and now they even sell rejects and there are countless left-handed companies selling spare parts. That’s why the factory ones take a long time and the quality control department still works sometimes 

I absolutely agree with the quality of spare parts in the store, or rather anti-quality... Thanks for the video Like

San, do you have diesel for cold weather?

hello.. help please.. Kalina sedan.. the tank is deflating, what’s the problem? changed the cover 

70000

The original gene belt came off at 105,000 thousand km, the pump at 130,000 thousand km, the timing belts were changed after 60,000 thousand km, the total mileage was 160,000 thousand km.

Yes, it’s true that factory parts are much better than analogues from stores

On 8 bugs, put Balakovo, timing belt or generator. The wholesale price of Balakovo is more expensive than its Chinese counterparts. STRAPS are better than Chinese fin whales and lazars 

And the tension roller of the generator belt is repairable. Is it possible to knock out the bearing from there without damaging the plastic??? 

115 thousand, normal flight, factory pump and factory alternator belt and tensioner pulley, no noise, no buzzing

Basin

130 thousand went and did not break Kalina 1, 6 8 valves.

The hole in the pump is for the bearing mounting screw.

Listen, what kind of alternator belt do you have, 6RK 738?

If such a roller is filled with blue lithol, how long does it last?

Hello, engine 1. 4 valves 16 had a cond, but it broke through the radiator and took it off and left the compressor, so the question is which belts are better to use, from whose companies???

Lubricate the timing rollers and other bearings more often and it will last a long time.

take normal spare parts

REVERSE INSTALLATION

When you have purchased a new part, it is time to figure out how to install the alternator belt. This procedure is performed in the following order:

1. We put the new generator belt on the camshaft pulley, now we tighten both branches;
2. The part that is not tensioned is tightened by the roller, put on the pump and crankshaft pulley, then we tighten the belt by reverse rotation - counterclockwise;
3. We turn the crankshaft about 2 turns, check the positions of the marks, they should be in the middle;
4. If the marks do not match, repeat the entire procedure until you can set them correctly;
5. You need to unscrew the crankshaft bolt and put the generator pulley in its place, then tighten it with the bolt. This is done by turning the roller counterclockwise;

How long does it take to change the timing belt?

The service life of the timing belt depends on the make of the car, and information about its service life is usually listed in the technical documentation. Experts recommend replacing the belt on domestic cars when the mileage reaches 50 thousand kilometers. If you purchase a used vehicle, it is recommended that you carefully inspect the timing belt for signs of wear. Even if the belt does not sag, but microcracks are noticeable on its surface, it is recommended to replace it.

It should be noted that the appearance of microcracks does not threaten immediate belt breakage, since the timing belt has a sufficient safety margin designed for prolonged shock loads, however, its weakening has a negative effect on the dynamics of the car - the engine is more difficult to start and begins to operate noisier than usual.

Fan belts - description and dimensions

Fan belts GOST 5813-93 for cars, tractors and other equipment are designed to transmit motion from the engine shaft to auxiliary units. For fan belts in accordance with GOST 5813-93, the belt length is indicated along the design line (cord). Operable at temperatures from -40°С to +60°С.

Wp - design width of the belt, mm (cross-sectional width of the belt under tension at the level of the neutral line); W—width of the larger belt base, (mm); T—belt height, (mm); α - belt wedge angle equal to 40°±1°

Example of a symbol: Fan belt 11x10-1500, where: 11 - estimated belt width (mm); 10 — height of the belt section (mm); 1500 - estimated belt length (mm)
