The VAZ 2110 car is in serious demand among domestic buyers. This is a fairly reliable, moderately powerful product from the AvtoVAZ concern.
Causes of belt breakage
One of the common problems with the model is the failure of the timing belt. The reasons for this may be different:
- Simple wear and tear caused by a long period of use of the vehicle;
- Regular increased loads under which the engine has to work intensively;
- Mechanical damage as a result of improper operation or received during the repair of other components;
- Manufacturing defect.
Regardless of the causes of the problem, it must be eliminated.
Over time, it stretches so much that the gear teeth jump by 1-2 links. This disrupts the valve timing and causes interruptions in engine operation. But this is the best-case scenario for such a situation. The worst is when the strap breaks and the valves bend.
A few words about the importance of correct tension
Many motorists know that improper functioning of the timing belt can cause very serious engine damage. This is due to the principles of operation of the mechanism, which boil down to the timely and high-quality opening/closing of the engine valves. This approach not only allows you to adjust the valve timing of the internal combustion engine, but also differentiates between sensitive valves and constantly knocking pistons.
If the timing belt begins to work incorrectly, the gas distribution order is disrupted, as a result of which engine elements begin to wear out at an accelerated rate. Similar disturbances in the functioning of the engine can also occur due to improper belt tension.
In addition, drive tension that does not meet the standards accelerates wear of the main timing elements, the list of which includes:
- directly the belt drive itself;
- rollers;
- torque clutches;
- guides;
- tensioner
Repair of each of the marked timing parts takes much longer than normal belt tensioning. Well, there is nothing to say about the cost, if you can tighten the drive yourself and completely free of charge, then you will have to pay for replacing the components of the mechanism.
Help in choosing a timing belt and rollers
The reliability, efficiency and operating life of the motor depend on the quality of the rollers and belts chosen for replacement.
Research shows that the cost of a belt is from 450 rubles, and rollers will cost you at least 600 rubles.
When buying spare parts, be guided by the opinions of VAZ 2110 car owners. There are many forums. Also consult with specialists at the service station. They will be able to give professional advice, or even order quality components for you.
Surveys among owners of AvtoVAZ’s creation, namely the VAZ 2110, showed that the most popular belts are products manufactured by the following companies:
- Gates;
- Bosch;
- Kraft;
- Power Grip;
- Dayco;
- Contitech.
As for videos, it’s better to pay attention to the following brands:
- Gates;
- Power Grip;
- VPZ;
- BRT;
- Dayco;
- Marel.
Of course, the choice is purely individual and depends on the financial capabilities and available assortment of a particular store. But if the necessary elements are not available in your city, you can always order them online. Nowadays this is not a problem.
Stories from our readers
“Fucking basin. "
Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.
Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.
- If the belt is too tight, you won't be able to turn it 90 degrees with any fingers.
- if you don’t tighten it enough, the belt will dangle and hit the plastic casing (this shouldn’t happen). We tighten it until the sound disappears at idle and when accelerating.
As a result, if the timing belt tension is correct, then when the casing is removed, its long part will fluctuate within 1 cm. from the axis.
Manufacturer's recommendations
- Your primary task as a car owner is to periodically visually inspect the unit.
- In addition to replacing the element, it is necessary to simultaneously replace the tension rollers.
- VAZ 2110 comes with 8 and 16 valves. The replacement process also depends on this. So, in an 8-valve valve, one tension roller is installed, and in a 16-valve valve, a support and a tension roller are installed.
Replacing the timing belt of a dozen is not difficult. It is not necessary to contact specialists. It is quite possible to do it on your own.
Set of tools
To complete the job of replacing the timing belt you will need:
- A set of spanners and open-end wrenches;
- Mount;
- Screwdriver Set;
- A special key with which to tighten the roller or simple pliers with curved rings;
- Car jack;
- Rags, protective gloves.
Many people ignore the advice on using gloves. Especially in the summer when it's hot. But they are needed to protect you from injury.
There is no need for an inspection hole. You will need to remove the right wheel to remove the timing belt if your Ten is equipped with power steering. So you can't do without a jack.
Belt problems
When replacing the timing belt, you should pay attention to the type of damage that caused the belt to fail. Using these symptoms, you can easily identify signs of a malfunction. Let's consider the causes and consequences of untimely replacement, listing the main ones:
- If it’s frayed, torn or damaged – it’s almost always due to the reupholstery.
- The absence of one of the teeth means weak tension.
- A high degree of tooth wear indicates incorrect tension, as does the presence of wear between several teeth or the appearance of abnormal noises.
- Cracks – temperature differences beyond the calculated limits.
- An oily surface suddenly indicates an oil leak. It is worth replacing the timing belt as soon as possible and finding the leak.
- End wear indicates misalignment, angular or parallel.
Do valves bend on a VAZ 2110?
This problem is considered common among some individual VAZ 2110 models.
Groove for valves
To understand whether the valve is bent on a VAZ 2110, it is necessary to determine which engine is installed. On certain engines (VAZ 2111, 21114, 21124 engines) there are special grooves on the pistons and when the valves break into the pistons, bending does not occur.
On other VAZ 2110 engines such grooves are not provided. (VAZ 2112) Some car enthusiasts grind such grooves on their own on VAZ cars, but this should be done carefully and in checked places because engine compression may be impaired.
Checking the condition of the belt
First, remember that you need to check the condition of the belt once a year, or every 10-15 thousand kilometers. Replacement is carried out after every 50 thousand kilometers.
To examine the status of an item, follow these steps:
- Remove the plug from the protective front timing cover;
- Remove the alternator belt so that it does not interfere with you;
- Unscrew the six bolts, which will allow you to remove the cover;
- Access the belt and examine it.
Removing the timing belt cover
If you notice any of the following, be sure to proceed with replacing the belt:
- The element has bulges or cuts;
- Broken threads and traces of delamination appeared on it;
- There are abrasions, cracks or folds;
- Oil is leaking.
Installation process
First, about what we will need for this:
- jack;
- screwdrivers with different blades;
- hexagons;
- socket wrenches;
- roller tension wrench;
- extension tube.
- We install the car in a level position and fix it.
- Now you definitely need to turn off the power to the car. To do this, disconnect the left terminal of the battery.
- We remove the bolts that secure the belt drive housing.
- Disconnect the crankshaft sensor. Now it’s very important: we check the alignment of the marks that are located on the camshaft gears and on the rear surface of the housing.
5. The marks on the flywheel crown must also match. Their combination must be checked. To do this, unscrew the plug located on the crankcase. The flywheel gear is located above it, and the mark is located on it. It should be aligned with the notch on the crankcase. 6. Now we need to loosen the gear tension and check the position of the mark on the crankshaft pulley. Now you can remove the belt. In this case, the flywheel must be fixed. To do this, you need to insert a metal pin between the crankcase and the crown. 7. Now take the 17 key and unscrew the bolt securing the generator pulley. We check the marks placed on the oil pump and crankshaft gear.
8. Take a 15mm wrench and remove the tension roller. We remove the timing belt drive and begin installing a new consumable. 9. First, pull the belt onto the generator pulley. Use a special wrench to turn the tension roller to the right. This is done using a special key. If you don’t have one, then pliers with curved tips will do just fine. Adjust the belt tension. It should be optimal - the belt should not sag, and it should not be overtightened. If you grab the belt with your fingers and can only turn it 90 degrees, then everything is fine. Incorrect tension will certainly lead to premature wear of the belt drive. 10 We assemble all other parts from the reverse. Don't forget to remove the screwdriver that we jammed into the crankcase. 11. Now all that remains is to start the engine and check its operation. If there is no extraneous noise and the engine runs as usual, then everything is fine.
Belt replacement
Replacing the timing belt must be described separately, depending on how many valves your VAZ 2110 has - 8 or 16. Self-repair of the unit on an 8-valve engine is considered easier, although you should not have any serious problems with a 16-valve engine.
8 valve
The sequence of work will be as follows:
- Disconnect the battery by removing the negative cable;
- Unscrew the bolts from the belt protective cover;
- Remove this protective cover;
- Remove the front wheel on the passenger side, while simultaneously removing the mudguards and engine compartment protection;
- Turn the generator pulley clockwise so that the marks on the cover and the pulley match;
- Remove the protective plug from the gearbox and check in the resulting hole to see how much the control marks match;
- Using a metal screwdriver or other object, you need to block the flywheel;
- After this, you can unscrew and remove the generator pulley;
- Make a few turns to loosen the nut that holds your belt tensioner pulley in place;
- Remove the old belt. You won’t need it anymore, so feel free to send it to the landfill;
- The space needs to be cleaned and degreased. White spirit is perfect for this;
- After rinsing, dry everything using a dry and clean cloth;
- Install the new roller following the direction arrows. If they are missing, then take the inscription into account. It should be located from left to right, that is, you could read it without any problems;
- To tighten the belt, move the roller counterclockwise;
- Check that all marks and the degree of belt tension match correctly;
- The compression ratio should be checked on a cold engine and at an air temperature within 15-30 degrees Celsius;
- Turn on the motor and with the unit running, check whether you have installed everything correctly;
- If the sound is normal, then the installation was completed correctly;
- Reassemble the removed elements in reverse order.
The replacement can be considered complete.
16-valve
Diagram of the timing mechanism 16 valve VAZ 2110
The VAZ 2110 is equipped with two types of engines - with 8 and 16 valves. At the same time, replacing a 16-valve valve is considered more difficult. Experienced craftsmen assure that for a high-quality timing belt change it is enough to put in a little more effort and attention.
Therefore, in this case, the work must be done as follows.
- Remove the six nuts that hold the protective cover in place. Remove the protection cover.
- Release the crankshaft sensor.
- Find an area on the pulley that is missing a tooth. It will act as a guide to find top dead center.
- Install the piston from the first cylinder so that it is at top dead center.
- Align the pulley and crankshaft sensor, lock the pulley, unscrew and remove it.
- Next, loosen the nut located on the tensioner pulley.
- Remove the old belt and also remove the tensioner pulley.
- Clean the freed space from dirt, oil, and clean it with a dry cloth.
- Install a new belt and secure the pulley with bolts. It is recommended to replace the roller itself at the same time.
- Make sure that the belt and drive marks match, as well as the timing gear marks.
- Tension the belt using the tensioner roller.
- Check the elasticity after stretching.
- Make two full revolutions of the crankshaft to check the quality of the assembly.
- Make sure that the marks match, after which the pulley can be installed in place.
- Turn on the engine, check for correct installation, and then reinstall the protection casing.
Features of model 2110
The features of this model include the following:
- Availability of ventilated brake discs.
- Galvanization of parts that most often rusted in older models.
- On-board control system.
The gas distribution mechanism on the VAZ 2110 suffers from frequent breakdowns, or more precisely, from damage and ruptures of the timing belt, which is a closed rubber ring, the dimensions of which vary in different engines. It is possible to replace it without any particular difficulties; if you have time, you can figure out this procedure yourself, saving on repairs in the workshop.
And also, its damage may indicate problems with the gas distribution system, which are worth investigating. Let's look at how to replace a belt and analyze damage to the timing belt.
About the engine
The engine performance of the 2110 is quite good for the time it was produced.
On 2110 cars, a variety of engines were installed, both carburetor and injection, with 8 valves (VAZ 2111, 21114) and with 16 valves (VAZ 21120, 21124).
List of VAZ 2110 engines:
- 2111,
- 21114,
- 21120,
- 21124.
According to the standard, the VAZ 2110 was equipped with an 8-valve engine, in variations numbered 21114 and 2111, which differed in minor characteristics. The 8-valve engine, marked 21114, earned the greatest recognition due to its high power and relatively low fuel consumption.
The standard operating mileage for this engine is 250,000 km. When using high-quality oil poured into the engine, you can extend the life of the car by 20–30 thousand km.

Tension roller upside down
I've been dreaming about a Priora since birth
Fuck it... LOMASTER... The tension roller is positioned incorrectly... And how did he unscrew the generator drive pulley... PPC... Complete bullshit
Delete the video, don’t confuse people, mechanics are cross-handed.
the hat is full They seem to be doing this for the first time And at the end of the video the belt turned and wow the head
some kind of fucking shit, why I don’t know how to turn the nuts, show me how to set the ignition
Error in roller tension. It is pulled counterclockwise until the groove and the notch on the roller itself align.
gentlemen, everything is correct, but the roller is tensioned counterclockwise and not...
Dumb or what?
hmm... a visual aid of WHAT NOT TO DO.
idiot, he probably sees Priora for the first time in his life. How did he determine that he had tensioned the belt correctly? I wonder how long this video goes when placed with its horns down?
The roller is on the opposite side, the slider indicating the belt tension should be at the top, but here it is directed downwards. It is very important to know whether it works or not and the roller is tensioned counterclockwise and not for me. I sincerely feel sorry for the owner of the car, who probably ended up with expensive repairs.
Shorashkina office
The fucking roller is tensioned counterclockwise.
I didn’t even bother watching, it was enough for 3 minutes
I bought a new Priora, after how many km do I need to change the timing belt???
mileage 20 thousand. I'm worried about the timing belt. :-
I'm not very good with cars, but I replaced the timing belt and pump myself after watching a video on YouTube, and I've seen enough of local car mechanics that it's a pity to give them the car
the tension counterclockwise seems to stretch
