➤ Timing belt on Lada Granta. Reasons for the break

A broken timing belt and its subsequent replacement is a fairly common problem among owners of a Grant car, both with an 8-valve engine and with an engine with 16 valves installed.

Very often among car enthusiasts you can hear a conversation that, due to a torn belt, the engine seized or the valves were “bent”. Why this happens and how to prevent such a phenomenon, as well as how to change the part yourself, will be discussed in our article.

Timing belt. What is it for?

To transmit torque from the crankshaft to the timing system, most modern cars use a drive belt. Car mechanics and drivers call this part a timing belt. This product is made of durable rubber, reinforced with a special fiberglass cord. For better traction, it has teeth that match the size of the notches on the crankshaft and camshaft pulleys.

The belt performs an extremely important function in the operation of the engine, ensuring a smooth cycle of the intake and exhaust mechanism, and removing exhaust gases to the outside. In addition to the engine shafts, the timing belt on the Grant 8 valve also drives the coolant pump, which is called the “pump”. Without a reliable drive, the operation of the power unit is impossible in principle, so each driver needs to carefully monitor the integrity of the part and replace this element within the prescribed time frame.

About engines

Lada Granta engines with 8 valves in the cylinder head are indexed 11183 and 11186. The first of them began to be produced in 2004, the second later, namely in 2011. The power of the “83” unit is 82 horses, with 87 hp for the “86” modification. Motor 11186 is an improved engine of the “83” model. It uses a lightweight connecting rod and piston group. It was possible to achieve a reduction in the mass of the piston group by almost 30%. The cylinder head is subjected to specific heat treatment, which increases its strength and wear resistance.

The cooling system of the power unit also received some changes. The skirts of lightweight pistons are coated with graphite lubricant, this avoids the appearance of scuffing on the cylinders of a cold engine. The compression ratio of the “86” engine became 10.5 versus 9.6 for the “83” modification. The cylinder head gasket of the new engine is now thinner, it is 0.43 mm versus 1.2 on the old model. The diameter of the intake valves was increased, which improved the filling of the cylinders with the air-fuel mixture.

Does the valve bend?

Unfortunately, this problem exists for the Lada Grant. It appeared from the moment the production of the first cars with front-wheel drive, the VAZ 2108, began. Subsequently, the working volume of the power unit of this model was increased, it became equal to 1.5 liters. The engine index became 21083, in which the pistons have a recess in the head. This made it possible to prevent the pistons from meeting the valves if the timing belt in the timing drive breaks or is installed incorrectly. This particular power unit was taken as the basis for the engine for the Granta, so there were no valve bends.

Upgrading this engine to model 11186 involves installing lightweight parts of the connecting rod and piston group. The pistons have become shorter in height, which does not allow making recesses in the head to prevent them from meeting the valve. Therefore, a toothed belt break is always accompanied by damage to the valves on an 8-valve Grant, sometimes to connecting rods and pistons. This problem accompanies all subsequent modifications of engines for the Lada Grant.

Timing belt replacement period on Grant

The manufacturer of Lada cars, the AvtoVAZ concern, stipulates the timing for replacing the Granta belt - 75 thousand km. The established term applies to all Grant cars, regardless of the number of valves.

In addition to scheduled replacement, a prudent driver always monitors the condition of the drive, since it may break prematurely due to its poor quality or improper installation. Therefore, the decision “how long does it take to change the timing belt on a Grant?” Each driver decides independently.

Why does a belt suddenly break?

In some cases, even a new part can suddenly break, causing a lot of inconvenience to the owner of the vehicle. Most often, the teeth are worn out due to the fact that the Grant timing belt was installed incorrectly. In this case, it runs crookedly on the pulleys and rollers and its teeth “eat” the metal elements of the pulleys.

Other causes of premature wear may include:

Poor part quality. In this case, savings can play a cruel joke on the driver, so you need to make a purchase in trusted stores
Pump malfunction. This is one of the most common causes of breakdown. The pump rollers break over time, forming a gap and displacing the axis. As a result, its teeth quickly wear out and lead to breakage.
Tension roller malfunction. The same thing can happen with a roller as with a butt. A bearing failure creates play and displaces the tension axis.
Oil or antifreeze leak. When technical fluids get on the belt, they destroy the rubber from which it is made and greatly affect the strength of the part.
Wear of pulley teeth. If the camshaft or crankshaft gears are severely damaged, integrity will be immediately affected. In this case, the teeth will have delamination on their surface.

In addition to all of the above, the fact that the timing belt on the Lada Granta 8 suddenly breaks can be caused by a trivial reason for its untimely replacement.

Tests and tests

Experts from the Za Rulem magazine tested 36 drive belts - 6 copies of each from six different brands. The test results refer to specific product samples and do not allow us to judge the entire range of products of each item.

Recommended:

Continental, Germany. Approximate price 850 ₽. There can be no complaints about a belt that has stood for 400 hours on the stand and could continue to work. In our tests, only two products were able to demonstrate this.
Gates, UK. Approximate price 1150 ₽. 400 hours on the bench are sufficient grounds for unequivocal approval.
Trialli, China. Approximate price 700 ₽. 286 hours is, let’s say, a strong middle peasant, which, unlike the leaders, nevertheless became toothless, although it lasted quite a long time, exceeding the requirements of the technical specifications. At the same time, strength tests have shown that some belt parameters are even better than those of the champions.

Not tested

Gates (fake with reference to Germany). Approximate price 350 ₽. Which is what needed to be proven: “You, priest, should not chase after cheapness.” After just 3 hours of life tests, the belt lost its “teeth”: a complete failure. Checking individual parameters confidently placed the product in last place: such belts cannot be installed!
Lynx, Japan. Approximate price 650 ₽. During endurance tests, the belt lasted 104 hours, after which some of the teeth were cut off. In general, not so little, but the leaders worked four times longer and were not injured! The remaining parameters are not failures, but overall we are looking at an mediocre product.
Balakovorezinotekhnika (BRT), Russian Federation. Approximate price 750 ₽. Just 1 hour on the stand instead of the champion 400 - what can I say? Alas, the teeth came off the cord almost immediately. It feels like the belts are made of raw rubber. Note that after drying, the cutting force of the tooth more than doubled - and this turned out to be the best result. But the breaking forces are low, and according to the results of bench tests - the penultimate place.

Consequences of a broken toothed belt. Is everything really that scary?

The manufacturer installs several types of power units on Grant cars.

There are 5 of them in total:

VAZ-11183-50
VAZ-11186
VAZ-21126
VAZ-21127
VAZ 21126-77

The first two are eight valve, and the rest are 16. Sad consequences in the form of damaged valves due to a broken timing belt on Grant threaten all of these engines, with the exception of the VAZ-11183-50.

It goes like this. When the timing belt breaks on a Grant car at high speeds, this leads to the connection between the engine shafts being lost. The camshaft stops abruptly, but the crankshaft continues to move as the engine is running. As a result, the piston hits the stationary valves sharply, which can bend and even break. Such damage threatens with expensive repairs of the entire gas distribution system, and if the piston is also damaged during the impact, then replacement of the piston group, which is even more expensive.

How to determine that a break may soon occur

Urgent replacement of the timing belt for a Granta car of 8 and 16 cl. may be necessary if the following phenomena occur:

Decrease in vehicle power. A poorly tensioned or worn drive can make the engine difficult to start and reduce power output.
Incomprehensible noises from the timing belt on the Grant, emanating from the engine compartment. Clunking, ticking or strange rustling noises often indicate that the Granta timing belt is damaged and rubbing against the casing or other parts under the hood
Visible damage. The part may have abrasions, cracks and “shaggy” areas that are visible to the naked eye.

Replacing the belt on an 8-valve Lada Granta engine. Detailed description

After making sure that the part is in poor condition, you need to prepare for the procedure of replacing the timing belt on a Lada Granta 8 valve. First of all, you need to provide a comfortable place to work, well lit, spacious enough and safe.

Tools you will need:

Wrenches included in the set
Heads with extension
Mount
Special device for adjusting the roller

The tensioner pulley is often replaced at the same time, so it is necessary to purchase it in advance. In all stores you can buy a timing belt pulley for Granta as a set.

Before starting work, you must unscrew the ground wire from the battery.

Let's consider the process of replacing the timing belt on a Lada Granta car using the example of an 8-valve engine. Main stages of work:

Preparing for repairs. The car is jacked up and the front wheel is removed from the right side, as well as the protection that blocks access to the engine.

Removing the protective cover. On Grant cars, the plastic cover consists of two parts. It's easy to remove. First you need to unscrew the 4 bolts of the upper part, and then the lower part.

To do this, you need to use a 5-point hex key. In addition to the cover, you also need to remove the crankshaft position sensor by simply disconnecting it from the connector and removing it from the socket.

Alignment of marks. Before replacing the timing belt on Granta 16 and 8 valves, it is necessary to correctly set the engine valve timing. To do this, you need to turn the crankshaft clockwise. This is done using a 17-inch socket. You need to turn it until the mark on the camshaft toothed pulley coincides with the mark on the inner surface of the timing cover.

In addition, the marks must line up on the engine flywheel. This can be checked through a special hatch in the upper part of the clutch housing. After removing the rubber plug, you need to make sure that the special protrusion on the flywheel coincides with the camshaft mark.

Only after this can you continue replacing the timing belt on the Lada Granta.

Removing the generator pulley. To prevent the shafts aligned to the marks from turning, the flywheel can be locked through the inspection hatch. The most convenient way to do this is with a thick screwdriver or pry bar. Having firmly secured the flywheel, carefully unscrew the nut holding the generator pulley and remove it along with the washer.

Next, loosen the generator pulley nut

Adjusting the tension roller. Using a 15mm wrench, you need to gradually loosen the tightening of the roller mounting bolt. When the fastening is loosened enough to allow sagging, you can begin dismantling, making sure once again that all the marks match.

Withdrawal. The part is carefully removed from all pulleys and removed from the engine compartment. If there is a complete break in the timing belt on Grant's car, this is even easier to do.

Helpful advice: while you are changing the timing belt on the Grant, the protective cover is removed and you can check the condition of the water pump and tensioner pulley. The video is removed and played in the hands. If there is no extraneous noise and the bearing does not jam, it is installed back. The water pump is checked by twisting it by the pulley. If nothing sticks, she's fine.

Installation of a new spare part.
Before use, the timing belt on Grant 8 valves is checked for manufacturing defects - peeling, cracks, excessive roughness of the material. It would be useful to look at the expiration date, since rubber loses its properties even without being used, but after lying on the shelf for several years. The number of teeth on the Lada Granta belt with an 8-valve engine is 113, and its width is 17 mm. Installation of the part is carried out in the reverse order. First, it is pulled onto the crankshaft, then onto the generator and pump, circling the roller, and at the very end - onto the camshaft. Tension. To ensure good tension, you need to rotate the roller counterclockwise. This is done using a special key, which consists of 2 metal rods. These are inserted into the corresponding holes on the roller and the roller is rotated until the cutout on the roller cage aligns with the rectangular mark on the inner sleeve. Only after this can the roller bolt be tightened.

Replacing the timing belt on a 16-valve engine. Process Features

The process of replacing the timing belt on a 16-valve Grant is not much different from the similar process on an 8-valve one. But there are some differences, which are that the 2 camshafts have different marks and they are set slightly differently.

In addition, replacing the timing belt Grants 16 valves automatic is complicated by the fact that to carry out this work it is necessary to remove the starter, which blocks access to the flywheel. The timing belt size of the Lada Granta with a 16-valve engine is 137 teeth with a width of 22 mm. Removing the starter on the Lada Granta Removing the starter is not difficult. To do this, just do the following:

Disconnect the plastic connectors from the starter
Unscrew the nut that holds the power terminal. To do this, use a key of 13
Using the same wrench, unscrew the 3 bolts that secure the starter to the bracket.
Hold the starter housing and carefully remove it.

After removing this element, you can begin replacing the timing belt. How to set marks on a Grant with a 16-valve engine Since a 16-valve car has 2 camshafts, the marks on each of them must coincide with the recesses on the top of the timing cover, as well as with the engine flywheel. By turning the crankshaft to the right until these marks coincide, the camshafts need to be fixed. A small piece of soft wood or an elastic piece of rubber is perfect for this purpose.

After the marks match, the flywheel is fixed in the same way as on 8-valve models.
Support roller

In an engine with two camshafts, in addition to the Grant timing belt tensioner, there is also a support roller. It performs the function of additional stabilization of the belt, adjusting its correct position in relation to other parts and better functioning of the entire belt drive. Like the tension roller, it must be checked for defects and, if necessary, replaced with a new one.
