We set the VAZ 2109 timing belt according to the marks independently in 10 minutes

The parts that are responsible for opening and closing the engine valve are installed along with the drive belt. The belt is often subject to wear and tear and is quickly used up. change the VAZ 2109 timing belt yourself, without turning to specialists for help. In this article we have collected complete information. You will soon see that replacing the VAZ 2109 timing belt is simple and does not require special skills. Enjoy reading.

The engine GMZ controls the valves and cylinders. This set of parts begins to work using a belt. According to the standards, replacement of the timing belt and shaft belt in the VAZ 2109 and VAZ 21099 is carried out every 40-50 thousand km. Experts say: “If you have time to replace the belt, the driver will reduce the likelihood of cracks and breakage.”

Many car owners turn to specialists for help. But, as practice shows, it is quite possible to replace the belt on a VAZ 2109 yourself. Replacing the VAZ timing belt will not take you much time. Just follow the instructions.

Preparing to replace the belt

Replacing the crankshaft belt requires some preliminary work. To do this, lift the hood and remove a small section of the air duct pipe, loosening the fastening elements with a wrench. Then the protective front part of the belt guard . Before doing this, you need to loosen the three mounting screws. You can use a regular open-end wrench.

The front right wheel is removed in advance to gain access to the crankshaft. In the car, put the switch in the fourth position and ask an assistant to hold the brake pedal. Now install the 19mm socket on the long wrench. After the screw is unscrewed, you can put the gear in neutral and release the brake pedal.

When to change timing belt

As practice shows, the frequency of replacing a belt on a VAZ 2109 should be every 80 thousand km. But, most vehicle owners prefer not to bring the belt to the specified value, and change the timing belt after 45,000-50,000 km. The reason for replacement may be related to the operation of the equipment in different temperature conditions, as well as the unstable behavior of parts.

To avoid breakdowns, it is recommended to assess the condition of the belt. This assessment is carried out annually or every 8-15 thousand kilometers. To complete the inspection, it is important to remove the plastic front drive unit.

The belt should be replaced in the following cases:

• when scratches are detected;
• tears appeared on the belt or it began to delaminate;
• Oil began to appear on the belt (it is necessary to identify and eliminate the sources of engine oil spills).

Tools and materials

Before you start replacing parts, you should do a lot of preparation. First things first, prepare your tools and materials:

• a set of wrenches or sockets (sizes 8, 10, 17 and 19 mm);
• a screwdriver with a thick tip;
• rotary wrench for tension roller (industrial or handmade);
• tool for replacing spark plugs;
• marker for making marks on parts;
• cloth for cleaning the lid;
• new belt;
• video clip.

If you don't have a wrench, you can install the roller using two suitable pins and pliers. The pins are inserted into the holes and rotated with pliers.

Belt selection

When purchasing a timing belt for a VAZ 21099, it is important to focus on the manufacturer. According to customer reviews, products from Gates and Contitech factories have an ideal balance between quality and value. Many experts recommend installing a Gates tension pulley. The part has high build quality and can last for many years.

Video

The procedure for replacing a camshaft belt and a worn pump is presented in a video from the Nik Nikolsson channel.

Aligning the timing marks is a very important step when performing many repair or adjustment work on the VAZ 2109. For example, this procedure is required when adjusting the clearances in the valve drive. This is quite simple to do, but it is worth devoting a separate article to this material in order to show everything more clearly and in detail.

To carry out this work, we will need a few simple tools:

• 10mm wrench or ratchet socket
• thin flat screwdriver
• jack

So, the first step is to lift the right front part of the car with a jack so that the front wheel is suspended. The photo below shows an example on Kalina, but there is no difference between the engines, so you shouldn’t pay attention to it:

Next, you need to open the hood of the car and remove the casing, under which there is a drive star for the VAZ 2109 gas distribution mechanism. It is usually secured with a pair of bolts from the end:

Next, remove the protective casing, moving it slightly to the side, as is more clearly shown in the picture below:

Now you need to put the gearshift lever in the 4th speed position and rotate the front wheel by hand, while looking at the camshaft pulley. It is necessary that the mark on the gear coincides with the protrusion on the cover:

That's not all. Now, using a thin screwdriver, we pry up the protective plug, which is located in the gearbox housing, next to the engine joint, and in this window, the mark on the flywheel should also coincide with the mark on the housing:

If your marks do not match, then you need to adjust them to set them clearly. To do this, we first ensure that the mark on the flywheel matches. If at this moment the marks on the camshaft do not coincide, then it is necessary to remove the timing belt from the sprocket and rotate it until the marks align. Throw the belt back on and then you can do all the work that is necessary.

Removing the old timing belt

To remove the old belt, do the following:

• Unscrew the spark plugs. This will make it easier for you to remove the old belt.
• Rotate the shaft by the pulley bolt and mark the material. Experts advise turning the shaft several times to make sure that you are doing everything correctly. Accuracy will allow you to set the phases correctly.
• Mark with a marker the general position of the belt on all gears. This mark can be placed on the belt and other parts.
• Unscrew the nut connecting the tensioner pulley with a 17 mm wrench.
• Release the belt tension by turning the roller with a wrench or the pin with pliers.
• Carefully remove the old belt from the engine.
• Take the old part and compare it with the one you bought.
• Remove the tension roller. Many experts recommend changing not only the belt, but also the assembly along with it. In this case, it does not matter what state the node is in.

Installation

Now directly about how to return a new timing belt to its place. There is nothing complicated here either, but we still recommend watching visual videos and studying the instructions.

1. As soon as you have examined the condition of the unit and decided to change something, proceed to assembling the mechanism.
2. It is easier to do the work so that all the inscriptions are turned in your direction, that is, towards the right wing of the car.
3. Replace the pulley unless it needs to be replaced.
4. Next, put on the belt. Moreover, it should be put on the lower gear first, and then on the upper one. Not the other way around.
5. Make sure there is no sagging.
6. Place the timing belt behind the water pump and tension pulley.
7. Tighten the tension roller using a special wrench.
8. If you do not have such a key, use a simple key and a screwdriver.
9. Be sure to adjust your new strap properly. The adjustment is carried out until the moment when you can no longer turn it at an angle of more than 90 degrees. This is the best option for tightening the strap for the VAZ 2109.
10. Turn the pulley several times. This will ensure that the marks on the timing gear and flywheel are in the correct position.
11. If for some reason the tags do not match, we have bad news. You will have to remove the strap again and adjust the position again.

The main difficulty in replacing a timing belt lies not in the complexity of the processes performed, but in the time that needs to be spent on repairs.

A competent approach, attentiveness and the use of a high-quality new belt will allow you to easily restore the operation of the gas distribution mechanism and save hundreds of rubles on visiting a car service center.

To make driving a car enjoyable, you need to constantly monitor its technical condition and regularly change all consumables. is one such material. The article provides instructions for a VAZ 2108 with a carburetor and includes a demonstration video that will turn the replacement process for any driver from a burdensome duty into a pleasure.

Timing marks VAZ 2109

In order for the engine to start after replacing the belt, it is necessary to install marks on the flywheel . What to do if you find a roller malfunction? In this case, it is better to replace it with another one as soon as possible. Despite the fact that it is wiser to do this in any case, so that there are no problems with the presence of a belt. If you can’t do this, try this: the nut that holds the roller is lowered using a 17mm wrench. We find a mark on the primary camshaft sprocket and connect it to the mark at the top.

How to set timing marks on a VAZ 2109? To connect the marks , remove the screw holding the camshaft sprocket, attach the marks to the crankshaft belt, and then secure it again.

Now you need to align the marks on the VAZ . To do this, locate the small elongated recess and point on the gear drive shaft. We put a drive wheel on the material for transmission. Afterwards, rotate your hands until the wheel hits all the VAZ 2108 timing marks . This is not difficult to do. The arm strength is enough to turn the pulley.

Occasionally the marks on the drive rod are not visible. After attaching the marks to the camshaft, make sure that all marks on the flywheel and housing are aligned. To do this, you must first remove the plug, after which the timing marks 2108 will become visible. If the VAZ timing marks do not match, then after replacing the crankshaft belt the engine will not rotate. Even if it starts, it will work unstable and chaotically. Therefore, try to approach this stage as responsibly as possible. Setting the marks is important for successful repair and subsequent operation of the machine.

Main stage

• After these steps, you can proceed to the main stage. First of all, you will need to remove the right engine mudguard. Sometimes it is enough to unscrew the two mudguard screws with a wrench to open access to the crankshaft pulley.
• The next step is to remove the alternator belt. To do this, you will need to unscrew the nut of the lower mounting bolt. Then you need to move the generator towards the engine and remove the belt itself.
• The third step is to remove the protective cover. The work is done using a key. The cover is secured with three bolts that will need to be unscrewed.

When the above work is completed, it will be possible to make a replacement. For successful work, you will need to align the installation marks of the part elements. If this is not done, all steps will have to be performed again.

As for replacing the timing belt on a VAZ-2108, it is performed as follows:

• Loosen the timing roller mounting nut using a 17 mm wrench. The loosened roller is turned counterclockwise to reduce belt tension.

• Remove the faulty timing belt. To do this, it is shifted from the pulley and removed from the tension roller.
• Install a new part purchased in advance. It is important to ensure that all the necessary marks match, otherwise the process will have to be repeated. After installation, you will need to tighten the belt with a nut.

To properly tension, you need to insert a key into the hole in the tension roller. After this you will need to turn it clockwise. The belt will begin to tighten and it is important to stop the action in time to avoid achieving too much force.

Once the belt is tightened, you will need to check its tension. If all actions are performed correctly, the part will rotate 90 degrees. Otherwise, you will have to loosen the tension until the required value is achieved.

The final steps to replace the belt will be:

• Tightening the tension roller nut.
• Reinstalling the crankshaft pulley.
• Fastening the timing cover.
• Wheel installation.
• Lowering the car from the jack.
• Battery connection.

Only after this will it be possible to start the engine to check the operation of the correct replacement. If the car starts without any problems, then the replacement was successful. If the malfunction does not disappear, it is recommended to seek help from a service station.

To change parts, it is worth considering that they have marks that need to be connected. For example, there may be no identification mark. In this case, for a high-quality connection of the parts, it will be necessary to install the gear shaft pulley in the center of the cut on the lower ebb of the cover.

To avoid frequent replacement of the timing belt in the engine, it is recommended to regularly inspect the vehicle. This way, it will be possible to identify a possible problem in advance and fix it much faster and cheaper.

VAZ 2108 is a car that has gained trust among domestic car enthusiasts. This model is equipped with an engine with a timing belt. If this part wears out, you can replace it yourself, and if necessary, seek the help of professionals at a service station.

In this article I will tell you in detail how to change the timing belt on a VAZ 2108 2109 2113 and 2114 with an eight-valve engine. Whether it is injection or carburetor does not matter. You will also learn about the reasons why the timing belt breaks and about little tricks that make replacing it easier.

On eight-valve VAZ 2109 1.5-liter engines, if the timing belt breaks, nothing bad will happen to the engine except replacing this belt. The valve doesn't bend!

Replacing a belt with an injection engine

The timing belt is installed only on one engine of the “nine” type - the cylinder volume is 2 liters. Using the fuel injection system did not adjust the camshaft drive chain. The procedure for replacing a part with an injection engine is very similar to the replacement process for a carburetor car engine.

The difference lies in several factors. You will need to do the following:

• Remove the crankshaft position sensor located next to the pulley from the engine. During disassembly, remove the plug from the socket, and then loosen the sensor mounting bolt. Then remove the sensor from the hole.
• To loosen the nut, unscrew the M13 nut located on the generator.

There are also some differences when reassembling:

• The drive wheel for transmission must be set as level as possible. To do this, it is necessary to install the upper mark of the first cylinder on the flywheel and metal housing.
• In this case, the nameplate of the gear must exactly match the gap on the nameplate. The installed drive wheel must be in front of the sensor.
• Pay attention to the gap. The gap between the parts should be no more than one millimeter.
• Once assembly is complete, start and test the engine.

Dismantling

To correctly replace the timing belt, you first need to dismantle the element. The process can take quite a lot of time, although the work itself is not very difficult.

1. Remove the casing covering the belt, pulleys, dismantle the tension roller and other elements related to the gas distribution mechanism.
2. The cover is held in place by three mounting bolts, so removal should not be a problem.
3. Remove the alternator belt. This will give you access to the desired object - the timing belt. To do this, lower the retaining bolt down a little and move the generator towards the engine. This will loosen the belt, making it easy to remove.
4. Align the gas distribution mechanism to the marks. First you need to install the crankshaft in the required position. This is done by turning it and looking through the hatch on the clutch housing.
5. Stop rotating as soon as the mark on the crankshaft flywheel aligns with the marks on the housing. This indicates that the piston of the first cylinder is at TDC - top dead center.
6. Make sure that the mark on the camshaft gear is aligned with the mark on the metal housing.
7. Having set the marks, you can begin the procedure of dismantling the old worn timing belt.
8. Release and move the tension roller to the side. This will release the tension on the strap. As a result, it can be removed from its position.
9. Next you need to remove the belt from the crankshaft gear. To do this, the pulley is first removed.
10. There should be no problems with dismantling the pulley, since it is removed this way. First remove the right wheel, turn the steering wheel to the right and you will gain access to the side shield. The shield is removed, and behind it is the crankshaft pulley. Relevant for carburetors and injectors.
11. If your VAZ 2109 has an injection engine, you will need to fix the crankshaft to remove the pulley. It is not difficult to do such a procedure. Insert a long screwdriver into the special hatch where the flywheel mark is located. This will lock the crankshaft in the required position, so you can easily unscrew your pulley.
12. On a carburetor VAZ 2109, fixation should be performed directly on the pulley.
13. Before you begin removing the timing belt, examine the condition of the water pump and tension pulley. You should also check whether the axis of the tension roller and timing gear are in good condition.
14. If there is damage, defective elements must be replaced.
15. Check the current condition of the camshaft and crankshaft seals.

Experts agree that when replacing the timing belt, the rollers and pump should also be replaced. But this is a recommendation, not a requirement.

Replacing the roller

Replacing rollers or other drive belt parts is very easy to do. The work does not require the use of special tools. Follow the step by step instructions:

• Remove the terminal from the battery to disconnect the vehicle from power.
• To prevent accidental rotation of the crankshaft, use installation tools.
• We unscrew the bolt that changes the tension, loosen and remove the belt.
• Remove the part (if there is a fastener, unscrew it).
• Replace damaged parts and fold the mechanism in reverse order.

Replacement features

The operation is not a complicated process, but requires care and concentration, since mistakes can lead to a major overhaul of the power unit. The car is placed on a level area. Wheel chocks should be installed under the wheels to prevent the machine from rolling away.

Replacing the timing belt on a VAZ 2108 engine is done as follows:

1. It is necessary to remove the drive protection and the generator drive belt from the crankshaft pulley.
2. You should unscrew the pulley bolt, remove it and return the bolt.
3. It is necessary to remove the rubber plug from the clutch housing hatch. Next, rotate the crankshaft until the mark on the crankshaft flywheel aligns.
4. The matching of the installation marks is checked.
5. Loosen the tension roller fastenings and remove the timing belt in the following sequence: From the camshaft pulley.
6. From the video.
7. From the pump pulley.
8. From the crankshaft pulley.

Note! When the timing belt is removed, do not rotate the crankshaft, because This can lead to bent valves and costly engine repairs.

Installing a new timing belt

The crucial moment has arrived. If the camshaft and crankshaft markings match, a new timing belt must be installed. If there are markings or writing on the belt, they should be in a clockwise direction, and if they are attached to a belt, the hand should be oriented as well. Before doing this, remove the old belt. If it is intact, check it. If you see that it is cracked, it is dangerous to carry out replacement work.

The belt is first installed on the crankshaft gear and then, with a little force, installed on the camshaft sprocket. When installing, wind the drive sprocket and tighten the roller with a saw.

Checking the timing belt tension is done by adjusting the tension roller.

But, there is an easier way to install a new belt. To install a new belt, follow these steps:

• Install the new tensioner in the desired position.
• Move the belt through the gears. If it is necessary to change the position, this can be done by turning the drive shaft clockwise.
• Rotate the roller until the belt is properly tensioned.
• Tighten the roller.

When replacement is required

The timing belt is responsible for the operation of the gas distribution mechanism.

Try in every possible way to avoid breaking the belt while driving, otherwise this may negatively affect the condition of the engine and the cost of its repair.

The most dangerous is the contact, the “meeting” between two main elements - the piston and the valve. In this case, the unit becomes deformed, requiring expensive restoration of the car.

There are several main criteria that indicate the need to replace the unit.

Why does the belt break?

Make sure that the belt is installed straight. Due to distortions, the belt is prematurely damaged and breaks. One of the reasons may be bearing failure. If a breakdown is detected, the bearings must be replaced, as there is a risk of coolant leakage and belt breakage.

How to tighten the timing belt of a VAZ 2109

To tighten the belt securely, turn the tension roller using a wrench. When the belt is installed correctly, the branch should rotate ninety degrees.

If you overtighten the belt, you will find overload on the bearings and other parts. Too much pressure is harmful to the belt, which may break during physical activity.

What you need to know

There are a number of signs indicating that it is time to change the timing belt on VAZ cars:

• black exhaust gases;
• uncharacteristic engine vibration during operation;
• difficult starting of the power plant;
• the appearance of noise in the motor.

If you replace a part, you must also change the roller. The pump requires mandatory diagnostics, as it rarely lasts more than 90,000 kilometers. These procedures can be classified as scheduled repairs.

If the belt breaks, the pump or pulley jams, then restoration work becomes unscheduled. To reduce the risk of such troubles, it is recommended to change the belt and its components more often - once every 35,000-40,000 kilometers.

How to set the timing belt on a VAZ 2109 video

After this, the protective timing belt is installed, for which it must be installed on the seat and the three bolts must be tightened again. Reinstall the air intake and secure it with the clamp. The metal and plastic guards are installed in place, the wheels are removed, and the vehicle is lifted off the jack. Then you can start the engine. It will start without problems, and its operation should be stable, without differences or insignificant sounds. This is only possible if all symbols match and the seat belt is tightened with sufficient force.

Experience shows that replacing VAZ 21099 and 2109 timing belts can be done independently, without the need for professional personnel at a service station, especially if it is a planned replacement and the belt is intact before replacement. You don't need any special tools, you just need a socket set with a door and keys, and a regular flathead screwdriver can do the job on its own.

If you are a beginner, replacing a VAZ timing belt can be a daunting task. We suggest watching a short video that explains in detail how to install the timing belt on a VAZ 2109.

Replacement (preparatory stage)

Before setting timing marks on the VAZ-2109, you need to remove the old belt and install a new one. To do this you need to perform partial disassembly:

1. Loosen the bolts on the wheels and jack up the right side of the car.
2. Remove the wheel.
3. Remove the protective plastic casing. It is necessary to unscrew the three bolts that secure the part to the block.
4. Remove the alternator belt. To do this, loosen the upper nut located on the bracket. Next, the generator moves towards the motor, this weakens the belt tension, thanks to which the latter can be removed without much effort.
5. Remove the generator pulley.
