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 timing belt vaz 2109 you can do it yourself, without turning to specialists for help. In this article we have collected complete information. Soon you will see that VAZ 2109 timing belt replacement It happens simply 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.
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.
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.
- Remove the casing covering the belt, pulleys, dismantle the tension roller and other elements related to the gas distribution mechanism.
- The cover is held in place by three mounting bolts, so removal should not be a problem.
- 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.
- 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.
- 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.
- Make sure that the mark on the camshaft gear is aligned with the mark on the metal housing.
- Having set the marks, you can begin the procedure of dismantling the old worn timing belt.
- 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.
- Next you need to remove the belt from the crankshaft gear. To do this, the pulley is first removed.
- 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.
- 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.
- On a carburetor VAZ 2109, fixation should be performed directly on the pulley.
- 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.
- If there is damage, defective elements must be replaced.
- Check the current condition of the camshaft and crankshaft seals.
Crack on the strap
Experts agree that when replacing the timing belt, the rollers and pump should also be replaced. But this is a recommendation, not a requirement.
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.
What's the result?
As you can see, a broken timing belt while the engine is running is usually the reason for subsequent major engine repairs (valves hit the pistons and bend, a piston defect occurs, etc.).
Finally, we note that when replacing, it is important to correctly align the timing belt according to the marks, as well as achieve the desired tension. Otherwise, a loose belt may slip on the teeth. If it is overtightened, then a breakage may occur, which greatly increases wear on the belt, pulleys, rollers, etc.

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.
Adjustment
If you have identified a problem with out-of-phase phases, then you just need to find out how to set the ignition on a Ural motorcycle. This will make your life much easier in the future. Please note that the electronic ignition on the Ural motorcycle is regulated completely differently.
So, you need to adjust the ignition of the Ural motorcycle. To work, you will need wrenches, a screwdriver, and it is advisable to take a test light. Adjustments are made in the following order:
Izh Jupiter 5 ignition adjustment is done in approximately the same way. Now you know how to configure this system on your motorcycle.
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.
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.
Begin
Everything we need.
We unscrew the three ten bolts securing the protective timing cover and remove it.
Next, loosen the nut thirteen that secure the generator and unscrew the tension bolt ten.
We take the generator to the engine and remove the belt.
Remove the engine protection and drain the antifreeze. We set the camshaft mark by turning the crankshaft clockwise. The ebb on the pulley should be opposite the bend of the protective cover fastening.
Unscrew the crankshaft pulley mounting bolt. We put the assistant in the cabin and force him to engage fifth gear and press the brake. And at this time we easily and naturally unscrew the bolt using a 19 meter head and a pipe of one and a half meters. It must be screwed properly, and some craftsmen lubricate it with sealant and then wait for kind words addressed to them.
On the left side we see the crankshaft position sensor. We will need it to subsequently check the correct installation of the timing belt. We remove the crankshaft pulley and see that the marks match.
Unscrew the nut on the tension roller 17 and remove it along with the belt. Then unscrew the camshaft pulley bolt and remove the last one. Be careful not to lose the key. We unscrew everything that secures the protective metal shield, namely one ten-point nut and a bolt securing the cover, three bolts securing the pump.
Remove the protective cover and pump. Antifreeze remaining in the block may leak out if you have not drained it. Carefully, it's sweet.
We clean all the parts from oil and belt residues, as well as the pump seat from the old gasket and sealant.
Lubricate the gasket of the new pump with sealant and put it in place. We install the metal protection and tighten all the bolts and nuts securing it. We tighten the pump bolts evenly in a circle, then check whether the pump is spinning. Recently a client brought in an original pump, which turned out to have slightly larger petals and after installation it began to bite. I had to modify it with a grinder and take measurements several times. These are the spare parts we have.
We check if the key is lost on the camshaft and install the pulley. We tighten its bolt to seventeen.
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.

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.
