How to change the drive belt. All you need to know the motorist about the replacement of the belt and the timing chains how to put the drive belt

The drive belt of the auxiliary units must be replaced when cracks, breaks, and rubber discontinuisions from the tissue base are detected. Forcibly, regardless of the condition, replacing the belt every 60 thousand km of mileage.

There are three variants of the recruitment schemes of the auxiliary units, depending on the configuration of the car Renault Logan / Sandero of the first generation.

If you are the owner of a modern washing machine with a direct drive, then you have no need to worry about the flying drive belt, because it is simply not in your washer. If your washing machine is a collector or asynchronous engine, and the pulley of the drum rotates through a belt drive, then this publication is for you. On its pages you can get information about eliminating the fault associated with the belt of the washing machine.

How to determine the breakdown?

The average man is usually difficult to determine what happened with a washing machine, because if the drive belt flies, the home helper cannot continue washing. The drive belt is located in the housing of the washing machine and see what he flew, there is no possibility, but to understand for some signs that it happened quite possible.

Most often, the washing machine itself notifies the user about the breakdown and its character through the built-in self-diagnostic system. Thanks to this system, the car does not cost anything at the same second to respond to the breakdown, stop the operation of all systems and give an error with a specific code on the display.

The error code depends on the brand and model of the washing machine, so the user's task when such an error appears to view the error codes table for a specific "home assistant". Having such a table in the hands, you can easily decipher the error code that is displayed on the display of your washing. You can take such information, in particular, on the pages of our site. In a number of publications, we have deciphered almost all the error codes of most of the models of washing machines, so there will be no problems with searching for information.

It happens that the washing machine does not give the error code, but the breakdown still takes place. In this case, the fact that the belt flew and needs to be applied, is confirmed by a number of indirect signs.

• The washing program starts, the engine works, but the drum does not rotate;
• The engine of the washing machine is evenly buzzing, and then "silent" with equal time intervals;
• The program starts, the engine begins to work continuously, after which the electronics hangs.
• The drum of the washing machine rotates manually very easily, while this rotation does not cause even the slightest noise of the engine.

If any of the above features is evident - this is a good reason to turn off the washing machine, remove the rear wall and take a look at the drive belt.

Eliminate breakdown

The problem lies in the fact that the flewless belt is only a consequence of any more serious problem. If the belt on your washing machine flew first time and this is a single case, then you just need to wear it back. Make it does not always happen simply, but not because it is any complex repair, but because it requires a skill, and sometimes short physical strength. In general, the procedure for holding work looks like this.

In some cases, remove the rear wall of the washing machine does not give its upper cover. Then it is necessary to first remove the top cover, and then remove the rear wall.

If the breakdown is repeated

Much of more serious problems can turn into a multiple flying of the drive belt. If the belt flew in half a year at least a couple of times it already should alert you, because it is almost certainly a consequence of a more serious breakage. What are the reasons for frequent flux of the belt from the engine pulleys and the drum?

In the case when the bearing of the washing machine, flying the belt, is the smaller of the victims of the waiting for your technique and you.

We buy a new detail

Washing belt must be replaced, you will not argue with this statement. But then another question arises: how to buy a suitable spare part? The best option, take the old belt and go with him to the store, show the spoiled to save and ask to bring similar new.

Unfortunately not always and not all this option is available. If you are, for example, a resident of a remote village, where the only store is local Selpo, then for you the most acceptable option there will be an order of spare parts over the Internet and delivery by its mail to the district center or right in the village, but it is easier to say than to do. How, in this case, order the right belt?

There are two main types of drive belts: wedge and polyclinic. If your washing is an asynchronous engine, most likely the case will have to have with a wedge belt. If the collector engine, then it means you have a polyclinic belt. Having understood with the overall theory of drive belts, we begin to carefully read the inscription, drawn on the old belt. The first digits (usually 4) denote the length of the details in millimeters, then the letter comes in the figures indicating the shape of the wedges. The letter is coming a digit that defines the number of wedges.

All numbers and letters need to rewrite and when ordering details be sure to take into account this information.

New belt for its washing machine You will be customized with the: Models of the washing, information on the belt, the material from which the belt is made. Taking into account all the data, you never go wrong when ordering.

Summing up, we note if the problem lies only in the separated drive belt of the washing machine, it is possible to eliminate this breakdown with your own hands, in some case, even without difficulty. But if the constantly flourishing belt is a consequence of a more serious breakage, here without the help of an experienced wizard can not do. Good repair!

When breakdown of the gas distribution mechanism of the Lada car, the launch of the motor and the full operation of the machine will be impossible. To prevent such trouble, you need to follow the state of all device nodes, including timely changing the timing belt on Lada Grant.

[Hide]

When and how much should you change?

According to the official regulations, the belt engine 21116 or 11186 changes with a mileage of 60 thousand kilometers. In fact, many car owners produce repairs and change the strap of the gas distribution mechanism, as well as the roller of the tensioner, Usually after 50 thousand km run. The norm for checking the condition of the product is every 15 thousand kilometers.

What signs indicate the need to replace:

1. Wear strap structure. As a result of wear, the product will slip on the pulleys and ultimately turns. This usually happens with an increased load or high humidity. Slices of thread and tissue residues can be observed at the worn belt.
2. In most cases, rapid wear of the product is due to the deviation of the position of the tensioner or pulley. The strap will fail if the operating temperature of the bearing device is increased or the part functions incorrectly.
3. The appearance of cracks or detachments on the structure.
4. The working side of the belt has become less elastic and more solid. With such a problem, the strap can glitter. Due to increased hardness, the product will not be able to contact the camshaft with a pulley.
5. Increase the length of the belt. If the size of the product is greater, it must be changed. Reducing the elastic characteristics of the strap will result in its rapid cliff.
6. Deviation of the position of the product from the normalized indicators. Such a problem says that you need to change the roller of the tensioner.

Crack on the strap structure

Causes of rapid wear

Why the timing belt on Lada Grant is wear out:

1. Poor quality of the material from which the strap is made. Many producers save on raw materials, which leads to premature product cliff.
2. Low quality assembly of nodes and mechanisms of the power unit through which the timing strap passes.
3. The exploitation of the belt, which began to wear out. When there are traces of damage on its structure, the belt must be changed, and not continue to use.
4. Errors made during installation. In the case when the belt is incorrectly delivered and loosely lay down on the rollers and pulleys, it is extended much faster.
5. The failure of the tensioner roller. If you do not change this item when installing a new strap, it can be extended faster, which will also lead to the cliff of the product.

You can learn about the consequences of the Lada Grant belt break from the roller shot by Denis Gorban.

Belle selection

Now we will analyze what better to choose the timing strap VAZ 2114 eight or sixteen valves.

To buy a good product that can be installed and tighten on the drive of the gas distribution mechanism is not easy. After all, the desired strap should be high quality.

Today, consumers are offered several decent products from manufacturers:

1. CONTECH ANTRIEBSSYSTEME GMBH. On the original packaging of the belt there is a sticker with a QR code. Included you can find a label where the date of shift is noted, the mileage of the vehicle and the information about the nodes that were changed at one time. When repairing, installing, tensioning the belt, as well as replacing the rollers, you can specify all the information on paper and, if necessary, see when and what exactly changed for the last time. On the strap itself you will see the designation of the brand and the party number.
2. Gates 5670xs. On the packaging of the original product there is a QR code, as well as a hologram, designed to protect against fake goods. The sequence number is applied to the outside of the strap. Included with the product there is a sticker on which you can specify the belt number and the date when it has been replaced.
3. Trially GD 790. Italian-made goods are implemented in our market in the form of a remklectage with a tensioner roller. The product is packaged in a cardboard box with a plastic insert inside. The set of this belt also includes a sticker with a vehicle mileage and a dates of changing the part. Here you will see a warranty card. The manufacturer took care and added detailed instructions for replacing.

How to replace with your own hands?

Replace the strap on 8 or 16 valve freight grant in the garage conditions or per service station. To prevent errors and make everything right with your own hands, follow the actions specified in the instructions.

Required tools

Before proceeding with the implementation of the task, prepare the following:

• set of wrench, you will need tools for 10 and 17;
• special tool for stretching the roller, the device can be bought in the auto shop;
• jack;
• set of stars;
• forceps.

Dmitry Berbrar canal provided a video, which shows the consequences of the timing strap cliff.

Step-by-step instruction

How to install and pull the product correctly:

1. Talk the car into the garage, open the hood and loosen the bolt wrench fastening the battery terminal. Contact disconnected.
2. Dismantling the generator set drive strap. To replace the timing belt, you will need to provide access to aggregate components and mechanisms. Remove the front right wheel. Loosen the balloon key bolts on the wheel, unscrew them, then dismantle the wheel by putting the front of the car to the jack.
3. Unscrew the bolts fixing the upper vehicle belt cover. The plastic cover is used as protection, dismantle it. After that, set the first piston of the car power unit to the top of the dead point.
4. The next step adjust the nut of the tensioner roller. Proper configuration of this element provides a high battery life. To disassemble the drive belt, unscrew the roller nut key, it will deploy the product. After completing the task, you can start removal. Remove the belt, cutting it without twisting the screws, will not work. Videos in any case will have to unscrew to install a new strap in the future.
5. Remove the main screw of the pulley generator mechanism, use a wrench for this. When, in the dismantling process, difficulties arose and the bolt does not come out of the shaft, remove the plug located in the car clutch crankcase. If you have a mounting blade, it must be fixed to the flywheel's cloves. If necessary, you can use a long screwdriver. This will prevent the generator pulley screw scrolling, since the crankshaft is fixed by the tool.
6. Remove the generator shaft. This procedure is performed after the blade is extracted. When the pulley is removed, it must be put down to the pure surface. Make sure that the dirt does not stick to it, otherwise it can cause a jam.
7. The next step will be dismantled by the lower part of the drive of the gas distribution mechanism. To do this, unscrew three locking screws. Set the drive to the side.
8. Then the strap is removed - first from the distribution, and then from the crankshaft. When dismantling, appreciate the condition of the roller. If it was worn out or in the mechanism there is a big gap, it must be replaced. Experts recommend doing it during each belt change. With further installation, the strap must be stretched first onto the crankshaft, and then the camshaft pulley. It is important to observe the power of the stretch. If the belt is too stretched, it will lead to its rapid wear, as in the case of it is weakened. The details assembly procedure is carried out in the reverse order.

The cost of the belt of production Continental on average is 800 rubles. The Gates product will cost the consumer about 1100 rubles. This option among car owners is considered optimal and reliable. You can buy a trially belt, its cost is about 1900 rubles, but the equipment includes not only the strap, but also the tensioning roller.

Consequences of the timing belt

If the vehicle is equipped with an engine 11183-50, then when the belt is broken, the consequences will be unrigible - the unit will stop starting and you will not be able to use the car.

When the cliff occurs on another engine, the problems will be serious:

1. When cutting camshaft will remain in the position at which it worked at the time of damage. At the same time, the crankshaft will continue to move.
2. This will lead to the fact that the pistons will be with high strength to beat the valves of the engine, which during the breakage were in the open position.
3. As a result of the strikes, these elements are brought upon, damage to the piston itself is possible. With such a problem, the car owner will have to carry out overhaul of the power unit.

According to the instructions of the generator belt on Ford Focus 2 is not removed with the weakening of the tensioner or the generator, and it is cut, and to install it a special set of fixtures will be required. which are applied depending on which pulley (generator, gur or air conditioner) dresses the drive belt. On motors 1.4 and 1.6 liters. FF2 tension rollers on the belts of the attachment of attachments are not, but at 1.8 and 2.0, although there is a tension roller on the generator belt, but the belt technology is still disposable and simply cut offAnd new ones are installed, too, with a special safety. Since many have no such equipment, and on his purchase it is a pity for money, there are other ways as possible or FF2 generator without fixtures. We will talk about some of them, and also show visual on the video. As a temporary measure, you can use a special means - with which you can resolve the scrolling of the drive belt and slightly increase the coupling characteristic.

Official Independent Replacing the focus generator belt on a 1.6 liter engine is not recommended because rough and inept handling can damage the belt during installation, But on the engines 1.8, 2.0 you can cope and yourself, it will be simpler there.

To replace the Ford Focus 2 1.6 drive belt with air conditioning, you need a set of belts - 1708273 His composition:

• generator belt;
• air conditioner belt;
• fixtures for installation (3 pieces).

If you do not originate, you can buy CONTITECH 6PK1059ELASTT2, will cost dollars 15 cheaper.

A set of fixtures: 1 - to drive auxiliary units (generator, gur, pump); 2 - air conditioner compressor belt

Replacing mounted belts on focus 2 1.6

To change the generator belt, the device from two parts is mounted on the pump wheel (install the device before clicking when it becomes as necessary). Pump pulley turns on a special bolt (turnkey on the "19") on the device. The belt starts in such a sequence: first we wear the gur for the pulley, while the strap starts under the device on the pump, then we throw the belt to the generator.

And to replace the air conditioner compressor belt, we take another fixture and put it on the crankshaft pulley by throwing the drive belt to the compressor and the dressing of it from below to fit. Then rotate for a bolt of a KV key (on "18") we turn the pulley clockwise, and the belt hold the hand to do not jump.

Replacing the generator and air conditioning belt on FF2 1.8 and 2.0

Now consider independent replacement of the air conditioner belt and the generator on focus 2 with motors of 1.8 and 2.0 liters, where you can do without a priblud, with saving to buy a set, and taking the belts of the company Gates:

• 6pk1305 - the ff2 generator belt;
• 5PK705SF - air conditioner belt.

To get to the belts, as in the previous case, it will be necessary to remove the decorative cover of the motor, the front right wheel, and behind it the mudguard and the liner (T25 key), and then you can act in several ways:

Option 1 Replacement of the air conditioner belt

• we unscrew the five air conditioning compressor bolts;
• fix the condition, in order not to break the hoses;
• remove / put the drive belt;
• finish back the compressor, but there is one but. When the old belt is put back, the compressor will turn out to be screwed into place without problems, and if the new, not stretched, strap, it may be so smooth and will not work.

Option number 2 How to change the compressor drive belt

• without unscrewing the compressor, remove it with a pulley;
• head to "10" unscrew and remove the pulley clamping plate;
• we will remove the pulley lock ring, and then the pulley with the belt;
• open a new hinged belt on the pulleys of the KV and the compressor;
• we will select the tube suitable in diameter (so that the diameter is more compressor shaft, but less than the hole in the pulley);
• we skip the tube through the pulley and wear the compressor to the shaft of about 5 mm and press down slightly down, the pulley under the action of the resistance of the belt hits the shaft itself;
• we collect everything back.

At the top of the engine, to change the cross-belt of the generator, unscrew the 2 tensioner bolts and leave it on the hairpin, take it into the right side of the machine, remove the strap!

Assembly in reverse sequence. Thus, on the replacement of ff2 hinged belts without a priblud, it will take about an hour of time.

Replacing Drive Belt Ford Focus 2 1.8 TDCI

Replacing the generator belt on Ford Focus 2 1.8 Flexifuel

The main purpose of this part is the transfer of torque from the camshaft to the car crankshaft. It provides synchronous rotation, which is so important for the optimal work of the entire gas distribution mechanism.

Control and normal belt work is very important for automotive engines, which are pistons with valves in one block. Despite the fact that the valves are in one place with pistons, these details are not found just due to the timing belt. As soon as the belt breaks, it begins to fight into an open valve, gradually bending it, as well as the clinite piston. If you do not replace, the engine will require major repair work.

Reasons for the failure of the timing belt

The reason for the exit of the belt failure can be not only wear. Situations are quite often found when and a completely new belt for a relatively short time wear out and rifles. There may be several reasons for this.

1. In most cases, the cause for rapid wear belt is a pump. It contains bearings and not in the center of pulley, but a little shifted to the side. It is their wear through a certain time that leads to the doss of the pump axis, which automatically causes the pulley pumping, and the subsequent sliding of the timing belt. Also, the reason can be the installation of a new pump. If the place was originally not very well protected, if there are small dirt remnants or lubrication, it can lead to essential displacements.
2. Serious worn out of the guide and tensioning roller.
3. The leakage of the machine oil from the junction of the camshaft.
4. Wear teeth, caused by gear of the crankshaft and distributional shafts. A sign of such a problem is the appearance of penetrating teeth on the belt.

The most common cause of belt wear is a strong tightening of the mechanism or its weakening. It often occurs after self-replacement details. It is for this reason that it is so important to know not only after how much to change the timing belt, but also how to do this correctly if it is planned to appeal to the car service.

Service life and frequency replacement of the timing belt

Many drivers are interested in the frequency of replacing the timing belt. This process directly depends on the wear of the part, on the operating time of the vehicle.

Each car in the instructions have mileage, after which you need to replace. Periodicity directly depends on the car brand. If this is a foreign car, 120 thousand km should pass before replacement, the Russian auto run is 60 thousand.

I deciding whether to change the timing belt, you should not wait for a complete run, it is desirable to carry out this process, using the established norm of about 15%. If the time of extreme replacement is unknown, you need from time to time to check the item for wear.

Procedure for changing the timing belt

Quite often you can find full-fledged sets for replacement, which includes a belt with rollers. Labor and temporal costs of replacing every part are about the same, but since it is not always possible to understand the level of wear of each, it is reasonable to replace everything at the same time.

Required tools for replacing the timing belt

Before replacing, you must prepare special tools. Among the most important of them can be noted:

• hexagon "Five";
• a set of horn keys;
• cylinder key;
• special adjustment key for tensioner roller;
• jack;
• large screwdriver, and mounting is also suitable.

Preparatory work can be attributed not only to prepare instruments, but also certain manipulations with the car itself. The machine is put on a flat surface and is fixed with special stops under the wheels. Be sure to tighten the handbrake, raise the hood, disconnect the minus battery terminal, and remove the engine cover.

Let's, we will analyze the process itself, how the timing belt is replaced.

Removing the belt timber

Before installing a new belt, you must remove worn. For this, the following sequence of actions is performed:

1. The generator belt is removed. In some situations, to get to the timing belt, it is required to remove the polyclinic belt. All nuts are weakened, if necessary, you need to push the generator to eliminate tension and subsequent belt removal.
2. To gain access to the belt, such additional details are removed as the enhanced steering pump, compressor, generator. It does not need to remove fittings under the pressure of the compressor. It's just enough to unscrew them and move a little to the side, without affecting the pressure of the entire system.
3. If there is a distributor cover, it must be removed. For this purpose, you will need to open the locks and remove the fastening screws.
4. Alignment of the main installation labels. By means of an end or wrench for a crankshaft bolt, the engine must be turned until the pulley label coincides with the zero mark. At this stage, you need to check that the distributor rotor coincides with the pointer present on the distributor housing. This is a kind of message that the rotor is ready for the ignition of the cylinder. If there is no such coincidence, you will need to perform another full-fledged turnover.
5. It is important to check the need to remove the vibration pulley pulley, which may be required to remove the drive belt cover. Very often, the lid overlaps some part of the crankshaft, and the pulley does not give it off. When reverse assembly, you will need to return some additional seal.
6. Bolts and screws are unscrewed, which hold the timing belt cover, and it is removed from the engine. All components and belts of the auxiliary units are removed here, which may interfere with the removal of the lid. The list of such components directly depends on the vehicle model, because in this case it is worth using a special service guide.
7. The accuracy of combining the installation labels of the distribution and crankshaft is checked. The bulk of the engines has a special dotted line on the pulleys. It must be aligned by a special label on the block or on the cylinder head. If the old belt was torn, it is worth considering the tags more carefully, relying on the official leadership of the car.
8. Removal of the worn belt is removed.

Completing the removal process, it is worth considering the zone for the presence of traces of oil leakage. It is required to inspect the sections next to the seals of the crankshaft and the camshaft, as well as the pallet and the valve cover.

All detected leaks need to be eliminated before installing a new part.

It is equally important before installing a new belt to weaken the main tensioning device. Here it is enough just to loosen the fastening bolts a little, you do not need to remove them completely. After weakening, the obtained state must be fixed in a weakened position.

The suspension device itself must be checked for the presence of dents or cracks. It is very important to turn it out and listen: if there is some rockness or cod, which may indicate the weakening and wear of bearings. When signs of damage or bearings are detected, it will be necessary to replace the pulley of the tensioner. This is a fairly common operation, as the pulley can dry, relax, crack, wear and frozen.

Installing a belt timing

In the process of installing a new timing belt, it must be unpaved, remove the item from the stars. If the belt was used for a very long time, it can get stuck in pulley grooves. In this case, it will be necessary to pushing it with a screwdriver.

The new belt is tensioning in full compliance with the instructions and the specifics of each car separately. Special attention is paid to information in the tightening manual. The crankshaft pulley fastening bolt must have a high normative torque.

If there is a hydraulic tensioner in the vehicle, disassembly may be required to insert the piston back to the cylinder. It is necessary to insert a new belt into the clamping device and compress until all the holes do not match and will not be allowed to insert the holding rod. After inserting the rod, you can re-install the automotive tensioner.

Tagging and tension adjustment

Simultaneously with the new belt, the crankshaft is installed on the place, the camshaft gears, as well as pumps. Everything is securely fixed, and the belt itself is stretched through its rotation along the clockwise arrow. The belt tension level is easy to check manually. It is enough just to try to turn it with your fingers. If the belt is well stretched, it will turn out to turn no more than 90 degrees.

After that, all fixing and rotating tools are extracted. With the help of the crankshaft, two turns are carried out.

All labels are carefully checked on the gears. Once everything is installed accurately and competently, you can start the installation of all the remaining items. There is a solution to the question of how to change the timing belt, can be considered complete.

Features of the belt installation for 16-valve engines

Separately, it is worth studying the question of how to replace the timing belt for sixteen valve engines. Performing a belt measurement on a 16-valve engine is distinguished by the fact that it will be necessary to use two special fixing devices. They can be purchased in the autoinstrument store or make it yourself.

The main difficulty of replacing the timing belt on such two-level motor installations is the string of camshaft and the crankshaft in a certain position. Clamps are needed for this.

Replace without using these devices will be quite risky. In the case of incorrectly assembly, you will have to change a large number of details, which will be in a significant amount.

Selecting a belt timber

The belt in the gas distribution mechanism plays a very important role, in the process of work it is constantly subjected to dynamic loads. For this reason, special attention is paid to the quality of this component. To purchase a durable and reliable belt, it is worth paying attention to the manufacturer. Among the most main brands that need to be preferred can be noted as follows:

• CONTITECH;
• Gates;
• Dayco;
• Bosch.
