Tension roller Grant 8 valve. Specificity timing on the Lade Grant. Getting to work

The gas distribution mechanism is one of the most important engine systems. internal combustion. The GDM manages the engine valves, performing the normal functioning of the intake and release. During inlet, the fuel and air mixture enters the combustion chambers as a result of the opening inlet valve. The next phase opens the release valve, and the gas distribution mechanism displays spent gases from the combustion chamber. A standard gas distribution unit is used on the VAZ 2190, which differs only by the number of engine valves.

Characteristics of TGR Lada Grants

The Lada Granta Gas Distribution Mechanism has a belt drive. Such a device is familiar to car enthusiasts for a long time. After all, the design of the timing was moving from the VAZ 2108 engine, which became the basis for all subsequent modifications power plants VAZ. Two types of engines are installed on the grant: 8-valve and motor on 16 valves. 16-valve gas distribution system power aggregate It has a complex device and enlarged dimensions compared to the 8-valve. Accordingly, the replacement of the timing belt grants is complicated.

The main feature of the 16-valve device in the presence of two camshafts operating synchronously, in parallel with the crankshaft. The design is in the head of the cylinder block. All three shafts are synchronized by means of a belt with gear drives. The main drawback of the timing belt is in the unreliability of the belt itself. During its cliff or when leaving the valves are encountered with pistons and bend. Vividly the structure of the 16-valve GDM is represented in the photo.

The timing kit can be changed with their own hands. The main thing is to know about the presence and correctness of the placement of installation labels. By the way, most of the cars are devoid of such labels, so in this case Advantage for VAZ cars.

The eight-smelled drive of the timing of Lada grants, compared with the previous vehicles, it looks easier. The scheme is simple, because there is no flood roller and there is only one camshaft. Vitely the timing of the timing of 8 valves can be viewed in the photo.

If doubts arise in own power, I do not need to try to replace the timing belt with your own hands, as you can harm even more. In addition, in the car service, such a procedure performed on the 8-valve engine is inexpensive. But in the case of a motor at 16 valves, the price tag is usually much higher.

Replacing the timing belt on the 16-valve engine grants

Access to the drive of the gas distribution device is closed with a plastic casing. To remove the cover, you need to unscrew the five screws with a hex key on 5. Pay special attention On the location of these screws. On the photo, the number 1 shows the fastener screws of the upper cover, and the number 2 are screws of the fastening of the bottom cover. After unscrewing the five screws, the top cover should be lifted and removed from the engine.

If the car has mechanical PPC, you need to turn on the fifth speed, squeeze the right front wheel And turn it clockwise. At the same time, it is required to inspect the belt for cracks, sweepers, bundles, etc. If the car is equipped with an automatic gearbox, you need to remove the right front wheel and the boot (protective shield) on the right. Head at 17 rotates a drive pulley attachment bolt for additional equipment (Air conditioning, generator) and the belt is examined. If various defects and damage to the belt are diagnosed, it must be replaced urgently. The replacement will also be required in the case of cell heights, a malfunction of a water pump and a tensioner roller.

On the 16-valve motor, the belt transmission will lead to a discrepancy between the angular arrangement of the crankshaft and camshafts. As a result, the piston group with valves will occur. As a result, repair work will be required.

We post the right front wheel and turn on the fifth gear in the gearbox. Rotating the wheel clockwise, we turn the engine crankshaft and inspect the timing belt. With normal belt tension ...

The surface of the toothed part of the belt should not have folds, cracks, fermented feeds and tipping tissue from rubber. back side The belt should not have wear, exposing Cord's threads, and maritime traces. On the end surfaces of the belt there should be no bundles and grinding. When defects are detected on a belt or significant mismatch of the belt tension control elements (see photo above) the belt must be replaced. You should also change the belt to the new one when traces are detected on it motor oil (Before mounting a new belt, the cause of the belt on the belt should be eliminated) or when replacing the coolant pump.

Attention! The failure of the timing belt (breaking and cutting of teeth) can lead to the styling of the valves into the pistons due to the mismatch of the corners of the rotation of the crankshaft and the distributional shafts and, as a result, to expensive engine repair.

Replace the timing belt in accordance with the maintenance regulations, we carry out every 75 thousand km of mileage or in case of detection on the belt of defects.

Next, we should dismantle the generator drive belt or the drive belt of the auxiliary aggregates.

To avoid damage to the position sensor crankshaft It is necessary to remove it.

Before dismantling the belt, it is necessary to check the engine gas distribution phases - set the piston of the 1st cylinder to the NMT position (upper dead point) of the compression tact.

Before turning around the bolt fixing the pulley of the generator drive ...

Head "on 17" turn the bolt for fastening the pulley drive of the generator, ..

In this case, the tensioning roller will turn the belt tension to weaken. Remove the timing belt from the pulleys of the crankshaft and distribution shafts.

Attention! After removing the timing belt, it is impossible to turn the crankshaft and distributional trees In order to avoid stitching pistons in the valves.

To remove the belt tension roller turn the bolt of its attachment ...

The roller must rotate silently, evenly without jamming. Otherwise, the roller must be replaced. At the same time, you can check the health of the coolant pump, twisting and shocked for the pulley. We set the tension roller into place, finally without tightening the bolt of its attachments. For different modifications The engine in the head of the cylinder block is made by two threaded holes for a tension roller mounting bolt.

We establish the timing belt in the reverse sequence. Before installing the belt, we are convinced of the combination of installation labels of the crankshaft and distribution shafts. We put on the belt on the gear pulley of the crankshaft, then ...

If necessary, we print the pulley of the camshaft towards the smallest move before the coincidence of the belt tooth with the pulley's depressions. For belt tension, you need to turn the tensioning roller counterclockwise. To do this, insert the outer disk of the roller ... DSC_8

Excessive belt tension reduces its service life, as well as the service life of the coolant pump bearings and the tensioning roller. Insufficient belt tension also leads to its premature failure and can cause a violation of gas distribution phases. We rotate the crankshaft for two turns clockwise. We check the belt tension and the coincidence of the installation labels of the crankshaft and distribution shafts. When the generator drive pulley is removed, the correct position of the crankshaft is conveniently monitored ...

Engine Lada grants 8 valve 1.6 liters today is the most popular among buyers. budget sedan. The engine design is well known not only in the official service, but also in any garage. So repair and maintenance this motor Does not cause difficulties and is relatively inexpensive. Today we will talk more about this engine more.

Gasoline Power Unit Lada Granta VAZ-11186 with a capacity of 87 hp 1.6 liter working volume came to replace the injector engine VAZ-11183 developing 82 horsepower. Increase the power and efficiency of the power unit managed to be new lightweight piston group From Federal Mogul. Of course, the motor is not distinguished by enchanting dynamics and low flow Fuel, but its relatively simple design and maintainability allows us to talk about a good version for our harsh operating conditions.

As for the device of the technical part, the basis of the cast iron block of cylinders, aluminum head, aluminum cylinder cylinder cover, steel crankcase steel pallet. In the drive of GRM Lada Grant 8-CL. Standing belt. The eight-flaped GHM mechanism does not have hydrocomathers, the adjustment of the valves is rare, but the process is quite painstaking. It is necessary to select "Pyataki" of different thickness and lay them between camshaft cams and bottoms of the pushers. The first time this procedure is carried out on the so-called "0" zero, after 3000 km of mileage.

The eternal question does the valve bend on the grant engine VAZ-11186 when cutting a timing belt? The answer is unequivocal, when the belt break valve Gnet! As a pair of motor attached 5-speed mechanical box Transmissions, other options are not provided.

Another feature of the motor can be called the location of the water pump (pump), which rotates all the same timing belt. That is, in the case of leakage of coolant or characteristic noise / whistle / groul in the GDM drive area, the belt check is required. If the pump bearing rates and the belt flies, then besides replacing the body of the water pump and the belt, it will also have to go through the head of the cylinder block, removing the bent valves from there.

The timing belt on the eight-chipped Lade Grande is a link that binds camshaft with crankshaft. It works almost without noise. Some engines use metal chains. They, of course, have their advantages, but they still publish a decent noise.

The timing belt on the Grande can not break off suddenly. The cliff is preceded by a fairly long destructive process. If the opening occurs during the movement, it will definitely be the cause of the collision of the valves with the piston system. Because of this, the valves will definitely be afraid, and this is an expensive repair. In order not to impart such damage, it is necessary to change the belts on time, and so that the replacement is timely, you need to diagnose their condition during exploitation. Experts argue that the replacement of timing belts Lada Grant is needed after 60,000 km. Of course, this is just a recommendation, and you should not forget about the diagnosis in any way.

Other connoisseurs say that the belts begin to collapse after 40,000 km, and it is then to change them.. And yet, quite often, the belts are not torn out due to the fact that they are completely worn out, but because of the breakdowns of rollers or pumps. In case of strong wear or belt break, it must be replaced. To do this, you can contact the car service, and you can do it yourself. Although this operation is quite complicated, but it is still under the power of it and a non-professional. To do this, we need a mounting, a large screwdriver and keys to 10 and 17. Replacing the belt on the 8-valve ode is almost identical to the replacement of this node on a 16-valve.

Of course, the causes of the cliff can be the most different, among other things, it can occur and due to the low level of quality assembly quality at the factory. The poor-quality material also may well take place. One of the main causes of wear is the incorrect operation of the machine. Manufacturers of Lada Grand argue that the timing unit should be seriously examined only after 200,000 kilometers, but it, to put it mildly, does not quite correspond to reality. And if you remember about russian roads, it becomes quite clear that it is definitely not the case.

Replacement process

First of all, you will have to remove rechargeable terminals. Then the generator drive belt is dismantled. To make a dismantling of the node you are interested in, we need to ensure the most complete access to it. Because of this, you will have to remove the front wheel on the right. On this preparation, the replacement can be considered complete, and the replacement itself begins.

Before direct replacement, you need to dismantle the mechanism of timing. It must be done in order to set the first piston to the top position. To do this weaken the nut of the tensioning mechanism. After that, the belt will definitely be ashamed and will lead.

Now we need to unscrew the main bolt of fastening the generator pulley.

Make it possible with the most common key. It may well occur so that the bolt will not leave the Skif. If this happens, do not worry, but simply do the following: Remove the plug in the clutch carcene. At the same time, do not forget to fix the teeth of the flywheel. To do this, you can use the usual mounting. Now the pulley bolt is no longer scrolled, because the crankshaft is in a state of fixation. And then it is easily removing the pulley of the generator.

Remember that the pulley should be removed only after the mount will be extracted.

Attention! After removing the pulley put on something clean, for example, on a rag. Remember that if the aggregate node gets the garbage, it may well be the cause of the encamination.

Now the time to remove the top cover of the timing cover. To remove the bottom of the cover, you will have to unscrew 3 fastening bolts. Then you can make a direct removal of the timing belt. If it is not amenable, let it easily with its installation. After dismantling the belt, it is necessary to check the status of the tensioning roller. Especially it is necessary to look at the level of the backup. Appearance Also can say a lot about the state of this node. To remove the belt it was more convenient, you first need to remove it from the distribution pulley, and then from the crankshaft.

The assembly of the node is made in the reverse order, while it is worth correctly adjusting the belt stretch.

Replacing the timing of Lada Grant 8 valves It takes every 75 thousand mileage kilometers. If you ignore the planned replacement of the belt, the tensioning roller and sometimes the pump (coolant pump), then it can be part of a serious repair engine Lada GRANTA. After all, the scope of the belt of the gas distribution mechanism almost always leads to damage to the valves, the saddle of the valves and even the pistons. Therefore, the timing of timing must be very careful. Once 15 thousand it is necessary to inspect the belt for breaks, cracks, detachments or grinding. Detailed scheme Drive timing Lada Granta further.

To replace the drive belt of the gas distribution mechanism, we should dismantle the generator drive belt or drive belt auxiliary aggregates For a grant with air conditioning. Hexagon "On 5" turn the four screws of the fastening of the front top cover of the timing cover and remove the plastic casing.

In order to avoid damage to the crankshaft position sensor, it is necessary to remove it. When the ignition is turned off, press the wiring harness pad and disconnect the shoe from the sensor connector. Head "On 10" turn the sensor fastening bolt.

We take out the sensor from the tide hole of the oil pump cover and lay it into place where there are no steel sawdust that can subsequently disrupt the sensor operation.

Before dismantling the belt, it is necessary to check the engine gas distribution phases - set the piston of the 1st cylinder to the NMT position (upper dead point) of the compression tact. The head "on 17" turn the crankshaft clockwise for the generator drive pulley attachment bolt until the label is aligned on toothed pulley The camshaft with tide 2 on the rear cap of the timing of the timing.

To make sure the crankshaft position is correct, take out the rubber plug of the viewing window at the top of the clutch crankcase. Risk 2 on the flywheel must be located opposite the slot 1 of the scale that is visible in the clutch crankcase cover window.

Before turning around the exchanger drive pulley, we ask the helper to fix the crankshaft from turning, inserting a screwdriver through the clutch crankcase through the window.

The head "On 17" turns over the generator drive pulley attachment bolt, remove the pulley and the washer.

Hexagon "On 5" turn over the three screws of the fastening of the front bottom cover of the timing of the timing. Remove the lid.

The keyproof key "on 15" weakening the tightening of the tension roller mounting bolt.

In this case, the tensioning roller will turn the belt tension to weaken. Remove the timing belt from the pulleys of the crankshaft and distribution shafts. Take out the belt out motor compartment Grants.

Attention! After removing the timing belt, it is impossible to turn the crankshaft and distribution shafts to avoid pistons in the valves. Dimensions of the gear belt Timing Lada GRANTA with 8 valve engines - 17 mm width, the number of teeth 113.

To remove the tensioning roller, the timing belt turn the bolt of its attachments and remove the tensioning roller along with the bolt.

Rotate the plastic roller clip while holding it for eccentric. The roller must rotate silently, evenly without jamming. Otherwise, the roller must be replaced.

At the same time, you can check the health of the coolant pump, twisting and shocked for the pulley. We set the tension roller into place, finally without tightening the bolt of its attachments. For different modifications of the engine in the cylinder head, two threaded holes under the tension roller mounting bolt are made. The roller fastening bolt is screwed into the upper hole of the cylinder head. In the photo below the hole is indicated by a red arrow.

We establish a grant timing belt in the reverse sequence. Before installing the belt, we are convinced of the combination of installation labels of the crankshaft and distribution shafts. We put on the strap on the gear pulley of the crankshaft, then pulling both branches of the belt, wear the rear branch on the pulley of the coolant pump and start it for the tension roller, and the front - we put on the pulley of the camshaft.

Such a key was used when adjusting the belt tension in all front-wheelwater vases, you can buy it at any auto parts store.

Also to adjust the tension of the timing belt Lada Granta, you can use forceps for removing the locking rings. We stretch the belt by turning the belt tension roller counterclockwise until the matching of the exterior roller disk with a rectangular protrusion of its inner sleeve, and tighten the roller mounting bolt with a torque of 34-41 nm.

If you are not confident in your abilities, you can entrust work on replacing the belt to Lada Grant Car service. For the engine with an 8-valve GHM mechanism, this is cheaper than for a version with a 16 valve motor.

The timing belt on the 8-valve grant is the link between the camshaft and the crankshaft. Grant 8 Timing belt The valve acts as a flexible connection that provides a silent operation process (the iron chain in old engines created a decent noise).

The breakdown of the timing belt on the grant is accompanied by its gradual destruction. The complete destruction of the belt, at the time of the vehicle movement, leads to a collision of the pistons with the valves, as a result of which the latter test various kinds of damage, most often - bent. The only way to avoid damage to the valves is the premature replacement of the timing belt, which is registered in the car service book.

Engines Lada grants 11183, unlike engines of other vase models, need to be replaced by timing every 60 thousand km. Replacing a belt with such a mileage is solely recommendation of the car manufacturer.

In order to achieve the maximum safety and integrity of the mechanisms of the car engine, it is recommended to replace every 40 - 50 thousand km. It is at this stage that rollers and a pump begin to be rolled.

In most cases, the timing belt breaks not as a result of the complete wear of its structure, namely, failure (wedge) rollers or pumps.

In the event that after all, the timing belt Lada Grant 8 valves broke up, the following tools must be used to replace:

Key to "10"; key on "17"; mounting blade; Special key of adjusting the timing belt tension.

Performing work on replacing the timing belt on the 8-valve engine corresponds to the following instruction. As for the 16-valve engine, the instruction is almost identical to the 8-valve.

Replacing the timing belt on the 8-valve engine begins directly with the removal of the terminals from the battery, after which the generator drive belt is already removed. To replace the belt, you must have full access to the necessary aggregate nodes. To implement such an access, it is necessary to remove the front right wheel.

The replacement of the belt is preceded by the disassembly of the GRM mechanism itself, namely the removal of its front top cover. What is the event for? You need to set the first one in position to the ITT position (top dead dot).

Tension Roller Nut Adjustment

It is the corresponding adjustment of the tensioner roller, and more precisely, the use of Lada grant timing belt in fixed tension, determines the resource of the timing belt Lada Grant.

To dismantle the timing used or also a torn timber belt, you must send the tension roller nut, as a result of which the belt will be given in a weakened position. After that, you can proceed to the next step.

IMPORTANT: Do not try to just cut the belt to not unscrew the tension bolts. In this case, you will not be able to wear new belt on shafts.

Generator drive pulley: unscrew the main bolt pulley generator

Cut the generator pulley bolt can be ordinary keys mentioned above in the list required tools. If the bolt does not exit the generator pulley, then the following steps must be performed:

Dismantling plugs in clutch crankcase

Flywheel's teeth are fixed by the mounting blade, the presence of which justified the list of necessary tools.

After performing such actions, the generator pulley bolt will stop scrolling, since the crankshaft will be fixed with the mounting blade.

Dismantling pulley generator

Dismantling of the generator pulley must be performed immediately after the installation of the mounting blade. After the dismantle is implemented, the pulley must be put on a clean surface. The presence of garbage in the aggregate node may result in the evinc.

Dismantling of the bottom cover of the drive drive

The process of dismantling the bottom cover of the GDM drive is carried out by extracting three fastening bolts. This design takes place in the models of engines of grants 21116, as well as 11186.

Dismantling belt timing

The last stage - dismantling the timing belt, followed by the determination of the state of the tensioning roller. The process of dismantling the belt occurs in the following order:

Removing the timing belt from the distribution pulley

Removing the belt from the crankshaft.

It is at the second stage that the timing belt grant is dismantled along with the tension roller. We carry out a visual inspection of the roller, in particular, determine the external state and the level of the back of the mechanism.

At the time of the reverse installation of the bottom cover, it is necessary to adjust the tension of the belt itself.

The reasons for the premature belt cliff on the Lada Grant remain a mystery, which is based on not only the low quality of the material used in the belt, as well as the low quality of the assembly of aggregate nodes, through which the timing belt passes.

Among other reasons for premature belt, the timing belt can be noted the desire for the manufacturer of the car to keep up for Euro-3/4. It is a desire to adjust the car to these standards led to the aforementioned negative moments in daily exploitation car.

Despite the approval of the manufacturer on the quality of the grant, the timing belt and the threshold of his personal run of 200,000 thousand km, he rushes at 70 - 80 thousand km. A good and decent solution to the replacement can be a belt with rollers Gates.

It was Lada Grant from the priory the timing belt comes to the Lade Grant and will not be the cause of premature failure. The price of the timing belt on the grant allows it to change it every 50,000 thousand km, which, in turn, will reduce the likelihood of other costs of expenses regarding the repair of the engine valves.

In this article we will touch problems that can cause a poor-quality or wear belt Lada Grant 8 valves and 16 valves. Despite his simplicity, this item plays a huge role of the engine of the car.

During the functioning of the power unit, it does not matter the 16 CL or 8 CL, the belt is gradually wearing and if it is not possible to replace it in a timely manner, it can completely collapse and breaks it. It is impossible to allow this, because it can lead to such a dangerous phenomenon as valve bending and destruction piston system. In the instructions going along with the Lada Grant car on the 16 CL engine and the eight-ganglap, the recommended replacement period is 60 thousand km. Run. But according to many professionals, this figure is slightly overestimated and it is not necessary to reach it, but you need to replace after 50 thousand kilometers.

Another reason why the belt should be changed before, is that such nodes, like pump and guide rollers, are designed for mileage fifty thousand. After that, their use is risky. The use of these nodes over the term can lead to a blast drive with all negative consequences for the system. But in any case, after how many kilometers run the belt and what better to choose is your personal matter.

What do you need a timing belt

The strap of the gas distribution mechanism on the Lada Grant car is necessary to synchronize the work of the camshaft and crankshaft. In the instructions for the car 16 and 8 cl. The replacement period is regulated. However, nevertheless, most of the motorists know little about it and may not even know its location, not burning about how to change. It is just, you just need to raise the hood cover of the car. At the most prominent place is a toothed belt covering many pulleys. Opening the instruction going together with vehicle You can also easily find a section in which this node is described. The timing belt interacts not only with the crankshaft and with distribution, but also with several systems. Such a load significantly reduces the belt resource, which makes it possible to break it.

Change the belt for yourself

Replacing the timing belt after the prescribed period on the engines 16 and 8 CL of the Lada of the grant is a simple process and even a novice car enthusiast can perform it with their own hands. The main thing is to carefully adhere to all points of instructions and not miss anything.

Required tools

Stages of work

The following important stage is the correct tension of the LADA GRANT Lady GRUT drive with units 16 CL and 8 CL.

Attention! The roller of the stretch should not move or deviate as far as it was in one direction or another, it will be proof that it is in good condition and works correctly. So, his cliff is excluded.
