When to change the timing for a grant of grade 8 Timing Belt Test for Lada Granta: The Most Important Drive

The second method, using a suspended wheel, was described above. When the marks coincide, you need to remove the rubber plug located on the gearbox and open the inspection window. A flywheel is visible in it, the risk on it should also coincide with the slot on the body. The next step is to remove the belt from the generator drive pulley. To do this, loosen the lower mounting bolt of this unit, and unscrew the upper one and pull it out.

Then the generator housing can be moved forward and the belt removed from the pulleys. Immediately, using the moment, you can examine the removed belt for defects and damage, and, if necessary, change it. This is followed by the operation to loosen the bolt holding the pulley crankshaft... It often happens that it is impossible to do this just like that with a spanner wrench, especially after the factory tightening. There are several ways.

Insert a flat powerful screwdriver or pry bar into the flywheel viewing window, blocking it. Holding the screwdriver with your right hand, loosen the pulley bolt with a 17 mm wrench with your left.
If there is an assistant, the procedure is greatly simplified. One will turn on the 4th gear, press and hold the brake pedal, at this time the second will unscrew the pulley. It is much more convenient to do this, both hands are free to work.
Some motorists put a spanner wrench on the pulley bolt and push it against some body or suspension element, after which they turn the crankshaft with a starter in neutral. The method is quite dangerous, it is permissible to use it in the most extreme case, when it is impossible to loosen the bolt by other methods.

After the bolt is unscrewed, the pulley is removed and the working part is wiped with a rag. Then you need to loosen the tension roller bolt, the belt tension will loosen and you can remove it. Since the roller must also be changed, it must be unscrewed. The last piece to be removed is the lower mechanism cover, which is attached to the engine with three bolts.

This completes the disassembly of the unit. Before installing a new roller and timing belt, you need to make sure that the pump drive shaft rotates freely and does not wedge. Otherwise, you will have to make a decision to replace the coolant pump.

Reassembling the mechanism

The assembly process is carried out in the reverse order, only at the very beginning you need to make sure that the marks set earlier are in their places. Then a new tension roller is placed and put on the gears new belt Timing, starting from the bottom, from the crankshaft. Supporting the belt with a slight tension by hand, put it on the camshaft gear so that all the teeth match, and then tighten it with a tension roller.

In its case there are 2 holes into which you can insert a special fork or round-nose pliers, with their help and stretch. Then tighten the roller bolt with medium force. In order to make sure of correct installation and belt tension, it is necessary to make a couple of full revolutions of the crankshaft, preferably not with a starter, but with a key. Then align the marks and check again the position of the marks in the flywheel inspection window.

There is one nuance: the risk on the camshaft gear can deviate by a couple of mm in one direction or another from the mark on the body, this is quite acceptable. If the belt is installed incorrectly, the discrepancy will be 1 cm, this is immediately noticeable. It is necessary to again loosen its tension and rearrange the belt one tooth to the right or left, and then repeat the operation. When the new belt is successfully installed and tensioned, the assembly can be reassembled.

When installing the generator drive belt, it should be remembered that there is no tensioning mechanism on the VAZ 2190. Therefore, the body of the unit is moved as close as possible to the cylinder block, the belt is put on its pulley completely, and partially on the crankshaft, after which it will need to be turned half a turn so that the consumable fits into place. Further assembly is not a problem, after which you can start the motor. The operation for such a replacement for a 16-valve Lada Grant engine is distinguished by such details.

There are two camshafts, the marks will need to be combined, and then checked on two gears.
You need to change 2 rollers: tension and bypass.
The new belt will need to be carefully put on the two upper gears, passing it past the bypass roller, the process is somewhat more painstaking.

During the replacement work, it is recommended to pay attention to the cleanliness inside the space of the timing mechanism. As a rule, dust, dirt, waste products of the old belt in the form of black powder and so on accumulate there. It will be correct to thoroughly wipe the motor housing, gears and the protective cover from the inside.

The whole procedure is quite simple. Knowing how much to change the consumables of the timing mechanism and having a minimum set of devices, everyone can do it independently.

We hang out the right front wheel and turn on the fifth gear in the gearbox. Turning 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 must not have folds, cracks, undercuts of teeth and peeling of fabric from rubber. The underside of the belt should be free of wear, exposing the cords, and burn marks. There should be no delamination or loosening on the end surfaces of the belt. If defects are found on the belt or a significant mismatch of the belt tension control elements (see photo above), the belt must be replaced. You should also change the belt to a new one if traces are found on it. engine oil (before installing a new belt, the cause of oil on the belt must be eliminated) or when replacing the coolant pump.

Attention! Failure of the timing belt (breakage and shearing of teeth) can lead to the valves sticking into the pistons due to the mismatch of the angles of rotation of the crankshaft and camshafts and, as a result, to expensive engine repairs.

We replace the timing belt in accordance with the maintenance schedule every 75 thousand kilometers or in case of defects on the belt.

Next, we should dismantle the alternator drive belt or the accessory drive belt.

To avoid damage to the crankshaft position sensor, remove it.

Before dismantling the belt, it is necessary to check the valve timing of the engine - set the piston of the 1st cylinder to the TDC (top dead center) position of the compression stroke.

Before loosening the bolt securing the alternator drive pulley ...

Using the "17" head, unscrew the bolt securing the alternator drive pulley, ..

This will rotate the tension roller and release the belt tension. Remove the timing belt from the crankshaft and camshaft pulleys.

Attention! After removing the timing belt, do not turn the crankshaft and camshafts to avoid the pistons sticking into the valves.

To remove the belt tension roller, unscrew the bolt of its fastening ...

The roller should rotate quietly, evenly and without jamming. Otherwise, the roller must be replaced. At the same time, you can check the serviceability of the coolant pump by twisting and shaking it by the pulley. We install the tension roller in place, completely without tightening the bolt of its fastening. For different engine modifications, two threaded holes are made in the cylinder head for the tension roller bolt.

Install the timing belt in reverse order. Before installing the belt, make sure that the timing marks of the crankshaft and camshaft are aligned. We put the belt on the crankshaft toothed pulley, then ...

If necessary, turn the camshaft pulley in the direction of the smallest stroke until the teeth of the belt coincide with the grooves of the pulley. To tension the belt, turn the tension roller counterclockwise. To do this, insert into the grooves of the outer disk of the roller ... DSC_8

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

Breaking the timing belt on Grant is accompanied by its gradual destruction. The complete destruction of the belt, at the time of the movement of the car, leads to a collision of the pistons with the valves, as a result of which the latter suffer various kinds of damage, most often they bend. The only way to avoid damage to the valves is to prematurely replace the timing belt, the moment of which is registered in the car's service book.

Lada Grants 11183 engines, unlike engines of other VAZ models, need to be replaced with a timing belt every 60 thousand km. Replacing the belt with this mileage is solely the recommendation of the car manufacturer.

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

In most cases, a timing belt breakage does not occur as a result of complete wear of its structure, namely, failure (wedge) of rollers or a pump.

In the event that, nevertheless, the Lada Granta timing belt of 8 valves broke, the following tools must be used to replace:

Key to "10";
key to "17";
mounting blade;
special key for adjusting the timing belt tension.

Carrying out work on replacing the timing belt on an 8-valve engine follows the instructions below. As for the 16-valve engine, the instructions are almost identical to the 8-valve one.

Preparing to replace the timing

Replacing the timing belt on an 8-valve engine begins directly by removing the terminals from the battery, after which we already remove the generator drive belt. To replace the belt, you must have full access to the necessary aggregate units. To implement this access, the front right wheel must be removed.

Replacing the belt is preceded by the disassembly of the timing mechanism itself, namely the removal of its front top cover. Why is such an event held? The first piston must be set to TDC (Top Dead Center).

Adjusting the tension roller nut

It is the appropriate adjustment of the tension roller, or rather the use of the Lada Granta timing belt in a fixed tension, determines the resource of the timing belt Lada Granta.

To dismantle a used or torn timing belt, loosen the tension roller nut, as a result of which the belt will be brought into a weakened position. After that, you can proceed to the next stage.

Important: do not just try to cut the belt so as not to unscrew the tension bolts. In this case, you cannot fit the new belt onto the shafts.

Alternator drive pulley: unscrew the main alternator pulley bolt

You can unscrew the alternator pulley bolt with ordinary keys, which were mentioned above in the list necessary tools... If the bolt does not come out of the generator pulley, then the following steps must be performed:

Removing the plug in the clutch housing

The flywheel teeth are fixed with a mounting blade, the presence of which was justified by a list of necessary tools.

After completing these steps, the generator pulley bolt will stop rotating, since the crankshaft will be fixed with a mounting blade.

Removing the alternator pulley

Dismantling the alternator pulley must be done immediately after removing the mounting blade. After dismantling is carried out, the pulley must be placed on a clean surface. Debris in the power pack can cause it to jam.

Dismantling the lower timing cover

The process of dismantling the lower timing cover is carried out by removing three mounting bolts. This design takes place in the Grants 21116 engine models as well.

Dismantling the timing belt

The last stage is the dismantling of the timing belt with the subsequent determination of the condition of the tension roller. The belt removal process takes place in the following order:

Removing the timing belt from the timing pulley

Removing the belt from the crankshaft.

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

At the time of reassembling the lower timing cover, it is necessary to adjust the tension of the belt itself.

The reasons for the premature breakage of the belt on the Lada Grant remain a mystery, which is based not only on the low quality of the material used in the belt, but also on the poor build quality of the aggregate units through which the timing belt passes.

Among other reasons for the premature break of the timing belt, one can note the desire of the car manufacturer to keep up with Euro 3/4. It was the desire to fit the car to these standards that led to the aforementioned negative moments in the daily operation of the car.

Despite the manufacturer's assertions about the quality of Grant, the timing belt and the threshold of his personal run of 200,000 thousand km, it is already torn by 70 - 80 thousand km. A good and worthy replacement solution would be a Gates roller belt.

It is the Lada Granta from the priors that the timing belt will fit the Lada Granta and will not cause premature failure. The price of the timing belt on the Grant allows you to change it every 50,000 thousand km, which, in turn, will reduce the likelihood of other items of expenses related to the repair of engine valves.

Before you start replacing the belt, you should actually purchase it. To find any spare part you need near you, go to http://autokontact.com/, and the service will immediately give you the nearest stores. Then, we proceed to the replacement.

To replace the timing belt with an automatic tensioner, take a 5 mm wrench. Unscrew the 4 bolts on the front top cover and remove it.

We install the car on a secure stand by removing the right front wheel.

Remove the right side of the engine mudguard and then the alternator drive belt.

We begin to rotate the crankshaft until the marks on the camshaft pulley and the rear belt cover are aligned with a 17 mm socket wrench. The position of coincidence of these marks corresponds to the position of the piston of the first cylinder in the extreme top position, which is called top dead center (TDC). Attention! Do not turn the crankshaft using the pulley bolt! The crankshaft can be held by the flywheel ring gear with a slotted screwdriver, while removing the rubber plug located on top of the clutch housing. Also, the crankshaft pulley bolt can be unscrewed if the assistant shifts into high gear and presses the brake pedal. However, the crankshaft may turn slightly. Therefore, you need to re-verify that all labels match.

Then you need to unscrew the bolt securing the pulley and remove it.

We take a 5 allen wrench and unscrew the 3 bolts that secure the lower belt cover, and remove it.

Remove the restrictor washer from the crankshaft.

Now we take the key 15 and slightly loosen the belt tension by turning the automatic tensioner mounting bolt half a turn counterclockwise.

We remove the timing belt and check the condition of the tension roller by rotating it. If it makes a lot of noise or play is visible, it must also be replaced.

Now we put on a new belt. We make sure that the mark of the crankshaft toothed pulley docked with the tide made on the oil pump housing.

We put the belt on the camshaft pulley so that the front branch is taut. Without allowing the belt to loosen, we put it on the pump pulley and on the tensioner pulley.

We hang the right front wheel and include the fifth gear in the gearbox. Turning the wheel clockwise, we turn the engine crankshaft and inspect the timing belt. With normal belt tension ...
