Lada Vesta timing belt resource. Vesta timing belt: when to change so as not to bent the valve. Pistons that do not bend the valve

The timing belt (timing belt) drives the camshafts and valves in accordance with the positions of the pistons. If you do not monitor this unit, there is a high probability of complete failure of the engine, followed by expensive repairs. What can happen?

A worn belt can break and a worn idler pulley can cause the belt to slip through the teeth. All this knocks down the position of the valves relative to the pistons, which can lead to their "meeting", which usually results in bent valves and camshafts broken into several parts.

If you do not want such consequences, then the only correct solution would be the timely replacement of the timing belt and tension roller. To perform this procedure in a Lada Vesta car, use the instructions below.

Removing the timing belt

To dismantle the timing belt, follow these steps:

Remove the terminal from the storage battery
Lift the car on a lift
Remove the accessory drive belt
Dismantle the crankshaft damper, after stopping the rotation with a screwdriver or a special tool, then tighten the crankshaft bolt

Remove the 2 bolts securing the right support to the internal combustion engine (Torx E12), having previously suspended the engine on a traverse or other device

Unscrew the remaining 2 bolts securing the support to the body (16 mm head) and remove it

Remove the timing belt guard by unscrewing 5 bolts (5 mm hex)

Rotating the crankshaft, align the camshaft marks on the same level with the marks on the rear cover

Loosen the idler roller bolt with a 17mm wrench

Dismantle the timing belt

For convenience, use a special tool: a camshaft lock and a crankshaft lock.

Installing the timing belt

The timing belt must be installed at an engine temperature of +15 to +35 C⁰. Otherwise, there is a high probability of incorrect timing of the timing mechanism, which can lead to unstable engine operation, a decrease in power and an increase in consumption. So, in order to properly install the belt and adjust the timing mechanism, follow these steps:

Align the mark on the crankshaft pulley with the mark on the oil pump

Align the marks on the camshaft pulleys with the marks on the cover
Tighten the tension roller bolt to 5 Nm
Carefully, without knocking out the valve timing, put the belt from the upper pulleys to the lower

Adjust the idler roller using the special wrench

Tighten the tension roller bolt (15 mm head) to 33 Nm
Make sure all marks are in place and turn the crankshaft pulley 2 turns
Assemble all the assemblies in the reverse order of removal.

When to change the timing belt

The timing of replacing the timing belt on the Lada Vesta, as in other cars, depends on many factors. The manufacturer recommends performing this procedure every 90,000 km, however, given the possible consequences of a break, it is recommended to replace it much more often. Especially if your car's engine has significant mileage. Any oil spills, splashes of water and dirt can significantly shorten the timing belt life. So how much mileage does it take to replace? - we recommend changing every 50,000 km.

We answered questions about how to replace and how long to change the timing belt on Vesta. If you still have questions about such a procedure as replacing the timing belt with a Lada Vesta, videos and photos on the Internet will help you answer them. And remember a very important point - diagnose the condition of the timing belt as often as possible, because a broken timing belt can lead to considerable financial and time costs.

In the fall of 2015, the LAD family of cars was supplemented by the top model - the Vesta car, produced in the sedan body. When asking the question "does the valve bend on the Lada Vesta", you need to clearly imagine what kind of engine we are talking about: about a 1.6-liter Russian or Nissan, or maybe about the latest VAZ development with the name "21179".

Here options are considered that are related to cars that are being produced now or those that will begin to be produced in the near future. Also, an 8-valve engine was developed for Vesta - it definitely does not bend the valves and will definitely not be installed on top sedans in 2016.

ICE VAZ-21129, 106 "forces" (valve bends)

Under the hood of a 106-strong Lada Vesta

A bit of history. Motor 21129 is a modified version of another engine, namely, 21127. The last of them, when the timing belt broke, successfully bent its valves, although grooves were made on the pistons (Fig. 1). The point is that the depth of the grooves was not sufficient: when certain conditions were met, the valve "met" the piston with all the ensuing consequences.

With the transition to a new generation of internal combustion engines, that is, to 21129, the design of the pistons was finalized. But the external shape has not changed much, and although the notches remain, their depth is still insufficient.

Here the question was considered whether the Lada Vesta valve with the "21129" engine is bending. And the answer was unequivocal: yes, oppression.

In theory, the problem with valve bending is typical for all VAZ engines equipped with 4 valves per cylinder. Each new 16-valve "inherits" it. An exception is one rarity - the VAZ-2112 internal combustion engine, the volume of which is 1.6 liters. There the notches are made to the fullest (Fig. 2).

122-strong motor "21179" (valve bends)

By its design, the VAZ-21179 internal combustion engine does not differ much from its predecessors. The working volume was increased to 1774 ml, which was achieved by changing the length of the piston stroke: from 75.6 mm to 84.0 mm.

Elements of the connecting rod-piston group

The piston itself is now fitted to the cylinder better than in the 21127 and 21129 engines. The distance from the piston pin to the piston crown has increased by 1.3 mm to 26.7 mm. But deeper grooves in the bottom did not appear. The timing mechanism still drives the belt, and when it breaks, no one canceled the ability to bend the valves.

Now we know if the valves are pressed on the Lada Vesta with a 1.8-liter engine. The answer will be the same as for all 16-valve VAZ internal combustion engines (with the exception of 2112). The problem with the transition to a new generation remains the same. And they do not intend to return to the "heavy" pistons at the VAZ.

The timing drive on 21179 engines is equipped with not one, but two tension rollers. What has been done so that the structure is less susceptible to tension in the timing belt.

It says here: the number of idler rollers is two

One of the automatic tensioning machines can jam, but then the second automatic roller will take over its function.

Pistons that do not bend the valve

Piston kits for some "old" 16-valve valves are available from third parties. These parts are supplied with deep grooves. The point is that the piston does not reach the plates and cannot bend the valves.

Tuning piston for internal combustion engine 21126-21127

ShPG elements of different engines (21127, 21129, 21179) are compatible. But it is not necessary to install pistons from "old engines" into Vesta's engine:

In the internal combustion engine 21129 after such "tuning" the friction losses will increase;
If the pistons from the 26th or 27th engine are installed in the ICE 21179, the working volume will immediately change.

"29th", as well as "79th" engine Lada Vesta bends valves only with "VAZ" pistons. But after installing a "tuning" part, do not expect an increase in power. And also, using non-standard elements, you can greatly reduce the resource (lose the warranty, get unforeseen consequences).

Nissan HR16DE engine (not oppression, there is a chain)

Disassembled HR16DE engine

No "deep grooves" are provided here. Now let's pay attention to how the timing mechanism works.

Nothing but gears and chains

There is no toothed belt here - it is replaced by a chain. It is difficult to imagine the following two situations:

The chain could jump over the teeth of one or more gears;
One of the elements was damaged so badly that the damage caused it to rupture.

As long as the chain remains intact, valves and pistons cannot meet each other, no matter what happens to the engine. The only bad thing is that the chain can jam.

Is the Lada Vesta valve bending with a Nissan ICE? The answer "no" would be wrong - breaking the circuit is not ruled out. But in reality, it will be almost impossible to face such a situation. Let's see why.

Four well-known facts

The resource indicator for the timing chain always exceeds the engine life. This is the first fact, but the condition must be fulfilled: the oil change must be timely. In general, the chain breaks down gradually, and this is accompanied by symptoms:

Audible overtones (chirping) at idle;
At the moment of passing the "problem area", a phase shift may be observed.

The last defect is detected using computer diagnostics.

It takes a certain amount of time from the appearance of any symptom to the complete breaking of the circuit. And in general, a "defective circuit" can work for a long time. This was another, fourth fact.

The consequences of a broken timing belt, an example in the video

Engine Lada Vesta volume of 1.6 liters appeared under the hood of the sedan for a reason. This is a fairly reliable power unit, which has managed to take root on other Avtovaz models. The simple design of the inline 4-cylinder 16-valve engine VAZ-21129 has its own characteristics. Durable cast iron cylinder block, aluminum cylinder head, timing belt drive. There are no hydraulic compensators in the 16-valve cylinder head; valve clearances are adjusted by selecting special washers of different thicknesses. Motor power Lada Vesta 1.6 is 106 hp. with a torque of 148 Nm.

Electronically controlled multipoint fuel injection requires the use of AI-92 gasoline... The Lada Vesta engine complies with Euro-5 environmental standards. The main design feature is a dynamic (passive) intake system. In the intake manifold, air can move at different speeds thanks to special dampers. This allows you to optimize fuel consumption and increase dynamic performance at different engine operating modes.

The Lada Vesta engine also has problems. First of all, it is necessary to note the danger of breaking the timing belt. Indeed, in the event of a break in the timing belt on Lada Vesta 1.6, the valve bends that meet the piston crowns. Therefore, it is necessary to change the Vesta timing belt clearly according to the manufacturer's regulations.

Engine Lada Vesta 1.6 fuel consumption, dynamics

Working volume - 1596 cm3
Number of cylinders - 4
Number of valves - 16
Timing drive - belt
Cylinder diameter - 82 mm
Piston stroke - 75.6 mm
Power hp / kW - 106/78 at 5800 rpm
Torque - 148 Nm at 4200 rpm
Compression ratio - 10.45
Maximum speed - 175 kilometers per hour (with the "robot" AMT 178 km / h)
Acceleration to the first hundred - 11.2 seconds (with the "robot" AMT 14.1 seconds)
Fuel type - gasoline AI-92
Fuel consumption in the city - 9.3 liters (with the "robot" AMT 9.0 liters)
Fuel consumption in the combined cycle - 6.9 liters (with the "robot" AMT 6.6 liters)
Fuel consumption on the highway - 5.5 liters (with the "robot" AMT 5.3 liters)

Engine Lada Vesta is combined with both a manual 5-speed gearbox and a robotic automatic machine AMT. Mechanics is a box Renault JH3, which is put on Renault Logan, and produced in Togliatti. In terms of dynamics, a manual transmission is preferable.

Robotic box automatic machine AMT VAZ-21827 created on the basis of a conventional 5-speed mechanics. The dynamics with the "robot" on the Lada Vesta is very inexpressive. This state of affairs is associated with the settings of the machine. First of all, the developers tried to create an economical unit, and the dynamics were simply sacrificed to this desire. On the other hand, it is better to navigate through traffic jams in large cities of the country automatically. In a traffic jam, a speaker is not required at all. Everything about . Fans of the Russian car industry have finally waited for the powerful Vesta.

Nissan HR16DE engine (not oppression, there is a chain)

In most configurations with a manual transmission, the Vesta sedan is equipped with a Nissan engine. This engine is planned to be installed on bodies: station wagon, cross and coupe! Its name is HR16DE, and the working volume is 1.6 liters. Let's take a look at what the piston crown looks like.

No "deep grooves" are provided here. Now let's pay attention to how the timing mechanism works.

There is no toothed belt here - it is replaced by a chain. It is difficult to imagine the following two situations:

The consequences of a broken timing belt, an example in the video

It is noticeable that VAZ specialists, working on the new Lada Vesta sedan, set themselves the goal of ensuring maximum reliability and problem-free model. That is why the powertrain lineup includes motors familiar from other Alliance vehicles. Of course, they have weak points, but all "childhood diseases" have long been defeated and by modern standards, these motors are considered very reliable.

What engines are installed on the Lada Vesta?

Three power units were saved for the novelty, two of which are domestic, and one is imported:

VAZ 21116 - 1.6 liters, 8 valves, 87 liters. With.;
VAZ 21127 - 1.6 liters, 16 valves, 106 liters. With.;
Renault-Nissan HR16DE-H4M - 1.6 liters, 16 valves, 114 hp With.

Problems with the VAZ 21116 engine

This is a modified power unit of the VAZ 21114 type. The modifications resulted in the installation of a 39% lightweight ShPG from Federal Mogul. The engine is good because when the timing belt breaks, the valve does not bend. Nevertheless, if signs of a malfunction are detected, it is better not to delay and immediately go to the service station.

Engine design features

The operation of this power unit has a number of distinctive features:

- the need for periodic valve adjustment;

- frequent replacement of the oil filter;

- rapid wear of the components of the cooling system;

- oil leaks through a poor-quality valve cover seal;

- frequent breaking of the brackets on the intake exhaust pipe - instead of brass nuts, steel nuts are used.

Typical malfunctions

Friction and uneven operation - to find the cause, it is required to measure the compression in the cylinders. If in one of them it is noticeably different, this means that the valve is burnt out. With a slight difference in performance, the source of the problem is in the gasket, or you just need to adjust the valve. If everything is fine with compression, the cause should be looked for in the ignition module.

Floating RPM - This is usually a problem with newer machines. To fix it, you should go to the service center, where it will be eliminated under warranty. Otherwise, it is required to inspect the vacuum cleaner, the throttle position sensor and the idle speed regulator.

The engine does not heat up to the required temperature level - it's the thermostat. In addition, even new components often fail. Consequently, the breakdown may recur soon after replacement.

Engine noises and knocking - usually the whole thing in the valves that need to be adjusted. If, however, a muffled metallic rumble is heard, increasing when the accelerator pedal is pressed, then the connecting rod bearings or the crankshaft bearings rattled. This problem is solved only in the service. The knocking of the pistons in the cylinders is also possible. This is also a reason to visit the dealer at the service station.

Problems with the VAZ 21127 engine

The VAZ 21127 engine is a slightly modified and modified power unit of the VAZ 21126. The differences lie in the installed intake system, equipped with a resonance chamber with the ability to adjust its volume due to controlled dampers.

Instead of DMRV, the designers installed DBP + DTV, which eliminated the problem with floating turns. Like its predecessor, this engine also bends the valve when the timing belt breaks.

Peculiarities

Owners of Lada Vesta need to take into account possible problems, as well as know the options for solving them:

Unstable operation and inability to start - can be triggered by irregularities in the operation of the timing, problems with fuel pressure, air leakage, breakdown of the throttle valve, as well as a malfunction of some sensors.
Loss of power - the cause is a burned-out gasket, as a result of which the compression in the cylinders decreases, as well as the wear of the components (burnout of the pistons, wear of the rings and cylinders). However, the owners of the new Vesta are not threatened with such problems (at least at first).
Valve bending - this problem can be solved by replacing the standard pistons with those of the plug-free type.

Typical malfunctions

They are similar to those that characterize the VAZ 21126 engine.

The Vesta VAZ 21127 engine can start to troit. In this case, flushing the nozzles will not be superfluous. If this procedure does not help, you should pay attention to the ignition coils, spark plugs and measure the compression. However, it is best to immediately go to the service station.

There may also be a problem of warming up to operating temperature. This usually occurs when the thermostat is faulty.

Noises and knocks in the engine can occur due to hydraulic lifters, as well as problems with the main and connecting rod bearings or pistons. If vibration occurs in the Vesta motor, it is worth inspecting the nozzles and high-voltage wires.

Renault-Nissan HR16DE-H4M

The production of this power unit was launched in 2006. In general, the engine, which so far remains the most powerful in the Vesta lineup (the output of a 1.8-liter unit is questionable), is considered very reliable and is capable of driving about 250,000 km to the "capital".

Focused on the AI-95, but easily "digests" the 92nd. In addition, in his timing system, a chain is used that is reliable, so the owners of Vesta should not worry about stretching it too early.

Typical malfunctions

There are few of them:

The Vesta motor can stall - the reason is a breakdown of the ignition unit relay. And Nissan has already recalled the cars because of this. In this case, you will have to buy a new relay for Vesta.

Whistle - it is typical for many Nissan engines. In this case, Vesta may have a generator belt whistling, which will need to be tightened or replaced.

Vibration - to eliminate this phenomenon, it is usually enough to change the right motor mount.

Burned-out exhaust pipe ring - the car starts to work louder. The gasket needs to be replaced.

As you can see, Lada Vesta will be equipped with proven power units. All their weak points have long been known from experience on other models. However, the top-end, 114-strong HR16DE-H4M promises to be the most problem-free.

Replacing the timing belt of the car Lada Vesta

We prepare the car for work. We install the car on a lift or on a viewing pit. Disconnect the negative terminal of the battery.

Remove the drive belt.

We stop the flywheel from turning.

With a 17 head, unscrew bolt 1, Figure 1, damper mounts, remove washer 2 and crankshaft damper 3.

We wrap the damper mounting bolt in place.

Remove the flywheel locking device (if applicable).

We install the traverse 1, Figure 2, on the car to hang the engine, put the hook 2 of the traverse into the eyelet 3 of the right eyelet, and hang the power unit on the right side.

Using the TorxE12 head, we unscrew and remove two bolts 1, Figure 3, fastening the power unit to the right support 2 of the engine mount.

We mark with a marker the position of the right support.

With the same head, we unscrew the two bolts 3 securing the right support of the suspension of the power unit to the body and remove the right support.

Using a 5 hexagon, unscrew the five bolts with washers, and remove the upper protective cover 1, Figure 4.

We unscrew the three bolts with the same wrench and remove the lower protective timing cover.

With a 17 key, turn the crankshaft by the damper mounting bolt until the mark on the crankshaft toothed pulley matches the mark on the oil pump housing. In this case, the marks of the camshaft pulleys must coincide with the marks on the rear protective cover.

We loosen the bolt 1, Figure 5, fastenings of the automatic tensioner 2, unscrewing it by 2 - 3 turns, and remove the distance washer and the timing belt 3 from the crankshaft pulley (use a 17 spanner wrench and a flat screwdriver).

Continuation of the article on page 2 ..

The main task of the timing belt (timing belt) is to transfer the rotation of the crankshaft to the camshaft, which presses the cams on the valves. This article will tell you about when and how you need to change this part on eight- and sixteen-valve engines installed on a Lada-Vesta car.

What is the time to replace the timing belt on the Lada-Vesta

According to the maintenance regulations, it is necessary to change the timing belt for a "Lada-Vesta" with engines 21129, 21179 (16 valves) with a mileage of 180 thousand kilometers. Check the condition - every 90 thousand kilometers. For modifications with 8-valve 11189, these intervals are less - 70 and 15 thousand kilometers, respectively.

Part numbers

Since on the installed motors in the piston bottom there are no grooves for the valves, which make it possible to avoid bending them when the belt breaks, there is no need to save on this consumable. It is preferable to install an original belt or a replacement from Contitech and Gates.

Original

In the spare parts catalog of AvtoVAZ, the required spare parts are indicated by the following numbers:

2108-01006040-82 for engine 11189;
8201069699 for engines 21129 and 21179.

The minimum price for exist.ru is 360 and 2500 rubles, respectively.

Replacing the timing belt on Vesta with a 21179 engine (1.8 liters, 16 valves)

The process of replacing the timing belt on this motor does not differ from replacing on the 21129 engine.

In custody

Summing up, we can say that replacing the timing belt with a Lada-Vesta with 16-valve power units is a complicated procedure in comparison with replacing it with an 8-valve motor. If you don't want to bother with this work, then it is better to entrust it to auto mechanics at the service station. The replacement cost will be from 4000-5000 rubles.
