Shaving the timing belt fret grant 8 valves. Yak fret grant gnіt valve kak dіznatisya. Closure of valves on Priori - theory and practice of the problem. How to avoid vigin valve inserts

Sergio Marchionne, saying: “I’m going to shoot you first,” if he was asked about the possibility of entering the segment of the foreigners. Hours are changing, markets are developing, and the Italian manufacturer of supercars has confirmed that it is actively developing its first model of a Russian brand for driving on a high speed. Vіn bude will be strongly vіdіznyatisі vіd be-yakoy pozashlyahovik on the market.

Idea Ferrariє spiral, navit deep in the middle of the company's headquarters, or perhaps the best guarantees way to increase profits and get new buyers. Porsche, Bentley, Lamborghini and Rolls-Royce are already in the arena, and Aston Martin will arrive before the end of 2019. The Ferrari model will not be released before 2022, so the company will stay in the trend. This approach has pluses and minuses. Ferarri needs to report chimalih zusil, so that this model has been seen, but it is in an ideal position, so that you can learn valuable lessons from your competitors.

At the poshlyahovik Ferrari while you can’t name it, but in the middle of the company they call it Purosangue, which in Italian means “purebred”. Tse talk too much about what. Vіn bude deyakі pozashlyahovі funktsії, but vin rozroblyaetsya zdebіlshoy not for off-road. And as if it would be a Ferrari from scratch, and not a re-engineering version of the current car. The British magazine Autocar found out that Purosangue will be seen on a modular platform, razroblenno for podtrimki avtomobilіv s front and srednіm raztashuvannym dviguna, scho is unfamiliar for the segment poshlyahovikіv. This layout is most associated with low sports cars. So, the latest set of electronics and other additions are self-explanatory. Ferrari technical director Michael Lighters said that the model will not be similar to any other market. Technical specifications are also unavailable and, better than everything, stink is not yet complete. Ferrari can beat the stability of the 8- and 12-cylinder engine on a vibir. Incorrect bits also point to the hybrid version, which is connected by the module, based on the not yet presented V6 engine. The new drive will be standard, as is the automatic transmission.

Purosangue won't be the first favorite Ferrari, Ale will be one of the largest family models, if the company ever let you in. Vlasniki can ride on New Skin Day of the Tsiliy Rik. Otzhe, vіn bude zruchny for water and for the passenger. Engineers rely on electronic marvel (for example, suspension with electronic regulation). Pozashlyahovik otrimaє all functions, like scoring purchases in a modern luxury car, like a projection screen and a modern information and distribution system.

The problem of shaving the timing belt and the farther side of the valves was known to the wealthy of Lady Kalini. Improved Grant, on the thought of a lot of buyers, pozbulas tsієї problems.

Ale, all the same, do not get through the fight against the Danes. Therefore, it is recommended in advance to find out about those valve bending for Grant 8 valve and 16 valve, and models with which engine is the most reliable operation.

On which Grant engines does the valve bend when the timing is shaved?

Granty's Nine Vlasniki argue that not all 8-valve engines are problematic. Zokrema komplektatsiya "Standard" is equipped with a defiantly powerful power unit and do not bring serious damage to your future sergeant.

Breakdowns cannot be blamed when looking around and diagnosing a car. However, for the unit 11186 (before 21114), periodic checks will not necessarily be a preventive approach.

The features of 11186 dvigun are a change in the noise of the robot, a low heat of the fire and an increase in the pressure. Ale krіm resurrected the additional operation of the power unit by removing and working problem areas: a new connecting rod-piston system. Її main power - ce relieved the weight, reach as a result of the shortening of the pistons. As a result, the change in space did not allow practical and safe expansion of the mechanisms.

Why Grant 8 valve valve?

The breakdown procedure itself is also no less important for repair. Having understood, like the peasants themselves, they are more shy until they are weaker, the hairdresser can give them more respect, or turn around for help to fakhіvtsіv.

Maystry after the diagnostics are carried out to improve the service and help to eliminate the numerical reasons for shaving the timing: jamming of the pump, rollers, camshaft or crankshaft. The very process of valve replacement follows the following scheme:

1. Shave the timing belt.

2. The camshaft is geared.

3. Continue wrapping the crankshaft (passing the flywheel wrap).

4. Pistons blow over the valve openings at the moment of shaving.

In such a rank, the valves are closed, and in the future the stench will demand a full replacement. It is also possible to recognize Lada Grant 8 valves and valves from fakhivtsiv, which are used at the service station.

Aje breakage does not obov'yazkovo hit the leather vlasnik vіtchiznyany car. There is a problem at the vintage vipadkas, if the car driver does not give enough time to service the car. The first reason for this is the lack of good-natured exploitation.

In some cases, it helps to change the belt for a larger price: the factory component may not be suitable for the necessary minds of the need for advancement and exploitation. The strength of the tightness is to blame, depending on the statement of the recommendation of the pickers. Therefore, independent regulation can only worsen the situation.

Turn to fahіvtsіv so slіd when the first signs appear, yakі can indicate the onset of the opening of the belt. There may be slight noise from the timing drive. The same wine and vkazhe for possible wear or private wedge or pompi.

All these factors are critical and can lead to the need for expensive repairs, and in extreme cases to the evacuator’s winding up, as if the water at the time of the opening was broken beyond the border of the city. Vlasnik Granty needs to take care of all the nuances and solve the least problems as soon as they appear.

Before buying, either after, or later, it’s too early for AvtoVAZ to praise the news: “Does the valve on the Lada Grant bend when the belt is opened?”. With the first problem, motorists are not easily caught, even the previous models often sinned with an unacceptable defect. When the timing belt was broken, the valves bent especially on the 16-valve engines of the “twos” and Prior.

As you can see, Lada Kalina is based on Lada Grant in combination with її nadіnymi dviguny and do not bend with valves. But, unfortunately, only the ladies of Lady Grant in the “Standard” configuration can calmly calm down. And the axis of the Lada Granta "Norma" is equipped with an eight-valve engine with a lighter connecting rod-piston mechanism, and in such an engine, when the timing belt is opened, the valve constantly checks the pistons. After such zіtknen repair, of course, do not get lost. The beginning is marvelous - the same may be due to the characteristics of the engine to vary the design. But everything is explained by the fact that on standard 8-valve engines, the pistons may be damaged for the valves and when the belt is opened, the stench does not stink. And the axle is still moving, but with a lightened connecting rod and piston group, equipped with shortened pistons, in which there is simply no place for burial. Therefore, having opened the timing belt, it is not uncommon for the valve valves to follow.

The same problem may dvigun Ladi Priori, though they have a wide belt and the ability to grow to a minimum. The great achievement of the operation of this car by showing that shaving the timing belt is rarely seen, and then when the cob is in tow, or from the shtovhacha, which, in principle, categorically hindered the robit, the fact that when the engine is started in such a situation, the pressure on the rozpodremny shaft will depend kіlka rіztsіv, scho to bring to the sum results.

As if it wasn’t there, a car enthusiast of goiter stitches behind the camp of the timing belt wind in that fall, as if the pistons could be buried for the valves. Prevention has not hurt anyone yet, and the axis will be engaged in the repair of everything that can be done on the highway - it’s not busy for receptionists.

Dvigun Lady Granty 8 valves volume of 1.6 liters at the current moment is the most popular among buyers of a budget sedan. The design of the engine is well known not only in the official service, but in any garage. Therefore, the repair and maintenance of this motor is not difficult and costly. Today's report will talk about giving the report engine.

Gasoline power unit Lada Granta VAZ-11186 87 HP with a working volume of 1.6 liters, it develops 82 kine forces for the replacement of the VAZ-11183 injection engine. Increase the tightness and efficiency of the power unit in the distance of a new lightened piston group from Federal Mogul. Obviously, the motor does not look like an enchanting dynamism and low vitreous paliva, but also a remarkably simple design and maintainability allow you to talk about inconsiderate options for our smart minds of exploitation.

As for the attachment of the technical part, then in the basis of a chavunny block of cylinders, an aluminum head, an aluminum cylinder head cover, a steel pan of the engine crankcase. At the drive timing Lada Granta 8-cl. varto belt. The eight-valve timing mechanism does not have hydraulic compensators, the valves are rarely adjusted, but the process is smoked. It is necessary to pick up the "p'yataki" of various comrades and lay them between the camshaft cams and the bottoms of the shtovkhachiv flasks. The first time such a procedure is carried out at the so-called "0" zero maintenance, after 3000 km of driving.

odvіchne food gnіt chi valve on dvigun_ Grant VAZ-11186 when shaving the timing belt? Vidpovіd is unambiguous, when shaving the belt valve bend! As a bet, a 5-speed manual gearbox is added to the motor, there are no other options.

Timing diagram Lada Granta 8 valves

• 1 - gear pulleys of the crankshaft
• 2 - gear pulley of the cooling radiator pump
• 3 - tension roller
• 4 - rear lens cover

One more feature of the motor can be called a water pump (pump), which wraps around the same timing belt. Tobto, in the case of a cold leak, or a characteristic noise / whistle / hum in the timing drive area, re-checking the obov'yazkove belt. If the pump bearing loosens and the belt flies, then replace the water pump body and the belt will have to go over and the cylinder head, causing the valves to bend.

Nourishing tsіkave and hvilyuє bagatioh - bending the valve on the car Lada Granta when shaving the timing belt ...

physics of the process

Let's explain what a timing belt is. Timing belt - tse gumovy closing belt, with notches on the inner side, for synchronizing the crankshaft of the engine. Zastosovuєtsya when vikoristanny pass transfer.

When the timing belt is shaved, the shafts rattle in such a position, in which it becomes a shave, and the crankshaft continues to rotate by inertia and the pistons hit with an effort on the valves, according to them, they were at the same moment open. As a result, the valves bend (div. Malyunok). Absolutely unimportant, the transfer became tse chi nі, and the number of revolutions could not be significant.

On the front two, the bloody valves are especially visible.

Causes, through yakі vіdbuє shaved

• the most common reason for shaving the timing belt is jamming the pump
• shaving through the wear of the belt, incl. through the trash
• jamming of rollers, rozpodіlnyh valіv, cloned
• and etc.

As a result of all of them, it is possible to guard the advance:

You can see dents on the pistons

Is the valve bending on Grant?

So, since different configurations are installed on the Lada Granta (it is reported about the engines), then it will be different for food.

On the “standard” configurations, 8-valve engines of 1.6 liters are installed, which can still be installed on Lada Kalina. Such engines have already gone through testing for an hour and have shown themselves good in robots - when the timing belt is shaved, the valves are left in a normal state.

On the “norm” configuration, an 8-valve upgrade with a lighter piston group was installed (these are also installed on Kalina). Here the problem of zustrichi pistons and valves when shaving the timing belt is not solved. It is worth noting that in the destruction of such engines, the special screws were destroyed, and with the lightening of the SHPG, the pistons became thinner and the destruction of the place was not lost.

Vlasnikov "luxury" please also not see - їх 16 valves when shaving the belt, the valve and the piston are also fastened. The truth is that such engines have less vipadkіv, but alerizik є. The main reason for shaving on such engines is jamming of the pump, tension and support rollers.

Rizik is a particularly great yakcho...

Varto does not marvel at the car, as if she herself will tempt you to marvel at her with a great and stained repair. At AvtoVAZ, it is more common to change the timing belt, keep rollers, tensioners, etc. behind the camp, so that you periodically carry out technical maintenance. We want the plant and give a guarantee for 120,000 km on the belt, which is a big risk. It’s better to follow him more often, and spend time in advance, until you happen to spend money on a major overhaul of the engine.
