Replacing the timing belt VAZ 2110 16 valves. VAZ 2110: repairs

Replacing the timing belt VAZ-2110, 16 valves or 8, is made according to one scheme. The only difference is that in the first case, the two rollers and the belt are slightly longer. In fact, the engine can be the same, and the number of valves per cylinder is different. What can I say, the motor of the eight liked motorists and the manufacturer. And it turned out to be a good one, that they put it on dozens and on models 2113-2115, and even modern "Lada Granta" go off the assembly line with the same exact engine. Constancy is, undoubtedly, a sign of high skill. But there are also advantages - almost all elements are interchangeable.

Timing Belt: features

Drivers of the "dozen" with 16-valve motors like and "hate" their cars at the same time. The reason is quite simple - although the old design as a whole, it has enough small things that make it unique and more modern. Yes, and like some 16-tiklapannye motors with breakage of the belt to deteriorate. Valves simply bend, destroying at times even the head of the block. But this happens, fortunately, not on all motors. Some put pistons with special notches - cycling. In this case, the replacement of the timing belt VAZ-2110, 16 valves if the engine and the pistons have recesses, can be carried out even after the breakage. There will be no consequences for the cliff.

This is a kind of niche for the plates of the valves. When the belt is torn, the valves all fall down. Pistons continue to move (imagine if this happened at a speed of over 90 km / h). Due to these niches there is no unexpected meeting of the valve with the piston, the fate protects them. But more modern, modernized engines, not only are not afraid of a cliff, but still have a relatively high resource. What to say, in the cars of "Lada Priora" the belt is wider than twice, and its resource (according to the manufacturer) is about 200 thousand kilometers.

Is it difficult to replace?

If you have experienced the replacement of the timing belt on an 8-valve engine, then you have the skills in this matter. Therefore, you do not care which motor you need to service. Yes, the strap 16-tiklapannoy ten is longer and the roller is already two! So what? Do not forget that the labels became the most for one thing. And getting lost in three marks is very difficult, and sometimes impossible.

Of course, replacing the timing belt, 16 valves if in the engine, requires particular accuracy. If the camshafts rotate unintentionally, the valves can not open and close in a timely manner. Therefore, all motor strokes will be violated. But if you pay attention to the 8-valve engines, then in them there will be similar changes. Strongly do not worry, you can replace it, especially since it's a dozen, which is very simple in the device.

What else to change with the belt?

As already mentioned, it is necessary to replace the rollers. There are two in the drive - one serves to tension the belt, and the second to hold it and prevent it from sliding off the pulleys. The first (tension) is located on the axis in the form of an eccentric. When the outer part is rotated, it is displaced, thereby tensioning the belt. Both the first and second, the timing belt roller, it is necessary to change. As in the case of jamming, excessive belt wear or excessive breakage occurs. Sometimes even the replacement of the timing belt VAZ-2110, 16 valves, if its motor, will not help, since it is quite possible to crush the cylinder head.

And now you should pay attention to the belt resource. If the car is not five years old (which is relevant only for the "dozens" analogues under the Bogdan brand), then the belt is replaced every 55-60 thousand km. But if the car is older than five years, it is better to reduce the frequency by 15-20 thousand kilometers. Great wear and tear on all systems and components of the car makes you aware of yourself, because of this the resource of such a "gentle" belt is reduced. But the pump has a resource of about 90 thousand. It can be concluded that every second replacement of the timing requires a new pump. And still need to pay attention to the antifreeze - there are many additives in it, which after 80-100 thousand runs are evaporating.

Preparing for replacement

On the VAZ-2110 repair should be carried out from the right side of the car. And you need to remove the wheel to get to the crankshaft pulley. But first, from under the hood, remove the generator belt and the protective cover that covers the gas distribution compartment . You do not need them yet. Then lift the right side and remove the wheel. Look at the pulley and wonder how to keep it from turning. You do not need to pawn anything! Since such a procedure is done on carburetor motors, it will not work with an injector. The generator drive pulley has teeth that are necessary for the crankshaft position sensor to work. And if you break the integrity of this pulley, the engine will not be able to work properly.

How to keep the crankshaft from turning?

But to change the timing belt is without helpers is very difficult. To keep the crankshaft from turning , you can use two methods. The first, the most secure and humane, is that one person is sitting in the salon. He must push the brake pedal with all his might. Thus it is necessary to include the fifth speed. Only in this case the crankshaft can be kept from turning. The second method also requires an assistant, you need to install a flat screwdriver into the inspection window of the clutch housing. And so that it rested against the space between the teeth of the crown of the flywheel. Needless to say, a screwdriver must be massive, small ones do not fit for this purpose. That's all, when the bolt on the crankshaft is twisted, and the generator pulley is removed, you can dismantle the old timing belt, rollers, and install new items. In other words, the replacement of the timing belt VAZ-2110, 16 valves or 8, is carried out on the same type of scheme, the general requirements are the same.

Setting labels

Do not think that you can just take off and put the belt. In any case, it is necessary to check the coincidence of marks on all pulleys. First, before installing a new belt, put both camshafts correctly, according to the marks that are on their surface. Secondly, turn the crankshaft until the tags on the pulley on the oil pump side match. Third, for a more precise adjustment, perform the crankshaft installation so that the mark that is on the flywheel is in front of the clutch housing inspection window. Only after this, you need to put on a belt and pull it. After installation, always rotate the crankshaft by 360 degrees and check if all the marks match? That's so easy on the VAZ-2110 repair happens. And it does not matter how many valves in the motor.
