In this article, you will learn how to adjustvalve on the VAZ 2107 with their own hands, without recourse to the specialists of the service station. Despite the fact that this procedure is relatively small, it is desirable to perform it every 10-15 thousand miles. Yes, it is not costly, but you lose a lot of time. It is worth noting that the setup procedure itself will take no more than 20 minutes. And when you learn, you can even do it in half the time, even in the field. With the necessary tools, of course.
So, to begin with, you need to sort out a littlethe internal device of the engine, or more precisely the head of the unit. The VAZ 2107, like the rest of the classics, is equipped with an 8-valve motor. In other words, in each cylinder there are two - one intake, as much to release. With the help of valves the combustion chamber closes completely for a while, while the working stroke of the piston is made. As a result, the engine's power is increased, it turns from two-to four-stroke.
This is the main purpose of the valves. Now a little about how they are set in motion. And it happens by means of a camshaft, which is connected by means of a chain with engine crankshaft. It is worth noting that the crankshaft makes a 360-degree turn, and the camshaft passes through this gap only 180 degrees. In other words, it rotates twice as slowly.
When there is a gap, the enginestarts to work incorrectly. The reason is that the valve does not open at the moment when you need to perform an intake or exhaust stroke. As a result, the car VAZ 2107 either works intermittently, or simply stalls and does not want to start. And it happens exclusively on a hot engine, on the cold there are no remarks on the work.
If suddenly noticed such symptoms, immediatelystart the tuning procedure, because the further operation of the car becomes simply impossible. You can make adjustments even in the field, there is nothing complicated in it, you just need to know the order in which the adjustment is done. And, of course, you can never do without a tool, it should always be in the glove box. Yes, it is there that everything you need will fit, the tool takes up a little space.
Before adjusting the valves on the VAZ 2107,should acquire the necessary tools. So, you need to have a metal feeler. Its thickness should be 0.15 mm. In stores, he sells for a ridiculous amount, so that they do not have a problem. In addition, the plastic handle of the probe has a small "guide" - the scheme for setting. You will also need a standard set of tools - screwdrivers, keys.
Of the keys you need sizes 10, 13, 17. And the first is preferably tubular type, it is much more convenient to unscrew the nuts that attach the cylinder head cover. And try not to lose the puck. Before adjusting the valves on the VAZ 2107, you need to remove everything that prevents the dismantling of the cylinder head cover. And in some cases, by the way, you may need to replace the gasket. The rest of the keys of the requirements are not special, it is desirable only that they are long. The bigger the lever, the better to unscrew the nuts. Also, you need a special key on the 38, which cranks the crankshaft. However, if in your car there is a "curve starter", the need for a key disappears.
And now about the same order of adjustmentvalves VAZ classic series. First, of course, remove the head cover, if necessary, the air filter housing. This is the case if the carburetor injection system is installed. Turn the crankshaft until the tags are aligned. There are only three of them, you need to put them on average. In this case, the notch on the pulley of the camshaft drive must be installed opposite the casing protrusion. Now loosen the nuts on the sixth and eighth valves.
The bill comes from the front of the car, notforget. That's how to adjust the valve VAZ 2106 and other cars of this manufacturer. It is necessary that the probe come with a slight friction. He should not freely penetrate the gap, but it is unacceptable for him to come in with excessive force. Checked, tightened the nuts, then tried again to install the probe to make sure the correctness of the adjustment. Everything okay? Go further, rotate the crankshaft constantly 180 degrees (between adjusting each pair of valves). The next - the fourth and the seventh. Then - the first with the third, and the latest - the fifth with the second.
Now you know how to adjust the valveon VAZ 2107 correctly, the whole procedure will take no more than 20 minutes of time. The only clarification - try to conduct the procedure every 10 thousand km. mileage. In this case, you will save the motor from excessive wear, and you will be insured against the fact that the phases of the gas distribution are violated.
