The article will talk about the ignition system of the VAZ-2109 car. The distributor, also known as the distributor, is literally in the "heart" of this system. Such designs were installed exclusively on the carburetor engines of the "nine". On injection motors, a plug is installed instead of a distributor. The distribution of the spark to the candles occurs in such systems in a slightly different way.

The most common faults

Do not rush to panic: the replacement of the distributor on the "nines" is extremely rare. This mechanism has a high resource. Many cases of distributor breakdowns require the complete replacement of faulty elements. Treatment can only be a violation of the contacts in the plug for connecting the sensor itself, which operates on the Hall effect. Very often engine oil gets inside the ignition distributor. A great example, it can be seen literally on every "nine" and "eight". The distributor is fastened directly to the cover that covers the valves. And they work only on the condition that engine oil constantly flows on them. If you suddenly dismantledthe ignition distributor, removed the cover from it, then the slider, and, having removed the protective screen, found that there was a lot of engine oil inside, we can conclude that it got inside through the stuffing box located on the shank of the VAZ-2109 distributor. The distributor can fill with oil for several reasons. We will try to consider them.

Reasons for oil in the distributor housing

The reason is that there is a small hole at the very base of the carburetor that gets clogged. It is necessary for crankcase ventilation. Consequently, when the engine is idling, a very large air pressure in the crankcase begins to occur. Thus, the oil is squeezed into the distributor. The price of the entire mechanism is on average 1000 rubles. In this case, the gland is destroyed. Therefore, for a normal repair, you need to clean the air vent from dirt. It is advisable to do this with compressed air. It is also necessary to change the gland on the shank. The second, most common reason why oil enters the distributor housing is the destruction of this particular seal.

What to look for when carrying out repairs

When repairing, be sure to pay attention to the distributor cap. There should be no dents, cracks, chips, breakdowns, as well as traces of oxidation on the contacts. Otherwise, make a complete replacement of this element. And also pay attention to the graphite rod, which is located in the center of the distributor capignition. It should move quietly, under the action of a spring, return to its original position. The operation of the internal combustion engine directly depends on the condition of the distributor cover. If there is damage to the graphite or copper contacts, it is easier to completely replace the ignition distributor cap. In reverse order, you need to assemble the entire distributor. Please note that the roller and all rubbing elements without exception must be lubricated with clean engine oil. But do not apply too much lubricant to these elements. That's all, the repair of the distributor is completed, now it can be installed in place.

What to consider before removing the distributor

Before you disassemble the distributor, you must remember how the armored wires are installed on its cover. And on the "nines" the designation has only the first wire. It is worth noting that the distributor cap is a very important element. The normal functioning of the engine depends on its condition. Even a small crack will lead to the fact that the engine cannot be started. Other wires will need to be installed independently. Look from the side of the left wing and count counterclockwise - first the first, then the third, the second, then the fourth. If you need to replace the cover or runner, then you do not need to completely remove the ignition distributor. But if it is necessary to repair the entire distributor, then it will be necessary to completely remove it. Disconnect the high-voltage wires, as mentioned earlier, and then perform all the manipulations necessary todismantling.

Conclusion

In conclusion, I would like to note that many problems in the ignition system give out symptoms that are very similar to those that are relevant for fuel supply. You can not immediately determine whether there is a breakdown in the carburetor or in the switch, coil, distributor. Only a deep analysis of all the components of the VAZ-2109 car, the distributor of which was considered in the article, will give an idea of which element has really failed. The most important thing when operating a car is to correctly set the ignition timing. On the "nines" this procedure is very simple, it is enough to set the camshaft and crankshafts according to the marks. The distributor housing is placed in only one single position, with its help it is possible to carry out only a slight adjustment of the ignition timing on the VAZ-2109. At the same time, the distributor rotates in the right direction on its axis.
