VAZ 2109: device trambler and replacement

The article will consider the car VAZ 2109, the device of its trader is given. Normal operation of the trambler is a guarantee of stable operation of the internal combustion engine. The reason is that by means of the distributor the spark is applied to the candle electrodes. And this happens not only when the car is moving, but also when idling.

What does a spreader for?

It is extremely important for the distributor to operate normally for ideal dynamic characteristics when the engine rapidly accelerates. The function of the ignition distributor is that it corrects the timing of the ignition timing. In other words, he chooses the right moment to apply a spark to the candle electrodes. And this moment depends on certain factors, including the crankshaft speed, the load on the engine, and many others. It is also worth noting that it is necessary to correctly distribute the spark across all the candles. This is part of the task of the ignition distributor, that is, the trambler. If the engine on the car VAZ 2109, the device whose trampler is discussed in the article, starts to twitch, the machine does not start or it does it with difficulty, then, most likely, it is necessary to repair the distributor itself. This process is not complicated, you do not need the education of an electrician, it is enough to stick to a small instruction.

Treadmill construction

This is the main element of the entire ignition system. It is necessary to regulate the control and transmission of low-amplitude electrical signals from the Hall sensor to the electronic switch. And also distribute the high voltage to the spark plugs in strict sequence. And this sequence depends on which cylinder the ignition stroke should take place. On the car VAZ 2109, the device of which is almost exactly the same as the same node on the "classic", the contactless ignition system is installed . Contact types of systems have never been used on this series of cars. They were used on all early models of VAZ cars. But such a system went into oblivion, as it has many shortcomings. The main thing is the presence of a contact breaker-distributor. The functions of this mechanism in a non-contacting ignition system passed to the Hall sensor. It is worth noting that the work of both systems is almost the same. The only exception is the design of the interrupter. Here is a simple device for the VAZ 2109 trambler. The carburettor is located in the power supply system, then the ignition distributor is the main element. If the car is injected, then the trambler is missing.

Design Features

In addition, the VAZ 2109 trampler, whose device is discussed in the article below, includes a vacuum and centrifugal ignition timing regulators. In addition, there are several more elements that contribute to the normal operation of the distributor. In addition to the vacuum corrector, the Hall sensor, the centrifugal regulator, there is a plastic screen that protects the inside surface of the distributor from dust and dirt. The slider, which is fixed on the rotor of the ignition distributor, has a constant resistance in its design. Its value is about 1 kOhm. Also there are thrust and lock washers, several adjusting, supporting plates and sealing rings. All this is assembled in a single aluminum casing. At one end, the lid is fastened using two bolts. Of these elements is a trampler VAZ 2109, a device, photo and design of which are given in the article.

How to determine if the trambler is broken

Determine the malfunction of the electronic ignition distributor is quite simple. Starts to twitch when driving a car. And there are no other prerequisites. In other words, there is quality fuel in the tank, the gasoline pump is in a normal state, the carburettor is working properly. The engine starts to trip when the car is picking up a certain speed. Often the reason for this is the oiling of the contacts that are on the body of the trambler. Also, the engine may not start. There is a knocking of the piston fingers during speed dialing. If the speed is extremely slow, the consumption of gasoline increases, then there is a breakdown of the ignition distributor or some of its components. The cover of the VAZ 2109 trampler may collapse.

What can fail?

And most often burns the slider, which distributes high voltage to the electrodes of candles. The contacts located directly in the plastic cover can also burn out. If the engine does not start at all, then it is possible that the central contacts in the cover of the distributor VAZ 2109 are destroyed. The device of the trambler is such that it can not be avoided without using such contacts. The Hall sensor can also be damaged. Very often the bearing of this sensor is blurred or its destruction occurs. Even the slightest crack in the cover of the ignition distributor can cause the engine to not start or operate with interruptions. It is possible that the plug to which the Hall sensor is connected has very poor contact.

Removal of the distributor

This manual will be required if you need a replacement for the VAZ 2109 trampler. Also, in order to make repairs, it is necessary to remove the ignition distributor. To do this, you must first disconnect the negative terminal from the battery. Then - disconnect all the armored wires going to the ignition distributor cover. Also, the hose that goes from the vacuum corrector to the carburetor is disconnected. After that, it is necessary to detach the bracket that holds all the wires. To do this, unscrew the nut. Note that under it there is a washer, which is very important not to lose.

Setting the distributor

Please note that the car VAZ 2109 install the trampler can only be in one position of its rotor. Therefore, before removing the trampler on the VAZ 2109 from the camshaft, you do not need to apply any marks. Simply unscrew the three nuts that secures the body to the cylinder head. But before this, it is necessary to disconnect the plug that connected the Hall sensor to the switch.

If you do not remove the timing belt, and only work with the ignition distributor, then when installing the trampler, you do not need to put the crankshaft on the marks. The design of the ignition distributor drive on the "nine", as well as the "eight" and carburetor "tens" differs from that used in the cars of the classic series. The distributor can not be put somehow wrong, it becomes in one position only. In this case, the contact of the slider will always be in the position in which it is necessary to be. On how to set the trampler on the VAZ 2109, it is not worth much to say. The main thing is to put marks on distribution and crankshafts correctly.

Beginning of disassembly of the trambler

First, unscrew the two bolts that make the cover fasten to the distributor body. Then take out the slider by pulling it up. Pay attention to its condition, it should not have any rust, no damage, no signs of wear, no burning. At the same time, in its usual position, the slider should be firmly attached to the rotor of the trambler. A good fit is provided by a small leaf spring. In the event that there was a weakening or whether it broke down or deformed, you must completely replace the entire slider. The cost of this element is small, not more than 50 rubles, so there will be no problems with it. Please note that all wires of the VAZ 2109 trampler must be disconnected from the power system.

Check runner and further dismantle

To make sure the integrity of the slider, it is necessary to measure the resistance, which is between the contacts of copper on it. The resistance should be about 1 kΩ. Next, you need to dismantle the plastic screen to protect it from dust. Then a terminal is obtained, by means of which a low voltage is transmitted. To do this, it is necessary to unscrew the bolt that secures it. The screwdriver needs to tighten the holder and take out the wire. Then, two bolts are twisted, by means of which the support plate of the non-contact Hall sensor is fastened. After that you can remove it. A circlip is pulled out, it is quite possible that it will take a lot of effort. But you can not worry, it's unlikely to break this knot.

After it is necessary to unscrew the two bolts that fix the vacuum corrector, without it the VAZ 2109 tramper will not be able to work. Its device is such that it makes a change in the ignition timing, analyzing the work of the motor. Using a screwdriver, it is necessary to pull the pull of this corrector with the support on the plate.

End of disassembly

After this, it is possible to completely remove the vacuum corrector from the ignition distributor housing and pull out the support plate. In the event that there are scuffing, tears, or excessive wear on the hub, it is necessary to completely replace this element. Then it is necessary to dismantle the snap ring. After this, the washer is removed, which is located directly behind it on the platen of the ignition distributor. The pin that fastens the clutch is pressed against the spring ring. It must necessarily be removed. In the event that the sealing ring has wear or has become hard, or even completely torn, change it to a new one. For knocking out the pin from the coupling, it is necessary to take at least a small nail, or better - a thin prick. Then disassemble the plate on the centrifugal regulator. Check the rotation of the weights of this regulator on the axes. If it is heavy, then it is necessary to remove the retaining rings and these weights. Carefully clean all openings and lubricate it.

If you need to replace the interrupter, you need to unscrew the two bolts that secures it, then remove it from the support plate. Note that in some ignition distributors, the sensor can be fastened with rivets. In this case, the replacement of this element must be carried out together with the plate on which it is located. Here's how to remove the trampler on the VAZ 2109, as well as to conduct its complete disassembly. Assemble in the reverse order.
