Adjusting the distributor vaz 2106. Contact ignition system

Not only the power and dynamics of the power unit, but also the consumption depend on how competently and skillfully the ignition setting of the VAZ-2106 is performed. Incorrect ignition operation can be detected by the following points:

difficult start;

insufficient engine power;

excessive consumption;

unstable mode XX;

elevated temperature;

detonation after shutdown;

when you sharply press the "gas", a characteristic knock of the fingers appears.

Setting the ignition on the VAZ

Depending on what type of ignition is installed on your model, the system setup has some features. At the same time, the principle of performing this operation for all modifications is similar. The ignition adjustment of the VAZ-2106 is carried out in 3 stages:

UZSK - calibration of the contact angle in the closed position.

UOZ - advance angle adjustment.

Performance monitoring on the move.

Ignition contact angle adjustment

For work we need:

a set of keys, including a special key for the crankshaft;

• set of probes for VAZ-2106;

  electronic tachometer.

If your model uses a classic or transistor-type ignition system, the ignition setting is performed in the following order.

We dismantle the cover from the distributor and clean the contacts with a needle file so that they close tightly with each other. If necessary, bend the fixed element.

By rotating the crankshaft with a special key, we set the maximum clearance. In the absence of a key, you can perform this procedure by pushing the car, having previously engaged 4th gear.

After the maximum clearance is set, unscrew the screw of the bearing plate.

Then, with a plate of 0.4 mm, it calibrates the gaps, and then we fix the position by screwing in the screw.

We control the distance between the electrode plates by 0.35 and 0.4 mm. In this case, a thin probe should pass easily, but a thick tool should not. Put the distributor cap in place.

We start the engine and check with the help of the UZSK tachometer. It should be 55°±3°. Performs calibration if necessary.

Adjusting the ignition timing



To perform this procedure, there are several options, the best are the following:

• using a stroboscope;

  with a light bulb;

  by spark;

- the fastest and most accurate way to calibrate if this device is available. First you need to connect the device to the network of the machine. Then you should remove it from the distributor and plug the pipeline of the octane corrector. After this, we warm up the engine to the recommended temperature. After that, we loosen the fastening bolt of the distributor and direct the strobe beam to the pulley area. At a stable speed of XX, by rotating the distributor housing, we set the first pulley mark against the second division, which is located on the gas distributor cover. Having adjusted the desired position, we fix the distributor body by tightening the fixing bolt.



Light bulb setting performed in the absence of a stroboscope. The adjustment is made using a twelve-volt bulb, to which 2 wires are pre-connected and a special key for the crankshaft.

First, by rotating the crankshaft, set its mark opposite the zero division on the gas distributor cover.

Connect one wire of the light bulb to the coil through the cable coming from the distributor, and the other to the body ground.

Remove the central cable of the distributor and connect it to ground.

Slightly unscrew the mounting bolt of the distributor housing.

Turn on the ignition system, the lamp should be on.

Turn the distributor housing clockwise to set the position at which the control lamp goes out.

Following this, move the housing back until the lamp lights up again.

Fix the distributor with the bolt.



If your model has a thyristor or transistor circuit for the VAZ-2106 ignition switch, this adjustment cannot be made using a light bulb due to the fact that the voltage available at the distributor contacts may not be enough to turn on the lamp. In this case, the adjustment should be made using a diode probe or a voltmeter.

Spark control is made on the basis that a spark appears when the contacts open. Pre-install the crankshaft in a position in which its mark coincides with the first division on the gas distributor cover. In this case, the distributor slider will be opposite the power cable of the 1st cylinder. Pull out the central cable of the distributor and place it at a distance from the ground within 5 mm. Unscrew the distributor mounting bolt and turn on the ignition. Rotate the body clockwise 25-30 degrees. After that, slowly move the body back and at the moment a spark appears, fix the distributor.



Hearing adjustment should be carried out only in exceptional cases, when the above options for one reason or another could not be implemented. First, turn on the engine, and then loosen the fastening of the distributor housing. Rotate the housing to set the maximum speed of the motor. After that, turn the distributor slightly clockwise and fix the housing with a bolt. This is quite likely to make a big mistake, however, this will be enough to get to the nearest service station or your garage, where you can fine-tune.

Ignition health monitoring

The results of the ignition setting must be tested while the machine is moving. Before that, preheat the engine and after accelerating 45-50 km / h, turning on the 4th gear, vigorously press the “gas” pedal. With the correct adjustment of the ignition at this moment, characteristic pops should appear for a short time (1-2 seconds) and immediately disappear as a result of detonation, followed by an energetic increase in speed. If this does not happen, turn the distributor housing 1 position counterclockwise. When detonation continues for more than 2 seconds, the housing must be rotated clockwise by 1 notch.

I must say "how to set the ignition on the VAZ 2106" - this is a fairly common question. About how to do this, and what is needed for this, in the article.

The content of the article:

To begin with, it is simply impossible to set the ignition on the injector. This system has an engine control unit, which, judging by the indicators from the phase sensor and the crankshaft position sensor, supplies voltage to the ignition system. Therefore, it is impossible to adjust the ignition on the injector. Not at all.

How to understand that you need to set the ignition

There are several indirect signs worth looking at. Of course, if the engine does not start, then setting the ignition is the first thing that comes to mind, unless, of course, the candles are wet. Consider the main symptoms that indicate the need to install the ignition.

Signs that an ignition installation is required:

• Increased fuel consumption. Of course, this may be due to improper adjustment of the carburetor, but it also happens. For example, with late ignition, the dynamics of the car drops, to achieve the same acceleration, a larger amount of combustible mixture is required.
• Loss of dynamics. With late ignition, the explosion goes after the piston, which has already gone down under the action of the flywheel inertia.
• Silencer shots. When the explosion occurs in pursuit, the expansion of gases takes some time. If the piston has already reached bottom dead center, then the exhaust stroke is next. This means that part of the fuel explosion will be transferred to the exhaust system, hence the pops.
• Increased engine noise. Installing the ignition on the VAZ 2106 will be required if the engine begins to noticeably "rattle" and shake. In this case, the piston is still going up, and the explosion is already happening towards it. This makes his work very hard, unpleasant to the ear, immediately noticeable.

How to set the ignition on the VAZ 2106 - procedure

First, you need to set the ignition label. The crankshaft can be rotated either with a ratchet or with a special key for a nut. On the front cover of the engine and on the crankshaft pulley there are ebb and flow, the combination of which corresponds to a different ignition timing:

• The first mark in the direction of travel is 10 degrees ahead of the ignition angle. Angle lead is a correction for the burning rate of the fuel. So, 10 degrees is the mark for 72 gasoline.
• Next comes the middle mark - ahead of 5 degrees. It's for 80 petrol.
• The last, short mark is a lead of 0 degrees. This means that the mixture will ignite exactly at the moment when the piston is at top dead center.

After the installation of the ignition mark is completed, you must immediately set the required clearance in the contacts, of course, where they are. To do this, remove the distributor slider and unscrew the breaker fixing screw.

Before setting the gap, it is advisable to clean the contacts with sandpaper (600-800)

The gap between the contacts of the breaker in the open state should be 0.35-0.40 mm. To do this, you will need a flat probe.

Well, now we go directly to the ignition installation of the VAZ 2106. We unscrew the distributor mount (nut by 13), after which we pull it out of the housing.

Now you need to insert the distributor into place, given a few mandatory points:

• We set the top dead compression stroke in the first cylinder according to the mark, respectively, at this moment the spark should appear in it. In order to catch this moment, we put the cover on the distributor and mark the place where the armored wire enters from the candle of the first cylinder. Now you need to remove the cover and set the outer contact of the slider exactly opposite the mark. That is, at the moment when the piston is at top dead center, a spark is supplied from the central wire of the distributor through the contacts of the slider to the armored wire from the first cylinder.
• Next, to set the ignition to 2106, you need to draw an imaginary line between the roof latches and install the distributor in place so that this line is parallel to the engine block. It should be said right away that it will not work to get into the slots of the drive the first time, you will have to twist the case a couple of millimeters. This is not scary, because the ignition installation requires subsequent adjustment. It is important that the distributor fully sits in its place so that it rests on the block. Next, we pull it into place.

Ignition adjustment VAZ 2106

Setting the ignition is half the battle, because then it needs to be adjusted. After the engine is started, it is necessary to warm it up, accelerate it to 40 km / h in third gear, then turn on fourth and press the gas pedal about halfway, maybe three quarters, but not to the floor. There are a couple of scenarios for the development of events, each of which requires its own solution.

• A short-term detonation that disappears after a couple of seconds. It's okay, that's how it should be. If it passes within 4-5 seconds, then subsequent ignition adjustment is not required.
• Long detonation. This indicates that the ignition is too early. In order to make it later, you need to stop, loosen the fastening of the distributor body, holding it with your hand, and then turn it one division on the body towards the “+”. Then perform the same operation if the detonation lasts longer than the time indicated above.
• No detonation. This is also not very good. In this case, you need to stop and turn the distributor in the direction of "-".

How to set the ignition on a VAZ 2106 video:

All owners of domestically produced cars face the need to adjust the ignition. Especially when it comes to older vehicles. This material will help you find out how the VAZ 2106 car is and in what cases it may be required.

[ Hide ]

When is ignition required?

There are several symptoms by which the car owner can determine that it is necessary to adjust and set the ignition breaker:

1. Inability to start the engine.
2. Increased fuel consumption. Of course, this may be due to the need to adjust the carburetor, but this also happens. For example, if the ignition is set later, then the dynamics of the car will be low, and in order to accelerate normally, the engine needs more air-fuel mixture.
3. The appearance of shots in the silencer. If the explosion follows, it will take a certain time for the gases to expand. In the event that the piston reaches BDC, the next exhaust stroke will be, which means that a certain part of the fuel will be transferred to the exhaust system. Accordingly, pops will appear as a result.
4. The power unit began to work more noisily. and correctly put 2106 will be needed in case of shaking and tripping of the motor. The piston going up makes the work of the power unit more rigid, while the explosion of the mixture will occur towards it.

Installing and adjusting the distributor

On a VAZ 2106 car, distributor repair is necessary if it does not work correctly, but if this element is working properly, in order to set it correctly, you first need to set the marks. The crankshaft rotates either with a ratchet or with a special wrench for a nut. On the cover of the power unit you can see the marks.

To correctly set the ignition, the marks must be correctly aligned:

1. The first meta set in the direction of travel is ten degrees ahead of the angle. This parameter is relevant to use for cars using 72 fuel.
2. The mark located in the middle is an advance of the angle by five degrees, which is optimal for cars that are used on 80 gasoline.
3. The last risk is a lead angle of 0 degrees. This means that the ignition of the combustible mixture will be carried out at the time when the piston is located at TDC. When setting labels, you need to take into account these nuances.

When you are done setting marks, you need to put the desired gap in the contacts. To do this, the runner of the distribution unit must be removed and the fixing bolt of the interrupting element must be unscrewed. It is recommended to clean the contacts with sandpaper in advance. In the open state, the gap on the contacts should be no more than 0.4 mm.

Before, it is necessary to unscrew the fastening of the distribution unit with a wrench, then it can be removed from the housing.

In order for the unit to be put in place to work correctly, consider the following nuances:

1. The adjustment was made according to the TDC mark on the 1st cylinder, so at the moment the spark should appear in it. To catch this moment, you need to install the cover of the VAZ 2106 distributor and mark the place where the high-voltage spark plug cable from the first cylinder enters. Then it is necessary to dismantle the cover, after which the external contact of the slider is installed opposite the risks.
2. After that, in order for the power unit to work in normal mode, it is necessary to draw a conditional line between its clamps and put the mechanism in the installation site so that this line is parallel to the motor block. It should also be noted here that it is far from always possible to get into the slots right away, perhaps for this you need to scroll the case a little. In principle, this is not scary, since in the future the ignition will still need to be adjusted. You need to ensure that the mechanism can fully sit in the installation site, right up to the moment until it completely rests against the block. Having done this, the knot can be pulled into place (the author of the video is Andrey Gorinov).

Device malfunctions

Replacement and repair of the distributor on the domestic "six" is carried out in case of incorrect operation of the mechanism.

The following are the main symptoms of breakdowns that indicate possible malfunctions:

1. The vehicle jerks while driving. And these jerks are not typical for cars at all.
2. The motor generally does not start.
3. When you try to accelerate the car, the car can also twitch, and the acceleration process itself takes a lot of time, while the engine can detonate - the piston rings knock.
4. Increased fuel consumption.

As you can see, in general, the signs are similar to those that appear when the ignition is set incorrectly. Of course, if such symptoms appear, it is impossible to say for sure that the malfunction lies precisely in the distributor, however, attention should also be paid to the diagnosis of this node.

As for the breakdowns directly, which may force the car owner to repair or replace the mechanism, they are as follows:

1. Worn and burned out the slider of the node.
2. The problem lies in the cover itself - the contacts on it could burn out.
3. Hall sensor failure. The problem can be associated not only with a breakdown of the controller, but also with a bad contact on the controller plug.
4. Another reason that domestic drivers encounter quite often is the distributor bearing. He had a long operation, he could loosen up, but he could also just jam.
5. The presence of mechanical damage, including cracks on the cover.
6. Engine fluid enters the distribution unit, usually the problem is related to the tightness of the cover.

For the correct operation of the “six” motor, high-quality sparking is required, and for this an electronic gadget is used that contributes to its formation at the TDC of the piston group. This happens at a different time period for the operation of the “engine” for each cylinder. Such a device is called the VAZ 2106 distributor, and without its participation, the operation of an internal combustion engine is impossible.

The principle of operation and purpose of the distributor and some of its components

The correct operation of the ignition system (IS) is based on the ignition of the air-drop mixture at a certain time. For this, the necessary accumulation of electricity occurs with the help of a capacitor on the distributor, which is then transmitted to the SZ candles. On the electrodes of these elements, sparking occurs, leading to ignition and combustion of the airborne mixture, which serves for the subsequent operation of the vehicle's power plant.

An electronic device such as a distributor is designed to:

1. Initiation of the sparking process (depending on the type of breaker-distributor, if the contact type is due to the opening of the contact group, and in a non-contact distributor - due to the operation of the Hall sensor).
2. The directions of the high-voltage current created in the bobbin to the required SZ.
3. Changes in time at the moment of formation of a discharge spark under different modes of operation of the motor and the fuel used.
4. Providing with the help of a capacitor on the distributor the required charge and discharge of the current in the ignition coil.

Depending on the type of ignition, the price of a VAZ 2106 distributor can vary from 1,500 to 2,300 rubles, and products with electronic ignition are priced much more expensive. The car distributor consists of many elements, each of which performs its function. The distributor consists of several interconnected groups of electronic devices, which, ultimately, are responsible for the energy distribution system for the SZ candles. It is recommended that the distributor and runner be checked every time the vehicle's power system is tested.

The role of the capacitor on the distributor has already been determined, so let's consider the purpose of some other components of this electronic device. So, when the contacts of the VAZ distributor of the sixth model are opened, when the cylinder reaches the TDC in the SZ bobbin, a current with a high potential difference is accumulated, passing through the distributor slider, followed by transmission to the cover of the "six" distributor and then to the corresponding spark plug SZ.

It is always necessary to pay attention to the bearing of the distributor, because. its unsatisfactory condition, namely backlash and wear, significantly affect the quality of movement. In the event of defects in the distributor bearing, the vehicle will operate in an incorrect mode, twitch, and weakly gain power. Of great importance is the regular drive of the VAZ distributor, which is responsible for interacting with the power plant.

When operating the BSZ, a VAZ 2106 non-contact distributor is used, in which a transistor switching device is used and instead of a mechanical breaker, the latest generation cars are equipped with Hall sensors. Structurally, this detector is a simple element in its composition that induces magnetic waves. This is a plate on which, on one plane, there is a permanent type magnet, and on the other hand, the sensor itself. Between these components are slots of a special kind.

With the correct installation of the distributor on the VAZ 2106, when the shielding element isolates the magnetic field from the mounted magnet, this detector shows zero output voltage, and when special slots are opened, high-voltage current is supplied. The required order of pulse parameters is ultimately transmitted by the distributor to the car reel.

Distributor adjustment

Unscheduled adjustment of the "six" distributor is carried out in case of detection of the following defects in the course of the vehicle:

• unstable idling of the motor;
• power plant not to be started;
• stopping the movement of the propulsion unit.

The main cause of this group of malfunctions is the vehicle distributor. Of course, you can think about how to change the distributor and install a new product. However, the installation of the "six" distributor is premature, you can get by with a preliminary "spark" check, test the distributor slider and high-voltage wires of the electronic device.

The next stage is the contacts and cover of the VAZ 2106 distributor, which are checked for burning, and the contacts are also checked for the gap on the distributor, but this requires a special probe. Unscheduled repair of a distributor with BSZ is extremely rare due to its reliability. To install an electronic distributor, the following connection diagram is proposed:

The use of BSZ allows you to get rid of such a problem as setting the distributor on the VAZ 2106, which is extremely important for the correct operation of the outdated contact ignition system.

The distributor can be safely considered an outdated element of the sparking system, since it is absent on modern cars. The functions of the main ignition distributor (the technical name of the distributor) of gasoline engines are now performed by electronics. The specified part was massively used on passenger cars of past generations, including the VAZ 2106. The minus of switchgears is frequent breakdowns, a clear plus is ease of repair.

Purpose and types of distributors

The main distributor of the "six" is located on a horizontal platform made to the left of the engine valve cover. The shaft of the unit, ending with splines, enters the drive gear inside the cylinder block. The latter is rotated by the timing chain and simultaneously rotates the oil pump shaft.

The distributor performs 3 functions in the ignition system:

• at the right time, it breaks the electrical circuit of the primary winding of the coil, which causes a high voltage pulse to form in the secondary;
• alternately directs the discharges to the candles according to the order of operation of the cylinders (1-3-4-2);
• automatically adjusts the ignition timing when the crankshaft speed changes.

The spark is supplied and the air-fuel mixture is ignited before the piston reaches the upper extreme point, so that the fuel has time to fully burn out. At idle, the advance angle is 3-5 degrees, with an increase in the number of revolutions of the crankshaft, this figure should increase.

Various modifications of the "sixes" were completed with different types of distributors:

1. VAZ 2106 and 21061 were equipped with engines with a working volume of 1.6 and 1.5 liters, respectively. Due to the height of the block, distributors with a long shaft and a mechanical contact system were installed on the model.
2. VAZ 21063 cars were equipped with a 1.3 liter engine with a low cylinder block. The distributor is a contact type with a shortened shaft, the difference for models 2106 and 21063 is 7 mm.
3. The updated VAZ 21065 series was equipped with contactless distributors with a long stem, working in conjunction with an electronic ignition system.

The difference in the length of the drive shaft, depending on the height of the cylinder block, does not allow the use of the VAZ 2106 part on a 1.3 liter engine - the distributor simply will not sit in the socket. Putting a spare part with a short shaft on a “clean six” will also not work - the splined part will not reach the gear. The rest of the filling of contact distributors is the same.

As a young inexperienced driver, I personally encountered the problem of different lengths of ignition distributor rods. On my Zhiguli VAZ 21063, the distributor shaft broke off on the road. In the nearest auto shop I bought a spare part from the "six" and began to install it on a car. Result: the distributor was not fully inserted, there was a large gap between the platform and the flange. Later, the seller explained my mistake and kindly replaced the part with a 1.3 liter engine suitable for the engine.

Maintenance of a contact type distributor

In order to independently repair the distributor, it is necessary to understand its structure and the purpose of all parts. The algorithm of the mechanical distributor is as follows:

In fact, 2 electrical circuits pass through the distributor - low and high voltage. The first is periodically broken by a contact group, the second switches to the combustion chambers of different cylinders.

Now it’s worth considering the functions of the small parts that make up the distributor:

An important point should be noted: a manual octane corrector is found only on older versions of the R-125 distributors. Subsequently, the design changed - instead of a wheel, an automatic vacuum corrector with a membrane acting from engine vacuum appeared.

The chamber of the new octane corrector is connected by a tube to the carburetor, the rod is connected to the movable plate, where the breaker contacts are located. The magnitude of the vacuum and the amplitude of the membrane operation depends on the opening angle of the throttle valves, that is, on the current load on the power unit.

A little about the operation of a centrifugal regulator located on the upper horizontal platform. The mechanism consists of a central lever and two weights with springs. When the shaft spins up to high speeds, the weights under the action of centrifugal forces diverge to the sides and turn the lever. Breaking the circuit and the formation of a discharge begins earlier.

Typical malfunctions

Ignition distributor problems manifest themselves in one of two ways:

1. The engine is unstable - vibrates, "troits", periodically stalls. A sharp press on the gas pedal causes a pop in the carburetor and a deep dip, accelerating dynamics and engine power are lost.
2. The power unit does not start, although sometimes it “picks up”. Possible shots in the silencer or air filter.

In the second case, the fault is easier to detect. The list of reasons leading to a complete failure is relatively small:

• the capacitor or resistor located in the slider has become unusable;
• breakage of the wire of the low voltage circuit passing inside the housing;
• the cover of the distributor cracked, where the high-voltage wires from the candles are connected;
• the plastic slider failed - a rotor with a movable contact, screwed to the upper support platform and closing the centrifugal regulator;
• jammed and broke the main shaft.

A broken shaft leads to a complete failure of the VAZ 2106 engine. Moreover, a chip with splines remains inside the drive gear, as happened on my “six”. How to get out of the situation while on the road? I took off the distributor, prepared a piece of the "cold welding" mixture and stuck it to a long screwdriver. Then he lowered the end of the tool into the hole, pressed it against the fragment and waited for the chemical composition to harden. It remains only to carefully remove the screwdriver with a piece of the shaft stuck to the "cold welding".

There are many more reasons for unstable work, so it is more difficult to diagnose them:

• cover insulation breakdown, abrasion of its electrodes or central carbon contact;
• the working surfaces of the breaker contacts are badly burnt or clogged;
• the bearing is worn out and loosened, on which the base plate with the contact group rotates;
• the springs of the centrifugal mechanism have stretched;
• the diaphragm of the automatic octane corrector failed;
• water has entered the housing.

The resistor and capacitor are checked with a tester, the broken insulation of the cover and the slider is detected without any instruments. Burnt contacts are clearly visible to the naked eye, as are stretched weight springs. More diagnostic methods are described in the following sections of the publication.

Tools and preparation for disassembly

To independently repair the VAZ 2106 distributor, you need to prepare a simple set of tools:

• 2 flat screwdrivers with a narrow slot - regular and shortened;
• a set of small open end wrenches 5-13 mm in size;
• pliers, round-nose pliers;
• technical tweezers;
• probe 0.35 mm;
• hammer and thin metal tip;
• flat file, fine sandpaper;
• rag.

If you plan to completely disassemble the distributor, it is recommended to stock up on WD-40 spray lubricant. It will help displace excess moisture and facilitate the unwinding of small threaded connections.

During the repair process, additional devices and materials may be needed - a multimeter, a vise, pliers with pointed jaws, engine oil, and so on. You don’t have to create special conditions to carry out work; you can repair the distributor in an ordinary garage or in an open area.

So that during assembly there are no problems with setting the ignition, it is recommended to fix the position of the slider before removing the element according to the instructions:

To dismantle the distributor, you need to disconnect the vacuum tube from the membrane unit, disconnect the coil wire and unscrew the only fastening nut with a 13 mm wrench.

Lid and slider problems

The part is made of durable dielectric plastic, in the upper part there are outputs - 1 central and 4 side ones. Outside, high-voltage wires are connected to the sockets, from the inside, the terminals are in contact with a rotating slider. The central electrode is a spring-loaded carbon rod in contact with the brass pad of the rotor.

A high-potential pulse from the coil is fed to the central electrode, passes through the contact pad of the slider and the resistor, then goes to the desired cylinder through the side terminal and armored wire.

To identify problems with the cover, the distributor does not need to be removed:

Do not be afraid to mix up high voltage cables when disconnecting. Cylinder numbers are marked on top of the cover, which is easy to navigate.

An insulation breakdown between two contacts is diagnosed as follows:

Not knowing such subtleties, I turned to the nearest auto shop and bought a new cover with a return condition. I carefully swapped parts and started the engine. If the idling leveled off, left the spare part on the car, otherwise returned it to the seller.

Slider malfunctions are similar - abrasion of contact pads, cracks and breakdown of insulating material. In addition, a resistor is installed between the contacts of the rotor, which often fails. If the element burns out, the high-voltage circuit breaks, the spark is not supplied to the candles. If black marks are found on the surface of the part, its diagnostics are necessary.

Important note: when the slider becomes unusable, there is no spark on all candles. Insulation breakdown is diagnosed using a high-voltage cable coming from the coil. Pull the end of the wire out of the cover, bring it to the central contact pad of the slider and turn the crankshaft with a starter. A discharge appeared - it means that the insulation is broken.

Checking the resistor is simple - measure the resistance between the terminals with a multimeter. An indicator from 5 to 6 kOhm is considered normal, if the value is greater or less, replace the resistance.

Video: how to check the functionality of the slider

Contact group troubleshooting

Since a spark jumps between the contact surfaces when opening, the working planes gradually wear out. As a rule, a ledge is formed on the movable terminal, and a recess is formed on the static terminal. As a result, the surfaces do not fit well, the spark discharge weakens, the motor begins to “troit”.

A detail with a small output is restored by stripping:

1. Remove the distributor cover without disconnecting the cables.
2. Using a screwdriver, push the contacts apart and slide a flat file between them. The task is to remove the build-up of the movable terminal and align the static terminal as much as possible.
3. After stripping with a file and fine sandpaper, wipe the group with a rag or blow it with a compressor.

In stores, you can find spare parts with upgraded contacts - holes are made in the center of the working surfaces. They do not form depressions and growths.

If the terminals are worn to the limit, it is better to change the group. Sometimes the surfaces are deformed to such an extent that it is impossible to adjust the gap - the probe is inserted between the bump and the recess, too much clearance remains at the edges.

The operation is performed directly on the car, without dismantling the distributor itself:

Installation of contacts is not difficult - screw the new group with screws and connect the wire. Next is the gap adjustment of 0.3-0.4 mm, performed using a feeler gauge. It is necessary to turn the starter a little so that the cam presses on the plate, then adjust the gap and fix the element with the adjusting screw.

If the work planes burn too quickly, it is worth checking the capacitor. Perhaps it is dry and does not perform its function well. The second option is the low quality of the product, where the opening surfaces are offset or made of ordinary metal.

Bearing replacement

In distributors, a roller bearing is used for the correct operation of the octane corrector. The element is aligned with the horizontal platform where the contact group is attached. To the protrusion of this platform is attached a rod coming from a vacuum membrane. When the vacuum from the carburetor begins to move the diaphragm, the rod turns the pad along with the contacts, correcting the moment of sparking.

During operation, play occurs on the bearing, which increases with wear. The platform, together with the contact group, begins to dangle, opening occurs spontaneously, and with a small gap. As a result, the VAZ 2106 engine is very unstable in any mode, power is lost, and gasoline consumption increases. The bearing is not repaired, only changed.

The backlash of the bearing assembly is determined visually. It is enough to open the distributor cover and shake the contact breaker up and down by hand.

Replacement is performed in this order:

1. Remove the distributor from the car by disconnecting the coil wire and unscrewing the fastening nut with a 13 mm wrench. Do not forget to prepare for dismantling - turn the slider and make chalk marks, as described above.
2. Dismantle the contact group by unscrewing 3 screws - two fixing screws, the third holds the terminal.
3. Using a hammer and a thin tip, knock out the stopper rod from the oil slinger. Remove the latter from the shaft without losing the second washer.
4. Remove the shaft along with the slider from the housing.
5. Disconnect the octane corrector rod from the moving platform and unscrew the membrane unit.
6. Prying the plate on both sides with screwdrivers, pull out the worn bearing.

Installation of a new element is carried out in the reverse order. Before installing the inside of the distributor, it is advisable to thoroughly clean it. If rust has formed on the roller, remove it with sandpaper and lubricate the clean surface with engine oil. When you insert the shaft into the housing sleeve, do not forget to adjust the contacts on the feeler gauge.

When installing the distributor, keep the original position of the body and slider. Start the engine, loosen the element fixing nut, and rotate the body to achieve the most stable operation. Tighten the mount and check the "six" on the go.

Other malfunctions

When the engine categorically refuses to start, you should check the performance of the capacitor. The technique is simple: seat an assistant behind the wheel, remove the distributor cap and give the command to rotate the starter. If a barely noticeable spark jumps between the contacts, or one is not observed at all, feel free to buy and install a new capacitor - the old one can no longer provide the required discharge energy.

Any experienced driver operating the "six" with a mechanical distributor carries a spare capacitor and contacts. These spare parts cost a penny, but without them the car will not go. I was convinced of this from personal experience, when I had to look for a capacitor in an open field - a passing Zhiguli driver helped, who gave me his own spare part.

The owners of the VAZ 2106 with a contact distributor are also annoyed by other minor troubles:

1. The springs holding the weights of the centrifugal corrector are stretched. There are small dips and jerks at the time of acceleration of the car.
2. Similar symptoms are observed in the case of critical wear of the vacuum diaphragm.
3. Sometimes the car stalls for no apparent reason, as if the main ignition wire was pulled out, and then it starts and runs normally. The problem lies in the internal wiring, which has broken and periodically breaks the power circuit.

It is not necessary to change stretched springs. Unscrew the 2 screws securing the slider and, using pliers, bend the brackets where the springs are fixed. A torn membrane cannot be repaired - you need to remove the assembly and install a new one. Diagnosis is simple: disconnect the vacuum tube from the carburetor and draw air through it with your mouth. A working diaphragm will begin to rotate the plate with contacts by means of a thrust.

Device and repair of contactless distributor

The device of the distributor, acting in conjunction with the system, is identical to the design of a mechanical distributor. There is also a plate with a bearing, a slider, a centrifugal regulator and a vacuum corrector. Only instead of the contact group and the capacitor, a magnetic Hall sensor is installed plus a metal screen mounted on the shaft.

How does a contactless distributor work:

1. The Hall sensor and the permanent magnet are located on a movable platform, a screen with slots rotates between them.
2. When the screen covers the magnet field, the sensor is inactive, the voltage at the terminals is zero.
3. As the roller rotates and passes through the slit, the magnetic field reaches the sensor surface. A voltage appears at the output of the element, which is transmitted to the electronic unit - the switch. The latter gives a signal to the coil that produces a discharge that enters the distributor slider.

The VAZ 2106 electronic system uses a different type of coil that can work in conjunction with a switch. It is also impossible to convert a conventional distributor to a contact one - it will not be possible to install a rotating screen.

The non-contact distributor is more reliable in operation - the Hall sensor and the bearing become unusable much less often due to the lack of mechanical load. A sign of a meter failure is the absence of a spark and a complete failure of the ignition system. Replacement is easy - you need to disassemble the distributor, unscrew 2 screws securing the sensor and pull the connector out of the groove.

Malfunctions of other elements of the distributor are similar to the old contact version. Troubleshooting methods are detailed in previous sections.

About the drive mechanism

To transmit torque to the distributor shaft on the "six", a helical gear is used, rotated by the timing chain (colloquially - "boar"). Since the element is located horizontally, and the distributor roller is vertical, there is an intermediary between them - the so-called fungus with oblique teeth and internal slots. This gear simultaneously turns 2 shafts - the oil pump and the distributor.

Find out more about the timing chain drive device:

Both transmission links - "boar" and "fungus" are designed for a long service life and are changed during the overhaul of the engine. The first part is removed after disassembling the timing chain drive, the second is pulled out through the upper hole in the cylinder block.

The VAZ 2106 distributor, equipped with a contact breaker, is a rather complex unit, consisting of many small parts. Hence the unreliability in operation and the constant failures of the sparking system. The non-contact version of the distributor creates problems much less often, but in terms of performance it still falls short of modern ignition modules, which have no moving parts.
