Replacing the distributor on a VAZ 2107 with your own hands Photo instructions on how to change the distributor on a VAZ 2107

A distributor is a device responsible for producing a spark at the right moment. The part is installed on internal combustion engines. When the piston is at the top point, ignition occurs.

A distributor is a breaker-distributor. Without it, not a single gasoline internal combustion engine can operate. You can find this device on cars such as:

Without a distributor, the timely formation of a spark in the engine cylinders would be impossible.

PURPOSE OF THE DEVICE

One of the most important subsystems of a gasoline engine is the ignition system. The fact is that normal operation of the engine is possible only if the combustion of the fuel-air mixture occurs in a timely manner. Otherwise, the entire work algorithm is disrupted.

During operation of the device, voltage is generated. It is served on candles. It is on them that the spark necessary to ignite the mixture is formed. As a result, the engine starts working and the car moves in the right direction.

For all the processes described above to become a reality, a distributor is needed. In this system it performs the following functions:

1. Acts as an initiator of spark formation. This occurs due to the opening of contacts.
2. The device directs the generated voltage to the desired spark plug.
3. The distributor can, if necessary, change the moment of sparking. This parameter is determined by the driving mode selected by the driver. Also, a lot depends on the quality and type of fuel.
4. The device is capable of storing energy in a bobbin.

As you can see, the part performs many functions. It is not surprising that without its normal operation, the operation of the engine is impossible.

The problem with the "spark"

A fairly common malfunction, especially among car owners of old domestic cars, is associated with loss of spark. It causes a lot of problems for car owners.

As was written above, initially doubts when the spark disappears fall on the contacts of the distributor. But there are other reasons for this. In general, you need to be able to immediately determine if the spark has disappeared, whether this has happened before or this is the first time.

Why is there no spark

So, there may be several options for the spark to disappear. And all of them are connected, whatever one may say, with electrical equipment. The ignition system does not provide full efficiency, and as a result, the power of the internal combustion engine is lost.

More symptoms: the engine jerks while driving (2-4 thousand rpm), it starts hard, popping noises are heard in the exhaust system, the former throttle response has disappeared.

Distributor design

The distributor circuit assumes the presence of such elements as:

• low voltage current breaker;
• high voltage current distributor;
• centrifugal ignition timing regulator;
• vacuum ignition timing regulator.

The distributor circuit is designed so that at a certain moment the breaker opens the primary ignition circuit, as a result of which a high voltage current is created in the secondary winding of the ignition coil. Through the distributor, this current is transmitted to the spark plugs in certain cylinders. The regulators automatically adjust the ignition timing, which depends on the current operating mode of the engine.

The distributor breaker is an electromechanical part and consists of the following parts:

• shaft;
• movable contact plate;
• movable contact plate;
• capacitor;
• frame.

The breaker shaft consists of two main parts. On one of them, depending on the type of breaker, cams are installed, the number equal to the number of cylinders in the engine. This distributor device is not very reliable, since a large number of contacts, as well as the presence of moving parts, lead to regular problems with this unit.

The distributor device, as well as its use in general, are outdated from the point of view of modern electrical equipment, but in our country there are still a lot of carburetor engines, so the problem of the performance of this unit is currently relevant.

As for where the distributor is located in the car, most often it can be found under the hood next to the engine, near the cylinder head or on it. Although the exact location of the node depends solely on the model of the machine.

Replacing the VAZ 2106 distributor with your own handsAutoRemka

Distributor malfunctions lead to malfunctions in the ignition system. You can guess that the distributor is faulty by such characteristic signs as sudden jerks of the car while driving and discordant operation of the engine at idle.

The essence of such a procedure as repairing or replacing a VAZ 2106 distributor is to replace the worn parts included in it.

To carry out repair work you will need:

2 7 mm wrenches, 10 and 13 mm wrenches, two screwdrivers, a hammer, a set of flat feeler gauges, mandrels for knocking out and pressing in distributor bushings (bearings), and tweezers.

When all the tools are prepared, you can start working.

1. We unscrew the 2 fastening screws that secure the connection of the distributor rotor with the support plate of the ignition timing regulator, after which we remove the rotor itself.

2. The springs and weights of the centrifugal ignition timing regulator must be marked so as not to get confused during assembly and put everything in its original place.

3. Next, use a screwdriver to remove the springs of the centrifugal regulator (a screwdriver is needed to pry off the springs).

4. While holding the nut on the moving contact screw, unscrew the nut that secures the wire ends (the capacitor wire and the wire coming from the ignition coil).

5. Now you need to unscrew the screw that secures the distributor housing to the capacitor housing, then remove it.

6. Next, unscrew the screw that secures the tip of the movable contact wire (the nut must be held in place) and remove the insulating spacer, as well as the washers (spring and 2 flat washers - insulating and metal).

7. The next step is to unscrew the two screws that connect the contact group to the movable distributor plate.

8. After unscrewing the fastening screws, remove the contact group, followed by the insulating washers located on the axis of the contact group (flat and locking).

9. Next, use a flat screwdriver to pry off the washer that insulates the spring plate of the movable contact, and remove the movable contact itself from the axis of the contact group.

10. From the axis of the movable plate of the distributor, remove the lock washer located on the fastening of the vacuum regulator rod.

11. Use a screwdriver to pry up the vacuum regulator rod and remove it from the axis of the distributor plate.

12. Unscrew the two screws that secure the vacuum regulator housing to the distributor body and remove the regulator.

14. Press out the pin that secures the low-reflection coupling from the distributor shaft, then remove the coupling, followed by the washer.

15. Remove the distributor shaft from the housing.

17. Unscrew the 2 screws that secure the bearing locking plates, remove the spring washers and remove the plates using tweezers.

18. Next, remove the movable plate assembled with the bearing from the distributor body.

19. Check the condition of the distributor shaft - there should be no visible signs of wear on the surface of its contact with the bearing.

20. We check the capacitor using for this procedure a device that measures capacitance (normal values ​​are in the range of 0.20-0.25 μF).

21. Then you should check the condition of the diaphragm of the vacuum ignition timing regulator (to do this, you need to press the rod and plug the fitting... the rod must be held by the diaphragm).

22. We inspect the contacts of the breaker - there should be no dirt, erosion or signs of burning on them. If the above-mentioned contaminants are present, the contacts should be cleaned using a velvet file (under no circumstances should sandpaper be used for this purpose) and washed with alcohol or gasoline.

23. The distributor housing bushing with signs of wear should be replaced with a new one. Pressing out and pressing of the bearing should be done using a mandrel of the appropriate diameter.

24. The distributor should be assembled in the opposite order to the disassembly order, taking into account the following features.

Upon completion of assembly, the distance between the breaker contacts should be adjusted. The gap should be from 0.35 to 0.45 mm.

The fold located on the movable plate of the distributor must be lubricated with engine oil (literally 2-3 drops of oil will be required). The same should be done with the bearing, adding a couple of drops of oil through the oiler, which is installed on the distributor body, and the splined part of the distributor shaft.

Operating principle of the distributor

In many ways, the operating principle of the distributor remained unchanged for many years. In VAZ cars, such as VAZ 2109, 2106, 2107, 2108, an ignition system of this type was used almost until the end of the last century.

The basis of the work is the connection of the distributor with the engine crankshaft. When the piston in the first cylinder takes the position corresponding to TDC, the breaker contacts open, a high voltage appears in the ignition coil, directed through a slider located in the distributor cover to the spark plug of the first cylinder.

There the combustion of the fuel assembly occurs, and the crankshaft continues to rotate. In addition to moving the pistons, it causes the breaker cam to rotate. When in another cylinder another piston occupies a position corresponding to TDC, at this moment the breaker contacts in the distributor open again, and a high-voltage voltage is generated in the ignition coil and supplied to the desired spark plug.

This joint rotation of the crankshaft, the breaker cam and the distributor slider ensures that a spark appears where and when needed. However, this does not cover all aspects of how the distributor works. To understand its operation, it is necessary to touch upon such concepts as the angle of the closed state of contacts (UZSK) and the ignition timing angle (IAF)

UZSK

A concept such as UZSK characterizes the time when the breaker contacts are closed. In essence, this is an indirect characteristic of the accumulation of energy in the coil after the completion of spark formation. UZSK directly affects the amount of energy spent on sparking and, accordingly, on engine operation.

In cases where the distance between the contacts is small, the coil will not accumulate the necessary energy and the spark energy will be low, which will lead to interruptions in the operation of the motor. A large gap also leads to interruptions, since the contact breaking time is reduced and the coil does not have time to fully discharge.

Each ignition system has its own optimal UZSK, to ensure which, if necessary, the distributor must be checked and adjusted.

UOZ

This concept concerns the moment of ignition of a fuel assembly. The fact is that its combustion does not occur instantly, and often, to ensure optimal conditions for such a process, it must begin earlier than the piston reaches the TDC position. The OZ characterizes the time by which the appearance of a spark precedes the appearance of the piston in the TDC position.

How to evaluate the work already done

Accurate diagnosis is carried out using a computer. However, it is also possible to independently assess how correctly the circuits are functioning.

1. With the ignition off, check the contacts.
2. Find out the voltage inside the module at terminals C and B.
3. Check the high voltage wire. To do this, you need to take a candle and place it in the cap. In this case, it should be attached to the cylinder block. If the internal combustion engine is turned on using the starter, a spark will appear. The check is done for all wires. If a spark does not appear, then you need to check or even replace the entire ignition system.
4. If the engine continues to operate incorrectly, the power system will need to be checked.

For the carburetor model VAZ 2110, marks are also set in order to regulate the ignition system.

If the ignition of the VAZ 2110 8-valve injector occurs early or, conversely, late, then the ergonomics of the entire engine deteriorates. Power also decreases. The engine is exposed to high temperatures and excessive loads. Among other things, detonation may occur. All this can lead to the VAZ 2110 losing ignition.

DETAILS ABOUT THE MOST IMPORTANT ELEMENTS OF THE TRAMBER DEVICE

VACUUM REGULATOR

It is this device that can change the OZ if necessary. As soon as the motor load changes, appropriate adjustments are made to the operation of the distributor device parts.

The vacuum regulator of the distributor is a closed cavity. To ensure better performance, the design is divided by a diaphragm. One cavity goes directly to the carburetor.

When a vacuum occurs, the diaphragm begins to move. As a result, pressure is exerted on the movable disk and the breaker cam. The response time of the latter is adjusted depending on the current situation.

OCTANE-CORRECTOR

This is a very important element in the distributor design. Without it, the entire system could not function normally. The unit changes the SOP depending on the fuel that is currently being used.

By its design, this distributor element resembles two plates with an arrow. The same arrow is installed on the engine. There are special lines on it, through which the ignition angle is adjusted. It is almost impossible to do without this part when refueling different types of gasoline.

Distributor malfunctions

The following signs indicate that the distributor is malfunctioning:

When there is a spark on the central wire, but not on the spark plug wires, this indicates a breakdown of the slider.

1. the car jerks periodically when driving;
2. Unstable engine operation at idle;
3. the engine does not start at all;
4. the knocking of the piston fingers is heard while accelerating;
5. the speed increase dynamics decreased;
6. fuel consumption has increased.

In most cases, the causes of distributor failure are:

Breakdown of the roof and ignition coil occurs due to large gaps in the contacts of the distributor cover and slider, spark plugs and bad candlesticks.

1. burnout of the runner;
2. oxidation or shorting of contacts under the cover;
3. breakdown of the distributor cover;
4. failure of one of the sensors;
5. problems with the shaft bearing and other problems.

In each of these cases, replacement is required. But at the same time, for almost any car, it is possible to change not the entire distributor, but only its failed part, which is an advantage, since it significantly reduces the cost of repairs.

The most basic check of the distributor is a visual assessment of the condition of the slider, contacts and cover.

In a contactless distributor, the main malfunction is the failure of the hall sensor or inductive sensor.

To check the ignition system and distributor, among other things, observe the spark on the unscrewed spark plug after starting the engine. In garage conditions, you can also check using measuring instruments or indicators.

The distributor capacitor is also one of the parts that often fail. It helps to increase the voltage supplied to the spark plugs when the engine starts. And in order to check it, you need to disconnect it and touch the “ground”, and if a characteristic crackling sound is heard and a voltage drop is observed, the capacitor is working, if this does not happen to the replacement part.

A distributor is always a dismountable unit that can be disconnected, removed from the car, disassembled into components, a problem can be detected and eliminated by replacing the damaged part.

The design and principle of operation of a distributor breaker or distributor - video

Some owners of classic cars of the VAZ 2101-07 family are constantly trying to improve, modify, add electronics and convenience. One of these improvements is the installation of contactless electronic ignition.

Checking the coil

In the process of checking the performance of the coil, the first thing to do is check the voltage supply to it.
For this purpose, the voltage supply is turned on and then it is measured between terminal B+ and ground. This value is 12 V. If voltage is not supplied to the coil, then the reason for its absence should be sought in the lock. If normal voltage is present and there is no spark on the spark plugs, it is necessary to measure the resistance of the windings. To do this, the contacts of the measuring device are applied to two side terminals. For the primary winding, the resistance value should be 3-4 ohms.

The resistance of the secondary winding is within 7-9 Ohms. The coil cannot be checked for the presence of a spark by leaning the high-voltage wire against the motor body, since in this case the gap becomes so large that the increased resistance causes breakdown of the winding of the unit, and this leads to failure.

Which ignition is better: contactless or contact?

Contact ignitions are obsolete, but are still used in older cars. On rear-wheel drive VAZ models, contactless was first installed on 2107.

Let's look at the differences between contact and non-contact ignition:

Advantages of contactless ignition:

• since there is no contact group in the distributor, sparking occurs clearly;
• long coil life;
• at medium engine speeds, BSZ creates a spark 4 times more powerful than contact ignition. This is especially useful if the spark plugs are dirty, as a spark will still be produced;
• performs its functions perfectly even in cold weather;
• if the voltage in the electrical network is low, then sparking will still occur;
• thanks to the powerful, stable spark of the candles, the fuel-air mixture ignites faster;
• if BSZ is installed, then fuel consumption decreases and engine power increases;
• improved vehicle acceleration dynamics;
• BSZ is easier to maintain because the device has no moving parts.

Non-contact ignition system device

The BSZ device for carburetor engines consists of:

1. Distributor. This is a device that is responsible for creating a spark at the right moment. It is also called the ignition system distributor.
2. High voltage coil. This element in the ignition system receives low voltage from the battery, converts it and supplies high voltage. Therefore, high-voltage wires come from it. The coil consists of two windings. The primary one is made of a large cross-section wire (connected to the electrical part of the car via the ignition switch relay), the secondary one is made of many turns of thin wire (connected with a high-voltage wire to the distributor).
3. Switch. This element of the contactless ignition system is responsible for the formation of a spark. In simple words, a switch is a signal amplifier. The switch is only available in the ignition system of internal combustion engines with a carburetor. By the way, SOLEKS is considered the best carburetor. On injection VAZ 2107, as well as on others, a switch is not needed, since its functions are performed by the on-board computer controller.
4. High voltage and normal wiring. High voltage wiring must meet heavy insulation requirements.
5. Terminals. Serve for connections and must be strong.

Electronic and contactless ignition systems are the same device. It got its name due to the absence of a contact group in the system design. The ignition switch also has a contact group, which is a common cause of engine failure.

About the drive mechanism

To transmit torque to the distributor shaft on the “six”, a helical gear is used, rotated by a timing chain (in common parlance – “pig”). Since the element is located horizontally and the distributor roller is vertical, there is an intermediate element between them - the so-called mushroom with oblique teeth and internal grooves. This gear simultaneously drives 2 shafts: the oil pump and the distributor.

More information about the design of the timing chain drive: https://bumper.guru/klassicheskie-modeli-vaz/grm/kak-vystavit-metki-grm-na-vaz-2106.html

The distributor transmission consists of two helical gears

Both transmission links - the “hog” and the “fungus” - are designed for a long service life and are modified during engine overhauls. 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 switch, is a rather complex unit consisting of many small parts. Hence the unreliability of operation and constant failures of the ignition system. The non-contact version of the distributor creates problems much less often, but its characteristics are still inferior to modern ignition modules, which have no moving parts.

Electronic ignition connection diagrams: VAZ 2101-VAZ 2107

Scheme of a contactless ignition system for VAZ cars:

1 - switch; 2 — ignition coil (bobbin); 3 — distributor; 4 — ignition key; 5 - Hall sensor.

How contactless ignition works

The sequence and principle of operation of the BSZ is as follows:

1. The driver turns the ignition key.
2. The circuit is closed and constant voltage from the battery is supplied to the primary winding of the ignition coil. The energized primary winding forms a magnetic field around itself.
3. When the starter starts, it begins to rotate the crankshaft of the internal combustion engine and rotates the shaft, which is located inside the distributor along with the slider.
4. The hall sensor detects how the distributor shaft rotates (along the protrusion on the shaft) and transmits a signal to the switch.
5. The electronic unit turns off the voltage supply to the primary winding based on the signal from the Hall sensor.
6. When the voltage supply circuit is interrupted, at that moment a high voltage pulse of up to 24 kilovolts appears in the secondary winding of the coil, which is transmitted through a thick wire to the slider (the moving part of the distributor).
7. Fixed contacts are built into the roof. The runner throws an impulse onto one of these stationary contacts. From the contact that received the high voltage pulse, it is transmitted through high-voltage wires to the spark plugs of those cylinders in which the pistons are at top dead centers.
8. When voltage is applied to the spark plug, the working combustion chamber of the cylinder already contains fuel and air in a compressed state for ignition.
9. The distributor slider rotates to spark all spark plugs according to a certain sequence pattern: 1-3-4-2. Depending on how to install the slider, the entire operation of the system depends, early ignition or later, we learned to determine in another material.
10. The car engine starts.

ECMs are sometimes interchangeable, but sometimes they are not repairable.

Diagram of an outdated VAZ ignition system (without switch)

This scheme is in systems where there is no switch. The circuit is broken mechanically using a breaker.

Disadvantages of contact ignition:

1. The contacts burn and oxidize, which reduces the power to create a spark.
2. There are wear parts that are recommended to be changed every 20 thousand km. mileage
3. Converted power in contact systems is up to 18 kilovolts. For electronic or contactless ones - up to 24 kilovolts.

Disadvantages of contactless ignition:

• The Hall sensor cannot be repaired. Working service life up to 50 thousand km. mileage

Contact distributor

All models and modifications of Zhiguli were equipped with contact type distributors until the early 90s of the last century. A distributor with serial number 30.3706 was installed on the VAZ 2107.

A contact distributor is no different in appearance from a contactless one.

Design of contact breaker-ignition distributor 30.3706

The contact distributor consists of the following elements:

• frame;
• rotor (shaft);
• slider (rotating contact);
• contact breaker;
• capacitor;
• centrifugal and vacuum ignition timing regulators;
• cover with main (central) and four side contacts.

  
  The difference in the design of contact and non-contact distributors lies only in the device that generates the impulse

Housing and shaft

The base of the device is cast from aluminum. A cermet bushing is pressed into its upper part, playing the role of a support bearing for the distributor shaft. The side of the housing is equipped with an oiler through which the bushing is lubricated in order to reduce the friction force. The lower part of the shaft (shank) has splines for connecting additional engine elements to the drive gear. With their help it is set in motion.

The shaft of the device is driven by the drive gear of additional engine units

Runner

A slider is installed at the top of the rotor. It is made of plastic and has two contacts connected through a resistor. Their task is to receive voltage from the coil through the central electrode and transfer it to the side contacts of the distributor cap. The resistor is used to eliminate radio interference.

The slider has two contacts connected to each other through a resistor

chopper and capacitor

The breaker mechanism includes a group of contacts and a cam with four protrusions. The contacts are fixed on a movable plate, the rotation of which is ensured by a ball bearing. To be able to adjust the gap between the contacts, one of the mounting holes is made in the form of an oval. The moving contact is located on a spring-loaded lever. The other contact is stationary. In a calm position they are closed.

The cam is the thickened part of the shaft. Its protrusions serve to actuate the moving contact. When the breaker-distributor shaft begins to rotate, the cam with one of its protrusions rests against the movable contact block, moving it to the side. Then the protrusion passes the block and the contact returns to its place. This is the simple way to close and open the low voltage circuit in the contact ignition system.

The pulse is formed by opening the breaker contacts

Despite the fact that the voltage on the contacts is small, when they open, a spark is still formed. In order to eliminate this phenomenon, a capacitor is installed in the breaker circuit. It is attached with a screw to the distributor body.

The capacitor prevents the formation of a spark at the contacts during their opening

Centrifugal regulator

The primary adjustment of the moment of spark formation in VAZ 2107 cars is carried out by turning the entire distributor . Further adjustments are made automatically. The function of the centrifugal regulator is to change the ignition timing depending on the number of engine crankshaft revolutions.

The basis of the mechanism design is the support and drive plates. The first is soldered to a bushing that is movably fixed on the distributor shaft. It can rotate relative to the shaft with an amplitude of 15°. On top it has two axles on which weights are installed. The drive plate is mounted on the upper end of the shaft. The plates are connected to each other by two springs of different stiffness.

The centrifugal regulator adjusts the ignition angle depending on the crankshaft speed

When engine speed increases, centrifugal force also increases. It first overcomes the resistance of a softer spring, then a stiffer one. The weights rotate on their axes and rest against the support plate with their side protrusions, causing it to rotate together with the slider to the right, thus increasing the ignition timing.

Rotation of the support plate is ensured by centrifugal force

Vacuum regulator

The vacuum regulator is attached to the distributor body. Its role is to adjust the ignition angle depending on the load on the power plant. The design of the device consists of a reservoir, a membrane with a rod located in it, as well as a hose through which the regulator is connected to the primary chamber of the carburetor.

The vacuum regulator adjusts the ignition angle depending on the engine load

When a vacuum appears in the carburetor, it is transmitted through a hose to the reservoir of our device. A vacuum is created there. When this happens, the membrane moves the rod, and it acts on the rotating breaker plate, turning it counterclockwise, increasing the ignition timing.

The chopper plate rotates under the influence of vacuum created in the carburetor

Contact type distributor malfunctions and their symptoms

Taking into account the fact that the distributor is a rather complex device, it is subject to the influence of a number of negative factors that can damage the elements of its design. That is why the distributor can have a lot of malfunctions. Well, as for common device breakdowns, they include:

• electrical breakdown of the lid;
• wear of the central electrode or side contacts of the cover;
• burning of the slider contacts;
• electrical breakdown of the capacitor;
• violation of the gap between the contacts of the breaker;
• wear of the moving plate bearing.

  
  If the contacts are severely worn, the cover must be replaced

Each of the listed malfunctions has its own symptoms, but in most cases they are of the same nature. If the distributor cover is punctured, its contacts or the slider contacts are worn out or burned, engine performance will deteriorate. The same thing will happen if the gap between the contacts of the breaker is broken, they become dirty or burnt. In this case, the following are most often observed:

• vibration;
• overheat;
• misfires;
• change in exhaust color;
• rare “lumbago” in the gas exhaust system;
• increase in gasoline consumption.

  
  You can replace a faulty slider yourself

Failure of the moving plate bearing may be accompanied by a characteristic whistle or squeal coming from under the cover.

Selection of BSZ

When purchasing a new BSZ, you should pay attention to the presence of the components of the entire kit. The factory kit should contain:

1. Distributor (main distributor). The code for engines 1.5 and 1.6 is 38.37061. For 1.3 engines, the number will be 38.3706–01, because the height of the 1.3 engine block is lower and the distributor shaft is shorter.
2. Switch number 36.3734 or 3620.3734.
3. High voltage coil (reel). Marking 27.3705
4. Thin wires with connectors.

In appearance, the BSZ kit for the VAZ 2121 NIVA is very similar. But it’s better not to install this kit on a VAZ 2107 or a VAZ 2106, because the characteristics of the “six” and “seven” are very different from the “Niva”. Distributor brands for Niva: 3810.3706 or 38.3706–10.

The best manufacturer of electronic ignition systems for old VAZ cars is. The production capacity base is located in the city of Stary Oskol. According to reviews from car owners of classic BSZ SOATE models, this is an excellent option.

A classic and original way to strip contacts

Here's what you need to do with the standard, classic version of stripping:

• The terminal from the battery is removed.
• The chips and armored wires going to the distributor are removed.

Attention. It is recommended to write down the wires by numbers so that when you put them in place after the operation is completed, you do not get confused.

• Remove the distributor cover using a 5.5 socket.
• Visually inspect the slider, which should not interfere with work.

Advice. If the slider interferes with stripping, it is recommended to put the car in 5th gear and push it forward a little. The runner will then stand up as needed.

• The slider and contacts are thoroughly cleaned first with large HDD paper, and then with fine paper.

Note. You must act slowly, without pressing hard.

• The wires are put in place.

Replacing the distributor contact system

Stable current is the goal of this repair. You can cope with such cleaning of contacts in just fifteen minutes.

An original way to strip contacts without removing VSKV wires.

• The lower screw is removed (if it does not lend itself, process the VD).
• The inside of the cover provides access to the contacts.

Note. White deposits on the contacts once again prove the need for cleaning.

• The plaque is carefully removed with a knife.
• The contacts are treated with fine sandpaper.

The effect should make itself felt immediately after starting the internal combustion engine. The car will become faster already in the first meters of driving.

Installation of contactless ignition for VAZ 2107, 2106

To install the BSZ with your own hands, you will need the following tools:

• Screwdrivers (flat and Phillips);
• Open-end wrenches 8, 10, 13 mm;
• Pliers (pliers);
• Candle key;
• Drill or screwdriver with a drill diameter of 3-3.5 mm. You will have to drill two holes in the body to secure the switch.
• A special wrench for rotating the crankshaft of an internal combustion engine or a regular open-end wrench of 30 mm.

An inspection hole for installing the ignition is not required. Here, in fact, is the procedure for removing the old contact ignition:

1. Open the hood, disconnect the battery and disconnect the high-voltage wires from the spark plugs.
2. Unscrew the spark plugs.
3. Rotate the engine crankshaft until the piston in the first cylinder reaches top dead center (TDC). You can use a long screwdriver or wire to check where the piston is located. Make sure that the mark on the engine crankshaft pulley coincides with the very first long mark on the cylinder block.
4. Disconnect the latches of the distributor cover and remove it with the wires. Draw a mark on the valve cover opposite the slider.
5. Disconnect the hose coming from the carburetor and all distributor wires.
6. Unscrew the fastening nut and remove the distributor along with the gasket.
7. Unscrew the coil mounts (remember which wires are attached where) and remove it.

The procedure for installing contactless electronic ignition on a VAZ 2106-2107.

1. Drill and attach the commutator next to the coil. But, do not place it under tanks with liquid.
2. Remove the cover of the new distributor and put on the gasket.
3. Install into the seat for the distributor so that the moving contact is opposite the drawn mark on the valve cover. Do not immediately tighten the nut all the way.
4. Install the new coil where the old one was. The wires from the ignition switch relay, tachometer, and switch must be connected to the reel terminals. The wire from the electronic unit number 1 is connected to the coil terminal marked “K”, the wire from the 4th contact is connected to the coil terminal marked “B”.
5. Check the gaps of the spark plugs (should be 0.8-0.9 mm) and screw them in place.
6. Snap the distributor cover and connect the high-voltage wires (the central one from the coil and 4 wires to the spark plugs). We connect the wires to the spark plugs strictly in accordance with the designations.
7. Connect the vacuum hose.

After installation in the correct sequence, we start the engine and begin setting up the ignition. If after installing a new electronic contactless ignition the engine does not start, you should check the correct connection of the coil wires and the high-voltage wires to the spark plugs. If the wires are normal, then the marks are not aligned.

Checking and adjusting the marks on the eight-valve injection valve

To adjust the ignition you will need the following tools:

• jack;
• wheel wrench;
• key (head) 10;
• key to 13;
• key to 17;
• key to 19;
• large slotted screwdriver;
• flashlight.

It is also advisable to involve an assistant.

Work order:

1. We install the car on a horizontally flat surface. We block the rear wheels.
2. Using a wheel wrench, unscrew the bolts securing the right wheel and jack it up. Unscrew the bolts completely and remove the wheel.
3. Open the hood, use a 10 mm socket to unscrew the three bolts securing the front protective cover of the timing drive. Let's take it off.
4. Using a 13mm wrench, loosen the generator belt tensioner nut and remove the belt.
5. Using a 19mm wrench, unscrew the nut securing the generator pulley. To do this, you will need an assistant, whose task is to hold the brake pedal in the cabin when fifth gear is engaged. When all this is done, you will have the opportunity to see all the ignition marks of the VAZ-2110.
6. We rotate the front wheel so that the lug on the camshaft gear clearly coincides with the protrusion on the rear timing drive cover. When they are aligned, take a flashlight and look at the position of the mark on the crankshaft pulley. It should point to the test point located on the oil pump cover. If they coincide, without letting go of the flashlight, we move to the engine compartment and compare the position of the marks on the flywheel crown. When the ignition is set correctly, it should also be aligned with the mark on the gearbox housing. In this case, everything is in order with the valve timing. The ignition marks are in their places. If, although the marks on the camshaft and the rear cover coincide, the tide on the crankshaft gear does not coincide with the point on the oil pump cover, it is necessary to make an adjustment.
7. Using a 17 key, unscrew the timing belt tensioner pulley. We remove the belt.
8. Without touching the timing shaft gears, rotate the wheel until the mark on the crankshaft pulley coincides with the marked point.
9. We insert a slotted screwdriver into the inspection window so as to immobilize the flywheel.
10. Carefully, so as not to change the settings, put the belt on the camshaft gear and crankshaft pulley. We tighten the tensioner pulley and fix it. Check to see if the marks have gone astray. If necessary, repeat the procedure.

This video covers all the nuances.

How to adjust contactless ignition

Before setting the ignition on VAZ 2101-2107 cars, you need to warm up the engine a little, without letting it stall.

You can adjust either by ear or using a special device called a strobe to set the ignition.

A strobe light is a device with which even a beginner can set the ignition correctly. For more information on setting up the ignition with a strobe, watch the video.

When is it necessary to set the ignition by marks?

Setting the ignition by marks is necessary when replacing:

• timing belt (scheduled or after a break);
• camshaft gears, pump, tension roller;
• crankshaft pulley;
• flywheel.

In addition, the ignition is checked and adjusted if problems arise with the timely ignition of the mixture. Most often, such problems are caused by the timing belt stretching or “licking” its teeth. If the belt “jumps” even one tooth relative to the mark, the engine will operate in emergency mode.

What is electronic or contactless ignition?

The electronic or contactless ignition system is a more advanced version of the SZ for cars. The block of such a device is assembled from electronic elements. Contactless ignition on a VAZ is called that way, because in this case the circuit is closed and opened thanks to an electronic switch. The latter, in turn, operates from a transistor, and not from a distributor contact, as was before.

The electronic ignition circuit on a VAZ has minor differences depending on the type of engine - injector or carburetor. In any case, this option is in practice more modern, as a result of which its popularity among our compatriots is growing. Due to differences in the connection diagram and some differences for the injector and carburetor, some car owners believe that the BSZ and the electronic system are different components, but this is not so.

BSZ scheme for the domestic “seven”

Switch Purpose

The non-contact ignition system is distinguished by the fact that the electrical impulse supplied to the coil (coils) is generated not by the breaker contact installed in the distributor, but by the switch. The electronic circuit of the latter supplies a spark to the cylinders with an optimal timing, based on data about the current operating mode of the engine and the position of the crankshaft at each specific moment.

The switch is able to withstand physical stress, vibration and temperature changes over a wide range. The absence of contacts in the circuit ensures greater reliability and durability of the unit. Another advantage of this solution is that the VAZ 2107 switch has the ability to be reprogrammed by the user to set the timing advance corresponding to the fuel quality and dynamic requirements for the vehicle.

VAZ 2107 switch parameters

The operating voltage of the switch is 13.5 volts, the permissible voltage range is from 6 to 16 volts. The maximum switching current is 8.5 amperes. The switch provides stable sparking in the engine speed range from 20 to 7000 rpm.

Why is it worth installing on “Seven”?

There are several reasons why you should install electronic ignition on a VAZ 2107.

Of course, it is important whether the engine is equipped with a carburetor or an injector, because the injection system does not have a distributor:

1. If you install such an SZ, the car owner will no longer need to periodically service the contact group. That is, you can forget about oxidation and cleaning of contacts, as well as adjusting the gap.
2. This VAZ 2107 ignition system is more reliable, since the contact group, which is most susceptible to breakdowns and wear, is simply absent.
3. In this case, the spark will be distributed more evenly and stably throughout the engine cylinders, and this will not be affected by the performance of the power unit.
4. The service life of the distributor as a whole increases as a result of the disappearance of vibration and shock of the axle in the case of the action of the so-called cams on the contacts.
5. If the VAZ ignition timing is set and the system is configured correctly, and the engine operates in normal mode, there is a chance of saving gasoline. During normal operation of the internal combustion engine, its power can also be increased, especially since as a result of complete combustion of the mixture in the engine cylinders, there will be fewer harmful emissions.
6. It will be easier to start the engine in cold weather, since the voltage level at the spark plugs will always be stable:

Signs of incorrect ignition timing setting

These include:

• the vehicle does not reach the maximum speed of the power plant;
• increased fuel consumption;
• the engine idles unevenly;
• the engine unit overheats;
• After the engine stops running, detonation occurs.

Correct installation of the VAZ 2106 engine ignition system consists of 3 stages:

The first stage is a change in the angle of contacts that are in a closed form. The second stage is setting the ignition timing of the VAZ 2106, and the third is adjusting the ignition system while the vehicle is moving. This ignition setting is carried out when the “six” is equipped with a contact ignition system or a transistor switch is installed.

1. Unfasten the latches of the breaker-distributor cover. With a contact system, we first clean its contact group with a needle file and test the degree of their interaction. If necessary, slightly tighten the fixed-type contact.
2. Using a special key for rotating the crankshaft, we select a position of the product when the contact gap becomes extremely large (if it is absent, we put the manual transmission in the 4th gear position and select this moment by moving the vehicle).
3. We unscrew the fasteners that secure the group of contacts on the bearing base.
4. Using a special set of probes, we select a product with a 0.4 mm template and adjust the gap between the contacts so that the template hardly passes between the contacts.
5. Screw in the fasteners and fix the position of the contacts.
6. We carry out verification measurements with 0.35 mm and 0.45 mm probes. In the first case, free movement in the gap of the contact group is allowed, and in the case of the second probe, the passage of the template is not allowed.

Installation Guide

How to install BSZ with your own hands on the “seven”? How to properly set and adjust the device? First you need to prepare everything you might need.

Tools and materials

To complete this task you will need:

• a set of keys;
• self-tapping screws;
• screwdriver set;
• construction drill.

Stages

Installation of electronic ignition must be carried out on a de-energized on-board network, otherwise a short circuit may occur in the system.

So disconnect the battery and then follow these steps:

1. Disconnect all high-voltage wires from the spark plugs.
2. Dismantle the distributor cover.
3. After this, by rotating the crankshaft, it is necessary to set the slider to a position perpendicular to the axis of the power unit. Also mark the location on the middle mark of the distribution element scale, this will allow you to make adjustments without any problems in the future.
4. The distributor fixing nut must be unscrewed, after which the device is dismantled.
5. A non-contact regulator is installed instead of the dismantled distributor, while the slider and housing must be placed in the desired position in accordance with the previously established marks.
6. The device cover is installed.
7. Then you need to connect the high-voltage cables with the spark plugs.
8. After completing these steps, you can replace the coil. In general, this task is quite simple, but when performing it, you should take into account the position of contacts B and K. If they are different on the new short circuit, then the element should be rotated relative to the fastener so that the contacts are located similar to the one that was installed previously.
9. At the final stage of installation, the switch is installed; the best option would be to place it between the washer expansion tank and the headlight. The mechanism is fixed using self-tapping screws, and the so-called zero wiring should be brought out under one of them. As for the radiator, it should be leaned against the body.

Repair and restoration of distributors of Japanese engines.

Distributor, also known as distributor, also known as ignition distributor, also known as ignition module.

In Japanese gasoline engine control systems, this is a technologically complex part that includes an electronic camshaft sensor, an electronic switch and a high-voltage ignition coil. The distributor is made as a single unit, it has its pros and cons. Unfortunately, the distributor is also sold as a single unit - this is a big, fat minus, because Currently, the cost of an “original” distributor at a dealer reaches 21,000-24,000 rubles.

Signs of distributor malfunction: Loss of engine power during acceleration; Unstable (“tweaking”) operation at idle; The engine is difficult to start and stalls when warming up; Popping noises in the intake or exhaust manifold during sudden acceleration; Engine computer memory contains a “misfire” error (loss of sparking) when scanning vehicles after 1996

Attention! You may be mistaken about the malfunction of your distributor. Similar symptoms are caused by other faulty components and components of the car. It would be more economically feasible for you to conduct electronic diagnostics and testing of the car’s ignition system

Contact us by phone: +7 495 9958674, +7 963 9777356 (Yuri), +7 495 7787546 (Alexander) or see the “contacts” page. You will receive maximum information, free consultation, and useful tips. The main reasons for distributor failure: Dirty engine injectors (look at the injectors); Old or “broken” spark plugs due to low-quality gasoline; Old, damaged or dirty high-voltage wires; “Lighting up” a car from a donor car with a faulty battery charging system; Dirty or cracked distributor cap; Oxidized, dirty battery terminals can also cause damage to the distributor. Malfunction of the generator and battery charging system.

Which distributor elements fail more often? According to our accumulated statistics - a switch and an ignition coil, and the probability of failure of both elements is the same - 50/50%. Repair of a distributor consists of replacing all its electronic components. Since the distributor body is quite reliable, we offer you the exchange of your faulty distributor for a restored one from our exchange stock. All distributors have been fully tested and tested on a special stand. We provide a guarantee on refurbished distributors. The components that we use when repairing distributors are only from original manufacturers, therefore reliable. When exchanging or repairing, we will definitely advise you so that you can avoid such troubles in the future. Services for dismantling, installing distributors, preventive cleaning of injectors and other related work can also be obtained from our “PAT auto” service center. In many stores, non-original Chinese-made distributors for Chrysler CIRRUS and Dodge STRATUS models with Mitsubishi 2.5L engines have appeared on sale. According to reviews from our clients and from our own experience, these “products,” unfortunately, do not justify their price (about 12,000 rubles). Upon careful examination, it turned out that the electronics of the switches are made of “consumer goods”, and the electrical insulation of the ignition coils is very weak. Our opinion is that such “miracle spare parts” are not intended for full and long-term work on these beautiful cars! In addition, they are usually not returnable to stores!

Adjustment features

As for how to set the installed ignition unit on the “seven”, then, of course, this procedure is best carried out using special equipment. But since such installations can only be found in car repair shops, the adjustment procedure can be done by ear. Before you begin the process, you need to make sure that both the carburetor and the pump are operating normally. The process itself is performed as follows:

1. First the engine warms up.
2. Then the distributor fixing nut is unscrewed.
3. The distributor itself should be slowly turned in different directions, while the motor should be running. The mechanism is turned until the operation of the internal combustion engine is smooth and the speed increases.
4. After this, the fixing nut needs to be tightened.
5. As for checking, to do this, you need to accelerate the car at third speed to about 50 km/h, then engage fourth gear and press the gas pedal. In this case, the sound of “fingers” or detonation should be heard from under the hood, which will last until the car’s speed increases by 5 km/h. If the sound continues longer, the distributor should be released and turned clockwise by about one degree. If you are unable to adjust the ignition yourself in this way, it is better to seek help from specialists - this procedure is inexpensive, but you will be sure that the engine will work normally.

Sorry, there are no surveys available at this time.

Checking the ignition angle while the vehicle is moving

It is best to check the functionality of the ignition system after any adjustments while driving. This is due to the design characteristics of the fuel dispenser and the octane number of the gasoline used. It happens that the ignition angles set according to the signs do not provide sufficient dynamics and throttle response. Adjusting the ear when detonation starts will help:

• We accelerate the car to a speed of 45-50 km/h on a flat section of the road;
• We turn on direct gear (on the fourth VAZ 2106) and fully press the accelerator pedal;
• A characteristic ringing sound (detonation) should appear, which will disappear after 2-3 seconds, and acceleration will be smooth and powerful without failures;
• If detonation does not disappear during the entire acceleration, the ignition angle is “early”;
• The complete absence of hum and slow dynamics indicate a delayed spark in the cylinders;
• We adjust the position of the distributor in place, turning it 3-5 degrees;
• When the adjustment is completed, the position of the distributor body relative to the block is marked with a line or paint.

Ignition adjustment work must be carried out regularly. The service interval for a simple contact ignition system is 15,000 km, for an electronic one – twice as long. The condition of spark plugs and high-voltage cables is also regularly checked. All installation operations are easy to do yourself; you don’t need a garage. The ability to independently repair the ignition of a VAZ 2106 is always useful on a long trip or in winter, when problems arise with starting.
