Adjusting the gap between the contacts of the VAZ 2107 breaker

8.1.3. Adjusting the gap and closed state of the breaker contacts

If you have a meter for the duration of the closed state of the breaker contacts, the most accurate method for setting the gap between the breaker contacts is to measure and set the duration of the closed state of the breaker contacts.
The closed state angle of the breaker contacts is the angle through which the ignition distributor cam rotates while the breaker contacts remain closed. The advantage of this method is that any wear on the distributor shaft and cam circuit is taken into account, and measurement errors when using a feeler gauge are eliminated.

How correctly the ignition system is configured in your car has a strong impact on the overall performance of the car. Therefore, it is necessary to know exactly what actions will have to be taken if the VAZ 2106 distributor suddenly fails.

Adjustment methods

In general, system adjustment is carried out in three stages. The first includes adjusting the angle of the closed state of the contacts. Keep in mind that it depends directly on the size of the gap in the contacts of the distributor. The second stage includes setting the angle at which the ignition advance occurs, and the third stage allows you to check and correct the results obtained. It is necessary to pay special attention to the fact that all results must be clarified directly during the driving process.

Adjustment will be needed if you use a classic or transistor ignition system in your car. In order to get started, you will first need to remove the cover covering the ignition distributor of the VAZ 2106. If your VAZ 2106 has a classic system installed, then before you begin the adjustment process, clean all the supplied contacts and check the care with which they fit to each other.

If you notice any deviations, carefully put the system in order by bending the necessary places in the contacts. Next, turn the crankshaft so that the maximum permissible distance is formed between the contacts of the VAZ 2106 distributor. Then unscrew the screw that secures the group; it is located on the bearing plate. And insert the probe, the thickness of which is 0.5 mm. Move the contacts so that it can move with little force.

Once you think you have achieved the optimal result, tighten the screw to secure the position. To find out whether you have spread the contacts correctly, place a slightly thicker probe between them. If it does not pass between the contacts, you managed to do a good job.

To rotate the crankshaft, use a special wrench. If you don't have one, start moving the car slowly with fourth gear engaged. Of course, this will require some effort, because using a starter to carry out such work becomes almost impossible. This is due to the fact that it will be quite problematic to find the optimal rotation angle.

Proceed to directly measure the angle. Remove the high voltage wire from the distributor cover and connect it to the car. Next, using the ignition coil and the 12V bulb attached to it, attach to the wire that runs directly from the distributor to the coil.

If the installation was completed correctly, when you turn on the ignition, the light will start to light, and as soon as you open the contacts, it will go out. Then start rotating the engine crankshaft so that it moves clockwise. This work must be carried out until the light goes out. Remember the position in which the slider is located and mark it somewhere for yourself.

No current passes through breaker contacts

Distributor repair

Replacing the distributor with your own hands

If you need to replace a VAZ distributor, keep in mind that all parts that have become unusable during this time will also have to undergo this procedure. In order to repair the distributor, you will need the following parts:

• keys 7 - 2 pcs.;
• keys for 10 and 13;
• screwdrivers - 2 pcs.;
• a set of flat probes;
• hammer;
• mandrels, which are used to press out and press in bearings;
• tweezers.

The distributor rotor has two fixed screws that will need to be removed. Keep in mind that they are attached directly to the timing adjuster support plate. After this, you can carefully remove the rotor. All springs and weights that are removed from the centrifugal regulator responsible for ignition timing must be numbered.

This must be done so that when the installation is carried out, all small parts in the VAZ 2106 ignition distributor are installed correctly. Holding the nut installed on one of the moving contacts with one hand, unscrew the one that is located next to it and is responsible for fastening the tips of the condenser wires and the wire leading to where the VAZ 2106 ignition distributor is located.

Adjusting the ignition on a VAZ 2106.

If the car is equipped with a classic ignition system, then before starting the adjustment, it is advisable to clean the contacts of the distributor with a file. After cleaning, we check the condition of the contacts - you need to make sure that the contacts are in contact with each other along the entire plane.

If the need arises, the contacts will have to be adjusted. Now we turn the crankshaft to a position at which the distance between the contacts will be maximum . We unscrew the screw that secures the contact group on the bearing plate,

now we insert the probe - its thickness should be approximately 0.4 mm between the contacts,

After that, the position of the contact group is selected , at which the probe will move with little effort , this position must be fixed.

If this is not the case, then put it in fourth gear and carefully push the car. You won't be able to use a starter because it's almost impossible to get the right angle of rotation. The gap resulting between the contacts of the distributor gives the necessary value to the UZSK , do not forget that the angle is critical, not the gap ! It is precisely because of this that you need to check the adjustment by measuring the angle, which is approximately 55±3°

.

The simplest option is to use an electronic tachometer, which has a UZSK measurement function. To use this device, you need to assemble the distributor and start the engine. The tachometer must be switched to UZSK measurement mode.

If the UZSK goes beyond the limits recommended by the manufacturer, the gap adjustment will have to be repeated. There is another way, in which you need to measure the angle. The first thing we do is pull out the central explosive wire from the distributor cover and hook it to the ground of the car, you don’t have to pull out the wire, but then there will be a risk of a breakdown in the coil. To the wire going from the distributor to the ignition coil, you will need to connect 12- Ti volt light bulb.

The light will light up if the ignition is on and the distributor contacts themselves are open, and go out when they are closed. If a thyristor or transistor system is installed on the car, then the light bulb will not light up when the contacts are open , due to the fact that there is a current limiter. Then the light bulb will have to be replaced with a voltmeter; in the open contact position it shows 12 V, and in the closed position - 0.

We turn the crankshaft clockwise , you need to turn it until the contacts close . this position of the slider ; it is advisable to mark it on the distributor. The crankshaft must be rotated until the contacts open.

We remember this position of the slider, then measure the angle between these two positions. This is done like this: we measure the length of the circular arc using the distributor body, then calculate the angle in degrees using the formula:

Contactless distributor

The device of the VAZ 2101 non-contact type breaker-distributor is similar to the contact type. The only difference is that the mechanical breaker is replaced by a Hall sensor. This decision was made by the designers due to the frequent failure of the contact mechanism and the need to constantly adjust the intercontact gap.

In a contactless ignition system, the Hall sensor acts as a breaker

Distributors with a Hall sensor are used in non-contact ignition systems. The design of the sensor consists of a permanent magnet and a round screen with cutouts mounted on the shaft of the chopper-distributor. As the shaft rotates, the screen cutouts alternately pass through the magnet groove, which causes changes in its field. The sensor itself does not generate an electrical pulse, but only counts the number of revolutions of the distributor shaft and transmits the received information to the switch, which converts each signal into a pulsating current.

Adjustment with strobe light

We hook the strobe light to the car's network. You need to remove and plug the vacuum corrector hose from the distributor. Now the engine needs to be started and warmed up to a temperature at which it will stable idle speed. Then you need to loosen the bolt that secures the distributor body. The strobe light must be directed at the pulley, which is located on the crankshaft.

Now we begin to turn the distributor until the mark on the pulley aligns with the marks on the timing cover . In this position, the distributor body is fixed.

Adjustment "light"

This method is considered classic, as it can be found in all automotive literature. Take a 12 V light bulb and connect two wires. When the light bulb is prepared, you can begin. The crankshaft must be rotated so that the pulley mark is positioned in a given way, in relation to the marks on the timing cover , the distributor slider must be opposite the explosive wire of the 1st cylinder.

I repeat, if there is no special key, then we turn on fourth gear and push the car . One of the wiring of the light bulb is connected to the wire that goes from the distributor to the ignition coil, the second wiring must be connected to the ground of the car . The central wire is removed from the distributor cover and connected to ground. The bolt securing the distributor must be loosened.

Now turn on the ignition. The distributor body must be turned clockwise until the light goes out . Then you need to carefully rotate it in the other direction; as soon as the light comes on, we stop rotating - it is in this position that you need to fix the distributor.

How to check Uzsk?

UZSK can also be determined using an arrow pointer. The arrow is cut from the tin of a tin can and installed under the screw of the rotor of the breaker (runner) or made of wire and attached to the rotor with plasticine.

Spark adjustment

We put the crankshaft in the desired position, pull out the central wire from the distributor cover, and fasten it at a distance of about 5 mm from the ground.

Loosen the bolt that secures the distributor housing, then turn on the ignition. The distributor body must be rotated clockwise by 10-20 degrees . Then you need to slowly rotate in the opposite direction until a spark strikes , then secure the distributor body.

Checking the adjustment results

Let's move on to the last stage, we need to check the results obtained. The results are checked based on the car's behavior on the road. You need to warm up the engine, drive out onto a flat section of the road, pick up a speed of 40-50 km/h, engage fourth gear and sharply press the gas pedal . Within 1-2 seconds, characteristic knocking sounds similar to clattering will be heard, and the car will immediately begin to confidently pick up speed.

If no sounds are heard, then you need to turn the distributor counterclockwise one notch, this procedure must be repeated until a sound is heard.

The cause of the malfunction may also be a deviation of the fuel composition from the nominal one, as well as incorrect operation of the distributor systems.
