This article will talk about how the ignition is installed on a VAZ 2107. On this car, both contactless and contact ignition systems can be installed. Regardless of which system design is installed in the car, all work is carried out almost identically. The appearance and drive of the BSZ trambler and the contact are the same, the only difference is that in the first, instead of a mechanical chopper, a Hall sensor is used. There is also a difference in the power wire that connects to the distributor.
Tumbler Replacement
To make a complete replacement of the distributor on a VAZ 2107 car, you need to use only one tool - the key to “13”. First, disconnect from the cover all the wires that go to the spark plugs. A hose is laid between the carburetor and the distributor for the normal functioning of the vacuum ignition timing controller. A small wiring harness goes to the ignition distributor. He connects to him with the help of a block. After that, unscrew the nut that secured the distributor casing to the internal combustion engine block.
Do this with the key at "13". Remove the washers and plate. Slightly pulling up, you can remove the toggle switch housing from its place. The cost of the new distributor for the VAZ 2107 car, as well as for the entire classic series, is approximately 800 rubles. In the event that it is planned to install a non-contact ignition VAZ 2107 instead of the classic one, you will have to spend about two thousand rubles. This is the average value of a shopping kit.
Why adjustment is needed
Everyone knows what the ignition timing is. This parameter of the system must be adjusted from time to time on any car equipped with a classic ignition system. This is done in order to reduce gasoline consumption, increase the life of the internal combustion engine, and also in order to achieve the best characteristics of the dynamics and throttle response of the car.
You can divide all the procedures into several stages. Firstly, the angle of the contact group in the “closed” position is adjusted. Secondly, after this it is only possible to begin work ahead of the ignition angle. Fixation is made in the most acceptable position. On the VAZ 2107, the ignition installation is not yet finished, it is necessary to adjust the settings.
Adjustment settings
Having completed all these actions, it is necessary to make a test run in order to carry out more precise control and make adjustments. In case suddenly any irregularities appeared during engine operation. The angle of the contact group in the “closed” position can be determined by the size of the gap of the group. This is extremely necessary to do in distributors, which are used in contact and transistor ignition systems. But the non-contact ignition VAZ 2107 does not need such adjustments.
Contact Group Adjustment
So, now in more detail about how to properly configure the ignition system on the six. First remove the cover from the distributor. Use the ratchet wrench to crank the crankshaft until you notice that the distance between the breaker contacts is at its maximum value. The contact group was fixed using two small bolts, for adjustment they need to be slightly loosened. If there is a contactless ignition of the VAZ 2107, then you only need to set the lead angle.
This is best done with a key, not a screwdriver. As a rule, the tightening of these bolts is very strong, so you are more likely to damage their heads. For proper adjustment, you will need a probe with a thickness of 0.44 mm. Install it between the contacts and fix the position of the breaker. To do this, tighten both bolts. Using this procedure, you can achieve the desired angle at which the contact group is closed.
Closed angle
For a VAZ 2107 car and similar models, the most suitable angle is 55 degrees. The error should be no more than three degrees. After adjusting the angle of the closed state, you must go to the next step. You should install the distributor so that the ignition timing is perfect. Please note that setting the lead angle on engines that have significant wear is best done on the fourth cylinder. The adjustment on the first cylinder is only possible on new engines or after major repairs.
Ignition timing
Of course, you can make adjustments by ear, but this is not very correct. The correct setting of the ignition moment of the VAZ 2107 is necessary in order to reduce fuel consumption, increase engine life. Before adjusting, remove the hose from the vacuum corrector. And plug the hole in the corrector. Warm up the engine to operating temperature to maintain idle speed at a normal level. Stop the engine and unscrew the nut that secured the ignition distributor housing.
Strobe setting
The strobe must be connected to the minus and plus of the battery. A capacitive sensor is put on the armored wire of the cylinder through which the adjustment is made. Now about how the ignition installation on the VAZ 2107 occurs. Light is emitted from the strobe. Its beam must be directed to the crankshaft pulley. To correctly set the ignition, you need to install the distributor housing in a position in which the strobe, the beam of which is parallel to the mark on the timing cover , slips at the moment when the mark on the crankshaft pulley is opposite it.
Please note that after the setup is complete, you must still check the correctness on the track. To achieve the required ignition timing, you will need to rotate the entire distributor housing in the right direction. After finding the desired position, fix it with a nut. Similarly, the VAZ 2107 contactless ignition is installed, the timing is adjusted in the same way.
How to check the settings on the go
To make sure that all work is done correctly, you must go to the track. Warm up the car and disperse it on a flat road to 50 km / h. In this case, it is necessary to turn on the fourth speed and move evenly. Sharply press an accelerator pedal. There should be short (about two seconds, no more) knocks that give out in detonation. In this case, the car should gradually increase its speed. On the VAZ 2107, the ignition installation can be considered complete if all conditions have been met.
In the event that you do not hear knocking knocks, you need to turn the distributor case counterclockwise (maximum by one division). Conversely, if knocking lasts longer than 2 seconds, rotate the housing clockwise by a maximum of one division. If, when conducting tests on the highway, you have achieved that the position of the distributor housing has changed much than it was set when setting with a strobe, then you can only judge about the presence of a breakdown in the internal combustion engine.
What to consider?
Of course, such symptoms can be triggered by improper mixture formation in the carburetor. Before you install the ignition on the VAZ 2107, you need to make sure that all systems are working stably. It is also possible that the vacuum regulator in the distributor is not working properly. It is possible that the bearings and bushings of the ignition distributor have very high wear.
If the adjustment is correct, no malfunctions were found, then you ensure that the motor starts and its operation will occur as stably as possible. The dynamics of the car improves significantly, the consumption becomes lower, the engine resource increases several times. Therefore, the correct adjustment of the ignition timing will allow you to repair the engine and its systems as rarely as possible. And the ignition scheme of the VAZ 2107 is simple, identical to that used on all classic models.
