The production of the VAZ “six” began in 1976. Cars of those years, and even more recent ones, even with proper and timely maintenance, require periodic repairs. Depending on the conditions and intensity of use, it may be necessary to repair both the body and individual components or assemblies. Many jobs can be done independently, if you have a certain list of tools and an understanding of what needs to be done and in what order. Therefore, it is worth going into more detail at the various stages of repair of the VAZ 2106.

The need to repair the VAZ 2106
The production of the VAZ “six” began in 1976. Cars of those years, and even more recent ones, even with proper and timely maintenance, require periodic repairs. Depending on the conditions and intensity of use, it may be necessary to repair both the body and individual components or assemblies. Many jobs can be done independently, if you have a certain list of tools and an understanding of what needs to be done and in what order. Therefore, it is worth going into more detail at the various stages of repair of the VAZ 2106.
Possible engine malfunctions
The resource of the power unit depends on the conditions in which it is operated. On average, a factory-assembled engine travels 150 thousand km before overhaul, sometimes the mileage reaches 200 thousand. During this period the following work will need to be completed.
- Adjustment of valves. On most cars produced, this is done using a dipstick or indicator bar, and only on cars produced in recent years can hydraulic compensators be found.
- During operation, it is necessary to change the generator drive belt. This is done after a visual inspection and detection of defects on it.
- Replacing the fuel pump rod. Over time, the part works and becomes shorter, the pressure on the pump lever weakens, as a result of which there is a lack of fuel at high speeds.
- The timing chain and gears need to be replaced as they wear out. Diagnosis of faults is simple: loud noise and inability to tension the chain. Together with this kit, the tensioner and damper shoe are replaced. Sometimes, along with them, it is necessary to change the drive gears of the oil pump and distributor, the so-called “pig”.
- Piston rings are usually replaced after 100 thousand kilometers. Their wear is characterized by loss of power, increased oil consumption and smoke from the crankcase ventilation pipe. To select rings, you should know that the diameter of the pistons in the VAZ 2106 and VAZ 21063 power units is 79 mm, and in the VAZ 21061 engine - 76 mm. Such a repair of the sixth model VAZ involves removing the cylinder head, so it often makes sense to grind the valves into the seats or change them.
Transmission repair
The VAZ “six” was equipped with two versions of manual transmissions - four- and five-speed. Both units are interchangeable. The VAZ 2106 gearbox is simple and at the same time reliable, which allows the owners of this car to carry out repairs themselves in case of problems. The main gearbox malfunctions are:
- oil leak;
- knocking out one of the gears;
- difficult gear shifting;
- extraneous sounds during operation.
One of the gearbox malfunctions is oil leakage.
Table: main faults of the VAZ 2106 gearbox and ways to eliminate them

Carburetor VAZ 2108 for VAZ 2101
Probably every driver who operates not new cars and maintains them in some part has independently encountered a problem related to the operation of the carburetor.
And then the thought came to mind of how to change the carburetor of a VAZ 2108 to a VAZ 2101.
If the carburetor is faulty, the car runs very poorly, has high fuel consumption, sneezes and sometimes does not start at all. This happened to me too.
My old VAZ 2105 with the old carburetor was already flatly refusing to work and there was nothing else to do but change the carburetor.
When replacing the carburetor, I decided to experiment a little and install not the original carburetor, but an “eight”, “Solex”.
To do this, we had to slightly alter the carburetor drive, since on the VAZ 2105 the drive comes through rods from the pedal, and on the VAZ 2108 through a cable. Otherwise, the carburetor is identical in terms of fastenings and fits into place without problems.
It’s not difficult to remake the drive; to do this, we simply make two rods, one from the gas pedal to the intermediate lever, on which, on one side, there is a cap that is put on the intermediate lever, and on the other side, a hook that attaches the rod to the pedal.
The other rod has caps on both sides that cling to the carburetor and the intermediate lever. You can buy a ready-made drive at the car market.
Also, the Solex carburetor has an idle speed solenoid valve installed, and therefore it was necessary to supply power to it. Power to the valve should be supplied immediately after turning on the ignition, so I took it from the ignition switch.
As soon as the ignition is turned on, power is supplied to the valve and it opens. Although, again, if you replace the ignition system with an electronic one from the same “eight”, then you can control the solenoid valve from electronics - EPHH, which ultimately will give a small fuel saving.
And let’s not forget to change the air damper cable from the eight, too, since it is longer. And the standard cable will not reach, because it will be attached to the carburetor on the other side.
As a result of replacing the carburetor of a VAZ 2108 with a VAZ 2101, I got a completely different car, it became much faster at the start, the engine picks up speed well and in addition the car became a little more economical.
For 100 kilometers, the car began to take fuel approximately 1-1.5 liters less than with the original carburetor.

Overhaul of VAZ 2106
The overhaul of a sixth model Zhiguli or any other car is usually understood as a complete disassembly of the units or body in order to eliminate certain malfunctions. If we are talking about body repair, then during its implementation any defects (corrosion, dents, etc.) are completely eliminated, followed by preparing the car for anti-corrosion treatment and painting.
When overhauling a VAZ 2106, the body is completely restored or the units are rebuilt
When a complete repair of any unit is carried out, in most cases, gaskets, lip seals, bearings, gears (if they have a large wear rate) and other elements are replaced. If this is an engine, then during a major overhaul the crankshaft and cylinders are bored, the camshaft and piston group are changed. In the case of the rear axle, the main gearbox pair or differential box assembly is replaced, as well as the bearings and seals of the axle shafts. If the gearbox breaks down, the gears and synchronizer rings of a particular gear are replaced, and sometimes the input and output shafts are changed.
VAZ 2106 is an easy-to-maintain car. Almost every owner of this car can repair the body or any mechanism with his own hands, and this does not require special and expensive tools, with the exception of a welding machine and any measuring instruments. However, you can also borrow them from friends. If you have certain skills in automobile repair, then restoring the functionality of your personal vehicle will not be difficult.
Operation and repair of the device
The carburetor serves to form a combustible mixture by combining injected fuel and air, in order to ensure the operation of the internal combustion engine. In this case, the correct proportions must be observed to ensure normal combustion. If the proportions are not observed, an over-enriched mixture is formed due to an excess amount of fuel or lack of air, which leads to breakdowns.
The carburetor includes a system that maintains the required fuel level; a system responsible for starting and warming up a cold engine; idle system; main dosing system; acceleration pump; econostatic system. Adjusting the idle speed of the VAZ 2105 should be performed exclusively on the engine, which is warmed up in advance. The temperature value of the coolant should fluctuate around 90-95 degrees.
In addition, you need to adjust the gaps on the gas distribution mechanisms and open the air damper
Special attention should be paid to the correct setting of the ignition timing. When adjusting the 2105 carburetor, first of all, set the crankshaft rotation frequency to 700-800
This process is carried out by means of a screw that regulates the composition of the mixture, after which the same screw achieves a carbon monoxide concentration of approximately 0.05.2% reduced to 20 ° C and 760 mm Hg. Art. with the screw in the above position. After this, using the first screw, you need to restore the crankshaft rotation frequency to 700-800. Using the second adjustment screw, the carbon concentration value can be restored as a percentage to 0.05.Jan.2.
Then, by sharply pressing the throttle drive pedal and then releasing it, the engine will increase the crankshaft rotation frequency, and if it decreases, the engine will stall. In this case, using the first screw, you should again increase the rotating frequency to 750-800, after which a plastic plug is installed in the hole for the second adjusting screw. After all these steps, the adjustment process 2105 is considered complete.
When installing a carburetor on a classic VAZ 21053, you should remember that, unlike the VAZ 2105, 21053 20 has a somewhat poor second chamber. This is explained by the fact that the first has a fairly rich adjustment. It can be made poorer by installing 102-150 jets, but then there will be a need to enrich the second chamber by installing 115-135 jets.
Considering the technical characteristics of the VAZ 2105, of course, it is necessary and more advisable to install the 2105 Ozone carburetor, but still, installing the 21053 20 carburetor is also considered acceptable. In order to increase engine power and the efficiency of the VAZ 2105 carburetor, a compressor is usually installed on the car.
The compressor consists of a pulley, a drive gear, a rotor driven gear and an internal oil gear. All installation work should be carried out with the engine cool. After installation, the compressor should have minimal resistance to air movement. Typically, an installation kit is used for this, which includes all the necessary parts. A mechanical supercharger (compressor) plays an important role in the process of improving the quality of a car.
