A WARNING
When fixing the generator bracket, a longer bolt is set closer to the generator drive!
11. After installation, adjust the belt tension (see "Replacing and adjusting the tension of the drive of the generator drive 37.3701").

A few years after buying a car, a breakdown may occur. Most often, car owners face a problem in the generator. In order to get rid of the problem you need:

• remove the device;
• disassemble, detect an error, correct or purchase a new generator;
• install a functioning device.

Generator

In order to independently disassemble the parts of the car you need to know what they are intended for. Thus, the generator is a design that is designed to ensure that the electricity has occurred by electricity, by converting mechanical energy into the current. That is, the battery is charged during the motor operation.

Brief information:

• the generator is placed in the front of the engine;
• via crankshaft It is started.

To date, there are two types of devices: compact and traditional. Between them there are significant differences, for example, a different fan layout, a type of housing and so on. But the main details remain unchanged. Therefore, if the owner of the car at least once figured out the details on its own, then when dismising devices, another type can easily work. The components are the rotor, the brush unit, the stator, rectifier block.

Fastening the generator on VAZ 2112

VAZ 2112, the fastening of the generator should not cause difficulties, as practically in all brands domestic cars Installation occurs similarly. But in order for the work performed by their own hands, did not cause discontent to remember all the nuances.

1. Before making the generator fastening, on the VAZ 21124, it is necessary to make sure that the battery terminal with a minus has been disabled. This is one of the important items in the work, as in the opposite case, a closure may occur.
2. Next, it is necessary to position the generator correctly, while constantly holding it. Using the key number 13, spin the bolts, as shown in the photo below.
3. Install the stretch bar.
4. Taking advantage of the specialty key number 10, spin the adjusting bolt in the upper bracket.
5. Putting the generator belt correctly so that there are no breakdowns in the future.
6. Using the key number 10, screw the nut intended for fastening the wires to the generator drive with a plus polarity. Thus, both wires are installed.
7. Connect the device excitation wire.
8. Install the engine mudguard.
9. Include terminal with negative polarity to resume work. After full installation It is better to check the generator drive belt, you need to resolve the tension.

The fastening process is preceded by removal of the device, definition of breakage, subsequent repair. In order to relieve the design, you need to perform actions in the reverse order.

The operation of the machine cannot be continued if there are problems in the generator. It is necessary to check the device after a run of 15,000 km. Diagnostics determines the state and with any malfunctions, it is necessary to urgently correct the situation without delaying for later. The repair always includes the analysis of the part. To do this, keys number 10, 13. Most often, the reason is determined at the stage of demonstration of the main bolt of the rectifier block. If, the breakdown could not be determined to continue the analysis to the end.

Possible negative consequences

There are a number of consequences that may occur when installing the generator in the lower bracket. For example, due to the sleeve, the whole design is hardly included, the belt tension is carried out only after a special tension bolt has been tightened using key number 10. Nuts (№13) must be tightened after checking the belt, and its stretch should occur during the twisting of the nuts that are top.

In the event that the design was tightened much stronger than the laid, there will be rapid wear of parts, (such as the belt, pulley, bearings), and, therefore, the ambulance breakage. And the weak tension will result in spurious spare parts, a kind of whistle during operation, to the inability to charge the battery and subsequently, to its replacement.

Proper strap control

So that the generator serve for a long time it is necessary to determine the position of the belt.

1. The item should be slightly fade - approximately 10 mm, in the process of 10 kgf efforts between the device and the crankshaft pulleys. If the digit is different, then it is better to immediately adjust. First, it is necessary to reduce the upper nuts, as well as the lower generator.
2. Then to determine the entire design to the cylinder block, turning, with the right to the left (for the tangible belt release occurred). Therefore, in order to tighten, you need to do the steps in the opposite direction - to take the device from the cylinder, turn the bolt towards the left to the right, that is, clockwise.
3. Using the key, turn the crankshaft in the amount of two times clockwise using the pulley attachment bolt.
4. Next, you need to check the fastening check again. If the result is bad, it is better to immediately repeat the action.
5. Tighten the two remaining nuts.

There is also a second version of verification. Work is more convenient and better at the bottom of the car, but for this you need to remove the right front wheel. When replacing, removing the belt weaken the tension of nuts in the bottom, the top. The bolt intended for adjustment is turned to the limit value, the generator is elevated to the cylinder block and remove the belt. After inspection of the acting belt, you can start installing a new one. Initially, it is better to wear its crankshaft pulley, and then the generator itself.

Bracket

Most often, the cause of bad works of cars is not lined in the design itself, but in its bracket. The bracket fastening of the VAZ 2112 generator is fragile, since it is not made of metal. With the wrong setting of parts, the mounting of all nearby devices is attached, which, in turn, gives a crack on the bracket.

Many car owners complain that auto parts have to be changed every three months. So, for example, of all machines, the fastening of the VAZ 21124 generator is most often. In this case, it is better to consult with specialists and, if possible, make a metal bracket independently or order from the Master.

It must be remembered - the breakdown of the bracket is a kind of indicator indicating the existence of a skew, incorrect installation of the generator, excessive tension or loosening of the belt. Only after the reason is revealed and eliminated, the details will serve for a long time.

The described instruction allows you to understand the structure and stages of the installation of parts. But in order to better understand the sequence of actions, you need to familiarize yourself with the information provided in the applied video. What works from the fact that the work should be performed independently, then its price will be low.

With consistent actions, removal and installation will allow newcomers to better understand internal organization cars. The main motto in such work is attentiveness, since with improperly fastening or a small twist, deviation, in the future there may be a breakdown of many spare parts, which will lead to costs.

In the VAZ 2112 car, the generator is intended for powering electrical equipment with an engine man. If this node fails, the full operation of the car will be impossible, so the driver may encounter certain difficulties during ride. More information about the principle of work, as well as replacing some elements of this node you can read below.

Specifications and principle of operation of the generator set at the "twelsh"

First, let's consider the principle of operation of the generator 2112. One of the main elements of the design is the rotor performing the function of forming a magnetic field. This component is a shaft on which excitation winding is installed. Halves of this winding are installed in special poles, and the power winding current is carried out thanks to the contact rings. Rotation of the rotor is made due to belt transmission, from the drive.

Another, no less important component is a stator consisting of a core and winding. This mechanism produces an alternating current extended by electrical circuit through the contact rings. To supply the current on the rings, the design of the node is complemented by special brushes. After them, the diagram establishes a rectifier block used to convert the voltage that produces the device. Depending on the device model and its technical features, Different winding circuits can be used.

The generator node relay is used to maintain voltage within the set limits. This element changes the frequency, as well as the duration of electrical pulses. By its design, relays are several controllers, as well as executive components. The purpose of these components of parts is to determine the time during which the excitation winding must be connected to the network. In the event that the relay fails to rechargeable battery Unstable voltage will be supplied.

Concerning technical characteristicswhich has a generator on the VAZ 3701010-07, the voltage limits forming in the winding are 13.2-14.7 volts. The node itself allows you to produce current by force of up to 80 amps. It is important that the VAZ generator belt is tensioned properly, otherwise the operation of the device as a whole may be incorrect. If you want to check the belt tension with your own hands, then note that with a pressure of it with a mass of about 10 kilograms, the strap must be more than 8 mm (author of the video - channel in the garage at Sandro).

Service features

The need to repair the generator device on the VAZ 2112 16 valves occurs infrequently, but in order for the node to be repaired, it needs to be serviced correctly. In general, this unit has a rather high stock of reliability.

What are the features of the service to be observed to prevent repair:

1. It must be remembered that the outer surfaces of the unit should always be clean.
2. When serving, you also need to check the quality of the attachment of the node - it must be securely fixed at the installation site.
3. It will not be superfluous to check the performance of the voltage regulator, it uses a multimeter.
4. The same applies to the diagnosis of the belt. As mentioned above, first of all it is necessary to check its stretch - the belt should not be strongly stretched, but it is also not allowed. In addition, the diagnostics of the status of the strap should be carried out every 10 thousand km of run - it should not be traces of damage, cracks, also a belt should not be lazy.
5. Another point in service is to check the status of bearings. To diagnose, you need to dismantle the strap, and the node rotor must be rotated by hand. If during the rotation you felt a gap or even a slight jealous, then the bearing devices need to be changed. The same applies to the appearance of uncharacteristic sounds for their normal operation.

Possible malfunctions and ways to eliminate them

The need to repair the generator node may occur for various reasons. As practice shows, the most common of them is the failed brush or bearings. Read about the repair of these components below.

Procedure for replacing brushes

VAZ is made as follows:

1. First of all, it is necessary to press three latches on the device case, on its sides. These latches fix the cover to the mechanism.
2. The lid itself can be disconnected and removed to the side. So you can access the regulator.
3. There are two bolts on the regulator, fixing the device - they must be unscrewed. Then pull the knob and dismantle it.
4. Rate the status of the brushes - if they are workers, the length of these elements should be at least 0.5 cm. In the event that their size is less, then you have two options - either to repair it, replacing the brush, or change the device assembly. If repair is carried out, you will need a soldering iron, since the brush knot is soldered to the relay. To start, it is necessary to disappear wires connected to the brushes, and then dismantle the node, replacing it with a new and reliably solder it to the relay contacts. Either you simply change the relay, and make a further assembly of the device in the reverse order (author of the video - IZO channel))) Lenta).

How to change the bearings yourself?

To replace bearings, follow these steps:

1. On the dismantled generator, you must block the rotor, for this use a screwdriver, then unscrew the pulley.
2. Next, pulling the locks, you need to remove the device of the device. On two halves of the case, you need to make marks, and then using a screwdriver, you will need to dismantle the front cover.
3. Then you need to knock out the bearing from the landing place, it will need to be prescribed it for a more appropriate subject. Alternatively, you can use the head to 27.
4. After that, you can take a new bearing device and fill it with lubricant. This element should be scored through the old one. In order for the device to be more securely enshrined at the installation site, the edges can be collapsed with a chisel.
5. We now turn to the rear bearing. To do this, it is necessary to substitute either a thick screwdriver, or a thin chisel, and on top to hit several times with a hammer, in parallel to rearrange the screwdriver in the opposite direction. Dismantling the device can be carried out using a horn key.

Video "How to change the generator belt?"

Visual replacement instructions are given on the video below (the author is the channel in the garage at Sandro).

The thought of the generator substitution on the classics ancient, like the history of the car itself, because everyone who puts onto their own machine bells, more than a weak Chinese magnetol, native 42a-go M-221, everything is not enough.

True, even those who neglect the troubles with the installation of a more powerful generator, irritates the weak light of the near light on the XX and bad battery charge.
Somehow more familiar, slept to me on the ball, a 55th generator and an idea arose about telling you how to install it in our classics. Topping the Internet, to find at least something about installing and connecting, for a car, I didn't find anything, a lot of "stuck and forgotten" comments or long discussion of electricians of professionals, but they spoke in such a language that a common Russian man, it's like a Chinese song, nothing is clear ...))

In this regard, it was decided to write for ordinary people, of the articles, in order to help you choose, without any problems and special skills of working with an electrician, but with hands, to do this outstand procedure for replacing the generator.
Let `s start:
Alternatives at the standard generator there is a lot, as the generator with appropriate skills, means and desirable is allowed to put at least some. I inspect in the provided article only "economical" VAZ generators from other models, since:
a) they are cheaper.
b) they are more common, so you will not have problems with their substitution, the wrapping of components for their repair and the search for themselves.
c) they are easier to change them, you do not need to find or make any special fasteners and globally change the electrics.

With the features of Vazov generators, you will be able to familiarize yourself with the following diagrams:
42a:

The theory shows that even a more powerful 47a generator G222 from the genus VAZ-2105 is already significantly better than regular. Although, in practice, to be honest, there is no particular difference between them. By fastening and inclusion, it is quite suitable for 42a M-221.
The 55th generator will be more than enough to a person who uses the main electrical equipment of the car mainly. This is not a 80An generator, because if you prefer to apply a lot of additional equipment, I would not recommend it to you for installation and send interest to newer models. Although, if you have it used, a purely "tape recorder plus fog", it is completely enough. At the fastening of the 55a generator from the VAZ-2108, it does not differ from the standard M-221, so that here the problems appear in any way they don't have to take the old 42nd and put the fresh, the main thing is not forget to reset the terminal with the battery and pull the belt after installation.

The difficulties begin with the inclusion - as can be seen from the figure, 4 wires are used to the standard generator - 2 on the heel and 2 are inserted separately, and one is already inserted into the 55a wire. This is explained already integrated into the stress labeled generator, the so-called chocolate. Therefore, dark wiring from the relay (c) you need to isolate, they will no longer need them. Two wires with studs and you need to fasten to the hairpin 1, and the preserved yellowish wiring be connected to the plug 2.

Often, a lot of car owners of the VAZ 2110-2112 at the very first malfunction of the generator are in a hurry too much and prefer to replace it with a new one, instead of simply to find out the cause of the breakdown and eliminate it. In this case, we will not consider the repair of this device, but only let's look at the order of actions that must be performed for removing and installing the unit.

So, to dismantle it without problems, we will need such a tool as:

1. Face heads for 10 and 13
2. Ratchet handles or groves

Be sure to be disconnected by the car battery before starting the repair, removing the minus terminal. Otherwise, you risk getting a short circuit when disconnecting the plus wires of the generator.

Video on replacement

Especially for this post, I decided to make a video instruction in order to explain everything clearly and clearly.

If you have questions about a video review, you can ask them in my YouTube channel. Below will be presented in the usual format.

Photo repair report

I immediately want to warn that this example My VAZ 2110, the generator is slightly clamped by the mounting bracket, because during the accident it climbed it, so in all the subtleties show the order of removal. But still, the main points will be pretty clearly shown in the photo.

We unscrew the tensioner nut, which the arrow is shown below:

After that, move the generator backwards (in the direction of the car's salon), and remove the belt from the pulleys. Now you can disconnect all the power wires. One "bundle" is attached using a stud and nut, and another plug is simply fixed with the connector:

You can then unscrew the lower nut fastening of the generator, to pre-cut the machine and removing the engine protection (if installed):

Usually the bolt sits tightly, so it can be careful and without excessive effort to knock out a hammer handle:

After that, on the reverse side, we try to extract this very bolt to the end:

If you change the device assembly, the installation is carried out in the reverse order. But pay attention to the fact that the model of the generator can be like that was established by the factory. That is, first of all, look at the applicability specifically to your car, and then an indicator of current strength in amperes.

As for the price of generators for VAZ 2110-2112, it can vary depending on the type and manufacturer. But if you take a model of the shutter, which in most cases is installed by the plant, then the cost may be about 3500 rubles. Although Chinese options can be obtained almost twice cheaper. True, it is not necessary to chase at low cost, since the service life of the details can be quite low.
