January 26, 2016 Lada.Online 112 760 2

The standard location of the Lada 4×4 generator is at the bottom, which cannot be called a good solution. During off-road driving, water and dirt easily get on it, or antifreeze drips, which significantly reduces its service life. To protect an important part from moisture, owners resort to modifications. Let's look at how to move the generator up to a Lada 4×4.

Scheme of moving the generator upstairs in Niva VAZ-21213

Niva is an excellent domestic SUV that can compete with modern jeeps.
VAZ 21214 received a durable body, a powerful power plant and a reliable suspension. Like any car it has its drawbacks. These include the location of the generator - the unit is installed in the lower part of the body. The problem can be solved by moving the generator upstairs.

After reading this article, you will learn:

What is needed to move the generator upstairs. How does the process work for cars with and without power steering? Is it worth buying a new unit for VAZ 21214.

Study this drawing carefully. The author decided to make a bracket for moving the generator with his own hands. The part is made of metal, the thickness of which should be 4 mm, and the width and length should be 80 mm. To assemble the bracket, you will need parts from other domestic cars:

Belt 6РК1290; Adjustment bar; Crankshaft pulley from tens.

As you can see in the photo, the standard fan is installed on a pump pulley from GAZ 3110, we also take a crankshaft pin from 2110 and a 6RK1290 brand belt. The generator should be located on the top left side. It must be attached to the top using an M8 cylinder head bolt; at the front, a standard bolt and studs are used. For fixation, the bracket must be secured with an additional lock nut.

This generator transfer drawing differs from the first one in that it uses a belt with a size of 1375 mm. There are fewer steps here, but you will have to work with a grinder - you need to reduce the plane on the head located in the area of the M8 bolt.

The front cover will need new bolts and studs. This drawing of a bracket for mounting a generator is also suitable for other models, for example, for 21213.

The drawing suggests moving the generator to the place of the hydraulic booster. To do this, you need to make a bracket and install it next to the power steering. You need to select washers for the bracket ears in advance.

This option uses a belt with a size of 1220 mm. It is important that the angle of its wedge must be exactly 40 degrees. An excellent solution would be to buy a belt with ZIL 157. The return hose has a center length of 1115 millimeters, and the high-pressure pressure hoses are 1450 mm. Check all dimensions carefully, remember the saying: measure 7 times, cut once, there is no need for mistakes here. There is no standard hole for these hoses in the right casing, so you will have to take it and cut it yourself.

If you don’t have much experience in carrying out such upgrades, then you can buy a ready-made kit. It will include a new bracket for the Niva and the necessary fastenings. Reviews from motorists indicate that the cost of this simple part is too high.

Should I install a more powerful current generation unit?

We have already described above why the unit wears out quickly. An excellent solution is to install a new generator. Another common reason is the installation of off-site equipment that consumes a lot of electricity. The current strength of a standard unit is not always enough, so you should think about installing a more powerful generator.

The model depends on the year of manufacture of the car and engine. For example, the first Nivas with a 1.6 power plant have a device with a remote regulator, which was used in the “classics”. In more modern machines the regulator is already built-in.

If you can modify the fastenings yourself, then the list of available gHepaTopoBs can expand significantly. Craftsmen even install devices from foreign cars.

In any case, you should strive to modernize and improve your car. And this applies not only to electricity. The Niva is a reliable SUV, but it lags far behind its foreign competitors in terms of comfort. You can move on to this issue immediately after improving the technical component of the car.

The author of the drawing made a bracket from a piece of metal 80x80 mm, 4 mm thick. The upper adjustment bar for the generator is borrowed from the Volga. It was cut in place and a new 8.5 mm mounting hole was drilled.

VAZ 2110 crankshaft pulley, GAZ 3110 pump pulley, 6RK1290 belt. A standard cooling fan is installed on the pump pulley. The location of the generator is top left. The lower mounting point of the fuel pump, at the front we attach it to a standard stud and bolt, and at the top there is an M8 cylinder head bolt. The lower long generator mounting bolt with an engraver and an additional locknut.

Another bracket drawing provides for a belt measuring 1375 mm. You will need to modify the plane on the head in the area of the M8 bolt with an angle grinder, and also change the studs and bolts securing the front cover.

Belt 1220 mm profile “A” (ZIL157), wedge angle 40 degrees. High pressure pressure hoses have a length at the centers of the fitting holes of 1450 mm. Return sleeve - 1115 mm. You will have to cut a hole for the hoses in the right protective casing. The belt is 710 mm long, other dimensions are the same. The photo on the left shows the hydraulic pump bracket, on the right - the power steering in the new place.

There are ready-made kits for moving the Lada 4×4 generator upwards on sale, but the price for a piece of iron can be greatly inflated. Thus, by making such a bracket ourselves, we extend the service life of the generator and save money.

Have you ever encountered such a modification? How did you solve a similar problem? Let us remind you that in another article we determine whether the Lada 4×4 needs a more powerful generator.

The Niva has excellent cross-country ability and can compete with many modern foreign-made jeeps. However, due to such a significant drawback, most owners of these cars experience significant inconvenience, and therefore decide to improve this vehicle. This can be done by moving the generator upward.

The fact is that during testing of the VAZ-21213 for cross-country ability, sand, dirt, stones and water may enter the generator. However, there is another, quite significant drawback - coolant constantly gets onto the generator. This problem can be solved by using the above method. But how to do it right?

It should be understood that if you use your VAZ-21213 in most cases for trips around the city or on the highway, then there is no need to move the generator. But if the Niva is used for off-road driving, then you simply cannot do without it.

In order to move the generator upward on the Niva, it is necessary to make a special bracket. It is made of metal, the thickness of which should not be less than 4 millimeters. Its width and length are about 80 millimeters. In order to assemble this device, you will definitely need some other spare parts from domestically produced cars. Namely:

adjustment bar;
belt 6РК1290;
crankshaft pulley suitable for VAZ-2110.

You will also need an upper adjustment bar, which can be borrowed from the good old Volga. To begin with, it should be cut in place, and then drill a new place for future fasteners.

A fan is mainly installed on the pump pulley from the Volga, and the generator itself is located at the top left. The cylinder head is attached on top of it thanks to an M8 bolt, while standard studs and a bolt are most often used on top. In order for the resulting bracket to hold well, it is best to secure it with another additional nut.

But there is also a second option for moving the generator on the Niva to the top. In this case, you should use a belt whose size is 1375 millimeters. You will have to perform much fewer actions, but you simply cannot do without working with an angle grinder. This tool will be necessary to reduce the plane of the head, which is located near the M8 bolt.

In addition, you will definitely need new studs and bolts for the front cover. By the way, this method is perfect for moving the generator up to the VAZ-21214.

It is very noteworthy that if you are the owner of a VAZ-21213 car, but you have no desire to perform the above actions yourself, but have a sense of saving, you can buy a ready-made set of spare parts. Finding it is quite easy, since it is sold in almost all stores that sell spare parts for the Niva.

Belt 1220 mm profile “A” (ZIL157), wedge angle 40 degrees. High pressure pressure hoses have a length at the centers of the fitting holes of 1450 mm. Return sleeve - 1115 mm. You will have to cut a hole for the hoses in the right protective casing. The belt is 710 mm long, other dimensions are the same. The photo on the left shows the hydraulic pump bracket, on the right - the power steering in the new place.

What is a generator

A generator is an alternating current device that produces electromagnetic excitation during operation. The generator design has a built-in rectifier unit, equipped with diodes made of silicon, as well as an electronic voltage regulator.

Thus, the unit creates electrical energy from mechanical energy and energizes the car’s battery, and also provides energy to its devices and systems. The connection diagram for the generator on Niva-2121, 21213, 21214 is shown in the figure.

Device Description

On Niva 21214 cars there is a generator of type 9412.3701, on VAZ 21213 - type 371.3701, on Niva Chevrolet there is a generator 2123. All of them are alternating current electric machines with electromagnetic excitation, having a built-in rectifier unit with silicon diodes and an electronic voltage regulator. The maximum current produced by the generator unit type 9412.3701 is 80 A, voltage - 13.2 - 14.7 V, rotation - right.

Design of unit 21214

The unit covers are attached to the stator using 4 bolts. The covers have bearings installed. They rotate the rotor shaft. In the front bearing, the inner race is clamped with a nut along with a thrust ring and washer. The 2nd bearing is also pressed into the back cover.

The stator has a 3-phase winding, one of the ends of which is connected to a rectifier unit consisting of 6 diodes. Of these, 3 diodes are negative, 3 are positive. According to the polarity, they are pressed into the plates. The entire structure consists of a rectifier unit, which is located on the back cover of the generator unit covered with a protective casing.

The design of the unit also includes contact rings and brushes. On the back side of the back cover there is a brush holder, which is structurally connected to the voltage regulator. The rectifier contains a capacitor that protects the electrical network from power surges.

The “B” terminal of the generator set must be connected to the positive terminal of the battery, and the negative terminal of the battery to the vehicle ground. If the connection is incorrect, this will lead to breakdown of the diodes.

Characteristics of the standard generator

The main characteristics of the generator installed by the manufacturer in Niva 21214, 21213, 2121 will be considered using the example of generator type 9412.3701:

current – 80A;
voltage – 13.2 V,
rotation is right.

The cost of standard models of electric generators is 5-7 thousand rubles. If the unit breaks down, it is possible to replace its components or completely replace it with the original or analogues. The prices of the most common ones are presented in the table.

Analogue	vendor code	Cost, in rubles
Generator VAZ-2104-21073,21214	9412.3701-03	5900
Generator VAZ-2104-21073,21214	372.3701-03/05	3800
Generator VAZ 2121-21213,21214	9412.3701	5450

The table shows that in the process of replacing a generator on a Niva, you can give preference to a cheaper universal analogue.

Generator faults

During the operation of any car, unpleasant situations often arise in the form of failure of one or another element. Niva is no exception, and most often the generator suffers.

If the generator seems to be faulty, it is recommended to check its functionality using a multimeter. To do this, you will need to start the engine and check the voltage at the battery terminals. The standard value that a multimeter should read is 13.6 V.

If the readings during measurement are higher, it means that a break or short circuit in the windings has occurred in the structure. The same can be said about the case when the voltage is below the specified number. This procedure is carried out regardless of the engine: injector or carburetor.

Also, if the breakdown is caused by another reason, you can replace the generator itself. Usually, for replacement, they turn to special service stations, but if necessary, the work can be done with your own hands.

How to move a generator in a field to the top

Now we take a grinder or a file and sharpen the engine block for the upper mounting of the bracket (the bolt to the left of the distributor, if they are located at the driver’s fender). On the block the tide has a round shape, but we reduce it to a rectangular shape!

We install the generator on the upper bracket and put on the belt. We check the alignment of the pulleys. If necessary, adjust the position of the bracket from the 214 generator. Install the tension bar. Let's tighten the generator belt!

We connect the wires, start the engine, check the voltage! (we didn’t succeed the first time due to a defective relay-regulator.

We inspect the engine compartment for the presence of jambs, making sure that they are absent, close the hood.

Niva is ready for new adventures!

Generator replacement

To repair or replace the generator, the car owner will have to remove the unit completely from the car or turn to professionals for work. If you still want to carry out the replacement yourself, then first you will need to prepare all the necessary tools:

hammer;
extension;
keys to "10" and "19".

The procedure consists of the following sequence of actions:

First, you will need to park the car in a place designated for inspection and repair. The car will also need to be secured using special wheel chocks. Finally, in order for the work to be carried out safely, you should disconnect the battery by disconnecting the terminals from it.
After this, you need to remove the engine protection. It is attached to several bolts, and they must be unscrewed to get to the lowest bolt of the generator.
After this, you will need to knock out the mounting bolt using a hammer. It is recommended to knock carefully so as not to damage the thread and to prevent the bolt from coming out in the opposite direction. A hammer is necessary, since a wrench or any other tool simply cannot handle a bolt.

Next, you need to remove the bolt, swinging the generator from side to side. It is necessary to bolt in any case, as this makes it easier to remove the rod.
The fourth step involves disconnecting the wiring. To do this, the power wires connected to the housing are disconnected from the unit. In this case, you can first disconnect the plug from the wires.

Wires are also attached to the generator, tightened with a nut or bracket. In this case, the nuts must be unscrewed with a wrench, and then the loose wires must be pulled out.

Finally, after disconnecting the wires, you can begin to unscrew the upper fastening element with the belt tensioner. For this you will also need a wrench, as well as a small extension cord.

Disconnecting the fastener will allow you to remove the belt and alternator. Then you can start cleaning the vacated space with a brush and installing a new unit.

The structure is assembled in the reverse order; the entire procedure will take about two hours if you have all the necessary tools.

Additionally, it is worth noting that when everything is assembled, you will need to adjust the position of the generator using the tensioner. To do this, you need to unscrew the tensioner nut and tighten or loosen the belt, while observing the battery charge.

If the indicator returns to normal, then the selected tension is sufficient. There is no need to tighten the structure, as the generator bearing may fail. If the tension is insufficient, the generator will work intermittently, and this can also lead to breakdown.

Nuances

When replacing a generator with a Niva 21213, 2121, 21214, a number of subtleties arise, and one of them is the location of the generator unit. It is located at the bottom of the engine compartment.

Actually, this is why problems arise with the operation of the structure: while driving, various contaminants get on the generator, and coolant drips. If you don’t want to constantly change the generator unit, it is recommended to move it upstairs.

To ensure that no problems arise during the operation of the car, it is important to monitor the condition of the car. First of all, it is recommended to regularly inspect the generator.

So, when the “battery” light blinks on the dashboard, if suspicious noises or creaking sounds occur, you should be wary and think that the generator is not working correctly.

Timely inspection will help to avoid unpleasant situations in the form of breakdowns of the constituent elements of the generator, and as a result, failure of entire electrical systems.

color - red, yellow material - steel
Price – 1100 RUR (light set)

The generator transfer bracket is designed to install the generator above the standard mounting point, because it, i.e.

The generator, when mounted at the factory (at the bottom of the block, almost at the crankcase), when operating the car starting from moderate off-road conditions, gets all the “goods” flying from under the wheels (water, dirt, snow, etc., etc.

) as a result, even when overcoming a small puddle, the battery charge often disappears, sometimes briefly, and sometimes completely (until you remove it and at least clean it, and it’s not easy to remove it from there, even in a garage, not to mention "conditions" far from civilization).
