Moving the generator upstairs Niva 2121 with your own hands

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. When testing for strength in forest and mountainous areas, dirt, sand, and water get into it.

Another unpleasant point is that coolant constantly drips onto the unit. The problem can be solved by moving the generator upstairs.

It is worth carrying out such an upgrade if you often use your Niva on real off-road conditions. Under normal conditions, the location of the part does not matter.

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.

Even a novice car enthusiast can understand the diagrams and drawings in this article. Photographic materials will also help you understand the information. To carry out the work, it is worth preparing in advance a set of wrenches, torsion bars and other standard tools.

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.

How to replace power steering fluid in a Chevrolet Niva

The power steering system itself is a Chevrolet Niva hydraulic system, part of the steering mechanism to make it easier to turn the steering wheel and set the trajectory. If the power steering fails, it is possible to drive the car, but the steering wheel will be difficult to turn and will become heavy.

The power steering fluid level in a Chevrolet Niva can be determined by the marks on the plastic power steering expansion tank.

During operation, Chevrolet Niva power steering fluid can leak in various places, most often through hoses. As a result, the power steering oil level will drop.

Driving without fluid in the Chevrolet Niva's power steering puts you at risk of breaking the power steering pump, which costs a lot of money, since it will run dry. As a result, it will suffer serious damage and fail. The power steering pump in the Chevrolet Niva starts working as soon as you start the car. If your Chevrolet Niva is left without oil in the power steering system, then the best solution is to call a tow truck.

Intensive use of the Chevrolet Niva makes the color of the power steering oil darker over time, often with a burning smell.

This is a reason to think about replacing it. Overheating of the oil often occurs when the steering wheel is held in the extreme position for a long time, until it boils; the pressure in this case is maximum. You should also not leave your car parked for a long time with the steering wheel turned all the way.

Quick prevention and inspection of Chevrolet Niva power steering includes:

monitoring the power steering oil level and its quality in the power steering expansion tank, checking the tension of the drive belt on the Chevrolet Niva power steering pump, assessing the condition of the hoses - cracks, leaks, fogging, as well as searching for leaks at the joints of power steering elements.

There are two ways to replace the fluid in the Chevrolet Niva power steering:

partial replacement of power steering fluid for Chevrolet Niva.
complete replacement of power steering fluid for Chevrolet Niva.

To partially replace the power steering oil, you will need a syringe (with a tube) and the oil itself, enough so that at the end of the work it will no longer be dark.

Partial replacement of power steering fluid in Chevrolet Niva:

Unscrew the cap of the Chevrolet Niva power steering expansion tank.
Using a syringe with a tube, completely pump out the fluid from the power steering reservoir.
Fill the reservoir with new fluid to the MAX level.
We start the engine and turn the steering wheel left and right to the extreme position.
We turn off the engine and repeat step No. 1 again until we get the required result - light oil.

The following method for changing power steering oil in a Chevrolet Niva will allow you to achieve almost 100% replacement.

Basic malfunctions and ways to eliminate them

Checking the health of the unit is done using a multimeter. After the engine is started, the voltage at the battery terminals should be 13.6 V. If the value is higher or lower, this indicates a break or short circuit of the windings, oxidation of the slip rings, a malfunction in the brush assembly, or voltage regulator.

The generator unit may not work well due to weak belt tension or its breakage. In this case, you need to adjust the tension or replace the belt. Faulty voltage regulator, needs to be replaced. If a breakdown, short circuit, or damage to the rotor windings is detected, it should be replaced. If there is a break or short circuit in the stator windings, it requires replacement. If the diodes are damaged, the rectifier unit is replaced.

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!

Guide to removing and connecting the generator

To remove the unit, you need to prepare a set of tools: keys “10” and “19”, ratchets with heads, a hammer and a small extension.

The process consists of the following steps:

First of all, remove the negative terminal from the battery.
Next, you need to remove the engine protection and the right mudguard.
Then, using a hammer, carefully knock out the mounting bolt and remove it.
At the next stage, you need to disconnect all the wires going to the generator: the plug and the wires secured with a nut.
Then the fastening on which the belt tensioner is located is unscrewed.
By removing the belt, the assembly can be dismantled through the hole that was formed after removing the protection.
After replacement or repair, install the unit in reverse order.

The generator is connected according to the diagram.

Price issue

The VAZ 21214 generator has good repairability, which allows you to significantly save money if worn or broken parts are replaced in a timely manner.

If you change the complete unit, the cost of replacement will be as follows:

generator 21214 – 3125 rub.;
lower mount – 133 RUR;
fastening bolt - 53 rub.;
tension bar - 55 rub.;
relay RS-527 – 57 rub.

Moving the generator upstairs in Niva

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.

Also interesting: Non-adjustable wheel bearings for the field

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 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.

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.

Keywords: 4x4 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.

Another unpleasant point is that coolant constantly drips onto the unit.

Operating principle of the hydraulic control system

In the video below you can watch how a self-installed power steering works (the author of the video is Vladislav Mantula).

rdoctor: Power steering, unlike electric power steering, dampens the transmission of impacts from the wheels to the steering wheel - when hitting a pothole at speed, the steering wheel will not be torn out of your hands. Actually, this is the main (and perhaps the only) plus of the power steering. The power steering uses a standard steering gearbox. With a booster, you will be spinning the wheels more often on a stationary car, which will shorten the life of the standard RR. The power steering comes with its own gearbox.

As for the rest, the EUR has only advantages. Price, ease of installation. And the fact that if the power steering malfunctions, you will simply get a standard steering wheel, and not a steering wheel that can barely be turned (although we have never heard of malfunctions in our power steering).

But the question is... Does our Nivsky power steering change the force on the steering wheel depending on the speed, or not? I want the steering wheel to stiffen as the speed increases, and not remain weak. As far as I understand, the power steering monitors the speed (does it really load the steering wheel as it increases?) And the power steering? Is he just unloading? Or does it still track? (how does it track, by the way, if it does track?)

People, let me know who installed the Nivo EUR, how is it in terms of quality? I want to buy it, it’s cheaper than the Priorovsky one and the lock, the steering wheel and steering columns don’t need to be changed, everything is original. The only difference is that the Priorovsky one has height adjustment.

How does power steering work? Its main element is a pump, which, using a belt from the crankshaft, sucks in oil and pumps it into the distributor. The latter, in turn, monitors the force applied to the steering wheel and, using a torsion bar (follower device), helps turn the drive wheels. When moving in a straight line, the torsion bar does not twist, so the distributor channels are blocked and the oil drains back into the reservoir.

Power steering is most often useful when parking and turning, making the work of your hands three times easier. We can also say that the mechanism weakens the transmission of microshocks from the road surface to the steering. The mechanism is also useful in case of a sharp drop in tire pressure. The disadvantages of power steering include the fact that it interferes with “feeling the car”, so designers need to achieve a compromise between informativeness and tightness of the steering wheel.

Foreign manufacturers conduct a lot of research in order to make the hydraulic booster light at low speeds and elastic at high speeds. To do this, German hydraulic boosters from ZF are equipped with pressure modulators, which limit the oil pressure in the operating circuit as speed increases. In addition, circuits with power steering driven by an electric motor are acceptable, which makes it possible to change the pump performance in accordance with the rotation of the electric drive. Sometimes the gear ratio is also changed.

Alternator belt tension VAZ 21214 injector

We check the belt tension by its deflection between the pulleys of the units. 1. With normal belt tension, its deflection under a force of 98N (10 kgf) should be 10–15 mm between the pump pulleys and the generator

. . or 12–17 mm between the pump and crankshaft pulleys. We adjust the belt tension by shifting the generator (with its fastening nuts loosened): from the engine to increase the tension or to the engine to decrease the tension.3. To replace the belt, loosen the nut securing the generator to the tension bar with the “17” head on the carburetor engine.4. . or a “13” head - on an injection engine. We move the generator towards the cylinder block to loosen the belt tension.5. We move the generator, acting on it with a screwdriver as a lever in the slot of the tension bar:

on a carburetor engine;

6. on a VAZ-21214 engine.

Install the belt in reverse order. Turn the crankshaft clockwise two turns and check the belt tension. Excessive belt tension causes increased loads on the generator and pump bearings.

The original alternator belt on a VAZ 2121 can serve the driver for about 100 thousand kilometers on domestic roads, such messages came from many owners of the people's favorite. But it is not always possible to find an original alternator belt on the automobile market; the problem is that sellers tend to deceive gullible customers and the service life of the basement belt can be reduced by 2-3 times. Today we will tell you how to replace the alternator belt on a Niva with your own hands in a garage.

When you already have a new alternator belt in your hands, you need to prepare a 17-mm open-end wrench and a convenient place for repairs. As people say, I'll leave this video here.

Video. DIY alternator and drive belt replacement

1. The image shows how to properly loosen the alternator belt tensioner nut.

2. When the nut is slightly loosened, you need to move the car's alternator to the side to have good access to the belt. The arrow in which direction you need to move the generator is shown in the photo.

3. Remove the belt from the pump pulley, see the image for more details.

4. The alternator belt has been completely removed, now you can begin installing a new one.

The cost of a new belt is about 100 rubles. We carry out the installation in the reverse order, also do not forget about tensioning the alternator belt, you can watch the video above about this operation.

Insufficient tension on the alternator belt can also lead to its failure. If the belt slips, its full effectiveness is not used. And as we know, this particular part is the connecting link between the generator and the battery, which transfers energy from one unit to another. In simple words, if the belt is not fully used, the battery charge drops.

If you suddenly hear an incomprehensible whistle coming from under the hood of your vehicle, you should know that water has gotten onto the stretched alternator belt. This means that you need to replace it and tighten it well. To do this, you will need a 17mm ratchet wrench and a 19mm socket wrench.

How to tighten the VAZ 2121 alternator belt

1. Open the hood and unscrew the nut that secures the generator and tensioner plate.

2. Do not loosen the fastening nut too much.

3. Now you can tighten the belt. This is done like this: grab the tensioner nut with your hand and move the generator down. If you move it up, the belt, on the contrary, will loosen.

4. When the correct position is found, tighten the tensioner nut. 5. Tighten the bottom bolt and start the engine. If you hear extraneous noises or see that the belt is slipping, you need to repeat the procedure.

6. Testing must be carried out with the maximum number of electrical appliances turned on. 7. If in this case the battery produces at least 13 Volts, then everything is done correctly.

Many drivers overdo it and tighten the belt too much, forgetting that this can lead to bad consequences. Among them are belt stretching and, as a result, slippage and bearing wear.

Pay close attention to your car and pay attention to extraneous sounds. Let's remember that in the previous article we talked about
