On the VAZ "classic" the installation of power steering is not provided from the factory. However, the owners of these cars experience certain inconveniences in driving at low speeds due to the tight rotation of the steering wheel. To make control easier and more comfortable, you can install an electromechanical amplifier on the VAZ 2107.

Electric power steering VAZ 2107 - is it needed?
Whether to equip your “Seven” with electric power steering (EPS) or not depends only on your personal wishes and capabilities. To decide and understand whether there is really a need to install this mechanism, you need to consider the positive and negative aspects of this type of modification, and then draw the appropriate conclusions.
The main advantages of introducing electric power steering include:
- reliability, efficiency, compactness, which is ensured due to the lack of hydraulics;
- easier, more convenient and safer driving, especially for women and the elderly;
- easy installation;
- Possibility of installation on any classic Zhiguli model;
- no additional maintenance is required during operation.
Electric power steering provides more comfortable and easier driving
The installation of an electric power steering system can be classified as tuning, i.e. improving the initial characteristics of the car.
The disadvantages include:
- material costs;
- expensive repairs;
- the need to install a more powerful generator on the car (from 100 A).
A powerful generator is required due to the fact that the EUR engine alone consumes about 50 A. Therefore, if you have extra funds and a desire to improve car control, then why not do it. In addition, installing an electromechanical power steering is noticeably cheaper than a hydraulic booster.
The introduction of a hydraulic booster on a VAZ 2107 is a complex and expensive procedure that requires the use of additional components and major modifications to the steering.
Purpose and principle of operation of the device
Partial dismantling of the torpedo for installation of the power steering
Before starting this work, you should find out the principle of operation of the EUR. Power steering is an important element in driving any car. Its task is to create additional forces when turning the steering wheel due to the presence of an electric drive. Modern cars have electric power steering.
Its main advantages for auto mechanics include:
- convenient adjustment of technical control characteristics,
- presence of high information content,
- reliability,
- significant savings in fuel used.
It should be noted that the EUR has 2 schemes: transmitting the forces of the electric motor to the steering shaft or the steering wheel rack. Auto mechanics distinguish 2 systems of such an amplifier.
- With 2 gears presented as a single unit, which integrates the steering structure and power steering. The last element contains an asynchronous type electric motor. The rack is equipped with 2 sections of teeth, one of which is considered the amplifier drive.
- With parallel drive - transmits forces from the electric motor to the steering structure through a belt drive. In this case, the force is simultaneously transmitted to the steering wheel rack and to the shaft.

Operating principle of an electric amplifier
Before considering the installation of electric power steering (EPS) on the “seven”, it is necessary to understand what this mechanism is. The main elements of the node are:
- electric motor;
- mechanical transmission gear;
- steering wheel sensor;
- steering torque sensor;
- control unit (CU).
The control unit receives signals about the speed at which the car is moving and the crankshaft rotation speed synchronously with the rotation of the steering wheel. The control unit calculates the magnitude and polarity of the power supplied to the electric motor. Additional force is created from the electric motor through a mechanical gear transmission, which makes it easier to control the front wheels. The force can be applied to both the steering shaft and the steering rack, which depends on the class of the car and the specific design of the electric booster. Since we are talking about classic Zhiguli cars, no steering rack was installed on these models.
Design of the electromechanical power steering: 1-electric motor; 2-worm; 3-worm wheel; 4-sliding clutch; 5-potentiometer; 6-casing; 7-steering shaft; 8-connector for torque sensor on the steering shaft; 9-motor power connector
The design of the EUR for passenger cars has small dimensions and is mounted directly on the steering column. The mechanism is located inside the car, which protects it from moisture, dirt and dust and extends its service life. The electric power steering has two main operating modes, which depend on the speed of the vehicle:
- When driving at low speeds, the device applies the greatest force to the steering mechanism to make driving easier. Thus, the steering wheel becomes “light”, which allows you to rotate it with the finger of one hand.
- When moving at high speeds, the steering wheel becomes heavier, which creates the effect of the wheels returning to the middle position. This operating principle increases traffic safety.
Electric amplifier delivery set
The electric amplifier is not too difficult to install, since its design and operating principle are quite simple. There is an opinion that Nivov and Priora electric amplifiers are quite unreliable and you can expect failures and jamming from them, and this, as you might guess, is not very good, especially at high speed. Therefore, we will consider purchasing a kit for installation on a classic, which, judging by the reviews, works stably.
Package Included:
- steering shaft casing;
- egnition lock;
- switches;
- pulse speed sensor;
- carburetor starter cable;
- device fastening elements;
- electronic control unit;
- electric amplifier assembly.
In addition, it will be necessary to replace the steering gear. It is necessary to install a short-shaft, but the bipod must remain original.
Which EUR to install on a VAZ 2107
The VAZ Seven can be equipped with one of two options for electric power steering:
- from Niva;
- special kit.
In the first case, purchasing the mechanism will cost 20 thousand rubles. In the second, the device is suitable for installation on any classic Zhiguli and costs about the same money. The VAZ 2107 can be equipped with both mechanisms. However, there are complaints about electric boosters from Niva: some car owners complain about their unexpected failure, which is dangerous while driving, since control becomes impossible. As for, there are no complaints about them.
On the VAZ 2107 you can install an electric booster from the Niva or purchase a kit for the “classics”
Basic Installation Recommendations
Initially, an adapter plate and a cardan are made. For this, a cardan from front-wheel drive and classics is used. Next, the crosspiece is dismantled (a thread is cut on it) and the cardan is adjusted to the length. After scalding the joint, the crosspiece is assembled. New grease will need to be added to its bearings.
Then the steering wheel is inserted (you can take it from a Lada Kalina). The next step is to connect the electrical part of the EUR. The red wire to the battery is connected through the fuse. The brown one connects to any mounting pin of this mechanism. The orange wire (ignition) is connected to the blue (ignition switch) through a fuse. The tachometer cables are connected to the dashboard chip to the blue-brown wire. The gray cable from the speed sensor is connected to the wire running from its 2 to 9 pin of the ECU.
Many auto mechanics do not recommend installing such a unit on the 2107 with their own hands. Especially if we are talking about a converted mechanism. As for the price factor, this pleasure will cost car owners a tidy sum of money. If the car is driven by a woman, then installing power steering is necessary.
Some VAZ 2107 drivers decide to install power steering on their car. This pleasure will cost them 5-6 thousand rubles. more expensive than installing an electric booster system. However, the workflow will take longer due to upcoming rework.
In order to make life easier for the driver, having the ability to rotate the steering wheel “with one finger”, confidently park the car without breaking his hands at low speeds and speeds, power steering has long existed throughout the civilized world, which can be installed on a VAZ without much pain “ classics."
Passing technical inspection and certificates
Before installing the ESD on your G7, you should think about passing a technical inspection. The fact is that installing such a device means making changes to the design of the vehicle, which will result in difficulties when passing maintenance in the absence of appropriate certificates. To avoid any problems, it is necessary to install the product in a certified VAZ car service center. In addition, you need to obtain the appropriate documents: a certificate from the manufacturer and the service where the installation was carried out. If you have all the necessary papers, then you can pass the technical inspection without any nuances. If conflict situations arise, the inspection station staff must request a written refusal indicating the reasons.
To pass technical inspection on a car with an electric power steering system, the installation of which is not provided from the factory, you will need an appropriate certificate
Despite the apparent complexity of such a device as electric power steering, its installation and connection will not take much effort and time. You need to prepare a mechanism kit with the necessary tools, and then follow the step-by-step instructions according to which you can install and connect the device.
WHAT ARE THERE ARE STEERING WHEEL TORQUE AMPLIFIERS (Simply STEERING WHEEL)?
Statistics show that almost no one buys a new VAZ 2107 to immediately install power steering. If you have money, they take a foreign car. So the amplifier is often installed on a used car. And it’s unlikely that anyone will want to invest about half the cost (about 31-32 thousand rubles in 2014 prices) into a VAZ 2107 worth 50-60 thousand rubles. Therefore, we will tell you in more detail about the more popular option - the electromechanical amplifier (EMA). It is a little cheaper, its cost is about 20 thousand rubles.
Electric power steering is provided for the VAZ 21214, but it is quite suitable for the entire range of classics, including the VAZ 2107. It is attached instead of a regular steering column.
The principle of operation is the creation of additional torque by the electric motor, acting synergistically and synchronously with the driver’s hands. The steering wheel gain is 5.7. This means that the turning effort, in which the driver “put in” 20 kg of his own force, now requires 3.5 kg.
What is included?
How does electric power steering work?
The operating principle is complex, using feedback:
The presence of a speed sensor leads to the fact that the faster the car moves, the “weaker” the force, that is, the steering wheel becomes “heavier”. At the same time, the electric motor turns on only when needed, and then you can hear it hum slightly.
The EUR starts working on the VAZ 2107 4-6 seconds after the ignition is turned on.
If any problems occur in the power circuit, the electronics will simply turn off the power steering, the warning light will come on, and the car will return to manual control.
Installation of EUR. For this:
The whole work takes about 2-3 hours. In order to install the device, almost all work is carried out in the salon.
The product warranty is 1 year from the date of purchase.
In general, if you are selflessly devoted to the VAZ 2107, then you can install electric power steering.
Another option: EUR from Priora. To install on a classic series, a special adapter plate and a special cardan are required.
Attention! Since during any maintenance the play of the steering wheel is measured, there is a 100% risk of “running into” a question and there is a high possibility that you will be refused an inspection with a “tuned” steering system.
If you want to pass MOT honestly, then you need to:
A little history
The first electric amplifiers were produced in Japan by the famous automaker Toyota. This happened in 1990, which is already quite distant for us.
Only 12 years later, in 2002, domestic engineers from Novosibirsk University began developing a Russian electric amplifier. After the completion of the project, the unit was refined and tested for several years at the AvtoVAZ plant.
New device
The engineers' task was to create a worthy analogue to foreign amplifiers, to provide the unit with the necessary advantages, durability and reliability. At the same time, unlike imported analogues, our electric amplifiers were much cheaper.
Today, these devices are produced by the Berdsk Electromechanical Plant, located in Russia and a subsidiary of AvtoVAZ.
Main advantages of the first ES
The electric amplifier would not be so in demand and popular without the obvious advantages that it brought along with its appearance. The strengths of this steering system include:
- The unit operates even when the power unit is turned off;
- The unit allows partial fuel savings, which has a positive effect on fuel consumption;
- Handling is improved in all components;
- Reliability of maneuvers at the highest level;
- Excellent safety record with regular use.
Why not hydraulic?
There are two types of power steering:
When the hydraulic power steering operates, high oil pressure is created in the system. The design of the hydraulic booster consists of supply pipes, a pump, a special reservoir and working fluid. The pump creates oil pressure, which affects the entire mechanism, making it much easier to turn the wheels.
Therefore, turning the steering wheel will be much easier. In general, the design of a hydraulic booster is very complex, installation takes a long time, and all mechanisms need to be regularly maintained. Only in this case will the hydraulic booster work perfectly.
If the car does not have a hydraulic booster installed, it is very difficult to install it. You will have to purchase additional parts, as well as make very serious changes to the steering mechanism. It is for this reason that it is not advisable to install a hydraulic booster on the “seven”.
Steering tuning
Tuning the VAZ-2107 steering can begin with a well-founded decision to replace the factory steering wheel with a sportier device with a diameter of 320 mm. Such a unit will give the car owner many advantages: firstly, he will be able to park with greater maneuverability. When upgrading the steering wheel, do not forget about installing a safety glass.
Those motorists who prefer sports tuning (low-number rack) should be prepared to pay twice as much money for the unit than for a simple standard device. However, after installation, the car will be able to turn the wheels in just two steering turns.
The third step to improve the car could be adjusting the camber and toe. Experts who have been working with different VAZ models for many years increase toe-in and negative camber on the front axle. At the same time, it is imperative to pay attention to the toe-in of the rear wheelbase, which should, on the contrary, decrease.
Operating principle
The electromechanical amplifier serves to reduce the efforts made by the driver. Plus, the device allows you to actively return the wheels and steering wheel to their original position after performing a maneuver. That is, the power steering system returns the car to straight-line motion faster, which has a positive effect on safety.
The ECU is a modular design built into the steering column. The module itself includes two main components:
- Electrical unit of synchronous nature;
- Controller.
It is important for VAZ 2110 owners to install such a system if they want to use wide wheels that differ from the factory ones by several sizes. And in general, if you want to feel real comfort and enjoy driving, and not turn the steering wheel with all your might, install an electric booster. He will react to even the slightest touch.
Complete with steering wheel
Although this is against the rules, now you no longer have to hold the steering rim with both hands. The car will become more than obedient and controllable when moving with one hand.
Numerous tests have shown that cars with powertrain are safer on the roads.
Technical specifications
When installing the EU on your VAZ 2110, it is important to take into account its technical characteristics. The node has certain requirements in this regard. Therefore, for the “ten” you should choose a device that corresponds to the parameters specified in the table.
| Parameter | Index |
| Maximum torque compensation | 35 Nm |
| Amount of current consumed (at Mmax 35 Nm and steering wheel rotation speed of 360 degrees in 1 sec) | 50 A |
| Operating temperature range | from -40 to +85 degrees Celsius |
| Unit weight | 9.5 kilograms |
| Electronically controlled motor | Inductor reactive |
| Direction of rotation | Reversible |
| Number of phases | 3 |
| Worm gear | With three passes |
| Worm shaft | Made from 40X steel |
| Worm wheel | Made from carbon fiber grade UPA 6/30-2 |
After familiarizing yourself with the specified parameters, you can choose the electric booster that suits your car. Do not forget that this is an electrical unit, so you should work with it very carefully.
Installation benefits
If you decide to install a modern electric booster on your VAZ 2110, you need to find out in advance what benefits you will receive from such manipulation. This will further convince you of the correctness of the decision.
- Installation does not require extensive experience or knowledge. Do it yourself in a few hours of work.
- The unit requires a small amount of electricity to operate. This will not negatively affect the condition of the battery or other components of the car.
- EU has no negative impact on the environmental friendliness of exhaust.
- Positively affects parametric indicators.
- Does not require complex and regular maintenance during operation. Install it and enjoy the comfort.
- Under low-temperature conditions, the electric booster works better than the hydraulic booster.
Some people believe that the operation of the electric booster is slightly weaker compared to the hydraulic booster. But in practice and on our roads you will not feel this. Therefore, this only drawback is more than controversial.
Equipment
Without modifications, you can install the Priora’s electric power steering on the “seven”. Products manufactured by are used with the same success. Device contents:
- Directly electric amplifier.
- Intermediate cardan shaft.
- Fasteners.
- Wiring.
- Brackets for fastening the electric power steering on the steering wheel of the “seven”.
- Decorative plait.
When purchasing, be sure to check the equipment included with the device. If some item is not in the box, you must immediately inform the seller about it. Otherwise, problems will arise during installation.
Stages of work execution
Due to the lack of power steering on the car, many car owners decide to install power steering on the VAZ 2107 with their own hands. Auto mechanics believe that the EUR of a Priora or Niva often fails. In some cases, the steering wheel jams. Such problems are dangerous when the machine is moving. Therefore, it is recommended to give preference to factory electric amplifiers.
In any case, you will need to adjust the gearbox speed sensor. Otherwise, when starting the VAZ and driving at low speeds, the driver will not be able to notice any changes. Thus, it will be difficult to turn the steering wheel. When accelerating at high speed, the steering wheel will yield to the car owner with little resistance.
If there is no speed sensor, you will have to install one. It must have a 6-pulse pass-through from the Niva 214. As a rule, this is included in the factory equipment. Other design changes that will need to be made include:
The ESD kit for the “Seven” includes the following elements.
