Gur for VAZ 2107 injector

EPS or electric power steering is installed on many modern cars today. This device allows for more comfortable and convenient driving. Accordingly, many car owners whose cars are not equipped with this system decide to install the unit themselves. From this material you will learn how to install electric power steering on a VAZ 2107 and what is the average cost of such a system.

Types of power steering

If you decide to equip your car with an amplifier, then you have several options - expensive and cheaper:

Power steering for the VAZ 2107 is a more expensive option. Such a system consists of a pump, supply lines, a pipe and a reservoir for working fluid. In this case, the working fluid is oil, which is under pressure in the system. The installation procedure is quite complex, like the design of the system itself, and the car owner will also have to periodically maintain the system. As practice and prices on the automotive market show, there is no point in installing such a unit, since its cost is almost half the price of a used 2107.
A cheaper and more suitable option for the “seven” is an electric booster. In practice, this unit allows you to cope well with the load placed on it, especially since its installation is simpler. In fact, the electric power steering works on the “seven” almost as efficiently as the hydraulic booster. It should be noted that the main advantage of such a system is the absence of the need for regular maintenance. The EUR on a VAZ is connected to the on-board network, since its operation requires 12-volt voltage.

"Seven" electric amplifier removed

Detailed guide to installing electric power steering

Buying an electric amplifier today is not a problem; all you have to do is go to any specialized store. The design features of the “seven” allow the installation of an electric amplifier from the Lada Priora. But before you purchase this unit, you need to take into account that for installation you will need to make or additionally buy a cardan, as well as an adapter plate. We will not describe the entire process in detail, because if you understand what we are talking about, then the instructions below will be enough for the correct and complete installation of the system (the author of the video is the Anton Mariyan channel).

If you are faced with the need for installation for the first time, then it would be better to seek help in this matter from qualified specialists. After all, if you make mistakes, getting rid of malfunctions can be problematic, so if you lack experience, it is better to immediately entrust this matter to professionals.

So, here's how the installation procedure works:

First, you should completely de-energize the on-board network to prevent a possible short circuit during repair work. To do this, simply open the hood and disconnect the terminals from the battery.
Next, you will need to remove the protective cover from the steering wheel. To do this, simply unscrew the bolts that secure the two parts of the cover.
At the next stage, the old steering cardan is removed, as well as the installation of a new part, which comes with the purchased system.
After completing these steps, you will need to use a drill to drill holes to fix the electric amplifier. Depending on the design features of the new EUR, the holes may be different, so at this stage you need to use the installation instructions that should come with the kit.
Once the holes are drilled, the electric amplifier must be fixed.
Next, the wires from the speed and speed sensors are connected. When connecting, be careful - you cannot allow the presence of bare wires in the electrical circuit, so all cables must be carefully insulated.
After completing these steps, the power circuit of the unit is connected; remember that the electrical circuit must include a safety element.
Actually, at this point the process of installing the electric booster system can be considered complete. All you have to do is reinstall the protective steering wheel pads and tighten all the bolts that were unscrewed earlier. Then the battery terminals are connected and the functionality of the system is checked. If problems arise with the operation of the electric amplifier, you need to check the correct installation and also make sure that you did not make mistakes when connecting the wires. As practice shows, one of the main reasons for the incorrect operation of the ESD is incorrect wiring.

Equipment set

When purchasing a power steering for a VAZ 2107, you need to check the availability of parts and components according to the list below:

power steering pump with pulley;
expansion tank;
gearbox with actuator;
hydraulic cylinder;
set of high pressure hoses and pipelines.

In addition to the equipment, it is necessary to purchase a special operating fluid for hydraulic systems. It is marked ATF; the use of substandard oils leads to rapid equipment failure.

You can see how the EUR installed on the “seven” works in the video below (the author of the video is Roman Patrikeev).

If you are the owner of a truly popular car, the VAZ 2107, then this article is just for you. In it we will look at how to add comfort and pleasure to driving this car.

Power steering on the VAZ 2107 is not included in the standard package; the manufacturer probably believes that the forces applied to the steering wheel are not so great to install it. And besides, this would undoubtedly increase the final cost of one of the most budget cars.

If you still want your steering wheel to rotate in place as easily as on foreign cars of the late 90s, then you need to think about installing power steering. Today there are several ways to solve this difficult problem.

You can choose a steering rack with a power steering system and consider installing it on a car, but in my opinion this is quite labor-intensive and energy-consuming. The easiest way is to purchase a ready-made kit for modifying a conventional steering rack installed on a car.

The kit includes a pump, pulley, special steering gear, hydraulic cylinder, expansion tank and a set of high-pressure hoses. Now let's move on to a description of the components and methods of their installation.

Upgrade options

Installing a certified power steering makes the steering more comfortable and suitable for women and older drivers. There are many of these among car owners who own one of the most common cars in our country - the “seven”. The effort on the steering wheel is clearly excessive for them, especially when maneuvering at low speed or turning the wheels in place.

Installing a set of additional equipment allows you to successfully solve this problem. You can purchase mechanisms in retail stores or online. When purchasing, it is important to make sure that the proposed kit has a technical passport certified by the wet seal of the manufacturer. In addition, a special certificate is required; all the documents listed above are necessary to make changes to the PTS,

Design of rear brake cylinders for VAZ 2101, 2102, 2103, 2106, 2121 cars

The brake system of VAZ 2101, 2102, 2103, 2106, 2121 cars is hydraulic.
In the brake mechanisms of the rear wheels, its working elements are brake cylinders, which move the brake pads with their pistons. Diagram of the brake cylinder of the rear brake mechanism of VAZ 2101, 2102, 2103, 2106, 2121 cars without a mechanism for automatically adjusting the gap between the brake pads and the drum.

Rear brake wheel cylinder devices for VAZ 2101, 2102, 2103, 2106, 2121 cars

The device of the brake cylinder of the rear brakes of VAZ 2101, 2102, 2103, 2106, 2121

The brake cylinder is secured with two bolts to the support plate in its upper part.

It has a fitting for bleeding the hydraulic brake system. The tip of the brake pipe supplying the brake fluid is screwed into it.

Pistons with pad stops pressed into them are installed on both sides of the cylinder.

Rubber sealing rings are pressed to the back of the pistons using a spring and support cups.

Protective rubber caps (boots) are installed on the outside of the brake cylinder. They protect its internal cavity from contamination.

Notes and additions

— The rear brake cylinders of VAZ 2101, 2102, 2103, 2106, 2121, unlike the cylinders for VAZ 2104, 2105, 2107, do not have a built-in mechanism for automatically adjusting the gap between the pads and the drum. This automatic adjustment mechanism is made separately on each brake pad. This must be taken into account when replacing cylinders and repairing them.

Removing the outer CV joint of a VAZ 2109

All work can be carried out without an inspection hole or overpass; all you need is a good jack and supports. The disassembly procedure is as follows:

Place stands under the rear wheels.
Remove the cap from the front wheel.
Unlock the nut using a sharp chisel and hammer.
Using a 30" socket and a long lever, rip off the nut.
Remove the four bolts securing the wheels to the hub.
Place a jack under the side to be repaired and lift it up.
Remove the wheel. It is advisable to install a support under the body.
Pull the cotter pin out of the tie rod end pin and unscrew the nut.
Using a puller, pull the pin out of the steering knuckle.
Unscrew the two ball joint mounting bolts. This will be easier than using a puller to knock the pin out of the hub.
The hub now “walks” freely on the stand. Personally, I knock out the inner CV joint using a small chisel and hammer. Literally 2-3 sharp and precise blows, as the drive comes out of the box. But be sure to drain 2/3 of the oil from the gearbox, otherwise you will lose it.
Knock the outer grenade out of the hub.

You don't have to remove the drive completely, but that's not very convenient. It is much more pleasant to work with grenades if they are accessible and can be clamped in a vice, rather than bending over under a machine. Before replacing the external grenade boot, assess the condition of the entire drive for damage or defects. After all, it may turn out that not a partial repair is required, but a complete one.

Rear brake cylinder replacement steps

But before you get to this part, you first need to knock down the rear drum and also remove the brake pads.

After this, you need to apply a penetrating lubricant to the back of the tube. Then unscrew it with a split wrench:

Then we unscrew the two bolts that secure the cylinder on the reverse side:

The most convenient way to do this is with a ratchet handle:

Then you can remove the cylinder from the other side, since there are no more fasteners:

If it is necessary to replace the rear brake cylinder, then we purchase a new part. And we install it in the reverse order of removal. The price of a new rear wheel brake cylinder for a VAZ 2106 and other Zhiguli models of the “classic family” is about 300 rubles apiece.

If you are conducting a complete audit of the system, it is better to replace both at the same time. Especially if they haven't changed for a long time. It is best to buy such spare parts only in trusted stores so that the likelihood of counterfeiting is minimized. Currently, most components for VAZ models are produced under the Lada Image brand. These are the spare parts that are installed on all cars at the factory, so there is no doubt about the quality of this brand.

If memory serves, many boxes and packaging with such components have an authentication system. That is, you can send an SMS message with the code that is printed on the packaging under the protective layer and find out whether you have an original or a fake. Also, a similar check can be performed through the official website of this company.

Introduction

The VAZ-2107, to which thousands of compatriots are accustomed, is inferior in several respects to its foreign counterparts, which is why motorists who want to improve the characteristics of their own car do their own tuning of the VAZ-2107 steering. A thoughtful and correct tuning solution can be considered the installation of a hydraulic booster or electric power steering. Thanks to competent modernization, a unit will appear in the car, through which additional force is created on the wheels when entering a turn. The improvements made will bring domestic cars closer to the class of more expensive foreign cars.
