Repair and replacement of VAZ 2107 car seats (injector)

Repair of front seat slides

VAZ front seat slides include the following parts:

Repair of seat mechanisms is carried out with the seats already removed. To restore the functionality of the mechanism, the following operations should be performed:

• clean from dirt;
• if necessary, replace worn or damaged parts;
• lubricate

Dismantling the slide is done as follows:

1. Remove the spring.
2. Remove the rod pin.
3. Unscrew the bolts securing the slide to the seat.
4. Remove the skids.
5. Remove the screw rod from the bracket.
6. Move the sliders along the guides.
7. Remove sliders and rollers.

After disassembly, you can inspect the parts to determine the cause of the breakdown. The lack of fixation of the seat back of the VAZ 2107 can be eliminated by replacing it (or replacing the comb or clamp). To do this, you will have to cut off the broken part with a grinder and weld a new one in its place. The upholstery of the chair must be protected from welding by covering it with a wet cloth. If possible, it is better to leave one frame of the chair before welding. At the same time, you can wash the seat upholstery.

Replacing seats

You can make the interior more comfortable by installing seats from another car model or special seats for auto tuning on the VAZ 2107. The latter are produced in various modifications, which allows you to choose a seat that suits the car owner.

You can install any car seats from foreign cars that are suitable in size in the VAZ interior. It should be noted that such a replacement requires welding to change the fastening design. During welding, it is necessary to protect the casing from sparks. If you don’t have a welding machine at your disposal, you will either have to be content with the available selection of car seats, or contact a specialist.

Rear seat repair

The backrest of the rear seat can be easily removed. To do this, you need to lift it slightly so that the staples are separated from the latches. To remove the saddle, you should grab it by one edge with both hands and pull it up strongly, this will ensure it moves away from the lock. Then the same is done with the other side, after which the repair can begin.

Fastening the front seats

Many owners of the VAZ 2107 model, which has already been discontinued, want to decorate the interior by installing seats from other car brands. This primarily applies to the front seats. In this case, you should pay attention to UNP products. Which seats are suitable for VAZ from the company’s catalog? Almost everything. You can choose anatomical seats, such as “Boxer”, “Racer”, “Sport”, etc. They are quite lightweight, since the frame is made of durable fiberglass, have a steel frame and a bucket shape with side supports, which increases the quality of driving. The seat backs often have reinforcing pads, and the headrest is integrated. The seats are thin due to fiberglass, which gives additional space to passengers sitting in the back.

Sports UNP seats are perfect for the VAZ 2107. They have maximum lateral support, a one-piece design, an integrated headrest, allow you to install sports belts (3-6 attachment points), additional pillows, including lumbar support. All UNP products can be easily integrated into any car due to the availability of installation adapters, which are sold along with the seats. In the case of the VAZ 2107, we are talking about the slide and side mounting brackets.

Installing a sports or anatomical car seat is not a cheap pleasure, so many car enthusiasts want to know whether seats from a foreign car will fit in a VAZ 2107. Experts believe that almost anything that fits the dimensions can be supplied if it is possible to carry out high-quality welding work. For example, in the “seven” you can try to put parts from Opel (Vectra A, Cadet) or from Skyline.

It should be borne in mind that the installation of non-original seats may raise questions from regulatory authorities, since such an operation is considered to be making changes to the design of the machine.

Which seats fit without modifications?

If there is a desire to change the seats in the cabin of the seven, then you need to install seats from a foreign car, which are characterized by increased comfort. In this case, a problem arises - the cost of seats from foreign cars is sometimes 2 times higher than the price of new seats for the seven. To reduce costs, you need to choose used models of chairs that will cost no more than new factory models.

To install new seats in the interior of the seven from a foreign car, the following factors must be taken into account:

1. Dimensions or dimensions of devices, which should not be much larger than standard ones. There are no problems with this, since seats from foreign cars are not only comfortable, but also often have small dimensions, that is, they are compact.
2. Mounting type. The brackets for the new seats, ideally, should fit the mountings in the cabin, so that they can be installed in the classic cabin without modifications. This factor plays an important role, since the fastening affects not only the possibility of placing seats in the VAZ 2107 interior, but also the safety of their operation. In most installation options, it is still necessary to make or select some spacers, washers or bushings in order to align the mounting points of the skid and the car body. But there is no need to weld or cut anything with a grinder.
3. Shape and type of cladding. These are secondary factors that affect the comfort and appearance of the cabin. Most models of seats from foreign cars have a quite presentable appearance, and their installation does not require the use of covers.

By installing or replacing VAZ 2107 seats with analogues from a foreign car, you can simultaneously obtain benefits such as increased comfort, as well as changing the interior design for the better. No matter what model of foreign car the seats in the seven are installed on, they will still look better than the standard ones. Taking into account the factors described above, it is necessary to figure out which car the seats for the seven are suitable for. Preference should be given to the following brands:

• The 1993 Toyota Corolla E100 is an ideal option, since the interior of the LADA 2107 fits not only front seats without any special modifications, but also a rear sofa. In addition, devices from a car of this year of manufacture will not cost exorbitantly, so you can buy them very cheaply at a disassembly site.
• The 1996 Mercedes W210 is another good option. Reviews from car owners who have installed Mercedes seats indicate a number of advantages - no need for modifications, comfort, improved interior design.
• Toyota RAV4 - you also don’t need to make any modifications, you just buy, change and enjoy.
• Ford Scorpio - devices from the Ford brand are distinguished by their presentability. By installing such seats, you can enjoy long trips in a domestic car.
• Audi A80 - can be made without major modifications. The result of the replacement is a high quality of comfort, a large number of controls and settings, as well as a change in the interior of the cabin.
• Mazda 6 - fits perfectly under the standard brackets of the classics.
• Ford Recardo - you can completely install both the front and rear seats on the VAZ 2107.

You can also install devices from car brands such as Skoda and Fiat. However, there are some features that need to be taken into account - this is a shift in the center of gravity. Having installed such chairs, you will need minor processing in the form of making a couple of holes, performing additional fastening. This will increase the stability and reliability of structures.

If desired, you can put seats in the seven from almost any modern car. And now their choice is huge. Such chairs can have all kinds of electrical adjustments, separate heating of the back and cushion, leather chairs can have ventilation, as well as a massage option.

There are a sufficient number of options without modifications, and which one is better to choose - it all depends on the finances, availability and desire of the car enthusiast. If you choose devices from Volkswagen, Nissan and Peugeot cars, then you cannot do without modifications. If you are sure that these brands have the best chairs, then if you wish, you can insert them into 2107, but you will have to modify the fastenings.

Installing a new seat

Let’s look at some of the nuances of installing foreign-made seats in “classics”. True, we will analyze only the most common problems. After all, each chair has its own requirements for installation and it will not be possible to describe all the options step by step in one article. Drivers usually face the following difficulties:

1. A common problem is the misalignment of the mounting slides. In this case, you will need to install the skids from the “original” car. To do this, you will need to drill additional holes for fastening in the bottom. Do not forget to carry out anti-corrosion treatment;
2. The simplest drawback is that the driver's seating position is too low. As a result, you cannot fully control the traffic situation. To avoid this problem, it is recommended to weld cross members into the bottom and install the seat slides on them;
3. Also, some drivers want to install an electric seat drive on the VAZ 2107. This approach allows them to be adjusted without effort. The process of installing an electric motor is not complicated. But, be sure to connect through a fuse. Moisture often accumulates on the floor of the car, which can lead to a short circuit.
