Niva speedometer drive repair

The speedometer cable on the Niva is attached at one end to the dashboard and the other to the transfer case, so replacing it will require a pit, overpass, or lift.

You can jack up the car on blocks of wood, which is what I did.

We start from the bottom, otherwise it will be impossible to pull out the dashboard (I unknowingly started from the top, but this is no longer in danger for you).

The speedometer cable cap can be unscrewed and removed manually, but if it gets stuck, you can use pliers, but without pressing hard.

All that remains is to cut the ties that attach the electric cable to the cable. connecting the speed sensor, and you can move to the top, since the cable is freed, and in fact, if you wish, you can pull it out into the cabin, but let’s wait for now.

In the cabin, we look under the steering column and unscrew the two screws that secure the dashboard trim

The cladding is fastened on top with metal clips, so that without self-tapping screws it is simply pulled out with force, after which the long plastic nuts of the bolts securing the panel itself are unscrewed, and the entire panel is pulled out.

If the panel does not want to be removed, then you need to tighten the cable from below, since only it can hold it.

This is done right in the salon. The cable in the cabin runs to the left of the stove, and that’s where you need to pull it up.

After this, the panel will be easily removed and the cable can be easily disconnected from the speedometer.

Now you can pull out the cable, but a small ambush awaits here. The rubber seal through which it passes is almost impossible to remove, so there is only one option left: break the top cap and pull out the cable from below. Then the elastic band will be easily squeezed out.

The old cable has been removed. Now we install the new one in reverse order. For a simple Niva, it has this look and size, and in the car market it is called long.

First, we push it into the interior from below, attach it to the speedometer, assemble the panel, attach it to the transfer case, adjust the sealing rubber from below and secure it to the cable with electrical ties. speed sensor connection.

In continuation of the previous post. So I installed a whole new steering wheel and almost started jumping for joy when I was informed that if the steering gearbox was from 213, then the pendulum had to be taken from it. (It’s all the fault of the modified bipod on the improved VAZ 21213) To tell the truth, when buying, I only looked at the length of the rod (since it’s short on the VAZ 21214) and was not at all familiar with the topic. So I had to and now I’m telling everyone who doesn’t know. The pendulum, of course, turned out to be 2121. But I had already assembled this config and started testing. Firstly, the wheels immediately moved apart in convergence in different directions (with the same thrust), secondly, the turning radius of the wheel to the left and to the right was different! I changed the pendulum to 213 and thought now everything would return to normal, but that was not the case. The turning radius leveled out and the toe remained to the sides. After which, with reluctance, I still went to the wheel alignment and the computer showed that I needed to unscrew the rods by 2 cm and there was nowhere else to go! And so the threads are a little bit. I started using the Internet further and there I found something interesting. It turns out that when the VAZ 21213 came out, the steering was changed, namely the bipod of the gearbox and pendulum, as well as the swing arm of the fist! This means that if you want to change the outdated design to 21213, then you will need steering knuckle levers, a pendulum and a bipod (all rods remain unchanged). The steering knuckle arms 21213–3001020 and 21213–3001031 are approximately 20 mm longer than the previous 2121. The pendulum lever 21213–3414084 and the bipod 21213–3401090 differ from similar parts 2121 in configuration and arm angle. With parts 21213, the force on the steering wheel will be reduced by approximately 20%. But at the same time a little maneuverability is lost. If you leave the old kit, then in case of repair you will have to buy and install all the specified parts with the initial index 2121. Important note: the named parts can only be replaced as a kit! Otherwise, the geometry of the trapezoid is violated, which is unacceptable. By the way, the steering knuckle lever 2123 is also different. It is shorter than 213, almost as long as 2121 (all because with the advent of power steering, special efforts are no longer needed and the design was returned to a more maneuverable one) I hope it was useful.

I had to change the cable because it was rubbing against the front universal joint and the sheath was worn out.

There are three different cables for the Niva, the store gave me a short one, it turned out that it was from a VAZ-2121 (that is, from the old one! Its length is L = 1180 mm, model GV 307D). I needed it from a VAZ-21213 (also 21214 is coming! GV 307-11 and its length L=1350 and up to 1420 mm). It also comes from the VAZ-2131, it is shorter, L=1300 mm and the GV 307-08 model. I handed in the short one and asked to bring the long one, I waited a week.

Why the speedometer may not work on a Niva 2121 car

The Niva car or VAZ-2121 is one of the most successful developments of domestic engineers. Having begun mass production in 1977, the car was in demand not only in the USSR, and then in Russia, but also abroad. In some countries, fan clubs of this model have even been created. The first Nivas were equipped with a three-door body and a carburetor engine with an output of 80 hp.

They rolled off the assembly line with virtually no changes in design and technical characteristics until 1993. In 1994, car enthusiasts saw a modified body and an 82.8-horsepower engine. The car was named VAZ-21213 Niva. Then the Niva VAZ-21214 appeared, on which, starting in 2002, injection power units began to be installed. In 2006, the name Niva officially ceased to exist. The car, until 2022, was called “LADA 4×4”, and now it is “Lada Niva Legend”.

From the very moment of its creation, until today, the Lada-Niva has been distinguished by the extreme degree of reliability of all components and assemblies. It is not for nothing that a huge number of these cars continue to travel on roads and off-roads, despite the fact that they came off the assembly line several decades ago. But, which is quite natural, the older the car, the more breakdowns there are. Along with the transmission, engine and body, failures of motion control systems occur, which include the speed control system.

In the article we will look at the reasons why the speedometer on the Niva does not work, using the VAZ-21213 and VAZ-21214 as an example, since these cars are the most typical and widespread representatives of the family of Tolyatti SUVs. But first, briefly about the structure of the speedometer itself and the principle of its operation.

Elements of transfer case 2121

The multiplier is installed only on VAZ models with 2 drive axles. Located behind the gearbox. A driveshaft is mounted on the transfer case itself. Basic elements for the Niva transfer case, which are present in all models of Soviet-made demultiplicators:

frame;
intermediate and drive shafts;
set of bearings and gears;
satellites;
drive shafts of the front and rear axles;
oil seals, flanges, couplings;
differential;
control and control levers.

The connection between the unit and the Niva gearbox is rigid, which is carried out through a coupling and a shaft. The transfer case of the VAZ 21214 or Chevy Niva model differs from the classic one only in the presence of a speed sensor drive.

Speedometer

The basis of the speedometer design is:

speed sensor;
electronic control unit;
display.

The speed sensor receives indirect information about the speed of the vehicle, which is removed from the drive located in the transfer case. This is typical only for Niva. In other cars, the gear drive of the speedometer is installed on the output shaft of the box or on the drive of the front left wheel.

The sensor, converting the drive speed into electrical impulses (using the resulting Hall effect), transmits them to the electronic unit, which processes the signal and sends it to the display. The latter shows on its screen what the current speed of the car is. Data can be presented as numbers or a scale on digital displays, or indicated by a moving arrow pointing to the values on a graduated scale on analogue indicators.

For your information. The electronic unit, receiving and processing information, sends it not only to the speedometer display, but also to the fuel supply system. The higher the speed, the more fuel will flow into the engine. It is also interesting that the program contains an algorithm that prevents the electric power steering from operating when the speed sensor is faulty.

Why does the speedometer not work?

There may be several reasons why the speedometer on the Niva suddenly stopped working.

The malfunction may have occurred due to a broken speed sensor.
Secondly, the car wiring is damaged or the contact in the electrical circuit is broken.
The third reason, sometimes, is the speedometer needle getting stuck in a certain position.
A problem with the electronics of the control unit can also cause a speedometer malfunction.
Incorrect installation of speed control system parts after they have been replaced or removed.
