How to remove the speedometer drive of a VAZ 2107

Replacing the speedometer drive

We carry out the work on an inspection ditch or a lift.

We install the new drive in the reverse order of removal.

To replace the flexible shaft, disconnect the upper fastening of the drive cable from the speedometer (see Removing the instrument panel) and remove it from the hole in the front body panel.

Is it necessary to check the oil level in the steering gear housing of the “classic” and, if so, how to do it?

Actually, you don't need to do this. But if a leak is detected or there are any other reasons for doubt, the amount of oil in the crankcase is easy to check. Its level should be under the lower cut of the filler plug.

Does it make sense to use bearings in swingarms?

Certainly! Bearings (in this case, sealed ones are used) instead of nylon bushings, albeit slightly, do reduce the effort required to turn the steering wheel. At the same time, the rigidity of the trapezoid increases slightly, which has a positive effect on the stability and controllability of the car. The plant used this design on the new Niva VAZ-2123.

On the VAZ-21074, first and reverse gears are difficult to engage from time to time. It is sometimes impossible to even turn them off when the engine is not running and the car is stationary - only when moving. Replacing the clutch didn't help.

Most likely the cause is the transmission input shaft front bearing, which is mounted at the rear end of the engine crankshaft. It is possible that the bearing jamming creates the effect of a partially disengaged clutch and makes it difficult to shift gears, including if the engine is not running and the car is stationary. This is especially noticeable when using the lowest gears - reverse and first, when the rotational resistance is maximum.

Are there rear suspension springs for the VAZ-2115 sedan? If you believe the catalog, then VAZ-2108-2912712 springs are installed on it. But could it be that the VAZ-21099 weighing 940 kg has original springs, but the “fifteenth” weighing 985 kg does not?

In stores and on the market they often offer supposedly “ninety-ninth” rear springs. This is either a deception or a delusion. According to the documentation, all Samaras (from 2108 to 2115) have only “eighth” springs in the rear suspension. There are two options: the first, “high” - for the domestic market and “low” - for export. Each option is divided into two classes - A (“hard”) and B (“soft”). All springs are painted white, and differ in the color of the applied marks. For Russia: class A - yellow mark, class B - green. For export, respectively, A is brown, B is blue.

After replacing the transfer case on a VAZ-21213 Niva (due to loud noise), the speedometer began to underestimate the speed and mileage.

This information is not enough to accurately answer your question. There may be several probable reasons, for example the following.

1. The new transfer case has a speedometer drive with an inappropriate gear ratio.

2. Simultaneously with the transfer case, the main pairs of the front and rear axles were replaced, changing the gear ratio.

3. Wheels and tires were replaced with others of non-standard sizes.

After installing the 2107 gearbox on the VAZ-21013, the speedometer began to significantly increase the speed - for example, showing 120 km/h instead of 100. How can this be explained?

Now the plant produces gearboxes for “classics” only with a number of gear ratios 2105. But since different models of rear-wheel drive “Lada” have different main pairs of gearboxes, each option has its own modification of the box, which differs in the gear ratio of the speedometer drive and its gear mounted on the secondary shaft (an exception for the Niva, where the speedometer drive is placed in the transfer case). Gearboxes supplied for spare parts are marked with a felt-tip pen: a number is written on the top of the clutch housing, which is highlighted in the table (see) in bold. In addition, you can clarify the modification using a colored mark on the speedometer drive housing.

Replacing the speedometer drive

But at first I just thought that the drive was faulty, I counted the teeth (luckily only the middle was ground down), there were 13 of them, as in principle on all cars of this model with a five-speed gearbox, I bought a new one and installed it.

Imagine the surprise when, after a couple of kilometers, the speedometer failed again. Having removed the drive again and contrived, he looked into the hole in the box, while turning the shaft. It turned out that there was a problem.

I’ll write about how to change the speedometer drive drive gear in another article, but for now about replacing the drive.

Installation of the VAZ-2107 speedometer drive

Before installation, you must remove the cable from the braid and treat it with Litol lubricant, and then insert it back. Then you need to fix the guide wire to the drive fastening nut and pull it from below the car into the interior.

The following steps are carried out in the reverse order of removing the speedometer cable.

Combating speedometer breakdowns on VAZ 2106, 2107 and 2108: how to change the drive and cable?

A broken speed indicator does not allow the driver to track how fast the car is moving, which can lead to a tragedy or a fine being issued for violating the high-speed limit. The cause of the breakdown may be the speedometer drive of the VAZ 2107, or a broken cable. The article describes the speedometer, its structure, and the causes of the malfunction. Annotation on repair and replacement of the drive is also given.

Types of drives

When purchasing a drive, you still need to be careful. It is advisable to first remove the drive and count the teeth, since their number varies. There are several types of them: 9, 12 and 13 teeth. The installation of one or another drive depends on the installed rear axle, since they have different gear ratios. The 13 teeth are color coded blue.

If you are one hundred percent sure that the drive is faulty, then buy it. But I still recommend that you first figure out the reason why the speedometer is not working and only then make a purchase.

Note

Now there are still enough fakes on the market, and in order not to buy a low-quality part, check it at least a little. To do this, grab the gear on one side and the output on the other and try to turn it. If the engagement slips, it is better to refrain from such a purchase.

About the speedometer drive on the VAZ 2107 and its replacement

In order for the driver to be able to control the speed of the vehicle, the design of the instrument panel includes a speedometer , or speed indicator. Few people think about how it works until it malfunctions. The drive mechanism is responsible for its operation, for which the VAZ 2107 uses a cable. This cable on the VAZ 2107 is far from eternal, so if a malfunction occurs, it will need to be replaced.

How to check the mechanism for functionality

After changing the cable yourself, you need to make sure that everything was done correctly. To do this, you need to carry out a visual check and make sure that the cable is not damaged anywhere and is not bent. Only after this can you start the engine and check the serviceability of the device. The correct operation is checked by driving the vehicle.

4. The tip of the flexible shaft or the mating socket on the speedometer is damaged. In this case, you should change the VAZ 2107 speedometer cable or the speedometer itself
5. The flexible shaft drive is faulty or the speedometer drive socket in the gearbox is damaged. This is a rare breakdown, the elimination of which involves repairing the gearbox and is worthy of description in a separate article.

The VAZ 2107 speedometer drive can make noise for two reasons:

1. The drive is laid with small bending radii. To fix the problem, you need to re-route the speedometer cable, having previously lubricated it.
2. The braiding of the VAZ 2107 speedometer cable is damaged. In this case, the flexible speedometer drive assembly needs to be replaced.

As practice shows, most malfunctions are related specifically to the VAZ 2107 speedometer cable and can be eliminated by replacing it.

Removing the speed indicator cable on the seven

A step-by-step summary of how to replace the speedometer cable on a VAZ 2107 is as follows:

• Place the vehicle on the inspection hole and remove the negative terminal from the battery.
• To get to the flexible drive mount where it is connected to the speedometer, it will be useful to remove the device panel.
• Find the connection of the device to the speedometer and unscrew the fastening nut of the element.
• Then tie an iron wire to the device, which will tighten instead of the cable when it is pulled down.
• Move into the inspection hole and find the point of attachment of the device to the gearbox.
• Using pliers, unscrew the fastening nut, and then slowly dismantle the flexible element.
• You need to pull the cable from below so that the iron wire is pulled into its place.
• Once the device is removed, you will have the end of the wire in your hands. You need to disconnect it, and then proceed to install a new device.

If you do everything according to the instructions, then you won’t have to suffer through inserting a new cable into its location. The cable should only be pulled from bottom to top, but not opposite. This is due to the fact that the tip in the area of ​​connection to the gearbox has thickenings, so the cable simply will not pull out of the passenger compartment.

Tools for replacing the VAZ 2107 speedometer drive

To change the speed indicator drive of the seven, a small set of tools will be useful, also half an hour of time. The only tools you need are a screwdriver and pliers. To simplify the replacement work, it is recommended to use metal wire, the diameter of which should be between 0.3 and 0.5 mm. An indispensable condition for the wire is its length, which is more than 2 meters.

It is better to carry out replacement work from the inspection hole, because the cable mount in the gearbox is located in the lower part of the car. The replacement process is not difficult, so it’s enough to do everything once in compliance with the instructions, so that during the subsequent replacement you can carry out the work without the help of others.

This is interesting! The question often arises: how many teeth does the speedometer drive gear have? It is important to take this into account, because if you install a gear with an inappropriate number of teeth, the indicator will show incorrect information about speed and mileage. The number of teeth on the drive gear of the flexible speedometer drive is 13. This must be taken into account if the tip in the gearbox is changed.

Installing the cable

The installation process is similar to the principle of dismantling, and is done in reverse order. First, experts advise removing the iron core and lubricating it with Litol. This will increase the service life of the device. After these manipulations, the wire is installed back, secured to the wire at the bottom of the car, and tightened into the interior.

How to replace the speedometer drive?

In order to replace the speedometer drive on a “classic”, you will need several wrenches (10, 13) and a lift or inspection ditch.

The sequence of operations for replacing the drive is given below. Each number in the image corresponds to a step in the list. The work is performed sequentially and takes about 20 minutes.

1. Using a 13mm wrench, unscrew the bolt of the clamp securing the exhaust pipe of the muffler to the gearbox.

Unscrew the nut securing the flexible shaft of the speedometer drive.

2. Using a 10mm wrench, unscrew the drive fastening nut.
3. Using a 13mm wrench, unscrew the two nuts securing the cross member to the body. Then we lower the rear of the transmission down so that the studs come out of the crossmember holes.
4. We shift the gearbox to the right and remove the speedometer drive from the hole in the crankcase.

We install the new drive in the reverse order of removal.

To replace the flexible shaft (cable), disconnect the upper fastening of the drive cable from the speedometer and remove it from the hole in the front body panel.

What is the difference between the speedometer drive of the VAZ 2101, 2103, 2106?

Depending on the gear ratio of the rear axle gearbox, speedometer drives can be of three types. They differ in the number of driven gear teeth (12, 9, 13).

One of the rarest, almost “extinct” on the auto parts market is the 2101 drive without a mark with 12 teeth. It is suitable for Zhiguli gearboxes with a rear axle 2101, which has a gear ratio of 4.3. The VAZ 2102 station wagon (gearbox - 4.44) is also installed on older models, but has a larger reading error (“overestimates”).

Drive 2103 (9 teeth) is marked with red paint - for a gearbox with a rear axle 2103 with a gear ratio of 4.1.

The most popular option nowadays is the VAZ 2106 drive with 13 teeth, which has a blue mark on the body. Suitable for classic VAZ car models with axle 2106 (main gear ratio - 3.9).
