Read how to adjust the gear shift control drive on a VAZ 2110. A diagram of the device is presented.

If during operation of the car you have problems with gear shifting (there is no clear shift), then it’s time to adjust the drive that controls this mechanism. Also, this work must be carried out immediately after you have carried out its repair and reinstallation, since after such actions the entire gear shift mechanism “diverges.”

We did the setup on a VAZ 2110 car.

1. On the transmission control rod, it is necessary to loosen the nut of the clamp bolt; just unscrew the bolt 4–5 turns (you will need a 13 key). You can only get to it from underneath the car.

2. In order to ensure free movement of the rod relative to the gear selection rod, the grooves at the end of the rod and the clamp should be widened using a screwdriver. Then place the rod in the neutral position.

3. Next, we go into the car interior and remove the gearbox cover from the handle. You can simply lower it to the very bottom, and install the lever so that its lower (non-bent) end is approximately vertical.

If you have template 67.7834.9527, then set the gear shift knob as follows: with the lever cover removed, install the template in the trim window (number 14 in the diagram above) of the reverse locking bracket.

4. Under the bottom of the car, you need to carefully, without sudden movements of the hand, select the axial play of the rod in the rearward direction and its angular play in the counterclockwise direction (the task is not to move the gear shift lever).

5. Now you can tighten the nut of the clamp bolt under the car back, just adjust the clamp itself a little forward so that there is about 2-3 millimeters of free space between it and the rod.

For some reason, many car owners are inclined to believe that the design of such a complex mechanism in a car as a gearbox is not so complicated at all, and that they are quite capable of repairing the gearbox in their garage.

However, the initial view is quite often incorrect, because such a serious unit consists of several shafts, synchronizers, a bunch of gears (gears), which are interconnected in a strictly defined order, in one of the links leading to failure of the entire mechanism.

Why is gearbox adjustment needed?

But when performing a complete or selective transmission repair, correctly assembling such a complex unit during repair is only half the battle. No less important is the precise adjustment of the gearbox, on which, like any other fine-tuning and adjustment, the normal operation of the entire unit and the duration of this work depend. Insufficiently precise adjustment of the gearbox will manifest itself as an annoying hum when the car is moving, and most importantly, a significantly reduced resource of the unit. Failure to properly fine-tune the gearbox, and often (mostly during home-garage repairs) and simply the absence of any fine-tuning due to reluctance or simply inability to adjust the gearbox, can guarantee that such a gearbox lasts no more than 50,000 km.

What does it mean to adjust the gearbox?

Basically, in order to adjust the gearbox, you need to take care of setting the installation dimensions, which determine the relative position of the unit parts - for example, the distance from the differential axis to the end part of the drive gear or the installation of differential bearings, which must be mounted with a certain preload. Correct installation of the unit parts in compliance with the correct technological dimensions ensures an optimal contact area in the meshing of gears, eliminates excess stress, or, on the contrary, slack in the operation of the mechanism, which will ensure the absence of unnecessary noise and its normal operation.

Where is the best place to adjust the gearbox?

When installing parts, installation dimensions are set by selecting adjusting washers. Their thickness is calculated with an accuracy of hundredths of a millimeter, and to determine these dimensions, equipment is required with an accuracy of 0.001 mm. Therefore, the optimal option seems to be to contact a specialized car service with qualified personnel and, most importantly, the necessary equipment.

In addition, it happens that a breakdown that initially seemed significant, after undergoing pre-repair testing on special car service equipment, is “cured” only by debugging. And to fix the problem, it’s enough to adjust the gearbox, and sometimes you don’t even need to remove and install the gearbox, which can make contacting a service station even more profitable than doing it yourself, not to mention the guarantees.

Not all motorists have any idea what the name of this or that part in their car is. In this case, we are talking not only about the mechanisms “hidden” in the engine, but also about the devices with which they interact literally every day. One of these parts is the gearbox linkage.

Please note: The name "slide" is not official for this mechanism, but it is generally accepted. In fact, this part is called the transmission control rod.

What is a gearbox rocker?

Many drivers mistakenly believe that the rocker refers to the gear shift lever, but this is not entirely true. If we are talking about a gearbox rocker, we mean a composite mechanism whose task is to connect the gearshift lever and the rod. That is, the driver cannot see the backstage, much less touch it. This element is located between the lever and the gearbox itself, and it is located under the bottom of the car, near the driveshaft, and in some cases under the gearshift lever itself.

As can be understood from the description, the rocker regularly has to deal with serious loads, so this element must have good strength. Despite this, the slide is susceptible to damage. If it does not contain enough lubricating components, drops of water, dust or other “debris” have entered it, there is a high risk of part failure.

Please note: On some cars, the rocker can last 200-300 or even more than thousands of kilometers without replacement. But, if we take the average result, usually the gearbox linkage fails after 100 thousand kilometers of operation.

Signs of gearbox wear

The driver must pay attention to possible failure of vehicle components, including knowing the characteristic signs of wear on the gearbox linkage in order to take timely action to replace it. Despite the fact that the mechanism is quite reliable, you should be aware of the following “symptoms” of its imminent breakdown:

Drivers often ignore the appearance of play in the gearbox, believing that this is a normal situation. In fact, if backlash occurs, it is imperative to diagnose the gearbox, and, if necessary, adjust or replace the linkage. The fact is that a slight play is already a fairly serious symptom of a faulty gearbox linkage. If it “breaks” while the car is moving, this can lead to serious consequences for both the car and the driver, since in such a situation there is a high risk of getting into an accident. That is why, if you notice problems with gear shifting, be sure to contact a service center for diagnostics and repair of the linkage, if necessary.

Adjusting the gearbox rocker

It is not always necessary to completely or partially replace the scenes. Quite often you can limit yourself to simple adjustments. At the same time, it is possible to adjust the link with your own hands, without contacting a service center. There are two ways to adjust:

It is worth noting that the general processes for adjusting the gearbox rocker are described above. It is important to say that the process may differ depending on the car, so before starting work it is recommended that you read the instructions specifically for your car model.

The gearbox on the VAZ-2110 sometimes starts to act up. If you neglect the care and maintenance of this part of the car, you can get many problems with the operation of the gearbox. As a rule, these are inaccuracies in gear shifting, characteristic “knocking out” of the gear, crunching and clanging when manipulating the gearbox lever. Some car owners believe that all these symptoms indicate a gearbox failure.

In fact, most often the gearbox is in good condition, but the rocker may fail.

You can replace the unit with a new one, or you can get by with proper adjustment of the rocker. Adjusting this element will help troubleshoot problems and make sure that the problem is related specifically to the gearbox linkage. It happens that a car owner simply begins to change one component after another without understanding the problem, wasting money and time to no avail.

The gearbox gate itself is designed to speeds did not change spontaneously . It happens that due to incorrect or erroneous adjustments, the entire transmission system begins to work incorrectly and may even fail. Therefore, you need to be able to adjust the gearbox rocker with your own hands, especially since this procedure is not complicated.

When does the rocker need adjustment?

Gear shift mechanism.

1. After the transmission on the car has been replaced or removed.
2. When loosening the fixing clamps.
3. If the cardan was changed.
4. If the link starts to rotate on its hinge.

Although visually it may seem that the rocker is in place, even the slightest movement of the rocker can lead to incorrect operation of the gearbox. It happens that it is enough to tighten the link to the cardan by 1 mm, after which all functions of the gearbox will be restored.

Preparing to adjust the rocker

On an old car, it is better to lubricate the linkage attachment point with a penetrating compound in advance.

Before starting adjustment work, you need to prepare the place and carry out the following preparatory measures:

1. The car needs to be parked in a pit.
2. The handbrake must be tightened all the way.
3. It is mandatory to install wheel chocks.

For a faster and better adjustment process, it is better to perform all work with an assistant. The process itself can occur in several ways.

First adjustment method

To adjust, you need to loosen the clamp connecting the rocker drive to the cardan.

This method is the simplest. In this case, the gearbox linkage is adjusted according to the reverse speed. First of all, you need to loosen the clamp, after which the reverse gear is engaged. Then you need to position the lever in the position you need. After this, the clamp is tightened and the operation of the entire mechanism is checked.

If you don't succeed the first time, you need to listen for knocking and crackling noises when switching . They must either decrease or increase. In accordance with this, you need to position the lever in the desired direction. If all manipulations do not lead to the desired effect, you need to resort to another adjustment method.

Second adjustment method

The gear shift lever should rest against the locking plate (in the photo it is made of light plastic).

This method is used if the first one did not lead to the desired results. When using it, you can more clearly position the gearshift lever. This method is as follows:

It happens that some VAZ-2110 cars do not have a plastic limiter retainer, so the adjustment in this case is carried out not in first gear, but in neutral.

Third adjustment method

This method is quite complicated , since it involves calculating the depth of the gearbox linkage to the cardan. Due to this, the position of the lever in the neutral position can be accurately calculated and adjusted. It happens that if the calculation is not accurate enough, all manipulations only lead to the appearance of rattling when changing gears.

If adjustment by any of the above methods does not lead to the desired results, several options are possible to solve the problem:

1. Carry out diagnostics at a service station to make sure that the problem is in the gearbox linkage.
2. You can replace the gearbox linkage.
3. You can contact specialists who will adjust the slide themselves.

Why doesn't adjustment help?

It happens that, despite the adjustments, the rocker still rattles.

This problem can be solved by installing a special spring on the rocker. It will hold the lever, eliminating rattling.

The gearbox linkage, like everything else in a car, requires care and timely adjustment. A misadjusted gearbox linkage can cause discomfort while driving. For example, the gear knob may rattle, the gear shift may become inaccurate, the speeds may “knock out” from time to time, and the lever itself may begin to “play.”

To get rid of all this, you need to carry out a simple procedure for adjusting the gearbox rocker, especially since adjusting the rocker will take you no more than half an hour.

The gearbox slide is necessary to prevent random switching of gears due to the simultaneous movement of the sliders. Often, the entire transmission suffers from an incorrectly adjusted rocker, and as a result, you are at risk of malfunctioning the entire gearbox. In our previous articles, we have already talked about this detail several times, for example, in the article: About that, and also in the article:. In addition, the issue of engaging gears and gearboxes is addressed in.

Adjusting the gearbox slide requires the presence of an assistant, in which case the result, and the work itself, will be of better quality. It is fashionable to adjust the slide in several ways; below we will talk about each of them in more detail.

How to adjust the rocker on a VAZ 2110 with your own hands

Before adjusting the gearbox linkage, it is necessary to perform a number of preparatory work:

1. Drive the car into the pit.
2. Tighten the handbrake and install the wheel chocks.

Method No. 1 - adjusting the rocker according to the rear speed.

1. Loosen the clamp.
2. Engage reverse and position the lever as you would like it to be in that position.
3. Then tighten the clamp and check how the rocker works, whether you are satisfied with the current position of the lever and the operation of the rocker.

Method No. 2 - adjusting the scenes at first speed.

This method is used, as a rule, when the first method did not produce results.

1. Turn on first speed.
2. Loosen the rocker clamp.
3. Turn the rocker drive counterclockwise until the gearshift lever begins to rest against the plastic reverse speed stop.
4. Tighten the clamp and check how everything works.

Method No. 3 - adjusting the scenes in neutral.

If you do not have a plastic stopper, the adjustment is made in neutral gear.

To adjust the neutral position of the gearshift lever, you need to accurately calculate the depth of the shift of your gearbox to the car's driveshaft. Sometimes such manipulations end in the appearance of annoying rattling of the lever.

If adjusting the rocker does not lead to anything and there is still a problem with switching, replace the rocker completely or ask for help from specialists.
