Repair, features and technical specifications
Inside a VAZ 21118 car, like any other, there is always a gearbox. For a model such as Kalina 1118, this device is a mechanical type design, which is equipped with one reverse stage, as well as 5 forward stages.
Gearbox from Lada Kalina.
In Lada Kalina, the gearbox is structurally combined with a differential, the main gear. Transmission differential repair should also take this into account.
The mechanism body of the VAZ Kalina car is presented in the form of three aluminum copper crankcases:
- Back cover.
- Box.
- Clutch.
Special sealants are applied between them when assembling and repairing the gearbox.
Technical features of the gearbox
The drive gear block is engaged by the input shaft. This is important to consider when repairing a gearbox. As for the input shaft itself, a constant clutch is created for it with the front gear elements that perform similar functions.
When repairing the secondary shaft, we must remember that it has a hollow structure. It is thanks to this that the oil reaches the driven gears without any problems.
Inside the mechanism you can also find driven bearings and synchronizers. When replacing the backstage on your own, this part can also be replaced. This also requires repairing the gearbox driveshaft.
The design of the gearbox is such that repairs cannot be done without the use of special circuits. In this case, the radial clearance on the roller bearings is no more than 0.07 millimeters.
Repairing the gearbox is also a rather complicated process. Especially considering that 0.04 millimeters should not exceed the same figure, but for ball analogues.
Location of the checkpoint backstage on the Lada Kalina.
The oil sump is responsible for supplying oil. It is located in the area of the front bearing, fixed behind the output shaft. Major repairs often affect such details. If you select the desired thickness of the rings, it will be possible to adjust the tension indicator. The dimensions of the seals are easy to find in the instructions; these parts can be replaced without problems, even at home.
When repairing the gearshift knob, you must remember that the driven gear of the gearbox on this machine is attached to the differential flange. Through the saloon, the atmosphere is combined with the box itself, located at the top of the structure we are considering.
Lever repair is not the only operation that needs to be carried out from time to time. Sometimes it is necessary to replace bearings; this is done when extraneous noise appears. A gearbox repair kit must be purchased if excess noise becomes noticeable when pressing or releasing the clutch pedal.
All control drive elements of the Lada Kalina gearbox.
The repair manual says that the box is controlled using a drive, which consists of several elements:
- Switch rod.
- Spherical bearing.
- Lever arm.
According to the manual, cable structures are always equipped with jet traction, then the gears do not turn off on their own. One of the ends of the rod is connected to the lever, and the other to the motor. If the seals of the internal joints are faulty, it is necessary to carry out independent repair of the gearbox. But before replacing them, you need to completely change the oil. The front wheel drive is completely disconnected.
Servicing the gearbox involves using a screwdriver to remove the necessary parts. But you will need to purchase a mandrel with the necessary parameters in order to carry out the pressing.
Three axes are present on the shift system. One axis is equipped with a three-arm lever for selecting and disengaging gears. There is no gearbox on the second axle, but there are brackets that block rotation. After every 75 thousand kilometers, this design is completely changed. Gearbox lever play should also alert you, as should failure of other parts.
Choosing the best oil
When choosing oil for the gearbox, and for other units of the Lada Kalina, you must take only the original fluid. Since, recently, the market has a significant share of fakes, it is necessary to approach the issue carefully.
Thus, Kalinovody chooses to fill with TNK TRANS KP Super oil. As practice shows, the gearbox on it begins to operate more quietly, and the speed shifts smoothly. Monitor the oil level in the gearbox.
And in an 8-valve engine they prefer to pour what is recommended by the factory, just like in a 16-valve engine. A 16-valve engine is more capricious, so you need to be very strict when choosing oil.
A table of recommended oils for Kalina, as well as their coding, was found in the factory service manual.
It is worth remembering that only transmission oil is poured into the gearbox. After a major overhaul, at the time of break-in, you can use the simplest thing - TAD-17.
Consequences of untimely replacement
Since, over time, gearbox oil loses its properties, both physical and chemical, this can cause the following consequences:
- Wear of shafts and gears. This is due to the fact that after 150,000 km the oil loses its physical properties, namely its cooling effect. Thus, rotation of shafts and friction of gears leads to heating and increased wear.
- The loss of chemical properties will also lead to wear and accumulation of metal shavings in the oil, which will affect not only the gears, but also the bearings.
All these reasons can lead to increased wear, which will lead to premature overhaul of the gearbox.

Replacement process (briefly)
Read more about changing the oil in the material: changing the oil in the gearbox on a Lada Kalina.
Changing the oil in a Lada Kalina gearbox is, on the one hand, simple, but on the other, not so easy. To do this, you will need tools, namely: a jack, flushing oil, a 17 mm wrench and a container for working off.
Now that everything is ready, let's begin the work process itself:
- We place the car on a lift or pit.
- Remove the air filter.
- Using a dipstick, check the amount of oil.
- We remove the lower engine protection.
- Unscrew the drain plug on the gearbox.
- Draining the oil can take up to 40 minutes.
- We tighten the drain plug, while not forgetting to replace the O-ring.
- Now, insert a watering can with an extended tube into the dipstick.
- Fill in about 3 liters of oil.
- We wipe the dipstick and insert it, and then remove it. We look at the level, it should be between the maximum and minimum indicators.
That's all, the oil in the box has been replaced. We drive 10-15 kilometers and look at the level indicator. If necessary, add oil.
Removal and installation of the gearbox
Servicing the gearbox assumes that the mechanism will have to be removed and its position changed. Before doing this, you need to install the vehicle itself on the lift. The ignition must be turned off completely and the parking brake must be used.
How to repair a gearbox? To do this, disconnect the minus terminal from the battery. The hood must be opened completely. Any manual on gearbox repairs writes about this.
The oil filler cap is also removed. It is necessary to install the previous item after the screen is removed. The gearbox requires loosening the clamp responsible for fixing it. The inlet pipe hose must be disconnected from the corresponding sensor. Gearbox lever play requires the same actions in practice. Then you need to unscrew the air intake nut.
The repair progress further depends on the specific malfunction.
Gearbox Lada Kalina after dismantling and disassembly.
The gearbox can be installed in its original place after the 1st speed repair is completed. SHRUS-4 lubricant is applied to the outer surface of the corresponding bushing in the clutch in a very thin layer. This will also help if the gearbox is loose. The pin fixing bolts are removed from the steering knuckles.
Gearbox lever jammed
In any case, it is necessary to remove the last fastener after the bolt nut securing the left suspension arm has been unscrewed to the body bracket.
Repairing a box cushion is not complete without many of the steps described above.
After this, all that remains is to remove the lever. Another rather important element is the gearbox fork; its condition must also be monitored.
You will need to drain all the remaining oil into the container. A complete gearbox repair also involves removing such parts as the wheel drive from the gears of the differential axle shafts. The plugs are placed in the place where the gears used to be. After the gearbox adjustment is completed, they usually proceed to installing the left suspension support and brackets for the rear of the car.
Any such work, including repair of the secondary shaft, must take into account the general design of the gearbox and the basic principle of its operation. It contains a book on repairing the box. The same applies to the functionality of the component elements, otherwise the gearshift lever support cannot be replaced, like other parts.
Dismantling of the Lada Kalina gearbox at a specialized service station.
The features of the repair are fully familiar only to real professionals. It is better to entrust the work to them if you do not have the proper experience or some practical skills.
It is necessary to completely rinse the mechanism with water before disassembling it to identify a gearbox malfunction. Problems during repair may arise if the part itself is not installed on a special stand. The bracket, which is responsible for fixing the clutch cable and engine suspension, is completely dismantled.
Many people give useful advice on replacing a VAZ gearbox. According to them, in any case you will need to remove the rear cover of the crankcase.
Which oil is better to choose?
Today, few people may have problems choosing fuels and lubricants, since the market is literally teeming with all kinds of manufacturers. And oil in this case is no exception. The main thing to consider when choosing a transmission fluid is to buy an original, not a counterfeit one. Do not listen to counterfeit sellers, no matter how much they list the benefits of Chinese oil to you. This does not mean that the oil has to be expensive.
In practice, the use of even the simplest and relatively inexpensive oil, such as Lukoil semi-synthetic, is completely justified. As the owners of Kalin say, a Lada can even travel more than 300 thousand km without major repairs using this oil. As practice shows, if you pour TNK Magnum oil into the gearbox, the manual transmission (manual transmission) will be much quieter. In particular, extraneous sounds and noises will disappear, and during winter cold, gears will be switched on much easier. We invite you to familiarize yourself with the recommendations for choosing transmission fluid from a domestic manufacturer.
Remember, when buying oil, forget about additives. Since modern transmission fluids - the same applies to engine fluids - have all the necessary components for the productive functioning of all components and assemblies of the system. The use of additional additives can destroy the structure of the consumable element (whether it is oil or another liquid), as a result of which it will have to be completely replaced.
How to remove the gearbox
The fork fixing bolt and nut must be unscrewed after the input shaft stopper has been removed. The same thing will have to be done if it is necessary to replace the short-throw gearshift link.
The spline must be removed from the secondary shaft. The box assembly diagram assumes the reverse procedure.

Choice
ATTENTION!. There are two types of clutch installed on the Lada Kalina:
- 190 mm (three bolts at the starter),
- 200 mm (two bolts at the starter).
You can tell exactly which one you have after analysis. We recommend doing just that. But you can tell by the starter, or rather by its mounting.
We installed VALEO 828003 on our editorial Kalina. It cost about 3,500 rubles per set.
