Design, malfunctions and work on replacing the VAZ 2114 clutch

Prevention of clutch failures

To prevent such breakdowns from occurring, you need to adjust the clutch in a timely manner, do not make frequent and sudden movements at the beginning of the movement, lower the pedal completely if you make high speeds, try to purchase high-quality spare parts.

In any passenger car, the most important element is the basket, also called the drive disk, which is installed on the internal combustion flywheel. One of the clutch elements is another part called the release bearing, with the help of which the amplifier is transferred from the fork installed to the petals of the basket. It is located inside the disk and is connected to the input shaft using splines.

Important! The replacement sequence is generally not complicated, and if you carefully review the instructions, any driver can do it. For a replacement that occurs for the first time, it is better to do it with someone who already knows how to do it. With such an installation, the work will be accelerated and its correctness will be guaranteed.

It is better to carry out such work in places designated for this purpose, mainly garages with special pits and overpasses, or take them to a service station. Even if this opportunity is not provided, you can do it yourself by lifting the hood of the car with blocks of bricks or any other materials.

Basic faults

The clutch is an essential part of a car using a manual transmission. In addition to knowledge about how the clutch works, it is important to have an understanding of malfunctions.

The most common of them:

• The clutch does not disengage completely. Air entering the release drive creates the feeling of a sinking pedal, as a result of which the driver cannot completely disengage the clutch;
• the clutch does not engage. Common cause: cable break;
• The clutch pedal refuses to return to its original position. Cause: the return spring has failed or is disconnected;
• loud noise when disengaging the clutch. The noise indicates wear of the release bearing;
• The clutch is not fully engaged. There are many reasons: wear of the drive disk linings, faulty springs, small pedal travel.

Improper operation and late replacement

Frequent causes of the above malfunctions are:

• untimely clutch adjustment;
• frequent and sharp jerks when the car starts to move;
• high engine speeds when the pedal is not fully released;
• towing a car;
• manufacturing defect;
• Typically, replacement involves installing a new release bearing, which is part of the clutch mechanism.

Observing clear signs of a malfunction, drivers are often in no hurry to replace it. This attitude leads to complete destruction of the elements and the car’s unsuitability for use.

Clutch replacement price

You need to decide whether you will trust the services or make the replacement yourself.

Estimated cost for replacing the clutch and adjacent parts in service centers:

These prices include the cost of specialist work. Replacing it yourself allows you to save a lot: the average price of a clutch kit is 3,000 rubles.

Which clutch to choose for VAZ 2114

When you choose a clutch kit for a VAZ 2114, first of all you will need to pay attention to the manufacturer’s brand, as this can be very important. If you purchase an inexpensive set, it will not work for long, will not withstand extra loads and will have to be replaced again. Subsequently, such savings will be reflected in your costs and time.

You also need to take into account that the quality of this product you purchased will directly determine your personal safety, but also the safety of those around you and the passengers you will carry, therefore it is impossible to predict when some part will fail if it cannot withstand the load. Therefore, you should first of all always pay attention to the quality of the manufacturer, and not to the cost; the difference in price seems to be small, but the quality of not so expensive ones is unimportant and the possibility of breakdown is much higher.

Important points

• When replacing the clutch, it is necessary to pay close attention not only to the condition of the discs, but also to the condition of the release bearing, which was mentioned above. After removing it, you need to turn it several times by hand. If rotation is difficult or a creaking or crackling sound is heard during scrolling, then the bearing needs to be replaced. If this is not done, all the work on replacing the clutch discs will be useless, since they will again become unusable.
• The gearbox shaft and adjacent parts should be cleaned of dirt very carefully; it is best to wash everything with kerosene and wipe dry with a clean rag.
• The above is a method for replacing the clutch with complete removal of the gearbox. But sometimes car enthusiasts do without removal. To do this, the bolts that secure the box to the engine are carefully unscrewed (one at a time). In their place, studs are installed, which are slightly thinner and at least three times longer than the mounting bolts. These pins serve as guides along which the box can be moved slightly to the side. This creates a gap between the engine and the gearbox, through which the clutch discs are removed. This method is less labor-intensive, but it has its drawbacks: it will be impossible to get to the release bearing and it will not be possible to thoroughly clean the gearbox shaft from dirt.

As you can see from this article, replacing a clutch is a very labor-intensive operation. Therefore, it is necessary to follow the proposed instructions exactly. You should also not forget about safety precautions, especially when it comes to removing the gearbox. This is a very heavy unit and you should be extremely careful when handling it.

The procedure for replacing the clutch on a VAZ 2114

When replacing the VAZ 2114 clutch, it will be possible to use a much simpler option - without removing the right CV joint and without changing the oil. If you cannot do without draining the oil, you will need to change the release bearing or fork.

When removing a car's gearbox, you should pay attention to the fact that being in a suspended state makes it difficult to access the space under the hood. While the vehicle is still on wheels, to further simplify the work, everything that will subsequently interfere with dismantling the box is disconnected and unscrewed.

To work, the following tools are needed:

When everything necessary is prepared and the car is installed in the desired state, we begin the phased replacement.

Step-by-step replacement of the clutch on a VAZ 2114

• To do this, you first need to remove the wheels, disconnect the battery from the power system, dismantle the air system and sensor, then disconnect the clutch cable, and replace it immediately if necessary.

• The cable in the car is needed for normal traction of the car with the track. It is installed mainly in passenger cars with a manual transmission, so it is present on these models.
• Using a bushing, it is attached to the shield with special screws. Therefore, when replacing the clutch, it must be checked for serviceability. In the event of a breakdown, it must be replaced to avoid problems on the road, since it is an important component of the system.
• During a complete or selective replacement, the drive shaft is disconnected from the gearbox and the oil is drained, after which you can remove the gearbox, but you need to do it carefully so that all parts are checked and replaced.
• Use a socket wrench to unscrew the bolts that secure the gearbox to the cylinders, and with a 8mm spanner, remove the bolts that secure the pressure plate to the flywheel. After all this has been removed, we also inspect the driven disk, also called the basket, you need to make sure that it is in good condition, since the working surface should not have large gaps or cracks.
• Then you need to pry off the ends of the rotating spring that secures the release bearing, remove it, the clutch and the rotating spring. After inspecting all the parts, we change what is faulty, for example, if you twirl the bearing in your hand and hear a crunching or noise, then it needs to be replaced.

• Next you need to remove the switch plug. All parts must be wiped with kerosene to remove old grease and dirt.

• Replacing a part is still half the battle. Before driving the car away, you need to adjust the clutch, it is better to do this with a knowledgeable person, if possible, as a result of this, the service life of not only the clutch, but also all the parts adapted to it depends.

• After this, we tighten the new bearing, coupling and spring. To center the crankshaft, a mandrel is inserted into the hole and the driven disk is installed on it, and the disk is screwed into the flywheel.
• Having completed all these installations, further replacement occurs in the reverse order, but do not forget to refill the oil after installing all the parts.

• It is better to replace the clutch in a timely manner; this improves long-term performance, so if possible, avoid complete wear of the part.

If you still have questions about replacing the clutch on a VAZ 2114 with your own hands, watch this video:

How to change: sequence of actions

1. The car is installed on the inspection hole. Wheel chocks are placed under the rear wheels. The front wheels are jacked up and removed.
2. The hood opens and both terminals are removed from the battery.
3. Using open-end wrenches, the air filter and the sensor next to it are removed.
4. Access to the clutch cable is provided. This cable is disconnected with a 10mm open-end wrench.

Good to know

After all, at this stage the replacement of the clutch ends. Such instructions can be used on all passenger cars of this brand, the only difference is that the elements themselves may differ. The disc, clutch or basket will be reliable if the engine is very powerful. The more powerful it is, the more reliably all the parts of the mechanism will work.

But in any case, you need to try not to give the car high speeds in order to increase its resource.

It is possible to replace the clutch without removing the box. The replacement is almost identical to the first, but the difference is that the box can simply be moved to the left side, the disk is changed through the gap formed between the engine block and the crankcase.

Replacing the clutch yourself not only saves your resources, but also gives you a wealth of experience in such a difficult task. You should know that when replacing the clutch, the release bearing must be replaced.

Take care of your iron horse, promptly replace all parts that have become unusable, and your swallow will serve you for many more years.

Operating principle

VAZ vehicles use a single-plate dry closed clutch with a diaphragm-type pressure spring, for which the operating position is engaged.

The clutch includes the following components:

• body-protection;
• bearing switch;
• main shaft roller bearing;
• pressure disk;
• compression spring;
• flywheel;
• secondary friction disc;
• scale;
• crankcase;
• transmission main shaft;
• plug switch;
• second bushing-switch;
• toggle switch;
• fixation bolt to the flywheel.

The operating principle of this mechanism is as follows. After pressing the clutch pedal of the VAZ 2114, the drive moves the fork, which acts on the clutch bearing. The bearing, in turn, presses on the diaphragm spring of the pressure disk. As a result of the impact, the spring petals bend towards the flywheel, and its outer edge moves away from the pressure plate, thus releasing it. The transmission of torque from the running engine to the transmission stops.

When adjustment is required

Adjusting the VAZ 2114 clutch may be required in the following situations:

1. The clutch has been completely replaced.
2. The clutch was repaired and its individual elements were replaced.
3. The clutch travel is too large or, conversely, insufficient.

If everything is clear with the first two reasons, then in the latter case simple measurements should be performed. To do this, you need to measure the distance between the minimum and maximum positions of the pedal (that is, in situations when the pedal is pressed to the floor and when the pedal is freely released). The optimal value of this distance is in the range from 12 to 13.5 cm. If in fact it turns out to be larger or smaller than the specified dimensions, it is recommended to make an adjustment.

If the clutch travel exceeds 16 cm, then you should immediately stop all driving and make adjustments as soon as possible.

In addition, in some cases, too much stroke may indicate severe wear of the friction linings located on the driven disk, as well as the need to replace them.
