Engine mounts for VAZ 2114 - how to check, replacement

How to check engine mounts on a VAZ 2114

The engine mount on any domestic car is a rubber-metal silent block on a bracket. It connects the cylinder block body to the stationary parts of the car. On the VAZ 2114, the factory provides three such supports:

• the front one, also known as the bottom one, connects the crankcase to the beam;
• the right one, also known as the side one – between the engine and the spar;
• rear - attached to the gearbox housing and body.

Also, sometimes an additional mount is installed on the VAZ 2114, which is attached to the cross member on one side and to the clutch housing on the other.

It is widely believed that the main task of airbags is to provide ride comfort. This is only partly true. In fact, their main task is to minimize the transmission of engine vibrations to transmission parts. With a rigid connection, the gearbox would become a consumable item; in 30-40 thousand kilometers its “internals” would wear out completely. Therefore, in particular, rubber in silent blocks cannot be replaced with polyurethane.

Replacing the rear support

1. Just like with the left cushion, we need to place a jack under the gearbox.
2. First, unscrew the bolts securing the support to the car body, and then to the box body.

   

3. We clean the mounting area and install a new part.

Having finished the work, we check the correctness of the actions performed and the reliability of the connections. Afterwards you can start the engine.

Signs of wear

Since the function of the engine mount is to dampen vibrations, if they are noticeable even at idle, this indicates a problem. Among other signs of wear on the airbags on the VAZ 2114:

1. Vibration of the gearshift lever. This indicates that all motor vibrations are transmitted to the box.
2. If you open the hood, strong vibrations of the engine are visible.
3. Uneven car operation. The fact is that when the silent blocks are heavily worn, the crankcase begins to move slightly relative to the clutch. Because of this, the crankshaft position sensor (CPS) constantly produces different signals. The ECU is forced to mistakenly “catch” the revolutions to eliminate the imbalance.

Self-replacement

Before replacing the pillows, it is necessary to diagnose their condition. The condition of any silent blocks is checked with a mount: with its help you need to influence the support, simulating the movements of the engine during operation. If:

• rubber ruptures are visible,
• the bushing of the silent block touches the joints,
• the motor moves easily when pressed and hits the protection,
• the support bracket is broken,

the part needs to be replaced. Even if the signs of wear are not so noticeable (for example, the rubber is cracked but not torn), it is better to replace them as a set. Silent blocks lose their elasticity over time and begin to perform their functions poorly.

There are regular and reinforced supports for the VAZ 2114 on sale. The second type uses a harder rubber compound, but they are more durable only in quiet driving mode. Fans of sharp starts and braking will have to change any of them every 15-20 thousand; for other drivers they can last 50 thousand kilometers. This is the answer to the question of how long the supports last.

Front engine support VAZ 2114

On a VAZ 2114, the supports can be replaced independently, without contacting a car service center. It is more convenient to use a pit or overpass, but you can do without them. To do this, the car is jacked up and placed on supports (bricks or tree stumps). If crankcase protection is installed, it must be removed.

Replacing the front support. You need to jack up the oil pan. First, use a 17mm head to unscrew the 4 bolts securing the bracket to the crankcase, then the silent block bolt. To remove the bolt, you need to use a jack to get it into a position where the engine will not put all its weight on it. When installing a spare part, it is important to lubricate the silent block bolt well: not only the threaded part, but also the body. It is in contact with the metal sleeve, so it can stick.

Side engine support VAZ 2114

Replacing the right support is similar, with the difference that it is better to jack the gearbox housing rather than the engine. Another option is to install a jack in the area of ​​the oil filter housing. It is attached to the crankcase with three bolts. Another trick is that the right pillow needs to be changed by two people. Without a side stop, the motor moves up, not down. The jack will not help here, so an assistant must press on it so that the silent block bolt can be secured.

Replacement of the rear support is the most difficult task if done without a pit or lift, requiring some skill in performing auto mechanic work and perseverance. It is located at the connection between the engine and gearbox, so you will have to work in a confined space. In addition, when unscrewing the bolts from the body, the key may rest against the gearbox housing.

Replacing the front engine mount of a VAZ 2114

How to replace a VAZ 2114 engine mount will be discussed in our article. The power unit of any vehicle begins to vibrate strongly from the moment it is started, and if its vibrations (which increase with power gain) are not suppressed, one can expect dire consequences for the car frame.

Despite the fact that on older models of the domestic automobile industry, special cushions made of dense and durable rubber acted as dampers for engine vibrations, but the engine still continues to lie on the frame.

The designers have significantly modernized the engine compartment of the latest generation front-wheel drive models (for example, on the VAZ-2114), adding specially designed cushions, which are now also supports for the power unit.

However, under our operating conditions for automotive vehicles, these elements are subject to high loads and wear out faster. In this publication, we will discuss in what cases it is necessary to replace the engine mounts of a VAZ-2114, and how to carry it out yourself.

There are three pillows on the “fourteenths”:

1. The front (also called the bottom) connects the crankcase to the beam;
2. Right (or side - located between the motor and the spar);
3. Rear – connects the box and the body.

Engine mounts are constantly under heavy load, even when the car is just standing still, which cannot but affect their condition. Over time, engine mounts, made of durable rubber, become unusable and require replacement, which is indicated to the car owner by characteristic signs.

Design and technological features

Since in the “fourteenth” model the entire load from the engine falls on the front suspension, accordingly, the chassis is made of materials with an increased margin of safety, and its design must strictly comply with established standards. Durable rubber mounts of the VAZ-2114 engine are used as a damper for vibrations of the power unit under various loads.

Since high demands are placed on this part, it is extremely important to purchase only original and certified supports, since only they are suitable for use in our conditions.

In the design of the front part of the car frame and its suspension, the engine mount is one of the important elements, while its independent replacement is quite within the capabilities of a car owner who has even the most minimal concepts in plumbing.

The main thing in the repair process is to complete the entire technological sequence of actions, then the installed part will serve for a long period of time.

When do you need to change engine mounts on a VAZ-2114?

Since rubber elements are included in the design of the supports, during operation they are subject to increased loads, wear out and lose their properties. This can be judged by the noticeable vibration that is clearly felt inside the car.

The following factors affect the service life of the element:

• load;
• temperature regime;
• operating conditions of the vehicle.

It is very important to replace the airbag in a timely manner; if this is not done, the part will simply become unsuitable for further use, and only then will cause a more complex and expensive repair of the power unit suspension.

If you hear extraneous noises in the area of ​​the engine compartment when driving, and suddenly noticeable vibration appears in the interior of the VAZ-2114, it is necessary to perform a visual inspection of the engine mounts, and if damage is found, replace them immediately.

Advice! You need to purchase only original products, the quality of which is confirmed by the manufacturer’s guarantee. Otherwise, the pillow will not cope with its functions and will quickly collapse.

When replacement is necessary

Since the pillow has rubber inserts, it loses its elasticity over time. This becomes noticeable even in the cabin, as an unpleasant vibration appears. The replacement period for a part varies, depending on weather conditions and sudden temperature changes. It is these factors that affect the structure of rubber: it becomes harder.

If you do not replace the cushion at this stage, then in the future the part will begin to deteriorate, which can lead to more serious damage to the engine mount. If while driving you hear a knocking noise under the hood and notice increased vibration, you should conduct a visual inspection and, if defects are found, begin preparing for repairs.

Tip: We recommend buying only high-quality pillows from the manufacturer with a guarantee, since a bad part will not properly dampen vibration and will begin to quickly deteriorate.

Replacing the engine mount

To perform this activity, you should purchase a set of power unit supports, since it is not practical to change them one by one. To replace these elements yourself, you will need the following tools:

1. Set of wrenches.
2. Scrap.
3. A pair of powerful jacks.
4. Glue.
5. Durable cable.

Advice! It is worth inviting an assistant in advance, since during certain stages of the repair it will be necessary to lift quite a lot of weight. We recommend using an engine disassembly stand for these purposes.

The process for replacing pillows varies. Sequence of actions when replacing the front engine mount:

• it is necessary to immobilize the car in advance by tightening the parking brake and placing shoes under the wheels;
• you can only get to the support after dismantling the upper protection of the power unit;
• Let's start jacking up the engine. To avoid damaging it when doing this, it is worth preparing a strong board in advance, which is placed between the jack pusher and the bottom of the motor;
• you can unscrew the bolt securing the pillow to the bracket, since it is no longer under load;
• We carry out a similar procedure with the bolt securing the support to the engine;
• remove the worn element and install a new one.

Sequence of actions when replacing the rear and side supports:

• The car's transmission must be hooked up with a cable, and then a jack must be placed under it;
• loosen the bolt securing the gearbox to the support;
• We perform a similar procedure with the nuts securing the power unit cushion;
• Having jacked up and raised the gearbox, remove the nuts and bolts securing the cushion;
• remove the worn out part and install a new one, assembling everything in the reverse order.

The side cushions of the VAZ-2114 engine change in the same way. The only thing is that if the starter is large, it will need to be dismantled, since it will not be possible to get to the support mounts properly because of it.

This is the entire process of replacing worn out engine mounts. As you can see, it will not cause any particular difficulties, and its timely and competent implementation will help to avoid serious problems in the future and save on expensive repairs.

Attention! I advise you to save not only on repairs, but also on fuel. How to do this - here is a separate article on this topic.

How to change supports

To replace, you will need to purchase front, left and rear airbags. Experts advise replacing the entire set during repairs, since after replacing one part, another one may break after a while. The average cost of parts is 2000 rubles. If you have the necessary tools, you can do the repair yourself and save on car service.

List of tools

To replace the pillows we will need:

• 2 good jacks;
• metalworking tools;
• scrap;
• steel rope;
• glue.

Tip: At some stages you will need to lift a lot of weight, so it would be a good idea to invite a neighbor or a fellow car enthusiast here.

Replacing the front airbag

The repair of each support has its own characteristics. Replacing the front airbag is carried out as follows:

1. Put the car in 1st gear or the handbrake so that it does not move.
2. To gain access to the support, remove the upper engine protection.
3. Raise the engine with a jack. To avoid damaging its lower part or other elements, place a wooden board underneath.
4. When we have freed the support from the load, we can unscrew the bolt that connects it to the bracket.
5. We unscrew the bolts connecting the pillow to the motor.

   
   Removing the bolt that secures the cushion to the engine

6. We remove the old part and install the new one.

Replacing the rear cushion

Here we will need a steel cable to make it more convenient to work with fasteners.

1. We hook up the gearbox with a cable and install a jack under it.
2. Slightly press out the bolt connecting the gearbox to the support.
3. Unscrew the nuts securing the support to the body.

5. We replace and reassemble in reverse order.

What is this?

If we talk about the VAZ 2114 model, then there are three supports, two of which are intended directly for the gearbox, and another one for the engine itself.

The main purpose of pillows is to reduce vibrations.

When the car drives, serious vibrations occur, which are transmitted to the body from the power unit. To ensure the necessary level of comfort while driving and not to be distracted by extraneous noise or shaking, special supports are mounted on the car. If you remove them, driving a VAZ 2114 can be compared to riding an old wooden cart.

Causes of malfunctions

The most important problem that pillows face is the loss of elasticity of the material. This is due to the fact that the supports are made of rubber. Over time and with use, these elements lose their original characteristics. Various factors accelerate the wear process of bearings:

• Regular exercise;
• Long service life;
• Cold;
• Heat;
• Temperature changes, etc.

If elasticity decreases, this entails the formation of cracks and delamination of the material.

Replacement is purely a matter of time. But the procedure for changing the front and all other pillows should be carried out on time. If you drive for a long time with worn out bearings, this will result in a negative impact on engine performance. Then the repair will cost much more than the cost of new supports.

The main advice is to periodically check the condition of the supports for wear. If you detect a fault in a timely manner, you can replace it yourself and significantly save on car repairs.

Price issue

If you do everything correctly and in a timely manner, then your costs will be insignificant. You will have to purchase new supports and contact a car service. Of course, it is quite possible to do it on your own. This is a matter of desire and availability of appropriate skills.

How much will it cost to replace engine mounts? We suggest that you familiarize yourself with the current prices for the VAZ 2114.

There is no need to pay someone, since the replacement can be done by yourself.

Engine mount malfunctions

The main damage to a pillow is loss of elasticity. The support is made of rubber, which loses its properties with prolonged use.

This is due to constant loads accompanied by changing weather conditions (cold, heat). In the future, the pillow will begin to deteriorate: it will crack and delaminate.

To prevent destruction of the rubber support, it is necessary to inspect it regularly. If damage is detected, the part should be replaced, otherwise strong vibration and extraneous knocking will be felt in the cabin, which will soon affect the operation of the engine.

It is better to replace the airbags in a timely manner than to later spend money on expensive repairs or purchasing a new engine.

The cost of engine mounts depends on the manufacturer, the minimum price for the front support is from 600 rubles, the rear and left ones are 500 rubles each. Average prices start at 1,200 rubles for the front, and 900 rubles for the rear and left.

It is possible to buy a set of three pillows from 3,500 rubles.

To replace engine mounts at a car service center, you will be asked for 1,500 rubles, but you can replace them yourself.

Replacement

We have already noted that there are a total of three supports on the VAZ 2114. But it’s not uncommon for car owners to decide to install a fourth—an additional airbag. It serves to connect the crankcase and transverse the front suspension. This reduces wear and vibration and increases the level of comfort. But keep in mind that with such a modification you will have to look for a new place for the ignition module.

Now let's talk in more detail about the three standard pillows. Replacement of each of them is carried out in a certain sequence and according to the appropriate algorithm.

Front

To change the front engine mount, follow the instructions.

1. Drive the car into a pit with a flat surface. Stop the wheels, turn on the handbrake, and put the transmission in first gear. This is a guarantee that the car will not roll away unexpectedly for you.
2. Remove the crankcase protection and give yourself access to the front airbag.
3. If the car has been in service for more than a year, and you haven’t touched the supports for a long time, then be sure to treat all fasteners with WD40 or another effective “fighter” against rust.
4. Using a jack, you need to slightly raise the power unit. In this case, be sure to use a wooden beam as a spacer so as not to damage the motor. Keep an eye on the radiator and fan while lifting the engine. They should not break, otherwise you will not avoid serious expenses.
5. There is a rather long bolt on the body cross member. It secures the support and bracket. It needs to be unscrewed.
6. Now the bolts that connect the motor block and the pillow are unscrewed.
7. All that remains is to remove the damaged element and replace it with a new one.
8. Assembly is performed strictly in reverse order.

Here, in addition to the standard set of tools, you will also need a cable.

1. Using a cable, pick up the gearbox and place a jack under it.
2. If your car has a large stator (an old-style device), you cannot do without dismantling it.
3. Now we remove the bolt that connects the bracket and the support.
4. Remove the worn out cushion.
5. Place the new element in place and reassemble.
6. Before firmly tightening all the fasteners, make sure that everything is exactly in place.
