Replacing engine mounts on a VAZ-2114 with your own hands: front and all others


Welcome to VAZ Repair.
Today, in the “VAZ 2114 Repair” section, I will talk about what an engine mount is, the signs indicating a faulty mount, and also how to replace the VAZ 2114-2115 engine mount at home. Newer VAZs, despite criticism, are still evolving compared to their predecessors. Thus, in newer models, instead of a standard engine mount, the manufacturer used a so-called engine mount, the appearance of which made it possible to significantly increase the level of comfort in domestically produced cars.

The VAZ 2114 engine mounts act as shock absorbers (dampers) that dampen vibrations coming from the power unit. Such pillows will not allow vibrations to transfer to the body, and then into the interior of the car, which makes the ride more comfortable and enjoyable. In addition, the airbags soften the impacts coming from the wheels when driving through areas with poor road surfaces. Engine mounts are practically the same silent blocks that are used in the design of the chassis.

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.

Features of the procedure for replacing motor mounts

It is necessary to ensure easy access to the cushions, so in addition to wrenches, you will also need a good jack. Let's look at the list of measures to replace a defective cushion using the example of a rubber-metal product:

  • Loosen the nut securing the airbag to the body.
  • Jack up the engine and remove the bolt.
  • Unscrew and remove the faulty support.
  • We install a new one and tighten it.
  • Jack up the engine and insert the mounting bolt.
  • Tighten the bolt and lower the motor.

Self-replacement

If a visual inspection reveals problems in the pillow, it should be replaced as quickly as possible. Start by purchasing a new part. It should be noted that it is better not to buy this spare part for disassembly, even if it is in good condition. In this case, saving money may cause more harm than good. Ideally, it would be to buy an original part.

  • Remove the terminals from the battery. Raise the car to a height that will allow access to the engine from below. In this case, you can use a jack and wooden blocks as support.
  • Raise the engine with a jack to release the load on the required part.
  • Remove the bolts that secure the cushion to the engine and body.
  • Place the new part in place, guiding it properly into place. Tighten the mounting bolts well. It's best to tighten them while the engine is running to avoid excessive vibration in the future.
  • Once you have finished installing the cushion, put all the dismantled parts back in place.

In each individual case, it may be that there is no convenient access to replace the part. In this case, try to remove those components that prevent you from making a replacement.

Sometimes this operation may require another person to help guide the motor while you push the part into place. If we are talking about the top cushion, then, as a rule, it will not be difficult to inspect it and, if necessary, replace it. It will be possible to do without a hole.

Periodically check the condition of the engine mounts on your car. As you can see, this is not at all difficult, but it can help avoid many problems in the future and provide you with a comfortable ride in any conditions. Remember that a car feels when it is being looked at and then thanks its owner for a long and good service.

What is needed for this


Use a hydraulic or other jack.
To carry out the test, you will need:

  • hydraulic or other jack you have;
  • some kind of safety support, such as a wooden block or something else;
  • lever – a pry bar or a strong stick is perfect for this.

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.

Engine pad

Left

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.

Path to the left pillow

Rear

A cable will also come in handy here. How exactly to perform the replacement? Simple enough.

  1. By analogy with the left support, pick up the gearbox and place your jack under it.
  2. Loosen the fasteners that secure the gearbox and rear support slightly.
  3. Loosen your grip on the two nuts on the body that hold the rubber mount in place.
  4. Raise the gearbox slightly with a jack and unscrew both nuts.
  5. The bolts that hold the pillow are unscrewed from the box itself.
  6. Remove the damaged element, install a new support and reassemble in the reverse order.
  7. If there is rust on the fasteners, we recommend cleaning it or replacing the bolts with similar new ones.

Changing these elements is not difficult, but we still recommend that you first consult with specialists and watch training video instructions. This will allow you to take on the work with your own hands more confidently and save an impressive amount of money on car service services.

To ensure that new engine and gearbox components serve for a long time and reliably, we recommend that you do not skimp on their purchase. Buy high-quality products right away that will last you many years.

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.

Self-installation

If you purchase a VAZ 2114 without a driver's airbag, it is possible to modify the car. To do this, install steering wheels from Priora, complete with wiring harnesses, sensors and control unit. The cars are related in class and concept, so you can install such a cushion with some effort and simple modifications. The entire system with the airbag itself, the control unit, sensors and harnesses can be freely purchased, although this pleasure is not cheap.

Where to buy the entire system is chosen by the car owner himself, either in a new store, or at a dismantling site from an old car.

There is another interesting and budget option; on old Japanese Toyotas over 20 years old, an airbag was installed without sensors and an electronic control unit. Its operation is based on a purely mechanical principle; at the moment of a sharp contact with the center, the cartridge is activated and the airbag deploys. Therefore, such a pillow does not require adjustment and adaptation; all the difficulties lie in installing the steering wheel on the VAZ. And according to reviews, this device is quite reliable, despite its age.

The only negative is the large diameter of the steering wheel, which exceeds the size of the VAZ steering wheel. But the cost of such conversion is quite low, and the increase in driver safety increases several times.

Checking and replacing the engine mount

Timely replacement of the VAZ 2114 engine mount is of great practical importance. This is one of the most important components of a car engine suspension.

After all, it is with the help of these elements that reliable fastening of the engine to a non-rigid body and its depreciation are achieved. Such a replacement of the VAZ 2114 engine mount must be carried out on time, preventing the appearance of disturbing noises and knocks when crossing uneven road surfaces. Otherwise, the following malfunctions may occur:

1. The power plant, due to faulty supports, acquires excessive mobility. This may lead to deformation of the air purification filter housing upon contact with the hood. 2. A cooling system fan with faulty supports can touch the radiator grille, and, as a result, the blades become deformed and the fasteners become loose.

Car enthusiasts often ask the question, how much does a VAZ 2114 engine mount cost? This product is in the price range from 1500 to 1800 rubles.

What is required to replace the engine mount:

  • new support;
  • 2 jacks;
  • car repair stands;
  • locksmith kit;
  • polyethylene bags;
  • colored marker;
  • adhesive composition for threaded connections;
  • scrap.

Pillows always require close attention from the car enthusiast, since if they are defective or aging, they require replacement, otherwise the increased vibration impact can lead to vehicle breakdown, resulting in failure of the vehicle's transmission system

In this case, it is important to remove the weight load from the VAZ 2114 engine mounts by lifting the car. To do this you need:. To do this you need:

In this case, it is important to remove the weight load from the VAZ 2114 engine mounts by lifting the car. To do this you need:

  1. Raise the vehicle on a jack and place it on supports, then place a lifting device under the bottom of the engine crankcase.
  2. Install a wooden beam between the pallet and the vehicle lifting device to evenly redistribute the load force. Carefully lift the engine a little to remove the weight load from the power plant mountings. It is forbidden to work on a car that is hung on jacks!
  3. Visually check the engine mountings for various defects (cracks, delamination or hardening). There are cases when the rubber coating has a defect in the central part of the support.
  4. Determine the wear of the pillow plates at the point of contact with the chassis (frame) using a “mounter” or a large-size screwdriver. If there is play, remove the engine from the jack and tighten the engine mounts, followed by assembly.
  5. To prevent early obsolescence of rubber products of engine mounts, it is necessary to apply a protective component to their surface.

To replace the VAZ 2114 engine mount, the following measures must be taken:

1. Remove the negative cable from the battery terminal. 2. Raise it on a jack and place it on supports. 3. Raise the power unit on a lifting device, being careful not to touch the radiator or fan guard. 4. Loosen the bolt and remove the mounting of the cushion to the chassis. 5. Remove the through-type fasteners and the cushion.

Installation of a new VAZ 2114 engine mount is carried out in the reverse order; in this case, it is necessary to apply adhesive sealant to the threaded segment and tighten the fasteners tightly.

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 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.

When do you need to change engine airbags?

The main reason for replacing engine mounts is the natural wear and tear of the rubber part. This process is irreversible and any rubber product is susceptible to it. However, there are a number of cases when replacing a support may be necessary ahead of schedule - this is an accident or any other accidental damage.

Symptoms of faulty supports include the following:

  • Various knocks that appear when you suddenly start moving or braking. Sometimes it can occur when changing gears.
  • Vibrations that are transmitted from the engine to the body. If the level of vibrations in the cabin has increased, then it’s time to assess the condition of the supports.
  • It may happen that when replacing the timing belt, the mechanism cover will not be so easy to remove due to the fact that the engine tilts towards the mudguard. This phenomenon is associated with subsidence of the rubber part of the support.
  • Due to a sagging engine, the geometry of the CV joints is disrupted. Therefore, if you notice too rapid wear of the grenades, you need to carefully check the engine mounts.
  • Shifting the gearbox may be accompanied by a certain metal grinding noise. This suggests that due to the sagging engine, the wings have dropped lower. Accordingly, when switching, they touch other parts of the car.
  • There are cracks and other defects on the rubber parts of the support.

If you delay replacement until a later date, the engine may collapse and then repairs will become much more expensive. That is why, try to change the supports immediately after detecting malfunctions.

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.

As already mentioned, there are three rubber supports on the “fourteenth”:

Front cushion

  1. It is necessary to drive the car onto the overpass and make sure that it does not move. To do this, put the handbrake on and engage first gear.
  2. We remove the crankcase and engine protection, freeing access to the support.
  3. If the car is not new, to make work easier, all fasteners should be treated with anti-rust solution, and before assembly, all bolts should be cleaned with the same solution.
  4. Raise the engine slightly using a jack. It is recommended to place a wooden beam or board between them to prevent damage to the part. We carry out the lifting very carefully, avoiding damage to the fan housing and radiator.
  5. On the body cross member we find a long bolt connecting the bracket to the support and unscrew it.
  6. We unscrew the mounting bolts connecting the support to the engine block.
  7. We remove the damaged pillow.
  8. We install a new one and assemble everything in reverse order.

Left pillow

To replace the left airbag, you need to equip yourself with a cable.

  1. Using a cable, we hook up the gearbox and place a jack under it.
  2. If the starter is an old type (large size), remove it.
  3. Find the bolt that holds the support to the bracket and unscrew it.
  4. We remove the pillow.
  5. Install the new pillow by performing the steps in reverse order. Before firmly tightening the bolts, check that everything is in place.

Back cushion

To replace the right airbag you will also need a cable.

  1. Similar to replacing the left airbag, you need to hook up the gearbox with a cable and place a jack under it for safety.
  2. We loosen the bolts connecting the gearbox and the cushion.
  3. We also loosen the 2 nuts on the body that hold the cushion.
  4. Raise the gearbox with a jack and unscrew these 2 nuts.
  5. We unscrew the bolts from the box that secure the mountings of the pillow.
  6. Remove the rubber support.
  7. We install a new pillow, to do this we do what is written above in reverse order. Don't forget to clean off any rust before screwing in the bolts.

Purpose of engine mounts

The main purpose of engine mounts is to reduce vibrations, since without their participation all the vibrations that occur during engine operation are simply transmitted to the body, and this is very uncomfortable. And at the moment when these rubber softeners (dampers) wear out, the car ride is like a cart with a motor, intense, but very shaking.

Types of airbag malfunctions on the VAZ-2114

One of the most common types of engine mount failure is loss of elasticity.

Since this element is made of rubber, it loses its properties over time and is no longer able to fully perform its functions. This is due to the constant loads that fall on these elements along with the constant change in weather from hot to cold. From such conditions, cracks first form on the surface of the “cushion”, and then it simply begins to delaminate.

In order to prevent the destruction of rubber in time, it is necessary to inspect it in time and, if damage is detected, replace it.

So, as soon as timely dismantling and repair will allow you to avoid unpleasant problems in the future.

Operating principle

The airbag installed on the VAZ 2114 is a system consisting of:

  1. Gas generator.
  2. Bag.
  3. Shock sensors.
  4. Electronic control unit.

The bag, filled with gas and forming the pillow itself, is made of strong 0.5 mm thick nylon, which is treated with a layer of silicone for tightness.

Airbag VAZ 2114

The gas generator is a squib containing a charge of solid fuel. The charge burns out when triggered, releasing gas that fills the cushion. Sodium azide is usually used as a fuel, which, when burned, turns into a mixture of nitrogen, carbon dioxide, carbon monoxide gases, as well as water and solid powder.

The combustion process occurs quite quickly, filling the pillow in 0.03 seconds. The pressurized gas passes through a filter that allows only nitrogen to pass through. When filled, the pillow stays for about 1-2 seconds, as the gas escapes through the vent holes to avoid harm to a person.

Only front sensors are installed on the VAZ 2114, since the airbag circuit is used only for the driver. The control unit uses a two-level system that eliminates involuntary activation during emergency braking. In the event of a lack of battery charge or a power failure, the squib is activated by a capacitor, which will ensure the airbag opens.

The driver's airbag has a volume of 80 liters and, when filled, flies out at a speed of more than 300 km/h, so it can cause harm to the driver if he is not wearing a seat belt. In addition, filling the pillow is accompanied by increased noise. It should be remembered that the electronic system sensors are activated only when the vehicle ignition is turned on.

Assembly of the unit

After purchasing all the new components, you only have to do a few simple steps:

  1. Compress the spring using a puller. It must be installed in such a way as to engage at least three turns.
  2. Install rubber pads on the spring; they can be secured with tape or tape.
  3. Place the bump stop on the rod and the boot on top.
  4. Install the rod into the hole in the body and tighten the nut.
  5. Secure the lower part of the shock absorber to the rear beam by aligning the holes and inserting the bolt. Tighten the nut.

Check the tightness of all threaded connections. After a run of 50-100 km, it is recommended to re-tighten all the nuts. When replacing the rear struts of a VAZ-2115, use nuts with plastic bushings - they are much more reliable.

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.

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.

Torn engine mount: signs

Like any other part, the power plant support also has a limited service life and eventually fails. On average, airbags on modern cars are designed to last at least 100-120 thousand km, although in practice these elements may need to be replaced both earlier and much later than this period.

Usually the cause of problems is the rubber insert, which simply cracks and breaks under load. Less often, cracks appear in the metal part of the support, the installation sites of fasteners are broken, etc.

One way or another, the following symptoms usually indicate a malfunction of the engine mounts:

  1. The engine itself runs smoothly, but the driver feels a clear increase in vibrations in the body, on the steering wheel, on the gearshift knob, etc.;
  2. When you start moving from a standstill, as well as during braking, you can hear clicking or muffled knocking in the engine compartment;
  3. When driving on an uneven road, impacts are heard from the front of the car; in many cases such impacts are felt on the gearshift lever; shifting gears with a manual transmission at this moment can be difficult;

To check the engine mounts, it is not necessary to immediately go to a service station and drive the car to a stand. Usually, a fault can be identified and localized on your own, even if you do not have much experience in car repair and maintenance.

The simplest method of initial diagnosis is to rock the engine with your hands in the engine compartment, after which you can localize a torn or cracked support by knocking.

Another technique for diagnosing engine mounts is when the hood is first opened and fixed, then the car is started and jerked forward in first gear. The car moves backwards in the same way. At this time, an assistant outside monitors the vibrations of the internal combustion engine.

To carry out a more detailed check, you first need to find out in advance where exactly the supports are located on a particular model. Then the elements available for review will need to be pre-inspected. Cracks, breaks and other damage are usually visible and easily visible.

For a full visual assessment of the lower airbags, you need to be prepared for the fact that the car will need to be parked in a garage with an inspection hole, driven onto an overpass, or using a lift.

how to replace engine mount

. From this article you will learn how to replace an engine mount, as well as what subtleties and nuances should be taken into account as part of this procedure.

If a superficial diagnosis shows nothing, then the assistant should be used again. One person uses a pry bar to move the support, while the other watches for tears in the rubber insert at the very moment the support moves. It happens that some cracks are not immediately visible without rocking.

After detecting a torn engine mount, the damaged element should be replaced. It is not recommended to try to press the rubber insert out of the cylinder in order to save on spare parts, since such makeshift repairs often do not bring the desired results.

As for the replacement itself, replacing the top cushion is quite simple. The car needs to be jacked up, the old cushion removed and a new one installed.

If you have to change the lower supports, it is also important to consider that the engine goes down after removing this cushion. This means that an additional support will be required that supports the internal combustion engine, allowing you to direct the pillow and correctly secure this element

If it happens that while driving on an uneven road you hear a sound from the engine compartment, accompanied by vibration in the body, which immediately disappears as soon as you move to a flat surface, then most likely you have problems with the engine’s locking elements. Simply put, there are faults in the engine mounts.

On the VAZ-2114, the design provides for three such elements, and only one of them holds the engine, and the rest the gearbox.

The car engine is quite heavy and subject to vibration, so it must be secured against any displacement during operation. If the fastening points are rigidly connected to the body elements, they will fail very quickly, since when driving over uneven road surfaces, the fastening points will absorb significant alternating loads.

Plus, the entire body will constantly vibrate, which, in addition to discomfort for those inside the car, will also negatively affect the durability of all elements of the car.

VAZ engine cushion (support)

Purpose

Special supports, or cushions as they are also called, are used to dampen vibrations during engine operation and to securely fix it.

The name of the support as a pillow is not accidental, as it fully corresponds to its purpose. So, in Ozhegov’s explanatory dictionary, one of the meanings of the word “pillow” is something that supports something, takes on the pressure of a mechanism.

The main task of installing supports is to securely fasten and minimize sideways movement during operation.

In addition, thanks to the pillows, the power unit is isolated from all body parts, which makes the car comfortable to drive.

Depending on the car model, the engine can have from 3 to 5 airbags.

So the front and rear airbags monitor vibration at idle and when the engine reaches maximum load.

Design

The simplest support is a rubber-metal element, where a layer of rubber is placed between two steel plates. The plates have a threaded part in the form of a pin at the ends for connection with body parts. Such products can be made either integral or collapsible.

Some supports, for example, the classic VAZ 2101-07 models, also had a spring and a rubber bumper inside the cushion, which increased rigidity and softened strong impacts.

Recently, increasingly, instead of rubber, manufacturers have begun to use polyurethane, as the most wear-resistant, and metal in most cases has given way to aluminum.

On more expensive car models, more modern designs, such as hydraulic supports, are used for greater driving comfort. They consist of two chambers and a membrane between them; the chambers are filled with liquid, which, when loaded, can move from one container to another.


Electric hydraulic engine mount

Such supports can be adjusted to the operation of the power unit in any mode of operation and are capable of maximally damping any vibrations that occur, significantly increasing the degree of comfort when operating the car.

The greatest loads on the engine mountings occur when starting the engine, starting and stopping the vehicle. A faulty mount increases the stress on the engine and transmission, making them more likely to fail.

Malfunctions:

• Cracks, breaks in the filler body or steel plates;

• Deformation of the pillow;

• Peeling of rubber from metal;


New and old pillow

Signs of malfunction:

• Engine vibration;

• The motor “bounces” when starting and braking the car;

• Vibration radiating to the steering wheel, gear knob and the entire body;

• Shocks when changing gears;

• Knocks out the speed;

• Impact when planing at reverse speed;

• When driving on an uneven road, knocking noises are heard, similar to a malfunction of the chassis.

Causes of malfunction

There can be several reasons for premature pillow failure. For example, when tuning a car, shock absorbers with a stiffer characteristic and low-profile tires are installed to improve handling and change the appearance of the car. However, in this situation, the shock absorbers in the pits do not completely dampen body vibrations, which have a negative effect on all suspension elements, including the engine mounts.

Driving style. These are sudden starts and braking that provoke huge loads on the engine mounts due to a rapid shift in the center of gravity. This also includes driving over bumps on the road without slowing down.

Natural wear and tear. These are mechanical loads, temperature changes, aging of the rubber filler, which loses its elasticity.


Tired pillow

Replacement timing

On average, the power plant supports are capable of operating for about 100 thousand kilometers or more (up to 200 thousand) with moderate driving and proper monitoring of their condition.

If any signs of malfunction of the engine and gearbox mounts are detected, it is recommended to replace them without delay. At the same time, you should not purchase products from an unknown manufacturer, giving preference to the original.

Finally. Serviceable supports mean comfort and safety of movement, as well as extending the life of your power unit.
