Lifehack: car engine support (pillow) - Priora with 16 valves

The power unit of a passenger car, and in particular the Lada Priora, has a mandatory support, one of the elements of which is a pillow. It is precisely this that is necessary for attaching the heavy “engine” to the body. The engine mount itself is, although a simple but necessary special structure, made of rubber and metal, and to be more specific, it consists of a body, respectively, steel and a fairly thick cushion made of rubber.

The so-called 16-valve or 8-valve engine mount functions as a kind of vibration damper emitted by the power plant.

On the popular Lada Priora, 8-valve power units are always attached to the body by one rear and 2 side supports, and 16-valve power units by 2 side and 2 front supports, with one located on top and the other below.

Airbag malfunctions

You can tell that the airbags have become unusable by the amount of engine vibration. If it operates in normal mode, and the body begins to rattle, transmitting vibration to the steering rack, pedal block, and instrument panel, you can be sure that the reason for this is the wear of the pillows.

The greatest vibration is usually observed when the engine starts, as well as when it is turned off. When the rubber cushions are completely worn out, a knocking noise may appear caused by the contact of the engine elements and its supports. To be more convincing, start the engine, open the hood and visually inspect the engine mounts and the cushions themselves. Place your palm on the motor and feel how much it vibrates.

The causes of failure of engine mounts can be:

• deformation due to spent life, mechanical or temperature effects;
• loss of elasticity due to “aging” of rubber and temperature changes;
• delamination or cracking caused by exposure to chemically active liquids.

5.9. Replacement of power unit supports

The power unit (engine and gearbox) is mounted on two rubber cushions at the front and rear, secured through brackets on the engine and gearbox housing. These supports are designed to transfer the weight of the power unit to the body and limit its longitudinal movements. On the right and left there are supports with rods that limit the lateral movements of the power unit.

The suspension parts of the power unit are shown in Fig. 5.5. You will need: keys “13”, “15”, “17”, a jack or similar lifting mechanism. 1. Hang the front of the car on supports or lift the car on a lift. 2. Remove the engine splash guard (see “Removing and installing the engine splash guard”).

11. Install the bracket and cushion of the rear support of the power unit in the reverse order of removal.

18. To replace the right support bracket, which is also a generator bracket, remove the generator (see “Removing and installing the generator”, page 212), unscrew the three bolts securing the bracket to the cylinder block with a 15mm socket wrench...

19. ...and remove the bracket. 20. Install the parts in the reverse order of removal.

23. Install the rod in the reverse order of removal.

Removing the left support

We install an adjustable stop under the gearbox.

Using a 15mm socket with an extension, loosen the tightening of the upper tension nut of the support cushion.

From the bottom of the car, using a 17" socket with an extension, unscrew the nut securing the left power unit support to the gearbox bracket (for clarity, the left mudguard of the engine compartment has been removed)... ...and remove the washer.

Using a 13mm socket with an extension, unscrew the two bolts securing the support to the body.

Remove the left support. To disassemble the support, finally unscrew the upper coupling nut of the support cushion.

Parts of the left support: 1 - upper nut; 2 - upper limiter; 3 - pillow; 4 - lower limiter; 5 — hairpin; 6 — washer; 7 — lower nut The upper support stop has two flats. When installing the support...

...the flanges of the cushion clip should face up. We assemble the left support without fully tightening the upper coupling nut, after which we install the left support in the reverse order. In this case, the flats on the stud, preventing it from turning, should be located in the groove of the gearbox bracket. When final tightening the upper coupling nut, it is necessary to ensure that the flats of the upper stop are located parallel to the axis of the support mounting holes.

How to replace the engine mount

Due to wear and tear on your vehicle, it may be necessary to replace your engine mounts at some point. The number of engine mounts depends on the vehicle. Follow these steps to successfully replace a faulty motor mount.

Step 2 - Attachment

The engine bridge may suffer from wear and tear associated with starting the vehicle. Examine your engine and note the fastenings that need to be replaced.

Step 3 - Components

Look at the fasteners as well as other components. Typically, the bolts holding the mount in place are also affected. You will need to remove them to begin the installation.

Step 4 - Battery

Once we've installed the mounts and components, it's time to turn your attention to the battery. The black wire or negative cable must be disconnected from the battery

Step 5 - Raising the Vehicle

For better access you need to raise the car. Use a jack to raise the car and place jack stands to support the car.

Step 7 - Safe Storage

It is necessary to remember the unscrewed components what goes where, this will save a lot of time when reinstalling.

Step 8 - Engine Support

When replacing the mount, you may put pressure on other parts of the brackets. This additional pressure may damage some parts. Therefore, it is recommended to support the side part with a socket. The jack must be placed close to the anchor point.

Step 9 - Removing the Bolts

Learn how to remove all the bolts from the mount you want to replace. Some bolts can be easily removed from the bottom. Depending on how the assembly is mounted, sometimes a screwdriver will not be useful. You will need to use a wrench.

Step 12 - Final Stage

Return the vehicle to ground level. Connect the black wire to the battery.

You have successfully replaced the engine mount on your car. Now you can take your car for a test drive

Prices and articles

Below is a table of prices and article numbers for Lada Priora engine mounts depending on the model, type and manufacturer.

Replacing the optional top cushion:

This cushion is also not difficult to remove, it is attached in the same way to one bolt with a cage nut (This nut is indicated by a green arrow in the small photo and most importantly, when you unscrew the bolt, do not lose this nut, be sure to hold it) and to another bolt , but only at the end of which a regular nut is screwed in (the approximate location of this nut is indicated by a blue arrow, and its bolt is shown in red), when these two bolts are removed, you can remove the upper support and put a new one in its place.

Additional video clip: If you suddenly want to understand what kind of airbags are generally installed on 16 valve cars of the tenth family and the Priora family, and also if you suddenly wonder how they can be distinguished from each other, then in this case, watch the video clip just below :

Do-it-yourself replacement of engine mount cushions on a Priora

On an 8-valve engine:

• The car must be prepared for repair work; for this purpose it is placed on a flat surface; it is imperative to place stops under the rear wheels and remove the protection of the power unit.
• Cl. 13” remove the bolt holding the generator belt tensioner. We remove the belt.
• We install a jack under the “engine” of the LADA Priora, not forgetting to place a thick board under it, or a regular beam will do. The power unit must be raised so that there is no load on the supports.
• Cl. 15” unscrew the nut of the so-called central fastening directly to the pillow on the right.
• We remove the cl. 13” bolts securing the pillow on the bracket.
• Unscrew the plug. 17” 3 bolts that secure the bracket to the car side member. You can find these bolts on the side of the right arch directly below.
• At this stage, we remove the bracket and replace the old pillow with a new one.
• In the reverse order, we put everything back in its place in exactly the same order.
• Next we jack up the gearbox.
• Cl. 15” unscrew the nut of the so-called central fastening on the left cushion.
• Cl. 13” unscrew the 2 existing bolts securing the supports we are considering.
• We replace the pillow with a new one and assemble everything, observing the sequence in reverse order.
• Cl. at 17”, unscrew the 2nd nuts, they are the ones that secure the support cushion to the body, then the 2nd nuts on the side where the cushion is attached to the gearbox.
• It's time to remove the rear support.
• Cl. 19” unscrew the only nut securing the support pad to the bracket. We replace the pillow with a new one, then collect it in the reverse order.

Replacement work on a 16 valve engine:

The 16 valves located on the side of the engine mount on the LADA Priora are removed and replaced in the same way as on 8-valve engines. In order to replace the pillow from below, you need to work from underneath.

• Cl. 15” remove the only bolt that secures the so-called lower support bar, which is located in front, to the suspension cross member, also located in front.
• Using a pair of 15” wrenches at once, unscrew the nut securing the metal. support to the motor bracket. We remove the bolt with ease.
• We remove the old support, change the pillow, or, if desired/necessary, the entire structure.
• And, don’t forget to collect everything in the reverse order of the given one.
• Under the hood, you need to unscrew the bolt connecting the upper front support and part of the body. We use cl. by 17”, and it is recommended to hold the nut by hand.
• We take out the nut and bolt.
• Cl. 15” unscrew the existing bolt connecting the upper front support and the power device bracket. We remove the nut and, accordingly, do not forget about the bolt.
• We then carry out the now familiar replacement and assemble everything, following the reverse instructions.

When the entire 16-valve engine mount has been replaced, or even if the engine has 8 valves, you need to start the engine and check if vibration is present. If the engine mount is installed correctly and properly secured, then vibration should be completely absent or minimal; detailed instructions can be found here.

Removing the rear support

Using a 15mm spanner, unscrew the nut of the bolt securing the rear support to the engine bracket, holding the bolt with a wrench of the same size (for clarity, the rough road sensor with bracket and the solenoid valve for purge the canister have been removed). We take out the bolt.

Using a 15mm socket, unscrew the bolt securing the rear support to the body (the bolt is screwed into a cage nut installed in a closed body box).

...and remove the support. It is more convenient to start the assembly by installing the bolt securing the support to the body, since it is more convenient to center the cage nut while the support can move. Do not tighten the bolt. Then, aligning the holes in the support and in the engine bracket, insert the bolt. Tighten the nut of the bolt securing the support to the engine bracket and the bolt securing the support to the body.

1. Installation of rear additional engine support from 8 cl. from VAZ 2110 to Lada Priora

We will talk about the rear additional engine support from the 8 valve 2110. The topic is not new, but mine will differ from many others in its effect. But first, about the installation.

For installation you need the following kit or set of spare parts:

— 2 studs M10×28×1.25; — 2 M10 self-locking nuts + 2 regular nuts to screw in the studs; — 2 washers for M10 bolt; — 2 bolts М12×75×1.25; — 2 or 4 washers for M12 bolt; — 2 nuts M12×1.25 self-locking; — 1 rear engine mount from 8 cl. 2110.

Installation is carried out in the holes already prepared in the body for the support itself, since the body of the Priora is based on 2110 and nothing has changed since 1997 (. There are also ready-made holes in the gearbox for these purposes, so we screw the studs into the holes in the body , we put a support on them, fasten them to the box with long bolts, tighten everything, everything is ready.

As many people write, the car does not twitch when releasing the gas sharply at speeds 1, 2, 3, the gearbox lever does not twitch, there are only positives, the only thing is a little noticeable vibration, but this is a trifle, if no one wrote about it, they would not have noticed (many people write this). That's what I thought too, but... BUT everything turned out wrong. It seemed like there was something I liked on the first day of driving, as if the push when pressing the gas to 1st and suddenly releasing the pedal suddenly disappeared, but after driving for about five days I began to understand that it was not needed here. Still, to a large extent, it is not just put on priority list. A decent amount of vibration appeared not only in the gearshift knob, but throughout the entire body, and when you turn on the air conditioning, everything vibrates. The twitching that I wrote about earlier almost remained a little different, but still. There was also a feeling that when you want to accelerate a little sharply, something seems to be holding you by the ass and everything is stupid, without support there was no such feeling (please don’t write about the fact that the firmware needs to be changed, etc., I know , maybe someday I’ll replace it if desired). Actually, I took it off, now I just need to tighten the drawstring, and everything is fine without it.

Replacing the upper engine mount of Priora

One experienced person, with a quick glance under the hood of my car, immediately pointed out to me that the upper engine mount was worn out and needed to be replaced (many thanks to him for the advice!). You don't need a lot of experience to replace the top support. There is no need to jack the car. So I decided to do everything myself. Everything turned out to be not as easy and simple as it was written in the Murzilka, but 40 minutes of quiet swearing and perseverance did their job - the support was replaced. I’ll say right away that when starting off, significant vibrations were previously felt (the car seemed to be shaking violently), after installing the new support, 90% of those vibrations went away. I'm sure the other supports need to be replaced too, but that's still to come.

I bought a “cooperative” (that’s what the seller said) upper support in the store for 490 rubles. I compared the new “cooperative” one with the new “native” one in the store - the quality of the rubber bands is better, the metal is galvanized, it looks more solid or something... but 180 rubles more expensive.

The conclusion was clear. I haven’t considered enhanced options yet, but maybe I’ll try in the future.

The installation has begun. It turned out that I did not have 15 and 16mm keys. I had to go buy it. The old support in its place looked tired...

I sprayed the fastening points of the nuts with WD40 to make it easier to unscrew. After 10 minutes I sprayed again.

The mount to the body turned quickly, but the mount to the engine took some work.

The fastening to the body turned quickly

The mount to the engine held on for a long time...

On the one hand, I inserted a ratchet with a 15mm head (pulled towards myself). On the other hand, I threw a wrench on 15 (fixed it in place). About 10 minutes of rocking and twitching did the job - the bolt and nut were twisted. We take out the long bolt.

This is where the dancing began with the bolt that secures the support to the body. The bolt rotates, but does not come out. I twisted and twisted for about 10 minutes until I began to feel the entire fastening structure from all sides. It turned out that the square “nut” into which the bolt is screwed rotates along with the bolt, but it is not so easy to get to it. A solution was found - I inserted a screwdriver from below into the place where this nut was supposed to be.

This square nut rested against the screwdriver and stopped turning. The bolt came out quickly.

The rubber in the old support was all torn and clearly did not perform its functions.

I installed the new support quickly.

The new support and the old support are side by side.

The air conditioner pipes created some inconvenience during dismantling, but it was tolerable. The general feeling after the replacement is positive. I advise anyone who has strange vibrations to pay attention to the engine mounts.

The engine and gearbox of a Priora car are mounted on two rubber cushions at the front and rear, secured through brackets. This helps in transferring its weight to the body, to avoid longitudinal movements. At the same time, left and right supports are used to avoid lateral vibration.

Replacement of cushions and supports must be carried out in case of damage, as well as in case of excessive wear, which can be easily determined by the characteristic vibration when accelerating and braking the car. You can also determine a violation of integrity by feeling it with your hands. Be sure to take the necessary safety precautions when making repairs to avoid injury or damage to your vehicle.

— Keys for 13, 15, 17

1. First you need to hang the front of the car using a jack or lift it on a lift.
2. Disconnect and remove the engine splash guard.
3. Before removing the rear support cushion, make sure that the jack or hydraulic strut is firmly positioned under the crankcase.

The top and bottom stops are shaped differently, so be careful to install them correctly.

When installing the airbag, orient its conical part upwards and the cutout towards the front of the car.

The pillow fastening pin must be installed with the flange down.

Steps to replace the left and right support rods

To replace the right support rod, you need to unscrew the two bolts that secure it - after that we can freely remove it and replace it. It may be necessary to replace the right support bracket itself (also known as the generator bracket). To make a replacement, unscrew the three bolts that secure the bracket to the engine, then remove it.

To replace the left support, remove the nuts and bolts, then remove it, then install it in the reverse order of removal. At this point the repair is complete and testing can be carried out.

The left engine mount cushion of the new model 2110-1001240-L of the Future Technologies brand has recently been installed on all LADA Priora cars on the VAZ assembly line.

Developed and produced using the most modern technologies under the control of Trelleborg AB (Sweden).

“Prior” engine mount cushions of a new type were introduced at VAZ to reduce noise and vibrations transmitted from the engine to the car body. This effect is achieved due to a more advanced design of the supports themselves, as well as the use of a special highly elastic rubber mixture.

Any owner of a VAZ of the “tenth” family or an early LADA Priora can buy engine mounts from “Technologies of the Future” to install on their car instead of the old ones. This will significantly improve acoustic and vibration comfort, and will also eliminate the need to monitor the condition of engine mounts for a long time.

What is a Priora airbag?

Typically, this Prior safety element will work in the event of a frontal impact or an angular impact, which occurs at an angle of no more than 30° at a higher required speed.

This indicator is also important: everything will depend on how rigid the object with which the collision occurs. If it is capable of deformation, then the system will come into action at a speed that exceeds 25 km/h, only with frontal interaction.

The so-called airbag is a whole coherent system that has the following elements:

• the gas generator itself;
• a special label with a barcode;
• a housing in which the folded inflatable pillow will be placed;
• fasteners; connector with fuse and igniter at the gas generator part;
• facing cover.

The essence of the action of the gas-generating element located in the pillow is as follows:

There are two types of gas generators:

The first will consist of a body that will be filled with a solid pyrotechnic substance and the igniter itself. As for the second, it will consist of a casing material containing compressed gas of inert origin, as well as all the components already listed above.

1. When struck, an electrical signal will be generated.
2. The electrical resistance will heat up and ignite the pyrotechnic substance.
3. The rest of the mass ignites.

It is very important that the facing cover covering the airbag itself is intact. The purpose of this part in the Prior is to cover the folded element near the pillow during normal times, but it will rupture during gas filling at the moment of collision.

This will happen along the structural seam - it is located along the back side on the cover itself.

This will happen along the structural seam - it is located along the back side on the cover itself.

• sensor responsible for acceleration;
• an electronic circuit that generates signals entering the control.

The control unit itself is designed to convert and process information that comes directly from the sensor responsible for acceleration. In the future, it will generate a signal of electrical origin sent to the fuse.

The airbag responsible for safety in the Priora must be coordinated in its future operation with the belt. When the person driving is not wearing a seat belt, it simply will not work.

1. At the moment of impact, the pillow will inflate very quickly and press the person to the seat with great force.
2. In the case when the driver is not fastened, the body involuntarily swings forward and is met with a huge blow from the airbag. This is fraught with additional major injuries.

The status of the airbag on the Priora is regulated by a special sensor located on the dashboard. The light will indicate each existing fault. If it lights up, it helps to monitor the airbag data, as well as keep these systems in working order, which will be the key to saving the driver’s life on the road.

What problems do pillows have?

How can the owner of a Lada Priora understand that the engine mount, and its main element - the cushion, have already completely become unusable? When the engine operates in its usual mode, the body begins to rattle quite noticeably, plus vibration, which cannot be ignored, is transmitted to the steering rack, as well as the dashboard, and even to the pedal block. If you notice this, then know for sure that it is the pillows that have worn out and will certainly need replacement.

As a rule, a slight vibration is present when the engine starts, and it is felt when it is completely turned off. When the pillows are completely worn out, a knocking sound often begins to be heard, and it appears due to the contact of the motor with the support.

In order to be completely sure that this is where the problem lies, you need to open the engine compartment and inspect the supports and, without exception, all the pillows. You can feel the force of vibration if you place your palm on the “engine”.

What could be the reasons why the support cushions we are considering fail:

• Due to fairly rapid temperature changes and the natural aging of rubber, cushions lose their elasticity.
• Trace factors influence: temperature/mechanical stress or it happens that deformation is inevitable due to the spent resource
• All kinds of chemical liquids also act, and cracking and even delamination occurs.

Priora front strut supports, their features

The front shock absorber elements of front-wheel drive cars are not only a device that compensates for unpleasant road irregularities, but also a part of the turning mechanism. This makes adjustments to the design of these supports. Due to the fact that the strut is essentially a lever for turning the caliper, a special bearing is built into the upper support. That's what it's called - support. This allows you to reduce wear both on the support cup itself and on the shock absorber rod that goes into it. The presence of this bearing ensures the stability of the vehicle's steering.

The malfunction of this part is expressed in a decrease in the car's controllability and the appearance of extraneous sounds when the Priora hits any obstacle.

Description of auto parts

The support bearing is a structural element of the strut . It ensures the mobility of the connection between the shock absorber and the body part. Acts as a type of rolling bearing.

The main reason for the failure of this part is the entry of debris and dirt into the structure. Such situations are not uncommon in low-quality road conditions.

A dirty and worn mechanism leads to a characteristic knocking and crunching sound when driving over obstacles and when turning the steering wheel. You cannot drive with a faulty support bearing. This is dangerous to the health and life of the driver and passengers.

Replacing the right damper support

Before changing the right engine mount of a VAZ 2110 car following the video example, you should install wheel chocks and also disconnect the negative terminal from the battery. The further process is carried out according to the following scheme:

• Loosen the generator fasteners with a 13mm wrench and remove the belt drive.
• Loosen the tensioner bolt.
• Jack up the right side of the car.
• Using a 15mm wrench, unscrew the nut securing the support.
• Using a 13mm wrench, unscrew the two bolts securing the support to the bracket.
• Using a 17mm socket, unscrew the three bolts securing the bracket to the right side member.
• Remove the bracket and install the new support in the reverse order.

The appearance of sound, play and creaking

Replacing the backstage cushion

Generally speaking, the appearance of sound in the wings indicates either wear or the initial low quality of the cushion, and both options are essentially equivalent, since there is only one way out - replacing the wing cushion of the VAZ 2110. Many VAZ cars, due to the structural features of the design, often have the support is, to put it mildly, not of high quality. This fact becomes obvious when the car is not driving on a level surface. The sound is so noticeable that it becomes noticeable even to the driver who is in relative sound isolation.

Note: If you hear a sound in your car that was not there before, you should visit a technical service department or your own garage as soon as possible to determine the cause of the defect. Since if the defect is not identified immediately, the economic costs will be many times higher. Because the best way to fight is prevention in the first place.

Installing an additional gearbox cushion

The Priora already has the holes necessary to install this pillow, so in addition to the spare part itself with article number 2110-1001280, you will only need fasteners:

• 2 bolts M12x75.
• 2 self-locking nuts M12.
• 4 washers for M12 bolts.
• 2 bolts M10x30 with a thread pitch of 1.25 (for some cars a thread pitch of 1.5 is suitable).
• 2 engravers for M10 bolts. 8 wide washers for M10 (can be replaced with a smaller number when using thick washers, for example, from the cylinder head).

The replacement technology itself

• The part is attached to the gearbox bracket using M12 bolts with self-locking nuts.
• The washers are placed under the bolt head and under the nut.
• M10 bolts are screwed into the body. Between it and the rod body, you need to place washers so that the rubber rod does not touch the body.

The good condition of the Priora engine mounts is the key to comfortable movement. At the same time, if you have a suitable tool, replacing components will not be difficult.

Required tool:

• Ratchet with 13, 15, 17mm heads. Head Torx E10;
• Open-end or socket wrenches 13, 15, 17 mm;
• Jack;
• Part of a wooden board;

Replacing the right support

If the car has a crankcase protection installed, it must be removed.

We jack the engine into the crankcase, placing the support through a wooden board.

Unscrew the central nut securing the support to the engine bracket.

Unscrew the fastenings of the support to the body.

Lower the engine slightly with a jack. This is necessary for easier dismantling of the unscrewed support.

Install the new support in reverse order

Replacing the left support

Replacing the left support is done in the same way as the right one, only the jack must be installed under the gearbox. The emphasis must be made through a wooden lining.

Replacing guitars

Replacing guitars is quite simple and effortless.

Using a 15 mm wrench, unscrew the bolt securing the guitar to the car body and remove it.

Using a 15 mm wrench, unscrew the bolt securing the guitar to the engine bracket and remove it, and then the support itself.

Install the new support in reverse order.

Replacing the lower guitar follows similar instructions.

Tightening guitars must be done with the engine running.

Replacing the lower support on 8-valve internal combustion engines

Work on replacing the lower support on 8-valve engines must be carried out from the inspection hole.

We unscrew the 2 nuts securing the rubber part of the cushion, which is attached to the car body.

Unscrew the two bolts securing the cushion to the gearbox housing and remove the cushion.

Installation is carried out in reverse order.

Types of supports

The Lada Priora has 4 airbags installed on the left and right of the engine, as well as in the front and rear. It should be noted that only engines with 16 valves have 4 supports, while in an 8-valve engine there are only 3 supports.

Right

The right (upper) support is located near the gas distribution mechanism (GRM). Designed to connect the engine to the car body via rubber, to cushion it and dampen vibrations. This support also limits the longitudinal movement of the engine in the engine compartment.

Left

The left support (lower) is installed between the gearbox and the car body. It serves in the same way as the right one to dampen engine vibrations during its operation, as well as to limit its longitudinal movements during movement or work.

Top bar (guitar)

The top support is shaped like a guitar, also called a rod. This support is designed to fix the engine and prevent its lateral movements. Made from metal and rubber. This pillow was produced in several versions from a metal body (on new Prior models) and metal (on older versions).

The upper guitar is located near the right glass of the stand near the support bearing. It is bolted to the glass and on the other side to the engine bracket.

Lower rod

The lower guitar has the same structure as the upper one. It should be noted that the upper and lower supports are interchangeable with each other.

A lower support is installed under the power steering or air conditioning pump. Attach to the beam and on the other side to the engine bracket.

8-valve gearbox support

This support is installed only on 8-valve engines. Attached under the bottom of the car and to the gearbox housing. This support replaces two guitar supports.

Quite often, in order to more reliably fix the internal combustion engine in the engine compartment, such a support, as an additional one, is installed on 16-valve engines.

Characteristic

What is this item? An engine mount is a gasket between body elements and the power unit. This is installed on all cars without exception. On Soviet Zhiguli cars, the cushion was a durable piece of rubber with fasteners on both sides. On more modern “nines” and “eights” (and subsequently all VAZs with a front-wheel drive layout) full-fledged rubber-metal supports were installed.

So, the power unit was mounted on four pillows. Two of them are on the gearbox, and the rest are on the engine. To avoid unnecessary loads, the box and motor are rigidly fixed. Any distortion leads to a change in the geometry of the input shaft. As a result, all the vibration is strongly transmitted to the gearbox lever and the transmission itself.

Where are the pillows? This element is installed on the engine from several sides:

• Front cushion. Attached to the front beam of the power unit.
• Back cushion. Installed to the front subframe. Located in the bottom area.
• Right support. It is located on top, near the front side member of the body.

Also note that not all vehicles have a rear support. This function is performed by the gearbox itself.

In this case, it is attached closely to the motor. The pillows themselves are made in different shapes. They are often an aluminum or steel cylinder with a silent block inside. To secure it to the body, a so-called “paw” is used. It also has a rubber spacer. This is exactly how modern engine mounts are designed. Symptoms, how to diagnose a part, what affects wear - we will consider in the course of this article.
