Rear engine mount VAZ 2109

On VAZ-2109 cars, only one engine mount is used, the other two are installed on the gearbox. With the help of these simple devices, made of metal and rubber, vibration is eliminated and their level is significantly reduced. These vibrations come from the engine and are transmitted to the body.

Any motorist can make the replacement with his own hands. No difficulties arise during the work. Replacing airbags can significantly increase the service life of both the car itself and its individual components. And the most important thing is that you will get rid of various kinds of noise and vibrations that arise during engine operation.

Features of the pillows used

There are several nuances that you should know about the supports in general, as well as about the engine mounts used on the VAZ 2109 model.

When developing the design of supports that serve to reduce engine vibrations, manufacturers take into account the loads absorbed by the supports;
These elements are under constant influence of loads, the magnitude of which varies;
One constant load is the weight of the engine. But when the car starts, another load arises;
When the car moves in reverse, the supports take on negative forces;
When sharply accelerating or braking, when a wheel hits a pothole, or when hitting an obstacle, these same negative forces arise. The front, rear and side engine mounts are responsible for extinguishing them;
To make cushions for the VAZ 2109, special natural rubber, high-grade SKI-3 rubber is used. In addition to rubber components, the supports include steel elements and heavy-duty adhesive;
The VAZ 2109 engine mounts are capable of withstanding temperature loads in the range from -40 to +70 degrees Celsius.

In order for the pillows to meet all the requirements for them, experts recommend choosing products from the manufacturer or companies that were recommended by the VAZ 2109 manufacturer.

Factors affecting the resource

The price of VAZ-2109 engine mounts is about 500 rubles. Most experts recommend choosing only products that are recommended by the car manufacturer. But there are several factors that affect the resource of these elements:

Natural production. All elements, including pillows, have a maximum service life. And hardly anyone can surpass him. They are not able to develop a full resource for reasons that will be discussed below.
VAZ-2109 cars experience very high mechanical loads when driving on uneven roads, colliding with curbs, etc. And this significantly reduces the service life of the engine mounts.

What influences the replacement

There are two main factors that force motorists to replace airbags.

Natural wear and tear. Each pillow has its own service life, exceeding which is very rare. Often they don’t work it out for the second reason.
Mechanical impacts leading to breakdowns. These are our roads, potholes, accidents, collisions with manholes, etc.

When replacement is required

There are several factors you should know about replacing engine components.

Situation

Peculiarities

If you feel vibration in the body, you should definitely check the condition of the supports. This effect can be caused by various reasons, but pillows are one of the main

Replacing the timing belt

When replacing a belt, removing its cover can be very difficult, since the engine is almost tightly pressed to the right mudguard of the front wheel. You have to remove the pillow in order to fully carry out repairs.

The engine sags, loads the CV joints

Due to the impact of the engine weight on CV joints, their geometry changes, which leads to a significant reduction in the service life of the elements. The resource is reduced, it is necessary to carry out replacements ahead of schedule

There is a knocking noise in the backstage area

It may be barely noticeable. But its presence indicates that the engine has sagged. Consequently, the supports do not work properly and need to be replaced

If you do not replace the supports in a timely manner, this will lead to more serious consequences and expensive repair of the breakdown. Therefore, it is better to replace the pillows when primary signs of wear are detected. To do this, we additionally recommend periodic inspection of the unit.

Replacement

Now we move on to replacing elements. Doing it yourself or contacting a car service is purely your personal decision.

For the VAZ 2109, the use of three supports is provided:

Front;
Rear;
Left side.

The replacement of each of them should be discussed separately, since the processes differ from each other.

Replacing the rear cushion

Find a suitable place to carry out repairs. You will need a pit or overpass.
Place the car there, secure it with stops, and put the car on the handbrake.
Disconnect the negative terminal from the car battery.
Using a 17mm spanner, unscrew the nut that holds the cushion to the body.
Using a 17 socket, remove the mounting nuts of the support bracket to the gearbox. There are 3 of them in total.
Remove all the bolts and remove the old engine mount.
Install a new motor element and reassemble the unit.

Dismantling works

Side left pillow

Left element

Provide yourself with free access to the bottom of your VAZ 2109.
Secure the vehicle with jack stands and the handbrake.
Disconnect the minus from the battery.
Remove the left engine splash guard.
Using a 17mm spanner, remove the nut that holds the cushion to the body.
Using a 17 socket, unscrew the 3 mounting nuts of the support bracket, removing them from the gearbox.
After removing the mounting bolts, replace the worn engine mount with a new one.
Carry out the reassembly procedure. Stick to strict consistency.

Replacing the front airbag

Here, follow all the same conditions that were relevant for previous works. That is, drive the car into a pit, place supports and turn off the power to the car by removing the negative terminal from the battery.

Using a 17mm spanner, remove the nut holding the cushion to the body.
Using a 17mm wrench, remove the 4 fastening nuts securing the airbag to the engine.
Remove the rubber element from the eyelet.
Place a new support in place of the old unit.
Reassemble the unit.

When replacing engine mounts, be sure to make sure that the new mounts meet the quality and size requirements. It is also recommended to thoroughly clean the seats before installing a new element, which will extend the service life of the new motor mounts.

Replacement does not require special skills, special tools or special conditions. Therefore, VAZ 2109 owners often change the pillows with their own hands. But if you are not confident in your abilities, contact a trusted car service center.

But the devil is not as terrible as he is painted. First, let's look at what the rear pillar actually consists of. Cushions under the car's engine will help reduce the force of vibration or even eliminate these disturbances that may occur on the body of the VAZ 2109. The material for their manufacture is rubber, and the elements are also used to reduce noise, which can be caused by a running engine. It is good for any car owner to be able to do this work with their own hands.

Features of engine mounts for a VAZ 2109 car

When developing cushion designs to reduce vibrations of the power unit, manufacturers are guided by the magnitude of the loads that the supports perceive. These devices constantly perceive loads that change periodically. One operates when the car is stationary - the weight of the unit; at start - the other. When the car moves backwards, the airbags absorb negative forces.

Sudden acceleration, unexpected braking, encountering an obstacle or hitting a pothole cause negative forces to occur. They must be extinguished by the installed rear, front and side supports. To manufacture the elements, natural rubber, high-grade rubber of the SKI-3 brand, high-quality steel and special glue are used. Engine mounts can withstand from (-45) to (+70) degrees Celsius.

This indicates that for the VAZ 2109, the side left and right, front and rear engine mounts should be used only those manufactured by the manufacturer. In this case, they will meet all the requirements of manufacturing technology and are supplied to specialized stores. Car owners must purchase products from reliable suppliers who have proven themselves and have good reviews from customers.

Factors influencing the replacement of pillows for a VAZ 2109 engine

All manufactured products have a warranty period, after which they may fail. This also applies to the supports for the power unit of the VAZ 2109 car. Natural aging of rubber occurs, it can crack from long-term use. In addition, there are also mechanical breakdowns associated with the consequences of an accident, an unexpected collision with an obstacle, an encounter with a sewer hatch along the way, and many other reasons.

What you need to know about engine mounts

The strength of the pillows must be sufficient, since they are subject to loads of various magnitudes and directions. The mass of the engine always acts on the body, regardless of whether the car is moving or standing still. During movement forward or backward, loads arise that are maximum in magnitude at the initial moment of time.

When cornering, the body experiences a centrifugal type of load, especially after leveling the body, when the engine itself tends to continue moving in a circle. And all these forces must be experienced by the car body and pillows. It is necessary to carry out regular inspection for defects. And if the VAZ 2109 engine mounts have obvious damage (cracks, deformations), it is necessary to replace them.

Hitting a bump or a hole, sudden acceleration and braking of a car, hitting an obstacle - all this causes the appearance of forces. Rubber-metal supports serve to dampen them. Cushions are made from rubber, high quality steel, premium rubber type SKI-3, and glue. Withstands temperature changes in the range -45..+70ºС.

You need to pay attention to the fact that the manufacturer (AvtoVAZ) does not produce spare parts! This is a misconception of many motorists. AvtoVAZ produces only cars. And all spare parts and components are supplied to the assembly line by hundreds of manufacturers. And when choosing pillows, your task is to find exactly the spare part from the manufacturer that supplies the AvtoVAZ conveyor. But the engine mount of a VAZ 2109 car may be from a different manufacturer; tuning elements are often on sale - reinforced and more reliable.

When do you need to change engine mounts on a VAZ 2109?

— Body vibrations. — Knocking that occurs when the car starts or brakes, difficult gear shifting or unexpected acceleration. — Replacing the timing belt is accompanied by great difficulties. This is due to the fact that a sagging engine “approaches” the right mudguard almost closely, and it may interfere with removing the timing belt cover, and servicing the engine will be difficult. - Strong sagging of the unit increases the load on the CV joints. The geometry of the work may change on them, which will reduce the service life of the structures. - The appearance of a barely perceptible knock in the backstage area. This occurs due to engine sagging. - In this case, the gearbox slider may begin to touch the outer surface of the anti-roll bar. - In the case when the replacement of the engine mount on a VAZ 2109 is not carried out in a timely manner, the cost of further repairs will increase significantly.

How to change engine mounts yourself

If the vibrations of the engine, even a new, serviceable one, were transmitted into the car interior, the driver would probably be very unpleasant. Fortunately, special rubber linings at the junction of the piston unit with the car body save you from this.

But not only do they protect the people in the car from vibrations; the underlay structures save the piston unit itself from the effects of uneven road surfaces. These elements themselves consist of rubber stands, metal parts and threaded fasteners. They break due to natural factors, such as:

This is how the right engine mount is replaced. Let's look at updating the underlay structure at the back of the engine using another VAZ brand as an example.

Replacing pillows on a VAZ 2114 resembles the process on a “ten”. In any case, the tools used are similar:

This is how it is done.

It turns out that, in general terms, work is carried out in a similar way on all motor stands. Replacing the rear engine mount on a VAZ 2109 occurs in exactly the same way. The change at Priora is accompanied by the removal of the standard engine mudguard. Otherwise, the operation is the same as replacing engine mounts on a VAZ 2110.

What to do with foreign car engines

Now let’s determine how to replace a defective airbag in a Ford Focus 2. In this car, the entire support assembly is non-separable. To work you will need:

When reinstalling the right part, the steps are as follows.

This is how the Ford Focus airbags are being replaced. It is easy to see that the process does not cause any particular difficulties. Mazda 3 repairs are carried out in a similar way. If this is a replacement for the right defective airbag, then you will also have to remove the expansion tank. Next, let’s move our gaze to other foreign cars. Replacing any engine mount on a Volkswagen Passat B3 is carried out according to a scenario similar to those already described. By the way, this car's support brackets are assembled with small shock absorbers. We will prepare the following accessories for work:

We are replacing a broken rear airbag.

That's all. Let's add that there are also foreign cars that have 4 supports. For example, Toyota Ipsum. Moreover, changing the engine mounts at Ipsum is done like this: the right one is changed completely, and for the other three, only the cartridge is reinstalled. To change the left engine mount on a Chevrolet Lanos, you need to support the side of the gearbox closest to the wheel with a jack. Otherwise, everything is done without additional dismantling of any components.

Cost of the described repair procedure

From what has been described, it is noticeable that this operation, although dirty work, is not labor intensive. The cost (on average) of work in Russia is indicated in the table below.

City	Cost for 1 piece.
Moscow	900 rub.
St. Petersburg	900 rub.
Ekaterinburg	800 rub.
Samara	700 rub.

Now look at the law on tuning for SUVs 2022 and how the timing chain is replaced.

Here are the prices for the operation of replacing engine mounts on popular foreign cars, and with an average complexity of repair. For VAZ the value will be less than thirty percent.

In general, we examined different options for repair work in relation to a wide variety of machines. All the information provided should help car enthusiasts decide: either do everything themselves, or go to the experts.

Rules for replacing VAZ 2109 engine mounts

In a VAZ 2109 car, the engine is mounted on three supports: the right one, which is mounted on the engine bracket, the left and rear ones, which are fixed on the gearbox housing brackets. The instructions call for replacing the side airbag with the mudguard removed.

To work you will need:

- New side cushion. - Set of socket heads. - Hoist or jack. - Spanners. - Wrench. - Ratchet. - Rust remover, if necessary.

Work order:

Tip: Disassembling the unit should begin by removing rust from all fastening units, which will help disassemble these units. You need to remove the mudguard. Use a 17 mm spanner to unscrew the nut that secures the support to the body. Tip: When unscrewing the bolt, it must be kept from turning in the same way with a wrench. The bolt is pulled out. The three nuts securing the support bracket on the gearbox are unscrewed with a “17” head, as shown in the photo. The support is removed. After replacing the cushion on a VAZ 2109, the assembly must be performed in the reverse order. How to correctly replace the engine mounting VAZ 2109 can be seen on video.

Replacing the front airbag yourself

There is no need to place the car on a lift or inspection hole; all work is carried out on a flat surface. But this is the case if only the front engine mount of the VAZ 2109 is changed. In fact, there is only one, the other two are fixed to the gearbox. You will need the following parts and tools:

new front airbag VAZ 2109;
socket heads, ratchet and wrench;
set of spanners;
jack and supports;
penetrating lubricant such as WD-40;
lubricant type Litol-24, CV joint.

Ways to increase the rigidity of engine fixation on the body of a VAZ 2109

To prevent the VAZ 2109 cushion from being replaced frequently, and to increase the rigidity of the power unit, instead of the standard support, a more advanced part is installed, which has a rigid body and a rubber part inside.

Minimize the movement of the motor when braking, hitting bumps on the roads, or abruptly starting the car. With its help, you can avoid self-switching off the transmission. Increase the resource in the exhaust system and drive the drive wheels. Improve the design of the engine compartment. You can increase the rigidity of the motor by installing an additional fourth support . Its purpose is to connect the clutch housing to the cross member of the front suspension of the VAZ 2109. When installing the device, it is necessary to install a new bracket and find a place for the ignition module. The work procedure includes: Dismantling the VP for spark plugs. Disconnecting the wire connectors from the ignition module of the car. Disconnecting the clutch housing of this module from the cylinder block. The remaining three nuts securing the module are unscrewed, which is then removed. The ignition module takes a different place and new fasteners are installed. A bracket for mounting the fourth support is attached to the cross member of the front suspension. A bolt is installed in the hole on the terminal clamp, the nut is placed and screwed initially by two turns. The lower head of the rod is inserted into the support fixing eye. The bolt is installed in the eye and support, the nut is tightened. The size of the rod is adjusted until the holes in the clutch housing and on the upper head coincide. Another bolt is installed.
