How to change engine mounts for VAZ 21124 16 valves

Replacing engine mounts on a 16-valve VAZ-2112 with your own hands: remove from the support

An engine mount is a special support that is designed to secure the engine to the car body. It is a structure made of a steel body and a rubber (rubber - approx.) cushion placed in it. Its main purpose is to minimize vibration on the car body coming from the engine.

The video shows the detailed process of replacing engine mounts on a VAZ 2110-2112.

Replacing the wing cushion with your own hands

Begin:

we place the car on the overpass;
we go into the salon;
remove the cover and the plastic handle on top;
Use special pliers (platypus) to remove the retaining ring;
we climb under the car;
The rocker pad is held in place by four nuts that need to be unscrewed.

Note. It is worth noting that the standard ring can be removed very easily, because it has special lugs. If you bought a new imported set of backstage cushions, then there is another locking ring without ears, but it is better not to install it, but to use the old one.

After replacement, defects in the backstage support are not detected in most cases. Assembly is carried out strictly in the reverse order: a support is installed, which is secured with nuts. It is necessary to consolidate the above listed theoretical aspects of replacing the backstage cushion with the help of photo and video materials. Instructions on how to do the replacement yourself will be most effective if you have some visual reinforcement. In most cases, the price of the issue is small, but everything depends directly on the quality of the part itself. You can also find out about replacing the short-stroke rocker on our website.

Step-by-step replacement process

Depending on which support has failed, we replace it.

Right pillow

In order to unscrew the engine mount on the right side, we perform the following procedure:

Remove the top nut on the cushion.
Then two bolts that secure it to the bracket.
Next, under the wheel arch, remove the bolts securing them to the side member.
Remove the old element and install the new one in the reverse order of removal.

New right engine mount

Left pillow

As in the case with the right pillow, remove the upper nut.
Then unscrew the two bolts on the sides and remove the pillow.
Remove the bottom washer from the stud.
Install the new pillow in the reverse order.

Lower front airbag

Using a wrench, unscrew the two bolts one by one.
The sequence doesn't matter. Carry out dismantling depending on your convenience.
We dismantle the old pillow and install a new one.
If the inspection holes do not line up during installation, the engine must be raised slightly. You can use a jack for this.

Upper front airbag

This is what the new upper engine mount looks like

Using the key set to “17”, unscrew the bolt securing the support to the body.

If the bolt does not come off, you can use WD-40.

We replace the old pillow with a new one.

Installing a new pillow

Please note that during this work, it is strictly forbidden to dismantle all the cushions at once, since in this case, the engine will simply have nothing to support it. Replacement should be done strictly one by one, starting with one of the four supports. Also, for the most reliable fixation, you can put wooden supports or a jack under the engine.

Malfunctions

You can tell that the engine mounts are out of order by the increase in vibrations emanating from the engine to the body. When it operates in a stable mode, and the body begins to vibrate and rattle, transmitting everything to the pedals, instrument panel and steering wheel, you can be sure that the engine mounts are faulty.

Also, wear of the pillows is often observed when starting the engine and turning it off. So, if there is a lot of wear, a noise may be heard about the contact of engine elements and the metal supports of the cushion.

Functionality check

Before you start replacing pillows, you should make sure the old ones are working. Because it may not be necessary to change them all at once.

First of all, with the engine running, inspect the condition of the airbags:

For the presence of cracks.
To maintain elasticity.
Check for play in connections.

If such reasons are not observed on a certain pillow, then it does not require replacement. And if they are found, then there is no point in delaying replacement, since constant vibration can not only significantly reduce the comfort of driving a car, but also lead to negative consequences in the operation of the engine and gearbox.

Checking the condition of the pillows

We do it in the following sequence:

We lift the car and put it on supports;
We place a jack under the crankcase pan, place a board (wooden block) between the head of the jack and the crankcase - so as not to damage the pan;
Raise the engine with a jack until the weight of the engine stops putting pressure on the cushions;
We inspect the pillows for cracks. The pads should be hard and easy to separate from the metal backing ;
We check for play between the pillow plates and the motor frame. If there is play, you need to lower the engine and tighten the nuts and bolts securing the airbags;
If the cushions are intact, lubricate them with a protective compound before lowering the engine.

Reasons for failure

Among all the reasons for the failure of engine mounts, the most basic can be identified:

Spent life of engine mounts due to mechanical impact.
Wear of rubber elements due to constant changes in ambient temperatures.

Before you go to the store, you should determine whether it is worth changing only the cushions or the entire support assembly. Depending on the condition of the metal supports and the absence of damage on it, you can replace only its rubberized component.

The price of a set of pillows for a 16-valve VAZ-2112 is about 1,500 rubles, and the assembled supports are 3,000 rubles.
Work on replacing pillows in car services varies within 500 rubles per piece, however, we believe that this is a waste of money, and we suggest that you carry out this work yourself, since no special skills are required for this.

Replacing engine mounts on VAZ-2110, 2111, 2112

A cushion is an element of an engine support that serves to secure the engine to the car body.
The support is a rubber-metal structure consisting of a steel body and a thick rubber pad. The main role of the pillow is to dampen vibration coming from the motor.

On VAZ 2110 cars, eight-valve engines are attached to the body by 3 supports (two side and rear), and sixteen-valve engines are attached to 4 (two side, lower front and upper front).

Engine Mount Replacement Guide

If during operation of the car you experience body vibration at idle, then, first of all, you need to check the engine mounts. It is quite possible that they served their time.

In this article we will look at how to change the left and right mounts (mounts) of a VAZ 2110-2112 engine. To complete the work we will need the following:

Inspection pit or overpass;
Jack;
Socket wrench 15;
Socket wrench 13;
A little strength and patience)).

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.

Do I need to change

There are no recommendations for replacing pillows depending on their service life, but once you determine that they are faulty, you should not delay replacing them. Vibration processes can not only worsen the comfort of the driver and passengers, but also lead to destructive processes in the engine or gearbox itself.

Having decided to repair the engine mounting elements, you need to decide whether you will change the cushions themselves or the mounts assemblies. In principle, if the metal support itself is not damaged, it can be left, replacing only the pillow.

The price of a set of pillows for a VAZ 2110 costs around 1,300 rubles. The cost of a complete set of supports is about 2,500 rubles.

For the work of replacing engine mounts or mounts at a service station, you will be charged at least 300 rubles for each.

For eight-valve engines

Prepare the car for repair: place it on a flat surface, place stops under the rear wheels, remove the engine protection.
Unscrew the generator belt tensioner bolt and remove the belt (key 13).
Place the jack under the engine, place a thick wooden beam or board under its upper part. Raise the engine to remove the load on its mounts.
Unscrew the nut of the central fastening of the right pillow (15 wrench).
Unscrew the bolts securing the pillow to the bracket (key 13).
From the bottom side of the right arch, unscrew the 3 bolts securing the bracket to the spar (17 key).
Remove the bracket and replace the old cushion with a new one.
Carry out installation in reverse order.
Move the jack under the gearbox and lift it up.
Unscrew the nut of the central fastening of the left pillow (15 wrench).
Unscrew the two bolts securing the support and remove it (key 13).
Replace it and reassemble the structure in reverse order.
Unscrew the two 17 nuts securing the cushion to the body, and then two more nuts securing it to the gearbox (removal and replacement of the rear support is carried out from the bottom of the car).
Remove the rear support.
Unscrew the nut securing the pillow to the bracket (19mm wrench). Remove the old pillow and install a new one.
Install the rear support in reverse order.

For sixteen-valve engines

Removing and replacing side airbags is done in the same way as for 8-valve engines.

Work to replace the front lower airbag is carried out from underneath the machine.

Unscrew the bolt securing the front lower support rod to the front suspension cross member (15 wrench).
Unscrew the nut of the bolt fixing the support to the engine bracket (2 wrenches x 15). Remove the bolt.
Remove the support, replace the pillow or the entire structure.
Carry out installation in reverse order.
In the engine compartment, unscrew the bolt securing the upper front support to the body, holding its nut with your hand (17 wrench).
Remove the bolt and nut.
Unscrew the bolt securing the front upper support to the engine bracket (15mm wrench). Remove the bolt and nut.
Remove the support, replace the pillow or the entire structure.
Install it in reverse order.

What is needed for repairs

First, you need to determine which support on the VAZ 2110 engine should be changed (if you do not want to change all the damper mounts at once). To do this, you need to do an independent inspection of these parts. Sometimes, the power plant seems to be tilted horizontally on one side or tilted along the central axis of the car. This is the first sign to replace the damper mounts.

A couple of short boards

Two cushions (side) secure the engine to the left and right side members in the engine compartment. And one (rear) fixes the motor to the bottom. Therefore, it is necessary to lift the machine on a lift or install it on a viewing hole. The wear is immediately visible. The rubber has tears and core failure. Depending on the result of visual diagnostics, you should purchase the required number of parts for installation.

You will need a tool. In most cases, a standard locksmith set consisting of open-end and box-end wrenches with heads will be sufficient. In addition, to replace engine mounts on a VAZ 2110 you will need a rolling jack and a pair of short boards. It is advisable to have electricity and a cutting machine with a disc, since you may have to cut off the mounting bolts.

Helpful information! A couple of hours before repairs, it is strongly recommended to apply universal lubricant “Liquid Key” to the threaded connections. Damper supports are changed very rarely, therefore, unscrewing them without prior preparation is quite difficult.

Design and purpose of tens engine mounts

Over the years, vast practical experience has been accumulated on the topic of how to change engine mounts on a VAZ 2110, and videos of repair processes can also be found in abundance. However, few people pay attention to the features of the part. And, it must be said, it is in vain, because such knowledge will help to accurately determine the source of vibration and purchase the necessary spare part for repair.

The main purpose of the engine support is to reduce the level of vibration transmitted from the power unit to the car body. The rubber-metal structure consists of a steel base with a thick rubber cushion. The device has proven itself well, since it is quite reliable and is worth the money.

The eight-valve Lada 2110 engines are attached to the body at three points: right, left and rear. The side supports connect the body to the engine block through through holes. The rear support is attached with two bolts to the gearbox, and two nuts to the body. The importance of this damper part is very significant - it prevents longitudinal vibrations of the internal combustion engine during braking and acceleration.

Alternative supports

Considering the long-standing problem of Samara and a dozen, the manufacturer immediately released a whole series of alternative pillows:

OJSC-BRT;
SS-20;
"Assomi".

Let's now consider their features:

The support of JSC-BRT and the peculiarity of its structure is contained in a hinged product, which replaced the bearing in this place. At first glance, it looks like a panacea, since the general principle of operation seems to be clear: the creators of this technical innovation used an element that has increased rigidity in the radial direction. At first glance, the sounds should disappear and the car should become silent on uneven roads, however, conflicting reviews from the motorists themselves do not allow us to completely agree with this fact.
An alternative to OAO-BRT is SS-20, where a steel bushing was installed in place of the standard bearing, which was completely welded into a rubber damper. The manufacturer of this new product claims that the SS-20 will completely eliminate the appearance of elevators and extraneous sounds. Moreover, the manufacturer directly promises that the SS-20 will be able to guarantee the classic behavior of the rocker (see Replacing the rocker on a VAZ 2110 on your own): regardless of the topography of the road surface, the lever will be stable and without extraneous sounds.
The developers of "Assomi" boldly claim that the use of a special prescription rubber mixture will completely smooth out all impacts and sound noise, thereby significantly increasing the overall level of comfort of the car.

So, you need to choose who to trust, because there are a huge number of manufacturers to choose from, who all guarantee the high quality of their products. And most importantly, they guarantee that they managed to create a universal high-tech product that is most effective from a practical point of view.

Note. But it’s not entirely clear why some manufacturers of backstage cushions use rubber ears that quickly break?

Practical Feature of Alternative Choice

Unfortunately, “Assomi” and SS-20 are quite difficult to find in local stores; in the future they will go on wide sale, however, it is impossible to answer exactly when this will happen. It all depends on the store owners. The motorist is mainly offered imported products, as well as from national manufacturers, but only standard ones. It should be objectively understood that the quality of imported products varies significantly in comparison with national standard factory models, as does the price. Therefore, if you are pressed for time, it is best to order your own national alternative via the Internet, which is much lower in price than its foreign counterpart, and the quality is almost identical.

When to change your pillow

Factors that indicate the need to replace the wing cushions:

extraneous sound during movement, the irradiation of which can even spread to the body of the vases;
traces of hardening or cracking of the rubber cushion are visible, as well as if it is separated from its metal base;
there is a pronounced increasing vibration that has not previously been observed;
in case of unsatisfactory backlash length, etc.

When should you change the power unit mounts on a VAZ 2110: signs and reasons

Before you change the engine mounts of a VAZ 2110 car and watch a video of this process, you need to study the signs that indicate a breakdown of the rubber-metal mounts. The main symptoms characterizing problems with damper units:

Vibrations transmitted to the steering wheel and pedal unit when idling.
Extraneous noise in the cabin when moving on an uneven surface.
A characteristic knocking sound in the engine compartment during acceleration and braking.

When drawing conclusions after your observations, you should not confuse vibrations on the steering wheel during braking, which are associated with defects in the brake discs or pads. To be more convincing, you need to open the hood and inspect the power unit supports. If you place your palm on a running internal combustion engine, you can feel changes in its operation.

Many years of experience in operating the Lada 2110 allows us to assert that the reasons for the failure of damper cushions are the following factors:

Deformation phenomena on the rubber support due to mechanical and temperature influences, as well as due to exhausted service life.
Cracking and delamination of rubber from exposure to chemically active components.
Loss of elasticity caused by temperature changes.

Premature failure of the damper support can be caused by the owner’s excessive enthusiasm for such extreme techniques as sudden starts and emergency braking. Suspension parts are already subject to serious stress while driving, and a sporty driving style further increases the risk of their failure.

We repair competently: how to change the damper mounts of a VAZ 2110 engine and video of work processes

Replacing bearings is, of course, more troublesome than adjusting the clutch . but if you have the skills and a minimum set of tools, it is quite feasible without the help of car service specialists. To work, you will need a jack and a set of wrenches; you also need to take WD-40 fluid in advance - it is possible that the connecting elements are covered with rust. To perform a cycle of work, you need an inspection hole or a lift.

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.

Replacing the left damper support

The procedure for changing the engine damper on the left side of the car is performed in the following order:

Remove the car crankcase protection.
Place a jack under the car in the area of the gearbox, place a wooden beam and lift the car, removing the load from the support.
Using a 15mm socket and a wrench, unscrew the support pin fasteners.

Release the support stop.
Lower the jack slightly to freely remove the support pin.
Using a 13mm socket, remove the fasteners of the engine support to the body.
Pull the support towards the motor.
Remove the lower support stop and install the new part in the reverse order.

Replacing the rear damper mount

Reading how to change the rear engine mounts on a VAZ 2110 and watching the video is half the battle. It is important to strictly adhere to the order of repair work:

Remove the engine crankcase protection.
Using a 17mm socket, unscrew the two nuts securing the support to the car body.
Using two 19mm wrenches, unscrew the two bolts securing the gearbox and remove the support.
Clamp the removed bracket in a vice and use a 19mm wrench to unscrew the bolt securing the support.
Remove the bolt and install a new rubber support in the bracket.
Assembly of the unit is performed in the reverse order while maintaining the perpendicularity of the mating planes.

Based on practical experience, it can be argued that the process of replacing the damper supports of the power unit on the “ten” is not particularly difficult. Usually, after repair, vibrations disappear, but if everything remains unchanged, then the solution to the problem may lie in a different plane. It makes sense then to look for a problem in the suspension or in the CV joint components.

How to check engine mounts yourself? Simple tips

First, you should drive the car into a garage or other area with a flat floor;
Secondly, we lift the car using a jack at the same time from the front wheels and in the middle of the car, more precisely under the engine, we install a wooden log or other support and remove the jack;
Third, lie under the car and inspect the engine mounts. A visual inspection can reveal: hardening of the rubber, the presence of cracks and tears, as well as delamination of the support, or more precisely, separation of its metal part from the rubber.

1. Disconnect the wire from the battery that goes to ground, lift the car and install supports if necessary;
2. Using a jack, lift the engine to provide access to the faulty part;
3. Unscrew the bolts from the mounting points to the engine and body and remove the faulty part;
4. Install the new one in place of the old one and tighten it, while in order to avoid vibration and extraneous noise, tighten the nuts with the engine running. And assemble all the components that were previously dismantled.
