How to check the engine mountings of a VAZ 2112 16 valves

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).

DIY VAZ 2112 repair

Domestic cars are attractive due to their affordable price and ease of maintenance.
Repairing a VAZ 2112 with your own hands allows you to learn more about the car. VAZ models often have congenital defects and have great potential for tuning. And that's why I'm a frequent visitor to the service station. Photo of the VAZ 2112 car.

VAZ-2112 (LADA 2112) is a Russian car produced by the Volga Automobile Plant. The model was mass-produced for 10 years - from 1998 to 2008. The Lada Priora replaced the Zhiguli (the popular name for the 2112 model).

VAZ 2112 is built on the VAZ 2110 platform. The new model was produced in a hatchback body. Structurally, the two models are identical, only the VAZ 2112 has a reduced body length. The rear seat is borrowed from the VAZ 2111.

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:

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

Installing a new pillow

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.

Functionality check

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.

In today's article we will talk about such important elements of the transmission as gearbox mounts. Many car enthusiasts do not even know what they look like or where they are until these products make themselves felt with various types of malfunctions.

In order to understand and promptly respond to emerging problems with gearbox mounts and resolve the issue with minimal means, we will try to talk about their purpose and malfunctions in more detail.

Gearbox support for VAZ 2114: new on the left, old on the right

Purpose

The gearbox supports are designed to secure it to body elements, as well as to suppress vibration and noise when driving.

Manual transmission cushion VAZ 2112

Device and types

Depending on the design of the vehicle, gearbox supports can be made in different designs. Depending on the type of cushion, the boxes can be rubber-metal or hydraulic.

Rubber-metal

This type of product is a simple design consisting of two metal plates between which there is wear-resistant rubber.

Rubber-metal box cushion for VAZ 2110

This is the cheapest and most popular type of pillow. Recently, some manufacturers have begun to replace rubber with polyurethane due to its increased wear resistance. This type of support is available in both collapsible and non-dismountable versions.

Hydraulic

These cushions are a more modern design and are able to effectively smooth out any vibrations, adjusting to the operation of the power plant.

The support itself is a housing with two chambers located in it, with a membrane between them. Both chambers contain a hydraulic filler. The purpose of the membrane is to eliminate slight vibration when the car is not moving quickly on a flat highway and the engine is idling.

Hydraulic support

The liquid in the chambers is responsible for the vibrations that appear at speed. The changing pressure forces it to move between the chambers of the support, increasing the stiffness of the cushion, while dampening almost any strong vibrations.

Basic faults

On average, the service life of gearbox supports is about 100 thousand kilometers or more. However, during long-term operation of the vehicle, the power unit supports experience various loads, plus temperature changes, which negatively affects their condition. The rubber of the cushions loses its elasticity, delaminates, or cracks, and eventually completely collapses.

Large loads on the gearbox supports occur when starting and braking the vehicle. At the same time, if the driver prefers an aggressive driving style, that is, he starts abruptly and brakes sharply, then the airbags simply will not be able to last their service life and will fail ahead of time.

Malfunctions also include collisions with various obstacles, when the support bracket itself may be damaged. In addition to this, oil or antifreeze leakage that gets onto the rubber base of the cushion can also reduce the service life of the support. Plus, there is a high thermal load in the engine compartment with simultaneous splashes of cold water.

Signs of a faulty support

A failed gearbox cushion will make itself felt with characteristic signs. So, when driving or braking the car, unpleasant clicks, jolts, knocks, squeaks and noise will appear in the area of ​​​​the front of the car.

When driving over various uneven surfaces, shocks will again appear in the front of the car, as well as vibration and feedback to the gear shift lever. Plus, when the support wears out, a characteristic squeaking and clanging sound often appears and can interfere with speed.

On rear-wheel drive car models, if the gearbox mounts are worn out, shifting gears will be difficult, plus the car will vibrate while in motion.

A support malfunction can also be determined by structure-borne noise, for example, when starting and stopping the engine, as well as when the load changes.

Checking status

The condition of the supports can be checked visually. Upon inspection, the product should not show cracks (most often appear along the edges), tears, delaminations, or hardening of the rubber. Sometimes, when hardening, the rubber part peels off from the body of the pillow, which will be visible upon inspection.

Transmission cushion requiring replacement

When the silent blocks of the gearbox supports wear out, the gearbox linkage fastenings may break, the cushions may become deformed with the appearance of cracks, and eventually the support may burst.

For the presence of backlashes

The malfunction of the gearbox cushion can be determined in the inspection hole or overpass during its inspection. You need to apply force to the box, moving it sideways or up and down, while looking at the condition of the support. You can also apply force to the support using a pry bar. A worn part will “move” with its internal part. The working support in this case will look like a single whole, elastically resisting the applied load.

In addition to the supports themselves, their mounting bolts may fail, which will be visible from the sagging box.

General replacement scheme

Dismantling and installing a new gearbox cushion on most car models can be done with your own hands, without turning to car service professionals. It is enough to have an inspection hole in the garage, not be afraid of dirty work and purchase a minimum list of tools.

To work you must have:

• Jack;

• the necessary set of tools (the list is indicated in the repair manual for this vehicle);

• Safety stands for the engine;

• New product.

Operating procedure

• The car is placed on the inspection hole, the handbrake is raised and supports are installed under the wheels;

• The battery and battery stand are removed (depending on the design of the car model);

• The body is lifted with a jack, and a reliable piece of board is placed under the power unit across the inspection hole. If the garage has a manual hoist, then only the engine itself is raised;

• Stops are placed on the board and the body is lowered onto them from a jack, thereby unloading the supports;

The photo shows the replacement of gearbox cushions using the example of an Audi 80

• The gearbox support fasteners are released and removed;

Unscrew the bolts and dismantle the support

• Before installing a new cushion, you need to place it on the future location and check the alignment of the holes in the support and the holes in the body. If necessary, you can lower or raise the body a little with a jack;

• A new product is installed, the fasteners are made using the torque prescribed by the manufacturer, and everything is assembled in the reverse order.

Finally

To extend the service life of the supports, we recommend choosing a gentle driving mode, avoiding sudden acceleration and braking. Also, periodically pay attention to the condition of the power unit cushions in order to replace them in a timely manner. It is recommended to check them at every scheduled maintenance or when signs of malfunction appear.

If oil or coolant gets on the supports, clean and wipe them dry, keeping the rubber from corroding.

How the engine is mounted in a VAZ2110 car

The engine of a VAZ 2110 car is mounted in the car in the engine compartment. The supports are three elastic elements. The right support is attached to the engine bracket, and the left and rear supports are attached to the gearbox housing brackets. The last two supports are similar in design.

How to replace the right engine mount of a VAZ 2110 car

So:

• The top nut securing the engine mount is unscrewed.
• The two bolts holding the element to the bracket are unscrewed.
• The bolts that connect the bracket to the side member are unscrewed under the wheel arch.
• The bracket for the right engine mount of a VAZ 21103 is pulled out of the car.
• The old cushion is replaced and a new one is installed in the reverse order of disassembly.

How to replace the left engine mount of a VAZ 2110 car:

As in the first case, the upper nut fixing the pillow is unscrewed. But the engine on this side needs to be lowered.

•

• The engine is lowered onto the prepared support.
• The upper washer of the pillow is pulled out.
• The bolts securing the element are unscrewed.
• The left cushion under the VAZ 2110 engine is removed.
• The lower washer is removed along with the pin.
• The left engine mount of the VAZ 21102 is replaced with a new one, and assembly is performed in the reverse order.
• Using a socket, the nut that secures the rear cushion to the body is unscrewed.
• The mount of the engine mount on the VAZ 2110 to the gearbox is unscrewed.
• The pillow is removable.

How to replace the rear airbag of a VAZ 2110 car

Removing the rear cushion of a VAZ 2110

The rear airbags can be equipped with or without a bracket. The part is a one-piece cast element, which has all the necessary holes for mounting the pillow. To increase reliability and rigidity, ribs are located on the inside of the bracket. The upper motor mount bracket is an intermediate link between the engine support pad and the flexible rod. With its help, you can change the angle of fixation to the body and strengthen the fastener design.

So:

• Installation of the new part is carried out in the reverse order.
• The assembly of the unit is performed in reverse of its disassembly.

To correctly replace VAZ 2110 engine mounts, you can watch the video.

Tuning engine mounts for VAZ 2110

A fairly affordable tuning element with which you can make the engine mount more rigid is to replace the factory standard mount with an element with a more rigid body and a rubber support part. This device allows you to:

• Reduce engine movement as much as possible when braking, abruptly starting the car, or hitting bumps.
• Increase the service life of the exhaust system and drive wheel drives.
• Protect against self-switching gears.
• A bright tuning part will be installed under the hood.

Tuning part for VAZ 2110 engine mount

To increase engine rigidity, you can install a fourth support for the car’s power unit. It connects the cross member of the front suspension of the VAZ 2110 car and the clutch housing. Such a device can be installed both for mounting an 8-valve and 16-valve engine. When installing an additional support, you need to find another place for the ignition module and purchase a new bracket. The general view of the device is shown in the photo.

Installation instructions include:

• 
  How to fix the engine of a VAZ 2110 8 valves

• Removal of spark plug armored wires.
• The wire connectors from the car's ignition module are disconnected.
• The fastening to the cylinder block and clutch housing of the ignition module is turned out.
• The last three nuts securing the module are unscrewed, which is then removed.
• A new fastener is screwed in and the ignition module is installed in a different place.
• The fourth support bracket is screwed onto the front suspension cross member.
• A bolt is inserted into the hole in the terminal clamp, a nut is installed and tightened two turns.
• The lower head of the rod is placed in the support fixation eye.
• A bolt of the appropriate size is inserted into the hole of the eye and the cushion, and the nut is tightened.
• The size of the rod is adjusted until the hole in the clutch housing matches the hole on the upper head.
• Another bolt is inserted.

Installation of the fourth engine mount VAZ 2110

• The clutch housing shield and the rod head are attached through a spacer sleeve on the support.
• All bolts are tightened.
• When installing another mount for the ignition module, bolts are screwed into the threaded hole on the cylinder block.
• The bottom and top of the bracket are attached, all bolts are tightened.

When installing the fourth support, the price of the engine mounts will increase, but the reliability of mounting the engine of the VAZ 2110 will also increase.

Do-it-yourself replacement of a VAZ 2110 engine mount

So, having decided that replacing the engine mounts is inevitable (either one or several, for example, replacing the rear engine mount), you need to prepare the car and tools for repair work (drive the car into a pit or onto a lift, have a set of keys, jacks, etc.).

In the case of an 8 valve engine:

• First, use a 13mm wrench to unscrew the alternator belt tensioner bolt and remove the belt;
• A jack is placed under the engine, a wooden beam or a thick board is placed on the top of the jack;
• Next, the engine is raised with a jack so as to relieve the support;
• Then, using a 15mm wrench, unscrew the central nut securing the right airbag;
• Then, using a 13mm wrench, unscrew the bolts securing the pillow to the bracket
• Next, from below in the area of ​​the right arch, using a 17 key, you need to unscrew 3 bolts (the bracket is attached to the spar);
• Now the bracket can be removed and the engine mount can be replaced by tightening all the bolts back after installation.
• Upon completion, the jack at the bottom moves under the box, which raises the gearbox;
• Now, using a 15 wrench, unscrew the central nut securing the pillow on the left;
• Afterwards, you can unscrew the 2 bolts securing the support with a 13 key, and the support itself is removed;
• Next, a new support is installed and reassembled;
• Having completed the stage, you need to go down under the car, then unscrew a couple of 17 nuts (attach the pillow to the body);
• After this, unscrew two more nuts securing the element to the gearbox and remove the rear support;
• All that remains is to use a 19mm wrench to unscrew the nut that secures the cushion to the bracket, then remove the old cushion and install the new element;
• Reassembly completes the process; at this point, the replacement of the VAZ 2110 engine mounts can be considered completed;

Let us also add that for VAZ engines with 16 valves, both the process of removing and replacing the side airbags itself is no different from the process discussed above. When it comes to replacing the front lower airbag, you need to work from below.

First, use a 15mm wrench to unscrew the bolt that secures the front lower support rod to the cross member of the car's front suspension. Afterwards, the nut of the bolt that attaches the support to the engine bracket is unscrewed, and the bolt itself is removed.

To unscrew the bolt, you will need two 15mm wrenches. Now the support can be removed and only the pad or the weight of the entire element can be changed. Now we can proceed to reverse assembly.

The overall process of replacing the pillows is completed by unscrewing the fastening bolt of the upper front support to the body with a 17mm wrench. The bolt nut can be held by hand.

Then the bolt and nut are removed, after which, using a 15mm wrench, the bolt securing the front upper support to the power unit bracket is unscrewed (the bolt and nut are also removed). Next, the support is removed, the cushion or the entire assembly is changed, and reassembly is performed.

As you can see, the VAZ 2110 16-valve engine mount changes almost exactly the same as on an 8-valve internal combustion engine. The only difference is that there are more supports themselves, and the rear support is changed from below (in the bottom area). At the same time, with the right approach, there are still no special difficulties; it is quite possible to change the cushions on this type of internal combustion engine with your own hands in the conditions of an ordinary garage.

Having installed new VAZ engine mounts (engine mounts for 2110, 2112 and other similar models), you should start the engine to check. If the pillows or supports are of high quality, and the replacement itself is carried out correctly, normally there will be practically no vibrations.

Installing an additional gearbox cushion

• Rear cushion of the VAZ 2110 gearbox (8 cells), catalog number 2110-1001286/50;
• 2x Bolt M12*80 or M12*75;
• 2x Nut M12 with plastic;
• 4x Washer baud bolt M12;
• 2x Bolt M10*35 or M10*25;
• 2x Grover for M10;
• 4x Silent block washer;
• 2 keys “19”;
• key "17".

1. We fasten the additional support to the gearbox with two M12 bolts, using two “19” keys;
2. We fasten the pillow to the body with M10 bolts using a “17” wrench;
3. Make sure that the support is not stressed and there is a gap in the indicated place (if necessary, place washers under the bolts).

How to replace engine mounts on a VAZ 2110-VAZ 2112?

Note! In this article we will talk exclusively about 8-valve cars, if you are looking for information about 16-valve engines, then go to another article called: “Replacing the pillows on the engine of a Lada Priora car,” in fact, the pillows in these two engines are not particularly different , it’s just that in 16-valve cars, additional cushions were added and one rear engine cushion was removed, despite this, the left and right engine cushions are present in both 16-valve cars and 8-valve cars, but information on replacing these two cushions is only posted in this article, so if you start with them, then do not follow the links, but simply continue reading this article on replacement!

Replacing the left engine mount:

First, crawl under the car and place a support under the gearbox itself that will rest on the jack (This board can be and in no case do not lift the box with a jack alone, it may be damaged or if your jack has a flat surface and you are sure that it will not damage the gearbox body, you can try to lift the gearbox without any support), then lift the jack a little at a time (it’s best to use a hydraulic one, it’s unlikely to fall off, but you just need to secure it well) and behind the gearbox, a little the engine itself will rise, when this is done, unscrew the nut securing the engine to the cushion (Indicated by the red arrow) and carefully lower the jack so that the rod comes out of the cushion, as soon as the operation is completed, unscrew the two bolts that secure the cushion (Indicated by blue arrows) and completely remove it from the car, install a new and metal support on it, which you also removed from the old cushion, then lift the engine again by the box and tighten the nut that secures the engine rod to the cushion, but only before that, be sure to tighten the bolts securing the cushion to the body.

Replacing the right engine mount:

The replacement is carried out as with the left cushion, namely, a jack is placed (Indicated by a red arrow), but not under the gearbox, but under the engine crankcase (Indicated by a blue arrow) and after which it lifts the engine and the nut that secures the power unit to the cushion is unscrewed (see small photo, it just shows unscrewing this nut), then the two bolts securing the airbag itself are unscrewed (indicated by green arrows) and it can already be removed from the car.

Note! This cushion is placed on the bracket, if suddenly it is bent or if you just want to change it, then unscrew the three bolts securing this bracket to the body spar and then remove it, by the way, before starting this operation, remove the generator belt, as To do this, read the article: “Replacing the alternator belt on a car”, point 1 you need!

Replacing the rear engine mount:

This cushion is the easiest to get to and, as a rule, if you have a good tool, it can be quickly removed, and this is how it is removed: first, a jack is placed under the gearbox and it lifts it a little, then two nuts are unscrewed (They are not visible in the photo below, the pillow itself is indicated by a blue arrow and the knob is indicated by a red one, with the help of which one of the nuts is unscrewed) which secure the pillow to the body and two more nuts of bolts that secure the pillow through the bracket to the box (These nuts are indicated by green arrows in the small photo) and you can remove an old pillow, together with a bracket from the power unit.

Note! Pillows in the store can be sold either assembled with a bracket or without it, if you suddenly bought just such a pillow, then be sure to remove the bracket for it from the old one, they are fastened together with just one bolt (Indicated by the red arrow), by unscrewing it, the bracket can be separated from the pillow (We recommend clamping the bracket in a vice, this will make it much more convenient to unscrew the bolt)!

Replacing the gearshift pad on VAZ-2110, VAZ-2111, VAZ-2112 cars

On VAZ-2110, VAZ-2111, VAZ-2112 cars, when unpleasant rattling, vibration and increased play in the gearshift knob appear, the happy owners of these vehicles should pay attention to the condition of the ball joint race of the gear shift link or as it is also called in common parlance gear shift pad . There is another option - backstage butterfly . But, I personally like the second option))). Due to the fault of this very pillow (ball joint cage) being completely broken, the clarity of gear shifting may also disappear. Yes, I know that all the listed symptoms also include a broken cardan (joint) of the gear selection rod. What kind of cardan is this and how to replace it you can find out from this article. But we’re not talking about him now and let’s assume that everything is ok with him. Or, as another option, the cardan was replaced, but the rattling and play of the rocker did not disappear. This also happens; not everyone immediately pays attention to the backstage cushion. But, it exists and it periodically fails (breakage of rubber “ears”, ejection of metal bushings, breakage of a plastic bushing or spring). The destruction of the rubber part of the cushion (ball joint race) of the rocker is not difficult to replace (see photos 1 and 15). And if you find them, then it’s time for you to get ready for work. Let me reassure you right away, it’s not complicated. But for everything to go smoothly, you need to be thoroughly prepared. That is, buy the necessary spare parts, decide on the location of the work, assemble the necessary tools and, of course, familiarize yourself with and remember in what sequence you should replace the cushion (ball joint race) of the gear shift lever on VAZ-2110, VAZ-2111, VAZ- 2112 . And I will try to help you with this, and I invite you to further read this material.

Spare parts. Here the choice is obvious. I recommend choosing the ball joint clip for the gearshift mechanism of VAZ 2110-2112 cars - BRT (Balakovo) . As they say, time-tested quality. Photo 2.

List of tools that you will need to replace the cushion (ball joint race) of the gearshift slides of VAZ-2110, VAZ-2111, VAZ-2112 cars : a 13-socket and socket wrench, a 10-size combination wrench, pliers, a flat-head screwdriver and a small ratchet with with a cross attachment (photos 3 and 4). The need for a ratchet with an attachment will be shown a little later. And you should immediately decide on the location of the work. It is advisable to replace the cushion in an inspection pit, overpass or lift. Why is it desirable? Because this work can be done “from the ground”, but believe me, it will take more time and effort. And it will still be a pleasure.

And so, into battle! Let's proceed to independently replacing the cushion (ball joint cage) of the gearshift mechanism of VAZ-2110, VAZ-2111, VAZ-2112 :

1. Let's start working inside the car. Use a screwdriver to pry up the frame of the decorative cover of the gearshift slide (photo 5). Pull the lever handle up and remove it along with the cover.

2. Using a 10mm spanner, unscrew the two fastening nuts and the bolt of the reverse lock bracket lining and remove it (photos 6 and 7).

3. Using a 13mm wrench, unscrew the lever axle nut (photo 8). After this, use a wrench with an attachment (in my case it’s a ratchet) to unscrew the axle locking screw (photo 9). Without such a key, this screw will be difficult to unscrew. We take out the axle (photo 10). We remove the set of bushings from the lever, otherwise we risk losing them (photo 11). All. Now the work inside the car is finished, let's climb under the car.

4. Using a 13 mm socket wrench, unscrew the two nuts of the rocker pad bracket (photo 12). And remove the bracket.

5. Next, you should disconnect the reaction rod from the cushion (ball joint cage) of the rocker. We use a spanner wrench (hold the nut on top with it) and a 13mm socket wrench (photo 13).

6. Pull down the pillow along with the lever (photos 14 and 15). Remove the retaining ring (photo 16) and remove the lever along with the plastic bushing (photos 17 and 18).

7. That's it. We clean the lever hinge from dirt, lubricate it, and put on a plastic bushing. We place this whole thing in the pillow body and secure it with a locking ring (photos 19 and 20). We return this entire structure to its place (photo 21). Don't forget to put a cover on the pillow (photo 22).

Ready. We carry out the rest of the assembly in reverse order. The work on replacing the butterfly cushion (ball joint cage) of the gearshift gates of VAZ-2110, VAZ-2111, VAZ-2112 cars has been completed. I hope it’s successful))).

Design and purpose of tens engine mounts

Over the years, we have accumulated vast practical experience on the topic of how to change engine mounts on a VAZ 2110 and videos of repair processes can also be found in quantity

However, few people pay attention to the features of the part. And, I must say, in vain, because such knowledge will help to accurately determine the source of vibrations and purchase the necessary spare part for repairs

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.

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:

1. Vibrations transmitted to the steering wheel and pedal unit when idling.
2. Extraneous noise in the cabin when moving on an uneven surface.
3. 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.

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.

Detailed instructions for disassembling and repairing the VAZ 2110 engine:

2. Remove the clutch from the engine.

3. Remove the tension roller, camshaft drive belt and spacer washer, which is installed under the tension roller.

4. Remove the toothed pulley from the camshaft.

5. We unscrew four bolts, three of which attach the water pump. Unscrew the fastening nut on the rear cover of the camshaft drive belt and remove the cover.

6. To remove the water pump, insert a screwdriver between the block and the flange of the pump housing and thus move it from its seat. After completing these operations, remove the water pump.

7. Remove the head from the cylinder block.

8. Unscrew the bolts (there are 16 of them) securing the oil sump, then remove it together with the gasket.

9. Unscrew the bolts (there are 3 of them) securing the oil receiver and remove it. Please note that there are spring washers under the bolt heads.

11. Then rotate the crankshaft so that the piston that is being removed hits BDC (bottom dead center). It is necessary to unscrew the two fastening nuts to remove the connecting rod cover.

12. Now remove the connecting rod cover. In cases where it is difficult to dismantle the cover, you can first remove it with light blows of a hammer. It may be that the cylinder number on the cap will not be visible, in which case the cap should be marked with the cylinder number.

13

Using the handle of a hammer, push the connecting rod inside the cylinder, then carefully remove the piston and connecting rod from the cylinder. During the process, you need to make sure that the lower head of the connecting rod does not touch the cylinder mirror, since this can damage it

We remove the remaining pistons in the same way.

14. If you need to remove the piston from the connecting rod, then mark it with the cylinder number so as not to confuse them when installing them. There should also be a cylinder number on the connecting rod: if it is not visible, then we mark the connecting rod as well.

16. Unscrew the bolts (there are 6 of them), remove the crankshaft rear oil seal holder and the gasket. Remember that there are spring washers under the bolt heads.

17. Remove the toothed pulley from the crankshaft. If the key does not fit tightly in the groove of the shaft elbows, be sure to remove it so that it does not get lost.

18. Unscrew the six bolts, under the heads of which there are spring washers, and remove the oil pump and gasket.

19. We unscrew the mounting bolts on the five covers (each with 2 bolts) of the main bearings.

20. Remove the covers.

21. Remove the crankshaft of the VAZ 2110 car.

22. We remove the crankshaft thrust half-rings on the middle support.

23. If you do not plan to replace the liners, then as you remove them, remove them from the block beds and from the main bearing caps.

24. On the non-working side we mark the liners relative to the beds and covers.

25. If there is a need to remove the engine mounts and generator brackets, unscrew the bolts (3 pieces) securing them and remove the water pump supply pipe by unscrewing its fastening.

26. Remove the piston rings using a special puller. If there is no such device, then remove the rings from the piston by carefully releasing the ring locks.

27. Remove the oil scraper ring expansion spring from the auto engine piston.

28. Remove the retaining rings that hold the piston pin on both sides of the piston. There are recesses in the piston bosses for easy removal of the rings.

29. Using a suitable mandrel, push the pin out of the piston, then remove the piston from the connecting rod.

30. Remove the liners from the connecting rod and its cover. If they remain on the crankshaft, remove them from the shaft. If replacement of the liners is not required, then as they are removed, we mark them with respect to the numbers of the covers and connecting rods.

This completes the process of disassembling the VAZ 2110 engine. Good luck with the completion of the renovation.

Repair of VAZ 2110 (Lada): Repair of gear shift lever

2. Repair manual for VAZ 2110 (Lada) 1996+.
3. Gear shift lever repair

3.2.12. Gear shift lever repair

The gear shift lever should turn freely and without jamming in the ball joint.
Otherwise, check and replace the ball joint and spherical washer if necessary. If, after pushing down all the way, the lever does not return completely to its original position, check and, if necessary, replace the spring. Remove the upper and lower linings of the floor tunnel (see subsection 8.12 ).

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.

Signs and causes of malfunction of VAZ 2110 engine mounts

1. A strong hum in the cabin while the engine is running often indicates hard contact of the power unit with body elements. This phenomenon usually indicates the destruction of one of the supports on which the motor and gearbox connected together should rest. If their rubber cracks or even breaks away from the metal base, then the power unit receives an additional unwanted degree of freedom, creating noise.
2. A dull knock can also be heard when driving away sharply, due to the engine being misaligned on torn mounts.
3. In turn, the torn support is “given away” by a dull knock. every time you press the accelerator and every time you release the gas and switch to engine braking mode.

Sometimes the problem of extraneous sounds lies in the pressed, deformed crankcase protection. After going outdoors, dirt may accumulate in the gap between the adjacent protective sheet and the pan, which also leads to the appearance of an extraneous hum.

The appearance of so-called fatigue cracks in the engine support, which form over time, is also considered critical. They are usually identified by careful inspection of the pillows.

Are the instructions useful? Yes 2 No

Comfort inside a car depends on many factors, one of which is sound insulation. Body vibration is an important component, which depends on the suspension, the quality of the road surface, and also on engine operation. Engine mounts are designed to reduce vibrations on the body. Let's figure out how to replace engine mounts with your own hands.

Replacing the right engine mount for VAZ 2110, 2111, 2112

Removing the engine mount is shown using the example of a VAZ-2112 engine. For VAZ-2110, -2111 engines the process is similar. Remove the alternator belt, loosen the bolt securing the alternator to the engine (key 13). We loosen the bolt that secures the tensioner bolt and loosen the generator belt tensioner. We install a jack under the engine crankcase and jack it up.

1. Unscrew the nut securing the pillow (Wrench 15).
2. We unscrew the two bolts securing the pillow to the bracket (key 13).
3. We unscrew the three bolts securing the bracket to the right side member (head 17).
4. Remove the bracket (photo taken with the engine removed).

Having unscrewed the nut, as shown in photo 1, remove and replace the pillow.

Replacing the left engine mount for VAZ 2110, 2111, 2112

We install a jack under the gearbox and thereby raise the engine:

1. Unscrew the nut of the left support of the power unit (with a 15 wrench). Holding the gearbox, lower it to the stop.
2. Remove the upper cushion stop.
3. We unscrew the two bolts securing the pillow to the body (using a 13 key).
4. We remove the pillow.

We remove the lower stop of the cushion and take out the pin with flats that prevent it from turning in the gearbox bracket.

Replacement of rear engine mount VAZ 2110, 2111

Installing a jack under the gearbox:

1. We unscrew the two nuts securing the rear support to the body (head 17).
2. We unscrew the two bolts securing the support to the gearbox (with two 19mm wrenches) and remove the support.
3. To disconnect the rear support bracket and the cushion, unscrew the bolt (with a 19mm wrench) and hold the bracket in a vice.
4. We take out the bolt. We assemble the bracket and pillow in the reverse order, observing the perpendicularity of their mating surfaces and the correct location of the stops.

By the way, the absence of this gearbox support on a 16kL engine significantly increases the rattling of the gearbox lever.

Replacing the front lower engine mount of a VAZ 2112

1. Remove the engine splash guard. We unscrew the bolt securing the front support rod to the front suspension cross member (with a 15mm wrench).
2. We unscrew the nut of the bolt securing the rod to the front support bracket (with two 15mm wrenches), remove the bolt.
3. We remove the support. Installing the front support is not difficult if the remaining supports of the motor unit are secured in place. You only need to rock the engine slightly to align the holes.

This airbag is not installed on VAZ 2110 engines.

Replacing the front upper engine mount of a VAZ 2112

1. We unscrew the bolt securing the rear support rod to the body (Using a 17 wrench), holding the cage nut so that it does not fall out of the box.
2. We take out the nut and bolt.
3. Unscrew the nut of the bolt securing the rear support rod (with two 15mm wrenches), remove the bolt
4. We remove the barbell.

This airbag is not installed on VAZ 2110 engines.

Anyone who has at least once encountered minor car repairs can remove engine mounts on their own. The main thing is to follow the sequence of actions and, in some cases, jack up the gearbox.

By the way, in addition to the standard engine mounts, you can install additional support.

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

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.

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.

Lada Priora is a modernized version of the VAZ 2110; the design of these cars has many of the same parts, for example, doors or body parts. This allows you to adopt some improvements from the “ten”, one of which is the installation of an additional gearbox cushion.
