DIY VAZ 2109 engine mount repair

In detail: DIY repair of a VAZ 2109 engine mount from a real master for the site my.housecope.com.

Replacing the VAZ 2109 engine cushions is necessary when extraneous noise and vibrations appear. With their help, the volume of the engine is reduced, since the amount of vibration transmitted to the body is reduced several times. Repairing an old nine in the service is too expensive a pleasure. And the design of the machine is so simple that it allows you to carry out minor repairs and maintenance yourself, without resorting to the services of expensive craftsmen.

The strength of the pillows must be sufficient, since they are subjected to loads of various magnitudes and directions. The mass of the engine always acts on the body, whether the vehicle is moving or stationary. 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 should be experienced by the car body and pillows. Check regularly for defects. And if the engine mounts of the VAZ 2109 have pronounced damage (cracks, deformations), it is necessary to replace them.

Hitting a bump or a hole, a sharp acceleration of the car and braking, hitting an obstacle - all this causes the appearance of forces. Rubber mounts are used to damp them. The pillows are made of rubber, high quality steel, premium rubber type SKI-3, glue. Withstand temperature drops in the range of -45 .. + 70 ° C.

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

Any spare part has a warranty period. Further use of the element can be risky. When the rubber dries, its wear increases, the degree of vibration transmission becomes higher. The support can fail both for natural reasons and after minor accidents, falling into a hole or hatch, etc. Symptoms indicating that it is time to change the support:

Increased vibration of the car body, rattling of the panel and steering wheel.
Extraneous knocks arising at the time of acceleration and deceleration, difficult gear shifting. There is a feeling that the car's engine is moving on supports, and if you open the hood, you can even see how it does it.
Difficulties in replacing the timing belt, removing the crankshaft pulley. The engine, when sags, is as close to the right side of the car as possible. Impacts on the body are possible. The plastic cover cannot be removed; you have to move the engine block to the left with a pipe or a crowbar.
Decreased service life of grenades due to excessive sagging of the engine and changes in the geometry of the mechanism. Their work must take place in certain conditions, every angle matters. And the deviation from the normal leads to a rapid failure of the unit.
The box slider can hit the transverse rod housing, a knock appears from the side of the gearshift mechanism.

And the most important thing is that if you neglect the repair, then later its cost will only increase. We'll have to sort out the hodovka, the gearbox, and the engine elements. Therefore, replacing the engine mount is cheaper than major car repairs.

There is no need to install the car on a lift or a viewing hole, all work is carried out on a flat surface. But this is in the event that only the front cushion of the VAZ 2109 engine changes. In fact, it is only one, the other two are fixed on the gearbox. You will need the following parts and tools:

new front airbag VAZ 2109;

socket heads, ratchet and crank;

a set of spanner keys;

jack and supports;

penetrating grease type WD-40;

grease type Litol-24, SHRUS.

It is advisable to treat the threaded connections in advance with a penetrating lubricant. This will make the job much easier. The front airbag is located in the lower part of the engine compartment, there is often dirt and water, which negatively affects the metal. If a mudguard is installed, it must also be removed for the duration of the repair. Use socket heads to pry off all bolts. Place a jack under the engine floor and raise it. It is advisable to put a wooden block between the engine and the jack. Take care not to break the pipes and wires.Unscrew the nut located on the long bolt. It fixes the airbag with the bracket on the car body with a cross member. It is more convenient to work with two keys, with the second to keep the bolt from turning. To pull out the bolt, you need to slightly move the body, then the holes in the pillow and bracket will coincide as clearly as possible. Then remove the bolt that secures the support to the motor block. After removing the bolts, the pad can be removed. Mark the top of the pillow so that you can later install the new one in the same way. Otherwise, you will have to look for pictures in the literature or on websites.Installing a new front airbag takes less time. First of all, thoroughly clean the joints, lubricate the bolt threads with Litol or graphite. Install the pad and install all the bolts. Only then can the jack be lowered. All screw connections are now secured. Nuts with a plastic insert can be used to ensure a secure connection.

There are several factors that you should be aware of when it comes to replacing engine components.

Peculiarities

Feeling the vibration of the body, be sure to check the condition of the supports. This effect can be caused by various reasons, but pillows are one of the main

When replacing a belt, it can be very difficult to remove its cover, since the engine is almost closely pressed against the right mudguard of the front wheel. I have to take off the pillow in order to fully carry out repairs

The engine sags, loads the CV joints

Due to the effect of the engine mass on the CV joints, their geometry changes, which leads to a significant reduction in the operational life of the elements. The resource is reduced, you have to perform the replacement ahead of schedule

There is a knock in the backstage area

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

If you do not replace the supports in a timely manner, this will lead to more serious consequences and expensive elimination of the breakdown. Therefore, it is best to replace the pillows when primary signs of wear are found. For this, we additionally recommend carrying out a periodic inspection of the unit.

Now let's move on to replacing the elements. Do it yourself or contact a car service, purely your personal decision.

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

Front;
Back;
Left side.

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

Find a suitable place to carry out the repair. You will need a pit or overpass.

Place the car there, fix it with stops, put the car on the handbrake.

Disconnect the negative terminal from the vehicle battery.

Using a 17 spanner spanner, unscrew the nut that holds the pad on the body.

Using the 17 head, dismantle the mounting nuts of the support bracket to the gearbox. There are 3 of them in total.

Take out all the bolts, remove the old engine mount.

Install a new motor element and reassemble the assembly.

Provide yourself with free access to the bottom of your VAZ 2109.

Secure the vehicle with supports and a hand brake.

Disconnect the negative from the battery.

Remove the left engine mudguard.

Using a 17mm spanner wrench, remove the nut that holds the pad to the body.

Using a 17-inch head, unscrew the 3 mounting nuts of the support bracket, dismantling them from the gearbox.

After removing the mounting bolts, replace the worn out engine mount with a new one.

Carry out the reassembly procedure. Follow a strict sequence.

Here, observe all the same conditions that were relevant for previous work. That is, drive the car into a hole, put up supports and de-energize the car by removing the negative terminal from the battery.

Using a 17 spanner spanner, the nut that holds the pillow on the body is removed.
With a 17 wrench, remove already 4 fastening nuts securing the mount to the engine.
Remove the rubber element from the eyelet.
Replace the old assembly with a new support.
Reassemble the assembly.

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

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

Before replacing the POD, it is also the front engine mount on the VAZ 2109, I recommend reading about what the engine mountings are, what they are for, and also about the signs of malfunction of the pillows.

We put the jack and jack the engine a little.

Next, we process the bolts with WD-40 penetrating liquid, then unscrew them one by one.

We remove the old engine mount, and in its place we install a new one and fix it in the same way. Before tightening the bolts, I recommend treating them with graphite grease, this will simplify unscrewing in the future.

We tighten the bolts, after which the jack can be removed.

After front pillow VAZ 2109 replaced, the problems with vibration in the cabin coming from the motor should disappear. Check the result, if the vibration has not passed, continue troubleshooting, as an option, the reason may lie in detonation, faulty sensors or problems with spark plugs. I have everything, until we meet again at the VAZ Repair.

It's not a secret for anyone that any part of the car that is out of order (or just planning to do it) needs to be replaced in a timely manner. This applies primarily to engine pillows, because they themselves are inexpensive, but if you miss the moment, you will have to change not only them, but also more expensive elements, for example, the entire engine. You need it.

CV joints began to require frequent replacement.
It takes a lot of effort to remove the timing belt cover.
During the movement, vibrations of the body began to be felt.
When starting, braking, sharp acceleration, difficult gear shifting, a knock is heard in the car.
At least one of the pillows has “visual problems”: cracks, subsidence, etc.

Before telling you about how the engine cushions of the "nine" are replaced, you should make a reservation how many of them are in the car - there are 3 of them in the "nine" (front, rear and left / side), because the process of replacing each of them we will considered separately.

1. Find a convenient place for repair work, it should have a pit or overpass.

2. Drive the car there and fix its position with stops.

3. Disconnect the minus from the battery.

4. Using a 17 spanner spanner, unscrew the nut securing the pad to the body.

5. Using a 17-inch head, unscrew all the fastening nuts (3 pcs) of the support bracket to the gearbox.

6. Remove the bolts and replace the pad with a new one. Assembling the removed parts should be done in strict reverse order.

The work is carried out under the same conditions as before: you have free access to the underbody of the car, the car itself is carefully fixed and de-energized.

1. Remove the left engine mudguard.

2. Using a 17 spanner spanner, unscrew the nut securing the pad to the body.

3. Using a 17-inch head, unscrew all the fastening nuts (3 pcs) of the support bracket to the gearbox.

4. Remove the bolts and replace the pad with a new one. Assembling the removed parts should be done in strict reverse order.

The conditions for the repair work are the same: the car is parked on an overpass (in a garage with a viewing hole), wheel chocks are under the wheels.

1. Using a 17 spanner spanner, unscrew the nut securing the pad to the body.

2. With the same 17 wrench, remove the 4 nuts securing the mount to the engine.

3.Pull out the rubber support from the eyelet and install a new one in its place, performing all the above steps in reverse order.

Hello dear, blog readers. Today's article will be devoted to replacing the engine mountings of a VAZ 2109 front, side and gearbox. The factory engine mountings of the VAZ 2109 are quite reliable and serve for quite a long time. This is due to the fact that high-quality materials were used in their manufacture, and the technology of the structure of production of industrial rubber goods of industrial rubber goods was also observed.

Before starting work, it is necessary to process all the fasteners of the supports with an anti-rust solution, which will facilitate the replacement process itself. When lifting the engine, care must be taken not to damage the elements of the wiring or pipelines, performing this work slowly. The socket head "undermines" all the mounting bolts of the pillow and the engine rises, then it is most convenient to work with a ratchet wrench.

It is best to start the replacement with the long bolt connecting the bracket on the cross member to the support. After giving the nut, you need to try to pull out the bolt, "playing" for this back and forth, with a hoist or a jack. As soon as the common center is "caught", the bolt will come out with a light hand force.Having found this position, leave the bolt in the connection and give back the bolts for attaching the pillow to the engine block, after which, having removed all the bolts, remove the old support.

Do not forget to mark the old cushion (its top) with any mark so that when installing a new rubber support you do not "guess" how to install it correctly.

Then put a new rubber support, for a start, just tightening the bolts so that everything coincides everywhere, and then tighten them, but not completely. After the preliminary tightening, release the tension on the hoist rope or lower the jack and tighten the bolts completely. Before assembly, clean the bolts (if there are traces of rust, then use a metal brush) and lightly lubricate the threads with any grease, for example Litol-24 or graphite grease.

At the beginning of the checkpoint, the box is hooked with a hoist cable or jacked up for insurance.

When replacing the three engine mountings of the VAZ 2109, the left pillow is not very convenient for work and there are a number of difficulties when replacing it. The dismantling of the fasteners is interfered with by the starter housing, so there are two ways to do this. Either release or remove the starter (a few minutes spent will greatly facilitate the replacement of the left side engine mount), or unscrew the rubber mount bracket mounting studs from the "body" of the gearbox.

Often the studs come out on their own when the nuts are unscrewed, but if the stud remains in place, then to unscrew it by locking two nuts against each other, then unscrew the stud by the lower nut. With a long bolt securing the pillow to the side member bracket, there is usually no difficulty and if the rear support is not squashed, then the bolt comes out freely after unscrewing the nut.

When installing a new left engine mount, for an accurate hit of the studs on the thread, the gearbox must be slightly raised with a hoist or jack. Then insert a long bolt, squeeze all the fasteners, lower the jack and then tighten everything completely. If the starter was released or removed, then everything is put into place.

Engine mount vaz 2109 rear gearbox

With the help of the hoist, the gearbox is hooked or a jack is placed from below. Then the bolts of the pillow bracket connected to the gearbox and the support body itself at the point of attachment to the body are "torn off", then the power unit rises slightly. Now the bolts are fully released and the box support is removed.

When installing a new pillow, you need to "play" a little with a jack for exact alignment of the holes, this is especially important when installing the vertical mounting bolts of the pillow. Often, due to some misalignment in these connections, the threads are broken during installation. When these bolts are baited, then you need to center one of the holes with any conical object of a suitable diameter, and insert the bolt into the second hole and "catch" the position when it freely goes along the thread. Then put the second vertical bolt as well. Having acquired all the bolts, then they are evenly tightened, the jack is removed and all the bolts securing the rear gearbox cushion are pulled again.

Actually, that's all. The protection is put in place and this is where the replacement of the engine cushions of the VAZ 2109 ends. The whole process of work, taking into account the preliminary removal and subsequent setting of the protections, takes about 3 hours. It will be lucky if nothing has soured anywhere, for example, studs, bolts in the bushings of the engine mounts, and so on.

Checking the condition and replacing the rubber cushions of the engine mounts

Engine mounts rarely require attention, but in the event of damage or signs of aging of the material of the rubber pads, they must be replaced immediately, otherwise the increased vibration may cause failure, wear or damage to the components of the vehicle's transmission line.

During the check, the engine must be slightly raised so that its weight can be lifted from the supports.

Jack up the vehicle and place it on struts, then place the jack under the engine oil pan. Place a block of wood between the jack head and pallet to distribute the load. Raise the engine carefully by lifting the weight off the feet.

Never carry out any work with a vehicle that is being jacked up!

Check the rubber pads on the feet for cracks, signs of hardening, or separation from the metal backing. Sometimes the rubber will crack and split right down the center of the pad.
Estimate the relative play between the support plates and the motor body / frame (use a large screwdriver or pry bar as a lever). If there is play, lower the engine and tighten the mountings.
To slow down the aging process of the material of the support cushions, they should be covered with a protective compound.

Disconnect the negative cable from the battery, then jack up the vehicle and support it (if not done before).
Raise the engine slightly with a jack or winch (be careful not to hit the radiator or fan shroud).
Loosen the through-bolt nut and remove the support-to-frame bolts.

Car supports for strength are calculated by the designers depending on the load that they perceive:
- Regardless of the position of the machine, whether it is moving or standing still, the support experiences its weight.
- She experiences one load at the start of the car, the opposite in force load acts when it moves back.
- The device extinguishes the negative effects of forces on the car during sudden braking and acceleration, hitting a large pothole or hitting an obstacle and other alternating loads.
- Products are made from natural rubber, SKI-3 rubber, special premium grade of the first group, special glue and high-quality steel.
- The support can work correctly in the temperature range (+70) - (-45) degrees.
- All this suggests that the replacement of the VAZ 2109 engine mounts is carried out with a similar factory-made kit.
- When buying, you need to give preference to products that have positive reviews from buyers.
- In a VAZ 2109 car, the engine is mounted on three elastic mounts in the engine compartment. The right support is attached to the engine bracket, and the rear and left support to the gearbox housing bracket.
  The last two have similar designs.

Removing the rear support VAZ 2109

The set of rear supports can be with a bracket or not. The product is a cast one-piece element, with all the necessary holes for mounting the support.
The ribs located on its inner part help to increase the reliability and rigidity of the product. The upper motor retention bracket is the intermediate piece between the flex rod and the motor mount.
With its help, the angle of attachment to the body of the engine support changes and the structure is strengthened:

Tip: If the engine mount was purchased without a bracket, the part must be rearranged from the old device. For this, its bolt is unscrewed, and the bracket is installed on a new support.

How the replacement of the engine support of the VAZ 2109 is done correctly can be clearly seen in the video.

An available tuning element, which can be used to mount the motor, to make it stiffer, consists in replacing the factory standard support with a product with a rubber support part and a more rigid body.
This device allows you to:
- Reduce the maximum displacement of the engine when it is braking, abrupt start of the car, hitting bumps.
- Prevent transmission from shutting off.
- To increase the resource of the drives of the driving wheels in the exhaust system.
- A striking tuning piece will be installed under the hood.
