Description and replacement of engine cushions

The engine is the most important part of any car. Therefore, in the development of the body are based on the principle of protecting the motor from external factors. But irritants are also of internal character. This refers to the vibration produced when moving along irregularities. It negatively affects all units and nodes, which leads to a rapid deterioration of the mechanisms.

For its minimization, the cushions for the engine are installed. What are they and how to change them? We will talk about this in our article.

Description

Consider the domestic brand of the car. Replacement of the VAZ engine cushions will not cause any special difficulties, since all models of devices for such cars are unified. Since the manufacturer sets the same cushions on all cars, for car enthusiasts, if necessary, it does not become a problem to get them. In principle, for the domestic automotive industry, the possibility of interchangeability of parts is a characteristic feature. Due to this, there is no shortage with spare parts on the market.

The engine mount cushion is made of special rubber or rubber. Fastening is made on a metal base. So the details last longer and are durable and reliable. Rubber will perfectly show itself both in a frosty time, and in a heat. Therefore, the vagaries of the weather for her are not terrible. Atmospheric precipitation also does not frighten it at all.

Principle of operation

How the part works is easy to guess. Rubber extinguishes the bulk of the fluctuations due to its elastic properties. Therefore, the elements are not overloaded. Naturally, this does not mean at all that as soon as the engine cushions are replaced, it will be possible to dissect without consequences the bumps and pits at high speed. These parts, like any others, eventually wear out. And when used in harsh conditions, their ultimate strength can sometimes not stand. Of course, their purpose is to protect them from breakdowns. However, the driver must carefully and carefully treat his car, otherwise soon a new replacement will be necessary.

Characteristic signs for replacement

To understand whether replacement of engine cushions is required, listen to your car while driving. Is there any clatter in the space under the hood? It is especially clear when you are driving on an uneven road.

If there is a knock, it should be diagnosed as soon as possible. For this, as a rule, it is required:

• Install the car on special supports;
• Raise the unit in such a way that it does not come into contact with the cushions (a jack is used for this);
• Examine the cushions for the presence of cracks or loopholes between the rubber and the base of the metal;
• Feel cushions - they should not be excessively hard;
• Check that all fasteners are tightened properly, and that the rubber is well lubricated.

The procedure will not take more than an hour. But it will allow to find out, whether there are malfunctions in this part or not.

Replacing engine mounts

If a fault is detected, then you can start working. Replacement of engine mounts VAZ passes in several steps. In total the motor is supported by four such details - from all sides, one piece. If a replacement is necessary, then all the pillows are changed at once, because only in this way is the optimum mode of future work ensured. After all, old and new elements may differ in their characteristics. Economically, replacing the engine cushions all together will also be more beneficial than changing them in turn as the problem arises.

So, the procedure consists of the following sequentially performed actions:

• The car is provided with a fixed state on level ground.
• From the generator belt drive is removed , bolts are loosened, attaching it to the body.
• The engine crankcase is raised.
• Unscrew the fasteners with the keys and remove the right pillow.
• Assemble in the reverse order.
• After that, the jack is transferred to the gearbox and lifted.
• The back pillow is removed and a new one is put in its place. Do not forget about the sequence of actions.
• Next, remove the mudguard of the motor. Through it you can get close to the front cushion and remove it.
• In the end, everything is set to its original place.

Conclusion

The replacement procedure is not difficult. This can easily be done by yourself. It is strongly recommended not to rush. Then all the elements will be installed correctly. Keys that will be needed for work: on 13, 15 and 17.

However, if the replacement did not help, and the vibration remains, then you need to "dig deeper". Faults can be associated with the CV joint. Then we can not do without the help of specialists. Thanks to modern equipment and skills, they will quickly cope with this problem.
