The bearing of the crankshaft, replacing the bearing of the crankshaft with their own hands. How to independently install the crankshaft bearing. Bearing crankshaft. How to remove the old and build a new one.

The crankshaft is a node of parts or a detail of a rather complex shape, which has necks in its design, contributing to the mounting rods. From these rods, the crankshaft perceives efforts with the subsequent transformation of them into the torque. Directly the crankshaft is part of the crank-rod device.

For the first time the crankshaft was described and constructed in the 13th century in the Ottoman Empire. To date, the crankshafts are made of the following materials: carbon, chromascular, chromonicelmolybdenum steel and alloys of high-strength cast irons. As you see, the crankshaft is very important and inalienable in any vehicle. And, compared with other parts of the motor, is quite high worth. Thus, even for the most ordinary foreign car, the price of the crankshaft will be about 15,000 rubles. It is because of this price, a variety of motorists are interested in the independent repair of this detail.

But as for the bearing of the crankshaft, he is the main link in this difficult system. All the load that the motor gives, the bearing takes on itself and transmits the rotation through the moving node.

Fabuated bearing, signs of failure

I would like to say that the crankshaft in the automotive vehicle is created in the form of a single and solid tool that cannot be disassembled. It is for this reason that the crankshaft is the most expensive detail in the engine, because it is impossible to replace any element that has failed, you can only replace the entire design as a whole. You can fix this device yourself only with balancing and rattling, however, such manipulations do not always give the necessary result.

The bearing, at first glance, is a minor and small element in the crankshaft system, which can not be carried out so important functions. However, it is he who is one of the most important details of the crankshaft. It is a bearing a certain assembly node, which is the foundation of the crankshaft and the main support detail. However, in addition to the foundation function, the bearing has another feature that is to rotate. As already mentioned above, the bearing takes on all loads and transmits it further through the moving knot.

Like all elements in car devices, the bearing is to wear and fails, as a result, it is necessary to replace it. However, malfunctions with this element occur not only because of the natural wear, as well as because of various external factors that directly affect a particular car. The cause of the crankshaft bearing breakage can be easily determined by specific sound, if during the operation of the motor, you hear a typical suspicious rustle.

In addition, when switching the transfer, pay attention to the sound that occurs at this point. If, during the transfer, you hear the growl, this indicates a malfunction of the crankshaft bearings. Also, gear shift can be made with a special complexity or with jerks. However, the presence of the above symptoms does not allow one hundred percent warranty that the bearing is faulty. In this case, a detailed consideration of the set of specific features of the vehicle is required, for example, remember, perhaps quite recently you conducted various repair work, which affected the motor directly, it may well be that the case here is not at all in the bearing and the causes of the car malfunction should be found at all in More place.

Which bearing is on the crankshaft

Bearing varieties There are no one dozen, and the type or type of bearing directly depends on the specific features of its application. However, at the moment, we are talking about car bearings, which there are only two types - rolling bearing and sliding bearing.

It is not a secret for anyone that car bearings are made in the form of a ring, around the circumference of which there are rolling tracks or gutters. During the direct operation of the device, with the help of these rolling tracks and combat the entire body. As for the principle of the bearing, it is also quite simple here. Immediately friction in the bearing happens when the surfaces are slipped, which come into contact. In this case, the bearing is made in the form of a smooth hull having cylindrical holes.

Preparatory work to remove the bearing

If the bearing failed, it is necessary to replace it, however, it is not so easy to get to him. To do this, you must perform the following manipulation:

1. In first, the car should be driven into the overpass.

2. Secondly, it is necessary to progress with the help of a handbrake, but it is even better to apply for this shoe.

3. Next, we dismantle the cardan.

4. Then disconnect the speedometer and the clutch cylinder.

5. Together with the clutch, you must disconnect the gearbox.

6. Now pull out the clutch basket.

Well, that's all, we got to the bearing. However, there may be difficulties here, as it is not so easy to remove the old item. There are several ways to extract the old bearing.

How to remove the bearing with the puller

To date, there is a special device that is intended to dismantle the bearing. Although the bearings in the car are quite a lot and they are all very different, for each of them, their puller is invented, with which the bearing removal passes simply and easily. However, there is a complete set of such pullers only in specialized service centers, and not everyone. But how, in this case, do the usual driver? Fortunately, there is still a way out of this situation. Each motorist can remove the bearing from the crankshaft on its own, without using the puller, but with the help of ordinary sweater, for example, chisel, inertial hook, and so on. Now we will look at these methods in more detail.

How to remove the bearing from the shaft without a puller, a detailed job

The first and most effective option for removing the bearing from the crankshaft is the method with a chisel. For this you do not need special knowledge or time, you just need to split the old bearing on the part, remove them and put a new item. However, in the process, it is important not to damage the crankshaft itself, which is not rarely occurring when using this method. That is why appropriate drivers usually use more gentle ways to remove the old bearing from the crankshaft.

The second method is no less effective than the first, even though the process itself will take longer, but you will be sure that you will not damage other elements of your vehicle. It is carried out with a certain inertial hook, which can be made by himself. By the way, to make it, you will need only a piece of any reinforcement or any metal rod. Its approximate length should be 40 centimeters, and the diameter is 8 millimeters. Also, you will need to find something like a cylinder - a certain hub or an asterisk, be sure to large.

An important requirement for this procedure is the fact that in the opening of our cylinder should be freely entering fittings. Then, you need to make a hook. For this, it is necessary to simply bend one end of the reinforcement by 90 degrees, and put on the fittings to put on the hub. Further, it is required from the opposite end from the hook to privary another piece perpendicular to the main rod, which would be the letter "T".

Now it should be proceeding directly to the dismantling of this bearing. For this, it is necessary to hook a hook for the inner clip. So, the asterisk walks along the rod and hits the limiter. If the rod is more often turned, the bearing will come out evenly.

The last option will be the extrusion method. If you look pretty, immediately behind the bearing you will find a hole in a small deepening. This recess must be filled with bread or solidol. Next, you need to take something like a bolt and score this bolt into the inner clip. Thus, pressure through solidol or bread is transmitted to the bearing and it is extruded by itself.
