If the bearings do not make noise, then you do not need to change, the gland can also be left with the old one, only slightly grease the edge with lithol.
The "wheel", which is also a pulley, should dream without problems if you unscrew the bolt with which it is screwed. Having removed the pulley, the shaft can be easily removed, while the bearings remain in the hub (they are pressed into it).

The most difficult thing is to remove the rest of the cross from the drum. It is screwed on with three stainless bolts, the threads of which are lubricated with “anti-torsion”, and the heads of the bolts lick off easily. To make them easier to unscrew, you need to heat the crosspiece to two hundred degrees, then the silumin expands and the “anti-scrolling” melts. The wrench must be a ring wrench with six sides, otherwise the slots on the bolts will merge.

The crosspiece of the drum is the basis for the operation of the moving parts of the washing machine. Any defects in the crosspiece can affect the operation of the machine in such a way that it will lead to the destruction of the bearings, drum, heating element, and the tank body. That is why if you have any suspicions or you know about problems with the cross, you need to immediately start repair work.

Generally speaking, all the reasons for the breakage of the cross are reduced to the carelessness and carelessness of the user of the washing machine, who did not listen to its work in time. In this case, you don't even need to listen too much, because if the machine is brought to a breakdown of the drum cross, this means that it has been working for some time with a terrible creak and metal grinding. What causes the crosspiece to break?

  • Bearing defect;
  • manufacturing defects;
  • hard water;
  • unsuccessful repair.

The main reason is, of course, the untimely replacement of the bearings, which led to their complete destruction, which in turn led to damage to the crosspiece shaft.

Note! A destroyed bearing cage and balls during the rotation of the shaft scratch it very much, leading to a depletion, which in turn leads to the fact that you cannot put a new bearing on this shaft, replacement must be done on time.

Factory defects are less common, although this is not so uncommon on typewriters from Italian firms. Why is this happening? Maybe the reason is the quality of the alloy or the lack of quality control in the production of components. History is silent, but the fact remains, the crosspiece is destroyed.

Image - DIY lg washing machine cross repairEven in a perfectly functional washing machine LG or any other, the crosspiece can deteriorate from constant exposure to hard water. Although, of course, hard water is a secondary cause, since it makes it difficult to rotate the drum, and this in turn damages the bearings, which are already damaging the spider shaft.

Also, unsuccessful repairs can be the cause of the crosspiece breakage. This is generally a separate topic for conversation, since there are different craftsmen who are trying to remove and change the bearing of the cross-piece. Some, trying to remove the bearing with a grinder, cut off the shaft, others lick the thread, trying to unscrew the mounting bolt, in general, the meaning is clear, if the hands do not grow from there, there is nothing to say!

Perhaps only an experienced craftsman will be able to determine whether or not it is worth repairing the cross, it needs a replacement, or you can try to reanimate the part. It is necessary to study the development of the shaft, the condition of the thread, therefore we recommend that you be extremely careful and if you have the slightest doubt about the serviceability of the shaft, contact the service center for advice. A faulty crosspiece must not be left in operation.

If the bearings of the crosspiece of the LG washing machine are out of order and the shaft output is small, then there is no need to change the entire part, and even more so the crosspiece together with the drum, as representatives of the ARDO service centers offer us. Such repairs will cost us almost more than a new washing machine; new bearings can be supplied separately. But if there is obvious damage to the shaft of the crosspiece or its elements (especially the seats), the replacement of the part cannot be avoided.

So, the repair of this part of the LG washing machine or any other is possible only if the bearings, which are located in the bushing of the tank lid, are damaged. Separately, I would like to note the fact that some masters do not install original, inappropriate bearings that are not designed for a given load. As a result, the bearings are destroyed, and repairs have to be done again. To avoid this, you need to purchase bearings that will correspond to a specific LG washing machine (or another).Image - DIY lg washing machine cross repair

To change the bearings of the washing machine cross, you need:

  1. dismantle the old bearings from the shaft (since they stick to the shaft);
  2. remove old oil seals;
  3. put new oil seals;
  4. press in new bearings.

But as the saying goes, this is easier said than done. The main problem is related to the careful removal of old bearings from the shaft of the drum spider. Usually damaged bearings stick to the shaft seat so that it is extremely difficult to pull them out of there. You have to make an effort.

In no case should you hammer on the bearings with a hammer, trying to destroy the cage, together with the cage, you can damage the shaft, since it is made of soft metal.

Knocking down bearings with a chisel is also quite dangerous, although you can still use a chisel, but in a slightly different way. How can you proceed?

  • Take a grinder or drill.
  • Make cuts on both sides of the old bearings.
  • Then install a chisel in the cuts and knock the bearing off the shaft.

Image - DIY lg washing machine cross repairIn the presence of cuts, the bearings are easier to knock down, a lot of effort is not required, and therefore the risk of damaging the shaft is less. The most important thing is not to rush, because rush is the enemy of any business. Old oil seals must also be removed. Moreover, they are removed always and in all cases, even if it seems to you that the oil seals will still work. It is better to spend extra pennies on oil seals than to do a new repair of an LG or other washing machine soon because of them.

We put new bearings and oil seals in place of the old ones, assemble the car and rejoice. It happens that the bearings can hardly sit in the bushing or do not want to sit at all. In this case, you can warm up the steel sleeve a little with a blowtorch and carefully press in the bearings - they will keep dead! The crosspiece is attached to the outer wall of the drum by 6 bolts, in some cases by 3 bolts, unscrew these bolts, remove the crosspiece, put a new one and assemble the machine back.

Important! Some models of washing machines have crosspieces that are welded to the drum. Since the crosspiece is inseparable from the drum, we change it together with it.

Summing up, we note the repair of the drum of an LG typewriter or any other, or rather replacing the crosspiece is a very time-consuming business. The main problem is not even in the repair or replacement of the crosspiece itself, but in the long and tedious disassembly of the washing machine. If you are determined to get the job done, this article is for you!

A cross is called a part that, as it were, connects the drum and the tank. Thanks to the action of this part, the work of the moving part of automatic machines is ensured. There are bearings inside. The use in the manufacture of soft metals leads to the appearance of various deformations over time.It is not so difficult to make a replacement or repair if you know the rules exactly. It is easy to figure out how to remove the crosspiece.

Usually the part does not fail suddenly, unexpectedly. Bearing wear suggests the presence of additional noise during operation, hum. Bearings first begin to wear out, and then further destruction occurs.

What other reasons can there be for such a malfunction?

  1. Negative result of previous repairs.
  2. Using too hard water.
  3. The presence of a factory defect.

Most often, problems arise due to the fact that bearings began to wear out, but their replacement was not made in time. This destroys the entire drum spider.

If the bearing cage, their balls are badly destroyed, then during the operation of the device they severely scratch the shaft. The result is the emergence of the so-called development. The new bearing will no longer be able to fit on the same shaft. We'll have to replace both parts of the structure.

Cases with marriages are quite rare. The exception is the models of some Italian brands. The reasons are different:

  • Low quality alloy.
  • Lack of production control.
  • Components are produced with violations. What this or that model is made of is easy to find out from the accompanying documents.

Constant exposure to hard water can damage the crosspieces even on the highest quality products. In this situation, difficulties arise when the drum moves. This will damage the bearings. The result is a broken crosspiece.

In the case of an unsuccessful repair, everything is clear. Many people put too much effort, which makes the parts no longer fit for further use.

Only a technician with sufficient experience can tell if the device needs repairs at the present time. The condition of the thread and shaft wear are studied first. It is worth contacting the service center if there is the slightest doubt that the part is working properly. Defective crosspieces must not be ignored.

There is no need to change the entire part if only the bearings are damaged, and the output remains small. Repairing the washing machine cross will become quite expensive for the consumer, and the result will not be very noticeable. Another thing is when there are damages and are strongly visible on the surface of the part. For example, when the crosspiece burst.

The bearings themselves are located in the tank cover bushing. The behavior of some craftsmen deserves a separate discussion - they often put bearings that are not designed for the load actually present in a particular model. Because of this, the part is destroyed again, you have to re-turn to the services of specialists. It is recommended to independently purchase bearings that are suitable specifically for use in conjunction with a specific model of the machine.

Replacing the bearings at the crosspiece involves the following actions:

  1. Removing old bearings from the shaft.
  2. Removing old oil seals.
  3. Installation of new oil seals.
  4. Pressing in new bearings.

The main problem is that every action is carried out as accurately as possible. Old parts are often difficult to pull out of place without damaging other structures. You have to put in extra effort.

It is not recommended to make attempts to destroy the clip, for which the owner hits the surface with a hammer. This often contributes to damage to the shaft.

It is also dangerous to use chisels to knock down a part. It is allowed to use the tool, but you need to be very careful:

  • First, a grinder or a drill is taken.
  • Cuts are made on old bearings, on each side.
  • A chisel is installed in the cuts. The bearing finally knocks off the shaft.

It is the cuts in this case that simplify the repair. The main thing is not to rush, rush will prevent you from achieving the desired result when performing work. A mandatory step is the removal of the oil seals.They are removed in any case, even if their condition still seems normal. Upon completion of the work, new parts for Samsung and other models are put in place of the old ones.

It is important to ensure that the presence of a breakdown is identified in time. Then other parts of the washing machine will not suffer as much. Excessive noise during washing is the first sign of a malfunction. Sounds that were previously absent usually appear. At the first suspicion, it is recommended to contact the master.

It is recommended to choose specialized service centers. Or stores that work directly with manufacturers. The part is purchased from the same brand as the washing machine itself. The following brands have their own characteristics:

The easiest way is to work with machines that are available top-loading. In this case, it is not necessary to remove the tank, which greatly simplifies the whole process. But replacement requires the removal of the plastic calipers where the bearings are melted.

Some change only the bearing itself, ignoring the calipers. But this approach cannot guarantee that the minimum warranty period is maintained. Only a new caliper will increase the shelf life of the device as a whole.

In what sequence is the work carried out?

  • First, the walls of the washing machine are dismantled along with the drive belt. The pulley is unscrewed separately. Inside the caliper, bearings are located on both sides of the tank. Both details change in turn, but in the shortest possible time.
  • Calipers or hubs can be removed in different ways, depending on which model requires work. In some cases, the use of two screwdrivers with a lever is required. In other situations, you cannot do without a screwdriver.
  • The oil seal must be removed if, after carrying out the previous stages, the structure remains in place.
  • The landing site is thoroughly cleaned of any kind of contamination.
  • New parts are treated with special compounds for maximum protection. In the groove of the stuffing box, grease is applied to the bearings without fail.
  • The new hub is put in place along with the bearing, the second part assumes the same steps.
  • The machine is assembled in the reverse order.

When replacing bearings, this is the most common option. Most of the machines are supplied precisely with horizontal unloading. The tank has to be disassembled separately in order to perform the necessary work. From below, two shock absorbers are used as a support, springs are used on top, two or four pieces.

Before starting work, the machine must be completely disassembled. The procedure is individual, depending on the model, or the personal preferences of the owner, master.

For disassembly, you will need to dismantle the following units with parts:

  1. Front bar, if any.
  2. Front bar with hatch.
  3. The bottom panel, where the drain filters are located. Under it, there are often screws holding the front wall with the door.
  4. Cuff.
  5. Noise filter.
  6. Shock absorber.
  7. Drainage pipes.
  8. Counterweights.
  9. Motor part.
  10. Pulley.
  11. Drive belt.
  12. Back wall.
  13. Valve for fluid supply.
  14. Filler pipes.
  15. Dispensers for detergents.
  16. Pressostats.
  17. The dashboard is upstairs, with the board added.
  18. Detergent trays.
  19. Top caps.

Replacing any parts of washing machines requires some experience, this is a difficult category of repair work. If possible, it is recommended to contact the wizard for help. Self-performance of work is permissible only with confidence in one's abilities, a certain skill.

Replacing bearings and a cross is not a work option to start with with no skills at all, with zero preparation. Now it will not be difficult to find a specialist, the whole operation is performed at home, in just a couple of hours. It is only allowed to independently monitor the status of the device, stable operation.
