What is a bearing in a washing machine

Order of actions when replacing with your own hands the bearing of the washing machine with front loading

In order to carry out such work, it is necessary to prepare the tools that will be useful in the first place

During the work, the following tools and materials are used:

How to Change the Bearings in a Washing Machine

For the final stage of the work, we will need: new bearings, glands, silicone sealant, aerosol and lithol or other type of similar grease. Consider the sequence of operations step by step.

Tip! If you do not have special tools, you can use a hammer and core to tap the bearing out. It is important to apply blows strictly horizontally all over the bearing surface, otherwise it can “enter” crooked or deformed.

And if some parts are difficult to unscrew due to salting, you can use WD-40 spray to unscrew them. The product can dissolve all compounds except metal.

Peculiarities of repair with vertical loading

Here, the drum is supported by 2 half axles and 2 bearings. With such a reliable design, they fail infrequently, usually when there is some other failure.

Often spoiled by water penetrating through a faulty oil seal. Rusting, steadily clogged with dirt, the bearing eventually fails.

It’s much easier to repair these machines. With the connections disconnected, the 2 side covers on the body can be removed and the work front is accessible.

The bearing on the side without the drive pulley is the first to be replaced. To do this, the support, a complete set of bearing and oil seal already sealed in the housing, is removed.

The stuffing box seating area is cleaned, along with the shaft itself. It is important when fitting a new bearing that misalignment of the sealing ring be avoided.

Otherwise, it will not be able to prevent fluid leakage, which will cause a new bearing failure.

To change a caliper from the motor side it is begun with removal of a belt and a pulley of a drum. Then it is a turn of a ground pad. Then unscrew the caliper. Clean the shaft and the seat, as in the first case.

Replace the oil seal in its proper place and screw in the caliper. It is not necessary to apply great effort, because the thread is made on plastic. Assemble in the reverse order, as usual.

Also on our site we have a separate article in which the process of replacing the bearings in the Indesit washing machine is reviewed in detail.

The preparatory stage

To replace the bearing unit with your own hands is not easy, but it is quite realistic, if you do not experiment and be very careful. When in the slightest doubt, it is better to apply to professional repairers, so as not to aggravate the problem and not to provoke a major repair. So first read the instructions and assess the degree of difficulty of the work to be carried out.

  • First check again the condition of the bearings. Unfold the drum and listen. If there is a rattle, a knock and a fast stop, start disassembling.
  • Go behind the machine and unscrew the two screws that hold the top cover. Then go back to the front and gently move the upper part away from you. Once the latches are released, you must remove the cover and set it aside.

As a side note! The removed cover can be turned over and used as a support for all removable small parts and fasteners to prevent them from being lost.

  • Slightly tilt the body back.
  • Pull out the external dispenser by pulling it abruptly.
  • Remove the screws that hold the front plate on both sides of the enclosure, as well as the screws on the powder collector.

The preparatory part is over. All that remains is to take the tank out, holding it with one hand and removing the springs on both sides with the other. Then we put the plastic container with the cross upwards on a soft surface and start dismantling the bearing unit.

Symptoms of problems with the oil seal

The water hitting the rubber destroys it, but very slowly. Because the machine does not show any sign of trouble for a long time. But as soon as the fluid reaches the metal parts, it begins to oxidise and break them down, flushing out the working oil. That can lead to rusting of the bearing and shaft. Therefore, if there is even one of the following signs, you should start with replacing the packing:

Warning! In these cases, most often requires replacement of not only the packing, but also the bearing. Therefore it is better to buy spare parts after the machine is disassembled and the real reason of malfunction is found.

What bearings are in the LG washing machine?

The reason for this is that the damping elements are defective and can no longer absorb the centrifugal force of the machine. This is why the dispenser “jumps” about the room when washing. If you turn a blind eye to the problem, it is easy to “lose” the bearings after a while.

If you can feel the imbalance, it is safe to say that the bearings have already begun to fail. After that, rotate the drum firmly. If it moves freely with a slight humming noise, everything is fine. If you hear obvious noise, and the drum rotates unstably, the bearings need to be replaced.

Diagnosis with a partial disassembly of the washing machine

To finally make sure that it is necessary to dismantle the tank and replace the bearings, you need to partially disassemble the washing machine. In fact, it is enough to remove the back panel. It is important not to forget to completely de-energize the machine, disconnect the water supply and drain hose before starting work.

The sequence of actions directly depends on the brand of a particular device. In the case of popular models of Ariston washing machines, it is enough to unscrew the bolts that hold the top cover, slide and remove it. After that, it remains only to unscrew the screws around the perimeter of the back panel and remove it.

Next, you need to carefully inspect the inside of the washing machine, for convenience you can move it away from the wall and move it to a well-lit place or use a flashlight. Leaks from the center of the bowl are a cause for concern.

The purpose of the node and the consequences of its failure

The bearing unit is an important part of the washing machine. On the one hand, it ensures a secure attachment of the drum to the tank, on the other hand, it does not prevent the drum from rotating freely. The way the bearings are installed and the configuration of the unit can vary significantly and depends on the type of machine and its manufacturer.

In most models of washing machines from reputable manufacturers, such as Indesit, Samsung, Bosch and others, the drum axis rotates on two bearings. They differ in size. The outer one is subjected to maximum load more, while the inner one is less. In the obligatory order the knot is closed by a sealing collar, which prevents water leakage from the tank.

The bearings ensure the smooth rotation of the drum, they also protect the tank from mechanical damage. In no case can you use the washing machine, if there were signs of a breakdown of this unit. A loose shaft can cause the failure of a number of parts, up to and including the physical destruction of the tank, which will entail costly repairs.

Dimensions of bearings and glands for washing machines

Two types of bearings are used in the washing machine:

  • metal. the most popular type due to the low cost, is used in the washing machine of economy class;
  • plastic dustproof, the only disadvantage of which is a higher price in comparison with the metal ones. It has excellent technical specifications, accompanied by an excellent quality. A characteristic feature of the structure is a two-layer structure that has a metal base, covered with protective plastic.
