Despite the fact that the washing machine is constantly in contact with water, there are parts in it that should not get moisture. To a large extent, this applies to drum bearings, which wear out quickly when the grease is washed out. The bearing protects the seal against water ingress - an airtight seal.
Some users are wondering: is it necessary to lubricate the oil seal of the washing machine? Let's get it right.
Why lubricate an oil seal in a washing machine
To begin, consider the device and the principle of operation of the seal. Not a single washer is complete without this detail.
This rubber seal ring protects the bearings at the joints from water. For high-quality sealing, the seal of the washing machine tank should sit as tightly as possible. That is why it is recommended to replace it simultaneously with bearings.
A metal sleeve passes through the central axis of the tank, which during rotation contributes to wear of the gland. To prevent this from happening, it is necessary to use a water-repellent grease for oil seals.
What grease for oil seals to choose
Some users use folk remedies, such as oil or fat. Of course, this seems to be more economical because a grease that meets all the standards is expensive.
Dear users! Do not forget: saving on lubrication, you reduce the life of the gland. Subsequently, you will have to spend money on new parts and replace them.
Before replacing the oil seal, we will figure out what lubricant to choose.
Properties that a grease should have:
- Water repellent.
- No aggressive chemical components. Otherwise, under their influence, machine parts will be destroyed.
- Resistance to temperature extremes.
- Viscosity - for long service life.
Experts recommend the use of silicone water-repellent grease for LIQUI MOLY Silicon-Fett oil seals. It is able to withstand temperatures from -40 ° C to + 200 ° C. It is considered the most effective of all presented.
Other means are also popular. What else can grease the oil seal in the washing machine, read below.
Anderol for washing machines
Italian-made lubricant has a neutral chemical composition, water-repellent properties. Withstands temperatures up to + 190 ° C. Perfectly retains its properties when heated. Suitable for all types of oil seals.
Ambligon
Ambligon - grease for oil seals from the Italian manufacturer. The product perfectly retains its properties when exposed to temperatures from -28 to + 192 ° C. It has water repellent properties, chemically inert. Packed in portions in syringes of 2 ml, and in packages of 100 g.
Litol-24
Multipurpose grease is water resistant. Unlike non-professional means, it does not harden when heated. It is able to withstand temperatures from -40 ° C to + 120 ° C. Chemically and mechanically stable.
Litol-24M
The product has a water-repellent effect, reliably protecting components from corrosion. Withstands temperatures in the range from -40 ° C to + 120 ° C. Compatible with other lubricants, does not compact in water, mechanically stable.
TsIATIM-221
Multipurpose homogeneous grease.
Replacing the stuffing box in the washing machine requires the grease to withstand temperature extremes. TsIATIM-221 is able to withstand from -60 ° C to + 150 ° C. It is successfully used in friction units, does not lose its properties during boiling.
However, there are also disadvantages: the lubricant is hygroscopic, therefore, absorbing moisture, it condenses and loses its properties. In addition, it can not be used together with other means. Chemically inert.
Make your choice and get the right lubricant.
Now consider how to change the oil seal.
We make a replacement
Let's see how you can get to the gland. Here are the steps for you.
- Having disconnected the machine from the network and communications, drain the remaining water from the drain filter. It is located under the front panel, behind a small hatch.
- Remove the two screws on the back to remove the top panel. Now unscrew the screws around the perimeter of the rear panel, set it aside.
- Remove the drive belt from the drum. Having locked the pulley with the handle of the hammer, unscrew its central bolt and remove it from the tank.
- Disconnect the wiring that can be attached to the drum. Usually it is fixed with plastic clamps, so use wire cutters.
- Having disconnected the motor wiring, unscrew the fixing bolts and pull the electric motor out of the housing. Also unfasten the wires from the heater.
- Remove the bolts of the upper counterweight of the tank. Put it aside.
- Pull out the detergent drawer by pressing the center latch. Remove all bolts that hold the control panel. Having opened the plastic latches, remove it and put it on top of the case.
- Loosen the filler valve clamp and disconnect it from the tank. Pull out the powder hopper with the filler valve. To do this, unfasten the wires from the valve and unscrew the fastening bolts from the back.
- Remove the pressure switch hose, which is usually attached to the tank.
- Open the hatch door by bending the sealing rubber, remove the external clamp. Insert the cuff into the tank. Loosen the screws of the UBL lock by running your hand behind the SMA housing, pull out the lock and unfasten the wiring.
- Unscrew the screws along the perimeter of the front panel, pull it up and set it aside.
- Remove the counterweights from the tank by unscrewing the bolts.
- Unscrew the shock absorbers, remove the tank from the hooks and pull it out.
You have dealt with the dismantling of the tank. Now we will figure out how to get and put the stuffing box in the washing machine.
- Remove the screws around the perimeter of the tank. Use a screwdriver to release the latches and remove the upper half.
- Having hit the bushing several times, knock the drum out of the tank.
- Remove the gland by prying it with a screwdriver.
Before installing the oil seal correctly, apply grease. Start lubricating the outside with a thin layer. With the seal in place, use a syringe to apply lubricant to the inside.
How to change and lubricate the oil seal, you understand. It remains to assemble the car and enjoy its smooth operation. A video on the topic will help you:
