Does your washing machine make a lot of noise during operation? Do you hear extraneous sounds and squeaks? Such signs may indicate bearing wear. In most cases, they need replacement, but even when installing new parts, they are thoroughly lubricated.
What kind of grease is used in bearings and what properties it has, you will learn in this article.
Right choice of
Before you start work, you need to find out what kind of grease to lubricate the bearings. There are only a few types of lubricant that meet these requirements:
- They are moisture resistant. Since the CM shaft parts are constantly in contact with water, you need a water-repellent bearing grease. If the water washes out the agent by which the bearing slides without wear, it will soon wear out.
- They have heat resistant properties. Hot water in the tank and heating of the shaft during rotation can deprive cheap grease of its properties. Then water will get on the parts and corrosion will begin.
- Should not aggressively affect the rubber. Otherwise, the seal may become hardened, resulting in water leakage.
- Bearing grease should be thick. Otherwise, it will simply leak out during operation.
Many users are interested in whether bearings can be lubricated with Litol and other automotive lubricants. It is undesirable to use such means. They serve as poor protection, so soon you will have to repair the washer again.
Which remedy should you choose?
AMPLIFON is offered by Italian manufacturers MERLONI. This is a moisture resistant lubricant that does not wash out with water.
Anderol is known for its convenient dosage of 100 grams in jars or syringes for two applications. Manufacturers of washing machines Indesit release the product.
STABURAGS NBU 12 is a waterproof, regenerating bearing grease that will provide a high level of wear protection. Heat-resistant and resistant to aggressive environments (washing solutions).
LIQUI MOLY “Silicon-Fett”. Silicone grease for washing machine bearings. It has a thick texture, heat resistance (withstands from -40°С to +200°С). Adheres well, providing a high lubricating effect.
Huskey Lube-O-Seal PTFE Grease. Sticky, homogeneous texture, not washed out even with a water jet. It is heat-resistant, withstands from -18°С to +117°С. High corrosion protection.
What is better to lubricate
Some people think that the oil seal is processed first, while the thrust bearing does not need to be lubricated. This is true only if you bought the original part.
Note! When machining the oil seal and bearing, never mix lubricants, as they may not be compatible with each other.
Stages of work
You need to start by disassembling the washer and dismantling the bearings. For any brand and model, the disassembly principle is almost the same.
Start by removing the panels
Remove the top cover: remove the screws on the back that hold it in place. Then push forward and out of the way.
Remove all screws around the perimeter of the back panel that hold it in place. Now move on to the front of the case.
- Pull out the detergent drawer by pressing the latch in the center.
- Unscrew the bolts that are behind the tray, as well as on the opposite side of the control panel.
- Release the plastic clips and remove the control panel. If you decide to unfasten all connections, take a picture of their location in advance.
- Open the hatch door. Bend the cuff and remove the clamp. Fill the sealing rubber inside the tank.
- Remove the two screws holding the sunroof lock. Unfasten the wiring from the lock.
- Remove all screws holding the front panel.
Remove parts from the top of the tank
Remove the upper counterweight by unscrewing the mounting bolts.
Now you need to get the powder receiver. Use pliers to open the clamp that secures the nozzle to the cuvette. Disconnect the tube. The fill valve hoses are also attached to the powder receiver. You can detach them, but it’s easier to remove them with the valve. For this:
- Unscrew the bolt on the back wall holding the valve.
- Disconnect the wiring from the valve and pull it out of the body along with the cuvette.
Also unfasten the pressure switch hose that is attached to the tank.
Move to the front of the case
Remove the front counterweights of the tank by unscrewing the bolts.
If the heating element of your washing machine is located in front under the tank, disconnect its connectors. Then, using wire cutters, remove the wire clamps and remove it from the tank. Loosen the drain hose clamp screw. Remove it from the tank.
Be careful, water may spill out of the nozzle.
Disassemble from behind
Remove the drive belt by pulling it to the side and turning the pulley.
If the heater is located at the back of the car, unfasten its wiring, as well as the engine connectors. Now unscrew the motor bolts and pull it out of the housing.
Release the plastic clip and unfasten the pressure chamber that is attached to the tank. Loosen the shock absorber bolts. Raising the tank, remove it from the hooks, pulling it out of the body.
Lay the tank on a flat surface. Remove the sunroof seal by removing the inner clamp. Turn the tank over and remove the pulley by unscrewing the central bolt. Pre-lock it with a wooden plank.
Separate the two parts of the tank by unscrewing the screws around the perimeter. Take out the drum. Now you have reached the bearings. Now you will learn how to properly lubricate the bearing in the washing machine.
Shut down the work
Remove bearings from tank. To do this, pry the gland with a screwdriver and pull it out. Install a chisel on the outer race of the bearing and, tapping with a hammer, knock it out of the tank. Do the same with the second element.
If you have decided which bearing grease to choose, then after cleaning you need to remove the protective cover of the part. A tool is laid inside.
But how is a non-separable, sealed bearing lubricated?
- Take WD-40, spray it on the parts and wipe it well with a rag.
- After cleaning, you need to open the lid, but it does not lend itself.
- Fill the inner ring of the part with a plastic bag.
- Take a tube of grease, cut off the neck so that it is equal to the diameter of the inner ring of the bearing.
- Install the tube on the inner race and squeeze out the grease until it starts to come out from the opposite side.
- Then start swirling the inside of the bag to distribute the lube. If you have been wondering if sealed bearings need to be lubricated, now you know what is necessary and possible.
- Remove excess. Install the item in place.
How to lubricate the oil seal
Now about how to restore the oil seal with your own hands. Of course, a worn oil seal cannot be repaired. Remember a simple rule: if you decide to replace one element, you need to change the entire set if you want to make a quality repair.
It is better to lubricate the gland with a syringe. Fill the inner groove of the gland and install it in place. It remains to assemble the SMA in the reverse order.
