The axle box crane is the moving parts of a valve valve assembled in a single removable structure. Due to this, it can always be replaced in the event of a malfunction. Replacing the faucet in the mixer is simple, and it will be carried out by anyone who can hold a wrench in their hands.
The purpose of the plumbing design is to open, regulate and block the flow of water.
To eliminate leakage, you just need to change the crane box, which is easily twisted from the socket of the mixer.
Preparation for work
Before replacing, you need to prepare open-end wrenches or an adjustable wrench. You must have a special plumbing tape to seal the threads, a screwdriver to unscrew the lamb (valve)
Replacing the faucet in the bathroom faucet requires special care.
The sink should be protected with a piece of cardboard or plastic. This is done to protect the plumbing from falling crane-axle box or wrench. And also to avoid falling into the drain of metal parts.
Work errors
Replacing the faucet box in the mixer is often error-prone. Do not use excessive force when unscrewing it. There are cases of thread contamination with rust. Then you should moisten this place with acetic acid or special cleaning agents.
Observe the prescribed precautions. When twisting, excessive efforts lead to deformation of the parts. You can even damage the threads. And this will already entail the cost of buying a new mixer.
Self replacement
If a faucet drips, you can call the plumbing - this is the easiest option. But replacing the faucet box in the mixer with your own hands is not a problem.
But what if a person has never performed this operation and is afraid to do something wrong? In this case, you can read the instructions on the Internet and gain the first experience in replacing the axle box in the crane.
Old type axlebox with locking rod
A rubber seal is attached to the end of the stem to block the flow of water.
The advantages of this type of crane box are easy and cheap repairs. It is enough to change the compression rubber seal at the end of the stem.
The disadvantage is that this procedure has to be done quite often. At the same time, the crane is noisy due to vibration of the gasket, especially when it is worn.
The principle of operation of ceramic crane boxes
They are in great demand. Advantages - noiselessness and reliability; five-year plans and more can work. The wear period depends only on the quality of the water and timely cleaning of the filter trap from dirt and debris. However, ceramics are more expensive, and in case of failure the axle boxes require a complete replacement.
The principle of operation of the ceramic axle box consists in combining the holes of the rotary ceramic plug with the hole on the body. When combining the holes, the flow of water rushes through the tap.
Parts are leakproof due to tight fit. That is why the quality of water, in which there should be no solid particles damaging the surfaces of tightly fitting parts, is so important.
It is easy to distinguish a crane box on a gasket from a ceramic one. Ceramic closes in 2-3 turns, and at the same time a hard stop is felt. After closing the valve, the compression gasket can be tightened further without a hard stop. And when you open, you need to make a few turns before the water goes.
In order to buy a crane box, you need to know the desired type, thread size and manufacturer.
The best option is to take the old part, the lamb and the screw fastening with you to the store. In this case, the sellers will choose the same, or tell you where to buy it.
When purchasing a product, it is necessary to check whether the "native" lamb and screw are suitable for it.
Dismantling of the axle box
Before starting work on replacing the crane box in the mixer, the water inlet to the apartment or house should be blocked. Locking devices are located next to the meters. If they are not in the apartment, you will have to call the plumbing to turn off the general water supply to the riser.
Regardless of which crane the crane is replaced in the two-valve mixer, all water entering the house is turned off.
After the water is shut off, it is necessary to open the taps all the way. After the residual water drains, you can begin to work on the analysis of the faulty axle box.
The flywheel is removed first. To do this, the protective cap is opened and the flywheel mounting screw is loosened.
After that, take a wrench and gently loosen the thread. Then the axle box is unscrewed by hand.
The diagram of the crane device and its details are shown in the figure.
The new axle box is installed in the reverse order. The entire repair procedure is a replacement of the axle box. Or a seal on the stem, if the crane is an old type axle box and is still suitable for use.
At the end of the work, you need to open the water and check whether the seals are leaking, and how the plug works.
Replacing the axlebox in the Grohe mixer
The Grohe mixer is in high demand due to its reliability. He can serve for a very long time.
The only difference between Grohe is that the lamb is not attached with a screw, but with a latch. In order to remove it, you need to squeeze the latch and pull the lamb.
The dismantling and replacement of the axle box faucet in the Grohe mixer is standard, and it is described above. Having unscrewed the malfunctioning axle box valve, take a new one, screw it in thread, tightening to the seal. But don't be zealous.
Then put a latch on the spline mount, a lamb on it and, having pressed on it, fix it.
Conclusion
In order to properly replace, you need to know the type and size of the axle box crane.
If the product is an old type, then only the compression gasket on the stem must be replaced. The axle box crane is removed, a new gasket is inserted, and the product is installed in place.
In order for the ceramic box crane to serve for a long time, it is necessary that a filter trap is necessarily installed on the eyeliner.
