We are learning how to replace the crane with the axle box

If you are interested in how to unscrew the crane from the mixer, then you should be sure that this valve is there, and not a cartridge or a ball. Although, it is quite simple to determine - if two lambs or two levers are used for adjustment, it means that you are on the right track.

But here, not everything is so simple, since the axle boxes can be different - so, it can have a ceramic pair for adjusting the flow, or a worm gear for pressing the valve. Now we will figure it out together, carry out repair work and see a thematic demonstration of the video in this article.

Cranes

Note. If you have a joystick-type mixer (with one lever), then there, most likely, there is a plastic or ceramic cartridge as a stop valve, and in some cases (for expensive models) a ball valve. The question of how to change kranbuksu on the mixer, is relevant only in cases where we have a two-valve (two-lever) mixer, as well as in the through and single taps with a spout.

Differences

To figure out how to change the crane in the mixer, or even better, to repair it, you need to understand what it consists of and how it works, that is, how it is used to regulate the water flow.

The entire repair kit is divided into movable and fixed parts, where the first includes a retaining ring or bracket, a rod with a fork, a sound suppressor and a top ceramic plate with a hole. Fixed parts include the case itself, the lower ceramic plate with a hole and a rubber ring for sealing. (See also the article Flexible wiring for the mixer: features.)

You have probably already noticed that the holes in the ceramics are not located in the center and this factor allows you to regulate the flow of water. That is, when the holes coincide, a full passage opens, but when the upper plate rotates around its axis, the holes gradually shift relative to each other, which reduces the passage until it is completely closed.

The rubber seal does not allow water to break through to the sides, but it flattens over time and then the question arises about how to change the tap of the bush in the mixer.

In the case when during the closing-opening of the valve it is necessary to make a lot of turns (from 5 to 10), this suggests that there is a stop valve with a worm mechanism. Despite the fact that the replacement of Kranbuksy in the mixer of this type is made almost equally with the ceramic version, however, its device is somewhat different.

In this case, the rod serves as a piston, which rises and falls with the help of a worm gear, but in order for water not to flow through this node, there is a fat chamber there.

Occasionally, the cause of the failure of such a mechanism is thread wear of the worm, but in most cases it is the wear of the rubber gasket on the piston, so replacing the cock-axle box in the mixer is not needed here - simply changing the gasket (valve).

Repair work

Note. If you decide to make any repairs with a mixer in the kitchen or bathroom, you definitely need to turn off the water, as required by the instructions. In most cases, this can be done through a common cock at the water meter.

• We first need to remove the valve, how to unscrew the Kranbuchs on the mixer is possible only after its dismantling (interferes). To do this, use a knife or screwdriver to hook a decorative cap in the center of the lamb and remove it, underneath there is a bolt that needs to be unscrewed and then we will remove the valve. If you have handles, then such a bolt, as a rule, is located under the lever on the body of the handle (it is also closed by a plug).
• Now we need to remove the locknut, twisting it counterclockwise, only this must be done carefully so as not to scratch the casewith. Often, there may be another decorative nut over the locknut, which in most cases can be unscrewed by hand. Now you can simply pull out the valves, but sometimes for additional fastening there is still a lock ring - dismantle it, since it will be possible to remove the cock box from the mixer only after that.

• Now you can just go to the store with the locking mechanism removed and buy the same, good, its price is low, but you can save yourself from buying if you disassemble it and repair it. To do this, remove the retaining ring from the stem and squeeze the ceramic pair together with the gasket from the body with a rod. If there is a raid on the case, then you will need to hit the end of the rod with a screwdriver or pliers.

• In order to eliminate the leakage, you need to increase the thickness of the flattened ring, but since it is impossible to do this, we simply increase the length of the inner axle box.. To do this, look at the photo above - there you see where to stick two or three layers of electrical tape to increase the thickness of the upper ceramic plate. In addition, a self-made washer made of copper wire can be inserted under the rubber sealing ring, as if to increase the thickness of the gasket. (See also the article How to choose a sink: features.)
• Replacing the rubber valve in the crankshaft with a worm gear will not cause any problems at all.. To do this, unscrew the bolt and washer and change the valve (you can even on a homemade, made of thick rubber).

Conclusion

As you can see, with your own hands you can not only replace the crane, but also repair it, without wasting time and money on going to the store. But I would like to warn you - if you still want to install a new valves, then be sure to go to the store with the old sample - such nodes can be of different sizes, so it is better to be safe.
