The repair or replacement of water faucets and its constituent elements seems difficult and time-consuming for many. We hasten to change the plumbing fixture, not paying attention to the possibilities of its self-repair. The crane of the box with ceramic plates and its installation is no exception. Useful tips will help you learn about the malfunctions and methods of their elimination, self-installation and prevention of an irreplaceable site.

What is a ceramic crane with ceramic plates?
The basis of modern household plumbing fixtures is a stop valve with the possibility of adjustment and the necessary replacement during operation.
The work of the crane of the axle box is observed with the daily rotation of the mixer valve, turning the handle by one and a half or two turns. The crane of the axle box with ceramic plates is a detachable cartridge of shut-off valves, the principle of which is the displacement and alignment of the holes in the plates.
Externally, the crane of the box with ceramics differs from the element with a rubber gasket. Find out what a ceramic box is and how the device node is arranged during the repair or replacement of the element.
Helpful Tips
Let us say that the main elements of the crane of the axlebox are considered mobile and fixed parts:
Movable part
Housing in the form of a cartridge with holes for a spout.
Rotating rod with a head "square" / "slot".
Adapter with lock washer.
The upper plate.
Fixed part
Lower ceramic gasket for the axle crane
Sealing washer.
Judging by customer feedback, the main malfunctions are related to the decommissioning of the silicone gasket and the abrasion of the ceramic plates - the ceramic crane of the box is dripping.
Types of malfunctions
By mechanical scrolling of the rod and visual inspection it is possible to determine the presence of a defect.
Malfunctions of a crane of an axle box consider:
- abrasion and deformation of the silicone clamping washer in the saddle
- damage to the metal elements of the rotary stem
- worm gear wear.
remove mechanical abrasion of plates
The abrasion of the working surface of ceramic plates and the formation of small-structure furrows is a common defect.
The surface can be ground using a paste made of alumina powder mixed with machine oil or a grinder for auto.
The paste is applied to a piece of thick glass and grinds the surface to a uniform surface. The method of one-sided lapping of ceramics makes it possible to smoothly fix the crane with an axle.
determine the mechanical damage
It is more difficult to repair metal elements of worm gear and rotary stem. The flywheel of the worm gearbox with the ceramic plates is a rotary.
To understand that the crane of the box can be defective by characteristic features: water flows or drips with the valve closed, there is no fixation of the valve in extreme positions, the head of the jet is weakened, jerks and shocks occur when the head is turned on.
Abrasion and deformation during operation of the clamp of the clamping washer are considered a simple type of fault. Simple repairs of ceramic crane axle boxes can be made by hand.
Repair of the ceramic crane axle box with your own hands
Visual inspection of the gasket in the seat of the assembly helps determine the possibility of replacing it. Therefore, the tap is disassembled using a ring wrench at 17.
If the gasket has a coating on the surface, try to remove it by placing the gasket in a solution of warm water. Then determine the quality of the circular clamping bar on the rod, the thickness of which in working condition is 1 mm. If the clamping washer is deformed and thinned, it must be replaced.
How to make a simple repair of the axle crane, shown here.
The replacement of the damaged elements of the rotary stem and the wear of the worm gear are considered more difficult.
Damage to metal elements in the form of chips and cracks on the surface of ceramic plates, damage to the threaded part or complete wear of the body or rod parts assumes a complete replacement of the unit.
In practice, repairing individual parts is laborious, so preference is given to complete replacement, especially since the cost of a new axle crane allows this to be done. To change the ceramic faucet axle, it is necessary to purchase a new one according to the sizes and parameters of the corresponding faulty one.
Helpful Tips
To properly replace the assembly, it is necessary to distinguish the rod end in the form of 12 and 16 of the final sprocket. Landing hole ceramic box crane, the installation of which directly depends on the length and number of splines that provide the fastening flywheel, it is recommended for preliminary measurements.
Mixers of domestic production have the form of fastening under the valve square and the fixing screw. For ceramic faucet boxes use a thread M21x1.5 mm or M18x1 mm.
Metal spring elements are not recommended for internal fixing of the gasket. The head of the axle crane should ideally match the shape of the mixer flywheel. For a node with a splined head, it is necessary to purchase a similar flywheel.
The best option for the complete identification of the old worn out assembly is the seller's recommendation.
Replacement of the axle crane in the single-lever mixer by hand
The main stages of replacing the mixer assembly are:
Overlapping water and removing the valve.
Removing the flywheel and decorative sleeve, loosening the lock nut.
Unscrewing the axle crane and cleaning the thread of the saddle.
We are trying to find a new knot in the place of the body.
We check the operability of the installation.
Tightening the sealing nut.
Installation of the valve handle.
Water supply and check for leaks.
The replacement of the node on a two-ventilated mixer will help video.
