The indicator of the well-being of any apartment can be confidently considered flowing or not flowing cranes. If the kitchen or bathroom faucet clearly performs its functions and reliably discharges water, then you are damn lucky with a cocked axle. What is this - the crane of the box and why all plumbers insinuatingly and with reverence mention this name? And maybe not so scary, and you can make a replacement yourself?

What is a crane-box
The crane - box is a shut-off and regulating element, widely used in household plumbing fixtures (cranes and mixers).
Who though at one time was engaged in repair of cranes in kitchen or in a bathroom could personally see a cock-axle at work. Determine almost what type of crane-bush is in the mixer, you can practically in terms of the number of revolutions of the crane handle. In traditional worm cranes, it is necessary to turn the handle one and a half or two turns so that water appears. The maximum angle of rotation of the stem of the ceramic axle crane is a half-turn.
Any two-hand mixer in your apartment is equipped with this cold and hot water supply and closing device. The complete opening and closing working cycle is carried out by turning the handle with 20 splines to 180 degrees. The spline joint between the handle and the crane-axle is carried out by means of a gasket. Traditional crane worm gearboxes are equipped with rubber gaskets. A feature of the ceramic crane is the material from which they are made.
The ceramic locking element is made of cermet, which allows using the crane without additional elastic seals. The properties of the aluminum oxide of the closure element in due course provide a high surface purity.
Types of crane boxes
The axleboxes installed in mixers are of the following types:
• worm cuffs with rubber cuffs
• with ceramic inserts.
The principle of functioning of the worm axle crane is that the rubber gasket, pressing against the saddle of the crane, blocks the way to water. The water supply is regulated by 2-3 turns of the flywheel or crane handles. It is not difficult to guess that the main "weak link" of the worm gearbox system is the rapidly deteriorating rubber gasket.
The main element that performs the opening and closing of the water supply in the faucet with ceramic inserts is ceramic plates equipped with holes. The plates are equipped with symmetrical holes of a single configuration. One ceramic plate is fixed in the case of the axle box, the second on the flywheel rod.
The operating principle of a faucet with a ceramic beech is to rotate and then shift or align the existing holes in the plates. Thus, when the handle is rotated, access to the water supply to the mixer is provided.
Conditionally ceramic faucet axle can be presented as a removable cartridge. There are the following models of ceramic crane boxes:
• with a 12-point sprocket head
• for more modern models with a head in the form of a 16 final sprocket.
The landing place in the flywheel crane for the flywheel has a rod square section with a fixing screw. Therefore, for the crane of the axlebox, the ceramic square is distinguished by the height of the landing of the handle and the size of the seat, the selection of which is made according to the pattern of replacement.
The crane of the axlebox is also characterized by the length and number of splines intended for fastening the flywheel. The main number of splines are: 15, 20 and 24. There are also the size of the landing thread of the axle crane: the most running 1/2 "or 3/8".
How the ceramic crane is arranged
The main components of the axle crane are:
• housing
• rotary stem
• washer fixing
• Adapter
• ceramic plates (upper and lower)
• rubber sealing gasket
The body of the axle crane is the main fastening link, screwed into the mixer or the tap. Structurally, in the lower part of the valve body there are holes for water discharge.
The swivel stem is designed to attach the crane handle (flywheel). The swivel stem in the upper part of the element has a fixing screw, in the middle part an expansion ring, which fixes the rod. For coupling with the upper ceramic plate, an adapter is located at the bottom of the rod.
Carry out installation of the crane of the axle shaft of the rotary shaft into the housing and fix the rod allowing the washer to lock.
The rigid connection of the swivel stem with the top ceramic plate allows an adapter. Depending on the type of model, the shape of the adapter can be different.
Ceramic plates upper and lower perform free rotation of the rod.
Rubber gasket gasket provides an abutment of the crane of the axle box to the saddle of the mixer. Before assembling and installing the axle crane, it is recommended to carry out a preventive inspection of the condition of the crane seat.

How to replace the axle box with your own hands
To begin with, it is necessary to remember that the device of the crane of the axle box is varied. For domestic mixers, the shape of the flywheel is square and the fixing screw. For imported production models, this is the length and the characteristic number of slots under the handle, as well as the diameter of the threaded element.
Know that the most affordable for purchase are axleboxes with a half-inch thread. So do not forget to show your turned-over cocked axle to a pretty saleswoman from a sanitary supermarket. And now safely go home, and start to replace the purchased valve with axle box ceramic vidima.
Using a combination of pliers, remove the upper cap from the flywheel. Turning the bolt under the flywheel cap will allow the valve to be removed. After removing the tap valve, clean the fixing bolt from the debris. Then unscrew the faucet hardware, which will provide direct access to the box. Now unscrew the axle box and clean the mixer threads. Try on the new crane axle box.
If the model is correctly matched with ceramic inserts, the installation of the axle crane in the reverse order will be carried out quickly. When fixing the fixing of the ceramic case, it is necessary to control the degree of tightening with the help of a lock nut.
