Sharoks for repair Sadls of valves - how to perform work without problems?

Bashes for repair Sadls Valves are need when working with this mechanism, because more convenient and accurate instruments are not found. The only alternative can serve the Zenkovka. We will talk about all this and about the repair process.

The valve mechanism device is the principle of operation and possible malfunctions

Valves are used to seal the engine cylinders in the gas exchange process. The principle of their work is to ensure the inlet of a mixture of fuel and air for its further compression. After ignition and testing, the gases fall into the release system, valves also correspond to this. This mechanism functions in aggressive conditions, is constantly subjected to high dynamic loads, high speed and heat speeds. To reduce rapid wear of the driving parts of this part, manufacturing materials most often have a high degree of doping with nickel and chrome.

The valve mechanism device has two main components: it is head and rod. These nodes of the car are with a tulip, flat and convex head. At the end of the rod there are cone, shaped or cylindrical grooves for fixing springs on them. The main manifestation of the malfunction of the valve mechanism is, as well as the unstable operation of the motor as a whole. Faults of this type occur due to sticking and appearance of the gap. Nagar can also cause this problem, it accumulates at the valve itself and prevents its closure.

Another sign of a malfunction is an increased emissions of smoke during the exhaust. A worn rod and the cause of unnatural engine noise.

Zenkalkovka and balls for repair Sadls of valves - what to choose?

The replacement of the valve saddle with their own hands provides for the presence of not only a coarse tool, but also almost jewelry - shag or zenker. These highly specialized tools are used only for repairing an internal combustion engine. A set of shag for valve saddles is used to pull the desired form of their internal diameter.. This operation allows you to achieve a tight closure from a plate. To unmistakably process the valve seat, the mechanism drawing is desirable to have at hand.

The shag is made in the form of a metal cylinder, in which there is a hole and two or one conical surface, its angle may vary from 15 to 60 degrees. There are cutters on the cone surface. A set of cenks for repairing the valve saddle is used in the same way as the shag, but there is one difference. Zenker can be used on mechanical and electrical instruments.

Replacement of valve saddles with their own hands - disassemble the specifics of work

Such an operation is performed in two ways. The first is rough, but the easiest and fastest. It is carried out quite primitively: an old valve is welded on a worn ring of the saddle, and then the ring is simply knocked out with a hammer from his regular place in the head of the cylinder head, it can be damaged, which is very undesirable. Then the process of pressing a new one occurs. The soft way is much more complicated, however, it will be performed in your garage without the intervention of expensive equipment. The saddle in this method is neatly pulled out on the machine. After that, the landing place is cleaned and also is calculated.

Reliable pressing occurs when the new saddle is cooled and heating the head of the cylinder block, only after such a work it will be guaranteed to reliably use the mechanism. All the difficulty of the method is heating and cooling, you will first need to think about how you will do it.. If the saddle is not worn away, it can be corrected. When using the repairs for repair, several mills with different angles are used. The first rude nozzle is put on the mandrel, after which the seedlings or clutch are prepared by circular movements, and the cenks for climbing valve saddle can be used in the same way.

Next, proceed to the wipe, it is carried out using a special device intended for this, at the end of which there is a cone. An abrasive powder or pasta is applied to the saddled chamfer. The trigger is carried out until the friction will make the minimum sound and grinds. The remains of the paste or powder are carefully cleaned. The quality of work can be evaluated by turning the head and bay in her kerosene, if it does not succeed, it means that we worked on the glory.
