The intermediate surface

All laying vehicles used for sealing the interface mating surfaces of two or more items, and serve to prevent leakage of oils and fluids within the assembly and maintenance of high pressure or vacuum.

Often these pads before installing covered in liquid or paste sealing compound. Often under the influence of time, temperature or pressure occurs so strong "from sticking" to each other interfaced surfaces that division of details becomes difficult to achieve. In many cases, the dismantling of these assemblies helps tapping them outside the perimeter of the junction hammer with soft brisk. You can use for this purpose also the usual hammer, putting blows through a wooden or plastic spacer. Do not make tapping cast cases and fragile components. In the event of such difficulties always first check that all your hardware is removed.

Avoid applying to separate parts screwdriver or pry bar, introducing them between the mating surfaces, since the sealing surfaces at the same time can be easily damaged, which can later cause leaks. If podrychazhivaniya "become attached" elements of the assembly can not be avoided, use for this purpose the handle from old brooms, but bearing in mind that, after all the formed chips should be carefully removed from the mating surfaces and the inside of the assembly.

After the separation of parts of the mating surfaces should be thoroughly cleaned with a scraping traces of the old gasket material. The hardened fragments of the old gasket can be pre-softened with a converter rust or a special chemical composition and then removed from the mating surface of the scraper. As in this case a scraper may be used to cut the copper tube and flattened pointed end. The use for this purpose is a copper tube is recommended, as copper is usually softer materials used in the car, which reduces the risk of damage to the mating surfaces. Some pads can be easily removed with a copper brush, however, regardless of the method used, the mating surfaces must be absolutely clean and smooth. If for some reason turned out to scratch the mating surface, before assembling the components fill the scratch gasket sealant. In most cases, you should not use the curable (or poluzastyvayuschim) sealant.
