Repair and car operation

It is possible to "calculate" on characteristic signs. Buying in the market the second-hand car, especially by proxy, it is easy to catch the car with interrupted numbers. Recommendations of experts will help to be saved from such trouble.

Theory. If you decided to get a second-hand foreign car and chose concrete model, try to collect in advance about it information maximum. It is better to make all this, having examined similar model in salon which trades in new cars. First of all find out, where there should be identification number (VIN). At the car can be additional VIN овские stickers (are carried out as transfers), – learn, where they take place.

Practice. So, you start survey of the chosen car. It should be begun with check of a condition of a paint and varnish covering about identification numbers. It should not on color and the invoice to differ from a covering on inside of a luggage carrier, a cowl, a motor compartment. A soft surface (there is a deformation trace even from a nail), begin to flow paints and unevenness of its drawing – all this testifies that the place where there is identification number, was recoloured. And repaint hides either failure consequences, or traces of change of number. The covering near number can be rubbed a tampon moistened with solvent: if paint is dissolved at least partially, it is a sure sign of that it "not native".

Now it is direct about numbers and identification plates. If number is interrupted, there are characteristic signs of this operation: the metal surface is deformed, slightly convex or bent more often. At a handicraft way of thrashing the double contour is often appreciable; signs are not on one straight line, and "jump", at them various depth of cave-in; between letters or figures – intervals of different size. Special attention turn on identical signs. They should not differ from each other a form or in the sizes. One more important point: if on identical signs in numbers you noticed any characteristic – be sure that these signs not the factory. Firm number is put with a uniform stamp, "handicraftsman" for each figure or a letter uses a separate brand and repeats characteristic "mistake".

It is more difficult to reveal the "criminal" car when number is replaced together in a detail or that its part on which it is beaten out. As a rule, in this case number – factory. Therefore it is necessary to examine places of fastening of this detail to a body. Simple way of detection of such replacement there can be a prostukivaniye. You should guard, if a sound at a prostukivaniye deaf, "wooden" or jingling. It is necessary to remember that in cars separate parts of a body fasten a method of contact welding. Junctions usually represent points in diameter of 5-6 mm. If in places of fastening of a "number" detail to a body there are traces of other type of welding, and their surface also are deformed – means, the detail is fixed on a body not in the factory way.

At survey of the engine pay attention to a platform with number: it should be equal, and signs on it are beaten out accurately and brightly, without double contours. By the way, the platform is pierced on the milling machine from which there are traces in the form of polukruzhiya. They are well visible even at strong corrosion.

The described signs are rather simple for revealing even to the nonprofessional. There are also others, but they can be revealed only by experts. To them also it is necessary to address, if you still had doubts.
