Here is some method to identify genuine and fake accessories:
1, with or without rust, mildew and aging: the auto parts store in, due to the quality of the material itself, save the environment, save the time, prone to dry, oxidation, discoloration, aging and other physical phenomena. If accessories above can not buy.
2, with or without Breakage burr. Whether the formation of combined plane, often shoddy products appearance finish lower, and there are cracks, sand holes, slag, burrs or bumps. Such as cylinder head gasket extrusion deformation, easy to use, cause Mifengbuyan ablation, resulting in spills, leaks, and leaks; burr easily pull cylinder piston and ring work surface; crank arm rounded at the crack after high-speed loading operation may appear broken machinery accident.
3, the presence or absence of bending and torsion deformation. For example, shaft parts and tire storage method is wrong, and prone to distortion, actual size to reach the requirements.
Without loose and catching phenomenon. Clutch plate rivets loose, brake hose unglued, electrical parts connectors off paper filter seams disengaged phenomena such can not be used. Optional generator, starter, distributor should rotate freely, otherwise, can not be installed.
5 mark, whether the assembly, assembly components are missing pieces. Assembly marks, such as the timing gear mark the piston at the top of the tag should be intact clear, it is an important basis to ensure that the parts properly installed relations, there is no assembly or mark unclear, it is definitely not an option. The assembly is complete and intact, in order to ensure smooth loading and the normal operation of a number of individual small parts assembly parts missing equipment will give loading cause difficulties, often due to a shortage of individual small accessories, the user is difficult to solve.
6, no protective layer on the surface of parts. In order to facilitate the safekeeping, to prevent the parts bump, parts factory, has a protective layer. Such as cylinder liner, the size of the bearing, piston, valve, etc. are generally protected with paraffin to prevent surface damage ring. Especially if there are no protective layer of some important accessories surface, "parallel".
7, whether the product manual, certificate, especially including the accessories and the name and registered trademark. Some important parts, and assembly, such as the carburetor, distributor, generators factory are generally of a manual, certificate, maintenance, and installation considerations used to guide the user, in the absence of these mostly fake and shoddy products.
Specification compliance requirements, the purchase of auto parts to identify the main technical parameters should be consistent with the use of special technical requirements specification While some accessories appearance is almost the same, but little attention is not installed on the train, or leave anthropogenic hidden faults.
