Purchasing skills of automobile parts
First, look at whether the trademark logo is complete. Authentic packaging quality is good, the handwriting on the box is clear, and the overprinter color is bright. Carefully identify when buying to prevent buying fake and shoddy products.
Second, look at whether the geometric size is deformed. Due to improper manufacture, transportation and storage, some parts are easily deformed. The outer edge of frameless oil seal should be straight, deformed by hand, and restored to its original state after letting go. When buying all kinds of gaskets, we should also pay attention to check the geometric size and shape.
Third, see if the seam is flat. During the handling and storage of parts, burrs, indentations, damage or cracks often appear at the joints due to vibration and impact, which affects the use of parts.
Fourth, look for rust on the surface of parts. The more important the spare parts, the higher the precision, and the stricter the packaging rust prevention and corrosion protection. The surface of qualified parts has both certain precision and bright finish.
Five, see whether the protective surface is in good condition. Most parts are coated with protective layer when they leave the factory. For example, the piston pin and bearing bush are protected by paraffin; The surfaces of piston rings and cylinder liners are coated with antirust oil and wrapped with wrapping paper; Valves, pistons, etc. Soak in antirust oil, and then pack in plastic bags.
Six, see if there is any looseness in the glued parts. Parts are press-fitted, friction plates and steel sheets are riveted or glued; Filter paper is adhered to the filter element skeleton of the paper filter; The wire ends of electrical equipment are welded. choose
Seven, see whether the rotating parts are flexible. When buying rolling bearings, one hand supports the inner ring of the bearing and the other hand rotates the outer ring. The outer ring should be able to rotate quickly and freely, and then stop gradually. If the rotating part can't work normally, it means that the inside is corroded or deformed. Don't buy them.
Eight, look at the assembled parts. Conventional assembly parts must be intact.
