Auto parts purchasing skills:

First of all, 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.

Secondly, see if the geometric dimension is deformed. Due to improper manufacture, transportation and storage, some parts are easily deformed. When checking, you can roll the shaft parts around the glass plate to see if the joint between the parts and the glass plate leaks light, so as to judge whether they are bent.

Third, see if the joint 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. Pay attention to inspection when buying.

Fourth, look for rust on the surface of parts. The surface of qualified parts has both certain precision and bright finish. The more important the spare parts, the higher the precision, and the stricter the packaging rust prevention and corrosion protection. Pay attention to inspection when buying. If the parts are found to have rust spots, mildew spots or rubber parts are cracked and lose elasticity, or there are obvious turning lines on the surface of the journal, they should be replaced.

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. If it is found that the sealing sleeve is damaged, the wrapping paper is lost, and the antirust oil or paraffin wax is lost, it should be returned.
