Tips for purchasing auto parts:

1. Check whether the trademark logo is complete. The outer packaging of authentic products is of good quality, with clear writing on the box and bright overprinting colors.

2. Check whether the geometric dimensions are deformed. Some parts are prone to deformation due to improper manufacturing, transportation, and storage. During inspection, you can roll the shaft part along the glass plate and see if there is light leakage at the joint between the part and the glass plate to determine whether it is bent.

3. Check whether the joint part is flat. During the transportation and storage of spare parts, due to vibration and bumps, burrs, indentations, damage or cracks often occur at the joint parts, which affects the use of the parts. Pay attention to inspection when purchasing.

4. Check whether there is any rust on the surface of the parts. The surface of qualified spare parts has both a certain degree of precision and a shiny finish. The more important the spare parts, the higher the precision, and the stricter the rust and corrosion prevention of the packaging. When purchasing, you should pay attention to inspection. If you find that the parts have rust spots, mildew spots, or the rubber parts are cracked or lose elasticity, or there are obvious turning tool lines on the journal surface, they should be replaced.

5. Check whether the protective surface is intact. Most parts are factory coated with a protective coating. For example, piston pins and bearing bushes are protected with paraffin; piston rings and cylinder liners are coated with anti-rust oil and wrapped in wrapping paper; valves, pistons, etc. are soaked in anti-rust oil and sealed in plastic bags. If the sealing sleeve is damaged, the wrapping paper is missing, and the anti-rust oil or paraffin is lost when purchasing, it should be returned or replaced.
