See if the joint is smooth. During the handling and storage of spare parts, due to vibration and bumping, burrs, indentations, damage or cracks often occur at the joint parts, which affect the use of parts. Pay attention to inspection when purchasing.

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

See if 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 wax; 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 packaged in plastic bags. If you find that the sealing sleeve is damaged, the wrapping paper is lost, the anti-rust oil or paraffin is lost when purchasing, you should return it.
