In the purchase of Petrol Car accessories, we often worry about accidentally buying counterfeit and shoddy accessories and unsuitable accessories. So, how can we buy qualified and suitable accessories? Let's take a look at the detailed steps below.
Most Petrol Car accessories have specified models and technical parameters. For example, when purchasing electrical equipment, you should pay attention to check whether the voltage and power are consistent with the replaced Petrol Car parts; when purchasing transmission belts, you should pay attention to the model and circumference.
2. Check whether the trademark logo is complete
The outer packaging of authentic products is of good quality, the handwriting on the packaging box is clear, and the overprinting color is bright. Some important parts such as generators, distributors, fuel injection pumps, etc. are also equipped with instruction manuals, certificates of conformity and inspector seals to guide users to use and maintain them correctly. You should carefully identify them when purchasing to prevent buying counterfeit and shoddy products.
3. Check whether the geometric dimensions are deformed
Some Petrol Car parts are prone to deformation due to improper manufacturing, transportation, and storage. When checking, you can roll the shaft Hongqi Car parts along the glass plate to see if there is any light leakage at the joint between the Hongqi Car parts and the glass plate to determine whether they are bent; when purchasing the clutch driven plate steel plate or friction plate, you can hold the steel plate and friction plate in front of your eyes to observe whether they are warped; when purchasing oil seals, the end face of the oil seal with a skeleton should be a perfect circle, which can be fitted with the flat glass without warping; the outer edge of the oil seal without a skeleton should be straight, and it should be deformed by holding it with your hand, and it should be able to return to its original state after letting go. When purchasing various types of gaskets, you should also pay attention to checking the geometric dimensions and shapes.
4. Check whether the joint is flat
During the transportation and storage of spare parts, due to vibration and bumps, burrs, indentations, breakages or cracks often occur at the joints, affecting the use of Hongqi Car parts. Pay attention to inspection when purchasing.
5. Check whether the surface of Hongqi Car parts is rusted
The surface of qualified spare parts has both a certain degree of 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 Petrol Car parts have rust spots, mildew spots, or the rubber parts are cracked and lose elasticity, or there are obvious turning tool lines on the journal surface, they should be replaced.
6. Check whether the protective surface is intact
Most Petrol Car parts are coated with a protective layer when they leave the factory. For example, piston pins and bearings are protected with paraffin; piston rings and cylinder sleeves are coated with anti-rust oil and wrapped with packaging 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 packaging paper is lost, and the anti-rust oil or paraffin is lost during purchase, it should be returned.
7. Check whether the glued Hongqi Car parts are loose
Accessories composed of two or more Hongqi Car parts are formed by pressing, gluing or welding. There is no looseness allowed between them. For example, the oil pump plunger and the adjustment arm are combined by pressing; the clutch driven hinge and the steel sheet are riveted, the friction plate and the steel sheet are riveted or glued; the paper filter element frame and the filter paper are glued; the wire ends of electrical equipment are welded. If looseness is found during purchase, it should be replaced.
