To identify the authenticity of automobile drive system parts, it is necessary to make a comprehensive judgment based on appearance, craftsmanship, markings, functionality, and purchasing channels.
Check Packaging and Labels
Genuine products have clear printing, bright colors, and complete markings (product name, model, manufacturer, address, anti-counterfeit code, etc.);
Important components come with a certificate of conformity, user manual, and inspector's stamp;
Counterfeit products often have rough packaging, vague or missing information, and usually no Chinese instructions (for imported parts).
Verify Anti-Counterfeit and Traceability
Scan the QR code on the packaging or scratch off the anti-counterfeit coating and verify through the manufacturer's official channels;
Prefer parts with traceable sources and avoid products with unknown origins.
Examine Appearance and Workmanship
Genuine parts have a smooth, flat surface without burrs, rust, bubbles, or cracks; metal parts have uniform plating, and rubber parts have good elasticity;
Counterfeit parts often have tool marks, poor soldering, delamination, or rubber cracking.
Measure Key Dimensions and Fit
Use calipers and other tools to measure key dimensions of shafts, bearings, etc., with deviations within ±0.05mm;
Rotating parts (like oil pumps, bearings) should rotate smoothly without sticking; assembled parts (like clutch driven discs) should fit without looseness.
Compare Prices and Channels
Be highly cautious of parts priced significantly below the market price (such as dozens of times cheaper).
