1. Check the Part Number
The part number is the first and most reliable indicator of authenticity. Both Caterpillar and Komatsu use unique and consistent numbering systems. A genuine part will always have a clearly engraved or printed part number directly on the product or on its OEM label.
Examples:
- Caterpillar: “6Y7197”, “8E5346” or “1R0749”.
- Komatsu: “708-2L-00510” or “207-27-51310”.
If the part only shows a generic label or cannot be found in the official manufacturer catalog, it’s a red flag for authenticity.
2. Verify Packaging and Labels
Original parts are always delivered in official Caterpillar or Komatsu packaging with registered logos and tracking information. Packaging is part of the manufacturer’s quality control process.
- Caterpillar: yellow and black boxes with the “CAT” logo and unique barcode.
- Komatsu: blue and white boxes with logo, lot number, and authenticity seal.
- OEM parts are never shipped in plain boxes or without identifiable lot codes.
Tip: keep the original packaging for warranty or future verification.
3. Request the OEM Reference or Invoice
A reliable supplier such as All Parts Machinery will issue a sales invoice or certificate including the OEM reference or manufacturer’s part number. Professional distributors clearly indicate whether the part is OEM, remanufactured, or aftermarket, along with its serial or batch information.
4. Inspect Engravings and Physical Finish
Authentic parts feature precise and clean manufacturing details. Part numbers or logos are permanently marked by laser or mold — not printed stickers.
- Surfaces are smooth, consistent, and free of burrs.
- Color and paint consistency remain uniform across series.
- Logos are properly aligned and use the correct typeface and colors.
If you notice rough finishes, blurry engravings, or incorrect logo designs, it’s most likely a non-OEM component.
5. Consult Official Catalogs or Trusted Suppliers
Before purchasing, verify the part number through the official Caterpillar or Komatsu online catalogs. If the number doesn’t appear or refers to a different model, it could be a reproduction.
At All Parts Machinery, our technical team can confirm part authenticity and compatibility in minutes using OEM data and manufacturer databases.
6. Be Cautious of Prices That Are Too Low
Price differences are normal, but when a product is far below market value, it’s often a counterfeit or low-quality replica. Avoid buying from sellers with no verifiable reputation or who cannot provide a written warranty.
Remember: a fake part can cause major mechanical failure, downtime, or costly damage to your equipment.
