Navigating OEM vs. Aftermarket Construction Parts: A Contractor’s Guide
Today, road construction machinery spare parts are available as original parts, sub-parts, replacement parts, repair parts, used parts, and so on. A wide variety of spare parts can be found everywhere in the market. Choosing becomes the problem we face. What we have to understand is that almost no machinery manufacturer can build all the parts themselves. Even the most powerful manufacturers do not produce every screw themselves. Many of the thousands of parts on a milling machine are outsourced to specialized parts suppliers for production. Although some industry leaders have called for the standardization of the aftermarket and the establishment of an access mechanism, I have the impression that it is more of a sermon than a lecture. I think it is more important to guide customers on how to rationally view the difference between the original parts and replacement parts so that they have a basis for choice.
First and foremost, one of the most important bases of judgment is quality and reliability. Original parts are usually manufactured by original equipment manufacturers (OEMs) or their authorized suppliers, have the same quality standards and specifications as the original equipment, and carry the original brand label. They are rigorously tested and verified to ensure their performance and reliability. The quality and reliability of replacement parts, on the other hand, may vary depending on the manufacturer and supply chain. Some replacement parts are factory replicas made by disassembling the original parts. Some replacement parts are produced by authorized equipment suppliers after they have completed the production of the original parts required by the equipment manufacturer. These additional parts are also known as replacement parts, and the only difference between them and OEM parts is that they do not have the OEM label.
The second element of judgment is fit and compatibility. Genuine parts are manufactured to the design and specifications of the original equipment and are therefore usually more reliable in terms of fit and compatibility. Replacement parts may have some variations and may require additional adaptations or adjustments to ensure their full compatibility with a particular piece of equipment. However, as technology advances, the compatibility of many replacement parts for precision accessories is improving. For example, our Wirtgen String Sensor Wire Sensor is available in both original and replacement parts. Replacement parts come with a longer warranty and are half the price of original parts.
The third important element of judgment is warranty and support. Pure parts are usually matched with the manufacturer’s warranty and support policy. Purchasing pure parts entitles you to the warranty and after-sales support offered by the manufacturer. Warranty and support policies for sub-factory parts may vary from manufacturer to manufacturer and may require additional or even more paid warranty and support arrangements.
The fourth element of judgment is price and availability. OEM parts are usually cheaper than genuine parts because they don’t have to pay the OEM’s brand premium. The price of generic parts may be more competitive, but in some cases, a lower price may mean a compromise in quality and performance. In addition, genuine parts are usually more readily available because they are supplied by the manufacturer or its authorized dealers.
The fifth element of judgment is quality certification and standards compliance. Pure parts usually comply with relevant quality certifications and industry standards, which are required by the manufacturer. Quality certifications and compliance for sub-standard parts may vary depending on the manufacturer and supply chain. For critical equipment or applications that require long-term reliability, pure parts are often the more reliable choice.
However, in some cases, sub-factory parts may offer a more cost-effective solution, especially for older equipment or one-off repairs, for example. It is important to note that for some equipment and components, there may be multiple suppliers of substitutes, which may vary in quality and performance. It is also not true that all OEM parts are superior in quality to substitutes. Manufacturers are producing goods in accordance with the manufacturer’s requirements and do not represent the highest level of craftsmanship. In the case of one of our filter suppliers, 60% of the factory capacity is OEM for major manufacturers. However, this does not mean that the quality of the remaining 40% of the product is inferior to the OEM’s 60%.
When choosing replacement parts, you can get reliable quality, and inexpensive parts by choosing the right supplier. Since we are a road construction contractor ourselves, we have tried all kinds of original and replacement parts. After continuous trial and error, we know what parts can be selected as replacement parts and what parts must be selected as original parts.
