Regardless of how you look after your machine, at some point parts will need to be replaced and you will be faced with the question: OEM or aftermarket. We have seen an increase in aftermarket parts out of China at very competitive prices. Local aftermarket parts availability has also been on the rise. So what is best for you? On the surface, OEM and aftermarket parts both do the same job, but each offers distinct advantages that set them apart.
OEM Parts
Equipment manufacturers will either subcontract parts production for their new lines of equipment or produce them in-house. Either way, these parts mostly cater to later model machines which means if you are running a later model machine, it could be challenging to find parts. The great advantage of OEM parts is that they provide the most precise fit. The downside is that the price tag on the OEM can be steep. I have come across cases where the OEM can be up to five times more expensive. An example is a cab on a 20-ton Komatsu excavator. The OEM part was R500,000 (approx. $30K) while the aftermarket was R85,000 (approx. $5k). If you can find the OEM parts you need and they fit into your budget, buying OEM components may be your best investment.
Aftermarket Parts
Aftermarket parts are produced by other manufacturers in the marketplace. With these parts, producers outside the original development team have the advantage of seeing what works best with the original design. They can use this research to eliminate flaws and make improvements, ensuring that most aftermarket parts provide you with similar performance to the OEM alternative provided you find a reputable and reliable seller that can stand behind the product.
Since there is more competition with aftermarket parts, they also tend to be the affordable option. Reduced parts costs can help you ensure you’re able to dedicate the resources necessary for maintenance and repairs when necessary. There are also more available options to select from, so it can be easier to find what you need fast and get it delivered.
How to Choose Between OEM Parts vs. Aftermarket Parts
Even with a grasp of the difference between OEM and aftermarket parts, it can still be tough to decide. Whether you’re performing a simple service or getting ready for a complete engine overhaul, see which option delivers the most benefits for you.
Take into consideration your:
Equipment age: There are more OEM options available for newer equipment. OEM producers are under no obligation to keep supporting older models. Options reduce each year your fleet grows older.
Operating budget: Performing maintenance on schedule, and repairs when necessary, is essential to keep your equipment in peak condition. To keep up, choose the option that best fits your budget. You can also look at second-hand/refurbished OEM parts.
Part accessibility: For some heavy equipment and in some locations, it can be tough to get dealer support. Aftermarket parts are more readily available. You can find them in equipment service shops and online.
Performance expectations: While OEM and aftermarket parts often have similar report cards, there can be differences that impact your bottom line. Compare when purchasing to see which delivers the maximum value.
