Avoid the Aftermarket Gamble: Why Used OEM Parts Are a Safer Bet

Updated: Dec 7



When your excavator is sidelined by a faulty part, you face a tough decision: should you save on upfront costs with aftermarket parts, or should you opt for used OEM (Original Equipment Manufacturer) parts, which promise reliability? Many earthmoving professionals in South Africa are tempted by the lower prices of aftermarket components, but this can often be a costly gamble in the long run.

Let’s dive into why used OEM parts are the smarter choice and how Vikfin ensures your machines get back to work quickly and affordably.


1. Reliability: Built to Last, Not Just to Fit

Aftermarket Reality: Aftermarket parts are manufactured by third-party companies, often at a fraction of the cost of OEM parts. While the lower price tag is appealing, it comes at the expense of reliability. The materials used may not meet the rigorous standards of OEM components, leading to premature wear and tear. For example, a critical component like a final drive gear bought aftermarket might cost around R20,000 but could fail within six months, putting your entire project at risk.

OEM Advantage: OEM parts, even when used, are built to the exact specifications and quality standards of the original manufacturer. They are designed to handle the demands of heavy earthmoving, whether it’s lifting, digging, or moving tons of debris. A used OEM final drive from Vikfin might cost R30,000 but will last significantly longer, saving you money on frequent replacements and downtime.


2. Fit: The Perfect Match for Your Machine

Aftermarket Pitfalls: Poorly fitting parts are one of the biggest risks with aftermarket alternatives. A slightly off-center pin or a misaligned bolt hole can lead to operational inefficiencies, increased wear on neighboring components, and even safety hazards. Imagine paying R12,000 for an aftermarket bucket cylinder only to find it leaks because the seals don’t sit properly.

OEM Precision: Used OEM parts are guaranteed to fit your machine perfectly, as they’re designed to the exact specifications of the original equipment. At Vikfin, every used part is inspected for wear and tear to ensure it meets the highest quality standards. When you purchase a refurbished bucket cylinder for R18,000, you’re not just buying a part—you’re buying peace of mind.


3. Performance: Don’t Sacrifice Power for Price

Aftermarket Compromises: While aftermarket parts may seem to function adequately at first, they often don’t deliver the same level of performance. A cheaper aftermarket slew motor costing R25,000 might offer acceptable rotation speed initially, but it’s likely to degrade faster under the stress of continuous use.

OEM Superiority: Used OEM parts maintain the performance levels expected of the original equipment, ensuring that your excavator operates at peak efficiency. A refurbished OEM slew motor from Vikfin priced at R35,000 offers consistent power, reliable performance, and a longer lifespan.


4. Downtime Costs: The Hidden Price of Cheap Parts

Every hour your machine is out of action costs you money. If a poorly made aftermarket part fails, not only do you face replacement costs but also project delays and potential penalties.

For example:

  • Downtime Cost: R10,000/hour

  • Replacement Cost: R20,000 for the aftermarket part

  • Additional Labor: R5,000

Total cost of failure: R35,000 or more.

With a used OEM part from Vikfin, you pay slightly more upfront but avoid repeat failures and the snowballing costs of downtime.


5. Warranty: Confidence Backed by Guarantees

Aftermarket Uncertainty: Many aftermarket parts come with limited or no warranty. Even if warranties are offered, they often don’t cover labor costs or collateral damage caused by part failures.

Vikfin Assurance: All used OEM parts at Vikfin come with a warranty, ensuring you have recourse if something goes wrong. This reflects our confidence in the quality of the parts we supply. A warranty-backed hydraulic pump for R45,000 offers better security than a no-warranty aftermarket equivalent at R30,000.


6. Sustainability: A Greener Choice

Choosing used OEM parts isn’t just better for your budget—it’s better for the planet. By extending the life cycle of original components, you reduce waste and minimize the environmental impact of manufacturing new parts.

At Vikfin, we take pride in refurbishing OEM parts to near-new condition. By choosing a R15,000 used OEM exhaust instead of a new aftermarket one for R10,000, you’re making an environmentally responsible decision.


7. Expertise: Trust Matters

When you buy aftermarket parts, you’re often left to figure out compatibility and installation on your own. At Vikfin, our team of experts ensures you get the right part for your machine. Whether it’s a R40,000 dipper arm cylinder or a R50,000 swing bearing, we’ll guide you through the selection process and provide technical advice to keep your machine running smoothly.
