Every contractor knows this pain: the site is running, the crew is on the clock, and then—bam—your excavator coughs up a final drive or blows a hydraulic pump. Suddenly, the entire job grinds to a halt.
And while your machine sits, your costs don’t. You’re paying workers, burning through fuel for idling equipment, and worst of all, you’re missing deadlines. One day of downtime can bleed tens of thousands of rand out of your pocket.
Now, most contractors call the dealer. They order a brand-new OEM part at a premium price, and then they wait—sometimes weeks—for the part to arrive. By the time it’s installed, you’ve lost more than money. You’ve lost time, client trust, and maybe the next contract.
But there’s a smarter way. A hidden goldmine most contractors don’t fully tap into: used OEM excavator parts. These parts don’t just save you a few bucks—they can literally save you millions in avoided downtime and unnecessary overhead.
This blog dives into why used OEM parts are the lifeline of smart contractors, how they stack up against new and aftermarket options, and how Vikfin has built its reputation by delivering this hidden goldmine to South Africa’s construction industry.
2. What Exactly Are Used OEM Parts? (And Why They’re Not Junk)
Before we get too deep, let’s clear up the lingo.
OEM (Original Equipment Manufacturer): These are the parts built by the same manufacturer who built your excavator. If you own a Komatsu, it’s a Komatsu part. If you own a Volvo, it’s Volvo. OEM means the part is made to exact design and quality standards, tested for heavy-duty performance.
Aftermarket parts: These are copycats. They’re built by third-party companies trying to replicate the OEM design. Some are decent. Many are garbage. And when you gamble on them, you’re gambling with your uptime.
Used OEM parts: These are genuine OEM parts that have already been used in another machine but still have plenty of life left. Think of it like buying a high-quality second-hand car instead of a cheap knockoff.
Here’s the big myth contractors get wrong: used doesn’t mean worn-out scrap. A Komatsu swing motor or a Volvo final drive might be pulled from a machine that was scrapped for reasons unrelated to the part. In the right hands, that component gets cleaned, tested, and put back into circulation—ready to run for thousands more hours.
That’s the goldmine. Same OEM quality, but at a fraction of the cost.
3. The Economics of Excavator Ownership
Let’s break it down. Owning and operating an excavator is not just about the sticker price of the machine. Here’s where the money goes:
Purchase price: Millions of rand upfront.
Fuel costs: One of the biggest ongoing expenses.
Labor: Operators, mechanics, site supervisors.
Maintenance and parts: Everything from filters to final drives.
Downtime: The silent killer.
Here’s a reality check: parts and maintenance can chew up 20–30% of the total cost of ownership over an excavator’s life. That’s massive.
Now imagine you’ve got a Caterpillar 320 and the final drive fails.
New OEM final drive: R350,000+
Aftermarket knockoff: R180,000 (but good luck with fitment and reliability).
Used OEM final drive: R120,000–R150,000.
That’s a 50–60% saving right there—without sacrificing OEM quality. Multiply that across a fleet of machines, and you start to see how contractors can literally save millions over a few years.
4. Why Contractors Bleed Money on New Parts
So why do so many contractors still throw cash at new OEM parts? A few reasons:
Fear of risk. They think used means unreliable. But the truth is, a properly sourced used OEM part is every bit as trustworthy as new.
Dealer dependence. Many contractors are conditioned to “just call the dealer” when something breaks. Dealers love this—because they make a killing off your loyalty.
Lack of awareness. Not everyone knows there’s a thriving used OEM market that delivers the same quality at half the cost.
The problem with new OEM parts isn’t just the price tag. It’s the waiting time. Dealers don’t always have the part in stock. Imports can take weeks. Meanwhile, your machine sits like a deadweight. That delay costs you far more than the part itself.
5. The Reliability Myth: Used vs Aftermarket vs New
Let’s kill the reliability debate once and for all.
New OEM parts: Yes, they’re reliable. But they come at a premium, and supply chains aren’t always fast.
Aftermarket parts: A mixed bag. Some work okay. Many don’t. You risk poor fitment, early failures, and voided warranties. Saving money upfront often costs more long-term.
Used OEM parts: The sweet spot. Built to the exact standards your excavator needs. Proven to handle harsh duty cycles. Tested and cleaned by reputable suppliers.
If you had to bet your business on one option, used OEM wins for most scenarios. It balances cost, availability, and dependability.
6. Real-World Savings: Case Studies from the Field
Here’s where the numbers speak.
Case 1: Final Drive ReplacementA Gauteng contractor needed a Volvo EC290 final drive. Dealer quote: R360,000 with a 3-week wait. Vikfin supplied a tested used OEM final drive for R140,000 within 48 hours. Job kept moving. Net savings: R220,000 plus three weeks of productivity.
Case 2: Hydraulic Pump FailureA KwaZulu-Natal fleet manager faced downtime on a Komatsu PC200. New OEM pump: R280,000. Used OEM pump: R120,000. Machine was back on-site in 2 days. Savings: R160,000 and zero project delays.
These aren’t hypothetical. They’re real-world contractor wins. Multiply that across a fleet, and the “hidden goldmine” becomes obvious.
7. The Downtime Killer: Why Speed Matters More Than Price
Let’s be clear: downtime costs more than parts.
Every day your excavator sits broken, you’re losing:
Operator wages.
Penalty clauses for missed deadlines.
Opportunity cost of not finishing jobs on time.
A single idle day can cost R50,000–R100,000.
That’s why speed matters more than price. You could pay 30% more for a part if it gets you running today instead of next week. But with used OEM parts, you don’t have to choose—you get both: speed and savings.
8. The Environmental Goldmine: Why Used Parts = Sustainability
Construction isn’t exactly an eco-friendly industry. Excavators guzzle diesel, chew up landscapes, and churn out carbon. But there’s one way contractors can make a dent: reuse.
Buying used OEM parts keeps thousands of tons of steel, aluminum, and rubber out of landfills. It reduces the carbon footprint of manufacturing new components. And it plugs into the circular economy—where parts get multiple lifecycles before being scrapped.
Even better? Contractors can market their projects as eco-conscious by sourcing reused parts. That’s becoming a selling point with developers, investors, and government projects pushing green credentials.
9. How to Spot a Quality Used OEM Part (Contractor’s Checklist)
Not all used parts are created equal. Here’s a contractor’s checklist before buying:
Supplier reputation. Buy from trusted names like Vikfin, not some backdoor scrapyard.
Inspection process. Was the part cleaned, tested, and verified? Or just pulled out and resold?
Warranty. Even a short-term warranty proves the supplier stands behind their product.
Hours of use. Parts from low-hour machines are obviously more valuable.
Documentation. Reliable suppliers can tell you where the part came from.
If your supplier ticks those boxes, you’re in safe hands.
10. The Vikfin Difference: Turning Scrap Into Value
Here’s where Vikfin stands apart.
Transparent sourcing: Every part comes from carefully dismantled excavators.
Rigorous inspection: Components are cleaned, pressure-tested, and verified before sale.
Fast availability: Stock is kept locally in South Africa. That means days, not weeks, of waiting.
Contractor focus: Vikfin doesn’t just sell parts—we keep contractors moving, profitable, and stress-free.
That’s the goldmine. Taking what looks like “scrap” and turning it into value for the people who actually keep South Africa building.
11. Future Outlook: The Growing Role of Used OEM in Construction
The world is changing.
New OEM parts are only getting more expensive.
Shipping delays are becoming the norm.
Contractors are under more pressure than ever to cut costs and meet deadlines.
The result? A massive shift toward used OEM parts as the new normal. What was once seen as “second-hand” is now seen as smart business. The contractors who adapt early will save the most. Those who don’t will keep bleeding profits to dealers.
12. Conclusion: The Smart Contractor’s Goldmine
Every excavator part tells a story. Some are brand-new, expensive, and slow to arrive. Others are cheap knockoffs that fail when you need them most. But then there are the hidden gems—used OEM parts that combine reliability, affordability, and availability.
That’s the contractor’s goldmine.
Save millions over a fleet’s lifetime.
Slash downtime from weeks to days.
Build a greener, more sustainable business.
At Vikfin, that’s what we deliver every day. Because the truth is simple: in construction, the contractor who controls downtime controls profit. And used OEM parts are the secret weapon to do exactly that.
Stop bleeding money. Start digging into the goldmine. Choose used OEM with Vikfin.
