Let’s be blunt—the market is flooded with fakes. From Johannesburg to Durban, Cape Town to Rustenburg, contractors and plant hire businesses are being sold “genuine” parts that are anything but.
At best, these knockoff excavator parts underperform.At worst? They fail catastrophically and damage your machine—leaving you with massive downtime, a blown budget, and a very angry client on the phone.
So how do you protect yourself?
In this blog, we break down exactly how to tell the difference between genuine OEM parts and cheap knockoffs. We’ll show you what to look for, what to avoid, and how a trusted supplier like Vikfin can keep you from being duped—and keep your excavator working as hard as you do.
The Knockoff Problem: Bigger Than You Think
Knockoff parts come in many disguises:
Rebranded as OEM with fake labels
Aftermarket parts passed off as “just as good as original”
Counterfeits imported in bulk from factories with zero quality control
And the consequences? Brutal.
Misaligned gear ratios that grind down your final drive
Substandard chrome rods that tear through seals in weeks
Brittle castings that crack under load
Cheap valves that leak or fail under pressure
South Africa has become a dumping ground for these inferior parts—and too many operators are paying the price.
Why Knockoffs Are So Dangerous
Here’s what makes them a real threat to your business:
❌ They’re Not Built to Spec
OEM parts are engineered to match the precise tolerances, loads, and fluid pressures of your excavator. Knockoffs? Not even close.
❌ They Fit Poorly
Mounting holes are often misaligned, threads don’t match, and fittings require modification—if they fit at all.
❌ They Don’t Last
Most fail long before the expected service life—costing you double in replacement and downtime.
❌ They Void Your Warranties
Fitting a counterfeit part can void warranties on your machine—or worse, cause chain-reaction failures.
How to Spot a Knockoff: A Buyer’s Checklist
Here’s a straight-talking guide to sniffing out fakes before they find their way into your excavator.
🔍 1. The Price Is Suspiciously Low
If the price looks too good to be true—it probably is.
Let’s say:
New OEM final drive: R150,000
Knockoff final drive: R35,000
Used OEM final drive from Vikfin: R60,000–R70,000, tested and guaranteed
The knockoff is cheap for a reason. It’s made with inferior materials, rushed through production, and likely to fail early.
✅ Pro tip: Ask for pricing across OEM new, used OEM (from Vikfin), and aftermarket. Compare wisely.
🔍 2. No Branding or Poor Packaging
OEM parts come in branded packaging—with:
Logo
Part number
Barcode
Holograms or tamper-proof seals
Knockoffs often show:
Generic white or brown boxes
Misspelled brand names (“KOMATSI”, anyone?)
Poor-quality print
No part numbers or identifiers
✅ Pro tip: If it looks like it was printed on a home inkjet, walk away.
🔍 3. Incorrect or Inconsistent Part Numbers
OEM part numbers follow strict formats. Knockoffs often:
Invent part numbers
Use outdated or mismatched numbers
Avoid part numbers altogether
✅ Pro tip: Always verify the part number against your machine’s manual—or just call Vikfin. We’ll confirm it for you.
🔍 4. Material Quality Feels Wrong
A trained hand can tell instantly:
Cheap castings feel rough and brittle
Subpar chrome rods look dull or feel sticky
Seals feel dry, cracked, or rubbery (not pliable)
Flanges are uneven or lack finishing
✅ Pro tip: Compare the weight of the part. Knockoffs are often lighter due to inferior metals.
🔍 5. No Performance Guarantee
Ask the seller:
“Has this part been pressure tested?”
“Is there a return policy?”
“What happens if it fails in two weeks?”
If they hesitate, make excuses, or offer no paperwork—you’re not buying from a trusted source.
✅ Pro tip: At Vikfin, we pressure-test all hydraulic components and run compression tests on engines. If we wouldn’t use it ourselves, we won’t sell it.
🔍 6. The Supplier Is Shady
Fly-by-night suppliers are everywhere. Warning signs include:
No physical address
Only a mobile number, no landline
Cash-only deals
No business registration
Pushy sales tactics
✅ Pro tip: Buy from a supplier with a yard, workshop, and reputation—like Vikfin. Come visit. Meet the team. See the parts.

Real Story: A Knockoff Nightmare
A Gauteng-based plant hire business bought a cheap boom cylinder off a Facebook seller.
The part arrived late, with no documentation.
Mounting holes didn’t line up.
It leaked on install.
The supplier ghosted them.
They called Vikfin. Within 24 hours, we delivered a tested, refurbished OEM Komatsu cylinder. It bolted straight on and is still running strong today—six months and counting.
