How to Spot Counterfeit Excavator Parts (And Why OEM Used Beats Fake Any Day)

Counterfeit excavator parts are becoming a global plague — and South Africa is no exception. They look like OEM. They’re packaged like OEM. Some are even stamped like OEM. But inside? They’re time bombs. Cheap metals, sloppy tolerances, low-grade seals, and zero quality control.

The worst part?Contractors buy them thinking they’re getting a “good deal.”Then their machine detonates three jobs later — and suddenly that “cheap” part becomes the most expensive decision they’ve made all year.

This blog exposes how to identify fake excavator parts, how they sneak into the industry, and why OEM used parts from Vikfin are the safest, most cost-effective alternative.

Let’s get into it.

1. The Counterfeit Problem: Bigger Than Most Contractors Realise

Every excavator owner knows the feeling:

You need a part yesterday.The dealer price shocks your bloodstream.Then someone whispers,“Braa, I can get you the same part for half the price.”

And that’s how counterfeit parts travel:

• WhatsApp groups

• Telegram channels

• roadside suppliers

• uncertified workshops

• dodgy “importers”

They move quietly, quickly, and cheaply — and they destroy machines with the same speed.

Counterfeits cause:

• fried ECUs

• exploding pumps

• faulty sensors

• cracked gear housings

• early wear on entire systems

• safety hazards

• machine shutdowns

And worst of all?Manufacturers won’t honour warranty if a fake part played even a small role.

2. Why Counterfeit Parts Are So Dangerous

Counterfeiters don’t care about metallurgy, tolerances, durability, or safety. Their business model is simple:

“Make it look right. Make it cheap. Make money before the customer realises it's trash.”

Here’s the truth:

Fake parts fail between 2× and 20× faster than OEM.

They use:

• low-grade steel

• incorrect heat treatment

• poor casting techniques

• weak seals

• inaccurate machining

• zero factory testing

A counterfeit hydraulic pump, for example, can contaminate an entire system with metal shavings, destroying:

• travel motors

• swing motor

• cylinders

• control valve

A R12,000 “deal” becomes a R250,000 rebuild.

3. How to Spot Counterfeit Excavator Parts (The Real-World Contractor Guide)

You don’t need a lab.You don’t need a microscope.You just need to know the signs.

Here are the big red flags:

1. The Price Is Too Good to Be True

If OEM is R65,000 and someone offers the “same part” for R18,000, run.If the price feels like a miracle — it’s a trap.

2. Incorrect Weight

Fakes are often lighter due to inferior metals.10–15% weight difference = 100% fake.

If you pick it up and it feels “off,” trust your instincts.

3. Sloppy Casting and Machining

OEM parts are smooth, precise, and consistent.Counterfeit parts often show:

• rough casting

• uneven edges

• visible grinding marks

• mismatched threads

• misaligned bolt holes

If it looks ugly, it is ugly.

4. Incorrect Logos or Stampings

Counterfeiters try to recreate OEM markings, but they mess up:

• spacing

• font

• depth

• alignment

• serial formats

If the logo looks “slightly different,” it’s wrong.

5. Poor Packaging

OEM packaging is:

• clean

• consistent

• branded

• labelled with barcodes

• sealed

Fakes come in:

• generic brown boxes

• incorrect colours

• plastic wrap with no branding

• poorly printed labels

If the packaging screams “cheap,” don’t trust the item inside.

6. Missing Serial Numbers

OEM parts always have traceable numbers.If the part has:

• scratched-off numbers

• incomplete numbers

• stickers instead of engravings

…it’s 99% likely fake.

7. No Documentation

Counterfeits never include:

• quality control sheets

• manufacturing documents

• traceability certificates

OEM parts do.

8. Seller Can’t Tell You the Source

When the seller gives answers like:

• “We import from overseas.”

• “Same as OEM, just cheaper.”

• “Don’t worry, we’ve used them for years.”

That’s your sign to run.

4. The Real Reason OEM Used Parts Are Safer Than Aftermarket and Counterfeit

OEM used is not “second-hand junk.”It’s pre-owned engineering excellence.

Especially from a supplier like Vikfin, where parts come from:

• fleet retirements

• accident-damaged machines

• parted-out excavators

• machines with low working hours

Here’s why smart contractors choose OEM used:

1. OEM Quality at a Fraction of the Cost

You’re getting the same metallurgy, design, tolerances, and lifespan as new parts — but paying 40–70% less.

2. Zero Guesswork

OEM used parts fit perfectly because:

• same shape

• same size

• same bolt pattern

• same hydraulic ports

• same electrical connectors

No modifications.No grinding.No swearing.

3. Every Part Is Tested Before Sale

At Vikfin, we don’t sell parts based on looks.We test them like we’re trying to break them:

• pressure testing

• flow testing

• load testing

• leak tests

• noise checks

• solenoid response

• internal tolerance checks

If it fails even one metric, it goes to scrap — not customers.

4. OEM Parts Last Longer

An OEM used pump will almost always outlast a brand-new counterfeit pump.

Same with:

• travel motors

• cylinders

• ECUs

• alternators

• injectors

• starters

• sensors

• control valves

Because quality is baked into OEM components.

5. OEM Used Parts Protect Your Machine’s Value

Aftermarket and counterfeit parts lower resale value.OEM parts — even used ones — maintain it.

5. The Smartest Way to Avoid Counterfeit Parts Forever

You don’t need to play detective.You don’t need to gamble on random suppliers.You don’t need to guess whether something is OEM or fake.

You just need a trusted supplier who:

• knows excavators

• knows brands

• knows serial formats

• knows real OEM markings

• knows testing standards

• knows the difference between genuine and garbage

That’s what Vikfin does every day.

We source, inspect, test, verify, certify, and supply only real OEM used parts for:

• Volvo

• CAT

• Komatsu

• Doosan

• Hyundai

• Hitachi

• Kobelco

• Case

When you buy from Vikfin, you’re not buying a part.You’re buying certainty.

Conclusion: Counterfeits Kill. OEM Used Saves. Choose Wisely.

Fake parts will:

• kill your machine

• kill your budget

• kill your productivity

OEM used parts will:

• fit correctly

• last longer

• perform better

• protect your equipment

• save you serious money

In this industry, you don’t get points for being “cheap.”You get points for being smart.

And smart contractors use OEM.
