The Dark Side of Cheap Aftermarket Excavator Parts (And How to Spot the Good Stuff)

Let’s cut the crap.

You’re in the middle of a job. Deadlines are tighter than a bull’s backside in fly season. Your excavator’s final drive throws a tantrum, and now your operator is chain-smoking behind the machine. You call around, looking for a replacement part, and some oke offers you a “brand-new aftermarket unit” for half the price of OEM.

Sounds like a steal, right?

Well, it might be. Or it might be the start of a mechanical horror story that ends in fire, hydraulic oil, and very loud swearing.

Welcome to the dark side of cheap aftermarket excavator parts—where things look shiny, feel promising, and fall apart faster than Eskom’s promises.

This isn’t a sermon. It’s a no-bull guide to:

• Spotting dodgy aftermarket parts,

• Understanding the risks of going “cheap and cheerful,”

• And most importantly—how Vikfin ensures the stuff we sell won’t screw you over.

Let’s Get Real: What Are Aftermarket Parts?

Not all aftermarket parts are evil. In fact, some are brilliant. Aftermarket simply means “not made by the original equipment manufacturer” (OEM). These parts can come from:

• Reputable independent manufacturers (quality stuff)

• Licensed suppliers (OEM spec or better)

• Random dodgy back-alley factories with no name, no shame, and zero accountability

So aftermarket isn’t the issue. Crap aftermarket is.

What Happens When You Buy the Wrong Part?

Let’s say you saved a few grand on a hydraulic pump that “looked just like the original.” A week later…

• Your boom jerks like it’s having a seizure,

• The seals start leaking like a drunk uncle at a funeral,

• And the pump lets out a noise that sounds suspiciously like “I told you so.”

Cheap parts = expensive problems. Here's what you're risking:

1. Catastrophic Component Failure

A fake final drive or swing motor can shred your undercarriage faster than you can say “warranty void.” One bad bearing in a cheap part = metal shavings in your entire hydraulic system. Game over.

2. Downtime That Bleeds Money

Each hour your machine’s offline, you’re haemorrhaging cash. Deadlines slip. Clients get twitchy. Operators sit around doing nothing but burning your diesel for aircon.

3. Safety Risks

Let’s not sugarcoat it—dodgy parts can kill people. A weak boom pin. A defective slew ring. A brake valve that fails under load. If that machine goes rogue, your crew’s at risk.

4. Hidden Costs

That “bargain” part? You end up paying:

• Double labour (removal, re-install, re-removal)

• Extra parts damaged by the bad one

• Possible legal liability if something goes south

Red Flags: How to Spot a Dodgy Part Before It Wrecks Your Machine

You don’t have to be a mechanical wizard to tell the difference between trash and treasure. Here are some signs that you’re looking at a Frankenstein-grade component:

1. It’s Too Cheap

If the OEM costs R20,000 and someone offers you one for R3,000—run. Good aftermarket parts might save you 20–40%, not 80%. Unless they found it under a bridge next to a troll, something’s wrong.

2. It Comes in Generic or No Packaging

Legit manufacturers don’t ship million-rand components in sandwich bags. If the box looks like it came from a roadside biltong stall, think twice.

3. No Branding or “Mystery Brands”

If the part has no markings or the logo looks like someone copied it from Google Images, it’s probably counterfeit.

Names like “Komassu” or “Hytatchi” are not clever branding. They’re red flags.

4. No Paper Trail

If there’s no invoice, no warranty, and the supplier avoids questions like “Where’s this from?”—you’re being hustled.

5. Looks Shiny, Feels Wrong

A freshly painted part can hide cracks, welds, or recycled components. Check:

• Welds (should be clean and uniform)

• Casting quality (no rough or inconsistent texture)

• Weight (dodgy parts are often too light or too heavy)

If it smells like petrol and desperation, trust your gut.

Common Parts Most Affected by Cheap Knock-Offs

Not all parts are equally risky. Here’s where you need to be especially careful:

Hydraulic Pumps & Motors

The heart of your machine. Even tiny flaws in tolerances can destroy an entire system. Bad pumps don’t just fail—they take other components with them.

Final Drives & Swing Motors

Counterfeits may look identical on the outside, but inside they’re built with margarine and hope.

Pins & Bushings

Soft metal = early wear = sloppy arms and wrecked geometry.

ECU / Electrical Components

You do not want an off-brand control unit sending rogue signals to your boom. That’s how machines become haunted.

Filters & Seals

Knock-off filters often let debris through, or clog too early. Bad seals? Say goodbye to your hydraulic fluid—and your sanity.

How Vikfin Makes Sure You Get the Good Stuff

Alright, enough horror stories. Let’s talk solutions.

At Vikfin, we’ve built our name on real parts, real performance, and no bull. Here’s how we keep you safe from the dark side of the aftermarket jungle:

✅ Rigorous Quality Checks

Every part we stock—used or aftermarket—gets eyeballed, tested, and stripped down by our in-house techs. If it looks suspect, it doesn’t go on the shelf.

✅ Trusted Suppliers Only

We’ve spent years building relationships with legit aftermarket manufacturers that meet or exceed OEM standards. That means:

• Proper tolerances

• Quality materials

• Consistent performance

✅ Full Traceability

We track where every part comes from, what machine it fits, and what condition it’s in. Nothing arrives in mystery boxes. You want proof? We’ve got the paperwork.

✅ Warranties That Actually Mean Something

If something goes wrong—and let’s be real, machines are machines—we stand behind our parts. Full support. No ghosting.

✅ Specialists Who Know Their St**

We’re not just salespeople. We’re ex-mechanics, dieselheads, and problem-solvers. Ask us anything—we’ll tell you straight up if the part you want is worth it.

Can Aftermarket Ever Be Better Than OEM?

Hell yes.

There are aftermarket suppliers out there who specialise in certain components and have refined them beyond what OEM ever bothered with. Think:

• Better seal kits for known OEM weak spots

• Upgraded metals or heat treatments

• Components made for African conditions (read: hot, dusty, abused)

But again—you need to know where it’s coming from.

At Vikfin, we don’t just sell you the part. We explain it. Why it’s good. Why it fits. And what kind of machine abuse it can take.

So… Should You Ever Buy Cheap Parts?

Here’s the rule:

If it’s cheap, simple, and non-critical? Fine. If it’s structural, hydraulic, electronic, or mission-critical? Don’t gamble.

You wouldn’t buy budget bungee cords. Or discount parachutes. Same logic applies to the parts that keep 30 tons of steel from flipping over.

Wrap It Up: Play Stupid Games, Win Stupid Excavator Bills
