Volvo, Hitachi, or Komatsu? Matching the Right Used Parts to the Right Machine

Ever tried to fit a Komatsu final drive on a Volvo excavator?It’s like trying to install a Toyota Hilux gearbox into a Land Rover Defender—possible, maybe, but you're going to need black magic, custom brackets, and a therapist.

When it comes to buying used excavator parts, one of the biggest (and most expensive) mistakes operators make is buying parts that don’t quite fit. Or worse, forcing them to fit. You don’t want to be that guy with a Frankenstein excavator held together by cable ties and hope.

So today we’re cutting through the confusion and helping you match Volvo, Hitachi, or Komatsu machines with the right used parts—without wasting time, money, or bolts you’ll never find again.

Why Matching Matters (Seriously, It Does)

Here’s the brutal truth: just because something looks like it fits, doesn’t mean it actually does.

Excavator parts are brand-specific, model-specific, and often even serial number–specific. A swing motor from a Komatsu PC200-6 might look identical to one from a PC200-7—but internally, they could be as different as a bakkie and a Boeing.

Mismatched parts can lead to:

• Premature failure

• Leaks, overheating, or poor performance

• Complete machine downtime

• Voided warranties

• You screaming into the void

The good news? Matching used parts to the right brand and model isn’t rocket science. Especially when you're armed with the right info and a supplier who actually knows their stuff (yes, we’re looking at you, shady Facebook Marketplace guy).

Let’s Talk Brands: What Makes Them Different

Every major excavator brand has its own engineering quirks—just like every biltong shop has its own “secret spice.”

1. Volvo – The Swedish Precision Freak

Volvo machines are built like tanks… but with IKEA-level engineering precision. Their parts are:

• Highly specialized

• Engineered for comfort and efficiency

• Often embedded with sensors and electronics

• Priced like they were made of unicorn dust

👉 Matching tip: Always check the part number. Volvo machines are notoriously sensitive to compatibility issues, especially on newer models. Even final drives can have different bolt patterns and internal gear ratios between seemingly identical models.

2. Hitachi – The Silent Samurai

Hitachi excavators are known for reliability, fuel efficiency, and quietly getting the job done. But their parts can be sneaky:

• Many models share parts with John Deere (especially in North America)

• Older machines are more forgiving; newer ones less so

• Some components are interchangeable between Dash series—but not all

👉 Matching tip: Use your serial number religiously. That’s the golden key to avoiding mismatches. Bonus points if your used parts supplier can cross-reference Hitachi and Deere interchange codes.

3. Komatsu – The Japanese Workhorse

Komatsu is one of the most popular brands in South Africa, and for good reason:

• Solid, reliable machines

• Huge local market = more used parts available

• Modular designs = some cross-model compatibility

But don’t get lazy. Komatsu still hides some curveballs.

👉 Matching tip: Always check machine series (e.g., -6, -7, -8). Even small changes in pump pressure or gear size can mess up your whole system.

What Parts Are Most Commonly Swapped—and Most Commonly Mismatched?

Let’s break it down by the most in-demand used parts:

Part	Common Mistake	Matching Tip
Final Drives	Looks identical but wrong gear ratio	Match by model, series, and tooth count
Swing Motors	Wrong spline size or port thread	Get flange dimensions + serial number
Track Motors	Bolt pattern doesn’t align	Confirm motor code stamped on the housing
Hydraulic Pumps	Flow rate mismatch = disaster	Check the displacement (cc/rev) and pump brand
ECU/Control Units	Wrong software version	Serial number essential—no guessing!
Cabs and Body Panels	Mounting brackets differ across years	Send photos and measurements
Radiators	Inlet/outlet mismatch	Compare diagrams or bring the old one in
Undercarriage (Idlers, Rollers)	Different sizes across similar models	Measure center-to-center distance precisely

How to Match Like a Pro (Even If You're Not One)

Here's a step-by-step guide to becoming a part-matching legend:

Step 1: Know Thy Machine

Sounds obvious, but you’d be surprised how many operators don’t know the full model and serial number of their own machines. Don’t guess—go check the VIN plate.

Write down:

• Make (Volvo, Hitachi, Komatsu)

• Model (e.g., PC200-7)

• Serial number (e.g., KMTPC123P99A12345)

• Year of manufacture (if known)

Step 2: Take Clear Photos

Snap photos of the part you need:

• From all angles

• Including any stamped numbers

• Showing bolt patterns or connectors

Bonus: A photo of where it fits in the machine can save everyone a headache.

Step 3: Call a Specialist Supplier

Don’t just Google “used final drive” and click the first result. Call a supplier that specializes in excavator parts—not a general breaker yard.

Ask:

• “Do you have a part for [make, model, series]?”

• “Is it tested?”

• “Can I return it if it doesn’t fit?”

• “Do you offer startup warranty?”

If they say “umm…” more than once—hang up and try someone else.

Step 4: Cross-Check Part Numbers

If you’ve got the OEM part number (or even better, the part itself), ask your supplier to cross-reference it.

Good suppliers use systems that show interchangeable parts across:

• Models

• Years

• Global specs

This is where used parts suppliers like Vikfin shine. We’ve been elbows-deep in these machines for years. We know what fits—and what almost fits (but will cost you dearly).

Real-Life Matching Disasters (Don’t Be These Guys)

Let’s learn from a few anonymous “friends” who got it wrong:

🚫 Guy #1: Tried to install a PC210 final drive into a PC200. It fit, but ran hot and failed in 50 hours. Turns out the gear ratio was wrong. He bought it off a guy “with a bakkie and a Facebook page.”

🚫 Guy #2: Ordered a swing motor for a Volvo EC210B, received one for an EC210C. Almost identical—but ports were mirrored. Fitter tried to reroute hoses. One popped. Machine caught fire. Insurance didn’t pay out.

🚫 Guy #3: Bought an “ECU for a Hitachi ZX200.” Plugged it in. Machine wouldn’t start. Turned out it came from a ZX200LC, different firmware. Took two weeks and a reprogramming session to sort it out.

Moral of the story? Close isn’t good enough.

What a Good Supplier Does for You

When you deal with a pro, you’re not just buying a part—you’re buying peace of mind.

Here’s what a quality used excavator parts supplier will do:

✅ Ask for full machine details✅ Cross-reference part numbers✅ Provide actual photos of the part✅ Confirm compatibility✅ Offer returns or exchanges✅ Pressure-test or bench-test key components✅ Give advice based on real-world experience

At Vikfin, we’ve helped guys who’ve accidentally bought left-hand travel motors for right-hand sides, final drives that rotated the wrong direction, and even cabs that wouldn’t bolt down without cutting steel.

We helped them fix it—and we’ll help you avoid it in the first place.

Final Word: The Right Part = The Right Result

Used parts are a smart way to save money, reduce downtime, and keep your fleet running lean. But only if you get the right part for your machine.

So whether you’re running:

• A Volvo EC210,

• A Hitachi ZX200, or

• A Komatsu PC300,

Make sure your supplier knows more than just the brand.

A good match saves you time.A perfect match saves your job.A bad match? That’ll cost you twice.
