Legends of the Loaders: A Generational Tale of the Komatsu WA600, CAT 988, and Volvo L350

Back in the dusty mining pits of the late 1980s, three giants began carving their names into the earth Komatsu, Caterpillar, and Volvo. Each had a different philosophy, a different rhythm, and a different vision of what a wheel loader should be.

This isn’t just a comparison of numbers and specs. It’s the story of how three machines evolved, aged, and adapted over nearly four decades. From roaring mechanical beasts of the ‘80s to the smart, fuel-efficient titans of today, the WA600, 988, and L350 have all traveled a long road—and we’re here to tell that story.

 

 

 

 

 

 

 

 

The Iron Age – The 1986 Originals

A year of Walkman's, diesel fumes, and machines built to last a lifetime.

Komatsu unveiled the WA600-1, a bold, muscular loader with almost no electronics and an engine that could pull the earth backwards if needed.

Caterpillar was pushing the 988B/C series, sturdy and dependable, with its legendary mechanical reliability.

Volvo, still shaping its identity in the large loader class, fielded the early L330/L360 series—precursors to what would eventually become the L350 line.

These machines were built not for comfort, but for war. No touchscreen. No hybrid systems. Just raw power, thick steel, and enough torque to make the ground tremble.

Aftermarket & OEM in Today’s World:

Today, these legends still roam the yards of Africa, the Middle East, and rural America. But keeping them alive takes work:

Caterpillar 988B/C: Still king in aftermarket. Brands like CTP, IPD, and FP Diesel keep parts in circulation. Even Cat dealerships can still supply many core components.

Komatsu WA600-1: Some parts available through Japan-based surplus dealers and aftermarket specialists like KMP or H&B. But others? Out of print.

Volvo L330/360: A challenge. OEM support is almost gone, and aftermarket parts are scarce or overpriced. Most owners rely on salvage units or custom machining.

 

The Evolution (1995–2005) – From Muscle to Mind

As the new millennium approached, something shifted. Mining and quarrying companies wanted more than brute strength—they wanted efficiency, comfort, and cleaner emissions.

Komatsu WA600-3 and WA600-6 entered the scene with better hydraulics, improved visibility, and optional ride control.

Caterpillar launched the 988F and later the 988G, integrating load-sensing hydraulics, better cab ergonomics, and the first generation of what we now call "smart machines."

Volvo answered with the L330D, then the L350F, refining their loader into a powerful yet refined beast, loved especially in Europe for its smooth controls and fuel economy.

This generation of machines struck a balance between old-school durability and new-era operator comfort. And even today, used WA600-6 loaders, CAT 988G for sale, and Volvo L350F units are in high demand on the used equipment market.

 Parts & Maintenance in This Era

CAT 988G/F: Still very strong in parts availability. Many owners rely on high-quality aftermarket brands like CTP or Berco for undercarriage and engine kits.

Komatsu WA600-3/6: Good availability of critical components, especially engine parts. Electronics, however, can be tricky and expensive.

Volvo L350F: Reliable in operation, but parts prices tend to be higher. Volvo's own network supplies most OEM parts, though aftermarket options are growing, especially in Europe.

 

 

 The Smart Machines (2006–Today)

We are now in the age of intelligence. Machines are no longer just tools—they're connected assets with diagnostics, telematics, and emissions systems smart enough to call the mechanic before the driver notices a problem.

The Komatsu WA600-8 arrived with Tier 4 Final emissions, Komtrax telematics, and adjustable power modes for fuel savings.

The CAT 988K brought joystick steering, Product Link remote monitoring, and even hybrid variants for fuel-sensitive operations.

Volvo L350H, with its OptiShift system, ultra-quiet cab, and Eco mode, is arguably the most operator-friendly loader in the class.

These modern giants are expensive but incredibly efficient—ideal for contractors who want reliability with fewer operators and lower fuel bills.

?? Spare Parts and Ownership Cost

Caterpillar 988K: Still the benchmark. OEM parts available globally. Resale value is strong. Aftermarket support is vast and affordable.

Komatsu WA600-8: OEM support is solid through authorized dealers. Aftermarket is growing, though some advanced electronic parts remain exclusive.

Volvo L350H: High comfort, but higher long-term cost due to parts pricing and lower aftermarket coverage. However, fuel savings offset this over time.

 

 

The Parts Puzzle – OEM vs Aftermarket

When it comes to keeping these giants alive, parts availability is just as important as horsepower.

Caterpillar has the strongest global network. Many aftermarket brands like CTP, IPD, and Bulldog offer high-quality alternatives at better prices. Even for 988B models, parts are still being reproduced.

Komatsu's WA600 parts are well-supported by OEM and aftermarket alike—especially brands like KMP, H&B, and OEM surplus dealers in Japan and the UAE.

Volvo L350 parts can be a challenge. OEM parts are reliable, but expensive. Some aftermarket suppliers like VMR or CVA exist, but coverage is patchy.

Also note:

CAT often supports parts for 20+ years after production ends.

Komatsu generally supports 12–15 years.

Volvo’s parts support tapers after 10–12 years unless the machine is still in active production.

 

 Verdict of the Yard – Which Loader Is Right for You?

So, which legend wins?

Choose the CAT 988 if you want rock-solid parts support, a trusted resale value, and strong aftermarket flexibility. Great for contractors in Africa, UAE, and the Americas.

Choose the Komatsu WA600 if you’re looking for a balance between durability and technology—especially if you’re sourcing parts from Asia or the Gulf region.

Choose the Volvo L350 if comfort and operator productivity are your top priorities, and you’re prepared for a slightly higher parts bill.

Final Thoughts
From the WA600’s raw beginnings to the L350H’s sophisticated comfort, these loaders each tell a story of engineering evolution. Whether you're restoring a 1986 Komatsu WA600-1, running a CAT 988K fleet, or investing in a used Volvo L350H, the key is knowing the history—and the hidden costs.
