Powerhouse in Pieces: Vikfin Strips a Hitachi ZX520 for Premium Used Excavator Parts

When a machine as mighty as the Hitachi ZX520 rolls into Vikfin’s yard, you know something serious is about to happen. This isn’t your average teardown. This is a mechanical autopsy—the careful dismantling of one of Hitachi’s most powerful heavy-duty excavators to give new life to other machines still out there doing the hard yards.

For contractors, operators, and fleet managers across South Africa, this is big news. Because every time Vikfin strips a giant like the ZX520, high-demand components flood the market—original Hitachi quality, tested, cleaned, and made affordable again. Whether you’re rebuilding, replacing, or upgrading, this is your chance to grab premium excavator parts before they disappear.

In this blog, we’ll take you inside the strip-down process, show what makes the ZX520 such a beast, explore the top parts available, and explain why buying used excavator parts from Vikfin is one of the smartest financial and operational decisions you can make.

Meet the Giant: The Hitachi ZX520 Excavator

The Hitachi ZX520 isn’t just another piece of machinery—it’s a powerhouse built for endurance and precision. We’re talking about a machine that tips the scales at around 50 tonnes, driven by a high-torque Isuzu 6WG1 engine pushing close to 350 horsepower. This model was designed for extreme duty—quarrying, large-scale earthmoving, and mining operations.

Hitachi’s engineering philosophy is clear in the ZX520:

• Durability: Reinforced undercarriage, thick-plate boom and arm design.

• Efficiency: Hydraulic systems that maximize dig force while minimizing fuel burn.

• Operator comfort: Advanced cabin isolation, visibility, and intuitive controls.

• Reliability: Minimal downtime, exceptional hydraulic consistency, and rock-solid performance.

But even the strongest machines have their limits. After thousands of hours of service, wear and tear start to take their toll. That’s where Vikfin steps in—to recover, refurbish, and redistribute the value packed inside these mechanical titans.

Why Strip the Hitachi ZX520?

The short answer: it’s too valuable not to.

When an excavator reaches the end of its operational life or becomes uneconomical to repair, it’s not the end of its usefulness. In fact, it’s the beginning of another. Machines like the ZX520 are loaded with high-demand, long-lasting components—from hydraulic cylinders to travel motors—that still have years of life left in them.

By stripping the ZX520, Vikfin ensures:

• Nothing goes to waste. Components are salvaged, tested, and reconditioned.

• Cost savings for customers. Used OEM parts offer massive savings over new.

• Availability of rare parts. Some components on older Hitachi models are hard to source.

• Environmental responsibility. Recycling mechanical parts reduces waste and manufacturing emissions.

This process isn’t random—it’s a precise, methodical dismantling operation carried out by trained technicians who understand every bolt, line, and fitting of the ZX520.

Inside the Strip-Down: How Vikfin Does It

Stripping a 50-tonne excavator is not a backyard job—it’s a technical operation that demands precision, safety, and expertise. Here’s what happens once a ZX520 arrives at the Vikfin yard:

Step 1: Inspection and Documentation

Before a single bolt is turned, the machine undergoes a full diagnostic and visual assessment. Every functional and damaged area is documented, ensuring that every viable component is identified. Serial numbers are logged for traceability.

Step 2: Fluid Drainage and Decontamination

All oils, fuels, and hydraulic fluids are safely drained and disposed of or recycled in compliance with environmental standards. Clean components make the process safer and more efficient.

Step 3: Component Disassembly

Major systems are separated in stages:

• Engine and powertrain removed as a unit.

• Boom, arm, and bucket linkages detached.

• Hydraulic pumps and main control valves extracted.

• Travel motors, final drives, and swing motors carefully removed and tagged.

• Cab, wiring, and electronics separated and stored for parting.

Each major component is cleaned, pressure-tested, and sorted according to condition.

Step 4: Testing and Grading

Vikfin doesn’t just sell used parts—it sells verified parts. Each component is tested for performance:

• Hydraulic pumps undergo pressure and flow testing.

• Final drives and swing motors are bench tested.

• Engines are compression-tested and inspected for leaks.

• Cylinders are checked for scoring, leaks, and seal integrity.

Each part is then graded:

• A-Grade: Excellent condition, fully operational, minimal wear.

• B-Grade: Good condition, tested and reliable, moderate wear.

• C-Grade: Repairable or usable for parts.

This system helps customers buy with confidence—knowing exactly what they’re getting.

Step 5: Cleaning, Labeling, and Storage

Once approved, parts are cleaned, tagged, and stored in Vikfin’s organized warehouse. From here, they’re ready for dispatch anywhere in South Africa—or exported internationally.
