Top 10 Most In-Demand Used Excavator Parts in South Africa Right Now

In South Africa’s hard-hitting earthmoving industry, excavators don’t get a day off. When a critical part fails, downtime can cost thousands per hour. That’s why smart contractors, plant managers, and fleet operators turn to used excavator parts—especially OEM components supplied by trusted players like Vikfin.

Based on real-time sales data, client feedback, and national demand trends, these are the top 10 fastest-moving used excavator parts in South Africa right now. If you’re running a busy site, this is the hit list you want in your back pocket.

🔥 1. Final Drives: The Undisputed King of Wear Parts

Why they move fast:Final drives are among the most abused parts on an excavator. They're constantly under stress from heavy loads, challenging terrain, and poor operator habits. Once one goes, your machine’s mobility is toast. No drive, no movement.

Why customers prefer used:OEM final drives can cost upwards of R150,000 new. Vikfin’s tested and guaranteed used units come in at 40–60% of that price and are usually in stock. No six-week wait from overseas. Just plug, play, and keep digging.

Most in-demand brands: Volvo, Hitachi, CAT, and Komatsu final drives top the charts.

🔥 2. Swing Motors: No Rotation, No Excavation

What they do:Swing motors power the cab’s 360° rotation. Without them, your excavator becomes a sitting duck. Failures are sudden and costly.

Sales trend:In Q1 of 2025 alone, Vikfin saw a 24% increase in swing motor sales, especially for 20–30-ton machines. Construction and demolition crews can’t wait around—they need a working motor yesterday.

Bonus: Swing drives and reducers also spike alongside swing motors, forming a dynamic duo of demand.

🔥 3. Hydraulic Pumps: The Machine's Heartbeat

Why they're critical:Hydraulic pumps power the entire arm movement, from lifting and digging to tilting and extending. Without it, your excavator is just a heavy paperweight.

Why used sells:A new pump from OEMs? You’re easily in for R100,000–R200,000+. Used and rebuilt pumps from Vikfin average R40,000–R70,000 with full pressure testing and a warranty.

Who’s buying?Plant hire firms, municipalities, and mining operations lead the charge.

4. Slew Bearings: The Silent Workhorse

The problem:These large-diameter bearings enable smooth swing function. They often wear out invisibly—until a catastrophic failure occurs.

Why the rush:With limited local suppliers and high import costs, used OEM slew bearings are gold. Especially when downtime threatens project deadlines.

5. Hydraulic Cylinders: Heavy Lifters That Always Get Beat Up

Top sellers:Boom cylinders, arm cylinders, and bucket cylinders—take your pick. They're all highly stressed and often leak, bend, or fail after years of abuse.

Why used cylinders make sense:Instead of waiting weeks for a new import, contractors scoop up refurbished cylinders at less than half the price. At Vikfin, each cylinder is pressure-tested, resealed, and often already fitted with OEM rods.

Hot tip: Komatsu and Doosan cylinders sell out fastest.

6. Engines & Turbochargers: Big Money, Big Demand

Engines:Complete used excavator engines are hot sellers—especially in rebuilds, repowers, or after hydraulic lock disasters.

Turbochargers:As emission standards tighten, turbos get more complex (and expensive). Replacing them new can be ruinous. A rebuilt or gently used unit is a no-brainer.

Best-sellers:CAT C6.6, Komatsu SAA6D107, Volvo D6E, and Isuzu 4HK1.

7. Undercarriage Components: The Bottom Line

Why they wear fast:Think of them as your excavator's shoes. Tracks, rollers, idlers, and sprockets are in constant contact with abrasive surfaces.

Used demand:Contractors love grabbing used OEM undercarriage kits—especially for machines nearing the end of their service life where brand-new components make no economic sense.

Pro tip:Buying a complete set (tracks, rollers, idlers, sprockets) ensures even wear and better performance.

8. Valve Banks & Pilot Pumps: Small Parts, Big Function

What they do:Control the flow of hydraulic oil to different parts of the machine. Pilot pumps regulate pressure and precision—crucial for operator control.

Why they’re trending:Surging rebuild activity and site-level repairs are pushing demand for these nuanced parts. Vikfin stocks hundreds of valve banks that OEMs no longer supply new.

9. Radiators & Cooling Systems: Keep It Cool or Cook It All

The problem:Overheating kills excavators. Summer heat and dust don’t help either. Radiators, oil coolers, and water pumps wear faster in African conditions.

Used wins again:New radiator assemblies are expensive, often special-order. Refurbished or gently used ones at 30–50% cost are flying off the shelves at Vikfin.

10. Cabs, Panels & Electronics: The Unsexy But Essential Bits

Cab replacements:Fire damage, rollovers, and vandalism make cabs a high-demand salvage item. Used ones come with full glass, wiring, and even HVAC components.

Electronics:ECUs, engine management modules, and wiring harnesses are becoming more in-demand as machines grow more digital—and local repair shops struggle to find affordable replacements.

2025 trend:Electronics are now one of the fastest-growing categories in used parts sales.

Why Final Drives, Swing Motors & Hydraulic Pumps Lead the Pack

1. Downtime killers: These parts bring work to a standstill—no contractor can afford to wait.

2. OEM delays: Global supply chains remain sluggish. It’s often 4–6 weeks for new components.

3. Used = Instant availability: Vikfin ships countrywide—often within 24–48 hours.

4. Savings stack up: Customers routinely save 30–75% vs. new.

5. OEM Quality: No dodgy Chinese knock-offs—just proven OEM hardware.

   
   

What’s Driving the Surge in Demand?

• Infrastructure boom: Roads, bridges, and energy projects are creating non-stop demand for reliable machines.

• Mining remains strong: Bulk material handlers are working 24/7—parts wear is high.

• High machine prices: New excavators are 30–50% more expensive due to currency fluctuations.

• Used parts = circular economy: Buying refurbished reduces waste and supports local industry.

• Budget pressures: Municipalities and SMEs are trying to do more with less.
