Sawubona, boet! The Vikfin yard in Benoni is looking like a Komatsu Christmas tree right now. We’ve just put the finishing touches on stripping a proper high-hour Komatsu PC400-6, and the result is one of the fullest 40-tonne parts spreads we’ve had all year. The engine walked out the door within 48 hours (R128 000, thank you very much), and the main valve bank went to a mine in Mokopane yesterday, but literally everything else is still here, steam-cleaned, photographed, pric

Excavator engines used to be simple: give them diesel, give them air, give them oil, and they would run until the world ended. But that era is long gone. Today’s excavators—from CAT, Komatsu, Volvo, Doosan, Hyundai, Hitachi, Kobelco, Case, JCB , and others—depend on an unassuming black box that quietly controls everything: the ECU  (Engine Control Unit). The ECU is the brain, the referee, the conductor, the nervous system, and sometimes the silent troublemaker behind 70% of m

If you run excavators, supply excavator parts, or simply deal in soil, rock and steel on a regular basis, your bucket is everything . For the team at Vikfin—South Africa’s leading used excavator-parts supplier—it’s one of the most critical attachments in the business. And if you’re in the market for a used excavator bucket, or thinking about re-selling or refurbishing one, then buckle up: this blog dives deep into types, wear-and-tear, maintenance, fitment, and the all-import

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,

Field Edition — Practical Guide for Everyday Operators 1. INTRODUCTION Congratulations — you’re in control of one of the most powerful and versatile pieces of machinery on any site.This manual will help you operate your excavator safely, efficiently, and with confidence. It covers: Basic machine knowledge Daily inspections and maintenance Safe operating techniques Working on different terrains Transporting and parking Emergency procedures Whether you’re a new operator or an o

When you watch an excavator in action, it’s easy to focus on the big stuff — the roaring engine, the swinging boom, the bucket biting into the earth. But behind every precise movement, there’s a powerhouse component working under immense pressure to make it all happen: the dipper arm cylinder . It’s one of those parts that most operators only think about when it starts leaking — but by then, you’re already losing power, precision, and money. At Vikfin , South Africa’s trusted

When it comes to excavators, most operators think power means horsepower, torque, or hydraulic muscle. But there’s another kind of power hiding down below — one that doesn’t get the spotlight but literally keeps the whole machine moving. It’s the track adjuster , and without it, your excavator wouldn’t get far. This small but mighty component ensures your tracks stay tight, your undercarriage stays aligned, and your productivity stays on track — literally. At Vikfin , South A

If you’ve ever stood on a construction site and watched two excavators side by side — one with steel tracks grinding through the mud and another with rubber tyres rolling smoothly over asphalt — you’ve probably wondered: Why the difference? It’s not just about looks. The choice between a steel-tracked excavator  and a wheeled excavator  completely changes how the machine behaves, what kind of terrain it can handle, how it’s maintained, and even how the operator should think b

When you’re in the market for a hydraulic excavator, there’s one question that always rises to the surface before anything else: Do you go for a wheeled excavator or a tracked one? Both look similar from a distance — a powerful boom, a bucket, and that familiar rotating cab — but what lies beneath makes all the difference. Whether you’re digging trenches, clearing debris, or handling material on a construction site, the type of undercarriage (wheels or tracks) determines how

Your excavator’s engine isn’t just another component — it’s the heart of your machine. When it’s healthy, everything else flows smoothly: power, productivity, and profit. But when it starts to struggle, the whole operation suffers. And here’s the kicker — most engine failures aren’t sudden. They’re slow-motion disasters caused by neglect, shortcuts, or the wrong parts. In this post, we’ll unpack exactly how engine wear creeps up on you, how preventative maintenance keeps mone

When your excavator goes down, the clock starts ticking — and every minute of downtime costs you money. The pressure is on, and the temptation is real: you find a cheaper, non-OEM part online, it looks close enough, and you think, “How bad could it be?” Well… bad enough to cost you an engine, a final drive, or your next big contract. Mixing non-OEM (aftermarket) parts into an excavator designed with precise OEM tolerances is like putting cheap tyres on a Ferrari. It might rol

There’s one sound every excavator operator dreads — the grinding, groaning death rattle of a failing final drive. It’s like your machine is screaming for mercy while your wallet quietly cries in the corner. The final drive is the powerhouse of your excavator’s movement system. It transfers hydraulic power into track rotation — which means when it goes, your entire machine goes with it. No tracks, no work, no profit. And yet, it’s one of the most commonly neglected — and most

If you run excavators in South Africa, you already know: keeping them moving isn’t just about buying machines — it’s about keeping them alive.And when things break (because they will  break), your real profits come down to one question: “Can I get quality replacement parts — fast and affordably?” That’s where two of the biggest names in the industry come into focus: Volvo  and Doosan . Both are powerhouse brands with loyal followings, solid engineering reputations, and huge g

When you think about what kills profitability in the heavy equipment game, you probably picture catastrophic breakdowns — snapped hydraulic lines, seized engines, or a final drive that decides to commit suicide mid-project. But here’s the truth most operators learn too late: It’s not the big failures that drain your profits. It’s the small, silent ones — like leaks. That tiny drip of hydraulic oil? That faint smell of diesel? That slow coolant loss you top up once a week? The

In today’s world, efficiency  isn’t just about how much dirt your excavator can move in an hour — it’s also about how smartly you run your operation. And part of running smart means thinking about sustainability. Construction and mining companies are under growing pressure to reduce waste, limit emissions, and cut their environmental footprint — all while staying profitable. But there’s a simple, powerful way to do both: using used OEM excavator parts . When you buy from Vikf

In the construction game, downtime  is the enemy. When your excavator’s parked instead of digging, every minute costs you money — in idle crews, missed deadlines, and lost contracts. But there’s one simple, smart way to slash downtime without breaking the bank: using used OEM excavator parts  from a trusted supplier like Vikfin . Let’s break down exactly how  genuine OEM parts — even used ones — can keep your machines in the dirt and out of the workshop. 1. Perfect Fit, Every

Every powerful excavator you see on site — roaring, digging, breaking — is a collection of thousands of precision-engineered parts working together. But what happens when one of those machines reaches the end of its life? Does it all go to waste? Not at Vikfin. Behind every used OEM part that leaves our warehouse, there’s a story — a process that starts long before it lands in your hands. It’s a story of engineering precision, grit, and South African know-how. This is the sec

In the earthmoving world, profit margins can be razor thin. Between fuel prices, operator wages, site delays, and maintenance, it doesn’t take much for a good month to turn bad.But there’s one area where you can make massive savings  without compromising performance — and that’s your parts strategy. If you’re still paying top dollar for new OEM parts or gambling on cheap aftermarket ones, you’re missing the sweet spot: tested, used OEM excavator parts  from a reputable suppli

Buying used excavator parts can be like walking through a scrapyard minefield — full of hidden gems and total junk, often side by side. One part could save your project thousands; the next could cost you your machine. In South Africa’s tough construction scene — where margins are tight and downtime kills — knowing how to tell a high-quality used OEM excavator part  from a worn-out dud isn’t just good business sense. It’s survival. This guide from Vikfin , South Africa’s leadi

When it comes to the anatomy of an excavator, most operators and mechanics immediately think about the boom, bucket, or hydraulic pump. But deep inside the undercarriage and swing frame lies one of the most critical — yet least appreciated — structural components of the whole machine: the X-frame . It doesn’t move oil or lift dirt, but the X-frame  forms the structural spine  of your excavator’s lower body. It’s what keeps the tracks properly aligned, the upper structure stab
