Volvo excavators have a well-earned reputation for smooth, precise swing control. But that precision comes at a cost: when something goes wrong, the fault is often not obvious , and the swing motor is frequently blamed when it’s innocent. At Vikfin, we see this constantly on Volvo EC machines—EC210, EC240, EC290, EC360, and EC480 especially. This guide breaks down Volvo-specific swing motor failures , how their systems differ from other brands, and how to diagnose them withou

An Educational Guide for Excavator Owners, Mechanics & Fleet Managers in South Africa Turbochargers are one of the hardest-working components on any excavator engine. They spin at over 100,000 RPM , survive extreme heat, and feed the engine the extra air it needs to produce torque under heavy load. But here’s the part most people get wrong: A turbocharger is not just a “bolt-on part.” It’s a precision-engineered system that must match the engine’s airflow, exhaust pressure, t

An Educational Guide for Excavator Owners, Operators & Fleet Managers in South Africa The final drive is one of the most abused—and most expensive—components on any excavator. It’s the muscle that turns your tracks, pushes the machine through mud, climbs slopes, and rotates under load. And yet, most failures don’t come from “bad luck” or “a weak part.” They come from operation .How the machine is driven matters just as much as what’s inside the gearbox. At Vikfin, we’ve seen

Hydraulics are the beating heart of your excavator. You blow that system, and you’re not just dealing with a repair — you’re dealing with a full-scale financial ambush. Operators complain about fuel costs, attachments, labour, insurance… but the one thing that quietly drains bank accounts across South Africa is poor hydraulic maintenance . And yes — it’s avoidable.And yes — most contractors know better.But no — they don’t do better. This blog breaks down exactly how skipping

Counterfeit excavator parts are becoming a global plague — and South Africa is no exception. They look like OEM. They’re packaged like OEM. Some are even stamped like OEM. But inside? They’re time bombs. Cheap metals, sloppy tolerances, low-grade seals, and zero quality control. The worst part?Contractors buy them thinking they’re getting a “good deal.”Then their machine detonates three jobs later — and suddenly that “cheap” part becomes the most expensive decision they’ve ma

An Educational Guide for Excavator Owners & Fleet Managers in South Africa When an excavator fails, most people blame the “big” components: The engine The hydraulic pump The final drive The swing motor But in reality, the silent killer behind most of those catastrophic failures isn’t the component itself. It’s dirty oil . Contaminated oil destroys engines, pumps, valves, and motors faster than any other factor—and it often goes unnoticed until thousands of rands evaporate in

Save Money, Reduce Downtime, and Get OEM Reliability Without Paying OEM Prices When an excavator breaks, you’ve got two problems: the machine is down, and your wallet is about to cry. Modern OEM parts are insanely expensive — especially from brands like Volvo, CAT, Komatsu, Hitachi, Doosan , and Hyundai . Even simple components can cost more than the entire machine is worth if it's older or high-hours. But here’s the truth smart contractors understand: Some excavator parts ar

How to Make Sure You’re Getting the Best OEM Components (and Not Expensive Scrap Metal) Buying used excavator parts can save your business a ton of money — but only if you know how to identify what’s high-quality and what’s a ticking time bomb . The harsh reality of the used parts world is this: There’s good stock…There’s bad stock…And then there’s the absolute horror show that some sellers try to pass off as “good condition.” At Vikfin, we’ve built our entire reputation on s

When you look under the hood of many Japanese excavators — and quite a few Korean and European machines — there’s a good chance you’ll find a Mitsubishi engine quietly doing its job. Mitsubishi’s industrial diesel range has earned a reputation for reliability, simplicity, torque-rich performance, and long service life. Whether you’re running a 1.5-ton mini excavator or a 20-ton earth-mover, Mitsubishi has produced an engine for that class. This extended guide dives into the f

Let’s cut through the marketing bullshit: when you see a giant excavator, wheel loader or other earth-moving beast in South Africa (or anywhere), there’s a very good chance the engine heart under the hood comes from Perkins — a company owned by Caterpillar. Their relationship shapes how big machines move dirt.We’ll trace: the history of Perkins, how Caterpillar acquired it, why it matters for earth-moving gear, the technical/repair implications (our bread & butter at Vikfin),

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

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

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

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
