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

A Practical, No-Nonsense Guide for South African Contractors If there’s one thing that can bring an excavator to its knees faster than a blown hose or a leaking final drive, it’s an overheating hydraulic system. Not only does it slow down your productivity, but it also puts every major hydraulic component at risk: pumps, motors, cylinders, seals, and even the hydraulic oil itself. And here’s the catch — overheating is almost always preventable. This guide breaks down why exca

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

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

When excavator owners complain about undercarriage wear, they usually blame the terrain, the operator, the machine brand, or even the weather.But the number one undercarriage killer — the silent assassin — is something far more basic: Incorrect track tension. Too tight → burns money.Too loose → causes damage.Just right → extends life dramatically. In this educational deep dive, you’ll learn exactly  how track tension works, why it affects every major undercarriage component,

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

Because Cheap Pumps Are the Fastest Way to Turn Your Excavator Into an Expensive Garden Ornament Let’s get something straight right from the start: If you buy a cheap aftermarket hydraulic pump for your excavator, you’re not “saving money.”You’re delaying the pain . And when that pain hits, it hits hard — blown hoses, slow hydraulics, cooked oil, trashed cylinders, destroyed spool valves, and a machine that suddenly works like it’s got emphysema. Hydraulic pumps are the heart

Behind the Scenes of Keeping SA Excavators Alive If you think selling used excavator parts is just about storing a bunch of old engines, pumps, and final drives in a dusty warehouse, think again. A day at Vikfin  is chaos with a method, grit with precision, and coffee-fueled decision-making on a borderline heroic scale. Let’s take you behind the scenes — so you can see exactly why South African contractors trust us over any backyard operator or online auction snake oil salesm

Because Some “Rebuilt” Parts Belong in a Scrap Bin — Not Inside Your Machine Let’s get brutally honest: The word “rebuilt”  gets abused in this industry more than an old rental excavator. Some rebuilt components are excellent  — done by real professionals using genuine OEM specs and proper tolerances. But others? They’re slapped together in a backyard workshop using whatever parts the rebuilder could find, guess, grind, weld, or pray into place.Those “rebuilt” parts will rob

If You Ignore These Symptoms, Your Machine Is About to Eat Your Wallet Alive Let’s be brutally honest: when a final drive fails, it’s almost never “sudden.”It’s never “unexpected.”And it sure as hell isn’t “bad luck.” Final drives warn you .Loudly.Repeatedly.Aggressively. It’s contractors and operators who ignore those warnings — until the machine is limping across the job site like a wounded buffalo and everyone is suddenly shocked that the bill starts at R40,000  and goes u

How to Avoid Costly Errors and Keep Your Excavator Running Smoothly Buying used excavator parts can save a ton of money — if you do it right. But in South Africa, many contractors make mistakes that turn “savings” into unnecessary downtime, wasted cash, and headaches . Let’s break down the top 5 mistakes  contractors make when buying used parts — and how to avoid them. Mistake #1: Not Verifying Part Compatibility This is the most common mistake. Every excavator model has part

Behind the Scenes of Keeping South African Excavators Running Like New If you’ve ever bought a used excavator part and prayed it lasts more than a week, you know the stakes are high. Downtime in South Africa costs real money — sometimes tens of thousands per day. At Vikfin , we don’t leave anything to chance. Every used part goes through a rigorous testing and certification process , so contractors know exactly what they’re getting. Let’s take you behind the scenes — the mess

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

Sawubona, mfowethu! If you’ve ever stood next to a 40-tonne excavator that’s been sitting dead for three weeks waiting for a R280 000 hydraulic pump from Japan, then this 3 000-word deep-dive is written specifically for you. My name is Ralph – I’m one of the guys at Vikfin who actually turns the spanners, drives the forklift, and argues with customs officials so your parts land in Kitwe or Walvis Bay without drama. Today I’m pulling back the curtain on exactly how Vikfin has

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

When you think about maintaining your excavator, you probably picture greasing pins, checking hydraulic hoses, or replacing filters. But here’s a truth that separates the smart operators from the expensive repair stories — oil testing  is one of the most powerful, yet most overlooked tools in extending the life of your machine. In South Africa’s tough working environments — from the red dust of the Northern Cape to the coastal humidity of Durban — your excavator’s oil isn’t j

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

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 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,
