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

When you’re repairing or maintaining an excavator, choosing the right parts comes down to one question: Am I getting a genuine OEM part, or a cheap aftermarket imitation? That question matters because the difference between the two is HUGE. A genuine OEM component will last longer, fit perfectly, protect your machine, and deliver the performance the manufacturer intended. A bad aftermarket imitation can ruin an engine, damage a final drive, or create safety problems on site.

Hydraulic systems are the heart of an excavator.Power, precision, lift capacity, digging strength — it all comes down to one thing: The hydraulic oil you choose. Pick the right oil, and your pumps, valves, cylinders, and final drives last thousands of extra hours.Pick the wrong oil, and you’ll destroy components faster than any operator mistake can. Most excavator owners know oil matters — but very few understand why  it matters.This blog breaks down the science, the logic, a

(An educational, step-by-step guide for anyone purchasing used OEM final drives in South Africa) A final drive isn’t just another excavator part.It ’s the heart  of your machine’s travel system — and one of the most expensive components you’ll ever replace. Buying used OEM final drives is one of the smartest ways to save money… if  you know how to check their condition properly. Because let’s be honest:A final drive can look fine on the outside and still be an expensive disas

(Educational, clear, practical — written for real excavator operators and buyers in South Africa) When you walk into a parts yard or message a supplier, the first thing they’ll ask isn’t your excavator’s colour, bucket size, or where it last got stuck in the mud.They’ll ask you one thing : “Do you have the OEM part number?” For many machine owners, that question instantly triggers panic. They flip open a manual from 2004, scratch their heads, and pray the number they send isn

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

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,

Every excavator part has a story. Some live long, some die young, and some soldier on through rebuild after rebuild until they finally give up and get thrown onto the scrap pile behind a workshop in Germiston. Understanding the full lifecycle of an excavator component  helps you: plan maintenance better budget more accurately know when to repair instead of replace avoid catastrophic failures buy smarter when sourcing used OEM parts Most failures don’t come out of nowhere — th

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

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

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

Sawubona, truth-seekers and wallet-watchers. Ralph and Justin here, standing in the middle of the Benoni strip yard with two identical Komatsu PC400-6 final drives on the bench: Left bench: genuine Komatsu OEM final drive, 9 800 hours, pulled from a low-abuse coal loader. Price from Vikfin: R48 000. Right bench: brand-new Chinese aftermarket copy bought by a customer who “saved” R28 000 up-front. Ran 2 410 hours. Now looks like it lost a fight with a blender. We’ve stripped,

Howzit, undercarriage warriors. Ralph in Benoni and Justin in Cato Ridge here. Between us we’ve measured more than 1 200 sets of 20–45 tonne undercarriages in the last eight years, and we’ve got bad news and good news. Bad news: the average South African 40-tonner is throwing away R800 000–R1.4 million on undercarriage every 6 000–8 000 hours because of lazy habits and dealer scare tactics. Good news: the top 10 % of operators in this country are getting 11 000–15 000+ hours

Howzit, legends of the dig. Ralph in Benoni and Justin in Cato Ridge here. Between us we’ve personally stripped 47 Komatsu PC400-series (Dash-6 right up to Dash-8M0) and 38 Hitachi ZX450/ZX470/ZX490 machines since 2018. That’s 85 complete 40-tonne carcasses turned into pallets of parts that are earning contractors money from Kathu to Kitwe right now. We’re not brand fan-boys. We sell whatever walks through the gate. But when the numbers are this one-sided, we have to call it.

Howzit, legends. Ralph here from the Benoni yard. Right now I’ve got three final drives on the bench: one that came in yesterday completely seized, one that’s leaking like a politician’s promise, and one that’s perfect inside despite 14 000 hours. All three are from 30–40 tonne machines. All three could have been saved for pocket money. In the last 18 months we’ve sold 87 final drives out of these two yards. Every single failure story starts with one (or more) of the same sev

If someone has ever handed you a R280 000 + VAT quote for a brand-new main hydraulic pump and told you “it’s the only safe option”, then congratulations: you’ve just been sold the most expensive myth in South African earthmoving. My name is Ralph – I run the Benoni yard in Gauteng and I’ve got a Komatsu K3V180 pump sitting on the bench right now that we pulled out of a PC400-6 two weeks ago. It’s cleaned, resealed, photographed from every angle and priced at R36 500 ex-VAT. T
