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

Howzit, grease monkeys, site foremen and anyone who’s ever stared at a R280 000 quote for a new valve bank and felt physically sick. Ralph and Justin here from Vikfin – one of us is in Benoni stripping in the Gauteng dust, the other is in Cato Ridge doing the same under KZN humidity. Between us we’ve pulled more than 600 valve banks out of 20–45 tonne machines in the last ten years and sold every single one without owning a single test bench. We’re going to give you the full,

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

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
