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

Stop Wasting Time, Money, and Sweat on Half-Assed Repairs Let’s get straight to the point: Most contractors are terrible at this .They stand over a busted final drive, hydraulic pump, or swing motor and say, “I think we can fix it.” And then three days later, the machine is still broken, your operator is pissed, the client is furious, and your wallet is getting fleeced faster than diesel prices. Here’s the brutal truth: some parts are worth repairing. Most aren’t. If you don’

Stop Waiting for a Catastrophe — Catch It Before It Costs You a Fortune Let’s not sugarcoat it: final drives are expensive, critical, and delicate . Most contractors only notice they’re failing when the machine stops moving, oil sprays everywhere, and panic sets in .

A Brutally Honest Guide for Contractors Who Are Tired of Being Screwed Over Let’s not dance around it. The used excavator parts market in South Africa is a jungle —and most suppliers are hyenas. You already know the type: “We’ve got stock” (they don’t) “It’s 100% OEM, boss” (it’s not) “Machine was running” (it wasn’t) “We’ll courier it today” (nope) “Looks the same, so it should fit” (it won’t) If you’ve been in the construction or plant hire game for more than five minutes,

A Hard-Hitting, South African, Contractor-to-Contractor Reality Check Let’s cut the crap. Every contractor in South Africa thinks  they understand the cost of downtime… until their excavator dies in the middle of a job, the client starts phoning every hour, and their crew stands around scratching their balls while billable hours burn like tinder. Most guys only count the price of the replacement part.R5,000 here. R12,000 there. Cute. But that’s not the real cost.Not even clos

This little device does big work , protecting your hydraulic system, extending the life of components, and preventing catastrophic failures.

Stop Guessing — Understand the Mechanics Before You Break Your Machine If you think turning a steel-tracked excavator is as simple as “push one track forward and pull the other back,” think again.

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.

The tough truth: not every broken part is worth repairing. But how do you know which ones are? This guide walks you through practical, hands-on ways  to decide whether to repair or replace a component — saving time, money, and headaches on South African sites.

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

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

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

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

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),
