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.

(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

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

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 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

When you think about an excavator’s hydraulic system, the first parts that come to mind are usually the pump, the cylinders, and the control valves. These are the muscle and the brains of the machine’s movement. But sitting quietly between the engine and the hydraulic pump is an often-overlooked hero — the pump bell housing . It may look like a simple chunk of cast metal, but the bell housing plays a critical structural, alignment, and vibration-damping role  that directly im

You’ve probably heard it before: “Oil is the lifeblood of your machine.”It’s not just a catchy saying—it’s literal truth. For an excavator, oil testing isn’t some optional extra you do when you’ve got time. It’s an essential diagnostic tool that tells you what’s going on inside the machine long before you hear the first grind, smell the first burn, or see the first warning light. Skipping oil testing is like ignoring your own blood test results because “you feel fine.” The re
