One old excavator can become dozens — sometimes hundreds — of opportunities to keep other machines working. What happens when an excavator reaches the end of its working life? Most people see scrap. We see inventory. More specifically, we see engines, hydraulic pumps, final drives, slew motors, valve banks, cylinders, radiators, tracks, electrical components, cabs, counterweights, attachments and hundreds of smaller components that can potentially give another machine a secon

The cheapest excavator part isn't necessarily the one with the lowest price. It's the one that gets your machine working again. If you operate excavators for a living, you already know that downtime is expensive. What you may not always appreciate is just how expensive it can be. A machine standing in your yard isn't earning money. A machine standing on a construction site isn't moving material. A machine sitting on a mine isn't producing. A machine parked in a quarry isn't c

Your excavator has stopped working. The operator is standing around. The project is waiting. The client is getting impatient. And you're on the phone trying to find a part. The first question you're probably asking is: “How much is the replacement part going to cost?” It's an important question. But it might not be the most important one. The bigger question is: “How much is this excavator costing me while it is standing still?” Because a broken excavator doesn't simply cost

Your excavator needs a new final drive. The dealer quotes you R250,000. You nearly fall off your chair. So you start shopping around. Someone offers you an aftermarket unit for R140,000. Another supplier says they have a used OEM unit for R85,000. Someone else tells you they can refurbish your existing final drive for R110,000. Four options. Four prices. Four very different propositions. So which one should you buy? OEM? Aftermarket? Refurbished? Used? The answer isn't as sim

That old excavator sitting in the corner of your yard might be worth more than you realise. It doesn't run. The tracks are worn. The paint is faded. The cab looks like it has survived a war. The engine may be completely finished. And you've probably walked past it hundreds of times without giving it a second thought. Perhaps you've even thought: “One of these days I'll send it to the scrap dealer.” Before you do that, stop. Because that old excavator might not be worth very m

An excavator doesn't have to be completely broken to be completely useless. One failed component can bring a 20-tonne machine worth hundreds of thousands — or even millions — of rand to a grinding halt. The frustrating part is that the component causing the problem may be relatively small. A failed sensor. A damaged hydraulic hose. A leaking cylinder. A faulty valve bank. A failed final drive. The machine doesn't care how much the rest of it is worth. If one critical componen

That old excavator sitting behind your workshop might be worth far more than you realise. The paint is faded. The tracks are worn out. The engine hasn't run in years. The cab looks like it has been through a war. And you've probably walked past it a hundred times thinking: “That's scrap.” Maybe it is. But maybe it isn't. Because when it comes to excavators, the value of the machine and the value of the parts are two very different things. A 20-tonne excavator that is no longe

Your excavator is still doing the job. Your parts supplier, however, has just told you: “Sorry, that part is obsolete.” For anyone running an excavator, those are words you really don't want to hear. The machine may be mechanically sound. The engine may have plenty of life left. The hydraulics may be working perfectly. The undercarriage may still have thousands of hours left in it. But one critical component fails — and suddenly a machine worth hundreds of thousands of rand i

Most people look at a written-off excavator and see one thing: scrap metal. At Vikfin, we see something entirely different. We see a machine with hundreds of valuable components that can be given a second life, helping contractors, mines, farmers, and plant hire companies keep their own excavators running at a fraction of the cost of buying new. An excavator may have reached the end of its working life, but that doesn't mean every part has. In fact, some of the most reliable

If an excavator cannot move, it is not a machine—it is just a very expensive piece of stationary steel. That’s where the travel motor comes in. The travel motor is the component that gives an excavator its mobility, allowing it to crawl across job sites, climb ramps, reposition itself, and handle tough terrain. It works hand-in-hand with the final drive to convert hydraulic power into controlled track movement. Despite being one of the hardest-working systems on the machine,

Demolition is one of the most punishing environments an excavator can face. Unlike standard earthmoving or mining operations where material is relatively consistent, demolition work throws everything at a machine—steel, reinforced concrete, dust, vibration, impact loads, and constantly changing working conditions. In short: demolition doesn’t just use an excavator, it abuses it. At Vikfin, we often see machines that look structurally fine but have internal components worn far

The swing bearing—also called the slew ring—is one of the most important and most expensive components on an excavator. It’s also one of the most overlooked. While operators tend to focus on engines, hydraulics, and undercarriage wear, the swing bearing quietly does its job day after day: allowing the entire upper structure of the excavator to rotate smoothly under massive loads. When it fails, it doesn’t fail quietly. It fails expensively. At Vikfin, swing bearing issues are

If there is one problem that quietly destroys excavators faster than most owners realize, it is overheating. An excavator that runs hot is not just inefficient—it is slowly killing itself. Engines, hydraulic pumps, seals, hoses, electronics, and even structural components are all affected when operating temperatures climb beyond safe limits. And in most cases, the root cause is not a catastrophic failure. It is a cooling system that is slowly losing efficiency. At Vikfin, we

If there is one component that quietly determines whether an excavator makes money or loses money, it is the hydraulic pump. Everything an excavator does—digging, lifting, swinging, travelling—depends on hydraulic pressure. And the hydraulic pump is what creates that pressure in the first place. When the pump is healthy, the machine feels powerful, responsive, and efficient. When it starts failing, everything slows down. Fuel consumption rises, performance drops, and eventual

Excavators used to be mostly mechanical and hydraulic machines. You had an engine, a pump, some valves, and a skilled operator who knew how to “feel” the machine. Those days are gone. Modern excavators are now highly computerized systems with sensors, ECUs, wiring harnesses, CAN bus networks, and electronic control modules managing almost every function—from fuel delivery to hydraulic pressure regulation. This evolution has improved efficiency, fuel consumption, diagnostics,

Hydraulic systems are the lifeblood of every excavator. Without hydraulics, your machine cannot lift, dig, swing, travel, or perform any of the tasks that make it productive. Yet many excavator owners and operators fail to recognize the early warning signs of hydraulic problems until the machine suffers a major breakdown. The truth is that hydraulic systems rarely fail overnight. In most cases, excavators provide numerous warning signs before a catastrophic failure occurs. Th

If the hydraulic pump is the heart of an excavator, then the hydraulic cylinders are the muscles. Every movement an excavator makes—lifting, digging, reaching, crowding, dumping, and even operating attachments—depends on hydraulic cylinders converting hydraulic pressure into mechanical force. Without them, your 20-ton excavator becomes little more than an expensive lawn ornament. Despite their seemingly simple design, hydraulic cylinders are among the hardest-working componen

If you strip an excavator down to its most essential functions, everything eventually comes back to one component. The hydraulic pump. It doesn’t swing the machine. It doesn’t dig the trench. It doesn’t move the boom directly. But it is the reason all of those things are even possible. Without a working hydraulic pump, an excavator becomes a very expensive piece of stationary steel. At Vikfin, we see hydraulic pumps more than almost any other high-value component failure. And

In the excavator world, everything eventually comes down to one thing: the engine. Hydraulics do the digging. Final drives move the machine. Swing motors rotate it. But none of it happens without a reliable engine sitting at the core of the machine, turning fuel into raw mechanical power. And here’s the hard truth most contractors learn the expensive way: Not all excavator engines are created equal. Some engines seem to run forever with basic maintenance. Others start giving

Most excavators don’t die dramatic deaths. They don’t explode on site. They don’t suddenly collapse in a spectacular failure. They don’t usually get taken out by one catastrophic event. Instead, they die slowly. Silently. And one of the biggest killers is something every contractor thinks they can live with: Dust and dirt. It sounds harmless. After all, excavators are built for construction sites, mines, quarries, and earthworks. Of course they’ll get dirty. But here’s the un
