Why the cheapest excavator part you can find may end up costing you far more than the expensive one. Let's talk about something that happens in the earthmoving industry every single day. An excavator breaks. A hydraulic pump dies. A final drive starts leaking. A swing motor gives up the ghost. An engine component fails. And suddenly the phone starts ringing. The owner wants a price. “What's the cheapest one you have?” Fair enough. Nobody likes paying more than they have to. B

If your excavator's final drive could talk, you'd probably want to listen. There is a moment every excavator owner knows. The machine is working. Everything seems normal. Then you notice something. A strange noise. A little vibration. The machine isn't travelling quite like it used to. One track seems slower. Maybe it pulls to one side. Maybe there's oil where there shouldn't be oil. Maybe the machine struggles on a slope. Maybe the final drive is making a noise that wasn't t

Sometimes the ugliest machine in the yard is the one making the most money. Walk into an earthmoving yard and you'll quickly notice something. Everybody loves shiny. The newer the excavator, the better. Fresh paint. Clean cab. Low hours. Fancy electronics. The latest model. The sort of machine that looks good parked outside the office while the owner explains to everyone how "this one is brand new." Nothing wrong with that. But here's an uncomfortable question: Does a new exc

The ugly, expensive, filthy bits that nobody thinks about until the excavator stops making money. Everyone talks about excavator engines. Hydraulic pumps. Tracks. Booms. Even final drives get their moment in the spotlight. But there is another category of excavator parts. The parts nobody wants to talk about. They aren't sexy. They don't make for impressive photographs. Nobody stands around the workshop admiring them. And yet, when one of them fails, your excavator can go fro

Because when your machine is down, you're not really buying a part. You're buying a solution. There is a moment every excavator owner knows. The machine stops. The operator phones. The workshop gets involved. Someone starts investigating. And eventually the dreaded sentence arrives: “We need a new part.” Now the procurement process begins. Phone calls. WhatsApps. Google searches. Emails. Photos. Part numbers. Prices. And inevitably, somebody says: “I've found one cheaper.” Co

The mechanic who has to fix it twice has a very different definition of “cheap.” Ask an experienced excavator mechanic what he thinks about cheap aftermarket parts and you might get a very predictable answer. Probably something along the lines of: “You get what you pay for.” But that doesn't quite capture it. Because experienced mechanics aren't necessarily against aftermarket parts. They understand that there are good aftermarket manufacturers, bad aftermarket manufacturers,

The uncomfortable question every owner eventually has to ask. There comes a moment in the life of every excavator when someone has to ask a very uncomfortable question: “Is this machine still worth fixing?” It's not an easy question. You've owned the machine for years. You know its quirks. Your operators know it. Your mechanics know it. You've already spent a small fortune keeping it alive. And every time something breaks, the temptation is to say: “Let's just fix this one.”

It's costing you money every minute it isn't working. An excavator breaks. The operator climbs out. The mechanic arrives. Someone starts making phone calls. A part needs to be found. A quotation needs to be approved. The supplier needs to locate it. The part needs to be paid for. It needs to be transported. The mechanic needs to fit it. The machine needs to be tested. And finally, hopefully, the excavator goes back to work. The natural question during all of this is: “How muc

It isn't buying an expensive part. It's buying the wrong one. There is a particular kind of phone call that nobody in the earthmoving industry enjoys receiving. It usually starts with: “We've fitted the part, but the machine isn't working properly.” Then comes the investigation. The part looks right. It bolts up. The machine starts. But something isn't quite right. Maybe the hydraulic function is wrong. Maybe the machine is pulling to one side. Maybe the travel speed isn't wh

An excavator rarely wakes up one morning and decides to completely destroy itself. More often, it gives you warnings. A strange noise. A little smoke. A hydraulic function that suddenly feels slower. A track that doesn't seem to have the power it used to have. A boom that creeps down when it shouldn't. A machine that starts running hotter than normal. The problem is that we often ignore these warnings. We tell ourselves: “It's an old machine.” Or: “It was just doing something

There is a point in every excavator's life when someone asks the question: “Is this machine still worth repairing?” It's a fair question. The machine is old. The paint is tired. The cab has seen better days. The hour meter has a number on it that makes the accountant nervous. And then something expensive fails. A final drive. A hydraulic pump. A slew motor. An engine. A valve bank. Suddenly someone says: “Maybe we should just replace the machine.” And sometimes, they're right

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

There is a dangerous sentence in the earthmoving industry: “We got it cheap.” Cheap is seductive. A bargain feels like a bargain. You find a 20-tonne excavator for R600,000 when similar machines are selling for R900,000. You feel pretty good about yourself. You have just saved R300,000. Or have you? Because there is a fundamental difference between: The price you pay for an excavator and The cost of owning that excavator. And if you don't understand the difference, that “chea

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

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

It looked like a bargain. The excavator was advertised at R500,000. The machine looked reasonably good. The seller was motivated. The buyer had been looking for a machine for weeks. So he bought it. Six months later, he had spent nearly another R500,000 keeping it alive. Suddenly, his R500,000 excavator had become a R1 million excavator. And here's the uncomfortable truth: It wasn't necessarily a bad purchase. The problem was that he had only calculated the purchase price. He

Most people look at an excavator and see one machine. Experienced operators and mechanics see something very different. They see a carefully engineered collection of thousands of individual components working together in perfect harmony. Every bucket lifted, every trench dug, and every tonne of earth moved depends on dozens of systems performing exactly as they should. When one component fails, the entire machine can grind to a halt. Understanding the anatomy of your excavato

Buying a used excavator can be one of the smartest investments you ever make. Or one of the most expensive mistakes. From a distance, two excavators may look almost identical. They could be the same brand, the same model, the same year, and even have similar hour meter readings. Yet one might deliver another 10,000 hours of reliable service, while the other could require hundreds of thousands of rand in repairs before it earns its first rand. The difference isn't what you see

Excavators are built to work in some of the toughest environments on Earth. They dig through rock. They load thousands of tonnes of material. They work in mud, dust, heat and rain. They spend their lives lifting, pulling, pushing and swinging enormous loads. It's no surprise that some components wear out faster than others. One of the biggest mistakes excavator owners make is waiting until a part fails completely before replacing it. By then, the damage has often spread to ne
