Your Excavator Is Worth Millions. Why Are You Saving R2,000 on the Part?
The cheapest part on the invoice can become the most expensive part in the yard.
Let's talk about something that happens every bloody day in the earthmoving industry.
A contractor has a machine worth R2 million.
Or R3 million.
Maybe R5 million.
It spends its life earning money by digging, loading, trenching, breaking, moving and shifting material.
The contractor watches fuel consumption.
He watches hours.
He negotiates finance rates.
He haggles over tyre prices.
He monitors productivity.
He knows exactly what the machine costs per hour.
Then something breaks.
He needs a part.
The supplier quotes R32,000 for the sensible option.
Another supplier has something for R30,000.
“I'll take the R30,000 one.”
Congratulations.
You've saved R2,000.
Now let's imagine that part fails three weeks later.
The excavator stops.
The mechanic gets called.
The machine needs to be stripped again.
The failed component needs to come out.
Another component needs to be sourced.
A truck needs to move.
Labour needs to be paid.
And the machine sits there for three days.
Suddenly your R2,000 saving has become a R100,000 problem.
Maybe more.
This isn't an argument that expensive parts are always better.
They're not.
It's an argument for something far more important:
Stop judging the cost of an excavator part in isolation.
The part isn't the cost.
The risk is part of the cost.
And so is the downtime.
Your excavator doesn't make money sitting in the yard
This seems obvious.
Yet it's amazing how often we forget it.
An excavator is not an investment-grade piece of garden furniture.
It is a production asset.
It makes money when it works.
It doesn't make money when it sits.
If your excavator is generating R5,000 of productive value per hour, then every hour of unnecessary downtime has a cost.
Five hours?
R25,000.
A working day?
R40,000 or more.
Two days?
R80,000+.
A week?
Now we're getting into serious money.
And that's before you include:
Mechanic's labour
Transport
Accommodation
Recovery
Lost crew productivity
Site delays
Penalties
Reprogramming
Subcontractor costs
Customer frustration
The R2,000 you saved on the part suddenly looks rather fucking insignificant.
The excavator is expensive.
The downtime is worse.
Let's take a hypothetical example.
You have a 22-tonne excavator.
The machine is worth R2.5 million.
It is working on a civil construction project.
Let's assume its productive value is R6,000 per hour.
The hydraulic pump starts failing.
You have two options.
Option A
A component costs:
R80,000
Option B
A cheaper alternative costs:
R70,000
You save:
R10,000
Fantastic.
Except nobody should make the decision by looking only at those two numbers.
Suppose Option B has a significantly higher risk of failure.
If it fails and causes three days of downtime:
3 days × 8 hours × R6,000
That's:
R144,000 in lost productive capacity.
Add another R20,000 in labour, transport and associated costs.
You're now at:
R164,000.
Your R10,000 saving has potentially cost you R164,000.
That's not cheap.
That's fucking expensive.
But here's the important bit
We are not saying:
“Always buy the most expensive part.”
That would be nonsense.
A R150,000 OEM component isn't automatically better value than a R90,000 quality alternative.
Nor is a brand-new part automatically better than a properly inspected used OEM component.
Nor is an aftermarket component automatically rubbish because it isn't made by the original manufacturer.
There are good alternatives.
There are excellent used OEM components.
There are quality aftermarket manufacturers.
There are refurbished components that make excellent economic sense.
And there are expensive parts that aren't worth buying for a particular machine.
The question is not:
“Which part is the most expensive?”
The question is:
“Which solution gives me the best combination of cost, reliability and downtime risk?”
That's a very different question.
Price is easy to compare.
Risk isn't.
This is one of the reasons cheap parts are so seductive.
The price is sitting there in black and white.
R30,000.
R32,000.
R35,000.
Easy.
Risk is more difficult.
You can't see it.
You can't put it neatly on the quote.
You can't photograph it.
You can't tell your accountant:
“This component has a 14% greater chance of ruining my month.”
But risk is real.
And experienced contractors understand this.
They've been burned before.
They've bought the cheap component.
They've fitted it.
They've watched it fail.
And they've had to pay for the same job twice.
That's when the lesson becomes permanent.
The cheapest part can be the part you pay for twice
Let's say you need a hydraulic cylinder.
Supplier A:
R45,000
Supplier B:
R40,000
You choose B.
It looks like a saving.
Then the cylinder fails.
You now have to:
Stop the machine.
Call the mechanic.
Remove the cylinder.
Transport it.
Diagnose the failure.
Source another cylinder.
Transport the replacement.
Install it.
Test the machine.
Put the machine back into production.
You haven't saved R5,000.
You've potentially bought the same job twice.
And the second time, you're doing it while the machine is supposed to be earning money.
Labour doesn't become free because the part was cheap
This is another bit of mental accounting that drives me mad.
People obsess over the price of the component.
But sometimes the component is only a fraction of the total repair cost.
Imagine replacing a final drive.
The part costs R50,000.
The mechanic charges R12,000.
Transport costs R5,000.
Miscellaneous costs add another R3,000.
You're already at:
R70,000.
Now imagine the cheap final drive fails.
You have to do the labour again.
Transport again.
Testing again.
Downtime again.
Suddenly your R5,000 saving on the part has cost you another R20,000–R50,000.
And that's assuming nothing else was damaged.
The machine utilisation number matters more than the part price
This is the number contractors should obsess over.
Utilisation.
How many hours is the machine actually working?
How much revenue or productive value does it generate per hour?
How much does it cost when it isn't working?
Because once you understand those numbers, the parts decision becomes much clearer.
Imagine two contractors.
Contractor A buys a component for R40,000.
Contractor B buys one for R50,000.
Contractor A feels like he won.
Until Contractor A's machine spends four extra days parked because of a component problem.
Contractor B's machine keeps working.
Who actually spent less?
The invoice doesn't tell you.
The machine does.
Downtime is a hidden tax
Nobody sends you a bill saying:
“Congratulations. Your machine was parked for 37 hours. Please pay R185,000.”
But that's effectively what happens.
The cost simply appears somewhere else.
The excavator doesn't produce.
The operator sits idle.
The project falls behind.
Another machine has to be hired.
The contractor works overtime.
The client starts asking questions.
The programme moves.
The transport company gets called.
The mechanic gets called again.
And the owner starts drinking more coffee.
Possibly more whisky.
The downtime bill is very real.
It's just disguised as ten different expenses.
The R2,000 question
So let's come back to the original question.
Your excavator is worth millions. Why are you saving R2,000 on the part?
If you've properly evaluated the alternatives and determined that the R2,000 cheaper part has the same quality, compatibility, expected service life and support, then by all means:
Save the R2,000.
That's good business.
But if the R2,000 saving means accepting a substantially higher risk of failure, then you're not saving R2,000.
You're gambling R2,000 against the entire economics of the machine.
And those are very different things.
Cheap isn't the same as bad
Let's make this absolutely clear.
At Vikfin, we sell used OEM and refurbished OEM excavator components.
That means we're not sitting here telling you that the only sensible solution is to buy brand-new OEM parts from the manufacturer.
Sometimes that is exactly what makes sense.
Sometimes it isn't.
A good used OEM component can be an excellent solution.
A properly refurbished OEM component can be an excellent solution.
A reputable aftermarket component can be an excellent solution.
The right answer depends on:
The machine
The component
The application
The condition
The supplier
The warranty
The availability
The cost
The consequences of failure
That's why blanket statements like “OEM is always better” or “aftermarket is always cheaper” don't help much.
You need to evaluate the actual job.
There's a difference between cheap and good value
This is probably the most important distinction in the entire article.
Cheap is a price.
Value is a relationship between price, performance, reliability and risk.
A R20,000 component that lasts six months might be terrible value.
A R35,000 component that gives you several years of reliable service might be excellent value.
A R50,000 component that arrives tomorrow might be better value than a R40,000 component that takes three weeks.
Why?
Because the machine might be losing R10,000 every day while you're waiting.
The cheapest part isn't necessarily the cheapest solution.
The cost of waiting can be even bigger
Let's say you have two suppliers.
Supplier A:
R40,000
Delivery:
10 days
Supplier B:
R47,000
Delivery:
Tomorrow
You save R7,000 by choosing Supplier A.
But if the excavator is worth R50,000 a day in productive output, you've potentially sacrificed R450,000 of productive capacity to save R7,000.
Again, this doesn't mean Supplier B automatically wins.
Maybe the machine can continue working.
Maybe you have another excavator available.
Maybe the repair isn't urgent.
Maybe the cheaper supplier has a better component.
The point is:
Price cannot be evaluated without context.
This is why good parts suppliers ask questions
A good supplier shouldn't simply hear:
“I need a pump.”
and respond:
“Here's the price.”
There should be questions.
What machine?
What serial number?
What part number?
What's the problem?
Has the component been diagnosed?
What is currently fitted?
What application is the machine working in?
How quickly do you need it?
What alternatives are acceptable?
Those questions aren't bureaucracy.
They're risk management.
The goal is to avoid selling you something that doesn't solve the problem.
Because if we sell you the wrong part, we've got another problem.
And so do you.
Don't forget the cost of fitting the wrong part
Here's another little gem.
A part can be technically "correct" for the model but still be wrong for the machine.
This is particularly relevant when dealing with machines that have different configurations or production ranges.
That's why we keep banging on about serial numbers.
CAT 320 isn't necessarily enough.
Komatsu PC210 isn't necessarily enough.
Hitachi ZX210 isn't necessarily enough.
Doosan DX225 isn't necessarily enough.
The machine's serial number, existing component and configuration can be critical.
Because fitting the wrong part is one of the most expensive forms of quality control known to mankind.
Your mechanic's time isn't free
A good earthmoving mechanic is a valuable asset.
You don't want him spending half a day removing a component only to discover that the replacement doesn't fit.
Then another half day reinstalling the original.
Then another day waiting for the correct component.
And then another installation.
That's not just annoying.
That's expensive.
And the mechanic could have been fixing another machine.
So when you evaluate a component, remember:
You're not only buying the component.
You're buying the installation process.
And the opportunity cost of that labour.
The cheapest part is often the most expensive when it fails
This is where the argument becomes brutally simple.
Imagine the part costs R30,000.
Installation costs R15,000.
Transport and associated costs are R5,000.
Total repair:
R50,000.
The machine then works.
Fantastic.
But if the component fails and you repeat the repair, your total isn't R30,000 anymore.
It's potentially:
R30,000 + R15,000 + R5,000
again.
That's another:
R50,000.
Now you've spent R100,000.
And you haven't bought another hour of productive capacity.
You've simply returned to where you were supposed to be in the first place.
The machine doesn't care what you paid for the part
This is perhaps the simplest way to think about it.
Your excavator doesn't know whether the component cost R20,000 or R80,000.
It doesn't care.
It doesn't reward you for negotiating the best discount.
It doesn't give you a gold star for saving R2,000.
It has one job:
Work.
Dig.
Load.
Move.
Break.
Repeat.
The economic value of the machine comes from utilisation.
So the parts decision should ultimately support utilisation.
What should you actually do?
Before buying a cheap component, ask five questions.
1. Is it definitely the correct part?
Don't rely on appearance.
Confirm the machine.
Serial number.
Part number.
Configuration.
2. Who made it?
Know the manufacturer.
Know the source.
Know what you're actually buying.
3. What happens if it fails?
This is the question almost nobody asks.
How long will you be down?
Can you get another one quickly?
Is there a warranty?
Who pays for the labour?
4. What is the cost of installation?
If the component is difficult or expensive to install, reliability becomes even more important.
5. How much does the machine cost me per hour when it's standing?
This number changes the entire conversation.
The real equation
Forget:
Part price = cost.
Think:
Total Cost = Part + Labour + Transport + Downtime + Failure Risk
That's a much more useful equation.
And suddenly a R2,000 difference between two parts doesn't look nearly as important.
Sometimes the cheaper part will still win.
Sometimes the more expensive one will.
Sometimes a used OEM component will make the most sense.
Sometimes refurbished OEM.
Sometimes aftermarket.
Sometimes new OEM.
The answer isn't predetermined.
The answer comes from understanding the machine and the risk.
At Vikfin, we're interested in the economics
We're not interested in selling you the most expensive component we can find.
That's a shitty business model.
We're interested in finding a sensible solution.
If a good used OEM component will do the job, that's worth discussing.
If a refurbished component makes more economic sense, let's look at it.
If a new component is the right answer, we'll tell you.
If we think the diagnosis is questionable, we'll ask questions.
Because the objective isn't:
“Sell Ralph another part.”
The objective is:
“Get the customer's machine working without making him financially suicidal.”
That's a much better long-term business strategy.
Your excavator is a production asset
Remember what you're actually sitting on.
That machine might be worth R2 million.
R3 million.
R5 million.
But its real value to you isn't just what someone would pay for it tomorrow.
Its value is the income it can generate while it's working.
That's why utilisation matters.
That's why maintenance matters.
That's why diagnostics matter.
And that's why parts selection matters.
You can save R2,000 on a component and lose R200,000 in productive capacity.
Or you can spend R2,000 more and eliminate a significant amount of risk.
Neither decision is automatically correct.
But ignoring the risk because the number on the invoice is smaller is not cost control.
It's simply cheapness wearing a tie.
So the next time you're comparing two parts...
Don't just ask:
“Which one is cheaper?”
Ask:
“Which one gives me the best chance of keeping this machine working at the lowest sensible total cost?”
That's the question that matters.
Because when you've got a R3 million excavator earning money for you, arguing over R2,000 while ignoring downtime is like buying a Ferrari and then refusing to spend R500 on petrol.
The saving is real.
The logic is fucking insane.
Your excavator doesn't need the cheapest part.
It needs the right part at the right price with the right level of risk.
And that's exactly where a good excavator-parts supplier earns his money.
