“It doesn't run.”
Those four words can either be the beginning of a fantastic excavator deal...
...or the beginning of a very expensive mistake.
Non-running excavators are everywhere.
Machines with blown engines.
Machines with failed hydraulic pumps.
Machines that have been sitting in a yard for five years.
Machines damaged in accidents.
Machines that were simply parked when the owner decided that the repair wasn't worth the money.
And because they don't run, they can sometimes be bought for a fraction of the price of a working excavator.
That's the attraction.
A 20-tonne excavator worth R1 million when operational might be available as a non-runner for R300,000.
Sounds like a bargain.
But there's a catch.
You haven't bought a R1 million excavator for R300,000.
You've bought a R300,000 problem.
The question is whether that problem is worth solving.
And that's where the numbers get interesting.
What Exactly Is a Non-Runner?
The first mistake people make is treating every non-runner as the same.
They're not.
There is a massive difference between:
“The engine won't start.”
and:
“The machine is mechanically destroyed.”
A non-runner could have:
A flat battery.
A faulty starter.
A wiring problem.
A fuel-system problem.
A seized engine.
A failed ECU.
A hydraulic pump failure.
A damaged final drive.
A failed electrical system.
A major accident.
Severe structural damage.
Multiple major component failures.
The machine doesn't tell you which one it is simply by refusing to start.
Diagnosis comes first.
The Most Important Question: Why Doesn't It Run?
Before buying a non-runner, this is the question you should obsess over.
Not:
“How cheap is it?”
But:
“Why doesn't it run?”
If the answer is:
“It needs a battery.”
Fantastic.
If the answer is:
“The starter motor is faulty.”
Potentially straightforward.
If the answer is:
“The engine seized three years ago and nobody knows why.”
Now you're entering a different universe.
And if the answer is:
“It hasn't run for five years, the wiring is damaged, the hydraulics are contaminated and the machine was involved in an accident.”
You may not have bought a bargain.
You may have bought a donor machine.
And that isn't necessarily a bad thing either.
Step One: Establish the Machine's Value When Running
Before you even consider the repair, establish what the machine would be worth if it were operational.
Let's say a working version of the excavator is worth:
R1,000,000
The non-runner costs:
R300,000
At first glance, you've got:
R700,000 of potential upside.
But that R700,000 isn't profit.
You still need to pay for:
Transport
Diagnosis
Repairs
Parts
Labour
Fluids
Testing
Unexpected failures
Downtime
And there is always something unexpected.
Step Two: Work Out the Worst-Case Scenario
This is where experienced buyers think differently.
Don't ask:
“What will it cost if everything goes well?”
Ask:
“What will it cost if everything goes wrong?”
Suppose the engine is seized.
You budget:
R150,000 for an engine repair.
Sounds reasonable.
Then you discover:
Turbocharger damaged.
Radiator damaged.
Hydraulic pump contaminated.
Wiring harness damaged.
Starter destroyed.
Suddenly your R150,000 repair has become R400,000.
This is why a non-runner should always be bought with a contingency budget.
Step Three: Inspect the Engine
If the engine doesn't run, you need to establish as much as possible about its condition.
Check:
Oil level.
Coolant level.
Oil condition.
Coolant condition.
Signs of contamination.
Evidence of overheating.
External leaks.
Corrosion.
Turbocharger condition.
Crankshaft movement.
Signs of seizure.
Evidence of previous repairs.
If possible, establish whether the engine turns over.
If it doesn't, that's obviously a significant warning.
But even a seized engine doesn't necessarily kill the deal.
Why?
Because engines can be replaced.
The Used Engine Option
This is one of the reasons the used excavator parts market changes the economics of non-runners.
Suppose the original engine is beyond economic repair.
You don't necessarily have to scrap the excavator.
You may be able to find:
A good used OEM engine.
If the machine is otherwise healthy, replacing the engine may be significantly cheaper than buying another excavator.
This is particularly attractive when the machine itself is worth substantially more operational than non-operational.
Step Four: Inspect the Hydraulics
This is where things can get very expensive.
Look carefully at:
Hydraulic pump.
Valve bank.
Hydraulic cylinders.
Hoses.
Hydraulic tank.
Hydraulic oil.
Hydraulic motors.
Final drives.
Slew motor.
If the engine has failed catastrophically, find out whether the hydraulic system was affected.
Metal contamination from a failed component can travel through a hydraulic system and cause secondary damage.
That can turn a simple repair into a major hydraulic rebuild.
Step Five: Check the Final Drives
A non-runner may have excellent final drives.
Or it may have two dead final drives.
You need to know.
Inspect for:
Oil leaks.
Damage.
Abnormal play.
Cracks.
Missing components.
Evidence of previous failure.
If the machine can't move, it may be impossible to fully test the drives.
That's another risk.
And if you can't test something, price the machine accordingly.
Step Six: Inspect the Slew System
The same applies to the slew system.
Check:
Slew motor.
Slew gearbox.
Slew bearing.
Excessive play.
Oil leakage.
Structural damage.
A damaged slew bearing can be an extremely expensive repair.
A good slew system can be a major positive.
Step Seven: Look at the Undercarriage
This is one of the easiest areas to overlook.
A non-runner may have been sitting for years.
The tracks might look fine.
But look carefully.
Check:
Track chains.
Shoes.
Rollers.
Idlers.
Sprockets.
Track adjusters.
If the machine needs a complete undercarriage, you may be facing a substantial additional cost.
And remember:
A machine can have a perfect engine and still be uneconomical if the undercarriage is finished.
Step Eight: Inspect the Structure
This is absolutely critical.
Look for:
Cracks.
Weld repairs.
Boom damage.
Dipper damage.
Chassis cracks.
Counterweight damage.
Track-frame damage.
Signs of accident damage.
Structural repairs can be expensive.
And some damage may not be immediately obvious.
A machine that has been rolled or badly abused needs particularly careful inspection.
Step Nine: Check the Hours
Don't automatically believe the hour meter.
Look at the machine itself.
Does the condition correspond with the claimed hours?
Check:
Pedals.
Joysticks.
Seat.
Controls.
Tracks.
Pins and bushes.
Hydraulic cylinders.
Cab condition.
If the machine allegedly has 5,000 hours but looks like it has done 20,000, ask questions.
Hours aren't everything.
But they are useful information.
Step Ten: Find Out Why It Was Parked
This might be the most revealing question of all.
Ask the previous owner:
“Why did you stop using it?”
Was it:
Engine failure?
Hydraulic failure?
Accident?
Parts availability?
Lack of work?
Financial problems?
Age?
Operator damage?
If the owner stopped using the machine because a R300,000 repair was required, that tells you something.
If they stopped using it because they simply bought a newer excavator, that's a completely different story.
The reason it was parked matters.
The Non-Runner Calculation
Let's say you find a 20-tonne excavator.
Purchase price
R300,000
Transport
R30,000
Engine replacement
R150,000
Hydraulic repairs
R80,000
Undercarriage work
R100,000
Electrical repairs
R40,000
Miscellaneous
R50,000
Total investment
R750,000
If the machine is worth R1 million once operational, you've potentially created R250,000 of value.
Not bad.
But now suppose the hydraulic pump also needs replacing.
Add R120,000.
You're now at:
R870,000.
And suddenly your margin is getting very thin.
This is why non-runner purchases live or die on accurate diagnosis.
The R300,000 Non-Runner Isn't Necessarily a R300,000 Deal
One of the biggest psychological traps is focusing on the purchase price.
You see:
R300,000
and compare it with:
R1,000,000
Your brain immediately sees:
R700,000 profit.
But that isn't how machinery works.
Your real calculation is:
Purchase price + transport + repairs + refurbishment + downtime + finance + unexpected costs
versus:
Value of the completed machine
That's the calculation.
The Hidden Advantage: You Can Buy Parts From Yourself
This is where things get particularly interesting if you're in the excavator parts business.
A non-runner that is uneconomic to repair as a complete machine may still have enormous value as a donor machine.
Imagine the machine needs:
Engine: R200,000
Hydraulic pump: R150,000
Undercarriage: R150,000
Electrical repairs: R80,000
Repairing it doesn't make sense.
But perhaps the machine still has:
Good final drives.
Good slew motor.
Good valve bank.
Good hydraulic cylinders.
Good bucket.
Good counterweight.
Good cooling pack.
Good tracks.
Good cab components.
Suddenly the machine may be worth more in parts than as a repaired excavator.
This is the exact opposite calculation.
Repair It or Dismantle It?
This is the central question.
There are essentially two ways to value a non-runner.
Value as a machine
What is it worth if repaired and operational?
Value as a collection of components
What are all the usable parts worth?
Whichever number produces the better economic outcome should influence your decision.
And sometimes that means:
Don't repair the excavator.
Dismantle it.
The Donor Machine Strategy
This is a strategy that can work particularly well for contractors or plant owners who operate multiple machines of the same model.
Imagine you have:
Five identical excavators.
One suffers catastrophic engine failure.
Instead of spending R300,000 repairing it, you could potentially buy another damaged machine of the same model and use it as a source of spare components.
You now have:
Four working machines + one donor machine.
That donor machine may provide:
Final drives
Slew motor
Valve bank
Hydraulic cylinders
Electrical components
Cooling components
Cab components
Pins and bushes
Other critical spares
It effectively becomes a parts bank.
For a large fleet, that can be extremely valuable.
The Parts Value of a Non-Runner
This is where you need to think like a dismantler.
Imagine the following theoretical values:
Component | Potential Value |
Engine | R150,000 |
Final drives | R80,000 |
Slew motor | R50,000 |
Valve bank | R60,000 |
Hydraulic cylinders | R60,000 |
Tracks | R40,000 |
Cooling pack | R25,000 |
Bucket | R25,000 |
Counterweight | R20,000 |
Electrical components | R20,000 |
Other components | R40,000 |
That's potentially:
R570,000 of component value.
And the complete machine may only have been worth R300,000 as a non-runner.
This is why dismantlers look at machines differently.
We're not necessarily buying an excavator.
We're buying inventory.
But Don't Overvalue the Parts
There is an important warning here.
Just because a component is worth R100,000 in theory doesn't mean you'll automatically sell it for R100,000.
You need:
Demand.
Condition.
Correct model.
Storage.
Marketing.
Customers.
Time.
Refurbishment.
Testing.
Transport.
A warehouse full of obscure components isn't necessarily a successful business.
Inventory only has value if somebody wants it.
That's why experience in the parts market matters.
Popular Machines Are Better Donor Machines
If you're considering buying a non-runner specifically for dismantling, look for machines with a large installed base.
A popular excavator model potentially gives you:
More customers.
More parts demand.
More interchangeability.
Better component liquidity.
A rare machine might have valuable components.
But finding the buyer can be difficult.
A common 20-tonne excavator can have a much larger potential market.
Beware of the “Everything Is Good” Seller
When buying a non-runner, be cautious of descriptions like:
“Engine just needs a little work.”
“Hydraulics are probably fine.”
“It was running perfectly before it stopped.”
“It only needs electrical attention.”
Maybe.
But maybe not.
Treat every untested major component as unknown condition.
And price accordingly.
A non-runner should not be priced as though everything works.
The Best Time to Inspect Is Before You Buy
This sounds obvious.
But it's amazing how often people buy non-runners based on photographs and a seller's description.
If possible, send a mechanic.
Inspect the machine.
Take photographs.
Check the oil.
Check the coolant.
Look for contamination.
Inspect the cylinders.
Inspect the undercarriage.
Check for structural damage.
Look at the hydraulic pump.
Look at the final drives.
Check the wiring.
Find the machine serial number.
And get as much history as possible.
A few thousand rand spent on inspection can potentially save hundreds of thousands later.
Don't Forget Transport
Non-runners have another hidden cost.
They don't drive onto the lowbed.
You need to move them.
Depending on the machine and location, transport can become expensive.
You may need:
Crane assistance.
Recovery equipment.
Specialised lowbed transport.
Loading equipment.
Factor this into your purchase price.
A non-runner 500 km away isn't necessarily cheaper than a more expensive one sitting down the road.
The Same Machine Can Have Two Completely Different Values
This is the fascinating part.
Imagine an excavator worth:
R1 million operational.
As a non-runner:
R300,000.
As scrap:
R100,000.
As a collection of usable parts:
Potentially R500,000+, depending on condition and demand.
Three completely different valuations.
Same machine.
Different perspectives.
The contractor sees:
A repair project.
The scrap dealer sees:
Metal.
The dismantler sees:
Inventory.
And the clever buyer knows which valuation is relevant to him.
So, Is Buying a Non-Runner a Genius Move?
Sometimes.
A non-runner can be an exceptional investment if:
The machine is fundamentally sound.
The problem is clearly identified.
Parts are available.
Repair costs are predictable.
The machine has strong residual value.
You have access to good mechanics.
You understand the model.
You have a contingency budget.
In that situation, you can potentially buy a machine below market value, refurbish it and create significant value.
Or Is It a Money Pit?
Also sometimes.
Walk away if:
The cause of failure is unknown.
Multiple major systems are damaged.
The structure is badly compromised.
Parts are obsolete.
The undercarriage is finished.
The machine has been badly abused.
Repair costs are impossible to estimate.
The total investment approaches replacement value.
And especially if:
You are relying on everything going perfectly.
It won't.
The Vikfin Way of Looking at a Non-Runner
At Vikfin, we've developed a slightly different perspective.
When we look at a non-running excavator, we don't ask only:
“Can we make this machine run?”
We ask:
“What is this machine worth?”
And that means looking at:
The machine value
What is it worth operational?
The repair value
What would it cost to make operational?
The parts value
What are the individual components worth?
The scrap value
What is the absolute floor value?
Then we compare them.
That gives us a much clearer picture of what we're actually buying.
Sometimes the Best Non-Runner Is the One You Don't Repair
This sounds counterintuitive.
But it's true.
If you buy a machine for R250,000 and discover that it needs R600,000 of repairs, don't automatically assume you've made a terrible purchase.
Perhaps the machine has:
A good final drive.
Good slew motor.
Good valve bank.
Good cylinders.
Good tracks.
Good cooling system.
Good bucket.
Good structural components.
Maybe those components are worth R450,000 collectively.
Suddenly, the machine may still have been a good purchase.
You just shouldn't rebuild it.
A Non-Runner Is a Question, Not an Answer
That's probably the best way to think about these machines.
A non-runner isn't automatically:
A bargain.
And it isn't automatically:
A disaster.
It's a question.
What is wrong with it?
What will it cost to fix?
What will it be worth when fixed?
What are the parts worth?
What are the risks?
Once you've answered those questions, the decision becomes much easier.
Before You Buy That Non-Runner...
Ask yourself:
1. Why doesn't it run?
Get a specific answer.
2. What is it worth when operational?
Establish the real market value.
3. What will it cost to repair?
Get realistic estimates.
4. What could go wrong?
Build a contingency.
5. Are parts available?
Especially for major components.
6. What's the condition of the undercarriage?
Don't overlook it.
7. What's the condition of the structure?
Look for cracks and accident damage.
8. What are the major components worth individually?
Calculate the parts value.
9. How much will transport cost?
Especially if it's a non-runner.
10. What's your exit strategy?
Repair and operate?
Repair and sell?
Or dismantle and sell the components?
Know the answer before you buy.
And That's Where Vikfin Can Help
Vikfin buys non-running and used excavators specifically because we understand that a machine can have value even when it doesn't run.
We dismantle excavators and recover usable OEM components.
Final drives.
Slew motors.
Valve banks.
Engines.
Hydraulic cylinders.
Tracks.
Cooling packs.
Wiring harnesses.
Buckets.
Quick couplers.
Counterweights.
And many other components.
We then inspect, refurbish where appropriate and sell those components to customers who need them.
So if you've got a non-runner sitting in your yard, don't automatically think:
“Scrap.”
And don't automatically think:
“Repair.”
Think:
“What is this machine really worth?”
Because sometimes the answer is a working excavator.
Sometimes it's a parts machine.
And sometimes...
it's both.
