Excavator Engine FAQ
Excavators are one of the most powerful construction machines on earth. They can complete complex and heavy tasks with ease – assuming that the machine is in good condition.
They can complete such heavy and complex tasks because of their powerhouse – the engine.
In this guide, you will learn all about excavator engines. You are going to learn about:
- How excavator engines work
- How much horsepower they have and how much fuel they consume
- How to service your excavator engine
- How to maintain your excavator engine
Keep reading this guide to find out more.
1. How Does An Excavator Engine Work?
Your excavator engine is the powerhouse of your excavator. Your excavator cannot do anything without its engine. When you power up your excavator engine, it drives its power to three hydraulic pumps.
The two primary pumps supply oil under high pressure to the swing motor, track motor, and other excavator accessories. The third hydraulic pump has a lower amount of pressure compared to the first two.
The third pump helps the machine’s operator operate the machine without a lot of struggle.
It is, therefore, important to always keep your excavator engine in good condition because it is one of the key components of an excavator.
2. How Much Horsepower Does An Excavator Engine Have?
Now, you need to understand first that there are different types of excavators. There are three categories of these excavators:
- Mini excavators – this type of excavator does not weigh more than seven metric tons.
- Standard excavators – this type of excavator does not weigh less than seven metric tons. They also do not weigh more than 45 metric tons.
- Large excavators – This type of excavator weighs more than 45 metric tons. They are ideal for super heavy tasks.
Check this out:
Mini excavator engines provide your excavator with around 95 to 120 horsepower. They are ideal for light tasks. Standard excavator engines provide your excavator with approximately 150 to 275 horsepower.
As for large excavators, which weigh more than 45 metric tons, its engine will provide your excavator with around 370 to 535 horsepower.
Remember:
The bigger the excavator engine, the more fuel it consumes.
3. Which Fuel Does An Excavator Engine Use?
Diesel is the most common type of fuel used in excavators and other heavy machinery. Diesel is used in excavators because it provides more torque to drive the excavator and enables it to complete its tasks effectively and efficiently.
Diesel is also heavier than gasoline. This means that diesel is way more efficient than gasoline – it does not consume a lot of fuel to complete a given task. Fuel efficiency helps you save a lot of money.
Bottom line:
Diesel fuel is preferred over gasoline as it provides more torque and it is more efficient.
4. How Much Fuel Does An Excavator Use Per Hour?
Now, different types, models, and makes of excavators consume different amounts of fuel. It’s impossible to state the exact amount of fuel an excavator will consume per hour.
Check this out:
You can calculate the amount of fuel your excavator can consume per hour. It’s not a complicated process. You’ll only need to know the amount of fuel your excavator can hold in its fuel tank (gallons or liters) and then divide that value by the number of hours your excavator has worked.
In other words:
Suppose your excavator has a capacity of 108 gallons (410 liters), and the machine has worked for ten hours; the fuel consumption of your excavator is 108 gallons by 10 hours or 10.8 gallons per hour.
You can also calculate excavator fuel consumption by using a notebook. You can draw a grid on the notebook with headings. The headings can include the date, start engine time, end engine time, excavator operator name, the total amount of hours worked, fuel used, and fuel consumption.
You’ll then need to keep a keen eye on the results every time you use your excavator. If the results vary with more than what is normal, consider asking yourself the following questions:
- Was the excavator performing heavier tasks than usual?
- If you have more than one excavator operator, does he/she consume a lot of fuel than others? If so, the said operator probably needs more training.
5. What Are The Components Of An Excavator Engine?
Different excavators have different engines, but they all serve the same purpose – the excavator’s powerhouse. They all burn diesel fuel to power the excavator.
Now, here are the common items that you’ll find on all excavator engines. They are the primary parts:
Pistons, bearings, turbochargers, cylinder block, valve seat, valve springs, fuel pump, fans, intake manifold, exhaust valves, and injectors.
Most engine parts move mechanically.
You’ll need to maintain your engine so that it may remain strong and last for long. Keep reading this guide to understand how to know when your excavator engine parts are damaged, how to diagnose the problem, and the most appropriate measure to take when damages occur.

6. What Are The Common Excavator Engine Problems?
It’s true that:
Excavator engines, over time, start having problems. It is due to the constant minimal wearing out of parts. Now, there are some commonly found problems that all excavator engines must face after being in service for some time.
Check this out:
The first common problem across all excavator engine problems is the constant increase in engine noise. You’ll feel as if your excavator’s body is vibrating, and the throttle has a boom. The reason why this issue occurs is probably that the bottom engine guard plate is broken.
If the bottom engine guard plate is broken or damaged, your excavator engine’s oil pan will most likely be denied. The guard plate protects the engine from denting, and therefore it prevents denting your excavator engine oil pan.
Once you accelerate, the guard plate will contact the oil pan, and therefore it will produce a lot of noise. The best way to resolve this issue is to remove the bottom engine guard from your excavator and straighten it.
The second common issue is when your excavator engine consumes a lot of oil. This unexpected and rapid engine oil consumption is simply because the engine oil enters your engine’s combustion chambers.
Engine oil enters your engine’s combustion chambers because of excessive oil pressure. It could also be because of the wear of your engine’s components. As the engine ages, so do its valves and seals – they jam.
The third common problem excavator engines must face in their service life is that there are times your engine’s power is insufficient. Apart from engine power being insufficient, the excavator produces a lot of black smoke.
This type of problem occurs because there is no proper internal combustion, thus producing little power and black smoke. Black smoke is a sign of improper combustion in the internal combustion chambers.
Your excavator engine is weak, and it fails to supply enough pressurized oil to the three main pumps.
The final common problem is that your excavator engine fails to start. In addition to that, even when the excavator engine starts, it has a strong feeling of shock. This shock is most felt when the excavator is at a low speed.
A faulty spark plug mostly causes this problem. Another cause for this problem is that your excavator ignites too fast.
You’ll need to ensure that your spark plugs are in good shape – preferably serviced before achieving 30,000 km.
Whenever your excavator engine faces an abnormal issue, you should stop it immediately. You should then have it checked out by a professional to prevent further damages to the excavator engine’s components.
7. How Much Power Does An Excavator Engine Produce?
Your excavator’s engine power depends on the type of excavator. Remember that there are three categories of excavators:
- Mini excavators – this type of excavator does not weigh more than seven metric tons.
- Standard excavators – this type of excavator does not weigh less than seven metric tons. They also do not weigh more than 45 metric tons.
- Large excavators – This type of excavator weighs more than 45 metric tons. They are ideal for super heavy tasks.
Now, depending on the category which your excavator falls into, the amount of horsepower its engine produces varies.
8. After How Long Should I Service My Excavator Engine?
Servicing your excavator engine varies, depending on your excavator’s make, model, and performance. As such, it is important to refer to your excavator’s users’ manual or contact a professional and reputable company to help know when you’ll need to service your engine.
However, that’s not all:
When servicing your excavator engine, there are components that you’ll need to check on:
- The type of engine oil you use matters a lot. Consider changing your oil when servicing your excavator engine. Now, changing your excavator engine oil is not a complex process – you can do it yourself. You’ll also need to change your gearbox’s oil.
- You’ll need to replace your crankcase filter with a new one. The reason why it is imperative to change your crankcase filter is that excavator engines use diesel. When diesel burns, it produces diesel vapor. The crankcase filter filters this vapor. Remember to check your manual to know when to change your crankcase filter.
- You’ll yet again need to replace your excavator engine’s air filter. Replacing their air filter helps keep airflow in the engine good and increases your turbocharger’s service life, effectiveness, and efficiency.
- Adjust your valves, preferably after every 2,000 hours of operating hours. You can acquire these valves from a professional company.
Here’s the deal:
You need to know the exact time when you’ll need to service your excavator’s engine. This information will benefit you by ensuring that your excavator serves you effectively, efficiently, and long.
Check out this summarized table that shows what you need to change after a given duration:
Number of Operating Hours | Items to Replace on Excavator Engines |
500 operating hours | – Hydraulic filter
– Fuel Filter – Change Engine Oil |
1000 operating hours | – Hydraulic Filter
– Air Filter (Internal) – Air Filter (External) – Fuel Filter – Engine Oil – Gearbox Oil – Valve Cover Adjustment |
1500 operating hours | – Engine Oil
– Fuel Filter |
2000 operating hours | – Hydraulic Filter
– Air Filter (Internal) – Air Filter (External) – Fuel Filter – Engine Oil – Gearbox Oil – Valve Cover Adjustment |
You can always contact us for more information on when you can service your excavator engine.
9. What Is The Optimum Engine Oil Level For Excavators?
Now, it’s imperative to check the level of your excavator engine oil constantly. It is an easy task – you can do it yourself. Its importance cannot be emphasized further, as it helps you maintain your engine. You need to perform it daily to check the level of oil in your excavator engine.
You can check your excavator engine oil level by using the engine oil dipstick.
The best time to check your excavator engine oil level is before you begin operating your excavator. Take your engine oil level when the excavator is on firm ground, and most importantly, when it is cold.
Now, you need to, yet again, check your excavator’s instruction manual to know how to position your excavator’s accessories like the boom and the bucket to get accurate readings.
Now, there are general safety precautions that you should implement to ensure that you complete the process safely.
Check them out:
You should first remove the excavator’s key from its ignition. You should also ensure no pressure in your excavator’s tank before you remove your excavator’s hydraulic cap. This should be done before adding more oil to the excavator’s engine.
Remember:
Use the oil that your excavator’s manufacturer specifies. This rule should apply as a general rule to all excavator owners and operators.
10. How Can I Change The Oil In My Excavator Engine?
Changing the oil in your excavator engine is not a difficult process. Any operator or mechanic can do it well. You’ll only need to pay attention to what you are doing. You’ll also need to know what goes to ensure that you fix the excavator engine back to how it was before servicing.
Check out this short video that illustrates how to perform an oil change in your excavator engine. It’ll show you how to drain, refill and perform filter change.
Remember:
Ensure that you use the correct amount and, most importantly, the correct type of oil during servicing. It’ll help your engine last longer and work effectively and efficiently.
11. How Can I Properly Maintain My Excavator Engine?
There are four primary ways that you can use to keep your excavator’s engine in its best condition.
The first way to maintain your excavator engine is always to get rid of water in the separator. This water comes as a result of dropping temperatures at night after working during the day. It is imperative to drain this condensation water because it might get into your excavator’s injector.
In some cases, the water corrodes your excavator’s injectors, where it is turned to steam.
Bottom line:
Failure to drain this water may cause your excavator engine to fail. It is the most common cause of engine failure in excavators.
The second proper way to maintain your excavator engine is to change components once they need replacement. For example, you should not change or access your excavator’s air filter until the excavator’s check air filter switches on at the dashboard.
The third proper way to maintain your excavator engine is to replace parts with new ones from the brand’s company or a reputable company. Using low-quality parts may seem cheap, but they damage your engine – meaning that they are expensive in the long run.
The fourth way is to ensure that you do not mix hydraulic fluids. Do not mix one type of engine oil with another type. Engine oils perform the same tasks, but they do not have the same components. They might form a thick gel-like oil inside your excavator’s engine.
12. What Is The Process Of Replacing An Excavator Engine?
Replacing your excavator engine involves removing a damaged engine and installing a new one.
It is a long and complex process that will require you to contact a skilled professional. You need to engage a skilled professional so that you’ll not void your warranty if your new engine has issues.
Check this out:

13. How Frequently Should I Change My Excavator Engine Oil?
Excavator engine oil change varies because of the different brands in the market today. It’ll be best if you’d strictly adhere to your excavator manufacturer’s specifications on engine servicing.
However, you should not allow your excavator to use the same engine oil after every 500 operating hours.
Check this out:
You need to record the duration in hours when your excavator works. It helps you maintain your excavator’s engine, as well as other engine-related characteristics such as fuel consumption. Once your excavator hits 500 hours of operating time, you’ll need to replace the hydraulic filter, change the fuel filter, and change engine oil.
14. How Can I Properly Troubleshoot My Excavator Engine Problems?
You can troubleshoot your excavator engine problems using the following ways:
You’ll first need to test your excavator engine’s output power. Is the output power lower than what the engine should produce? If yes, consider checking your fuel quality, fuel pressure, or incorrect fuel quantity setting value.
You should also consider checking for a non-functioning engine cylinder, faulty brakes, or carbon deposits on the excavator’s engine turbocharger.
Your excavator’s speed may also be slower than usual due to leakages in your excavator’s hydraulic system. The hydraulic system may start leaking because of the normal wearing out of parts when the excavator works.
When there is leakage in your hydraulic system, the engine will run slow because of the insufficient flow of hydraulic fluid. You’ll need to carry out a complete overhaul to replace the worn-out parts of your hydraulic system.
Thirdly, your excavator may also be running normally, and then it suddenly slows down. You need to check your circuit fuse.
15. How Should I Repair My Excavator Engine?
Now, it’s normal for your excavator engine to get damaged over time and even wear out. What’s important is how you repair it when it gets damaged.
Here’s how you should repair your excavator engine:
You should first know which excavator engine component is damaged. You can troubleshoot your excavator engine by first understanding the abnormal behavior in the engine, for example, a weak engine that produces a lot of smoke.
You’ll find out that this happens because there is no proper internal combustion, thus producing little power and black smoke. Keep in mind that black smoke is a sign of improper combustion in the internal combustion chambers.
Your final diagnosis will be that your excavator engine is weak, and it fails to supply enough pressurized oil to the three main pumps.
You can then start repairing your excavator engine by contacting a skilled and certified professional. Doing this is important because it’ll help you avoid nulling your warranty. It’ll also help you know other problems that your excavator engine may have.
Besides contacting a skilled and certified professional, you need to buy your excavator engine spare parts from a reputable company. You’ll be sure that the parts you buy are original, and they’ll help your excavator work effectively and efficiently for a long time.
KS manufacturers excavator engine parts. Apart from manufacturing, our company also supplies and exports these parts to different countries worldwide. We have formed deep professional working relationships with top logistics companies all over the world. These companies include DHL, TNT, FEDEX, etc.
Before shipping over parts to you, we ensure that packaging is done correctly to prevent damage during transport. You can be sure that you’ll receive world-class quality parts. In case the parts are defective, KS guarantees you a 90-day warranty.
16. What Causes An Excavator Engine To Blow-By?
Your excavator engine blows by because of leakage from the cylinder going into the crankcase. You’ll find out that it usually starts with the formation of carbon on top of your engine’s ring grooves. You’ll also find out that your cylinder may glaze.
Both of the above scenarios allow your cylinder to leak down and burn some oil. When the oil continues to burn, it forms bigger deposits on your rings. This situation causes your engine to become extremely stressed.
The first thing you can do to fix this problem is to add a decarbonizer from a reputable company when adding diesel to your machine. The second way to solve this problem is using flushing oil concentrate during an oil change.
The flushing oil concentrate cleans your engine by targeting tough baked oil deposits and other unwanted materials that form a thick sludge in your engine.
You’ll know that your engine is under a lot of stress when it produces a lot of black smoke than usual. It’ll also have low efficiency on fuel consumption, and its performance will not be as effective as usual.
It’s important for you not to ignore these issues because they can cost you a lot of money. Besides, you can easily handle the problem using either of the above two solutions, depending on which one favors your current situation.
17. Why Is My Excavator Engine Weak And Noisy?
Your excavator engine may be weak and noisy because of different reasons. Check them out:
The first reason why your excavator engine is weak maybe because of air blockages in the engine. Consider checking your air filter indicator in your cab. If the indicator is on, you’ll need to change the air filter.
The second reason why your excavator engine is weak is because of blockages within the fuel filter restrictions. Your fuel filter may be clogged, and it’ll require replacement as soon as possible.
If the air and fuel restrictions are absent, you’ll need to ascertain that the weakness is not real – not perceived. You can do that by using your machine’s service manual to check the cycle times of your excavator’s swing, bucket, boom, stick, etc.
This process will require you to have a stopwatch to measure the duration of these cycles.
The service manual will show you whether the duration is within the excavator’s specified time range or not. If it falls within the specified duration, then the excavator does not have low power. The weakness was perceived.
If it did not fall within the specified time, then you’ll know that your engine is weak. You’ll need to contact a skilled and certified professional to help you out.
The last diagnosis is to adjust your valves.
Here’s the truth:
Valve adjustment is a complex process. It would be best if you’d contact a professional to help you out in the process. If you are a professional yourself, you can find the process in your machine’s operation’s maintenance manual and not the service manual.
It’s important to adjust your excavator’s valves. You shouldn’t overlook the valve adjustment process.
The reason why your excavator engine is noisy is that the bottom engine guard plate is broken.
If the bottom engine guard plate is broken or damaged, your excavator engine’s oil pan will most likely be dented. The guard plate protects the engine from denting, and therefore it prevents denting your excavator engine oil pan.
Once you accelerate, the guard plate will contact the oil pan, and therefore it will produce a lot of noise. The best way to resolve this issue is to remove the bottom engine guard from your excavator and straighten it.
Our service reps are always available to hear you out, answer your questions, and advise you accordingly. They’ll also help you out with your orders.
18. Why Does My Excavator Engine Produce Black Smoke?
Your excavator engine uses a diesel engine. It’s normal for diesel engines to produce black smoke. There are three types of smoke that are associated with diesel engines.
You can have black smoke, white smoke, or blue smoke.
The black smoke indicates that there is an imbalance between the fuel and the air mixture.
That process is called combustion. When there is an imbalance between the fuel and air mixture, your diesel engine will produce suit.
Your excavator engine produces black smoke either because of bad injectors or injectors with deposits. These injectors determine how well the fuel is injected into the engine. You could also have a faulty injector pump or a bad air filter.
You can acquire your diesel engine fuel injector from KS today. You’ll have a 90-day warranty once you acquire it. We will ship the part over to you, regardless of whether you’ve ordered a single diesel engine fuel injector or you’ve ordered them in bulk.
We do not have a minimum order quantity (MOQ).
Remember, the air is important in the combustion process. When there is restricted airflow to the engine, it’ll undoubtedly produce black smoke.
Blue smoke can occur because of different reasons:
The probable cause for your excavator producing blue smoke is bad valves. Bad valve stems also contribute significantly to the process. You could also have worn-out piston rings or cylinders. They can allow leakage of oil to the wrong places, e.g., cylinders.
The final probable cause is excessive feeding of engine oil to your excavator engine. You need to use the specified amount of excavator engine oil as instructed by your excavator’s manufacturer, depending on its make and model.
White smoke is caused when your fuel is not being burnt properly. It is caused by low engine compression. Another cause could be water in the fuel to the fuel pump timing being thrown off because of another internal blockage that prevents fuel from reaching the fuel pump.
Your excavator should not produce a lot of smoke – more than what is normal for diesel engines.
19. Where Can I Find An Excavator Engine For Sale?

Contact us today for more about our services, products, and shipments. Our skilled service reps will help you out.
20. Why Is My Excavator Slow?
Your excavator may be running slow, even when your engine works fine.
The two primary pumps supply oil under high pressure to the swing motor, track motor, and other excavator accessories. The third hydraulic pump has a lower amount of pressure compared to the first two.
The reason why your excavator runs slow is probably because there is an issue with the two main pumps that drive power from the engine to the rest of the excavator. The excavator’s engine usually shares power equally across the two hydraulic pumps.
Your excavator will show you a problem with your excavator hydraulic pumps when one of the tracks is slower than the other.
You can solve this problem by checking the excavator’s power unit. Your engine needs to be in good condition for it to work properly. If your engine is in good condition, proceed to check your excavator drive coupling. It’s normal for them to wear out over time.
You can also check your hydraulic fluid level.
KS understands that finding the correct fault that prevents your excavator from working slowly can be time-consuming. That is why our service reps are always there to help you out 24 hours a day, seven days a week.
21. What Is The Service Life Span Of A Properly Serviced Excavator Engine?
The average lifespan of most excavator engines is 10,000 operating hours. By the time your excavator engine clocks 10,000 hours of operating time, you’ll have replaced almost every part of the engine.
Therefore, it is important to take care of your excavator’s engine to enjoy its benefits as it works tirelessly for you.
