Excavator Turbo – The Definitive FAQ Guide

The Excavator Turbo FAQ Guide is written for those who want to find out more about a turbocharger.

It is common knowledge that turbocharged engines are more efficient than non-turbocharged engines. This guide will explain why this is the case.

This FAQ Guide pertains to excavator turbo, types, cost, efficiency, benefits, lifetime, working principle, failure symptoms, and much more.

This guide will prove to be a helpful information resource either you are a beginner or a professional.

1.    What is the function of the Excavator turbo?

The function of an excavator turbo is to compresses air that would otherwise be bypassed by an ordinary intake system and used as a combustion source for burning gasoline.

The excavator turbo forces extra air into engine cylinders, creating higher pressure.

This raises the amount of oxygen available to burn fuel, which increases power and decreases fuel consumption.

The result is a higher rate and wide range of power generation and reduced weight and fuel consumption, resulting in more power for your penny.

Excavator Turbo comes in different sizes, operating on exhaust gases produced by various sized engines.

They can be used on both diesel and petrol engines, depending on their size and power requirements.

2.    Can an excavator turbo damage your engine?

Yes, an excavator turbo can damage your engine.

Excavator turbo used in some vehicles and equipment put out a tremendous amount of boost pressure.

This boost is usually on the order of 50 to 80 psi with new units. It’s set to work with an engine rated seven or more compression ratio.

Such a huge pressure may result in damage to your engine components.

The pores and fins on the surface of the compressor wheel increase airflow into the engine.

However, contact between this metal material and the engine components increases friction in the excavator turbo.

This can cause a high load on the power-generation parts of the engine causing permanent damage.

3.    How much speed does an excavator turbo add?

An excavator turbo with a boost pressure ranging from 6 to 8 pounds can develop more power that lies in the range of 15 to 25% compared to an ordinary engine.

Every engine is different, with a boost pressure (critical to protecting the turbo) approaching twice the standard level and exhaust gases that can be up to three times as hot as an engine without a turbo discharge.

Boost pressure is a measure of how much air an engine can push into the cylinders.

Boost pressure is directly proportional to the amount of boost pressure provided by an excavator turbo.

An excavator turbo ability to provide more boost pressure than a normally aspirated engine can is what makes it special.

Add a turbo to your excavator, and you’ll get faster engine speeds.

You’ll burn less fuel for every hour of digging, which means more time to work and more money in your bank account.

4.    How much does a good excavator turbo cost?

The price of high-quality construction equipment is rather high.

Such units have a larger diameter, storage capacity, and greater overall efficiency than their production counterparts.

The quality of turbochargers has a noticeable influence on the cost of an excavator.

The cost varies depending on the excavator model and type.

The cost of an excavator turbo usually varies from $100 to $500 per piece.

It’s important to note that there are many inexpensive but poor-quality options on the market.

If you want to ensure an effective machine, you need to invest in a durable, high-performance model that can serve you in the long term.

5.    Why does excavator turbo whine?

Excavator turbo whine is noise or rattling sound produce by an excavator turbo.

The main reasons for this are low power generation and the negative effects of exhaust gases on the body.

As well as the power output and fuel efficiency, both turbines thrust bearings and compressor blade bearings are damaged.

Both components of an excavator can suffer sub-optimal performance due to turbocharger noise, vibrations, and accelerated wear caused by failures of bearings caused by the relatively constant high level of vibration.

Excavator turbo whine is a common complaint among excavator operators that it drains them mentally and makes them feel tired.

6.    How many miles do excavator Turbos last?

The calculation of an end of life for an excavator turbo will not be as simple as with a car because there are many considerations.

These can include the operating conditions, such as several starts, use, and age of coolant and engine oil, machine temperature – ambient, exhaust gas temperature, etc.

It can also include the quality of the materials used to make the parts.

Heavy-duty excavator turbos regularly last around 200,000 miles, which is an average estimate.

It can be more or less dependent upon how properly you follow maintenance requirements for your excavator turbo.

7.    What is the disadvantage of an excavator turbo engine?

There are several disadvantages of excavator turbos. Some of the main disadvantages are listed below:

  • Spool up time: To spool up a turbocharger, it needs time to spin up. This factor is dominant in large excavator turbos.
  • Excavator boost threshold is a concept in turbocharger design that specifies the maximum pressure an engine can push. Excavator turbo has been adapted to boost at a much lower engine speed. This allows the boost to be turned up for more power at higher RPMs. Such excavator turbo lack operation at the broad range of RPM.
  • Too much power: a turbocharger’s boost pressure can be too high for some applications, and, in these cases, the engine will not safely run at its optimum power.
  • The heat and pressure of an excavator turbo can cause oil feeding issues, and this might require extra plumbing.

8.    How often does the excavator turbo need to be replaced?

There is no hard and fast rule for replacing your excavator turbocharger.

Different models are designed with varying purposes for various applications, both in terms of the frequency they are run and the type or grade of oil, fuel, and environment in which they are run.

Excavator turbochargers are designed to last a very long time.

In practice, it’s possible that with an expertly maintained machine, and fuel of sufficiently high octane and low water content (preferably synthetic), turbochargers can be run for years or even a decade before they need to be replaced.

While many don’t reach the end of their lives until they’ve run for tens of thousands of hours, this is only compliant maintenance.

It all comes down to careful maintenance and regular servicing, including replacing the compressor wheel bearings in turbochargers which are the most likely components that fail prematurely.

9.    What are the specifications of the excavator turbo?

The specifications of excavator turbo are listed below:

Sr. No. Excavator Turbo Specifications
1 Horsepower 80
2 Revolution per minute 300,000
3 Volume capacity 100 cc – 500 cc
4 Compressor wheel 32 mm
5 Inducer 22.63 mm
6 Exducer 32 mm
7 Trim 50
8 A / R 0.32
9 Bearing Journal
10 Coolant Oil
11 Compressor Single-stage / Centrifugal
12 Turbine Fixed geometry / twin entry/ radial
13 Maximum torque 177 kW
14 Maximum Power 840 Nm

The specification of the excavator turbo varies from model to model. Large excavator turbos have greater specifications and also the cost associated.

10.      What does excavator turbo efficiency mean?

The efficiency of an excavator turbo determines how good or bad it is.

If the efficiency is less, it is considered a bad excavator turbo, and if the efficiency of excavator turbo is good, it is regarded as a good excavator turbo.

The average efficiency added by an excavator turbo overall is as follows:

Excavator turbo can supply any application with a wide range of capacity ranging from 0.55 to 150kW.

It can get 25%-30% fuel economy improvement and reduce exhaust gas emissions by 60%.

It results in the working efficiency enhancement of up to 20%.

The use of turbochargers improves the efficiency of diesel engines by reducing the amount of un-burnt or unused exhaust gases and increasing engine speed, thus improving fuel economy and maximizing engine power output.

11.  What are the components of the excavator turbo?

An excavator turbo comprises several components. The main features of a turbocharger are listed below.

Components of excavator turbo

  • Electronic actuators
  • Cartridges (excavator turbo cores that are compressed for prime fit)
  • Pneumatic and vacuum starters
  • Electrical serving drivers
  • The housing of the compressor is the part that surrounds the excavator turbo compressor wheel.
  • Swap out parts to fix out a minor issue
  • Compressor wheel
  • Turbine rotors and impellers
  • Turbine housing
  • Nozzle ring housing
  • Bearing housing
  • Backplates
  • Heating shields provide a shield from heat emerging from the turbo excavator core
  • VNT nozzle ring, nodes for controlling the geometry of VNT
  • VNT gasket
  • Gasket kit
  • Actuator sensors
  • Parts of electrical actuators

12.      What materials are used in manufacturing excavator turbo?

Materials used to manufacture excavator turbochargers are materials taken from various mines of steel, iron, aluminum alloys, bronze, titanium, magnesium, and other alloys.

These materials are used for the manufacturing of various components of the excavator turbo.

Materials use

Cast iron and steel are used to make turbochargers, while Aluminum is used to make compressor wheels.

Each material has its strength and durability and is used as a standard material around the globe for the specific pressure and temperature range to which it is subjected.

It would help if you chose an Excavator turbo made of high-quality metal parts with a strong wear resistance to ensure high reliability.

The materials for the products can be non-ferrous metals, ferrous metals, and some light alloys.

13.      How does an excavator turbo work?

The excavator turbo consists of two main parts, including turbine wheel and turbine housing.

The turbine wheel receives energy from the exhaust gas.

To start the compressor, the turbine spins. As the rotating shaft pulls in air, it compresses it.

The compressor housing works on the principle of diffusion. It alters low velocity and high-pressure air into high speed and low-pressure air.

The air from the compressed air tank is directed to the engine of the excavator.

There this compressed air is utilized to burn extra fuel that leads to the production of additional power.

14.      What are the failure symptoms of my excavator turbo?

Several signs lead to the ultimate failure of your excavator turbo.

Excavator Turbo Failure

Power Loss:

If your car feels slow to respond or doesn’t accelerate as quickly as it used to, it could be because its turbocharger is failing.

A turbocharger that is damaged may be inflicting serious power limitations on your car.


If your excavator turbo emits a loud and annoying whine, it may be time to schedule an appointment with a mechanic.

This noise does do sound a little like a dentist’s drill. It can be a sign of turbo failure.

Exhaust Smoke:

An oil leak into the exhaust system is responsible for the unique grey smoke it produces.

The leaking oil can burn off in a matter of minutes or hours, depending on external temperatures. Oil leaks can also cause corrosion and premature wear in engine parts.

This may be due to a damaged excavator turbo.

15.      What causes the failure of my excavator turbo?

There are several reasons for the failure of an excavator turbo. Some of the main reasons are listed below:


A lack of lubrication, the wrong grade of oil, or poor-quality oil can damage your engine. If not treated, lubrication problems may cause the turbocharger to become damaged.

Causes of excavator failure

Cracks in the housing can restrict airflow to the turbo, making it less efficient and reducing power output.

Faulty Seals:

Leaks in the engine exhaust system cause the turbocharger to work harder.

In addition, a leak can cause serious damage to other components in the engine, such as the catalytic converter and the air intake manifold.


Dust particles, dirt, and other foreign materials can get into an excavator’s turbo intake system, potentially clogging the main bearings or causing further damage.

Air filters and engines both play a role in keeping your vehicle running. So, if your car has been depositing, chances are the intake is to blame.

Foreign objects that enter the engine can cause damage, but more often than not, they result from leaks at the intake.

Wear and Tear:

Turbochargers are made to last. They are designed to handle up to 150,000 miles of driving, which means they should last for an extended number of years.

Although the materials used in manufacturing and how hard you use your excavator turbo it varies.

16.      Can I drive with a blown excavator turbo?

Yes! You can drive even if the turbo is blown, but the engine will be somewhat weaker without it.

Technicians call a blown or defective turbocharger “Turbo coma.”

Blown Turbo

be careful: there are minimum compressor wheel rotation speed and pressure values that Turbo Control Unit (TCU) uses to manage exhaust gas recirculation and injection advance degree.

When the engine speed goes below these values, the engine loses its power output.

It is recommended to drive your excavator only when it is essential.

You can experience various signs of failure before your turbo excavator gets blown. Therefore, you can follow preventive measures and get it repaired before it fails.

17.      What are the advantages of excavator turbo?

There are several advantages of an excavator turbo. Some of the main benefits are listed below:

  • The excavator engine will undergo significant improvement in horsepower.
  • A smaller engine can produce a lot of power per pound than a larger one, makes it easier to move heavy objects.
  • Engines with smaller common mass and lower revolutions use less fuel to idle, thus lowering carbon emission.
  • Excavator turbo often uses exhaust gas recuperation to boost efficiency. For example, this system uses exhaust gases to spin a turbine, thus improving overall efficiency.

18.      What is excavator turbo surging?

Excavator turbo surging results from a transient over-boost condition of the exhaust pressure in the compressor inlet manifold upstream to the turbocharger.

A large amount of noise accompanies the surge.

Turbo surging may destroy the turbocharger and related components and create a great potential for significant fuel savings.

Excavator Turbo Surging

Excavator turbo surging is a condition encountered in some turbocharged diesel engines.

It can occur when the air supply to the engine is insufficient, such as at high ambient temperatures or high speeds or altitudes.

There may be a temporary mismatch between the amount of air required to burn the fuel and the amount supplied during such conditions, which can cause cylinder pressures to exceed design limits.

19.      What are the types of excavator turbo?

Several types of Excavator turbos can be installed in your excavator.

These types are given below:

Single Turbo:

They’re popular for their ability to produce more power than a traditional engine of similar size while at the same time weighing less and taking up less space.

Single Turbo

Twin Turbo:

Twin-turbo engines are two turbochargers attached to a single-engine.

V6 or V8 engines can be modified by having each cylinder bank fitted with its turbocharger.

Twin Turbo

Twin Scroll turbo:

Twin-scroll turbos are mounted in the same way as single-scroll turbos, but the inlet and exhaust manifolds are divided.

The left and right exhaust assemblies deliver their separate exhaust gases, which enter the turbos separately.

Twin Scroll Turbo

VGT turbo:

A VGT is one of the most efficient turbomachinery components ever developed in automotive and commercial vehicle markets.

It is a highly efficient combination of a gas compression turbine with variable geometry and a rotary compressor that reduces sound levels, increases fuel efficiency, and improves power density.

VGT Turbo

VTS turbo:

As the name suggests, a VTS turbocharger is a combination of two different types of turbochargers.

In this combination, one turbocharger is used with two sets of twin-scroll turbochargers.

The first set of twin-scroll turbochargers provides a bigger boost and more power, while the second set of twin-scroll turbochargers provide minimal increase and lower power.

VTS Turbo

Electric turbos:

An electric turbocharger allows a turbocharged engine to operate efficiently at lower engine speeds.

The electric motor spins the compressor in the turbocharger from start until the engine reaches higher RPMs. After that, the power of the exhaust volume is sufficient to make the turbocharger work effectively.

Electric Turbo

20.      Can the excavator turbo be repaired?

Yes, if you are looking to repair your turbocharger, you need to choose a mechanic or company with enough knowledge regarding this repair.

However, it is often more cost-effective to repair your excavator turbo than replacing the entire turbocharger.

While repairing, make sure to replace the components that are damaged with the same material with which the original one is manufactured.

This can make a difference and allow you to use it for comparatively longer.

21.        What is the role of the bypass valve in excavator turbo?

The bypass valve plays a very important role in ensuring that the compression process is completely the same.

While designing this valve, engineers focus on its capacity and effect on overall performance.

It has a direct impact on the amount of boost produced in the engine and engine speed.

This specific valve adjusts the amount of air flowing from the compressor wheel to the turbine wheel.

Bypass Valve

The turbocharger works with soot particles and heat that are formed inside the engine.

It is another only way to extract power from older engines that were not built for this purpose.

22.      What is the maintenance requirement of the excavator turbo?

The maintenance requirement of the excavator turbo is quick and simple.

The maintenance of the excavator turbo is mainly to clean the compressor wheel, oil the rings, check the air filter, and clean engine oil.

In the process of using, you should keep an eye on the engine temperature and do not run your excavator in a working environment that is too hot or too cold.

When working in a coal mine, removing large stones, or other situations, the temperature is higher.

As a result, the wear will be faster, which requires companies to regularly check the engine’s temperature and replace the turbochargers in time.

The fuel system should also be checked frequently to avoid mixing diesel and gasoline or low-quality fuel into the fuel tank.
