Spare Parts for Kubota, Bobcat, and Yanmar Mini Excavators by MAQ Parts 

Let's first talk about different spare parts for mini excavators provided by MAQ Parts.

1. Spare Parts for Undercarriage 

The undercarriage of a mini excavator is a robust and complex system comprising several parts. All of them must be in excellent condition for the undercarriage to work effectively. Let's discuss these spare parts in detail below and understand what they do.

1. Rubber Chains 

Rubber chains in an undercarriage are specialized tracks made of rubber or rubberized materials. Some more interesting things to know about Rubber Chains are as follows:

  • They enhance traction by gripping the ground surface, allowing the excavator to stabilize challenging terrains.
  • The rubber chainsreduce the impact on delicate surfaces, such as asphalt or concrete, preventing damage during operation.
  • They help minimize noise levels, making the machine more suitable for noise-sensitive environments.
  • Rubber chainsalso improve flotation, enabling excavators to work efficiently on softer grounds like mud or sand. 
  • Lastly, they contribute to operator comfort by reducing vibrations and jolts, resulting in a smoother and more controlled operation overall.

2. Running Rollers 

Rollers are metal wheels that support the machine's weight, distributing it evenly across the tracks. They also assist in guiding the tracks, ensuring proper alignment, and reducing lateral movement. By rotating smoothly, they help reduce friction and extend the lifespan of the tracks.

Additionally, rollers aid in absorbing shocks and vibrations during operation, enhancing operator comfort. Overall, rollers contribute to mini excavators' stability, maneuverability, and longevity.

3. Idlers 

Idlers are rotating wheels or pulleys positioned at the front of the machine that maintains tension in the tracks, ensuring proper engagement with other components. They also guide the tracks, keeping them aligned and preventing excessive wear. By rotating smoothly, they minimize friction and reduce energy consumption. 

Moreover, idlers absorb shocks and vibrations, enhancing operator comfort. Their presence contributes to the overall stability and maneuverability of mini excavators.

4. Sprockets 

Sprockets are toothed wheels that engage with the tracks. They play a vital role in the overall operation of the machine. The sprockets transfer power from the engine to the tracks, driving the excavator forward or backward.

As they rotate, they engage with the track links, propelling the machine in the desired direction. Their teeth mesh with the track chain, providing traction and smooth movement. Sprockets also help maintain proper tension in the tracks and distribute the machine's weight evenly across the undercarriage, contributing to stability.

2. Oils & Filters 

An oil filter removes impurities, such as dirt, metal particles, and sludge, and maintains the cleanliness and quality of the engine oil. It helps extend the engine's lifespan and improve its performance.

Regularly replacing it is necessary to maintain the efficiency and effectiveness of the filtration process. Similarly, MAQ Parts also provides oils for service that a mini excavator needs every 500 hours for efficient functioning. 

3. Pins and Bushings 

Pins and bushings are present in the arms and joints of mini excavators and are critical for their functioning. The pins act as pivot points, allowing rotation and articulation of the excavator's arms and attachments. Bushes, on the other hand, provide a smooth and durable surface for the pins to rotate within, reducing friction and wear. 

4. Cab Glass 

A cab glass refers to the transparent panels or windows installed in the cab of a mini excavator.

  • Firstly, they allow operators to see the surrounding environment and the work being carried out.
  • Secondly, cab glass shields the operator from external elements such as dust, debris, and weather.
  • It also helps reduce noise inside the cab, providing a more comfortable working environment. 

5. Engine Parts 

Let's now delve into some engine parts of mini excavators available at MAQ Parts. They have a wide variety, including water pumps, fuel pumps, water coolers, alternators, and many more.

1. Water Pump 

A water pump is a mechanical device that circulates coolant throughout the engine. It pumps coolant from the radiator to the engine, allowing heat to be dissipated. Therefore, it helps maintain optimal engine temperature and prevents damage.

2. Fuel Pump 

A fuel pump delivers fuel from the tank to the engine's combustion chambers. It ensures a consistent and pressurized fuel flow, enabling the engine to operate smoothly and efficiently. Hence, it is vital to maintain proper fuel delivery and engine performance.

3. Starter Motor 

starter motor is an electric motor that initiates the engine's rotation during startup. It engages with the flywheel to crank the engine, igniting the fuel-air mixture and initiating combustion. The starter motor is crucial for starting the engine and getting it running smoothly.

4. Alternator 

Alternators convert mechanical energy into electrical energy. They generate electricity to power the electrical systems and recharge the battery while the engine runs. Alternators ensure continuous electrical power supply for various components, such as lights, controls, and accessories.

5. Water Cooler 

A water cooler, also known as a radiator, is a heat exchange device that helps dissipate excess heat from the engine coolant. It comprises a network of tubes and fins facilitating heat transfer to the surrounding air. The water cooler helps prevent overheating and potential damage to the engine.

6. Pistons & Gaskets 

Pistons are cylindrical components that move up and down inside the cylinders and convert the pressure generated by the combustion process into rotational motion. Gaskets, on the other hand, are seals placed between engine components to prevent leakage of fluids or gasses, ensuring proper compression and sealing. 


As you can see, spare parts for mini excavators are essential to keep the latter running smoothly. If you're in the construction industry, keep an eye on all these components and ensure you replace them on time. 

However, purchasing them from a reputable name, such as MAQ Parts, is critical. We have been providing mini excavator spare parts for years, earning our customers' trust worldwide. So, whether you're looking for spare parts for Bobcat, Yanmar, or Kubota, MAQ Parts is the right place.
