The water pump is crucial for the cooling system of heavy equipment, preventing overheating issues. Customers often face breakdowns due to overheating, especially in hot weather, and seek to reduce repair costs. Proper repair involves removing old components, cleaning the housing, and installing new parts using a hydraulic press. If unsure about the repair steps, you can replace the entire water pump at a lower cost through FridayParts.
CASE defines the B series-CX290B as a powerful and speedy hydraulic excavator as it has three working modes(A-mode, H-mode & SP-mode*) that allow the machine to have higher breakout force, greater swing speeds, and torque. According to the test, CX290B is about 5% improved in productivity than that of other hydraulic excavators.
* A-MODE: for grading, lifting, and precision work.
*H-MODE: the best balance between productivity and fuel economy.
*SP-MODE: extra speed and power for the most demanding jobs that require maximum productivity
The variable control hydraulic pump is one of the main features of CX290B, which helps the excavator work smoothly and rapidly during heavy load work.
Caterpillar 320D is known as an excavator that can maintain high performance with little fuel consumption. This is because the machine engine, 3066 ATAAC, is aftercooled and turbocharged with six cylinders. Moreover, the excavator can control the engine speed automatically according to different load conditions, which also helps the excavator reduce fuel consumption and sound levels.
The 320D spare part is one of the high-demanded products from our clients. To help customers get a better understanding of the equipment and part information, this post organizes basic machine specifications and part information.
The final drive, consisting of a hydraulic motor and gearbox, is crucial for heavy equipment as it transfers power to the undercarriage tracks. Maintenance is essential due to the high replacement cost. Common causes of failure include water contamination and damaged seals, which reduce lubrication. Regular oil checks and changes are vital, as old or contaminated oil can lead to failure. The frequency of oil changes depends on the machine type and usage, but checking oil quality frequently is recommended, especially after operating in mud or water.
Komatsu PC18MR-3 is a mini digger with horsepower 11.2kW/15HP and a bucket capacity is 0.022 m3-0.044 m3. The excavator aims to increase the flexibility of the equipment when it works in a cramped place. The machine’s operating weight is 1780kg, and it has a tight tail swing which allows operators to focus more on the digging without worries about a rear swing impact.
The global construction industry has been growing steadily since 2020, driven by effective COVID-19 control, population growth, and infrastructure development. In the U.S., President Biden’s $2.3 trillion infrastructure plan indicates continued growth. The construction equipment market, especially for earth-moving machinery like excavators, is also expanding. Emission regulations may increase demand for eco-friendly equipment, boosting the rental market and international trade in equipment and parts. FridayParts aims to support this growth by providing quality aftermarket parts and building long-term partnerships with industry stakeholders.
Store equipment in the shade to prevent overheating and reduce operation during peak sunlight hours. Ensure air conditioning is used properly by keeping doors and windows closed and regularly checking filters. Monitor water temperature gauges and allow the machine to cool before shutting it off. Check oil quality daily to prevent deterioration, and maintain battery power by storing it properly and charging it regularly.
Regular maintenance of excavator undercarriage components is crucial to prevent efficiency loss and excessive wear. Key tips include checking and tightening bolts on track shoes, promptly replacing bent track shoes, inspecting and replacing damaged chain guards, monitoring sprocket wear and avoiding frequent backward operation, maintaining proper track tension based on terrain, and keeping the undercarriage clean.
Most excavator operators encounter various failures during operation, with the most common issue being that the excavator won’t start. This article explores possible reasons and solutions for this problem, focusing on how to inspect the electrical and engine oil circuits.
For most hydraulic excavators, the operating speed is inversely proportional to the load during digging. However, if the hydraulic pump control system is malfunctioning, the excavator cannot work efficiently under different working conditions. Therefore it is essential to know the excavator control system from different manufacturers, such as Komatsu CLSS system, CAT electronic power control system……
To check the speed drop of an excavator, start by testing the engine’s output power. If it’s lower than the rated power, inspect components like air valves, fuel injectors, the turbocharger, and the hydraulic pump. Common issues include poor fuel quality, low fuel pressure, incorrect valve clearance, and turbocharger carbonization. If the engine’s output power is normal, ensure the hydraulic pump’s flow rate matches the engine’s output. Speed issues may also stem from the pump control system, requiring checks of the electrical, hydraulic, and mechanical transmission systems. For more details, watch the video on replacing heavy undercarriage components.
Regular maintenance and inspection of various filters and the cooling system are crucial for ensuring equipment operates smoothly and extends its lifespan.
