Pro Tips, News & Events

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.

Regular maintenance and inspection of various filters and the cooling system are crucial for ensuring equipment operates smoothly and extends its lifespan.

Hydraulic oil leaks in excavators can cause weak digging and slow operation. Look for oil stains or dust on the cylinder rod, which may indicate a leak or bad seal. Ignoring leaks can contaminate the hydraulic system and lead to expensive repairs. Fix leaks quickly and replace seal kits if needed. When replacing, use the correct part number, carefully disconnect hoses, and check all parts. If unsure, get professional help. Common leak causes include worn seals, damaged rods, and wrong hydraulic fluid.
