Essential Skills for Excavator Maintenance and Repair

A qualified construction machinery operator should not only master the driving skills but also understand some basic maintenance and repair of the machinery. However, not every mentor teaches these aspects. Some novice excavator drivers may barely manage tasks but lack knowledge about the gearbox and turntable needing gear oil, let alone knowing when to replace them. They might confuse engine oil filters with diesel filters or struggle with air bleeding or identifying the number of hydraulic oil...

Common Issues with Various Filters in Excavators

Common Issues with Various Filters in Excavators

The fuel filter removes impurities such as oxidized iron and dust from the fuel, preventing blockages in the fuel system, reducing mechanical wear, and ensuring the stable operation of the excavator's engine. Under normal circumstances, the replacement cycle for the excavator's engine fuel filter is to replace it after the first 250 hours of operation, and then replace it every 500 hours of operation thereafter. The specific replacement time should be flexibly determined based on the quality...

Why Excavator Engines Need Timely Oil Changes

Why Excavator Engines Need Timely Oil Changes

The Importance of Timely Engine Oil Replacement for Excavator Engines Why should excavator engines replace engine oil on time? Engine oil has a shelf life, and over time, its performance deteriorates, leading to accelerated wear of mechanical components. Engine oil undergoes physical and chemical changes during high-temperature operation inside the engine, which also affects its mechanical properties. As the engine runs for an extended period, impurities in the engine oil increase, which can accelerate...

Why Do Excavators Face Starting Issues in Cold Regions?

Why Do Excavators Face Starting Issues in Cold Regions?

When operating excavator in high-altitude and cold environments, starting difficulties are often encountered. To initiate the engine, some experienced drivers even resort to methods like heating the oil pan, pouring hot water into the engine, or pushing the vehicle downhill. Today, let's discuss why it's challenging to start excavators in high-altitude and cold regions and explore corresponding solutions. Diesel engines are compression-ignition internal combustion engines, and starting them...
