KAH14050 Excavator Parts - Precision & Durability by SPARKLING

   Is your excavator’s engine lacking power, consuming more fuel, and emitting black smoke? Chances are its "breathing" is blocked! The air filter assembly is the "lung defense line" of an excavator. Composed of a pre-filter, main filter, safety filter, and air intake hose, it filters impurities to protect the engine. However, many operators forget to replace the filters or incorrectly install the hoses, leading to engine wear. This article explains the assembly’s structure, risk factors, brand comparisons, and maintenance methods in plain language—even beginners can understand it, ensuring the excavator "breathes smoothly"!

   Does the excavator body tip backward when lifting the boom for loading, or the entire machine shake during slewing operations? Chances are the counterweight is causing the problem! As the "balance core" of the excavator, the counterweight consists of cast iron blocks, mounting bolts, and vibration pads. It offsets the overturning force at the front end with its weight—without it, the excavator can’t stand steady or work properly.

   When operating an excavator, have you ever encountered issues like the machine body failing to rotate, abnormal noises during rotation, or automatic "slipping rotation" when working on slopes? Most of these problems stem from the "large turntable" — technically known as the slewing ring. As the core component connecting the upper and lower machine bodies, it enables the excavator to adjust its working direction; without it, the machine cannot change the direction of operation at all.

   However, many operators neglect its maintenance and only repair it when the raceway is worn out, which not only costs tens of thousands of dollars but also results in days of downtime. This article thoroughly explains its structure, risk factors, brand comparisons, and maintenance methods in plain language — even beginners can understand it, helping the slewing ring rotate smoothly and last longer!
