Abstract: : Excavators are one of the most widely used types of heavy equipment due to their ability to operate in tight spaces with high efficiency. One crucial component in supporting excavator performance is the hydraulic system, which functions to move main parts such as the boom, arm, and bucket through fluid pressure. Disruptions in this system can reduce productivity and trigger damage to other components. This study aims to evaluate whether the hydraulic system on the Caterpillar 305.5E2 Excavator unit works optimally and according to technical specifications. Testing was carried out through two main methods, namely pressure tests and operational tests, with the help of pressure gauges and stopwatches. The test results showed that all main functions of the boom, stick, bucket, blade, swing, and travel can operate properly without symptoms of damage or delayed response. Although the hydraulic system may still be operationally functioning normally, there may be indications of internal damage or improper pressure adjustments, which could affect the unit’s long-term performance. Therefore, further technical evaluation is required as part of a preventive maintenance program.
