320E Excavator Breaker Common Issues and Solutions
#1
The CAT 320E Excavator's breaker (Hydraulic Breaker) is one of its essential attachments, widely used in demolition, excavation, and breaking tasks. While the breaker is highly efficient, it may encounter several common issues as it is used over time. This article explores the common problems with the 320E Excavator breaker and provides solutions to help users efficiently troubleshoot and extend the life of the equipment.
Common Issues and Symptoms
  1. Breaker Not Operating or Low Power
    This is one of the most common issues, where the breaker either fails to start or starts with insufficient power, making it ineffective for breaking materials. This could be caused by hydraulic system failure, internal wear in the breaker, or low hydraulic fluid levels.
  2. Frequent Sticking or Abnormal Vibration
    During operation, the breaker may experience sticking, abnormal vibrations, or breakage, leading to unsmooth operation. Such issues are usually caused by wear or damage to internal components like the piston, bushings, or other parts inside the breaker.
  3. Hydraulic Oil Leaks
    Hydraulic oil leakage can lead to unstable oil pressure, affecting the breaker’s normal function. This is typically caused by worn or damaged seals, which may result in oil loss and affect the performance of the equipment.
  4. Overheating or Low Temperature
    Prolonged use of the breaker can lead to overheating, which may affect the hydraulic system’s normal operation. Conversely, low temperatures can increase the viscosity of the hydraulic oil, affecting fluid flow and the breaker’s performance.
Solutions to Common Issues
  1. Inspect the Hydraulic System and Oil Levels
    When the breaker fails to operate properly, start by checking the hydraulic system. Inspect the oil levels and the quality of the oil to ensure it is clean and sufficient. If the oil is contaminated or old, replace it and clean the oil filters. Check for leaks in the hydraulic pump and lines to ensure proper oil flow.
  2. Replace Worn Internal Components
    For issues like sticking or abnormal vibration, inspect the internal parts of the breaker, such as the piston and bushings, for wear. If these parts are excessively worn or damaged, replace them promptly. Regular inspection and maintenance of the internal components are crucial to prevent further problems.
  3. Replace Seals
    If oil leakage is the issue, check the seals. Damaged or worn seals need to be replaced to ensure the hydraulic system remains sealed and prevent oil leaks. Use high-quality seals that meet specifications to maintain proper sealing.
  4. Monitor Breaker Temperature
    To prevent overheating or performance issues due to temperature, regularly monitor the breaker’s temperature. In hot weather, ensure the cooling system is functioning correctly. If the temperature is too high, reduce the operating time or add extra cooling. In cold conditions, ensure the hydraulic oil flows properly and avoid excessively low temperatures.
  5. Regular Maintenance and Servicing
    To ensure long-term efficient operation, follow the manufacturer’s guidelines for routine maintenance. Regularly check all connecting parts, lubricate them, and make sure the breaker is in optimal working condition.
Conclusion
The 320E Excavator breaker is a highly effective tool, but like any heavy equipment, it may encounter common issues over time. By regularly inspecting the hydraulic system, replacing worn components and seals, and maintaining the proper operating temperature, users can extend the breaker’s lifespan and ensure continued high performance. In case of complex issues, it is recommended to consult a professional technician for further inspection and repair.
