Common Causes and Solutions for Bucket Drift Issue
#1
Users of excavators or skid steers often report a bucket drift issue, where the bucket continues to move slowly after the operation is completed. This typically relates to problems within the hydraulic system, particularly involving the control valve, seals, and the state of the hydraulic oil.
Common Causes
  1. Hydraulic Valve Issues: The bucket drift could be caused by a sticking or aging hydraulic control valve that fails to fully deliver the control signal, resulting in unwanted movement of the bucket.
  2. Seal Wear: Over time, the seals in the hydraulic system can degrade or wear out, leading to hydraulic fluid leakage, which in turn affects the system's performance and causes drift.
  3. Hydraulic Oil Quality: Poor quality hydraulic oil, or contamination of the oil over time, can impact system pressure and flow, which may lead to drift.
  4. Electronic Control System Malfunctions: In machines with electronic control systems, faulty electrical signals or sensor issues can cause improper control of the hydraulic valves, contributing to drift.
Solutions
  1. Check Hydraulic Valves: Inspect the hydraulic control valve to ensure it is functioning properly. Clean or replace any malfunctioning valves, as internal parts such as springs may wear out or fail.
  2. Inspect Seals: Regularly check the seals of hydraulic cylinders and lines for any signs of wear or leakage. If seals are found to be damaged or aged, replace them promptly.
  3. Change Hydraulic Oil: If the hydraulic oil has not been changed for a long time or is contaminated, it is important to replace it with clean, high-quality hydraulic oil to maintain proper system function.
  4. Check the Electronic Control System: For machines with electronic control systems, check the wiring and sensors for any loose connections or faults. Ensure that the electrical signals are properly transmitted to avoid improper control of the hydraulic system.
Conclusion
Bucket drift is commonly caused by hydraulic system issues, particularly related to the control valve, seals, hydraulic oil, and the electronic control system. Regular maintenance and checks of these critical components can help resolve the issue and ensure the machine operates smoothly.
