2014 Bobcat SR210 Auxiliary Hydraulic System Troubleshooting Guide
#1
A malfunctioning auxiliary hydraulic system on the 2014 Bobcat SR210 skid steer can significantly impact the machine’s versatility, especially when using hydraulic attachments. If the auxiliary hydraulics are not working properly, it can lead to reduced work efficiency and even require downtime for repairs. Based on discussions from the panswork forum, this article summarizes the common causes and troubleshooting steps for auxiliary hydraulic system issues, helping users quickly identify and resolve the problem.
Common Auxiliary Hydraulic Issues
  1. No Hydraulic Output: One of the most common problems, typically caused by issues with the hydraulic pump, control valve, or hoses.
  2. Weak or Unstable Hydraulic Output: The auxiliary hydraulic system might provide insufficient or unstable pressure, often due to poor oil quality, a clogged filter, or worn hydraulic components.
  3. Hydraulic Attachments Not Working Properly: Sometimes the hydraulic attachments themselves may fail to operate, which could be caused by electrical issues or a mismatch in the control system.
Troubleshooting Steps
  1. Check Power and Switches for Auxiliary Hydraulics: Begin by ensuring the skid steer’s power is on, and the auxiliary hydraulic system switch is set correctly. In some cases, the hydraulic system might be turned off or not properly engaged.
  2. Check Hydraulic Oil Level and Quality: A common cause of hydraulic system failure is insufficient oil or poor oil quality. Check the hydraulic oil level to ensure it’s within the normal range. Also, inspect the oil’s cleanliness and quality. If the oil is contaminated or degraded, it should be replaced with fresh oil.
  3. Check Hydraulic Filter: Over time, the hydraulic filter may become clogged, leading to insufficient pressure or unstable hydraulic output. Inspect the filter for dirt and debris, and replace or clean it as necessary.
  4. Inspect the Control Valve and Electrical System: The auxiliary hydraulic system is typically controlled by an electro-hydraulic valve. Check whether the control valve is operating correctly and that the electrical connections are intact. Faulty control valves or poor electrical connections could be causing hydraulic output issues.
  5. Check the Hydraulic Pump: A malfunctioning hydraulic pump is a common cause of no hydraulic output. Inspect the hydraulic pump’s operational status to ensure it’s working properly. Internal damage to the pump or issues with its drive system could be preventing hydraulic fluid from circulating properly.
  6. Inspect Hydraulic Hoses and Lines: Check all hydraulic hoses and lines for leaks, kinks, or damage. Damaged hoses can obstruct hydraulic fluid flow, which negatively impacts the system’s performance.
Solutions
  • If low oil levels or poor oil quality are identified, replace the hydraulic oil and clean the filter.
  • If the control valve or electrical system is faulty, repair or replace the relevant components and ensure proper electrical connections.
  • For hydraulic pump or hose issues, check for damage and replace any faulty components.
Conclusion
Auxiliary hydraulic system failures can stem from various issues, ranging from poor hydraulic oil quality to problems with the control valve and hydraulic pump. Regular maintenance, including checking hydraulic oil, filters, valves, and pumps, is crucial for ensuring efficient system performance. If troubleshooting the issue proves difficult, it’s recommended to seek professional technical support to restore the equipment to optimal working condition.
