The Bobcat T190 skid steer loader is a highly regarded machine, commonly used in construction, agriculture, and various industries. Its strong performance and efficient hydraulic system make it an excellent choice for tough tasks. Recently, a user on Panswork forum mentioned experiencing issues with the auxiliary hydraulics system while using the T190. This article will summarize these issues and provide solutions to help resolve them.
Issue Description: Auxiliary Hydraulics Malfunction
The user reported that the auxiliary hydraulics system on their Bobcat T190 was not functioning correctly, making it impossible to operate certain attachments. The auxiliary hydraulics system is crucial for providing additional power to attachments like buckets, cutters, and augers. When the system fails, it prevents attachments from operating properly, which affects overall work efficiency.
Common Auxiliary Hydraulics Issues
The auxiliary hydraulics system of the Bobcat T190 is a critical component for efficient operation, allowing the loader to power attachments. When the hydraulic system malfunctions, it not only affects the performance of attachments but can also lead to further damage to the equipment. Regular maintenance, including checking fluid levels, replacing seals and filters, and testing key components, can help prevent issues with the hydraulic system. If the problem persists or is too complex to handle on your own, professional assistance will be the best way to resolve it.

Common Auxiliary Hydraulics Issues
- Insufficient Hydraulic Flow
The user mentioned that the hydraulic system was not supplying enough flow, resulting in a lack of power for the attachments. This could be due to a malfunctioning hydraulic pump or a clogged hydraulic line.
- Hydraulic Oil Leaks
Another frequent issue is hydraulic oil leaks. Leaks can occur in hoses, fittings, or seals. Oil leakage not only disrupts system performance but can also cause damage to other components.
- Control Valve Failure
The control valve is an essential part of the hydraulic system. If the control valve fails, hydraulic fluid may not be directed properly to the attachments, rendering them inoperable.
- Hydraulic Oil Contamination
Contaminated hydraulic oil can cause internal component wear, which may lead to damage to the hydraulic pump and valves. Contamination usually comes from dirt, moisture, or dirty oil.
- Check Hydraulic Oil and Quality
Ensure the hydraulic oil is at the correct level and check its condition. If the oil is contaminated or at a low level, replace it and clean the system. Dirty oil can cause serious issues within the system.
- Inspect Hydraulic Hoses and Fittings
Check all hydraulic hoses and fittings for leaks. Tighten any loose fittings or replace damaged hoses. If leaks are severe, seals may need to be replaced.
- Test the Hydraulic Pump and Flow Control
Test the hydraulic pump and flow control systems to ensure they are operating correctly. If the pump's output pressure and flow are below normal levels, the pump may need repair or replacement.
- Inspect the Control Valve
Inspect the control valve to ensure it's functioning properly. Cleaning or checking the valve, or inspecting the electrical connections to solenoid-controlled valves, can help identify issues. If the control valve is faulty, it may need to be replaced.
- Replace or Clean Hydraulic Filters
Regularly replace hydraulic filters to prevent contaminants from entering the system and causing issues. Depending on the frequency of use, the filters should be changed periodically to maintain clean hydraulic oil.
- Seek Professional Help
If the above steps do not resolve the issue, it may be time to consult a professional technician. Hydraulic systems require specialized knowledge and tools for proper diagnosis and repair, especially when dealing with complex issues.
