Bobcat T190 Hydraulic System Capacity and Performance

[MikePhua]

The Bobcat T190 compact track loader, introduced in the early 2000s, is renowned for its robust performance and versatility in various construction and landscaping tasks. A critical component of its efficiency is its hydraulic system, which powers essential functions such as lifting, tilting, and operating attachments.
Hydraulic System Specifications

• Hydraulic Pump Flow: The T190 is equipped with a hydraulic pump that delivers a flow rate of 16.3 gallons per minute (GPM) at 3,300 pounds per square inch (psi) system relief pressure. This setup ensures sufficient power for standard operations.
  
• Auxiliary Hydraulic Flow:
  • Standard Flow: 16.9 GPM
    
  • High Flow: Up to 26.4 GPM
    

These flow rates are crucial for operating various attachments, with high-flow hydraulics providing enhanced performance for demanding tools like mulchers and cold planers.
Hydraulic Fluid Capacity

• System Capacity: Approximately 9.0 gallons
  
• Reservoir Capacity: Around 4.8 gallons
  

It's important to note that draining and replacing hydraulic fluid in the T190 may not remove all the old fluid due to the system's design. To achieve a more thorough fluid change, operators often cycle the hydraulic system through various functions to expel residual fluid before refilling with fresh oil.
Maintenance Tips

• Fluid Type: Utilize synthetic hydraulic fluid to ensure optimal performance and longevity of the hydraulic components.
  
• Regular Checks: Consistently monitor hydraulic fluid levels and inspect for leaks to maintain system efficiency.
  
• Filter Maintenance: Replace hydraulic filters as per the manufacturer's recommendations to prevent contamination and ensure smooth operation.
  

Conclusion
The hydraulic system of the Bobcat T190 is designed to deliver reliable performance across a range of tasks. By adhering to proper maintenance practices and understanding the system's capacities, operators can ensure the longevity and efficiency of their equipment.
