Bobcat 763 Lift/Tilt Troubleshooting and Solutions - MikePhua - 07-04-2025
Issues with the lift and tilt system on the Bobcat 763 skid steer can arise from several factors, including hydraulic system malfunctions, control valve problems, or electrical issues. Here are the key steps to troubleshoot and resolve the problem:
1. Check Hydraulic Fluid Levels and Quality
Hydraulic system issues are a common cause of lift and tilt problems on the Bobcat 763. Start by checking the hydraulic fluid level to ensure it’s at the proper level. If the fluid is low, the system may not generate enough pressure, causing lifting and tilting issues. Also, inspect the quality of the hydraulic fluid—if it’s degraded or contaminated, it can affect system performance.
2. Inspect Hydraulic Pump and Solenoid Valve
A malfunctioning hydraulic pump or a stuck solenoid valve can prevent the lift and tilt functions from working correctly. Check whether the hydraulic pump is operating as expected and ensure that the solenoid valve is not blocked or stuck. If the solenoid valve is faulty, it may need cleaning or replacement.
3. Check Control Lines and Fittings
The control lines and fittings within the hydraulic system may wear out or corrode, leading to issues with lift and tilt functionality. Inspect all hydraulic lines and connections for leaks, looseness, or damage. If you find any damaged lines, replace them promptly.
4. Inspect the Electrical System
If the hydraulic system appears to be functioning properly, the issue might lie with the electrical system. Check the electrical switches and wiring that control the lift and tilt functions. Ensure the switches are operating correctly and check for secure electrical connections. Faulty electrical connections can prevent the hydraulic system from functioning properly.
5. Inspect the Drive System
If both the hydraulic and electrical systems are working fine, the drive system might be at fault. Check the relevant drive components for wear or damage. For instance, inspect the hydraulic cylinders for leaks or any mechanical blockages that could be preventing movement.
6. Check Hydraulic Filters
A clogged hydraulic filter can also restrict fluid flow and impair lift and tilt operations. Regularly check and replace the hydraulic filter to ensure the fluid can flow freely through the system.
Conclusion
When the Bobcat 763 experiences issues with its lift and tilt functions, start by checking the hydraulic fluid levels and quality, as well as the hydraulic pump, solenoid valve, and control lines. If the hydraulic system is functioning well, move on to inspecting the electrical system and drive components. By systematically troubleshooting the machine, you can identify and resolve the issue, restoring proper lift and tilt functionality.
